Effectively managing and controlling construction project costs is essential to keep expenses within a reasonable range and enhance the project’s economic benefits. Building Information Modeling (BIM) is an emerging technology that offers a comprehensive information package. Integrating BIM into construction projects can significantly improve construction quality and efficiency, ensuring the anticipated financial outcomes are met.
1. Direct Engineering Cost Management and Control Using BIM
BIM technology enables unified integration of project personnel, materials, and equipment information for direct cost management and control. By constructing BIM models, relevant data such as labor and material costs can be comprehensively integrated and output. Key aspects include:
(1) Labor cost management can be extended to contract levels, manpower deployment, and material allocation. Establishing a personnel information database allows for systematic and information-based management of workforce details.
(2) Material cost management benefits from BIM by compiling detailed control plans into an information database. This includes procurement processes, material standards, and pricing. Utilizing BIM technology streamlines the management of material information, increasing efficiency and accuracy.
2. Managing Project Change Costs with BIM
In many construction projects, design disciplines operate independently, often leading to inconsistencies and conflicts between design drawings. Each drawing correlates to a cost budget, so any conflicts require adjustments that impact project costs. BIM models allow project managers to quickly detect design errors and conflicts, minimizing the frequency and impact of cost changes.
3. Engineering Measurement Cost Management Based on BIM
Reducing project costs also involves minimizing safety construction expenses. Using BIM technology, project managers can simulate the entire construction process. This simulation helps construction teams identify potential issues before actual work begins, preventing risks and reducing the likelihood of safety accidents during construction.
4. Dynamic Cost Monitoring Mechanism Using BIM
Throughout construction, BIM technology supports dynamic monitoring of progress, enabling cost accounting aligned with real-time project status. The accurate data reflected in BIM models helps reduce errors in cost estimation and enhances the precision of budget forecasts, supporting better financial control.
