Bidding Risk Management Theory And Method Based On The Bill Of Quantities

Along with the social productivity progress, the market competition is becoming more hotly contested, and the split market and market competition also become increasingly international after China accessing to the World Trade Organization (WTO). In order to integrate into the international market, China has introduced FIDIC provision. Meanwhile, Bill of Quantities valuation approach was used in the bidding process of construction companies, this action brings a lot of risks in the bidding process. In order to reduce the loss of ricks, construction companies need careful study, especially the risk management activities in the bidding process.Firstly, in allusion to the risk management in bidding process, project risk, theoretical knowledge of bidding and project risk management under bill of quantities mode are described. And the bidding risk management research approaches were summarized through the collection of relevant domestic and foreign research data.Then, China has introduced Bill of Quantities mode in the bidding activities in order to align with the international community. Based on the risk problems in Technical Bid and Commercial Bid, this paper divided bidding process into three stages. They are bidding preparation phase, implementation phase, and awarding tender phase. Risks in Technical Bid and Commercial Bid were recognized from these three stages respectively, and the risks in the bidding process were be targeted worked out. These research results provide a feasible and effective way to control and reduce the loss in the bidding process to the tender.Thirdly, bid quote risk was more significantly impact than other different kinds of risks in building construction bidding activities. The risk of bid quote includes the risk of the colluding behavior in bidding and unbalanced quotes. Due to the colluding risk in bidding, this paper established a game matrix. This mode discussed whether the bidder is involved in the accompanying-bidding and whether the tenderee has the inspection. This model also effectively solved the colluding bidding and other illegal problems in bidding process. At the same time, this paper established a system which based on Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation method to identify imbalances quote. It can solve the risk problems of unbalanced quotation under current bill of valuation model.1) This article combined AHP and fuzzy comprehensive evaluation, and analyzed the relevance of similar projects and bidding projects, obtained the adjoin degree data of similar projects; 2) During the process of analyzing the correlation index, considering the limitations of the ability and experience of different experts, Set-Valued Statistics was used in this paper which make the experts’evaluation more objective.3) Establishing the bid evaluation guidance price which can avoid unreasonable price, while a standard price of integrated unit price in subentry engineering offers a reference in commercial bid appraisement.4) This paper uses the mathematical expectation and standard deviation to identify imbalances quote. The degree of dispersion of the quotes is analyzed and also the imbalance is sorted. This provides a new method of imbalance quote in bid evaluation.
