Establishing project management informatization through BIM applications can significantly enhance production efficiency, improve building quality, shorten construction timelines, and reduce overall costs. This is specifically reflected in several key areas:
3D Rendering and Promotional Display
3D rendering animations provide a realistic and visually impactful experience. The BIM model serves as a foundation for secondary rendering development, greatly improving the accuracy and efficiency of 3D visualizations. This enables clearer presentations to owners, increasing the chances of winning bids.
Faster Calculations with Improved Accuracy
By creating a BIM database and establishing a 6D linked database, project quantities can be calculated accurately and quickly. This enhances the precision and efficiency of construction budgeting. Due to the detailed component-level data in the BIM database, essential information is readily available to support management across various project sectors, significantly improving construction management efficiency. BIM technology also automates physical quantity calculations—a traditional function of quantity calculation software widely applied in China.
Accurate Planning to Minimize Waste
One of the main challenges in achieving refined management in construction is handling vast amounts of engineering data, which often cannot be obtained quickly or accurately. This leads to reliance on empirical methods. BIM enables management teams to access precise engineering data promptly, supporting better resource planning. This results in more accurate workforce planning, reduces waste in resources, logistics, and storage, and provides technical support for controlling material requisitions and consumption.
Comparative Analysis for Effective Control
Data is the backbone of management, and managing engineering data is fundamental to project management. BIM databases allow real-time access to basic engineering information. By comparing data such as consumption, unit prices, and total costs from contracts, plans, and actual construction, project managers can assess profitability, detect cost overruns, and monitor purchasing and subcontracting prices. This facilitates effective control over project cost risks.
Virtual Construction for Enhanced Collaboration
Combining 3D visualization with scheduling enables virtual construction. This allows stakeholders to intuitively and quickly compare planned progress with actual progress anytime and anywhere, fostering effective collaboration. Construction teams, supervisors, and even non-technical leaders can better understand project issues. Integrating BIM technology with construction plans, simulations, and on-site video monitoring significantly reduces quality and safety problems, as well as rework and corrections.
Collision Detection to Reduce Rework
BIM’s most intuitive feature is its 3D visualization capability. Early-stage collision detection using BIM technology helps optimize engineering designs, reducing errors, losses, and rework during construction. It also improves clearance and pipeline layout schemes. Construction teams can use the collision-optimized 3D pipeline plans for construction coordination and simulation, enhancing build quality and communication with owners.
Conflict Resolution and Decision Support
BIM data is computable and integrates large amounts of engineering information, providing strong support for project data management. Basic project data in BIM can be coordinated and shared across management departments. Engineering quantity information can be summarized, segmented, and analyzed by spatial and temporal dimensions, as well as by component types. This ensures timely and accurate data delivery, supporting decision-makers in project group management, progress payments, and cost control.
