A Study On Bill Valuation-based Construction Contract Management

This thesis summarizes the difference between fixed quota valuation and bill of quantity (BOQ) valuation, and studies the 2013 new norms of BOQ valuation and the corresponding sample construction contract. The study finds the advantages and disadvantages of BOQ valuation, as well as the characteristics, strengths and significance of 2013 BOQ valuation.A distinction is made between the construction contract and the constructing contract, while elaboration is given to features, risks and goals of constructing contract management, which paves the way for the following design of performance evaluation model for constructing contract management.As an essential part of the constructing contract, priced BOQ is the key to the overall project investment control. Therefore, the unbalanced quoted price in bidding is introduced. After explaining the difference between the unbalanced bid and optimal unbalanced bid, the thesis adopts mathematical modelling and frequency analysis to examine the unbalanced bid in the bidding process. The optimal adjustment range is thus found.Differing from previous construction enterprise-based studies, this thesis takes the perspective of the construction unit to address the issue of performance evaluation of constructing contract management. Through setting dimensions, criteria and standards, a sound evaluation system is built, which can both monitor the process and render qualitative final evaluation.
