Integration between different construction bidding models to improve profitability and reduce prices

Abstract Unbalanced construction bidding covers different allocations of mark-up between contract project items to attempt and increase win chances with unbalance but without changing of total bid price. Many models have been developed to increase both the systemized execution and detection of unbalancing but, although unbalancing is thought to be widespread in general, substantially not known it use. Proposed unbalanced construction bidding models of many researchers neglected part of improve profitability. This paper inspects and integrates the construction bidding models techniques for determining price of each unit quantity and take advantage of bidder benefits, then all proposed mathematical models is studied carefully and more modifications will be done to tries to be fair and equitable for providing owner quantities that impact directly on items prices. Finally it was concluded that the maximum/minimum models are preferred for many world cases. At end of paper, a case of study will be presented to demonstrate the use of proposed models for optimizing project bidding. Also, this paper will serve as a guide for construction project stakeholders with effective management to perform a competitive level of project pricing.
