The Research About Cost Management At Construction Stage Based On BIM

Along with the standardized development of China's construction market pricing model,fierce market competition makes bidding offers for construction companies very transparent,the profit space is decreasing,and the quality and wage war between construction enterprises has become a price war.Construction enterprises continuously lower bid price quotations in the bidding process,a serious problem has been facing the construction enterprise,that is how to strengthen the management of their own costs,reduce the waste of resources,reduce the project cost,ensure the winning project can keep a little profit space,achieve the goal of the construction enterprise is to survive and develop first.However,at present,the construction enterprises in the project cost management exist a lot of problems such as the management of extensive information,the lack of information,the weak technical force,the field management and cost management out of sync and so on,construction enterprise management efficiency becomes low,the resources are wasted seriously,the rework of the project rework is not uncommon,the construction cost is high.How to solve the above problems of Construction enterprises cost management,reduce resource waste,ensure that each department information unobstructed,achieve synchronization field management and cost management,enhance the level of cost management and reduce the construction cost is imminent.In the current market situation,the application of building information model,To promote the informatization of cost management of construction enterprises to a certain extent can solve the above problem,at the same time can play a positive role in reducing construction cost.The paper will focus on the research and analysis of the project cost forecast,cost planning,cost control and cost assessment of the construction stage,to solve the construction enterprises in the construction phase of the project cost management problems,such as the existence of extensive management,resource waste cost is high,the information not unobstructed,project schedule management and cost management are not synchronized,The main cause of these problems include the limitations of the company management system,information level is low,cost planning is not scientific,the cost information,imperfect supervision system,the communication goal responsibility is not clear,rewards and punishment system is difficult to implement,etc.Combining BIM advantage with project cost management,to propose the solution of project cost management problem based on BIM technology in the construction stage of construction enterprises,To study and analyze the application of BIM technology combines with cost management in every process can play a positive role in improving the cost management level,lowering the construction cost,providing information sharing platform to strengthen communication,clarifying the target of responsibility,and implementing the system of rewards and punishment.Take the T construction enterprise X project as an example,BIM is valuable in construction stage project cost management and The application and promotion of BIM can positively influence the cost management of construction enterprises in China.
