1、costs manages on entire process First, The necessary of control construction costs manages on entire processTalk 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 sy
2、stem 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 me
3、ter 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-fi
4、nal 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 secret
5、ly 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 d
6、o 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
7、 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 c
8、onstruction 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 ra
9、tional 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 de
10、cision 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
11、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 a
12、ccording 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 materi
13、al prices not working out according to market quotations.(3) construction units bring forward the too high for exceeding a design criterion2、The design stage of construction costs is not under the control of strictThe design stage is the faucet in that project construction costs controls. After the
14、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
15、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 t
16、he 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
17、 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 constructions establishment. Mass and depth that engineering design pursues etc. is also insufficient , amounts project mistakes in amo
18、unts project detailed lists calculates , misses and not calculating, cant 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
19、detailed list quoted price way being applied or used universally on the international all roundAdopt the amounts project detailed list quoted price way being put into use commonly on the international , is that our country construction costs system reforms and cause the inevitable trend reforming to
20、 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,
21、 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 bidders lawful rights and interests also effectively. With the sociali
22、st 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.
23、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 regulat
24、ion , 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
25、 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
26、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
27、project settlement; Receive a track step by step with the convention controlling amounts , guiding price , competing for a fees on the international, deepen the reformation that project valuation manages mainly according to the marketplace changes development, taking ones place on the international
28、market for our country contracts business creates condition.4、The stage being under construction controls lack to construction costsWant to have strict control design alteration too in the stage being under construction. Guard the pass though that working drawing appears in joint trial or are able t
29、o 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
30、 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 stages controls a project inefficientlyThat the fi
31、nal 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
32、 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 personnels signature and being related to if the design alteration advice note must be made known to low
