Analysis on Risk Control of Civil Engineering Cost Based on BIM Technology

Abstract

With the rapid development of my country’s construction industry, people’s requirements for construction quality and safety control are becoming more and more stringent. However, the results are often unsatisfactory, and the cost risk in civil engineering construction still cannot be effectively controlled. This article aims to study the risk control analysis of civil engineering costs based on BIM technology. This article analyzes the experiment from the perspective of quantification. The Experimental Integration Facility Engineering Center has conducted research on multiple BIM projects and learned about the actual operation status of these projects. Then summarize the actual effect of BIM technology. Experimental data shows that the use of BIM technology can improve the quality of design, quickly determine project cost, control design changes, avoid rework, and reduce costs. The experimental results show that the use of BIM can reduce the time used to estimate the cost to 35%, the accuracy of the estimate is controlled to <5%; the extra-budgetary changes are reduced to 70%; through the discovery and resolution of conflicts, the contract price is reduced by 13%; The project time has been reduced by 10%, and investment income can be obtained relatively quickly. Therefore, the research on construction hazard management and control based on BIM technology can not only promote the development of BIM information technology, but also make up for the inefficient and imperfect defects of hazard management and control, and greatly improve the cost risk of civil engineering.
