工程造价管理与投资控制综述182020年5月29日文档仅供参考工程项目建设的中心任务就是实现项目目标。从客观意义上讲,投资目标的实现才是业主经济效益的真正体现;而工程造价的确定与投资的有效控制是工程建设管理不可缺少的重要组成部分,在项目建设管理中有着特殊的地位。随着中国经济体制改革的不断深入,国民经济持续发展,怎样加强工程造价管理,提高项目投资效益?这是当前投资和造价改革的一个重大课题。造价和投资在国民经济发展中和社会经济活动中,有很多一致的地方,但不是一个等同的概念。从目的来看,搞好投资是为了使投下去的一定量的货币能保证回流,并实现增值;而搞好造价是为了使投资项目的工程价格水平控制在目标额度之内;从行为过程来看,投资的行为过程是资金投入+项目实施+项目控制+资金回收,造价的行为过程是造价确定(包括投资估算、设计概算、施工图预算)+过程控制+竣工决算。投资的行为过程比造价的行为过程更长。同是资金运作过程,造价是使货币资金转化为实现目标额度内的资产,而投资是使货币资金转化为资产,并经过资产的使用又使货币资金回流。造价是投资的一个关键部分和主要内容,它包括建设工程从建设筹备到竣工验收所需费用的总和,它由建筑安装工程费、设备工具购置费、工程建设其它费用、预备费、建设期贷款利息、固定资产投资方向调节税和铺底流动资金等项组成。价格机制是造价管理的核心问题,也是投资宏观决策和提高项目投资效益的一个核心问题。要加强造价管理,提高投资效益,必须形成一个国家宏观调控下,以市场形成造价为主的价格机制。传统的预算定额制度在计划经济体制下,对加强计划管理,减少投资浪费等方面起到了一定的积极作用。但随着社会主义市场经济的逐步建立和发展,现行预算定额制度与之越来越不相适应:定额中”量”和”价”没有分开,形成了”活市场”和”死单价”的矛盾,不能在市场中真实地、及时地、准确地反映建筑产品的造价;现行预算定额中综合程度较大,施工手段消耗部分统得较死,构成工程实体消耗部分是由设计决定的,而施工消耗部分,如脚手方案、垂直运输等内容应由施工企业在确保全面履行合同的前提下自行决定,现行定额中,把本应属于竞争的内容凝固化了,不利于施工企业发挥优势,竞争取胜;现行预算定额带有法定性质和强制性质,对预算定额直接费的取费标准,开发商和承包商都不得随意改变,还是计划定价为主;现行预算定额计价主要由直接费、间接费、独立费、利润和税金构成,除直接费外其余各项都以取费率的形式出现,取费固定化,不利于直观地反映各项工程内容的价格,并与国际报价方式差距也较大。为了有利于投资宏观决策和提高项目的投资效益,必须把计划形成工程造价的价格机制,改为国家宏观调控下以市场形成工程造价为主的价格机制,也就是要在统一工程量计算规则和社会平均实物消耗量定额的基础上,遵循商品经济价格规律,建立以市场形成造价为主的价格机制:一是全面实现”量价分离”。把政府发布量价合一的预算定额制度,改为政府发布工程消耗量定额,单价随行就市,变当前发布指导价要大家执行改为发布市场信息价进行指导,从而使不断变化的价格同相对稳定的实物消耗量相分离;二是统一工程量计算规则。要逐步按照国际习惯,统一工程量名称、计量单位、计算规则、项目编号等,既有利于指导市场,又有利于同国际接轨;三是将工程实体消耗和非实体消耗(施工措施性消耗)相对分开。这有利于承包商发挥各自优势,竞争取胜;四是简化繁琐取费。现行定额中各子目的造价不能直接反映,必须重新计算取费后才能明了,各子目、各分项工程的造价与总价的关系模糊,简化取费后,各分项及子目的造价与总价的关系变得清晰,有利于投资控制活动和分包及设计变更部分的计价;五是保留政府对重要生产要素价格进行干预的权力。如对市场某种资源紧缺时实行最高限价,规定最低日工资水平和部分工种最高日工资限价等。造价确定与投资控制贯穿项目建设全过程,而对项目投资影响最大的设计阶段。在建设项目的整个寿命期内,项目的初步设计基本上决定了建设项目的规模、结构形式、建筑标准和使用功能,形成了设计概算,确定了投资的最高限额。施工图设计完成后,编制出施工图预算,准确地计算出建设工程造价。因此,工程设计是影响和控制建设工程造价的关键环节和重要阶段。长期以来,我们在工程造价管理中,普遍忽视设计阶段项目的投资控制,而往往把控制项目投资和工程造价的重点放在实施阶段,投入了大量的人力、物力去审查或计算建筑安装工程造价,很少考虑如何才能达到投入合理的资金,获得美观大方、功能齐全适用、经济合理的建筑产品。根据国内外有关的统计资料表明:初步设计阶段影响工程投资数额幅度的可能性为7090%,在技术设计阶段(施工图设计)影响投资的可能性为3075%;在施工阶段(实施阶段)的影响工程投资的可能性为5%25%。或者具体地说,设计阶段影响工程投资的可能性为80%,而实施阶段影响投资的可能性,充其量不会超过20%,即经过各种措施降低成本最大限度不外乎为20%以下。一般情况下设计图纸一旦完成,”按图施工”就是施工企业必须履行的原则,施工企业无权随意变动图纸,也没有时间精力及承担风险地去考虑优化设计。而中国普遍存在着设计部门比较保守,有的设计只图方便、凭经验而不作方案对比,甚至盲目追求安全度和设计收费,而至关重要的概预算控制则与设计院利益无关甚至违反,因此无从控制。工程设计和工程造价原来应该是统一整体的相互配合、配合促进的两项工作,而在我们的实际工作中,却如不同道路上奔驰的两辆汽车,各行其道,互不关联。设计部门只管设计质量,一般不论工程造价的高低,给国家的建设资金造成了极大的浪费。要改变这种不良局面,在设计阶段,必须加强工程造价和设计之间的横向联合,推行限额设计,逐步实行以”价”定”量”的设计方法,在项目的投资范围内,按照”安全”经济”适用”节俭”的原则进行工程设计,促使设计人员精打细算,精心设计,达到在设计阶段有效控制工程造价的目的;要优化设计方案,其目的就是论证拟采用的设计方案技术上是否可行、功能上能否满足需要、经济上是否合理、使用上是否安全可靠。特别是在经济上,设计的优化是很重要的控制手段,新工艺的使用、新材料的投入、一些局部设计的改变等,这些因素的变化,往往使工程造价大幅度增减。据研究资料显示,建设项目的建筑系灵敏、空间平面、层数和层高、结构和材料的选择、设计的选型等因素,直接影响着工程造价的高低。因此,要想在设计阶段控制工程造价,就一定要做好设计的优选工作,在设计阶段进行设计招投标和设计方案的竞选,并运用价值工程等手段对备选方案进行优化,还要进行设计方案的技术经济评价,真正达到以最优的设计、最经济的投资,建造最好的工程项目的目的。建设工程造价全过程控制,是工程造价管理的主要表现形式,是提高项目投资效益的关键所在,它贯穿于决策评估阶段、设计阶段、工程承发包阶段、施工实施阶段、竣工验收阶段等项目建设全过程。科学周密而有计划地分阶段设置投资控制目标,能够经过目标控制,在项目投资决策、设计、发包和实施阶段,把投资发生额控制在批准的限额以内并随时纠编,确保投资目标顺利实现,使投资估算、工程概算、设计预算、承包合同价更趋合理准确,真实而客观反映项目实际进程发生额,有效防止概算超估算、预算超概算、竣工结算超预算这一”三超”现象的发生,最大程度地合理使用人力、物力、财力,从而取得较好的投资效益和社会效益。Shallow engineering cost management and investment controlProject construction central task is to realize the project goals. From the objective sense, investment to achieve the goal of economic benefit is owner real embodiment, And project cost determination and investment of effective control of the engineering construction management is an important and indispensable part of project management has a special position. As Chinas economic system reform, the national economy continues to develop, how to strengthen the engineering cost management, improve the project investment benefit? This is what the current investment and cost reform a major issue.Cost and investment in the development of national economy and social economic activities, have a lot of consistent place, but not a concept equivalent. Judging from the purpose is to make the investment, improve the amount of cast currency can guarantee, and realize value-added backflow, And improve cost is to make the investment project engineering price level control at target within the quota, Judging from behavioral process, investment behavior process is capital investment + project implementation project control + capital recycling, the cost of the behavior process is cost sure (including investment estimation, design budgetary estimate and construction drawing budget) + process control + the final accounts of the completed project. Investment behavior process than the cost of behavioral process longer. With the operation process, cost of capital is make monetary fund transform for achieving goals within the line of assets, investment is make monetary fund transform for assets, and through the use of assets and monetary fund backflow.Investment cost is a critical part of and main content, it includes the construction project from construction preparatory to completion acceptance of the cost of combined, and it consists of building the cost, equipment tools is, the engineering construction other fees, reserve, interest interest, tax for fixed assets investment and the current funds and so on a composition. The price mechanism is the core of cost management in the problem, but also investment macro decision and improves the project investment benefit of a central issue. To strengthen the cost management, increase the investment effects, must form a under the states macroeconomic control, taking market mainly formed cost price mechanism.The traditional budget norm system under the planned economy system, to strengthen the investment plan management, reduce waste aspects have certain positive role. But with the socialist market economy is gradually establish and develop the current budget norm system and the increasingly does not adapt: quota of quantity and price no separate, and formed a living market and dead unit price, the conflict cant in the market truly, promptly and accurately reflecting the cost of building products, The current budget ration of comprehensive degree bigger, construction means consume part is dead, stockings constitute engineering entity consumption part is decided, and by the design of construction cost parts, such as feet hand scheme, the content such as vertical transportation should be by construction enterprise in ensuring allround to perform the contract under the premise of themselves, the current norm, should belong to the contents of the NingGuHua competition, to the detriment of construction enterprise and advantage, competition to win; The current budget norm with legal nature and forced properties of budget ration direct fee fees standard, developers and contractors are altered arbitrarily, or planned pricing for the Lord; The current budget quota valuation mainly by direct fee, indirect fee, independent fee, profit and taxes constitute, in addition to direct fee to take everything correctly outside the rest rates form, and fees immobilized, go against intuitivey reflect the project content price, and with the international quoted price way gap bigger also.In order to which investment macro decision and improve the benefit of investment project, must the plan formation of engineering cost price mechanism, instead of under the states macroeconomic control by market mainly formed engineering cost price mechanism, was also must in unity quantity calculation rules and social average real consumption quota, follow the commodity economy based on the law of value, establishment of market mainly formed cost price mechanism: one is to fully realize price volume separation. The government issued the unity of quantity and price budget norm system, instead of the government issued engineering consumption quota, unit price for seven, become currently issued guided prices wants everyone to execute instead released market information, thus making the price guidance to the price of changing with relatively stable physical consumption phase separation, 2 it is unified quantity calculation rules. Will gradually according to international habit, unified quantities name, unit of measurement, calculation rules, project Numbers is not only beneficial to the market for guidance, etc, but also with the international community, Three is to engineering entity consumption and non entity consumption (construction measure sex consume) relative apart. This is helpful to the contractor play to their respective advantages, competition to win; The fourth is simplified trival fees. The current norm of each ZiMu cost cannot directly reflect, must recalculate fees can be known, ZiMu after each and every item construction cost of the total value of the relationship with fuzzy, simplify the fare, each partial and ZiMu cost and price relationship became clear, which investment control activities and subcontractor and design the variation valuation, Five is reserved to the government of important factors of production price intervention power. As to the market some resources when the highest price fixing, fixing minimum daily wages level and some type of highest daily wages limit etc.Cost determination and investment control throughout the whole project construction, project investment that has the largest effect on stage of design. In construction projects on the life period, preliminary design of the project of construction project basically decided the scale, structure, construction standards and use function, formed design budgetary estimate, determine the investment ceiling. After the completion of the construction drawing design, formulate construction drawing budget, accurately calculate construction engineering cost. Therefore, engineering design is to influence and control of construction engineering cost of key sectors and an important stage.For a long time, we in the construction cost management, ignored in common design phase project of investment control, and often take control project investment and project cost focuses on the implementation stage, put in a great deal of manpower and material resources to review or computing architecture installation project cost, seldom consider how to reach into reasonable fund, acquire beautiful generous, complete functions applicable, reasonable economy construction products. According to the domestic and foreign relevant statistics show that the preliminary design stage affected the project investment amount the amplitude of the possibility for 70-90 percent, in the technical design stage (construction design) affect investment possibilities for 30-75%, During the project construction phase (the implementation stage effect of project investment possibilities for 5% - 25%. Or specifically, design phase affect the project investment possibility to 80%, and the possibility of the implementation stage affect investment, at best not exceed 20%, namely through various measures to reduce cost utmost nothing more than 20 per cent for the following. Normally design drawings once completed, according to drawing construction is the principle of construction enterprise must perform, construction enterprises shall not be entitled to optional change drawings, also have no time, energy and take risks to consider optimization design. And our country there are generally design department conservative, some design only figure convenient, with experience without scheme contrast, even blind pursue safety and design fees, and budget control is vital interests with the design institute has nothing to do, so dont even break the control.Engineering design and project cost is supposed to be a unified whole of mutual coordination and cooperation to promote the two tasks, and in our practice, but like a different path Benz two car, village populated, without relevance. Design department; the design quality and general regardless of engineering cost, or to the construction of the country caused a great waste of money. To change this situation, adverse in the design stage, we must strengthen the construction cost and design between horizontal cooperation, promote design-limited, gradually executed with price fixed quantity design methods, in the project investment scope, according to safe economy application frugal principle for engineering design, prompting designers have carefully, elaborate design, achieve in the design stage effective control of the project cost purpose; To optimize the design of argumentation, the purpose of which is to adopt the design scheme is it technically feasible, function can satisfy the need, economically whether reasonable, whether using on safety and reliability. Especially in economy, design optimization is important means of control, a new process of use, new material of dedication, some local design change etc, these factors change, often make engineering cost greatly increase or decrease. According to research data shows, the department of construction project is sensitive, space layout, layer number and layer are tall, structure and the choice of materials, design of the selection of the factors, the direct impact on the discretion of the engineering cost. So, want to control the engineering cost in the design phase, she will do it well design optimization of work, in the design stage design bidding and the design scheme of the campaign, and use of value engineering means of alternatives to optimize design scheme, which will be the technical and economic evaluation, achieve true with optimal design, the most economic investment, to build the best project purposes.Construction engineering cost control process, is project cost management is the main form, is to improve the project investment benefit is the key, it is perforative in decision evaluation phase, design phase, project contracting stage, construction implementation stage, such as the completion acceptance stage project construction process. Scientific subtle and systematically stages setup investment control target, can pass aim control, in the project investment decision-making, design, and implementation stage, the out-contracting investment amount control before the approved limits and to rectify within ed., ensure investment target smooth realization and make investment estimation, project budget, contracting estimates, the design contract price more reasonable accurate, real and reflect the objective project reality, effectively preventing the budget process amount exceeds the estimation, the budget exceeds the budget estimates, the completion of this settlement SanChao phenomenal happening, to the greatest extent reasonably using human, material and financial resources, thus achieve better investment benefit and social benefit.
