Research On The Cost Control Of Construction Project Based On Simulate Bill Of Quantities

Since most engineering project construction needs acceleration, the tenderer often bid when the constructions drawings are unfinished, which is also called simulate list biding. On that condition,the using of simulate bill of quantities is popular in Construction which is primary request for time limit for a project. But there will be a lot of problems, such as blackmail by contractor, extension of time, a substantial increase in costs and so on. The simulate bill of quantities is based on design or preliminary design documents, referring to a list of construction projects in the past similar projects and detailed engineering specifications, so it is prepared on the basis of the specific content of uncertainty. Thirdly, compared to bill of quantities,the simulate bill of quantities is uncertainty larger, more prone to omissions, project description and quantity takeoff unclear inaccurate. Based on this, through the“volume and price controls”to reach the goal of cost control of construction projects.Firstly, analyze the range inventory applicable of the simulate bill of quantities to find that it have certain requirements for the project, if the project does not comply, it may produce less effective results. The key point of it is to find the similar projects, and adjust it based on similar characteristics of the simulated inventory. By analyzing the simulate bill of quantities,the biggest weakness is uncertain of quantities. Finally, the recognition and measurement rules of quantities, given the amount of project owners to improve the accuracy of measures to reduce the risk of the project amount allowed.Secondly, analyze the price of the research project which is mainly for the contract price adjustment and quantities deviation causes and risk responsibility. Quantities will be adjusted to the formal completion of the construction drawings for the time node, before the formal completion of the project due to the amount of virtual engineering, the stage of the project should be based on the principles of practical engineering contractor whichever is completed, according to the actual completion of the verification of quantities. After the formal completion of construction drawings, engineering adjustments should adjust for risk-sharing principles. The amount of deviation in the project engineering quantity adjustments is divided into engineering increased under reducing conditions to adjust. When reducing the engineering, integrated unit should be increased, given adjusted by the formula; while in increasing quantities, analysis, given its formula, and giving case studies to illustrate that.Finally, give conclusions and outlook in this article. In the simulate bill of quantities,the key point is looking for similar projects, using tools such as big data, referencing design and standardization of real estate strategies and research methods, establish a database of project cost. Do the contract content, according to the contract price, make the approved list and other content based on fixed unit price between the two sides to take charge content.
