BIM technology has evolved significantly, expanding its application from the initial design stage to include the bidding, construction, and operation management phases. Initially, BIM was primarily used during the design phase, focusing on architectural design to represent irregular building shapes. Over time, its use extended to structural design, with leading design firms in China experimenting with 3D design to produce construction drawings. Currently, with increasing national emphasis on green construction, the application of BIM during bidding and construction stages has deepened, allowing BIM to play a vital role throughout the construction process.
The shift of BIM from solely a design tool to a comprehensive technology used during construction demonstrates its growing implementation. Fully leveraging BIM’s potential in engineering construction is essential to address the widespread challenges of project management. This enables refined construction management, facilitates project execution, and supports environmentally-friendly and technologically advanced building practices.
The Value of BIM Applications Across Engineering Stages
Bidding Phase Applications:
1. Business standards: Employing BIM for accurate cost forecasting and budget control.
2. Technical standards: Using BIM to visualize project construction details and simulate the construction process, thereby improving technical assessment scores.
Significance: BIM can be a crucial advantage during bidding, with many tenders explicitly requiring the use of BIM technology.
Design Phase Applications:
1. Transition from traditional 2D design to single-discipline 3D design, enabling the export of three-dimensional construction drawings.
2. Facilitating multidisciplinary collaborative design to proactively identify and address potential conflicts.
Significance: BIM technology drives a transformative shift in the design industry.
Construction Phase Applications:
1. Preparation stage: Using BIM to simulate site layouts, develop specialized construction plans, identify high-rise formwork areas, and review drawings.
2. Construction stage: Employing BIM models for pre-construction briefings, 3D-guided construction documentation, visualization of complex construction nodes, 4D progress tracking, material requisition, and exporting engineering quantity data.
Significance: These are the critical phases for BIM implementation, though its full value in preparation and construction is still being explored.
Operation and Maintenance Phase Applications:
1. Storing engineering design and construction information to ensure continuity through BIM models.
2. Enabling real-time, three-dimensional maintenance management.
