| Project general contracting mode fundamentally solves the problem of incoordination between design and construction under the traditional contract mode and gradually becomes the dominant mode of international project transactions.In this mode,the contractor’s intervention time is advanced,and how to bid for tender becomes an important choice for the owner in the actual operation.In order to start construction as soon as possible,some owners adopt the way of rate bidding,but in this way,the project cost is fuzzy,the owners can not control the cost "in advance",the group price disputes are many,the settlement cycle is long and other problems are obvious.As a compromise between rate bidding and bill of quantities bidding,the simulated bill of quantities can not only shorten the construction period,but also effectively solve the problem of fuzziness in cost,which is favored by the owners.However,the characteristics of "simulation" cannot be avoided in the simulated bill of quantities.Problems such as missing items,large deviation of quantities and unbalanced quotation of contractors often occur in the application process,leading to the owner’s investment out of control.In fact,the hidden risks brought by the simulated bill of quantities are mostly the "bad results" buried in the bidding stage.Therefore,for the general contracting projects that adopt the simulated bill of quantities bidding,the control in the bidding stage is very important.Therefore,this paper will mainly study the three key technologies in the bidding stage.The specific research contents are as follows:The first is the preparation of the simulated bill of quantities.To improve the accuracy of the simulated bill of quantities,this paper studies the preparation of the simulated bill of quantities.Through literature research,the process of compiling the simulated bill of quantities is combed out,and three key technologies are identified,including searching for standard items,adjusting and reviewing the bill of quantities,and forming the standard bill of quantities,which can improve the quality of compiling the simulated bill of quantities to a certain extent.The second is the study of the general contract under the simulated list bidding.This paper studies the problem of contract setting in order to stabilize the owner’s investment.First by analyzing the environment and the implement of engineering general contracting project contracts the difference at home and abroad,it is concluded that China formed to promote engineering general contracting project general contracting mode with Chinese characteristics,namely the integration of form,reality of the bat,use of the terms of the contract and stable investment,thus put forward simulation under the bill of quantities bidding contract control of three main points,including the finite fixed price contract,according to the principle of "consistency" adjust listing,rationally divided the risk liability of both parties.The last part is the study of contractor selection under simulated list bidding.This paper optimizes the process of prequalification and bid evaluation with the aim of selecting the best contractors.Due to the information asymmetry between the two sides of the transaction,the adverse selection of the contractor is mainly derived from the pre-qualification and bid evaluation links.Therefore,this paper proposes optimization suggestions for the above two links in combination with the characteristics of the simulated bill of quantities bidding.In conclusion,this paper combined with significant cost theory and the theory of information asymmetry,and text analysis,literature review method and other methods,from the simulation of the bill of quantities,set of general contract and the contractor selection three aspects,for the simulation of the bill of quantities bidding engineering general contracting project carried out smoothly. |
