Digital Application of Construction Project Cost Risk Control and Management Based on BIM Technology

Abstract

The core objective of this study is to explore the application of BIM technology in the whole process of cost management of construction projects and to assess the project risk. The study covers the key stages of project planning, design, transaction and construction, and focuses on analyzing the cost management process of investment decision, design estimate, transaction and construction. Through questionnaire surveys and expert interviews with 72 valid samples, this study collects data on green building and analyzes the quality of the risk assessment data. Through questionnaire survey and expert interviews with 72 good samples, this study collects data on green building and analyzes the quality of the risk assessment data. In establishing the BIM-based project cost risk model, the study analyzes the management elements of BIM and IPD in detail, including the quantification of technical and management components. three case projects show that the application of BIM and IPD technologies in different projects has different focuses, and produces other management effects. for example, the number of engineering changes (e.g., the number of changes to the project) exhibited by the project B For example, the number of project changes (NCO) is 35, the cost change rate (COP) is 0.93%, the duration change rate (DCP) is −10.25%, and the number of contract negotiations (NRFI) is 6. The risk evaluation model is applied in a mixed-use project in Xiamen, China, and the results of the simulation experiments show that the method is effective in realizing the risk assessment of the construction project, and the clustered nature of the output features is good. The average value of the risk fuzzy variable is 0.576, and the minimum value is 0.192.

Comparative Analysis of Conventional Methods with BIM Methods on Construction Cost Estimate at Structure Project Design Calculations (Case Study of Construction of A Satpol PP Building)

“…One of the impacts is that it allows infrastructure development to be faster and be more efficient. Building Information Modeling (BIM) is a method, system, or management of a work that is planned and projected in 3-dimensional modeling and contains information on planning, design, implementation, control, and maintenance that can be integrated with stakeholders (owners, consultants, contractors) (Li, 2024;Ojeda, 2024). Autodesk Revit is one of the software that has adopted the BIM system.…”
