Today, we will discuss the practical applications of BIM in construction and its advantages. Once the project enters the construction phase, the BIM model verification process involves the construction vendor continuously developing and refining the BIM model according to contract requirements. This includes integrating project interfaces, identifying and resolving conflicts, showcasing interior decoration materials, providing 3D visualizations, and supporting various construction management tasks. Regular review meetings are held, and stage progress reports are submitted. If any issues arise, feedback is provided to the design team for clarification to ensure smooth construction progress.
1. Conflict Review and Clash Detection
Structural Engineering
It is essential to establish detailed engineering information for structural components, such as dimensions and material types, and to examine reinforcement clashes at component joints. Performing clash analysis and resolving conflicts in advance helps reduce on-site errors. For example, in complex scenarios like steel-reinforced beam-column joints, BIM can provide early warnings. On-site engineers then coordinate the construction process and workspace between the steel structure and reinforcement teams. The structural phase also emphasizes verifying the accuracy and constructability of floor slab height differences and opening positions.
The construction contractor is responsible for reviewing downgrading positions and the relationships between multiple sections, identifying issues, and proposing solutions for all parties to discuss and finalize. Following feedback, the BIM model is updated accordingly.
Mechanical and Electrical Engineering
Mechanical and electrical systems are coordinated alongside the structural construction schedule, integrating systems such as water supply, drainage, electrical, fire protection, and HVAC. BIM models are developed and reviewed floor by floor, detailing equipment, pipe fittings, and structural connections. Information such as size, length, and quantity is provided, and pipeline connectivity is verified.
In the past, reviews relied on 2D mechanical and electrical integration diagrams (CSD) and structural mechanical and electrical diagrams (SEM). However, with the adoption of BIM, 3D visualization allows easy detection of elevation conflicts and clashes between equipment, pipelines, and structures, significantly improving interface management efficiency and accuracy.
Analysis of Issue Types
In recent years, the construction market has expanded and project timelines have tightened. The compressed planning and design schedules increase the difficulty of horizontal integration, making detailed BIM model reviews crucial for identifying incomplete areas. The issues identified during project inspections include drawing discrepancies, clashes, construction challenges, functional deficiencies, interface conflicts, and structural concerns.
By proactively proposing conflict resolution strategies, coordinating feedback from multiple stakeholders, and balancing design intent with construction feasibility, BIM fosters smoother project execution.
2. Enhancing Construction Safety Management
Construction Route and Process Simulation
For instance, before steel structure lifting operations commence, BIM is used to simulate the construction schedule, including crane positioning, boom reach, and structural stability checks at each stage. This allows for advanced assessment of safety and coordination between lifting operations and other ongoing work.
Construction Scaffold Planning
BIM models are developed for construction scaffolding to simulate assembly methods and regulatory compliance ahead of time. Considering risks such as self-weight and wind loads, the contractor proposed a three-stage assembly approach. The interface between scaffolding and the main structure was carefully checked, scaffold positioning was adjusted in coordination with adjacent structural walls, and horizontal platforms and cross ties were added for enhanced stability.
3. Comparing Construction Execution with Inspection Results
One of BIM’s advanced applications is integrating a time dimension by combining 3D models with construction scheduling. This allows for process adjustments and progress tracking throughout the project.
By simulating the construction schedule in BIM, supervisors and project owners can visually track the current status and compare it against planned timelines, improving oversight and management.
