Study On The Bid Appraising Approach Priced With Bill Of Quantities Based On Value Engineering

The bid system is a kind of international and effectual pattern to select contractor. The experience of tender applying BOQ mode oversea indicates that it is an effectual method to disposition resources and it adapts to the market economy. It has a very big improvement and development in our country on the base of BOQ mode in evaluating the project price and tender because of starting late. Tender evaluation is the premise stage of engineering project implementation, and it is the key factor whether a bid work is successful or not. However, the domestic evaluation of tenders work at present is often carried on by the tender committee, who is organized by the owner or the consultant firm. In this process, the fairness of tender evaluation is suspected because of the big subjectivity, the many pacing factors and few of quantitative analysis.Two kinds of approach are most used in domestic project construction bid apprising: comprehensive evaluating and reasonable-low price evaluation. But the approach can't actually evaluate bidder's management level and technical level. So the successful bidder is not always the best tender. In view of the existing assessment method flaw, this thesis introduces value engineering theory to project construction bid evaluating. VE provides a new thinking of quantitative and analytical way.This thesis first analyzes the domestic and foreign price pattern of BOQ mode and present bid evaluating research situation under the mode firstly, and points out the existed problems and uncertainty existing in project BOQ appraise. Then elaborate traditional bid evaluating and theoretical basis of VE. The target system of pre-censor about corporation's qualification and bid evaluating index is founded, and with AHP definite target weight. VE evaluation of project construction tenders model is established. An example about some unit 1 apartment building construction tender project is carried on the VE evaluation.VE model doesn't abandon from CE. But it is beneficial supplement and revision. VE model seeks the best balance point about function and cost, and obtains the best combined earnings. The result of the case and the actual evaluation of tenders result tally basically. This indicated the entire evaluation of tender model in the target selection and the data processing is feasible. And the model computed result is reasonable.
