Periodic re-examination of these goals and standards is warranted.Co nstruction costs are not “high〞or “low〞in the abstract, but rather in relation to specific quality standards and the design solutions, means, and methods used to attain these standards. Thus, evaluating whether construction costs are appropriate involves: • first, determining whether quality standards are excessive, insufficient, or appropriate;• second, determining whether resultant project costs are reasonable pared to projects with essentially the same quality parameters.“Quality〞enpasses the durability of building systems and finishes; the robustness and life-cycle performance of building systems; the aesthetics of materials, their position, and their detailing; and the resource-sustainability and efficiency of the building as an overall system.Overall Goals and Quality StandardsUC Irvine, in order to support distinguished research and academic programs, builds facilities of high quality. As such, UC Irvine’s facilities aim to convey the “look and feel,〞as well as embody the inherent construction quality, of the best facilities of other UC campuses, leading public universities, and other research institutions with whom we pete for faculty, students, sponsored research, and general reputation.Since 1992, new buildings have been designed to achieve these five broad goals:1. New bu ildings must “create a place,〞rather than constitute stand-alone structures, forming social, aesthetic, contextually-sensitive relationships with neighboring buildings and the larger campus.2. New buildings reinforce a consistent design framework of classical contextual architecture, applied in ways that convey a feeling of permanence and quality and interpreted in ways that meet the contemporary and changing needs of a modern research university.3. New buildings employ materials, systems, and design features that will avoid the expense of major maintenance (defined as >1 percent of value)for twenty years.4. New buildings apply “sustainability〞principles -- notably, outperforming Title 24 (California’s energy code) by at least 20 percent.5. Capital construction projects are designed and delivered within theapproved project budget, scope, and schedule.UC Irvine’s goals for sustainable materials and energy performance were adopted partly for environmental reasons, and partly to reverse substantial operating budget deficits. The latter problems included a multi-million dollar utilities deficit that was growingrapidly in the early ‘90s, and millions of dollars of unfunded major maintenance that was emerging prematurely in buildings only 10-20 years old. Without the quality and performance standards adopted in 1992, utilities deficits and unfunded major maintenance costs would have exceeded $20 million during the past decade, and these costs would still be rising out-of-control.UC Irvine’s materials standards, building systems standards, sustainability and energy efficiency criteria, and site improvements all add cost increments that can only be afforded through aggressive cost management. Institutions that cannot manage capital costs tend to build projects that consume excessive energy, that cost a lot to maintain, that suffer premature major maintenance costs, and that require high costs to modify. Such problems tend to pound and spiral downward into increasingly costly consequences.Every administrator with facilities experience understands this dynamic. Without effective construction cost management, quality would suffer and UC Irvine would experience all of these problems.The balance of this document outlines in greater detail the building performance criteria and quality standards generally stated above, organized according to building systems ponent classes. Each section discusses key cost-drivers, cost-control strategies, and important cost trade-offs. Design practices cited are consistently applied (although some fall short of hard and fast “rules〞).Building Organization and MassingConstruction cost management starts with the fundamentals of building organization andmassing. UC Irvine’s new structures’ floor plates tend to have length-to-width ratios<1.5, to avoid triggering disproportionate costs of external cladding, circulation, and horizontal mechanical distribution. Our new buildings tend to be at least three floors high -- taller if floor plate areas do not dip below a cost-effective threshold, and generally taller in the case of non-laboratory buildings (but not so tall that a high-rise cost penalty is incurred). Other design ratios are observed, such as exterior cladding area/floor area <0.5, and roof+foundation area/floor area <0.4.Architectural articulation is generally achieved through textured or enriched materials,integral material detailing (such as concrete reveal patterning), and applied detailing (e.g.,2window frames and sills), particularly at the building base. Large-scale articulation is concentrated at the roofline (e.g., shaped roof forms) and at the pedestrian level (e.g.,arcades), where it will “create the biggest bang for the buck,〞rather than through modulating the building form, itself. This is more than a subtle design philosophy, as the cost impact is substantial.Lab buildings pleted in the past decade separate laboratory and non-laboratory functions into distinct, adjoined structures (although such a building may look like one structure). Consolidated non-laboratory functions include faculty, departmental, staff,post-doc, and graduate student offices; restrooms; circulation (elevators, lobbies, primary stairways); classrooms, seminar rooms, conference rooms, and social areas designed tofoster interaction and to provide a safe area for eating and drinking; dry labs and dry lab support functions; and general administrative support.Consolidating these functions into a separate structure provides considerable cost savings:lower-cost HVAC (heating/ventilation/air-conditioning) system, wider column spacing, lower floor stiffness (less stringent vibration criterion), lower floor-loading,fewer fire-control features and other code requirements, steel-framed or steel/concrete hybrid structural system with concrete flat-slab flooring system, smaller footings, and(typically) curtain wall fenestration. This approach usually enables offices to have operable windows.This two-building approach can be seen clearly at Gillespie Neurosciences Building, the Sprague Building, Hewitt Hall, and the UCI Medical Center Health Sciences Laboratory,where consolidating and separating non-laboratory functions saved 7-10 percent in overall construction costs and 15 percent/year in energy expense. (The non-laboratory building incurs a small fraction of the energy expense of the laboratory block.)A set of design strategies, applied in bination, has proven effective in controlling the cost of laboratories:• Utilizing a consistent lab module• Utilizing a reasonable vibration criterion and locating ultra-sensitive conditions at-grade or employing benchtop vibration isolation• Using 22 ft. X 22 ft. column-spacing• Concentrating fume hoods and utility risers into a central “wet zone,〞thus limiting horizontal mechanical distribution• Concentrating laboratory support areas into the central core of a laboratory structure, where utilities are available but daylight is not needed, thus enablinglab structures to be 110-132 feet wide• Utilizing dual-usage circulation/equipment cross-corridors through this central lab support zone, with sufficient width (typically 11 feet) to line the corridors with shared equipment while providing cross-circulation through the lab support zone• Utilizing open laboratory layout with one or more “ghost〞corridors for intra lab circulation• And, most importantly, concentrating non-laboratory functions into an adjoining, lower-cost structure (as discussed in detail above).To further control laboratory construction costs, non-standard fume hood sizes are minimized, “generic〞lab casework is specified, laboratory-grade movable tables substitute for fixed casework in some lab bays, building DI systems provide intermediate water quality (with localized water purity polishing in the lab, rather than building-wide),facility-wide piped services do not include gases that can be cost-effectively provided locally via canisters, and glass-wash facilities are consolidated -- typically, one glass wash facility for an entire laboratory building.Finally, our design philosophy leans toward generic, modular laboratories supported by a robust building infrastructure, rather than highly customized spaces with limited capacity to make later changes. This is an important trade off. Although some post-occupancy expenses may be necessary to “fine-tune〞a laboratory to a PI’s requirements, building infrastructure elements – typically over sized twenty percent, including HVAC supply ducts, exhaust system capacity, emergency generator capacity, and electric risers and service capacity – seldom limit the ability to modify labs to meet researcher needs.Structural and Foundation SystemsFor both cost-benefit reasons and past seismic performance, UC Irvine favors concrete shear wall or steel braced-frame structural systems. The correlating foundation systems depend on site-specific soil conditions. Past problems with undiscovered substrates and uncharacterized soil conditions are minimized through extensive, pre-design soil-testing. This minimizes risk to both the University and the design/build contractor.When feasible, design/build contractors are allowed flexibility to propose alternate structural or seismic-force systems. All structural system designs must pass a peer review, according to Regents’ policy. This process results in conservative structural design, and an associated cost premium. However, the seismic performance of University of California buildings constructed since this policy went into effect in 1975 appears to substantiate the value of the Regents’ Seismic Revi ew Policy.Structural vibration is carefully specified in research buildings where vibration-sensitive protocols and conditions must be maintained on above-grade floors. The most cost effective tools to control vibration are generally employed: first, to program vibration sensitive procedures at on-grade locations or to isolate them at the bench; second, to space columns at a distance that does not entail excessive structural costs. In laboratory 4buildings we typically utilize 22 ft. X 22 ft. column-spacing. Conversely, where vibration is not problematic a beam/column system can be cost-optimized and lighter floor loading can be tolerated. Design/build contractors are, accordingly, allowed more flexibility under such conditions.To control costs, UC Irvine avoids use of moment-resisting structures; unconventionalseismic systems; non-standard structural dimensions; inconsistent, unconventional, or non-stacking structural modules; and non-standard means and methods.Roofs and FlashingsUC Irvine specifies 20 year roofing systems and stainless steel or copper flashings whenever possible. At minimum, we specify hot-dip galvanized flashings.Why this emphasis on flashings? Our roof replacement projects typically double in cost when the old roofing is torn off and it is determined that the flashings have deteriorated. Moreover, many roof leaks of recent years have been due to faulty flashings, rather than roofing membranes or coatings, per se. Saving money on flashings is false economy. Another special roofing expe nse we may have to incur in order to attain the Regents’ Green Building Policy is that of reflective roofing. It is too early to understand the potential cost impact.中文翻译：建立标准和本钱加州大学欧文分校新建筑追求性能目标和适用的质量标准,影响资本本钱的工程。

工程造价专业外文文献翻译(中英文对照外文文献：Project Cost Control: The Way it WorksBy R. Max WidemanIn a recent consulting assignment we realized that there was some lack of understanding of the whole system of project cost control, how it is setup and applied. So we decided to write up a description of how it works. Project cost control is not that difficult to follow in theory.First you establish a set of reference baselines. Then, as work progresses, you monitor the work, analyze the findings, forecast the end results and compare those with the reference baselines. If the end results are not satisfactory then you make adjustments as necessary to the work in progress, and repeat the cycle at suitable intervals. If the end results get really out of line with the baseline plan, you may have to change the plan. More likely, there will be (or have been) scope changes that change the reference baselines which means that every time that happens you have to change the baseline plan anyway.But project cost control is a lot more difficult to do in practice, as is evidenced by the number of projects that fail to contain costs. It also involves a significant amount of work, as we shall see, and we might as well start at the beginning. So let us follow the thread of project cost control through the entire project life span.And, while we are at it, we will take the opportunity to point out the proper places for several significant documents. These include the Business Case, the Request for (a capital) Appropriation (for execution), Work Packages and the Work Breakdown Structure, the Project Charter (or Brief), the Project Budget or Cost Plan, Earned Value and the Cost Baseline. All of these contribute to the organization's ability to effectively control project costs.FootnoteI am indebted to my friend Quentin Fleming, the guru of Earned Value, for checking and correcting my work on this topic.The Business Case and Application for (execution) FundingIt is important to note that project cost control is most effective when the executive management responsible has a good understanding of how projects should unfold through the project life span. This means that they exercise their responsibilities at the key decision pointsbetween the major phases. They must also recognize the importance of project risk management for identifying and planning to head off at least the most obvious potential risk events.In the project's Concept Phase• Every project starts with someone identifying an opportunity or need. That is usually someone of importance or influence, if the project is to proceed, and that person often becomes theproject's sponsor.• To determine the suitability of the potential project, most organizations call for the preparation of a "Business Case" and its "Order of Magnitude" cost to justify the value of the project so that it can be compared with all the other competing projects. This effort is conducted in the Concept Phase of the project and is done as a part of the organization's management of the entire project portfolio.• The cost of the work of preparing the Business Case is usually covered by corporate management overhead, but it may be carried forward as an accounting cost to the eventual project. No doubt because this will provide a tax benefit to the organization. The problem is, how do you then account for all the projects that are not so carried forward?• If the Business case has sufficient merit, approval will be given to proceed to a Development and Definition phase.In the project's Development or Definition Phase• The objective of the Development Phase is to establish a good understanding of the work involved to produce the required product, estimate the cost and seek capital funding for the actual execution of the project.• In a formalized set ting, especially where big projects are involved, this application for funding is often referred to as a Request for (a capital) Appropriation (RFA) or Capital Appropriation Request (CAR).• This requires the collection of more detailed requirements and da ta to establish what work needs to be done to produce the required product or "deliverable". From this information, a plan is prepared in sufficient detail to give adequate confidence in a dollar figure to be included in the request.• In a less formalized setting, everyone just tries to muddle through.Work Packages and the WBSThe Project Management Plan, Project Brief or Project Charter• If the deliverable consists of a number of different elements, these are identified and assembled into Work Packages (WPs) and presented in the form of a Work Breakdown Structure (WBS). • Each WP involves a set of activities, the "work" that is planned and scheduled as a part of the Project Management Plan. Note, however, that the planning will still be at a relatively high level, and more detailed planning will be necessary during execution if the project is given the go ahead. • This Project Management Plan, by the way, should become the "bible" for the execution phase of the project and is sometimes referred to as the "Project Brief" or the "Project Charter".• The cost of doing the various activities is then estimated and these estimated costs are aggregated to determine the estimated cost of the WP. This approach is known as "detailed estimating" or "bottom up estimating". There are other approaches to estimating that we'll cometo in a minute. Either way, the result is an estimated cost of the total work of the project.Note: that project risk management planning is an important part of this exercise. This should examine the project's assumptions and environmental conditions to identify any weaknesses in the plan thus far, and identify those potential risk events that warrant attention for mitigation. This might take the form of specific contingency planning, and/or the setting aside of prudent funding reserves.Request for capitalConverting the estimate• However, an estimate of the work alone is not sufficient for a capital request. To arrive at a capital request some conversion is necessary, for example, by adding prudent allowances such as overheads, a contingency allowance to cover normal project risks and management reserves to cover unknowns and possible scope changes.• In addition, it may be necessary to convert the estimating data into a financial accou nting format that satisfies the corporate or sponsor's format for purposes of comparison with other projects and consequent funding approval.• In practice all the data for the type of "bottom up" approach just described may not be available. In this case alternative estimating approaches are adopted that provide various degrees of reliability in a "top down" fashion. For example:Order of Magnitude estimate – a "ball park" estimate, usually reserved for the concept phase onlyAnalogous estimate – an estimate based on previous similar projectsParametric estimate – an estimate based on statistical relationships in historical data• Whichever approach is adopted, hopefully the sum thus arrived at will be approved in full and proves to be satisfactory! This is the trigger to start the Execution Phase of the projectNote: Some managements will approve some lesser sum in the mistaken belief that this will help everyone to "sharpen their pencils" and "work smarter" for the benefit of the organization. This is a mistaken belief because management has failed to understand the nature of uncertainty and risk in project work. Consequently, the effect is more likely to result in "corner cutting" with an adverse effect on product quality, or reduced product scope or functionality. This often leads to a "game" in which estimates are inflated so that management can adjust them downwards. But to be fair, management is also well aware that if money is over allocated, it will get spent anyway. The smart thing for managements to do is to set aside contingent reserve funds, varying with the riskiness of the project, and keep that money under careful control.Ownership of approved capital• If senior management approves the RFA as presented, the sum in question becomes the responsibility of the designated project sponsor. However, if the approved capital request includes allowances such as a "Management Reserve", this may or may not be passed on to the project's sponsor, depending on the policies of the organization.• For the approved RFA, the project sponsor will, in turn, further delegate expenditure authority to the project's project manager and will likely not include any of the allowances. An exception might be the contingency allowances to cover the normal variations in work performance.• The net sum thus arrived at constitutes the project manager's Approved Project Budget.Note: If management does not approve the RFA, you should not consider this a project failure. Either the goals, objectives, justification and planning need rethinking to increase the value of the project's deliverables, or senior management simply has higher priorities elsewhere for the available resources and funding.The Project's Execution PhaseThe project manager's Project Budget responsibility• Once this Approved Project Budget is released to the project manager, a reverse process must take place to convert it into a working control document. That is, the money available must be divided amongst the various WBS WPs that, by the way, have probably by now been upgraded! This results in a project execution Control Budget or Project Baseline Budget, or simply, the Project Budget. In some areas of project management application it is referred to as a Project Cost Plan.• On a large project where differe nt corporate production divisions are involved, there may be a further intermediate step of creating "Control Accounts" for the separate divisions, so that each division subdivides their allocated money into their own WBS WPs.• Observe that, since the tot al Project Budget received formal approval from Executive Management, you, as project manager, must likewise seek and obtain from Executive Management, via the project's sponsor, formal approval for any changes to the total project budget. Often this is only justified and accepted on the basis of a requested Product Scope Change.• In such a case the project's sponsor will either draw down on the management reserve in his or her possession, or submit a supplementary RFA to upper management.• Now that we ha ve the Project Budget money allocated to Work Packages we can further distribute it amongst the various activities of each WP so that we know how much money we have as a "Baseline" cost for each activity.• This provides us with the base of reference for t he cost control function. Of course, depending on the circumstances the same thing may be done at the WP level but the ability to control is then at a higher and coarser level.Use of the Earned Value technique• If we have the necessary details another control tool that we can adopt for monitoring ongoing work is the "Earned Value" (EV) technique. This is a considerable art and science that you must learn about from texts dedicated to the subject.• But essentially, you take the costs of the schedule act ivities and plot them as a cumulative total on the appropriate time base. Again you can do this at the activity level, WP level or the whole project level. The lower the level the more control information you have available but the more work you get involved in.The Cost Baseline• This planned reference S-curve is sometimes referred to as the "Cost Baseline", typically in EV parlance. That is, it is the "Budgeted Cost of Work Scheduled" (BCWS), or more simply the "Planned Value" (PV).• Observe that you need to modify this Cost Baseline every time there is an approved scope change that has cost and/or schedule implications and consequently changes the project's Approved Project Budget.• Now, as the work progresses, you can plot the "Actual Cost of Work Per formed" (ACWP or simply "Actual Cost" - AC).• You can plot other things as well, see diagram referred to above, and if you don't like what you see then you need to take "Corrective Action".CommentaryThis whole process is a cyclic, situational operation and is probably the source of the term "cycle" in the popularly misnamed "project life cycle".As an aside, the Earned Value pundits offer various other techniques within the EV process designed to aid in forecasting the final result, that is, the "Estimate At Completion" (EAC). EAC is what you should really be interested in because it is the only constant in a moving project. Therefore, these extended EV techniques must be considered in the same realm of accuracy as top-down estimating. They are useful, but only if you recognize the limitations and know what you are doing!But, as we said at the beginning, it is a lot more difficult to do in practice – and involves a significant amount of work. But, let's face it, that's what project managers are hired for, right?中文译文：项目成本控制：它的工作方式R.马克斯怀德曼我们在最近的咨询任务中意识到，对于整个项目成本控制体系是如何设置和应用的这个问题，我们仍有一些缺乏了解。

中英文对照翻译Risk Analysis of the International Construction ProjectABSTRACTThis analysis used a case study methodology to analyse the issues surrounding the partial collapse of the roof of a building housing the headquarters of the Standards Association of Zimbabwe (SAZ). In particular, it examined the prior roles played by the team of construction professionals. The analysis revealed that the SAZ‟s traditional construction project was generally characterized by high risk. There was a clear indication of the failure of a contractor and architects in preventing and/or mitigating potential construction problems as alleged by the plaintiff. It was reasonable to conclude that between them the defects should have been detected earlier and rectified in good time before the partial roof failure. It appeared justified for the plaintiff to have brought a negligence claim against both the contractor and the architects. The risk analysis facilitated, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects. It further served to emphasize the point that clients are becoming more demanding, more discerning, and less willing to accept risk without recompense. Clients do not want surprise, and are more likely to engage in litigation when things go wrong.KEY WORDS:Arbitration, claims, construction, contracts, litigation, project and risk The structural design of the reinforced concrete elements was done by consulting engineers Knight Piesold (KP). Quantity surveying services were provided by Hawkins, Leshnick & Bath (HLB). The contract was awarded to Central African Building Corporation (CABCO) who was also responsible for the provision of a specialist roof structure using patented “gang nail” roof trusses. The building construction proceeded to completion and was handed over to the owners on Sept. 12, 1991. The SAZ took effective occupation of the headquarters building without a certificate of occupation. Also, the defects liability period was only three months .The roof structure was in place 10 years before partial failure in December 1999. The building insurance coverage did not cover enough, the City of Harare, a government municipality, issued the certificate of occupation 10 years after occupation, and after partial collapse of the roof .At first the SAZ decided to go to arbitration, but this failed to yield an immediate solution. The SAZ then decided to proceed to litigate in court and to bring a negligence claim against CABCO. The preparation for arbitration was reused for litigation. The SAZ‟s quantified losses stood at approximately $ 6 million in Zimbabwe dollars (US $1.2m) .After all parties had examined the facts and evidence before them, it became clear that there was a great probability that the courts might rule that both the architects and the contractor were liable. It was at this stage that the defendants‟ lawyers requested that the matter be settled out of court. The plaintiff agreed to this suggestion, with the terms of the settlement kept confidential .The aim of this critical analysis was to analyse the issues surrounding the partial collapse of the roof of the building housing the HQ of Standard Association of Zimbabwe. It examined the prior roles played by the project management function and construction professionals in preventing/mitigating potential construction problems. It further assessed the extent to which the employer/client and parties to a construction contract are able to recover damages under that contract. The main objective of this critical analysis was to identify an effective risk management strategy for future construction projects. The importance of this study is its multidimensional examination approach.Experience suggests that participants in a project are well able to identify risks based on their own experience. The adoption of a risk management approach, based solely in past experience and dependant on judgement, may work reasonably well in a stable low risk environment. It is unlikely to be effective where there is a change. This is because change requires the extrapolation of past experience, which could be misleading. All construction projects are prototypes to some extent and imply change. Change in the construction industry itself suggests that past experience is unlikely tobe sufficient on its own. A structured approach is required. Such a structure can not and must not replace the experience and expertise of the participant. Rather, it brings additional benefits that assist to clarify objectives, identify the nature of the uncertainties, introduces effective communication systems, improves decision-making, introduces effective risk control measures, protects the project objectives and provides knowledge of the risk history .Construction professionals need to know how to balance the contingencies of risk with their specific contractual, financial, operational and organizational requirements. Many construction professionals look at risks in dividually with a myopic lens and do not realize the potential impact that other associated risks may have on their business operations. Using a holistic risk management approach will enable a firm to identify all of the organization‟s business risks. This will increas e the probability of risk mitigation, with the ultimate goal of total risk elimination .Recommended key construction and risk management strategies for future construction projects have been considered and their explanation follows. J.W. Hinchey stated th at there is and can be no …best practice‟ standard for risk allocation on a high-profile project or for that matter, any project. He said, instead, successful risk management is a mind-set and a process. According to Hinchey, the ideal mind-set is for the parties and their representatives to, first, be intentional about identifying project risks and then to proceed to develop a systematic and comprehensive process for avoiding, mitigating, managing and finally allocating, by contract, those risks in optimum ways for the particular project. This process is said to necessarily begin as a science and ends as an art .According to D. Atkinson, whether contractor, consultant or promoter, the right team needs to be assembled with the relevant multi-disciplinary experience of that particular type of project and its location. This is said to be necessary not only to allow alternative responses to be explored. But also to ensure that the right questions are asked and the major risks identified. Heads of sources of risk are said to be a convenient way of providing a structure for identifying risks to completion of a participant‟s part of the project. Effective risk management is said to require amulti-disciplinary approach. Inevitably risk management requires examination of engineering, legal and insurance related solutions .It is stated that the use of analytical techniques based on a statistical approach could be of enormous use in decision making . Many of these techniques are said to be relevant to estimation of the consequences of risk events, and not how allocation of risk is to be achieved. In addition, at the present stage of the development of risk management, Atkinson states that it must be recognized that major decisions will be made that can not be based solely on mathematical analysis. The complexity of construction projects means that the project definition in terms of both physical form and organizational structure will be based on consideration of only a relatively small number of risks . This is said to then allow a general structured approach that can be applied to any construction project to increase the awareness of participants .The new, simplified Construction Design and Management Regulations (CDM Regulations) which came in to force in the UK in April 2007, revised and brought together the existing CDM 1994 and the Construction Health Safety and Welfare (CHSW) Regulations 1996, into a single regulatory package.The new CDM regulations offer an opportunity for a step change in health and safety performance and are used to reemphasize the health, safety and broader business benefits of a well-managed and co-ordinated approach to the management of health and safety in construction. I believe that the development of these skills is imperative to provide the client with the most effective services available, delivering the best value project possible.Construction Management at Risk (CM at Risk), similar to established private sector methods of construction contracting, is gaining popularity in the public sector. It is a process that allows a client to select a construction manager (CM) based on qualifications; make the CM a member of a collaborative project team; centralize responsibility for construction under a single contract; obtain a bonded guaranteed maximum price; produce a more manageable, predictable project; save time and money; and reduce risk for the client, the architect and the CM.CM at Risk, a more professional approach to construction, is taking its place along with design-build, bridging and the more traditional process of design-bid-build as an established method of project delivery.The AE can review the CM‟s approach to the work, making helpful recommendations. The CM is allowed to take bids or proposals from subcontractors during completion of contract documents, prior to the guaranteed maximum price (GMP), which reduces the CM‟s risk and provides useful input to design. The procedure is more methodical, manageable, predictable and less risky for all.The procurement of construction is also more business-like. Each trade contractor has a fair shot at being the low bidder without fear of bid shopping. Each must deliver the best to get the projec. Competition in the community is more equitable: all subcontractors have a fair shot at the work .A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes. As long as the subcontractors are within the GMP they are reimbursed to the CM, so the CM represents the client in negotiating inevitable changes with subcontractors.There can be similar problems where each party in a project is separately insured. For this reason a move towards project insurance is recommended. The traditional approach reinforces adversarial attitudes, and even provides incentives for people to overlook or conceal risks in an attempt to avoid or transfer responsibility.A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes.

It did appearjustified for the plaintiff to have brought a negligence claim against both the contractor and the architects.In many projects clients do not understand the importance of their role in facilitating cooperation and coordination; the design is prepared without discussion between designers, manufacturers, suppliers and contractors. This means that the designer can not ta ke advantage of suppliers‟ or contractors‟ knowledge of build ability or maintenance requirements and the impact these have on sustainability, the total cost of ownership or health and safety .This risk analysis was able to facilitate, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects. This work also served to emphasize the point that clients are becoming more demanding, more discerning, and less willing to accept risk without recompense. They do not want surprises, and are more likely to engage in litigation when things go wrong.国际建设工程风险分析摘要此次分析用实例研究方法分析津巴布韦标准协会总部（SAZ）的屋顶部分坍塌的问题。

They must also recognize the importance of project risk management for identifying and planning to head off at least the most obvious potential risk events.In the project's Concept Phase• EvEry projEct starts with somEonE idEntifying an opportunity or need. That is usually someone of importance or influence, if the project is to proceed, and that person often becomes the project's sponsor.• to dEtErminE thE suitability of thE potEntial projEct, most organizations call for the preparation of a "Business Case" and its"Order of Magnitude" cost to justify the value of the project so that it can be compared with all the other competing projects. This effort is conducted in the Concept Phase of the project and is done as a part of the organization's management of the entire project portfolio.• thE cost of thE work of preparing the Business Case is usually covered by corporate management overhead, but it may be carried forward as an accounting cost to the eventual project. No doubt because this will provide a tax benefit to the organization. The problem is, how do you then account for all the projects that are not so carried forward?• if thE businEss casE has sufficiEnt mErit, approval will bE givEn to proceed to a Development and Definition phase.In the project's Development or Definition Phase• thE objEctivE of t he Development Phase is to establish a good understanding of the work involved to produce the required product, estimate the cost and seek capital funding for the actual execution of the project.• in a formalizEd sEtting, EspEcially whErE big projEcts arE involved, this application for funding is often referred to as a Request for (a capital) Appropriation (RFA) or Capital Appropriation Request (CAR).• this rEquirEs thE collEction of morE dEtailEd rEquirEmEnts and data to establish what work needsto be done to produce the required product or "deliverable". From this information, a plan is prepared in sufficient detail to give adequate confidence in a dollar figure to be included in the request.• in a lEss formalizEd sEtting, EvEryonE just triEs to muddlE through.Work Packages and the WBSThe Project Management Plan, Project Brief or Project Charter• if thE dElivErablE consists of a numbEr of diffErEnt ElEmEnts, thEsE are identified and assembled into Work Packages (WPs) and presented in the form of a Work Breakdown Structure (WBS).• Each wp involvEs a sEt of activitiEs, thE "work" that is plannEd and scheduled as a part of the Project Management Plan. Note, however, that the planning will still be at a relatively high level,and more detailed planning will be necessary during execution if the project is given the go ahead.• this projEct managEmEnt plan, by thE way, should bEcomE thE "bible" for the execution phase of the project and is sometimes referred to as the "Project Brief" or the "Project Charter".• thE cost of doing thE various activitiEs is thEn EstimatEd and thEsE estimated costs are aggregated to determine the estimated cost of the WP. This approach is known as "detailed estimating" or "bottom up estimating". There are other approaches to estimating that we'll come to in a minute. Either way, the result is an estimated cost of the totalwork of the project.Note: that project risk management planning is an important part of this exercise. This should examine the project's assumptions and environmental conditions to identify any weaknesses in the plan thus far, and identify those potential risk events that warrant attention for mitigation. This might take the form of specific contingency planning, and/or the setting aside of prudent funding reserves.Request for capitalConverting the estimate• howEvEr, an EstimatE of thE work alonE is not sufficiEnt for a capital request. To arrive at a capital request some conversion is necessary, for example, by adding prudent allowances such as overheads, a contingency allowance to cover normal project risks and management reserves to cover unknowns and possible scope changes.• in addition, it may bE nEcEssary to convErt thE Estimating data into a financial accounting formatthat satisfies the corporate or sponsor's format for purposes of comparison with other projects and consequent funding approval.• in practicE all thE data for thE typE of "bottom up" approach just described may not be available.In this case alternative estimating approaches are adopted that provide various degrees of reliability in a "top down" fashion. Forexample:Order of Magnitude estimate – a "ball park" estimate, usually reserved for the concept phase onlyAnalogous estimate – an estimate based on previous similar projects Parametric estimate –an estimate based on statistical relationships in historical data• whichEvEr approach is adoptEd, hopEfully thE sum thus arrivEd at will be approved in full and proves to be satisfactory! This is the trigger to start the Execution Phase of the projectNote: Some managements will approve some lesser sum in the mistaken belief that this will help everyone to "sharpen their pencils" and "work smarter" for the benefit of the organization. This is a mistaken belief because management has failed to understand the nature of uncertainty and risk in project work. Consequently, the effect is more likely to result in "corner cutting" with an adverse effect on product quality, or reduced product scope or functionality. This often leads to a "game" in which estimates are inflated so that management can adjust them downwards. But to be fair, management is also well aware that if money is over allocated, it will get spent anyway. The smart thing for managements to do is to set aside contingent reserve funds, varying with the riskiness of the project, and keep that money under careful control.Ownership of approved capital• if sEnior managEmEnt approvEs thE rfa as prEsEntEd, thE sum in question becomes the responsibility of the designated project sponsor. However, if the approved capital request includes allowances such as a "Management Reserve", this may or may not be passed on to the project's sponsor, depending on the policies of the organization.• for thE approvEd rfa, thE projEct sponsor will, in turn, further delegate expenditure authority to the project's project manager and will likely not include any of the allowances. An exception might be the contingency allowances to cover the normal variations in work performance.• thE nEt sum thus arrivEd at constitutes the project manager's Approved Project Budget.Note: If management does not approve the RFA, you should not consider this a project failure. Either the goals, objectives, justification and planning need rethinking to increase the value of the project's deliverables, or senior management simply has higher priorities elsewhere for the available resources and funding.The Project's Execution PhaseThe project manager's Project Budget responsibility• oncE this approvEd projEct budgEt is rElEas ed to the project manager, a reverse process must take place to convert it into a working control document. That is, the money available must be divided amongstthe various WBS WPs that, by the way, have probably by now been upgraded! This results in a project execution Control Budget or Project Baseline Budget, or simply, the Project Budget. In some areas of project management application it is referred to as a Project Cost Plan.• on a largE projEct whErE diffErEnt corporatE production divisions are involved, there may be a further intermediate step of creating "Control Accounts" for the separate divisions, so that each division subdivides their allocated money into their own WBS WPs.• obsErvE that, sincE thE total projEct budgEt rEcEivEd formal approval from Executive Management, you, as project manager, must likewise seek and obtain from Executive Management, via the project's sponsor, formal approval for any changes to the total project budget. Often this is only justified and accepted on the basis of a requested Product Scope Change.• in such a casE thE projEct's sponsor will EithEr draw down on thE management reserve in his or her possession, or submit a supplementary RFA to upper management.• now that wE havE thE projEct budgEt monEy allocatEd to Work Packages we can further distribute it amongst the various activities of each WP so that we know how much money we have as a "Baseline" cost for each activity.• this providEs us with thE basE of rEfErEncE for thE cost controlfunction. Of course, depending on the circumstances the same thing may be done at the WP level but the ability to control is then at a higher and coarser level.Use of the Earned Value technique• if wE havE thE nEcEssary dEtails anothEr control tool that wE can adopt for monitoring ongoing work is the "Earned Value" (EV) technique. This is a considerable art and science that you must learn about from texts dedicated to the subject.• but EssEntially, you takE thE costs of thE schEdulE activitiEs and plot them as a cumulative total on the appropriate time base. Again you can do this at the activity level, WP level or the whole project level. The lower the level the more control information you have available but the more work you get involved in.The Cost Baseline• this plannEd reference S-curve is sometimes referred to as the "Cost Baseline", typically in EVparlance. That is, it is the "Budgeted Cost of Work Scheduled" (BCWS), or more simply the "Planned Value" (PV).• Observe that you need to modify this Cost Baseline every time there is an approved scope change that has cost and/or schedule implications and consequently changes the project's Approved Project Budget.• now, as thE work progrEssEs, you can plot thE "actual cost of workPerformed" (ACWP or simply "Actual Cost" - AC).• you can plot othEr things as wEll, sEE diagram rEfErrEd to abovE, and if you don't like what you see then you need to take "Corrective Action".CommentaryThis whole process is a cyclic, situational operation and is probably the source of the term "cycle" in the popularly misnamed "project life cycle".As an aside, the Earned Value pundits offer various other techniques within the EV process designed to aid in forecasting the final result, that is, the "Estimate At Completion" (EAC). EAC is what you should really be interested in because it is the only constant in a moving project. Therefore, these extended EV techniques must be considered in the same realm of accuracy as top-down estimating. They are useful, but only if you recognize the limitations and know what you are doing!But, as we said at the beginning, it is a lot more difficult to do in practice –and involves a significant amount of work. But, let's face it, that's what project managers are hired for, right?中文译文：项目成本控制：它的工作方式R.马克斯怀德曼我们在最近的咨询任务中意识到，对于整个项目成本控制体系是如何设置和应用的这个问题，我们仍有一些缺乏了解。

英文文献Engineering cost managementProject cost control emphasis should be transferred to the project construction early days, is transferred to the project decision and design stage. Project cost control in construction projects throughout the entire process, the key lies in the pre construction investment decision-making with design phase, whereas in the investment decision is made, the key lies in designing. According to expert analysis: architectural design, in the preliminary design stage, design stage, construction design stage to the engineering effect were 75% ~ 95%, 35% ~ 75%, 5% ~ 35%; while in the construction phase, through the optimization of construction organization design, construction cost saving the possibility of only 5% to 10%. We should put the focus shifted to the design stage, in order to get twice the result with half the effort.Pay attention to the technical and economic optimization combination. The combination of technology with economy is most effective way to control engineering cost. China engineering fields for a long time did not do this. The lack of technical personnel economy idea, design thought is conservative, the design of the outcome of the economy are not fully reflect. Therefore, we should solve the problem is to improve economic efficiency as the goal, in the construction process, organization, technology and economy organic ground union rises. Through the economic analysis, comparative study and effect evaluation, correct processing of advanced technology and reasonable in economy between the relation of unity of opposites, strive to advanced technology under the conditions of economic rational, reasonable in economy based on advanced technology.Carry out "limitation is designed" method. To be consciously put the application of value engineering to the specific design, actively promote quota design in engineering design contract, by way of bidding. This has been proven in practice is an effective way, it is not only an economic problem, more precisely a technical and economic problems. This "limitation is designed" to effectively control the project cost. In order to make the "limitation is designed" to achieve the desired objectives, should be involved in the design personnel must be experienced skilled economic designer. Their design results must be practical, advanced and reasonable cost. Control of engineering cost on the other hand is the need for comparison, because the outcome is a process of gradual improvement, and not to decide, so the comparison is a measure of its practical, advanced and economical means.Do good project cost control in the process. ( 1) compilation of economic and feasible construction scheme. Before construction, construction enterprises should be combined with the construction drawings and the actual situation at the scene, their mechanical equipment, construction experience, the management level and technical specification acceptance criteria, a set of practical and feasible construction scheme. The construction scheme is engineering implementation of the programme of action. ( 2) to technical personnel, materials, machinery and personnel staff communicationand coordination. In the process of construction, construction technology, materials and mechanical personnel should cooperate closely, understand each other, to management as the core, to reduce costs for the purpose of.

To establish a real sense of independent engineering cost consulting agencies. Through improving the laws and regulations, normative behavior, separate government functions from enterprise management, the establishment of independent business partnership, share-holding system, the limited responsibility system and other forms of organization, an industry-based, diversified services integrated project consulting company, build and development and reform the engineering cost intermediary service institutions, make construction project management of a gradual transition by an independent specialized agency in charge of project cost whole process tracking management, truly between owner and contractor plays an intermediary role. To strengthen engineering cost consulting industry association construction, establish project cost consulting industry self-discipline mechanism, and constantly improve the Engineering Cost Association in engineering cost consulting industry status, to be truly representative of the interests of the majority of the industry practitioners, government and enterprises to become connection link and the bridge. At the same time to strengthen the project cost specialty in higher education and in service education. As a result of project cost management in construction projects and various economic interests are closely related, and the whole social economic activities play a very important role, it requires the cost engineering technical personnel should have different levels of knowledge, in addition to their professional knowledge and have a deep understanding, also deal with the design content, design process, construction technology, project management, economic laws and regulations have a comprehensive understanding of. Therefore, the project cost management, project cost per unit of society groups, has already obtained a cost engineer qualification personnel, in order to carry out plan, has the goal, multiple levels of continuing education and training, to understand and master Chinese bilateral agreements with countries project cost technology, regulations, management system and its development trend, to expand domestic and foreign exchanges, and actively participate in international or regional engineering activities, improve their professional quality, so that the current practitioners in intelligentstructure, theory and working experience three aspects can meet the needs of engineering cost management. Cost engineering professionals need to strengthen their own learning, in addition to the professional knowledge to upgrade, should also work in combination with a broad understanding and master the relevant engineering and technical expertise, educational organizations and industry regulatory bodies constitute a complete education system, so as to the field of engineering senior talent development to create good conditions.中文译文：工程造价与管理工程造价控制重点应转移到项目建设的前期，即转移到项目决策和设计阶段。

AbstractProject cost management is the basic contents to determine reasonable and effective control of the project cost. Described the current stage of the project cost management situation on the strengthening of the various stages of construction cost management of the importance of and raised a number of key initiatives.Keywords：cost of the construction project cost management status investment decision phase of the design phase of the implementation phase of the cost management in a market economy.Even under the WTO and China's accession to the world community, China's construction industry how to effectively control construction cost of the construction and management of an important component part. However, the current budget for the construction projects - estimate, budget, Super budget accounts for the "super three" is still widespread and that eventually led to a serious loss of control of project investment. Project cost management is the basic contents to determine reasonable and effective control of the project cost.As the project cost to the project runs through the entire process, stage by stage can be divided into Investment Decision stage, the design and implementation phases. The so-called Project Cost effective control is the optimization of the construction plans and design programs on the basis of in the building process at all stages, use of certain methods and measures to reduce the cost of the projects have a reasonable control on the scope and cost of the approved limits.Engineering and cost management work of the current status of project cost management system was formed in the 1950s, 1980s perfect together. Performance of the country and directly involved in the management of economic activities. Provisions in the design stage to different estimates or budget preparation as well as government; Nothing relevant departments to formulate a budget, content, methods and approval, the budget will provide the fixed cost of equipment and materials and fixed price of the budget preparation, approval, management authority, and so on.With the historical process, after recovery, reform and development, formed a relatively complete budget estimate of quota management system. However, as the socialist market economic development, the system's many problems have also exposed. Generally speaking, the budget estimate is based on direct participation in the management of national economic activity as a precondition. enterprise is not the actual economic entities. Due to the characteristics of the planned economy, and, at the time under the conditions of productivity, will inevitably become a shortage in the economy.In severe shortage of commodities under the conditions, as long as a certain level of investment, will be certain outputs. In this environment, the project planning and technical argumentation there can be no economic analysis. State control of the project cost constitute key factors equipment and materials prices, wages and taxes of artificial distribution. In this relatively stable economic environment, the budget estimate for the system approved project cost, help the government to carry out investment plans to play a major role.As the socialist market economic system established, requires us to predict project investment and control. In recent years, international investment project developed to the requirements of prior pre-control and in the middle of control. China, the traditional practice in an objective light on the cause decision-making, implementation heavy, light the economy and technology,First, the consequences of victimization,Due to the technical personnel of the project technical and economic concepts and a weak awareness of cost control, cost management makes the quality difficult to raise. Project Cost control is difficult to achieve long-term goals.Second, the various stages of the project management view of the above circumstances, My first academia in the 1980s made the whole process of cost management and control concept, building departments will study the feasibility of projects and the budgets and final accounts to two extended at the request of the corresponding regulations put our cost management concepts and methods referred to a new height.Our task now is to be modern and cost management in line with China's national conditions of the market economy system goal, learn from the advanced experience of the developed countries, and establish sound market economic laws of project cost management system, efforts to increase the project cost levels. An investment decision-making phase of the project cost management construction project investment decision-making stage is proposed project proposals; conduct a feasibility study to determine investment estimation and the final preparation of design task. At this stage, the project's technical and economic decision-making, of the construction project cost of the project after the completion of the economic benefits have a decisive influence, The construction cost is an important stage control.China's current stage of the project cost for the project management for the purpose of clearing price, and focusing only on the construction process of cost control, neglected before the start of the project investment decision-making stage of cost control. Investment decision-making phase of investment projects is estimated an important basis for decision-making. It has a direct impact on national economic and financial analysis of the results of the reliability and accuracy. Because of this phase is the preliminary work of projects, the information can not be fully, comparable works more or less that information accumulated relatively small, estimated inadequate and unscientific. Makes project cost management and cost workers is difficult at this stage do something.The various stages of the project cost control in the decision-making phase project cost control. Right project planning phase of the cost, many owners have the wrong understanding that the lower the cost the better. Cost control is not a unilateral issue, and should be a number of factors, a combination of practical, comprehensive consideration. The construction project investment decision-making stage, the project's technical and economic decision-making, Cost of the project after the completion of the project and the economic benefits, with a decisive role in project cost control is an important stage, rationally define and control the direction of the project cost of accurate positioning and building Optimization guiding role.In the decision-making phase of the most important is to do a good job feasibility study, the work is done well, returns on investment and can form a good proportion. Otherwise, invest more, less effective, resulting in loss of control and waste of investment.At present, some of the projects planned the owners of departure from the subjective desires of a feasibility study on the lack of scientific proof. Feasibility Study untrue, false or engineering functions obtaining the approval of their superiors, actually put into the feasibility study will be awarded in the study for the project after the smooth functioning buried a lot of hidden problems, lead to insufficient follow-up funds for the project and had to extend the time limit so that the project could not have planned the use of cost-effective, even become hopeless completion of the beard works.Therefore, in order to phase in the investment decision-making effectively control construction costs, we must do the following aspects:ⅰImplementation of the construction project and corporate accountability, Construction of the project from planning to implementation of the entire process and the use of the funds to repay responsibilities to the people. in addition to establishing a legal system and the project supervision matching mechanism by the departments in charge of the industry and supervision departments for setting up a monitoring group to oversee the use of funds.ⅱA realistic approach to market analysis, to avoid the blindness of the project decision-making, reduces and reduces investment risk. Fully consider building projects in the future market competitiveness, design task more scientific and reliability.ⅲCapital financing must have a formal commitment document, the parties must do investment funds in place, and funds must have documents to ensure that the project can be approved after the scheduled implementation. To the various loan conditions should be carefully analyzed to minimize the burden of interest and repayment pressure.ⅳTo strengthen the engineering geology, hydrology, geology and land, water, electricity, transport, environmental projects such as external conditions for the work of depth to make the investment estimate there are sufficient grounds.Taking extensive investigation and research, comparison of similar projects, seriously functional analysis, multi-program comparison and choice. After full technical appraisal and economic evaluation, and the final technologically advanced, functional and reliable. Reasonable economic projects, thus calculate a more accurate and realistic estimation of the amount of investment, so that the project cost from the start positioning in a more reasonable level.The design phase of the project cost control for a long time, China's building control very effective, - investment projects is not uncommon, this will affect owners of investment returns, it adds to the owners and within budget, as well as difficulties in fund owners, the impact on the future management or the owners make payments in arrears, and so on. Hence, the control of the project cost is of great significance, however the project cost is the primary means of control design,Currently most of the property owners in the design stage seldom works on cost control, and they found that the cost of the design will not have a great impact, it is wrong, on the contrary, Design phase of the project cost control is the most important step. Because it determines engineering design, construction methods, materials and equipment types, models of the project cost is of critical significance, design optimization phase of the program or minor changes, project cost will have a significant impact, Design phase of the project cost control of the total project cost of 70%. Following is how to control the project from design to create the Law: ⅰAs the owners must design, the design selected on the quality level is a direct impact on the quality of product design level, and the design quality products in the level of direct influence on the pricing of the works. Different design units on the same project design are different. the same item of different design institute works between certain aspects of the project cost on the existence of differences between, We assume that with a design from two different design institute to design, Construction plans after the completion of a requested advisory unit cost to do thebudget, certainly different design institute the total cost of the project is absolutely not the same, and most of the difference between the two over 10% even more than 30%, and not necessarily high cost than the design of low cost, and good design is often low cost, We all know that different people have different design styles and different levels, the design works naturally, therefore chosen to design units is the control on the first step. Through tender to select the design of the units is a good method, the tender documents to elaborate on this particular aspect of the requirements, cost control targets, and so on.Otherwise, in the subsequent design process design units will put an increase in the cost of the design requirements; through tendering the project design into the market, compared to select the best design units.ⅱPromoting the design bidding and design optimization campaign mode design units assessed by experts using scientific group France, in accordance with applicable, economic, aesthetic principles and advanced technology, reasonable structure to meet building energy efficiency and environmental requirements, comprehensive assessment of the merits of the program design, selection of the best determination of the successful program.Successful investment program estimated to be close to the general construction project scope of investment. This means two design contracts will help design the program of choice and competition to ensure that the selected design advanced technology, unique novelty, adaptability, as well as to control the cost of the project. Design units should strive to improve their quality of the project design clever idea, contemporary reducing the project cost on to rack their brains to improve design quality, strive to put the design phase of the project cost control approval of the investment ceiling.ⅲStrengthening the design stage of the design phase to strengthen supervision of the Commissioner to determine a reasonable design, mature technology, reduction in the construction phase major design changes and changes in the program, in the effective control of the project cost will play a role. 1 to the design of the project if the project supervision to get involved, excluding unfavorable factors may generally isexcluded from the 80% errors. In the entire process of building cost control, construction began at best to save and invest 20%, the key lies in the construction phase of the identification and control costs. Supervision of the design phase include : Design Institute under the design drawings and notes help owners deal with different design options for the economy, capital expenditure to develop the preliminary estimates, to ensure that the investment can be most effectively utilized. With the owners of the Commissioner include:According to the Design Institute to provide design drawings and notes to help owners deal with different design options for the economy, capital expenditures to develop the preliminary plan to ensure that investment can be most effectively used; with the owners of different design options, the need to calculate their own materials and equipment to conduct a cost analysis and study, to the design staff costs, to assist them in the investment limit within limits designed to save and invest. To seek aone-time small investment and economic good design program made the most rational economic indicators.ⅳDesign actively promote the so-called cap limit design, even with the approval of the design task and investment estimates, guarantee the functional requirements of the premise. The preliminary design and control budget, according to the preliminary approval of the total budget for the design and construction design control. Limits, and every one professional, each of whom have a design threshold of a target. In the design process, designers should progress to more programs, design optimization, ensuring that the design is technically advanced and reasonable, innovative, stylish, and do not break the limit investment objectives, thus eliminating the engineering design raise the factor of safety and design standards, or only consider the technical feasibility of the program, rather than economic rationality phenomenon, the project cost to ensure effective control.Also known as the value of value engineering analysis, is a modern scientific management technique, is a new techno-economic analysis, is the product of functional analysis to conserve resources and reduce the cost of the purpose of an effective method. It made up for the traditional cost management simply focus on costreduction and quality management only emphasizes improving the quality deficiencies, construction is conducive to resolving the long-standing long period, a lot of wastage, poor quality, high-cost problems. Value Engineering laws generally divided into three steps: assessment of the design of object technology and economic Score; Calculation of the target group of technical and economic indicators; calculate the geometric design of the object, on average; from comparison choose the best design.1985 summary, project cost control is a whole process of control, it should be said that every link is no room for complacency, and each one links are also important. With China's entry into the WTO, China was the main investment diversification, investment side of cost reduction, cost control, improves returns on investment increasing attention. Therefore, changes to the original construction cost estimate, budget, budget, contract prices, and the settlement price accounts for the completionof the move. Lack of continuity of the situation, the launch control system investment projects, investment in construction projects to improve the level of control. Can promote the country's socialist market economic development, adapt to the global economic integration process.摘要工程造价管理的基本内容,确定合理和有效控制工程造价。

工程造价论文中英文资料对照外文翻译Risk Analysis of the International Construction ProjectABSTRACTThis analysis used a case study methodology to analyse the issues surrounding the partial collapse of the roof of a building housing the headquarters of the Standards Association of Zimbabwe (SAZ). In particular, it examined the prior roles played by the team of construction professionals. The analysis revealed that the SAZ’s traditional construction project was generally characterized by high risk. There was a clear indication of the failure of a contractor and architects in preventing and/or mitigating potential construction problems as alleged by the plaintiff. It was reasonable to conclude that between them the defects should have been detected earlier and rectified in good time before the partial roof failure. It appeared justified for the plaintiff to have brought a negligence claim against both the contractor and the architects. The risk analysis facilitated, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects. It further served to emphasize the point that clients are becoming more demanding, more discerning, and less willing to accept risk without recompense. Clients do not want surprise, and are more likely to engage in litigation when things go wrong.KEY WORDS:Arbitration, claims, construction, contracts, litigation, project and risk The structural design of the reinforced concrete elements was done by consulting engineers Knight Piesold (KP). Quantity surveying services were provided by Hawkins, Leshnick & Bath (HLB). The contract was awarded to Central African Building Corporation (CABCO) who was also responsible for the provision of a specialist roof structure using patented “gang nail” roof trusses. The building construction proceeded to completion and was handed over to the owners on Sept. 12, 1991. The SAZ took effective occupation of the headquarters building without a certificate of occupation. Also, the defects liability period was only three months .The roof structure was in place 10 years before partial failure in December 1999. The building insurance coverage did not cover enough, the City of Harare, a government municipality, issued the certificate of occupation 10 years after occupation, and after partial collapse of the roof .At first the SAZ decided to go to arbitration, but this failed to yield an immediate solution. The SAZ then decided to proceed to litigate in court and to bring a negligence claim against CABCO. The preparation for arbitration was reused for litigation. The SAZ’s quantified losses stood at approximately $ 6 million in Zimbabwe dollars (US $1.2m) .After all parties had examined the facts and evidence before them, it became clear that there was a great probability that the courts might rule that both the architects and the contractor were liable. It was at this stage that the defendants’ lawyers requested that the matter be settled out of court. The plaintiff agreed to this suggestion, with the terms of the settlement kept confidential .The aim of this critical analysis was to analyse the issues surrounding the partial collapse of the roof of the building housing the HQ of Standard Association of Zimbabwe. It examined the prior roles played by the project management function and construction professionals in preventing/mitigating potential construction problems. It further assessed the extent to which the employer/client and parties to a construction contract are able to recover damages under that contract. The main objective of this critical analysis was to identify an effective risk management strategy for future construction projects. The importance of this study is its multidimensional examination approach.Experience suggests that participants in a project are well able to identify risks based on their own experience. The adoption of a risk management approach, based solely in past experience and dependant on judgement, may work reasonably well in a stable low risk environment. It is unlikely to be effective where there is a change. This is because change requires the extrapolation of past experience, which could be misleading. All construction projects are prototypes to some extent and imply change. Change in the construction industry itself suggests that past experience is unlikely tobe sufficient on its own. A structured approach is required. Such a structure can not and must not replace the experience and expertise of the participant. Rather, it brings additional benefits that assist to clarify objectives, identify the nature of the uncertainties, introduces effective communication systems, improves decision-making, introduces effective risk control measures, protects the project objectives and provides knowledge of the risk history .Construction professionals need to know how to balance the contingencies of risk with their specific contractual, financial, operational and organizational requirements. Many construction professionals look at risks in dividually with a myopic lens and do not realize the potential impact that other associated risks may have on their business operations. Using a holistic risk management approach will enable a firm to identify all of the organization’s business risks. This wi ll increase the probability of risk mitigation, with the ultimate goal of total risk elimination .Recommended key construction and risk management strategies for future construction projects have been considered and their explanation follows. J.W. Hinchey stated that there is and can be no ‘best practice’ standard for risk allocation on a high-profile project or for that matter, any project. He said, instead, successful risk management is a mind-set and a process. According to Hinchey, the ideal mind-set is for the parties and their representatives to, first, be intentional about identifying project risks and then to proceed to develop a systematic and comprehensive process for avoiding, mitigating, managing and finally allocating, by contract, those risks in optimum ways for the particular project. This process is said to necessarily begin as a science and ends as an art .According to D. Atkinson, whether contractor, consultant or promoter, the right team needs to be assembled with the relevant multi-disciplinary experience of that particular type of project and its location. This is said to be necessary not only to allow alternative responses to be explored. But also to ensure that the right questions are asked and the major risks identified. Heads of sources of risk are said to be a convenient way of providing a structure for identifying risks to completion of a participant’s part of the project. Effective risk management is said to require amulti-disciplinary approach. Inevitably risk management requires examination of engineering, legal and insurance related solutions .It is stated that the use of analytical techniques based on a statistical approach could be of enormous use in decision making . Many of these techniques are said to be relevant to estimation of the consequences of risk events, and not how allocation of risk is to be achieved. In addition, at the present stage of the development of risk management, Atkinson states that it must be recognized that major decisions will be made that can not be based solely on mathematical analysis. The complexity of construction projects means that the project definition in terms of both physical form and organizational structure will be based on consideration of only a relatively small number of risks . This is said to then allow a general structured approach that can be applied to any construction project to increase the awareness of participants .The new, simplified Construction Design and Management Regulations (CDM Regulations) which came in to force in the UK in April 2007, revised and brought together the existing CDM 1994 and the Construction Health Safety and Welfare (CHSW) Regulations 1996, into a single regulatory package.The new CDM regulations offer an opportunity for a step change in health and safety performance and are used to reemphasize the health, safety and broader business benefits of a well-managed and co-ordinated approach to the management of health and safety in construction. I believe that the development of these skills is imperative to provide the client with the most effective services available, delivering the best value project possible.Construction Management at Risk (CM at Risk), similar to established private sector methods of construction contracting, is gaining popularity in the public sector. It is a process that allows a client to select a construction manager (CM) based on qualifications; make the CM a member of a collaborative project team; centralize responsibility for construction under a single contract; obtain a bonded guaranteed maximum price; produce a more manageable, predictable project; save time and money; and reduce risk for the client, the architect and the CM.CM at Risk, a more professional approach to construction, is taking its place along with design-build, bridging and the more traditional process of design-bid-build as an established method of project delivery.The AE can review the CM’s approach to the work, making helpful recommendations. The CM is allowed to take bids or proposals from subcontractors during completion of contract documents, prior to the guaranteed maximum price (GMP), which reduces the CM’s risk and provides useful input to design. The procedure is more methodical, manageable, predictable and less risky for all.The procurement of construction is also more business-like. Each trade contractor has a fair shot at being the low bidder without fear of bid shopping. Each must deliver the best to get the projec. Competition in the community is more equitable: all subcontractors have a fair shot at the work .A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes. As long as the subcontractors are within the GMP they are reimbursed to the CM, so the CM represents the client in negotiating inevitable changes with subcontractors.There can be similar problems where each party in a project is separately insured. For this reason a move towards project insurance is recommended. The traditional approach reinforces adversarial attitudes, and even provides incentives for people to overlook or conceal risks in an attempt to avoid or transfer responsibility.A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes.

It did appearjustified for the plaintiff to have brought a negligence claim against both the contractor and the architects.In many projects clients do not understand the importance of their role in facilitating cooperation and coordination; the design is prepared without discussion between designers, manufacturers, suppliers and contractors. This means that the designer can not take advantage of suppliers’ or contractors’ knowledge of build ability or maintenance requirements and the impact these have on sustainability, the total cost of ownership or health and safety .This risk analysis was able to facilitate, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects. This work also served to emphasize the point that clients are becoming more demanding, more discerning, and less willing to accept risk without recompense. They do not want surprises, and are more likely to engage in litigation when things go wrong.国际建设工程风险分析摘要此次分析用实例研究方法分析津巴布韦标准协会总部（SAZ）的屋顶部分坍塌的问题。

外文翻译Construction projects, private and public alike, have a long history of cost escalation. Transportation projects, which typically have long lead times between planning and construction, are historically underestimated, as shown through a review of the cost growth experienced with the Holland Tunnel. Approximately 50% of the active large transportation projects in the United States have overrun their initial budgets. A large number of studies and research projects have identified individual factors that lead to increased project cost. Although the factors identified can influence privately funded projects the effects are particularly detrimental to publicly funded projects. The public funds available for a pool of projects are limited and there is a backlog of critical infrastructure needs. Therefore, if any project exceeds its budget other projects are dropped from the program or the scope is reduced to provide the funds necessary to cover the cost growth. Such actions exacerbate the deterioration of a state’s transportation infrastructure. This study is an anthology and categorization of individual cost increase factors that were identified through an in-depth literature review. This categorization of 18 primary factors which impact the cost of all types of construction projects was verified by interviews with over 20 state highway agencies. These factors represent documented causes behind cost escalation problems. Engineers who address these escalation factors when assessing future project cost and who seek to mitigate the influence of these factors can improve the accuracy of their cost estimates and program budgetsHistorically large construction projects have been plagued by cost and schedule overruns Flyvbjerg et al. 2002. In too many cases, the final project cost has been higher than the cost estimates prepared and released during initial planning, preliminary engineering, final design, or even at the start of construction “Mega projects need more study up front to avoid cost overruns.” The ramifica tions of differences between early project cost estimates and bid prices or the final cost of a project can be significant. Over the time span between project initiation concept development and the completion of construction many factors may influence the final project costs. This time span is normally several years in duration but for the highlycomplex and technologically challenging projects it can easily exceed 10 years. Organizations face a major challenge in controlling project budgets over the time span between project initiation and the completion of construction. The development of cost estimates that accurately reflect project scope, economic conditions, and are attuned to community interest and the macroeconomic conditions provide a baseline cost that management can use to impart discipline into the design process. Projects can be delivered on budget but that requires a good starting estimate, an awareness of factors that can cause cost escalation, and project management discipline. When discipline is lacking, significant cost growth on one project can raze the larger program of projects because funds will not be available for future projects that are programmed for constructionA history of past project experiences can serve one well in understanding the challenges of delivering a quality project on budget. Repeatedly, the same problems cause project cost escalation and much wisdom can be gained by studying the past. The Holland Tunnel was, when it opened in 1927, the longest underwater tunnel ever constructed and it was also the first mechanically ventilated underwater tunnel. Its initial cost estimate was made by the renowned civil engineer George Washington Goethals. A review of the Holland Tunnel project serves to highlight the critical issues associated with estimating the costs of large complex projects and the fact that even the most distinguished engineers have trouble assessing cost drivers beyond the physical characteristics of a project. Many times there is no recognition of the cost driver s operating outside the project’s physical configuration. A joint New York and New Jersey commission in 1918 recommended a transportation tunnel under the river “Urges new tunnel under the Hudson.” 1918; “Ask nation to share in tunnel to Jersey.” 1918. The automobile was emerging as the predominate means of transportation and it was decided that this tunnel should be for vehicular traffic. As a result the tunnel would employ new ventilation technologies to purge the exhaust gases produced by the internal combustion engine. Eleven designs were considered for the tunnel, most notably, one by the engineer recently responsible for finishing the Panama Canal, George Washington Goethals. He envisioned a single, bileveltunnel with opposing traffic on each level. Goethals made a planning project cost estimate of $12 million and 3 years for construction. World War I had consumed much of the nation’s steel and iron production, so his design made use of cement blocks as the tunnel’s structural shell. His design was the frontrunning plan “Hudson vehicle tube.” but he had responsibilities elsewhere and was not named chief engineer for the project. Clifford M. Holland was named to head the project along with a board of five consulting engineers “Name interstate tunnel engineers.” 1919. Holland came to the project with vast experience in constructing subways and tunnels in New York. The cost of the project was taken to be $12 million, Goethals’ planning estimate. Holland produced a report in February of 1920 based on his a nalysis of the Goethals’ design of the project. His findings were not what had been expected. Holland found • Goethals’ width of 7.47 m would not accommodate the volume of traffic.• Concrete blocks would not withstand the structural loads exerted on the t unnel.• The construction methods required by Goethals’ design were completely untried.• The estimated cost of construction was grossly low.• The work could not be completed in 3 years.The board of consulting engineers gave unanimous support for Holland’s analysis. Holland then presented a design of his own which was supported unanimously by the consulting engineers. Holland’s design, which was a major scope change, called for twin cast-iron tubes. One advantage was that construction would follow established methods of tunnel construction that had been implemented for rail tunnels under the East River and further up the Hudson. Holland estimated the cost at $28,669,000 “Asks $28,669,000 for Jersey tube.” 1920 and construction time at 31/2 years.Debate about the tunnel design continued for more than a year creating disagreements between the New York and New Jersey Commissions and delaying the work—a schedule change. A disagreement about awarding a contract on the New Jersey side further delayed the start of construction and added over half of a million dollars in cost. Construction started on the New York side in October of 1920 and inlate December 1921 the New Jersey portion of the tunnel was bid “Way all cleared for Jersey tunnel.” The mandated completio n date was December 31, 1926. The construction schedule had now grown to 5 years. Estimated project cost increased multiple times throughout the early years of construction as a result of scope creep, schedule delays, and inflation. Increased traffic forecast necessitate larger entrance/exit plazas and acquisition of more right of way “Vehicular tube is growing.” 1923. Then increases in material and labor costs had added another $6 million to the project inflation. By the beginning of 1924, reestimated costs had been increased by $14,000,000 “Vehicular tunnel cost up $14,000,000.” 1924 due to functional and aesthetic factors scope creep. More intricate roadway designs for approaches, widening of the approach roadways, and architectural treatments increased the costs more scope creep. Redesign of the ventilation system added 15.24 cm to the tunnel diameter and $4,422,000. Holland also decided to substitute cast-steel for castiron to increase the strength and safety factors of the tunnel more scope creep. Last, the New Jersey ventilation shafts had to be redesigned along with their corresponding foundations at a cost of $700,000 due to unexpected soil conditions unforeseen conditions. All of these changes increased the estimate to over $42.5 million. New funds were appropriated and it was believed that these were sufficient to complete the project, but by February of 1926, there was another increase of $3,200,000 “$3,200,000 more asked for tunnel.” The commission explained that the new costs were due to increases in labor and material costs challenge in controlling cost. At this time Holland died of heart failure and his assistant, Milton H. Freeman, took over as chief engineer only to die of pneumonia 4 months later. Ole Singstad, the designer of the ventilation system then became chief engineer and brought the project to completion. Having three different chief engineers within 5 months created confusion unforeseen events. In April of 1924 water rushed into one of the tunnels from a leak forcing workers to make a hasty escape more unforeseen conditions. A final appropriation was requested in early 1927 brought the total project cost to $48,400,000. On November 13 of 1927 the tunnel officially opened “Work on tunnel began 7 years ago.” MethodologyThe cost escalation factors that lead to project cost growth have been documented through a large number of studies. Studies have identified factors individually or by groups. Each factor presents a challenge to an agency seeking to produce accurate project cost estimates. As part of a larger study seeking to improve cost estimates and management of costs from project conception to bid day, a thorough literature review was conducted to identify factors that influence cost estimates Anderson et al. 2006. The literature review included exploration of research reports and publications, government reports, news articles, and other published sources. Upon completion of the literature review the factors were analyzed and categorized by the researchers into factors that drive the cost increases experienced by transportation construction projects. This was accomplished by triangulation where multiple investigators or data sources suggested the same factor. This categorization took the individual factors which had been identified in previous research and established a global framework for addressing the issue of project cost escalation. Upon final categorization the cost escalation factor framework was verified through triangulation of data from interviews with more than 20 state highway agencies SHAs around the nation . A previous project that supported identification of the factors had included telephone interviews with all 50 SHAs Schexnayder et al. 2003 . An interview instrument was prepared and tested initially during onsite interview with two SHAs. The revised interview instrument was then sent to the SHAs before the interview so that they could prepare. The interviews were conducted onsite for five SHAs through individual interviews and through a group “peer exchange.” The remaining interviews were conducted by telephone. In all cases, the researchers followed the interview protocol to ensure consistency in data collection. The resulting categorization of cost escalation factors can help project owners and engineering professionals focus their attention on the critical issues that lead to cost estimation inaccuracy.The triangulation analysis considered methodologies from past studies and interviews to create a categorization for the causes of cost escalation. A better understanding of the cost escalation factors is achieved through understanding theforces driving each factor or where the factor originates. With this understanding it is possible to design strategies for dealing with these cost escalation factors. The factors that affect the estimate in each project development phase are by nature internal and external. Factors that contribute to cost escalation and are controllable by the agency/owner are internal, while factors existing outside the direct control of the agency/owner are classified as external. The presentation order of the factors should not be taken as suggesting a level of influence is constructed to provide an over arching summary of the factors. It summarizes the factors into logical divisions and classifications and helps in visualizing how project cost estimates are affected. It is important to note that one of the factors points to problems with estimation of labor and material cost, but most of the factors point to “influences” that impact project scope and timing.中文译文私人和公共的建设项目，一直以来有成本增长的问题。
