The significance of control construction costs manages on entire process

First，The necessary of control construction costs manages on entire process
Talk about the management and the control on construction costs， that the field we are just accustomed to is thought of is a project advance in final account. Indeed ，right away at present system and reality,what the job of that the management and the control on construction costs is advance in final account. Be that in advance，the people who work on final account according that already be ascertaied of the working drawing to calculate project amounts，apply a quota mechanically， the meter mechanically fetching cost，or designing that according to the drawing sheet and construction organization after construction is over as well as the scene construction visa takes notes weaves the final account being completed. This is necessary ，useful no doubt. But we must see that when pre-final accounts personnel weave working drawing budget or the final account being completed，the construction plan and the design paper already determined. But construction being to take according to picture as principle，so then in advance，job done by final account personnel is only the change secretly scheming against cost produced by design alteration and prevents upvaluation from calculating boldly. But suppose the project is unreasonable on economy，there is a fault in decision-making；suppose designing a scheme feasible or be not optimum on the technology；the final account personnel can do nothing for sb then in advance. Job of final account personnel does accounts in advance only under just saying system currently in effect，after the event ，can only reflect already complete project amounts inactively ，can only reflect design and be under construction passively. This evidently is single-faceted ，insufficient ，we must carry out the entire proceeding supervisory control on the construction costs of building a project.
Concrete conditions of union our country，cost of construction manages have problems as follows:
1、Be not enough to take investment decision into the stage of construction costs seriously charge indeed.
Investment decision is to produce the construction costs headstream，This one stage blow the expense at take up the total investment forehead about 0.5%～3%,but that can have an effect to raise the project benefit of investment. That the project carries out rational choice on construction is that resource carries out direct ，the most important optimization deploy means on economy ，project benefit of investment affects efficiency and beneficial result to entire national economy. The developed country charges attach importance to control on investment decision stage construction costs,and costs not stinting big capital of money making the studies on the stage of carrying out investment decision energetically，make relatively comparatively accurate construction costs ，go along the control
For a long time，there is the grave phenomenon investing in swelling in engineering construction of our country,bring the limit for a project feeling longer and longer，construction costs is higher and higher. The cause of that is short of the effective basis of the building of earlier stage ascertaining construction costs，only basis the already completed according to the expert ，decision-makers draw lessons to estimate the project construction costs. Because a lot of factor effects，the“three surpass " phenomenon very common，there are main cause as follows:
(1) personal factor brings about rough estimate lessening
(2) equipment composes in reply material price's not working out according to market quotations.
(3) construction units bring forward the too high for exceeding a design criterion
2、The design stage of construction costs is not under the control of strict
The design stage is the faucet in that project construction costs controls. After the investment decision is be made rationally ，that is the process of plan the technology and organic together economly . Effective control the cost of construction requires strictly and all-round in the enginee designing . Engineering design of current our country also puts move bidding system ，fair competition into practice ，cost of construction looks on control engineering effective to design stage as one of the standard choosing main part being hit by the bid unit ，cost of construction carries out the administration controlling on the entire proceeding .Our country major part design that the unit carries out thorough analysis lack on construction project technology and economy ，big multiple technologies make light of economy in design but at present ，design that the personnel is responsible seemingly only to design project mass ，are concerned with the construction costs height not very. Optimize a design plan to such an extent as having no way to pass，the first step designs ，the rough estimate gets to the effect controlling general cost of construction's establishment. Mass and depth that engineering design pursues etc. is also insufficient ，amounts project mistakes in amounts project detailed lists calculates ，misses and not calculating，can't arouse increasing by estimating a project momentary，the mass making a tender work is difficult to ensure that ，have no way to have an effect to control construction costs as a result also.
3、Has not adopt the amounts project detailed list quoted price way being applied or used universally on the international all round
Adopt the amounts project detailed list quoted price way being put into use commonly on the international ，is that our country construction costs system reforms and cause the inevitable trend reforming to bid system in invitation to bid tender.
One of important act carrying out project public bidding system being to build socialist market economy and to perfect construction market operating mechanism in construction field. After the construction project tender is carried out all round in our country，the effect is obvious in the respect of shortening the mass building a time limit for a project ，ensuring a project ，reducing construction costs ，boycotting an unhealthy tendency. Have ensured the invitation to bid people and bidder's lawful rights and interests also effectively. With the socialist market economy uninterrupted growth,the original tender stage puts the budget quota valuation pattern into practice already doing not adapting ，adopt the amounts project detailed list quoted price way being put into use commonly on the international to carry out a tender is an inevitable trend. Ministry of Construction has issued amounts project detailed list valuation method ，amounts project detailed list valuation has been in construction project tender job ，person has provided project quantity from invitation to bid according to national unification project amounts calculation regulation ，quoted price，and classics have judged the reason bidder autonomously trying the at a low price middle bid construction costs valuation pattern.
That carrying out amounts project detailed list valuation method is one important measure of item of construction costs deepen the reform，is standard tender behavior effective measure. This method is beneficial to changing over taking that "amounts" "，"price" are "quota-consuming" as dominant static state managing a pattern ，make project amounts in detailed list not enter competition，competition being confined to price only；Beneficial to rightness appraises enterprise strength；Project mass beneficial to ensuring that，reduces construction costs；May cut down the physical labour complicated and overloaded repeating the amounts calculating a project；Facilitate the tender quoted price job；Argue with the dispute back and forth in cutting down project settlement；Receive a track step by step with the convention "controlling amounts ，guiding price ，competing for a fee's on" the international，deepen the reformation that project valuation manages mainly according to the marketplace changes development，taking one's place on the international market for our country contracts business creates condition.
4、The stage being under construction controls lack to construction costs
Want to have strict control design alteration too in the stage being under construction. Guard the pass though that working drawing appears in joint trial or are able to have all sorts of problems，but call for to design a branch in the process of construction hard to avoid is strict out of the construction works complexity，the situation changing after avoiding doing first，is also that the weight avoiding break a rough estimate ，effective control engineering of construction costs cost of construction plays with a link. At the same time，the sharpening contract manages ，ensures equality and mutual benefit issuing contract of method and contracting method.
5、The construction costs being completed settling a stage's controls a project inefficiently
That the final account being completed is that entire construction costs is under the control of the most important one is encircled by construction works. How the final account being completed can reflect actual entire project cost of construction honestly ，have also reflected the ability issuing contract of method and contracting method to construction costs administration ，have finished handling a project in time the final account being completed must collect ，arrange settling a data ，pursuing ，designing the certificate material changing notice ，various warning including that the project is completed and so on being completed. These data collecting must pay attention to whose validity with obtaining evidence，specimen seal impression having designing personnel's signature and being related to if the design alteration advice note must be made known to lower levels by plain design organ. Scene inspection and control visa must label seal and the ratification going on a punitive expedition to such that designing a personnel etc. having construction site person in charge of first party. Great majority our country construction projects are completed in the project being under construction when the final account，during the period of the final account being completed contracting method ，are are under construction contracting method calculating commonly much in the book being completed winding up an account ，are issue contract of haggie just inexhaustible in devices and schemes ，are dispute over trifles phenomenon is grave ，project settlement drags repeatedly ，some confirmation having drug once and ，greatly，affecting engineering construction project sigmatism and building construction costs.
A construction project includes the following procedure from brewing ，planning ，designing that to establishing completion and commissioning：Be that the project letter of advice stage ，feasibility appraise the stage ，design stage ，the stage being under construction ，acceptance check stage and the queen being completed estimate that. Correspondingly，the construction costs ascertaining that and the project construction phase job look at and appraise the stage adapting to ，several being allotted in general for the following：The investment studying stage establishment in the project letter of advice and feasibility is estimated，design stage establishment designs a rough estimate in the first step，budget designing that the stage weaves working drawing in working drawing，budget builds ampere of construction costs face to face with working drawing for basis tender project engineering contract，price is also that the form ascertains that with the business contract；Project amounts putting stage into practice being going to be completed according to contracting reality in project，takes contract price as basis ，considers cost of construction rise aroused by inflation of prices at the same time ，considers the project and cost being difficult to estimate that to designing middle but happening in putting stage reality into practice ，the example is ascertained estimating price；All-in cost costing in the reality being completed checking and accepting a stage ，assembling into engineering construction process middle all round，weaves the final account being completed ，embodies the actual cost of construction that a construction project according to the facts.
"Four guess that two-valence "is interrelated ，the former restricts the latter ，the latter supplements the former.
What is called，build the construction costs administration and control，it is the occurrence contracting the stage and construction in the investment decision stage ，design stage ，construction project putting stage into practice with construction construction costs to control within the cost of construction quota O. K. ，correcting the deviation happening at any time，to ensure that the project manages the target realization ，get fairly good benefit of investment and social benefits in an attempt being able to use manpower and material resources，financial resources rationally in building a project one by one.
Second，the importance of the investment decision-making stage of project cost control
Construction projects in the investment decision-making stage，the project of the techno-economic decision-making，as well as the cost of construction projects completed and put into production after the project cost-effective，have a decisive impact on the construction project cost control is an important stage. Project cost management as a decision-making stage in the feasibility study report shall be prepared，and economic evaluation of the proposed project，select the technically feasible and economically the construction of example programs and to optimize the construction program on the basis of the preparation of high-quality items investment is estimated that the project construction so that the real control of the project has played the role of total investment.
The impact of the decision-making phase of the project cost are the main factors：a，the determine level of construction standards；b，the choice of built-up areas；c，building location (site) selection；d，project the economic scale；e，technology selection f，equipment selection .
Such as the choice of built-up areas，there is a basic principle，that is close to raw materials，fuel and consumer principles. This project completed and put into production，you can avoid the raw materials，fuels，and finished the long-haul transport，reduce costs，lower costs；transportation distance may be shortened to reduce the flow of time，speed up cash flow and is conducive to business. If the project's economic size，economies of scale，product standard is a reasonable means of production volume，a number of products under certain conditions，was "increasing returns" of economic phenomena，that is，with the expansion of production volume，unit cost reduction，revenue increase.
Therefore，in ord
