Study on Unbalanced Bidding of Contractor Based on Engineering Change

Contractor uses the unbalanced bidding strategies for the income-generating, because unbalanced bidding can link the engineering change and income-generating. However the lack of knowledge for the change of project state is the key factor that the contractor can not achieve income-generating successfully. First the thesis identified the opportunity of contractor's unbalanced bidding from the construction plan, design drawings, and project amount. By introducing the trigger mechanism to show the trigger mechanism of the unbalanced bidding, it indicates that only when the unbalanced bidding is triggered by the engineering Change the state of project will execute as expected and the profit of contractor can ultimately change from A''' to B'''. Through analyzing the change of state of project under engineering change, the thesis gives unbalanced bidding strategy for contractor.
