Application Of BIM In Construction Project Cost Control

Since the reform and opening up decades,China's construction industry unprecedented development,high-quality and low-cost development goals have become the focus of investors's attention.However,it is very difficult to effectively control costs,and it is influenced by many internal factors and external factors in the whole process from design to application.The change is also very large,and it is often one of the reasons for the disputebetween the owner and the construction party.Building Information Model(Building Information Model)accommodates a project from the early investment,design,construction,operation and maintenance,removal phase of the full life of the data generated,it achieved the project's data transmission and the accuracy,So that managers and participants actively cooperate to achieve full-cycle dynamic management of the project,making cost control to get the actual results.Based on the above background,in order to expound the application research of BIM in cost control of project investment,design,construction to operation and maintenance stage,improve efficiency and reduce project cost,this paper mainly completes the following work:1.Explain the concept and characteristics of BIM and discuss the innovations and advantages of BIM technology to the management model and cost control methods of the project participants(owners,designers and builders).Discuss the characteristics and advantages of the IFC standard and the related software situation of BIM.2.Analyze the status quo of the construction industry,leading to the importance of cost control.In this paper,BIM technology and cost method in the Earned Value and cost analysis method to discuss the project in the early investment,design,construction and cost management methods,cost control of the content,measures and cost management methods are described.BIM technology in the operation and maintenance phase in the manual,materials and machinery and other cost of effective control.3.Discuss the various stages of the specific application of BIM technology for project cost control methods.This paper discusses the technical application of BIM in the whole life cycle of the construction project.The project is modeled and estimated by Revit in the early stage of investment decision-making.Energy analysis is carried out in combination with Ecotect software.The design stage can use Revit to directly derive the engineering quantity,Import Navisworks software for collision check,reduce design changes;construction process using Navisworks software for construction simulation,and with the Project construction progress management.4.Finally,through the actual case to test the above work in each project stage of the benefits of the project,the above work have been successful in improving the work efficiency,ahead of schedule than the planned work to reduce the cost of the project,cost control is greatly beneficial.So BIM technology and engineering investment,design,construction and operation and maintenance period of cost control work together to effectively improve the current cost control work to improve the efficiency of cost management and accuracy.
