Its convenience, speed, low cost and versatility are being exploited on a daily basis in ever-changing ways. Together with its capacity to transform existing businesses, promote new businesses and facilitate exchange of information and data, its other striking attribute has been the speed with which this new technology has spread throughout the global economy.Keywords:The internet;Real Estate;ApplicatedThe number of computer hosts grew by more than ten-fold between 1995 and early 1999. The number of Web sites increased almost 100-fold, to over two million, between 1995 and 1998.By the year 2000, there will be approximately 400-500 million Internet users in the world, and the total number of Web sites will exceed five million.This new technology has the potential for affecting the real estate industry directly and indirectly. Directly, it may become a tool that allows a real estate business to expand its information and sales network. Indirectly, it may change the location equation where and how firms do business which in turn will affect the role of firms involved in real estate development, investment and transactions.Measuring the Spread of the WebThere are few reliable published statistics on Internet or Web use, and statistics reported by different analysts are often inconsistent. Our discussion of the Web and real estate is based on limited information from surveys and on examination of Web sites rather than on more comprehensive data. We have built our overview of the role of the World Wide Web and real estate by examining a variety of sources(including trade publications, existing Web sites, and our own survey of selected real estate firms)From E-mail to E-commerceBefore the advent of the World Wide Web, the Internet existed mostly for the purposes of e-mail, data transfers, newsgroups and bulletin boards, and its reach was limited primarily to the academic and the defense community. The technology itself was not particularly user-friendly, the network speed was not very high, the medium was limited to text and data, and accessing information was cumbersome and time-consuming. The browser technology greatly simplified usage, enabled multimedia information, and created interactive possibilities. The technology brought together TV entertainment, library information, news bulletins, communication and data in one desktop machine.Although initially the greatest patrons of the Internet were the academic community, the commercial sector quickly caught on to the potential of the Web. The private sector saw in the Web an opportunity to widen its marketing reach, lower costs of information dissemination, improve customer relations, and ultimately to conduct sales. Existing private sector Web sites can be roughly categorized into three types, as summarized. The most basic level is for simple information dissemination. The firm registers a Web site and develops a page giving basic company information. The second stage is an expansion of information, marketing goods and services or providing other customer information. The third stage is the addition of transactions tothe activities possible on the Web site.Most business sites at present are in Stage 2. The use of the World Wide Web for detailed information dissemination, and marketing has had several advantages. For the firm, marketing, information dissemination and customer services on the Web can be monitored and analyzed with some details unavailable from conventional methods of marketing using other media. Internet tools can now provide a firm with data on who accessed the site, which pages were visited most, heavily, from where and for how long. This information contributes to improved measures of the results of promotional efforts. The promotional costs associated with the Internet have also been very low. For example, in direct mail marketing, to send a one-page color brochure to 5,000 random addresses will cost upwards of $2,500. The cost of setting up a Web site could be one-tenth of this amount or less (although tracking and analysis can quickly add to the cost)?Many different sectors, including real estate, have found the Internet to be both efficient and cost-effective as a marketing device.The next logical step - a full-fledged office/store on the Web with transaction capability and commerce on the Internet is now being attempted in varying degrees depending on the firm's area of business. Retail sites selling products between $10 and $100, the kind that are traditionally part of a direct mail sales catalog, seem to be the ones having the greatest success(although 4% of sites sell products over $10,000 and another 13% sell products ranging from $100 to$9,999)?A number of retail sites have also harnessed a secondary revenue stream from advertising. Advertising revenues on the Web have crossed the billion-dollar mark and total Internet generated revenue will approach$100 billion this year.Consumers' Use of the WebSurveys of consumers using the Web suggest that a Web site does notsubstitute for the more traditional forms of business, but can greatly facilitate the run-up to the final transaction. The most common use of the Web is for information searching, closely followed by work-related uses, education, and entertainment. A significant majority of those that use the Web for shopping do so to carry out detailed research on product information(90%)and to do price comparisons(85%). This more often leads to purchases through normal channels(67%). Most of the online purchases tend to be of items that are standardized-four of the five top items bought on the Web, according to survey, are software, books, hardware and music (the fifth is travel). More than half of consumers who make purchases on the Web spend less than $500 in a six-month period.The demographics of Web users vary widely in age and income. Surveys by Georgia Tech, Active Media and Web indicate that the average age of Web users is 35 years, with average household income $67,000. Most are college educated (65%). A high proportion of the respondents (42%) has accessed real estate sites.Limits to the Web - Some "Catches" to the New Technology New technology is frequently a mixed blessing, and the World Wide Web is no exception. Apart from the teething troubles that any new technology faces and the time, as well as resources needed to learn, adapt and master it, the Web poses some unique issues and problems of its own. Consumers today are facing information overload of taxing proportions. It is not always easy, or even possible, to locate the relevant information on the Web, despite sophisticated search engines. Once the site is located, fancy graphics, complex linkages, labyrinthine routings, and a lot of irrelevant information may overwhelm the consumer - in short, poor and confusing site design can reduce the site's effectiveness.From the point of view of the business, there are two commonly heardcomplaints. First, the business may find that its site does not figure prominently on search results, limiting the number of customers reached. Second, for many firms, Web initiated leads are as yet few and far between. Real Estate Web SitesReal Estate firms and related businesses were among the early private sector pioneers of Internet use and have had a fast growing presence on the Web. presence on the Web. One example of the real estate sector's presence on the Internet in its pre-World Wide Web incarnation was the real estate classified bulletin board of Prodigy, the online service, which had listings for homes and other real estate. A few real estate related Web sites started in 1994 (generally regarded as the inaugural year of the Web). The New York City Real Estate Guide Web site, created in the summer of 1994, was one of the first to offer free access to the latest New York real estate information. By the summer of 1995, the site was receiving more than 100,000 inquiries a month.The real estate industry registered its entry on the Web in a dramatic way in 1995. By the end of that year there were close to 4,000 real estate Web sites. The content matter of the sites, as well as the mix of real estate related firms on the Web have changed over time. Initially, quite a few of the sites were residential real estate brokerages and listing guides, but fairly rapidly the list expanded to include commercial and retail listings, mortgage brokers,appraisers, architects, real estate attorneys, developers, construction firms, and suppliers. As investment vehicles for real estate expanded, REITs, publicly held firms, and investment advisors also added Web sites.The early real estate broker Web sites quickly took advantage of the unique features of the Web. Prospective customers could find out what properties were for sale or rent, look up detailed descriptions of each listing, view photographs and floor plans, and contact the broker by e-mail. Viewerscould also look up statistical and data reports on conditions in various geographical areas and on emerging macroeconomic trends.Ever since then, the real estate industry has been among the most enthusiastic users of the Web, by some measures accounting for 4% to 6% of commercial Web sites. A survey conducted by Real Estate Broker's Insider in early 1998 confirmed that nearly 95% of the respondents/brokers had a Web site, and more than 90% of the housing stock on sale at a given time is now listed on the Web. Indeed, because of the dispersed, localized nature of the role of information in real estate, the prospective gains from information dissemination, comparability, and Web links were particularly significant in real estate.For much of the real estate sector, the Internet generates not so much the actual transactions themselves, but creates initial leads that are later followed by transactions, purchases and sales. Web sites frequently lead to contacts that are then nurtured through telephone and person-to-person meetings. For residential real estate, Web activity includes residential searches, housing details, and pricing information (both on houses and mortgages), with follow-up contact with brokers. Real estate-related transactions are seen in the hospitality industry (making reservations for hotels and vacation homes and in online mortgage applications). Mortgage and home loan finance companies report both inquiries from mortgage shoppers who obtained initial information from their Web sites, as well as closing of loans through the Web, lead to great savings in time and overhead costs.It is not just the real estate professionals who are enthusiastic about their Internet presence, judging it to be as effective as print and radio advertising. Mortgage shoppers, homebuyers and vacation rental seekers as well applaud, in particular, the convenience it brings to the entire process of searching, researching, comparing, communicating and transacting business.Beyond these sectors, many other types of real-estate related firms are using the Web to broaden their market areas, increase the depth of their marketing, and to provide a range of services to existing customers. Commercial brokers provide not only information on available sites but also on market conditions for different locations and sometimes more in-depth economic analysis of a region. REITs and other investment firms provide detailed information on their products as well as background market or economic information. Public companies provide up-to-date stock quotes and quarterly and annual reports on the Web.Web Penetration and Use: The Experience of Leading Real Estate Firms We conducted a limited survey of a sample of leading real-estate related firms in the US and California. Responses from approximately 60 of these firms showed that over four-fifths had Web Sites by March 1999. 2 Of those with Web sites, one-third had inaugurated their sites by the end of 1996. Among the earliest with a Web presence were brokers, investment firms, lenders, business and financial services firms, law firms, residential developers, and a trade organization. Another third of the group were newcomers, with sites inaugurated in 1998 or early 1999. Commercial developers were prominent among this group, with residential developers, consultants and advisors, lenders, REITs and investment firms also among this group. Those without sites were more likely to be privately held firms with a relatively narrow base of activity (for example, a commercial developer centered in the San Francisco Bay Area)?Most with Web sites used their site to provide information about the company and to market services. In addition, about one-third marketed property from their site, providing detailed information on the characteristics of buildings available, surrounding communities, and other related data. Other Web site uses include employee recruiting, providing information formembers or investors, and disseminating related information on topics such as regulations or real estate markets.What does the Web specifically do for Real Estate?According to Activemedia, an internet research company, some of the sectors experiencing the greatest growth in terms of their presence on the Web in 1998 were computer hardware and software, real estate, publishing and information, finance and Internet services. A significant initial motivation for this rush for the Web is provided by, what can be termed, the "tiptoe" effect. The first ones on the Web had an additional advantage over those who did not; information on their services, products, home listings now be accessed conveniently by those with computers. The low setup cost, however, and the potential disadvantage of not having a Web presence has propelled others in the profession to set up their own sites.Real estate shares in some of the basic advantages of the Web mentioned earlier, such as ease of marketing, communication and feedback from clients, lowered costs of operations and convenience of customer service and support. In addition, the Web provides positive features specific to the real estate industry.Key elements include the following.1.Increased geographic reach.The Web has dramatically increased the geographic reach of both buyers and sellers. Although the "local" aspect of real estate will perhaps never be whittled away completely, there is no doubt that inquiries about properties can now emanate from far away to a much greater degree than before. This, in turn, potentially increases the size and "depth" of the market and makes it more efficient.2.Capability of visualization.In some sense, increased geographic reach has become possible due tothe other emergent feature of the Web, the capability of visualization. In its most state-of-the-art form, Web sites now allow prospective buyers to take virtual tours of homes, resorts, hotels and convention centers.3.Reduced transaction costs.The Web may reduce transactions costs. This has been particularly apparent in the case of mortgages. According to Fannie Mae, 1.5% of all mortgages were handled online this past year. The Web-attributable features that make this kind of a transaction possible are instantaneous comparability, interactive capability, online calculation, online applications, and continuous updating of the sites.4.Improved information dissemination.The Web offers broad opportunities for increasing the scope and depth of information provided by many different types of firms. A well constructed home page gives an overview of a firm's range of services or activities. Links allow the customer or client to learn much more detail about the selected items of most interest, while ignoring less relevant pieces of information. A number of sites take advantage of the ability to link to resources beyond the company's Web pages, linking customers and clients to related Web resources.Unlike retail sectors, such as books and computer hardware, the Web as yet has not become a threat to the "middle man" role of many real estate firms. Instead, it is more likely to be used as a means of expanding services offered or locations served. However, in the long term, the Web and related Internet technology have the potential to change the structure of business activity, which in turn will affect the demand for real estate in type if not in quantity. For example, some retailers already have closed stores while expanding sales on the Web. Also, the Internet has been seen as one factor allowing the decentralization of office space. These trends to date have notled to a decline, but rather to a redistribution in the demand for office, retail and warehouse space.These are summarized .Speculation on Potential Impact of Internet on Real Estate Industry.1.Shortening of Transaction Cycle2.Precise Market Targeting3.Transformed Competition4.Cost savings:a)Marketing,b)Sales,c)Operation5.Possibility of Disintermediation;Lowering of Commissionsbination of Comparison Shopping and Direct Sales7.Access to MBS Secondary MarketHow to Find the Real Estate Sector on the WebThere are a few key sites that can be used to access the broad range of real-estate related Web sites.

第 2 章项目生命周期与组织项目与项目管理都是在比项目本身更大的环境中进行的。
理解这个大环境,有助于确保项目的执行符合企业目标,项目的管理符合组织既有的实践方法论。
本章将介绍项目的基本结构和其他重要的宏观事项,包括项目如何影响持续性的运营,直接项目团队以外的干系人如何影响项目,以及组织结构如何影响项目的人员配备、管理和执行。
本章包括以下主要部分:2.1 项目生命周期——概述2.2 项目与运营2.3 项目干系人2.4 组织对项目管理的影响2.1 项目生命周期——概述项目生命周期是通常按顺序排列而有时又相互交叉的各项目阶段的集合。
阶段名称和数量取决于参与项目的一个或多个组织的管理与控制需要、项目本身的特征及其所在的应用领域。
生命周期可以用某种方法加以确定和记录。
可以根据所在组织或行业的特性,或者所用技术的特性,来确定或调整项目生命周期。
虽然每个项目都有明确的起点和终点,但其具体的可交付成果以及项目期间的活动会因项目的不同而有很大差异。
无论项目涉及什么具体工作,生命周期都能为管理项目提供基本框架。
2.1.1 项目生命周期的特征项目的规模和复杂性各不相同,但不论其大小繁简,所有项目都呈现下列生命周期结构(见图 2-1):图 2-1 项目生命周期中典型的成本与人力投入水平通用的生命周期结构通常具有以下特征:成本与人力投入在开始时较低,在工作执行期间达到最高,并在项目快要结束时迅速回落。
这种典型的走势如图 2-1 中的虚线所示。
干系人的影响力、项目的风险与不确定性在项目开始时最大,并在项目的整个生命周期中随时间推移而递减(见图 2-2)。
在不显著影响成本的前提下,改变项目产品最终特性的能力在项目开始时最大,并随项目进展而减弱。
图 2-2 表明,变更和纠正错误的代价在项目接近完成时通常会显著增高。
在通用生命周期结构的指导下,项目经理可以决定对某些可交付成果施加更有力的控制。

Concrete Construction matterT. Pauly, M. J. N. PriestleyAbstractViewed in terms of accepted practices, concrete construction operations leave much to be desired with respect to the quality, serviceability, and safety of completed structures. The shortcomings of these operations became abundantly clear when a magnitude 7.6 earthquake struck northern Paki-stan on October 8, 2005, destroying thousands of buildings, damaging bridges, and killing an esti-mated 79,000 people. The unusually low quality of construction operations prevalent was a major cause of the immense devastation.Keywords: Concrete Placing Curing Construction TechnologyPlacing ConcreteIf concrete is placed in the surface, the sur-face should be filled with water sufficiently to prevent it from absorbing the concrete of its water. If fresh concrete is to be placed on or nearby to concrete that has solidified, the surface of the placed concrete should be cleaned absolutely, preferably with a high-pressure air or water jet or steel-wire brushes. The surface should be wet, but there should be no much water. A little quantity of cement grout should be brushed over the whole area, and then followed immediately with the application of a 1/2-in Layer of mortar. The fresh concrete should be placed on or against the mortar.In order to decrease the disintegration re-sulting from carriage after it is placed. The con-crete should be placed as nearly as probably in itsfinal point. It should be placed in layers to permit uniform compaction. The time interval between the placing of layers should be limited to assure perfect bond between the fresh and previously placed concrete.In placing concrete in deeper patters, a ves-sel should be used to limit the free fall to not over 3 or 4 ft, in order to prevent concrete disintegra-tion. The vessel is a pipe made of lightweight metal, having adjustable lengths and attached to the bottom of a hopper into which the concrete is deposited. As the patters are filled, sections of the pipe may be removed.Immediately after the concrete is placed, it should be compacted by hand pudding or a me-chanical vibrator to eliminate voids. The vibrator should be left in one position only long enough to reduce the concrete around it to a plastic mass; then the vibrator should be moved, or disintegra-tion of the aggregate will occur. In general, the vibrator should not be permitted to penetrate concrete in the prior lift.The mainly advantage of vibrating is that it permits the use of a drier concrete, which has a higher strength because of the reduced water content. Among the advantages of vibrating con-crete are the following:1.The decreased water permits a reduction in the cement and fine aggregate because less cement paste is needed.2.The lower water content decreases shrinkage and voids.3.The drier concrete decreases the cost of finishing the surface.4.Mechanical vibration may replace three to eight hand puddles.5.The lower water content increases the strength of the concrete.6.The drier mixture permits theremoval of some patters more quickly, which may reduce the cost of patters.Curing ConcreteIf concrete is to gain its maximum strength and other desirable properties, it should be cured with adequate moisture and at a favorable tem-perature. Failure to provide these conditions may result in an inferior concrete.The initial moisture in concrete is adequate to hydrate all the cement, provided it is not should replace the moisture that does evaporate. This may be accomplished by many methods, such as leaving the patters in place, keeping the surface wet, or covering the surface with a liquid curing compound, which comes being to a water-tight membrane that prevents the escape of the initial water. Curing compounds may be applied by brushes or pressure sprayers. A gallon will cover 200 to 300 sq ft.Concrete should be placed at a temperature not less than 40 or more than 80°F.A lower tem-perature will decrease the rate of setting, while ahigher temperature will decrease the ultimate strength.Placing Concrete in Cold WeatherWhen the concrete is placed during cold weather, it is usually necessary to preheat the water, the aggregate, or both in order that the ini-tial temperature will assure an initial set and gain in strength .Preheating the water is the most ef-fective method of providing the necessary tem-perature. For this purpose a water reservoir should be equipped with pipe coils through which steam can be passed, or steam may bedischarged directly into the water, several outlets being used to given better distribution of the heat.When the temperatures of the mixtures are known, some specific charts may be used to cal-culate the temperature of concrete. A straight line pass all three scales, passing through every two known temperatures, will assure the determina-tion of the third temperature. If the surface of sand isdry, the fact lines of the scales giving the temperature of concrete should be used. However, if the sand contains about 3 percent moisture, the dotted lines should be used.Specifications usually demand that freshly placed concrete shall be kept at a temperature of not less than 70°F for 3 days or 50°F for 5 days after it is placed. Some proper method must be provided to keep the demanded temperature when the cold weather is estimated.Reinforcing steels for concreteCompared with concrete, steel is a high strength material. The useful strength of ordinary reinforcing steels in tension as well as compres-sion, i.e., the yield strength, is about 15 times the compressive strength of common structural con-crete, and well over 100 times its tensile strength. On the other hand, steel is a high-cost material compared with concrete. It follow that the two materials are the best used in combination if theconcrete is made to resist the compressive stresses and the compressive force, longitudinal steel reinforcing bars are located close to the ten-sion face to resist the tension force., and usually additional steel bars are so disposed that they re-sist the inclined tension stresses that are caused by the shear force in the beams. However, rein-forcement is also used for resisting compressive forces primarily where it is desired to reduce the cross-sectional dimensions of compression members, as in the lower-floor columns of multi-story buildings. Even if no such necessity exits , a minimum amount of reinforce- ment is placed in all compression members to safeguard them against the effects of small accidental bending moments that might crack and even fail an unre-inforced member.For most effective reinforcing action, it is essential that steel and concrete deform together, i. e., that there be a sufficiently strong bond be-tween the two materials to ensure that no relative movements of the steel bars and the surrounding concrete occur. This bond is provided by the rela-tively large chemical adhesion which develops at the steel-concrete interface, by the natural roughness of the mill scale of hot-rolled rein-forcing bars , and by the closely spaced rib-shap-ed surface deformations with which reinforcing bars are furnished in order to provide a high de-gree of interlocking of the two materials.Steel is used in two different ways in con-crete structures: as reinforcing steel and as prestressing steel .reinforcing steel is placed in the forms prior to casting of the concrete. Stresses in the steel, as in the hardened concrete, are caused only by the loads on the structure, except for possible parasitic stresses from shrinkage or similar causes. In contrast, in priestesses concrete structures large tension forces are applied to the reinforcement prior to letting it act jointly with the concrete in resistingexternal.The most common type of reinforcing steel is in the form of round bars, sometimes called rebars, available in a large range of diameters,from 10 to 35 mm for ordinary applications and in two heavy bar sizes off 44 and 57 mm these bars are furnished with surface deformations for the purpose of increasing resistance to slip be-tween steel and concrete minimum requirements for these deformations have been developed in experimental research. Different bar producers use different patterns, all of which satisfy these requirements.Welding of rebars in making splices, or for convenience in fabricating reinforcing cages for placement in the forms, may result in metal-lurgical changes that reduce both strength and ductility, and special restrictions must be placed both strength and ductility, and special restric-tions must be placed both on the type of steel used and the welding procedures the provisions of ASTM A706 relatespecifically to welding.In reinforced concrete a long-time trend is evident toward the use of higher strength materi-als, both steel and concrete.Reinforcing bars with 40ksi yield stress , almost standard 20 years ago , have largely been replaced by bars with 60ksi yield stress , both because they are more economical and because their use tends to reduce congestion of steel in the forms .The ACI Code permits reinforcing steels up to Fy=80ksi. Such high strength steels usually yield gradually but have no yield plateau in this situation the ACI Code requires that at the speci-fied minimum yield strength the total strain shall not exceed 0.0035 this is necessary to make cur-rent design methods, which were developed for sharp-yielding steels with a yield plateau, appli-cable to such higher strength steels. there is no ASTM specification for deformed bars may be used , according to the ACI Code , providing they meet the requirements stated under special circumstances steel in this higher strength range has its place, e.g., in lower-story columns of high-rise buildings.In order to minimize corrosion of rein-forcement and consequent spelling of concrete under sever exposure conditions such as in bridge decks subjected to deicing chemicals , galvanized or epoxy-coated rebars may be specified.Repair of Concrete StructuresReinforced concrete is generally a very du-rable structural material and very little repair work is usually needed. However, its durability can be affected by a variety of causes, including those of design and construction faults, use of inferior materials and exposure to aggressive en-vironment. The need for a repair is primarily dic-tated by the severity of the deterioration as de-termined from the diagnosis. Good workmanship is essential if any thing more than just a cosmetic treatment to the creation is required.1. performance requirements of repair systemHaving established the causes of the defect by carefully diagnosing the distress, the next step should be to consider the requirements of the re-pair method that will offer an effective solution to the problem (see fig.).①DurabilityIt is important to select repair materials that provide adequate durability. Materials used for the repair job should be at least as durable as the substrate concrete to which it is applied.②Protection of steelThe mechanism of protection provided to the reinforcing depends on the type of repair ma-terials used. For example, cementations materials can protect the steel from further corrosion by their inhibitive effect of increasing the alkalinity of the concrete, whereas epoxy resin mortars can give protection against the ingress of oxygen,moisture and other harmful agents.③Bond with substrateThe bond with the substrate must produce an integral repair to prevent entry of moisture and atmospheric gases at the interface. With most re-pair materials, the bond is greatly enhanced with the use of a suitable bonding aid such as an un-filled epoxy resin systems and slurry of Portland cement, plus any latex additives for a Portland cement-based repair system. Precautions should also be takento remove all loose and friable ma-terials from the surfaces to be bonded.④Dimensional StabilityShrinkage of materials during curing should be kept to a minimum. Subsequent dimensional change should be very close in the substrate in order to prevent failure⑤Initial Resistance to Environmentally In-duced DamageSome initial exposure conditions may lead to premature damage lo repairs. For example, partially cured Portland cement repairs can dete-riorate from hot weather preventing full hydration of the cement. To prevent this from happening extra protection during curing time may be nec-essary.⑥Ease of ApplicationMaterials should be easily mixed and ap-plied so that they can be worked readily into small crevices and voids. Ideally, the material should not stick to tools, and should not shear while being trowel led nor slump after placement.⑦AppearanceThe degree to which the repair material should match the existing concrete will depend on the use of the structure and the client' s re-quirements. A surface coating may be required when appearance is important or when cover to reinforcement is small.2. Selection of Repair MethodsA suitable repair counteracts all the defi-ciencies which are relevant to the use of the structure.The selection of tile correct method and material for a particular, application requires careful consideration, whether to meet special requirements for placing strength, durability or other short-or long-term properties. These con-siderations include:1. Nature of the DistressIf alive crack is filled with a rigid material, then either the repair material will eventually fail or some new cracking will occur adjacent to the original crack. Repairs to live cracks must either use flexible materials to accommodate move-ments or else steps must be taken prior to the re-pair to eliminate the movement.2. Position of the CrackTechniques which rely on gravity to intro-duce the material into the crack are more suc-cessfully carried out on horizontal surfaces but are rarely effective on vertical ones.3. EnvironmentIf moisture, water or contaminants are found in the crack, then it is necessary to rectify the leaks Repair to slop leaks may be further com-plicated by the need to make the repairs while the structure is in service and the environment is damp.4. WorkmanshipThe skill the operatives available to carry put the repairs is another relevant factors. Some-times this can mean the difference between a permanent repair and premature failure of the re-pair material.5. CostThe cost of repair materials is usually small compared with the costs of providing access, preparation and actual labor.6. AppearanceThe repair surface may be unsightly, par-ticularly when it appears on a prominent part of the building. In this case, the repair system will include some form of treatment over the entire surface.Reference[1]Philip Jodidio, Contemporary European Architecture, Taschen, Koln, pp.148-153[2]Ann Breen & Dick Rigby, Waterfronts, McGraw-Hill, Inc.

工程造价管理中英文对照外文翻译文献

中英文对照外文翻译(文档含英文原文和中文翻译)The significance of control construction costs manages on entireprocessFirst, The necessary of control construction costs manages on entire process Talk about the management and the control on construction costs, that the field we are just accustomed to is thought of is a project advance in final account. Indeed , right away at present system and reality,what the job of that the management and the control on construction costs is advance in final account. Be that in advance, the people who work on final account according that already be ascertaied of the working drawing to calculate project amounts,apply a quota mechanically, the meter mechanically fetching cost, or designing that according to the drawing sheet and construction organization after construction is over as well as the scene construction visa takes notes weaves the final account being completed. This is necessary , useful no doubt. But we must see that when pre-final accounts personnel weave working drawing budget or the final account being completed, the construction plan and thedesign paper already determined. But construction being to take according to picture as principle, so then in advance, job done by final account personnel is only the change secretly scheming against cost produced by design alteration and prevents upvaluation from calculating boldly. But suppose the project is unreasonable on economy, there is a fault in decision-making; suppose designing a scheme feasible or be not optimum on the technology; the final account personnel can do nothing for sb then in advance. Job of final account personnel does accounts in advance only under just saying system currently in effect, after the event , can only reflect already complete project amounts inactively , can only reflect design and be under construction passively. This evidently is single-faceted , insufficient , we must carry out the entire proceeding supervisory control on the construction costs of building a project.Concrete conditions of union our country, cost of construction manages have problems as follows:1、Be not enough to take investment decision into the stage of construction costs seriously charge indeed.Investment decision is to produce the construction costs headstream, This one stage blow the expense at take up the total investment forehead about 0.5%~3%,but that can have an effect to raise the project benefit of investment. That the project carries out rational choice on construction is that resource carries out direct , the most important optimization deploy means on economy , project benefit of investment affects efficiency and beneficial result to entire national economy. The developed country charges attach importance to control on investment decision stage construction costs,and costs not stinting big capital of money making the studies on the stage of carrying out investment decision energetically, make relatively comparatively accurate construction costs , go along the controlFor a long time, there is the grave phenomenon investing in swelling in engineering construction of our country,bring the limit for a project feeling longer and longer, construction costs is higher and higher. The cause of that is short of the effective basis of the building of earlier stage ascertaining construction costs, only basis the already completed according to the expert , decision-makers draw lessons to estimate the project construction costs. Because a lot of factor effects, the“three surpass " phenomenon very common, there are main cause as follows:(1) personal factor brings about rough estimate lessening(2) equipment composes in reply material price's not working out according to market quotations.(3) construction units bring forward the too high for exceeding a design criterion 2、The design stage of construction costs is not under the control of strictThe design stage is the faucet in that project construction costs controls. After the investment decision is be made rationally , that is the process of plan the technology and organic together economly . Effective control the cost of construction requires strictly and all-round in the enginee designing . Engineering design of current our country also puts move bidding system , fair competition into practice , cost of construction looks on control engineering effective to design stage as one of thestandard choosing main part being hit by the bid unit , cost of construction carries out the administration controlling on the entire proceeding .Our country major part design that the unit carries out thorough analysis lack on construction project technology and economy , big multiple technologies make light of economy in design but at present , design that the personnel is responsible seemingly only to design project mass , are concerned with the construction costs height not very. Optimize a design plan to such an extent as having no way to pass, the first step designs , the rough estimate gets to the effect controlling general cost of construction's establishment. Mass and depth that engineering design pursues etc. is also insufficient , amounts project mistakes in amounts project detailed lists calculates , misses and not calculating, can't arouse increasing by estimating a project momentary, the mass making a tender work is difficult to ensure that , have no way to have an effect to control construction costs asa result also.3、Has not adopt the amounts project detailed list quoted price way being applied or used universally on the international all roundAdopt the amounts project detailed list quoted price way being put into use commonly on the international , is that our country construction costs system reforms and cause the inevitable trend reforming to bid system in invitation to bid tender.One of important act carrying out project public bidding system being to build socialist market economy and to perfect construction market operating mechanism in construction field. After the construction project tender is carried out all round in our country, the effect is obvious in the respect of shortening the mass building a time limit for a project , ensuring a project , reducing construction costs , boycotting an unhealthy tendency. Have ensured the invitation to bid people and bidder's lawful rights and interests also effectively. With the socialist market economy uninterrupted growth,the original tender stage puts the budget quota valuation pattern into practice already doing not adapting , adopt the amounts project detailed list quoted price way being put into use commonly on the international to carry out a tender is an inevitable trend. Ministry of Construction has issued amounts project detailed list valuation method , amounts project detailed list valuation has been in construction project tender job , person has provided project quantity from invitation to bid according to national unification project amounts calculation regulation , quoted price, and classics have judged the reason bidder autonomously trying the at a low price middle bid construction costs valuation pattern.That carrying out amounts project detailed list valuation method is one important measure of item of construction costs deepen the reform, is standard tender behavior effective measure. This method is beneficial to changing over taking that "amounts" ", "price" are "quota-consuming" as dominant static state managing a pattern , make project amounts in detailed list not enter competition, competition being confined to price only; Beneficial to rightness appraises enterprise strength; Project mass beneficial to ensuring that, reduces construction costs; May cut down the physical labour complicated and overloaded repeating the amounts calculating a project; Facilitate the tender quoted price job; Argue with the dispute back and forth in cutting down project settlement; Receive a track step by step with the convention "controllingamounts , guiding price , competing for a fee's on" the international, deepen the reformation that project valuation manages mainly according to the marketplace changes development, taking one's place on the international market for our country contracts business creates condition.4、The stage being under construction controls lack to construction costsWant to have strict control design alteration too in the stage being under construction. Guard the pass though that working drawing appears in joint trial or are able to have all sorts of problems, but call for to design a branch in the process of construction hard to avoid is strict out of the construction works complexity, the situation changing after avoiding doing first, is also that the weight avoiding break a rough estimate , effective control engineering of construction costs cost of construction plays with a link. At the same time, the sharpening contract manages , ensures equality and mutual benefit issuing contract of method and contracting method.5、The construction costs being completed settling a stage's controls a project inefficientlyThat the final account being completed is that entire construction costs is under the control of the most important one is encircled by construction works. How the final account being completed can reflect actual entire project cost of construction honestly , have also reflected the ability issuing contract of method and contracting method to construction costs administration , have finished handling a project in time the final account being completed must collect , arrange settling a data , pursuing , designing the certificate material changing notice , various warning including that the project is completed and so on being completed. These data collecting must pay attention to whose validity with obtaining evidence, specimen seal impression having designing personnel's signature and being related to if the design alteration advice note must be made known to lower levels by plain design organ. Scene inspection and control visa must label seal and the ratification going on a punitive expedition to such that designing a personnel etc. having construction site person in charge of first party. Great majority our country construction projects are completed in the project being under construction when the final account, during the period of the final account being completed contracting method , are are under construction contracting method calculating commonly much in the book being completed winding up an account , are issue contract of haggie just inexhaustible in devices and schemes , are dispute over trifles phenomenon is grave , project settlement drags repeatedly , some confirmation having drug once and , greatly, affecting engineering construction project sigmatism and building construction costs.A construction project includes the following procedure from brewing , planning , designing that to establishing completion and commissioning: Be that the project letter of advice stage , feasibility appraise the stage , design stage , the stage being under construction , acceptance check stage and the queen being completed estimate that.Correspondingly, the construction costs ascertaining that and the project construction phase job look at and appraise the stage adapting to , several being allotted in general for the following: The investment studying stage establishment inthe project letter of advice and feasibility is estimated, design stage establishment designs a rough estimate in the first step, budget designing that the stage weaves working drawing in working drawing, budget builds ampere of construction costs face to face with working drawing for basis tender project engineering contract, price is also that the form ascertains that with the business contract; Project amounts putting stage into practice being going to be completed according to contracting reality in project, takes contract price as basis , considers cost of construction rise aroused by inflation of prices at the same time , considers the project and cost being difficult to estimate that to designing middle but happening in putting stage reality into practice , the example is ascertained estimating price; All-in cost costing in the reality being completed checking and accepting a stage , assembling into engineering construction process middle all round, weaves the final account being completed , embodies the actual cost of construction that a construction project according to the facts."Four guess that two-valence "is interrelated , the former restricts the latter , the latter supplements the former.What is called, build the construction costs administration and control, it is the occurrence contracting the stage and construction in the investment decision stage , design stage , construction project putting stage into practice with construction construction costs to control within the cost of construction quota O. K. , correcting the deviation happening at any time, to ensure that the project manages the target realization , get fairly good benefit of investment and social benefits in an attempt being able to use manpower and material resources, financial resources rationally in building a project one by one.Second, the importance of the investment decision-making stage of project cost controlConstruction projects in the investment decision-making stage, the project of the techno-economic decision-making, as well as the cost of construction projects completed and put into production after the project cost-effective, have a decisive impact on the construction project cost control is an important stage. Project cost management as a decision-making stage in the feasibility study report shall be prepared, and economic evaluation of the proposed project, select the technically feasible and economically the construction of example programs and to optimize the construction program on the basis of the preparation of high-quality items investment is estimated that the project construction so that the real control of the project has played the role of total investment.The impact of the decision-making phase of the project cost are the main factors: a, the determine level of construction standards; b, the choice of built-up areas; c, building location (site) selection; d, project the economic scale; e, technology selection f, equipment selection .Such as the choice of built-up areas, there is a basic principle, that is close to raw materials, fuel and consumer principles. This project completed and put into production, you can avoid the raw materials, fuels, and finished the long-haul transport, reduce costs, lower costs; transportation distance may be shortened to reduce the flow of time, speed up cash flow and is conducive to business. If theproject's economic size, economies of scale, product standard is a reasonable means of production volume, a number of products under certain conditions, was "increasing returns" of economic phenomena, that is, with the expansion of production volume, unit cost reduction, revenue increase.Therefore, in order to phase in the investment decision-making control over project cost effective, we must do a good job in the following areas:(1) the implementation of construction project legal person responsibility system, the construction project from planning to implementation of the whole process of the use of funds and repayment responsibilities to people and projects at the same time establish a system of matching corporate oversight mechanisms, by the competent authorities and supervision of the industry sector establishment of a monitoring group to oversee the use of project funds.(2) to conduct market analysis and seeking truth from facts, to avoid the blindness of the project decision-making, reduce risk and lower investment, give full consideration to construction projects in the future competitiveness of the market so that more scientific book design and reliability(3) Capital financial capital must be committed to a formal document, investment funds must be put in place the parties, there must be a funding document to ensure that projects are implemented on schedule after approval. Conditions of the loans should be carefully analyzed and compared to minimize the interest burden and repayment pressure.(4) Strengthening of engineering geology, hydrogeology, as well as land, water, electricity, transport, environmental protection projects such as the work of the depth of the external conditions, so that there is sufficient basis to estimate the investment. At the same time, extensive research should be to compare similar projects, a serious functional analysis, comparison and choice of multi-program, a full-scale technical feasibility studies and economic evaluation, the finalization of technologically advanced, reliable, economical and rational project construction program in order to estimate more accurate and realistic estimate of the amount of investment in order to make the project cost from the start position in a more reasonable level.Third, the design phase of the importance of project cost controlMake investment decisions in the project, the project cost control is the key to the design. Design is in the technical and economic implementation of the proposed project to conduct a comprehensive arrangement, is also planning the construction process. Technologically advanced, economical and rational design can reduce the project construction period, savings investment, to improve efficiency. According to expert analysis, design fee generally equal to the construction of the project life-cycle cost of less than 1%, which costs less than 1% of project cost accounts for the impact of degrees above 75%. Because of the general construction projects, selection of materials and equipment accounted for more than 50% of the cost of the project, and in the design phase of architectural forms, structural type, the selection of equipment and materials have been identified in the construction of post-implementation phase, the impact of the project cost a small (10 % or less). This shows that the design quality is crucial to the entire projectThe same construction project, the same single unit of work can have different programs, which have different costs, it is therefore necessary to meet the function under the premise of doing a number of options, through technical comparison, economic analysis and efficiency evaluation, selection of technology selection into the application of economic and rational design, that is, the process of design optimization. Often used to optimize the design of the program, also known as the value of value engineering analysis, that is, as far as possible in meeting the functionality or improve the function of the premise, as far as possible to reduce costs.Occurred in the cost of all parts of the application of value engineering, construction investment will require a lot of people, financial, and material, and thus the value of engineering construction works great. For a rather mature and effective management methods, value engineering in a number of works have been widely used in construction.In the engineering design phase correctly handle the technical and economic relationship between the unity of opposites, we can control the key to investment, design and cost management must work closely with staff to make a lot of the technical and economic comparison, in the reduction and control of project efforts, engineering Cost management in the design process should be timely investment analysis on the comparison, the cost of information feedback and dynamic impact on the design, in order to ensure effective control over investment.At the design stage to project cost control should focus on the following aspects.(1) to promote the design and the design of the bidding campaign optimization design approachThe assessment team of experts using scientific methods, in accordance with applicable, economic, aesthetic principles, as well as technologically advanced, well-structured to meet the building energy saving and environmental requirements, a comprehensive assessment of the merits of design, selection of the best in determining the successful program. Estimates of selected investment program in general to be close to the scope of construction projects. The design of these two methods both contract design choice and competition, to ensure selection of the design of technologically advanced, innovative and unique, adaptable, and help control project cost. Design units should strive to improve their own quality, clever engineering design ideas, great care, in order to reduce the project cost more than their brains in order to improve design quality, and strive to put at the design stage in the approval of project cost control within the investment limits.(2) actively pursuing the design limitThe so-called cap design, is in accordance with the approved design of the book and investment is estimated that in the guarantee under the premise of the functional requirements. Preliminary design and budget control, in accordance with the approved budget for the preliminary design and total control of the construction design. Through the ceiling design, every professional, every designer has a target investment limit. During the design process, designers should be more into the program to compare and optimize the design, Not only to ensure that technically advanced and reasonable design, innovative aesthetics, but also the investment limit is not exceededthe target in order to put an end to the design of the project to raise the factor of safety and design standards, or only consider the feasibility of technical solutions, rather than the phenomenon of economic rationality to ensure effective cost control.(3) the implementation of the design of reward and punishment systemIn order to limit the design of the implementation into practice, the limit should be set up and sound system designed to reward and punishment. To limit the design is done well, cost savings and control of investment there is the effectiveness of the project legal person should be given appropriate incentives and design units. Design to limit the development of the internal design of assessment and incentive methods to limit attention to the design, made to save investment and effective cost control offices and the significant achievements of individuals, should be rewarding. Do not attach importance to limit the design, do not take measures to save the investment, resulting in more than a design limit investment offices and individuals should be given to economic penalties. Do reward and encourage designers to design deep potential economic importance to design the control of a reasonable project cost will be a major breakthrough.Fourth、the cost control of the implementation phase of construction project1, the bidding process stageThe implementation of construction project bidding is effective means of construction projects to control the implementation phase of the project cost. If we want To do a good job for bidding, the first we should make sure that qualification is clearance, and resolutely put an end to bribery, such as all the Phenomenon about destruction of all bidding discipline; Secondly, we should strengthen the bid management, to ensure the accuracy and confidentiality of bid preparation; Third, make sure the method of Evaluation and Calibration are Scientific .when select the successful projects as a standard we should concern about the reasonable, short period, reputable companies, construction considerations such as experience. when we evaluation, the first is technical standard assessment, the follow is business assessment,this can ensure open, fair and just.2, the construction phaseIn the construction phase construction ,the goles based on project budget or contract price of Civil works and installation works and project cost control of Civil works and installation works. At this stage the scope for savings has been small, but it is likely to lead to waste,this make us give them adequate attention for the control of project cost.(1) strengthen the technical and economic comparison of construction programConstruction is an important work of the design of constructing orgnization. Reasonable constructing program can shorten the period of constructing, ensure the quality of the project and enhance economic efficiency. Comparing and analysing the constructing program from technical and economic view and comparing the three techno-economic index of the quality, duration and cost through qualitative analysis and quantitative analysis can take good use of manpower, material and financial resources, achieving better economic benefits. Consequently, good construction management is an important way of all-round cost management.(2) a sound system design change Examination and approval systemIf design subject need to be change, we should take action as far as possible in advance, because the sooner the change, the smaller loss; Second, before each design ofchanges we must analysis the quality of project and cost, and this should receive the consent of the original design. If it breakthrough the total project cost estimates after the change, this must be approved by the review of the relevant departments, we should prevent these things happened such as increasing design elements ,improving the design standards, increasing the project cost.(3) check strictly with visa procedures of the project site we should Construct project management system , establish the specialized departments,and through the use of specialized management of professionals for the project, to avoid the phenomenon that project management staff just care visa only, take no concern about the economic accounts, resulting the serious consequences such as investment is out of control.For Seriously changes of visa procedures we should make the building side, supervision side, the construction site together representatives signed a manner to ensure that the authenticity of the visa, the rationality of the economy of changes and to avoid the disputes caused by the phenomenon of fraud.(4) do a good job in the completion of the audit settlement priceClearing refers to the completion of construction enterprises in accordance with the terms of the contract completed by the contractor within the engineering, land quality experience, and in accordance with the contract, the construction units to carry out the final project settlement price. Completion of the project audited settlement is approved in accordance with the construction of the project cost. Therefore, the completion of settlement of the audit is a very important work, should focus on the following:① check the accuracy of the project quantity.the check of project Quantity is the most important and most complicated, the most detailed work in process of the settle of completed project, this must be based on completion of the project plan, changed design and construction of the scene .it strictly in accordance with the provisions of the rules one by one in terms of project review to prevent the units of construction to increase the volume of inflated project cost in the settlement on completion of the project.② examine whether the additional apply is right . check the sub-projects listed in the price in line with the fixed unit price, check whether the name, specification, measurement units and the content consistent with the units of the valuation table; for the unit price of conversion, the first step is to check if the conversion price was fixed allowed, followed check if the conversion price is correct.③ check if the standards for the admission fee In line with the cost of the fixed and the cost of policies and regulations of the project during the construction.Fifth, the thinking and outlook of project cost management system From a long time, we generally ignore the the project cost control of preparatory work for the construction phase, and control projects often focus on the cost of the construction phase - the budget review working drawings and reasonable settlement。

It seeks to address the necessity for applying BIM and re-organising the processes and roles in hospital building projects. This type of project is complex due to complicated functional and technical requirements, decision making involving a large number of stakeholders, and long-term development processes. Design/methodology/approach– Through desk research and referring to the ongoing European research project InPro, the framework for integrated collaboration and the use of BIM are analysed. Through several real cases, the changing roles of clients, architects, and contractors through BIM application are investigated.Findings–One of the main findings is the identification of the main factors for a successful collaboration using BIM, which can be recognised as “POWER”: product information sharing (P),organisational roles synergy (O), work processes coordination (W), environment for teamwork (E), and reference data consolidation (R). Furthermore, it is also found that the implementation of BIM in hospital building projects is still limited due to certain commercial and legal barriers, as well as the fact that integrated collaboration has not yet been embedded in the real estate strategies of healthcare institutions.Originality/value– This paper contributes to the actual discussion in science and practice on the changing roles and processes that are required to develop and operate sustainable buildings with the support of integrated ICT frameworks and tools. It presents the state-of-the-art of European research projects and some of the first real cases of BIM application in hospital building projects. Keywords Europe, Hospitals, The Netherlands, Construction works, Response flexibility, Project planningPaper type General review1. IntroductionHospital building projects, are of key importance, and involve significant investment, and usually take a long-term development period. Hospital building projects are also very complexdue to the complicated requirements regarding hygiene, safety, special equipments, and handling of a large amount of data. The building process is very dynamic and comprises iterative phases and intermediate changes. Many actors with shifting agendas, roles and responsibilities are actively involved, such as: the healthcare institutions, national and local governments, project developers, financial institutions, architects, contractors, advisors, facility managers, and equipment manufacturers and suppliers. Such building projects are very much influenced, by the healthcare policy, which changes rapidly in response to the medical, societal and technological developments, and varies greatly between countries (World Health Organization, 2000). In The Netherlands, for example, the way a building project in the healthcare sector is organised is undergoing a major reform due to a fundamental change in the Dutch health policy that was introduced in 2008.The rapidly changing context posts a need for a building with flexibility over its lifecycle. In order to incorporate life-cycle considerations in the building design, construction technique, and facility management s trategy, a multidisciplinary collaboration is required. Despite the attemptfor establishing integrated collaboration, healthcare building projects still faces serious problemsin practice, such as: budget overrun, delay, and sub-optimal quality in terms of flexibility,end-user’s dissatisfaction, and energy inefficiency. It i s evident that the lack of communicationand coordination between the actors involved in the different phases o f a building project is among the most important reasons behind these problems. The communication between different stakeholders becomes critical, as each stakeholder possesses different set of skills. As a result, the processes for extraction, interpretation, and communication of complex design information from drawings and documents are often time-consuming and difficult. Advanced visualisation technologies, like 4D planning have tremendous potential to increase the communication efficiency and interpretation ability of the project team members. However, their use as an effective communication tool is still limited and not fully explored (Dawood and Sikka, 2008).There are also other barriers in the information transfer and integration, for instance: many existing ICT systems do not support the openness of the data and structure that is prerequisite foran effective collaboration between different building actors or disciplines.Building information modelling (BIM) offers an integrated solution to the previously mentioned problems. Therefore, BIM is increasingly used as an ICT support in complex building projects. An effective multidisciplinary collaboration supported by an optimal use of BIM require changing roles of the clients, architects, and contractors; new contractual relationships; and re-organised collaborative processes. Unfortunately, there are still gaps in the practical knowledge on how to manage the building actors to collaborate effectively in their changing roles, and to develop and utilise BIM as an optimal ICT support of the collaboration.This paper presents a general review of the practical implications of building information modelling (BIM) based on literature review and case studies. In the next sections, based on literature and recent findings from European research project InPro, the framework for integrated collaboration and the use of BIM are analysed. Subsequently, through the observation of two ongoing pilot projects in The Netherlands, the changing roles of clients, architects, and contractors through BIM application are investigated. In conclusion, the critical success factors as well as the main barriers of a successful integrated collaboration using BIM are identified.2. Changing roles through integrated collaboration and life-cycle design approachesA hospital building project involves various actors, roles, and knowledge domains. In The Netherlands, the changing roles of clients, architects, and contractors in hospital building projects are inevitable due the new healthcare policy. Previously under the Healthcare Institutions Act (WTZi), healthcare institutions were required to obtain both a license and a building permit for new construction projects and major renovations. The permit was issued by the Dutch Ministry of Health. The healthcare institutions were then eligible to receive financial support from the government. Since 2008, new legislation on the management o f hospital building projects and real estate has come into force. In this new legislation, a permit for hospital building project under the WTZi is no longer obligatory, nor obtainable (Dutch Ministry of Health, Welfare and Sport, 2008). This change allows more freedom from the state-directed policy, and respectively, allocates more responsibilities to the healthcare organisations to deal with the financing and management of their real estate. The new policy implies that the healthcare institutions are fully responsible to manage and finance their building projects and real estate. The government’s support for the costs of healthcare facilities will no longer be given separately, but will beincluded in the fee for healthcare services. This means that healthcare institutions must earn back their investment on real estate through their services. This new policy intends to stimulate sustainable innovations in the design, procurement and management of healthcare buildings, which will contribute to effective and efficient primary healthcare services.The new strategy for building projects and real estate management endorses an integrated collaboration approach. In order to assure the sustainability during construction, use, and maintenance, the end-users, facility managers, contractors and specialist c ontractors need to be involved in the planning and design processes. The implications of the new strategy are reflected in the changing roles of the building actors and in the new procurement method.In the traditional procurement method, the design, and its details, are developed by the architect, and design engineers. Then, the client (the healthcare institution) sends an application to the Ministry of Health to obtain an approval on the building permit and the financial support from the government. Following this, a contractor is selected through a tender process that emphasises the search for the lowest-price bidder. During the construction period, changes often take place due to constructability problems of the design and new requirements from the client. Because of the high level of technical complexity, and moreover, decision-making complexities, the whole process from initiation until delivery of a hospital building project can take up to ten years time. After the delivery, the healthcare institution is fully in charge of the operation of the facilities. Redesigns and changes also take place in the use phase to cope with new functions and developments in the medical world (van Reedt Dortland, 2009).The integrated procurement pictures a new contractual relationship between the parties involved in a building project. Instead of a relationship between the client and architect for design, and the client and contractor for construction, in an integrated procurement the client only holds a contractual relationship with the main party that is responsible for both design and construction ( Joint Contracts Tribunal, 2007). The traditional borders between tasks and occupational groups become blurred since architects, consulting firms, contractors, subcontractors, and suppliers all stand on the supply side in the building process while the client on the demand side. Such configuration puts the architect, engineer and contractor in a very different position that influences not only their roles, but also their responsibilities, tasks and communication with the client, the users, the team and other stakeholders.The transition from traditional to integrated procurement method requires a shift of mindsetof the parties on both the demand and supply sides. It is essential for the client and contractor tohave a fair and open collaboration in which both can optimally use their competencies. Thed strategy effectiveness of integrated collaboration is also determined by the client’s capacity to organize innovative tendering procedures (Sebastian et al., 2009).A new challenge emerges in case of positioning an architect in a partnership with the contractor instead of with the client. In case of the architect enters a partnership with the contractor, an important issues is how to ensure the realisation of the architectural values as wellas innovative engineering through an efficient construction process. In another case, the architectsory role instead of being the designer. In this case,can stand at the client’s side in a strategic advithe architect’s responsibility is translating client’s requirements and wishes into the ar values to be included in the design specification, and evaluating the contractor’s p this. In any of this new role, the architect holds the responsibilities as stakeholder interest facilitator, custodian of customer value and custodian of design models.The transition from traditional to integrated procurement method also brings consequencesin the payment schemes. In the traditional building process, the honorarium for the architect isusually based on a percentage of the project costs; this may simply mean that the more expensivethe building is, the higher the honorarium will be. The engineer receives the honorarium based onthe complexity of the design and the intensity of the assignment. A highly complex building,which takes a number of redesigns, is usually favourable for the engineers in terms of honorarium.A traditional contractor usually receives the commission based on the tender to construct thebuilding at the lowest price by meeting the minimum specifications given by the client. Extrawork due to modifications is charged separately to the client. After the delivery, the contractor isno longer responsible for the long-term use of the building. In the traditional procurement method,all risks are placed with the client.In integrated procurement method, the payment is based on the achieved building performance; thus, the payment is non-adversarial. Since the architect, engineer and contractorhave a wider responsibility on the quality of the design and the building, the payment is linked toa measurement system of the functional and technical performance of the building over a certainperiod of time. The honorarium becomes an incentive to achieve the optimal quality. If thebuilding actors succeed to deliver a higher added-value that exceed the minimum client’sextra gain. The level of requirements, they will receive a bonus in accordance t o the client’stransparency is also improved. Open book accounting is an excellent instrument provided that the stakeholders agree on the information to be shared and to its level of detail (InPro, 2009).Next to the adoption of integrated procurement method, the new real estate strategy for hospital building projects addresses a n innovative product development and life-cycle design approaches. A sustainable business case for the investment and exploitation of hospital buildings relies on dynamic life-cycle management that includes considerations and analysis of the market development over time next to the building life-cycle costs (investment/initial cost, operational cost, and logistic cost). Compared to the conventional life-cycle costing method, the dynamiclife-cycle management encompasses a shift from focusing only on minimizing the costs to focusing on maximizing the total benefit that can be gained. One of the determining factors for a successful implementation of dynamic life-cycle management is the sustainable design of the building and building components, which means that the design carries sufficient flexibility to accommodate possible changes in the long term (Prins, 1992).Designing based on the principles of life-cycle management affects the role of the architect,as he needs to be well informed about the usage scenarios and related financial arrangements, the changing social and physical environments, and new technologies. Design needs to integrate people activities and business strategies over time. In this context, the architect is required to align the design strategies with the organisational, local and global policies on finance, business operations, health and safety, environment, etc. (Sebastian et al., 2009).The combination of process and product innovation, and the changing roles of the building actors can be accommodated by integrated project delivery or IPD (AIA California Council, 2007). IPD is an approach that integrates people, systems, business structures and practices into a process that collaboratively harnesses the talents and insights of all participants to reduce waste and optimize efficiency through all phases of design, fabrication and construction. IPD principles can be applied to a variety of contractual arrangements. IPD teams will usually include members well beyond the basic triad of client, architect, and contractor. At a minimum, though, an Integrated Project should include a tight collaboration between the client, the architect, and the main contractor ultimately responsible for construction of the project, from the early design untilthe project handover. The key to a successful IPD is assembling a team that is committed to collaborative processes and is capable of working together effectively. IPD is built on collaboration. As a result, it can only be successful if the participants share and apply commonvalues and goals.3. Changing roles through BIM applicationBuilding information model (BIM) comprises ICT frameworks and tools that can support theintegrated collaboration based on life-cycle design approach. BIM is a digital representation ofphysical and functional characteristics of a facility. As such it serves as a shared knowledgeresource for information about a facility forming a reliable basis for decisions during its lifecyclefrom inception onward (National Institute of Building Sciences NIBS, 2007). BIM facilitates timeand place independent collaborative working. A basic premise of BIM is collaboration bydifferent stakeholders at different phases of the life cycle of a facility to insert, extract, update ormodify information in the BIM to support and reflect the roles of that stakeholder. BIM in itsultimate form, as a shared digital representation founded on open standards for interoperability,can become a virtual information model to be handed from the design team to the contractor and subcontractors and then to the client (Sebastian et al., 2009).BIM is not the same as the earlier known computer aided design (CAD). BIM goes furtherthan an application to generate digital (2D or 3D) drawings (Bratton, 2009). BIM is an integratedmodel in which all process and product information is combined, stored, elaborated, and interactively distributed to all relevant building actors. As a central model for all involved actorsthroughout the project lifecycle, BIM develops and evolves as the project progresses. Using BIM,the proposed design and engineering solutions can be measured against the client’s re and expected building performance. The functionalities of BIM to support the design processextend to multidimensional (nD), including: three-dimensional visualisation and detailing, clashdetection, material schedule, planning, cost estimate, production and logistic information, andas-built documents. During the construction process, BIM can support the communicationbetween the building site, the factory and the design office– which is crucial for an effective andefficient prefabrication and assembly processes as well as to prevent or solve problems related to unforeseen errors or modifications. When the building is in use, BIM can be used in combinationwith the intelligent building systems to provide and maintain up-to-date information of thebuilding performance, including the life-cycle cost.To unleash the full potential of more efficient information exchange in the AEC/FM industry in collaborative working using BIM, both high quality open international standards and high quality implementations of these standards must be in place. The IFC open standard is generally agreed to be of high quality and is widely implemented in software. Unfortunately, the certification process allows poor quality implementations to be certified and essentially renders the certified software useless for any practical usage with IFC. IFC compliant BIM is actually used less than manual drafting for architects and contractors, and show about the same usage for engineers. A recent survey shows that CAD (as a closed-system) is still the major form of technique used in design work (over 60 per cent) while BIM is used in around 20 percent of projects for architects and in around 10 per cent of projects for engineers and contractors (Kiviniemi et al., 2008).The application of BIM to support an optimal cross-disciplinary and cross-phase collaboration opens a new dimension in the roles and relationships between the building actors. Several most relevant issues are: the new role of a model manager; the agreement on the access right and Intellectual Property Right (IPR); the liability and payment arrangement according tothe type of contract and in relation to the integrated procurement; and the use of open international standards.Collaborative working using BIM demands a new expert role of a model manager who possesses ICT as well as construction process know-how (InPro, 2009). The model manager deals with the system as well as with the actors. He provides and maintains technological solutions required for BIM functionalities, manages the information flow, and improves the ICT skills of the stakeholders. The model manager does not take decisions on design and engineering solutions, nor the organisational processes, b ut his roles in the chain of decision making are focused on:the development of BIM, the definition of the structure and detail level of the model, and the deployment of relevant BIM tools, such as for models checking, merging, and clash detections;the contribution to collaboration methods, especially decision making and communication protocols, task planning, and risk management;and the management of information, in terms of data flow and storage, identification ofcommunication errors, and decision or process (re-)tracking.way Regarding the legal and organisational issues, one of the actual questions is: “does the intellectual property right (IPR) in collaborative working using BIM differ from the IPRin a traditional teamwork?”. In terms of combined work, the IPR of each element is attached to its creator. Although it seems to be a fully integrated design, BIM actually resulted from a combination of works/elements; for instance: the outline of the building design, is created by the architect, the design for the electrical system, is created by the electrical contractor, etc. Thus, incase of BIM as a combined work, the IPR is similar to traditional teamwork. Working with BIMwith authorship registration functionalities may actually make it easier to keep track of theIPR(Chao-Duivis, 2009).How does collaborative working, using BIM, effect the contractual relationship? On the onehand, collaborative working using BIM does not necessarily change the liability position in thecontract nor does it obligate an alliance contract. The General Principles of BIM Addendum confirms: ‘This does not effectuate or require a restructuring of contractual relationships orshifting of risks between or among the Project Participants other than as specifically required per(ConsensusDOCS, 2008). On the other hand,the Protocol Addendum and its Attachments’ changes in terms of payment schemes can be anticipated. Collaborative processes using BIM willlead to the shifting of activities from to the early design phase. Much, if not all, activities in thedetailed engineering and specification phase will be done in the earlier phases. It means thatsignificant payment for the engineering phase, which may count up to 40 per cent of the designcost, can no longer be expected. As engineering work is done concurrently with the design, a new proportion of the payment in the early design phase is necessary(Chao-Duivis, 2009).4. Review of ongoing hospital building projects using BIMIn The Netherlands, the changing roles in hospital building projects are part of the strategy,which aims at achieving a sustainable real estate in response to the changing healthcare policy.Referring to literature and previous research, the main factors that influence the success of thechanging roles can be concluded as: the implementation of an integrated procurement method anda life-cycle design approach for a sustainable collaborative process; the agreement on the BIMstructure and the intellectual rights; and the integration of the role of a model manager. Thepreceding sections have discussed t he conceptual thinking on how to deal with these factors effectively. This current section observes two actual projects and compares the actual practice with the conceptual view respectively.The main issues, which are observed in the case studies, are:the selected procurement method and the roles of the involved parties within this method;the implementation of the life-cycle design approach;the type, structure, and functionalities of BIM used in the project;the openness in data sharing and transfer of the model, and the intended use of BIM in the future; andthe roles and tasks of the model manager.The pilot experience of hospital building projects using BIM in the Netherlands can be observed at University Medical Centre St Radboud (further referred as UMC) and Maxima Medical Centre (further referred as MMC). At UMC, the new building project for the Faculty of Dentistry in the city of Nijmegen has been dedicated as a BIM pilot project. At MMC, BIM is used in designing new buildings for Medical Simulation and Mother-and-Child Centre in the city of Veldhoven.The first case is a project at the University Medical Centre (UMC) St Radboud. UMC is more than just a hospital. UMC combines medical services, education and research. More than 8500 staff and 3000 students work at UMC. As a part of the innovative real estate strategy, UMC has considered to use BIM for its building projects. The new development of the Faculty of Dentistry and the surrounding buildings on the Kapittelweg in Nijmegen has been chosen as a pilot project to gather practical knowledge and experience on collaborative processes with BIM support.The main ambition to be achieved through the use of BIM in the building projects at UMC can be summarised as follows:using 3D visualisation to enhance the coordination and communication among the building actors, and the user participation in design;facilitating optimal information accessibility and exchange for a highconsistency of the drawings and documents across disciplines and phases;integrating the architectural design with structural analysis, energy analysis, cost estimation,and planning;interactively evaluating the design solutions against the programme of requirements and specifications;reducing redesign/remake costs through clash detection during the design process; andoptimising the management o f the facility through the registration of medical installations and equipments, fixed and flexible furniture, product and output specifications, and operational data.The second case is a project at the Maxima Medical Centre (MMC). MMC is a large hospital resulted from a merger between the Diaconessenhuis in Eindhoven and St Joseph Hospital in Veldhoven. Annually the 3,400 staff of MMC provides medical services to more than 450,000 visitors and patients. A large-scaled extension project of the hospital in Veldhoven is a part of its real estate strategy. A medical simulation centre and a women-and-children medical centre are among the most important new facilities within this extension project. The design has been developed using 3D modelling with several functionalities of BIM.The findings from both cases and the analysis are as follows. Both UMC and MMC optedfor a traditional procurement method in which the client directly contracted an architect, a structural engineer, and a mechanical, electrical and plumbing (MEP) consultant in the design team. Once the design and detailed specifications are finished, a tender procedure will follow to select a contractor. Despite the choice for this traditional method, many attempts have been made for a closer and more effective multidisciplinary collaboration. UMC dedicated a relatively long preparation phase with the architect, structural engineer and MEP consultant before the design commenced. This preparation phase was aimed at creating a common vision on the optimal way for collaboration using BIM as an ICT support. Some results of this preparation phase are: a document that defines the common ambition for the project and the collaborative working process and a semi-formal agreement that states the commitment of the building actors for collaboration. Other than UMC, MMC selected an architecture firm with an in-house engineering department. Thus, the collaboration between the architect and structural engineer can take place within the same firm using the same software application.Regarding the life-cycle design approach, the main attention is given on life-cycle costs, maintenance needs, and facility management. U sing BIM, both hospitals intend to get a much。

外文文献:Project portfolio management –There’s more to it thanwhat management enactsAbstractAlthough companies manage project portfolios concordantly with project portfolio theory, they may experience problems in the form of delayed projects, resource struggles, stress, and a lack of overview. Based on a research project compromised of 128 in-depth interviews in 30 companies, we propose that a key reason why companies do not do well in relation to project portfolio management (PPM) is that PPM often only covers a subset of on-going projects, while projects that are not subject to PPM tie up resources that initially were dedicated to PPM projects. We address and discuss the dilemma of wanting to include all projects in PPM, and aiming at keeping the resource and cognitive burden of doing PPM at a reasonable level.Keywords:Managing programmes,Managing projects,Organisation resources,Strategy1.IntroductionAt any given point in time, most companies engage in many projects. Some of these projects may relate to product development and marketing, others relate to changes in work processes and production flows, while yet others relate to competency development, strategic turns, the implementation of new IT systems, environmental issues etc.A key managerial task is to dedicate resources across all of these projects (as well as do daily work) and consequently,management across projects (project portfolio management (PPM)) is critical to company performance.This paper is based on a large-scale qualitative study,which shows that many project-oriented companies do not perform well when it comes to PPM. This relates to the inability to accomplish projects that are initiated. In particular, we identify the following problems:(1) Projects are not completed according to plan (or they even peter out during their project life cycle);(2) Management and employees feel they lack a broad overview of on-going projects (especially when the number of on-going projects increases as more and more projects are not completedaccording to plan);(3)People experience stress as resources are continuously reallocated across projects in order to make ends meet.These observations are especially interesting because the companies were included in the research project because they were supposed to be especially,experienced in PPM, and because they actually engage in PPM according to the extant body of literature on PPM. For example, part of the companies‘ PPM included an effort to pick the best projects on the basis of explicit or implicit criteria, and an effort to allocate sufficient resources to these projects.However, despite efforts,to practice ‗good‘ PPM, these companies experience severe problems in relation to PPM – especially in letting enough resources go into the ‗right‘ pr ojects. The purpose of this paper is to confront PPM as advocated by normative theories with actual PPM practices. Hence, the purpose is to confront PPM theories with PPM as perceived by managers and other employees for whom PPM is part of, or affects, their work conditions.However, in this paper, we are more interested in PPM as enacted by companies than in universally true perceptions. Hence, we adhere to Weick‘s [1–3] notion of enactment as the preconceptions that are used to set aside a portion of the field of experience for further attention. In regard to PPM, enacted projects are thus the ones management sets aside for further attention (i.e. PPM). As such, we focus especially on ways actors define or enact projects [4] and make sense of how to manage the sum of the projects. Drawing on this perspective, we account for findings that suggest why companies that do engage in PPM still experience problems.2. Project portfolio theoryThis paper draws on Archer and Ghasemzadeh‘s [5, p.208] definition of p roject portfolios as ‗‗a group of projects that are carried out under the sponsorship and/or management of a particular organization‘‘. Henceforth, we define PPM as the managerial activities that relate to(1) the initial screening, selection and prioritisation of project proposals,(2) the concurrent reprioritisation of projects in the portfolio,(3) the allocation and reallocation of resources to projects according to priority.For quite some time researchers have suggested that low completion rates for new product development (NPD) projects and new product failure relate to resource deficiencies in key areas [6,7]. Furthermore, while a host of researchers [8–10] have focused on the dimension of PPM that concernsprocesses relating to selection of projects to be included in the portfolio, research e.g. [11] also increasingly focuses on the day-today management of the project portfolio.3. MethodologyOver a period of two years, we did empirical research on how companies manage their entire range of projects, e.g. renewal projects, strategic projects, IT projects, departmentally specific projects, and production based projects. In relation to the selection of companies to be included in the empirical study, a key criterion was that the study should cover a wide variety of industries. As a result, the empirical study covers 30 companies from industries as diverse as, e.g. mobile telephone communications, finances, energy, pharmaceuticals, toys, software, and foods.However, due to the fact that we were looking for companies, where the amount of on-going projects suggested they were engaged in PPM, the study is biased towards larger companies as well as companies that define at least a substantial part of their activities as projects. The degree to which the companies participated in the study varies. Hence, half of the companies are labelled ‗inner circle‘ companies due to the fact that we drew extensively on these 15 companies. For example, in these companies more interviews were conducted at various points in time and at various organizational levels. Hence, a longitudinal perspective characterizes the involvement of these companies.The remaining half of the companies are labelled ‗outer circle‘ companies because their participation in the study has included fewer top-management interviews, the purpose of which was to gain insight into ways in which (top) management defines the content of their project portfolios and manages them.4. Managerial implicationsA key finding is that the gap between required and available resources is very much attributable to the existence of a host of smaller projects that never become part of enacted project portfolios. Thus, at an aggregated level, the empirical study suggests smaller, un-enacted projects qualify as resources crunchers in so far they are not considered to be a part of enacted project portfolios. In order to overcome this crunch in resources, two solutions seem obvious:(1) Enacting more, i.e. having PPM embrace all projects.(2) Allocating more resources to a pool of loosely-controlled resources for the un-enacted projects to draw on.5. Research implicationsThe empirical study elaborates on the ‗‗significant shortage of resources devoted to NPD‘‘ that Cooper and Edgett argue is the fundamental problem ‗‗that p lagues most firms‘ product development efforts‘‘.Our work especially suggests that the shortage of resources devoted to enacted projects is not a problem that primarily arises in relation to top management‘s PPM. On the contrary, in-good-faith top management dedicates resources to enacted projects on the basis of sound PPM. However, what top managers do not do is take into account the host of smaller projects that individuals initiate and – more importantly – top managers ignore (or at least heavily under-estimate) the amount of resources that these smaller projects tie up. Hence, we argue that especially the crunch in resources may be attributable to the un-enacted competition for resources that smaller projects subject enacted projects to.Consequently, the key contribution of our empirical work to research is that it emphasises that if we wish to study PPM (and especially if we wish to relate PPM to project performance), we might be better off taking into account the entire range of projects that actual (not enacted) portfolios are comprised of. Thus, if we as researchers only enact the projects that are neatly listed by top management, then our research will neglect the host of projects that are not subject to PPM, projects that nonetheless take up valuable, and scarce, resources.The fact that the empirical study includes interviews with managers, i.e. those who do PPM, and interviews with personnel at lower organisational levels, i.e. those whose work is subject to PPM, is the reason why we were able to identify un-enacted projects. Thus, researchers interested in PPM should be careful not to rely too heavily on a management perspective.6. Conclusion and limitationsThe main conclusion is that as long as some projects are un-enacted, companies may experience a drain on resources that reduces the time and resources actually devoted to projects subject to PPM. Hence, each individual company should decide whether or not all projects should be part of PPM and if the end result of such a decision is not to make comprehensive project lists (i.e. lists that include all minor projects), then management should decide how many resources should be set aside for the plethora of small projects that do not appear on the project list.One way in which the crunch in resources can be reduced is by ensuring that smaller projects do not take up a critical portion of the resources that are – officially – set aside for the completion ofprojects subject to PPM. However, due to the exploratory nature of the study accounted for in this paper, our findings relate far more to what companies actually do (positive theory in Hunt‘s terms), rather than to what they ought to do (normative theory in Hunt‘s terms). Although generating positive theory is indeed a crucial first step – especially in relation to the future of PPM theory –positive theory cannot, and should not, stand alone. Hence, the key challenges for PPM theory in the future are to produce normative theory that offers sound suggestions as to how companies can improve their PPM.Another limitation of our study is that the empirical part was carried out in a Danish context as the 30 companies involved are located in Denmark, which may not be sufficiently representative for companies worldwide because Denmark has, to a larger extent, a bottom-up culture. Therefore, the portion of smaller un-enacted projects may be bigger here than in companies in other countries. We hope that our study will inspire other researchers to carry our similar studies in other countries.References[1] Aboloafia MY, Killduff D.

指导教师评语: 签字:年月日Defining Risk Response PlansYou’ve identified your risks, analyzed them for their impacts onthe project, assigned probabilities and impact values, determined an expected value, and ranked them in order. You’ve also determined which of the risks, given all those conditions, require response plans. This chapter discusses what risk response plans are, the techniques for developing response plans, and how to document and write plans for those risks that have a high probability and high impact on the project.Let’s get to it.Risk Response PlanningRisk Response Planning is the process of deciding what actions to take to educe threats (especially to schedule and cost) while taking advantage of he opportunities other risks present.Typically, you’ll want to develop risk response plans for riskswith the potential for high probability and high impact. It isn’t efficient to spent time writing response plans for risks you’ve determined aren’t likely to occur and won’t impact the project significantly if they do. For example, if I’m building a tourist center in the Mojave Desert, I wouldn’t spend time on a risk response plan for the possibility of rain(It does rainin the Mojave an average of 2.5 inches per year), so the possibility exists, but it’s highly unlikely it would impact my project. I’ll deal with thesetypes of risks in the “Contingency Planning” section a littlelater in this chapter.Remember that risk management planning, including thedevelopment of risk response plans, isn’t a one-time exercise. As youprogress through the project and learn more about potential risk events, you’ll reevaluate their impacts, which may require a change in strategy to deal with the risk and a new or revised response plan. And even though I’ve focused primarily on risks that prevent you from meeting the goals of the project, don’t forget that risks can produce opportunities.Uncertain CertaintyOne thing is certain: your project does have risks, and if youchoose to ignore them, your project will have an uncertain outcome. All project risk is closely linked with the availability of information and communication, or the lack thereof, as I’ve talked about previously. Themore information you have, the more likely you’re able to predictthe risk event and its impacts.And the better you’re able to predict risk imp acts, the betteryou’ll be at creating risk response plans.When thinking about risk response plans, keep in mind that risk out-comes generally fall into three categories:* Known risks with predictable outcomes* Known risks with uncertain outcomes* Unknown risks with unpredictable outcomesThese are fairly straightforward. A known risk is something you know has the potential to happen. The term predictable outcomes implies you know with reasonable certainty what the impacts and outcomes of the risk events would be if they occurred. Unpredictable outcomes are impacts and consequences of the risk event that aren’t fully identified or known. Let’s use a simple example to explain each of these outcomes. You’ve decided to paint your garage door this week end. One risk that could keep you from completing this project is the weather. No problem—you cruise the Internet and check out the local forecast, which predictsclear and sunny skies, with little possibility of showers. You have the means to learn about the weather (the Internet site) and to determine the certainty of the impact (a 10 percent chance of showers). That means you know, with predictable certainty, that this risk has a low chance of occurring. Known risks with uncertain outcomes are more difficult because, well, their outcomes aren’t certain. However, the amount of uncertainty could vary. You may, for example, know it’s going to rain but not know when it’ll start or how long it’ll continue. When you’re facing project risks with uncertain outcomes, I recommend learning everything you can about the risk and its possible impacts. (Since the impacts are unpredictable, this isn’t always possible.) You should interviewstakeholders, research past projects, and try to move as far fromtheuncertainty end of the spectrum as you can. The more you know, the better.The last bullet listed previously, unknown risks with unpredictable out- comes, says you don’t know about the risk and you don’t know about its impacts. It’s an unknown risk with an unknown o utcome. Suppose you’re happily painting away and are three-quarters finished when a flock of geese happens to fly right over your house. You guessed it. An unknown risk with an unpredictable outcome has occurred.Many project decisions are made without benefit of knowing all the facts, and risk analysis is no exception. Risk, after all, is primarilyabout uncertainty. Analyzing the risks tells you about the possible outcomes for the risk, and the response plan addresses how to deal with those outcomes.The greater your certainty of the outcome, the easier it will be to develop response plans. For example, if you know rain is a certainty on the day you’re planning on painting the garage, you can devise response plans that are fairly precise. You could postpone the painting to another day and sweep the garage floor instead.Or, perhaps you know with reasonable certainty that the rain is coming but won’t start until early afternoon. In that case, you could quickly paint the door in the morning while the sun is still out (or the clouds are rolling in) and then flip open the door so it’s protected by thegarage ceiling until it dries.Purpose of Planning for RisksThe purpose for risk planning is to determine the most appropriate response to reduce, control, or take advantage of the risk event. Along with determining the response, you’ll want to make certain you’re choosing the right strategy for the risk event. After determining the strategy to use, you’ll develop an action plan to put this strategyinto play should the risk event occur.The second purpose for risk planning is to determine a risk owner. I talked about risk owners and their responsibility in Chapter 2, “Identifying and Documenting Risks.” Once the plan is developed, therisk owner is the one held accountable for watching for risk triggers, tracking the risk, recommending the implementation of the response plan if the situation war-rants it, and then monitoring the effectiveness of the response plan once it’s implemented.Risk response planning also has an added benefit. When risk eventsdo occur, you’ll be able to remain calm, cool, and levelheaded about whatto do.Rather than reacting like our friend Ned, you’ll calmly reach for theresponse plan document and know what to do. When you’re i n panic mode, the object is to resolve the problem as quickly as possible. That means you usually deal with things the quickest and easiest way you can think of just to get everything under control. But getting immediate control doesn’t necessarily solve the problem in the long run. Response planning allows you determine the best method for dealing with a risk, which gives you a higher probability of meeting your project goals. Risk Response TechniquesYou have several strategies for dealing with risk that help reduceor control the impacts of risk events. The most common strategies are as follows:* Avoidance* Transference * Mitigation* Acceptance* Contingency planning* Independent verification and validationEach of these techniques has its strengths and weaknesses. Before determining which strategy to use, make certain you understand the type of risk you’re dealing with, as well as the severity of the risk. You’ll want to choose the strategy that will be the most effective and cost efficient for dealing with the risk event. If it costs you more to respond to the risk than the consequences of the risk itself, you may want to consider a different strategy.AvoidanceYou may have already guessed that the risk avoidance technique is about avoiding risk. True. It encompasses more than that, however. Risk avoidance techniques include the following:* Avoiding the risk altogether* Eliminating the cause of the risk event* Changing the project plan to protect the objectives from the risk eventLe t’s look at some examples for each technique. Avoiding the risk altogether implies that you know the outcomes of the risk with relative certainty and can take steps to keep the risk event from occurring. Suppose Ned and the photo-shoot team are headed to the airport to catch their flight to Paris. In keeping with Ned’s usual manner, he has held everyone up to the last second. If they leave any later, they won’t havetime to check the million pieces of luggage Ned is bringing and get through security in time to catch the flight. Sherry, the quick-thinking project manager, decides to do a traffic check before leaving. She logs onto the Internet and finds there’s been a major accident on the highwaythey were planning on taking to the airport. To avoid delays andkeep them from missing the flight, Sherry decides on an alternate route that bypasses the accident and avoids the risk event.Eliminating the cause of the risk is a technique that workssomething like this. Sherry knows that the team’s luggage looks like every other piece of luggage they’re likely to see on an airport conveyor belt. Theteam is carrying some sensitive company information and a few pieces of specialized equipment. Sherry can eliminate the cause of this risk by carrying the company material and specialized equipment on board intheir carry ones.One of the objectives of the photo assignment is to shoot picturesof Parisians doing everyday tasks—strolling through the park, eating at side-walk cafés, shopping, and so on—outside in the open air. Arainstorm pops up on the day this shoot is supposed to occur. Sherry changes the project plan by switching an indoor shooting day with the outdoor shooting day to protect the project objectives from the risk event.Avoidance is a great strategy when you can use it. The trouble is it isn’t appropriate for every risk, so let’s look at some more techniques.定义风险应对计划你已经定义风险,分析了他们对项目的影响、分配的可能性和有影响的标准,决定期望中的标准,并且把他们按目的排列整齐。
