The Empirical Research Of Unbalanced Quotation Of Gansu Agricultural University Experimental Teaching Center

Under the severe challenges of the ongoing economic downward pressure, China’s construction industry output a new low value in the 24 years, some construction enterprises present a precipice type falling profits. the construction industry’s profits have tend to be small profit, listing price as well as the practice of electronic bidding evaluation method, Make bidding open, fair and just got bigger, but competition among contractors will be more intense. in order to win market share, the contractor must constantly improve their ability to fight the market, begin to establishing profit targets system from the tender period,in order to maximize profits, the contractor must research constantly.The profits strategies of the unbalanced method under the mode of listing offer is most commonly used, because in bidding for a project, it is not easy to find the method, the gains is very obvious in settlement stage, and can use variety of method to operation, the general contractor in the quotation, will use this strategy, but this method has a very optional. So it best to form a theory method, and master the use of unbalanced quotation skill, to maximize the interests of the project. The contractor in the tender process pay more and more attention to the effective use of unbalanced quotation, however blindly use the result of the unbalanced quotation without additional income, not only cause the enterprise to interests losses, or cause the contract unable to fulfill.Based on this, the paper to unbalanced bidding strategies as the research target. and further expounds the reasons of emerge, and the significance of research, summarizes the matters needing attention during using this method. Through the establishment of the model of the demonstration analysis. The main results obtained are as follows:(1) by combination of time unbalanced quotation and quantity unbalanced quotation, forecast the future change of quantities, calculate construction schedule, with the help of four kinds of scheme comparison method, determined the comprehensive unit price adjustment direction of the project;(2) established the unbalanced quotation integrated model.Choose fuzzy comprehensive evaluation method to determine the adjustment range of unit price, and use the unit price adjustment range to make overall evaluation, identify the factors that influence the unit price adjustment range, integrate considering the quantity unbalanced quotation and the time unbalanced quotation, the optimal combination of the comprehensive unit price have been got. Using the method of time value of money, discount the unbalanced quotation proceeds, and verify the validity of the model.(3) take the Gansu agricultural university experimental teaching center I section of A building contractor offer as an example to empirical analysis:Accordance with the requirements of the tender documents, combined with the construction organization design and construction scheme, determine the construction schedule. Has a comprehensive analysis and research to the Bill of quantities provided by the owner, according to the drawings, construction specifications, prediction calculation of quantities, reasonably determine the comprehensive unit price adjustment direction; Determine the comprehensive unit price adjustment range, calculate the optimal combination of the comprehensive unit price; considering the bidding total quotation In the optimal price and owner’s control price;using the time value of money comprehensive model, calculation and analysis the achieve profit through the unbalanced quotation, through the calculation and analysis three comprehensive income tables by using the comprehensive model of unbalanced quotation, verify the validity of the model, for the future similar projects in the actual application of unbalanced quotation method provides a practical calculation analysis and evaluation method.
