As large-scale public buildings continue to rise across our country, traditional construction management methods have become clearly outdated. This has led to management challenges and confusion, causing construction delays and significant cost overruns. The emergence of BIM (Building Information Modeling) technology offers an effective solution to these issues. Let’s explore how BIM technology is applied in the construction management of large public buildings.
1. Visual Construction Document Storage
BIM technology enables all project stakeholders to collaborate seamlessly through networked platforms, facilitating engineering negotiations, coordination, and comprehensive management of construction quality, safety, costs, and schedules. Traditionally, construction documents have been stored as paper records or 2D electronic archives, which often become inaccessible and lose practical value after project completion.
Cost document management based on BIM models involves manually linking documents to corresponding parts of the BIM model. This system integrates powerful search, review, and location functions for documents, all operating through 4D technology. Using BIM visualization within the model interface significantly enhances the intuitiveness of data retrieval and improves the utilization of cost-related information. Once construction is complete, a comprehensive information database is automatically created, providing quick access and precise location identification for project cost management personnel.
2. Basic Data Sharing and Retrieval
BIM contains extensive engineering-related information, providing robust support for the project’s data backend. It allows owners, design institutes, consulting firms, general contractors, subcontractors, material suppliers, and other stakeholders to share data on a unified platform. This shared environment streamlines communication, strengthens collaboration, and improves overall project management efficiency.
BIM dynamically adjusts construction quantities based on design optimizations and changes, storing all relevant data from project initiation through completion on a backend server. This comprehensive data repository enables management personnel to parameterize and retrieve essential engineering data both during construction and post-completion accurately and in real time.
The success or failure of management and coordination throughout the construction process critically impacts project quality and progress. Fully leveraging the BIM sharing platform enables true information exchange and efficient management. Additionally, BIM-exported data substantially reduces the workload of onsite surveying and mapping. This shifts the traditional scattered construction approach to an integrated and modular onsite process, effectively addressing challenges such as limited onsite space, vertical transportation difficulties, and quality control issues.
3. Refined Project Management and Cost Control
BIM-based project management offers precise, transparent, and shared engineering data—such as quantities and prices—that enable tight financial risk control and profit target achievement throughout the project lifecycle, even within short timeframes. Cost calculations and overall financial management within BIM are conducted through dynamic comparisons between BIM data and actual project expenses.
Engineering cost software built on BIM technology unifies the management of bidding documents, progress review budgets, and settlement documents, facilitating data comparison. It also manages construction attachments like contracts, payment vouchers, and change orders, covering the entire cost process from estimation and bidding to visa management and payments.
Visual tools such as pie charts and tree diagrams allow stakeholders to intuitively understand the status of each engineering project, enabling better control over the entire cost management process. The BIM data model supports dynamic data adjustments for each project, making cash flow tracking and financial analysis straightforward. By summarizing project progress, BIM empowers leadership to allocate resources more effectively and make informed decisions.
Through this overview, we hope you have gained a clearer understanding of how BIM technology is transforming construction management in large public buildings. With the widespread and deepening adoption of BIM technology in China, we anticipate uncovering even more valuable applications in the future.
