工程造价毕业设计外文文献及译文外文文献:Construction Standards and CostsUC Irvine new construction pursues performance goals and applies quality standards that affect the costs of capital projects. 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。

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.

Control project cost effectively, in the early phase of the project shall be subject to supervision (including cost management ) system. Through analyzing the design process of supervision, make the design more reasonable, cost control to limit the scope of, accomplish truly with the smallest investment maximize output.Strict supervision system.

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。

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 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 asoverheads, 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. 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 themdownwards. 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 different corporate production divisions are involved, there may be a further intermediate step of creating "Control Accounts" for theseparate 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 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 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 changesthe project's Approved Project Budget.• Now, as the work progresses, you can plot the "Actual Cost of Work Performed" (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。

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

2.2.1 政府直接调控
考虑到配额的发展历程,可以发现,配额应运而生,发展,成为中华人民共和国的 成立后计划经济的发展逐渐成熟。自从中国进行了投资系统集中管理模式,很长一 段时间,政府不仅是宏观政策的厂商,但微型项目建设的参与者。因此,计划经济 的色彩密集统一的配额能够提供强大的方法和手段,为政府进行宏观投资调控和微 观建设项目管理。
1)项目招标的影响。 招标可以确定价格中标, 而被价格的基础中标确定的合同价格。 如果出现错招投标,那么它可能会导致价格招标的失真,这是不可能提供成本控制 准确,可靠的基础,甚至导致过度的成本失去控制。
2)合同签订和管理的影响。合同价的确定进一步使得成本控制的精确的目标,以及 对合同条款的初步草案规定的成本控制基础上正确和原则。合同签订后,合同项目 被视为基础,这将有超过设计变更严格的合同控制在施工阶段,工程测量,支付建 设的债务,与建设补偿等,这将确保实现控制的目标。因此,失去控制权合同签订
2.4 在施工过程中的成本控制
建设项目的实施阶段,是一个需要在项目建设全过程的大部分资产,也是一个重要 的舞台,金钱资源转化为建筑实体的阶段。在实施阶段的成本控制是指通过在确保 工程质量和工期的条件了科学的成本控制理论和方法来限制调度的控制范围内的建 设成本。代建筑物实体的过程是不可逆的,所以如果有效的自动控制和预控不能通 过建设成本来进行,则经济损失可能会造成无法弥补。
2.2.3 当前建设成本估价模型
估值模型是工程造价管理的一个基本方面。工程造价管理是政府行为,而估值模型 是一个国家的手段来管理和控制建设成本。目前有两个中国建筑估值模型,即根据 定额计价模式和一个根据法案的数量。
2.2.3.1 根据配额估值模型 根据定额计价模式是在从计划经济向市场经济的过渡时期采取的有效模式。根据配 额通过估值模型工程造价的确定防止高估的估值和收购标准,价格压到一定程度, 由于预算定额标准化的消费率和各种文件规定的人力,物力,设备单价和各种服务 费规范,这反映了规范性,统一性和建设成本的合理性。然而,它具有在市场竞争 中抑制效果,是不利于的建筑企业,以提高其技术,加强其管理和提高其劳动效率 和市场竞争力。
2.5 在实施阶段影响工程造价的主要因素分析
项目的实施阶段是指从施工图设计和审查,并提交完成的时期到建设方到最终竣工 验收的项目,直到它被投入使用。根据建设项目的实施阶段的基本操作流程,形成 了建设成本要经历这样大的方面如招投标,合同签订和管理,一个施工图联合审核, 施工管理计划的调查,物资管理和竣工结算等。所有这些方面影响施工费用结算程 度不同。在这个过程中,从预算价格,价格不断变化的成功竞标,对于合同整修费 用后,建设成本最终在结算价项目完成的形式来确定。影响施工成本因素是多方面 的,但是从成本形成分析的角度来看,有主要理由如下。
方法主要是控制结算及施工成本,这仅仅是事后算账的方法的改变,并不能满足节 约资源,提高工作的目的。近年来,发达国家对项目投资的要求已经提前计划来控 制,并在一个事件,其效果已被证明是有效的中间控制。实际上一个科学的方法应 该是,施工成本控制的方法和事前事后可以消除或徒劳或低效率和不必要的资源退 化和方法之前或在事件发生后实施建设项目的应用减少劳动力。
本文旨在分析在通过理论方法和施工成本管理的实践研究整个工期成本控制存在的 问题。特别是,在建设前期的成本控制问题值得我们的研究,使我们可以探索相应 的改革措施,以提供施工项目成本控制提供一些参考。
其中概算超过估计的建设项目的情况下,预算超概算,结算超预算,是在中国固定 资产投资的一种普遍现象。这是失控的建设成本增加了投资的压力,增加了建设成 本,减少投资收益,影响投资决策,而且,在很大程度上,浪费国家财政,所以很 容易导致腐败行为或违法行为。 20 世纪 50 年代以来的中间,总结基本建设战线几 十年的实践经验的基础上, 我们进行了一系列的工程建设领域的改革。 特别是自 1988 年 5 月,我们已逐步实施建设监理制度在全国各地,这已经在逆转失去在执行期间 建设项目的控制权的现象一定的积极作用。然而,由于该系统仍处于起步阶段,还 没有出现大批的专业和社会监督队伍。此外,在其施工监理进行的项目,存在着普 遍现象,如监督和经济方面忽视的技术问题“,在施工阶段强调质量控制和投资控 制的忽视”和“重点监管“。在现实中,监管的权利往往被局限在技术方面的管理, 而经济方面的管理是牢牢地掌握在所有者的控制权。同时,滞后现有工程造价管理 体系的后面为失去建设成本控制的主要原因。因此,作为一个整体,在建设工程造 价失控的现象还相当严重,因此有必要进行进一步的研究,并就目前的建设成本管 理和因素的主要因素进一步分析在建设项目的所有阶段的影响施工成本。
考虑到上述情况,学术界提出了成本管理,早在 20 世纪 80 年代的全过程控制的理 念。他们开始重视建设项目前期管理和主动进行成本管理。随后,于 2003 年 7 月 1 日,实施 <<成本估算为规范建设工程工程量清单 >>的象征,中国的成本估算已进入 一个崭新的新时代,随着市场经济的发展规则的情况。从那时起,概念和中国成本 管理的方法被确实与国际社会一体化。
2)研究和分析现状和目前的建设成本管理存在的问题,并在确定和施工成本控制研 究这些问题的影响。
3)提出了有效的途径和方法,从决策阶段的建设项目的价值工程良好的应用,设计 阶段,施工阶段,施工阶段的竣工验收。
4)要明确意义,必要性和建设项目成本控制的可行性,为改善中国的工程造价管理 提供建议。

3)施工管理检查计划的影响。施工管理计划是用于确定项目招投标价格和合同价格 重要基础之一。在施工过程中,合同价格的调整也应根据施工组织设计确定的,因 为施工组织设计的好坏将直接影响项目的质量和进度。因此,失去控制施工管理检 查计划将在超过建设成本的控制带来极为不利的影响。
2.2.3.2 根据工程量清单计价模型
根据工程量清单计价模式是最近提出的建设成本确定模式。在这种模式下,政府仅 仅是统一项目编码,项目名称,数量的测量和测量规则的单位。各施工企业都有自
决权根据要约自身情况来报出的价格,并在招标的过程中由此形成的建筑产品价格。
2.3 在实施过程中成本控制
长期以来,技术,经济一直在工程建设领域分开。由计划经济体制的约束,有没有 在我们的工程师和技术人员的头脑经济的概念,因为他们认为降低建设成本,作为 财务人员的责任:在没有做自己。然而,金融和初步预算人员的主要职责是按照财 务制度行事。通常情况下,他们不熟悉施工工艺,并了解项目的设计,建设内容及 实施建设的各个关系的变化很少,甚至没有。在这种情况下,他们别无选择,只能 机械地锻炼身体,或从财务角度看,这会导致技术和经济的相互分离的审计费用。 他们只是做他们做什么,这反映了不利已完成一期工程量的价格,因此很难合理有 效地控制建设成本。
2. 初步ห้องสมุดไป่ตู้究内容
针对目前的“建设工程造价的全过程控制”的主题,并根据大量的有关决定,并在 国内和国外施工项目成本控制的文献综述,本文的作者收集了大量了一些有关省, 经过调查城市的报告和数据。随后,笔者进行了以下工作。
1)分析建设项目投资的制定和找出在建设项目的所有阶段失去对施工成本控制的主 要原因。
失去了建设项目投资控制是中国固定投资领域的一个普遍现象。建设项目消耗了相 当多的人力,物力和机器,具有投资大,建设周期长,以及强大的合成,因此它与 所有政党建设的经济利益相关的,意味着很多国家经济。目前,在中国工程建设领 域,存在技术和经济分离的现状。大多数工程师和技术人员往往把建设成本融资和 初步预算人员的责任,并错误地认为它无关的自己。在开展项目的过程中,他们通 常只专注于质量控制和进度控制,而忽视了在建项目的投资控制。如果技术人员忽 视建设成本,和那些谁是负责建设成本都在建设成本连接相关的技术建设无知识, 那么就很难让他们合理确定和有效控制工程造价。施工监理投资控制是指管理活动 的项目,它试图以确保实现项目的投资目标提供满意的质量和进度的前提下,实现 整个国家。投资目标设定为通过项目建设的全过程建设实践的进一步进展,施工成 本控制运行的不同阶段,但它应该到的关键点突出。显然,建设成本控制的关键在 于投资决策和设计阶段施工前,而投资决策作出后,关键在于设计。建设项目的生 命周期包括建设成本和之后的建设项目投入使用的经常性开支,并丢弃和拆卸费用 等项目的使用期。据一些西方国家的分析,通常设计成本仅为达建设项目生命周期 的不到 1%。然而,它是该占建设成本影响超过 75%的小于 1%的成本。因此,显然 的是,设计质量是整个项目建设的好处是至关重要的。
