Study On Engineering Claims Management Based On The Mode Of Valuation With Bill Of Quantities

Claim is a kind of normal economic phenomenon in Construction project.Engineering contract both sides will inevitably produce all sorts of problems withconstruction difficulty rise ceaselessly, engineering technology unceasing complication,engineering scale expanding. Especially in the new mode of valuation with bill ofquantities, the engineering contract relations changed, also can appear new claim event."The winning by low price, profit by claim" is the experience of a lot of contractor.They often through the low price strategy to win the bid, claim safeguard their interestsin the engineering process and make a profit. This will bring a sense of urgency to theowner whose engineering claims management level is relatively backward. So, theowner should carry out a effective management of the engineering claim in theengineering construction management process.The paper make a research of the engineering claim management from theperspective of the owner, puts forward a view that use the bayesian theory applied toclaim management decision. First of all, the paper discusses the overseas and domesticresearch status of engineering claims and the quantities bill valuation mode. It comes tothe conclusion that the quantitative study depth of engineering claims, under thequantities bill valuation mode, should be improved. And then it put forward the purpose,significance, content and method of its research. Afterwards, the paper minutelyinterprets the concepts and features of game theory, Bayesian theory, the engineeringclaim and the quantities bill valuation mode. It also introduces the concrete program ofBayesian theory applied to the engineering claim decision. This is the unique point ofthe paper. With that, it introduces the owner’s method and decision of engineering claimmanagement under the quantities bill valuation mode, in order to maintain the legalrights of the owner and solve the engineering claims event better and faster. Finally, thepaper conducts quantitative research of engineering claim management. It establishesthe model of the owner’s engineering claim management, which solved by Bayesiantheory, and analyses with a project case in order to describe vividly its applicationprogram. The writer hopes the paper could has certain instructive and realisticsignificance for the engineering claim practice, and offers help for owner proceedingproject management.
