Engineering Cost Control Study Of Construction Union List Valuation Model At Bidding And Construction Stage

Because of the serious “three outspend” phenomenon of construction engineering in our country, the project investment was out of control, which affects the social and economic benefits of the project. Quantity pricing model could reflect the individual cost of the enterprise, and also could be advantageous to the construction unit to choose the high quality construction unit, so as to control the construction cost reasonably. However,as the subject of construction engineering, construction units of the project cost control status was mainly ignored prebidding stage of cost control and excessive dependence to the client management consultants and the list of code of valuation had been revising constantly. So in this case, how to control the cost of the construction unit reasonably and reduce the “three outspend” phenomenon was worth in-depth study of the problem.Therefore, this paper took the construction unit as the angle of view and carried on the analysis to the current list valuation standard, and on the basis of theoretical study, discussed engineering cost control measures of the two stages of bidding and construction under the quantity pricing model. So the construction unit can control the project cost reasonably in the project budget.First, this paper analyzed the shortcomings of the current list price of norms that exist in the use and cost of the construction unit in the bidding phase control impact; Proposed that construction unit must be combined with the existing pricing norms drawn from the main terms of the contract, preparation of tender documents, evaluation and other aspects, early prevention and control for the construction unit to achieve a reasonable cost control purposes to provide protection. During the construction phase, build model and solve model by the expert consultation method to get the factors(including engineering change, site visa, engineering claims, the price of materials and equipment) which increased cost, and put forward the control measures of cost during constrution So that the construction unit could control cost in an active state control on this stage.Finally, combined with the bidding phase prior cost control and cost control in the construction phase of matter through the actual project application,construction unit could achieve a good cost control effect. The cost controlmeasures in this paper can provide some reference for the actual construction unit cost control.
