| Traditional quota pricing always cannot reflect present market price, making the budget of the proposed construction project deviant from it's actual value, and then leading to project cost abuse. Bill of quantities (BOQ) pricing model have made up for the defects, and gradually replaced quota pricing. In practice, however, still exists cost control risk during application of BOQ pricing model. So it's urgent to study the problems existing in actual project cost management under BOQ pricing model, and analysis it's cost management measures.The thesis combined practical experience of the project B, and analyzed cost control problems existing in investment stage, implementation stage and final accounts stage respectively, such as the valuation way behind, investment estimation errors, irregularities, design items, engineering change, quota set artificially high and inflated quantities, etc. The rectify means used in this project are also introduced. Then analyzed cost management measures adopted in different project phase of project B respectively, including incentive mechanism, engineering change and claim for compensation as well as investment contract management, etc. Finally, according to cost management of garage platform of project B, actual project application of BOQ pricing model is studied. Problems existing in cost management during investment stage and bidding stage are analyzed respectively. Measures of cost control taken in implementation are analyzed respectively. The effect of cost management measures is proven through a comparison between before and after its implementation. the cost management experience of project B is summarized.The thesis studied problems existing in BOQ pricing model in actual cost management, summed up the cost management measures based on BOQ pricing, and tested existing pricing theory with implementation. This thesis would be of reference significance to actual construction project cost management using BOQ pricing model. |
