As the saying goes, without rules, there can be no harmony. The same principle applies to engineering, especially when it comes to BIM Technology. After winning a project bid, the construction contractor must submit a BIM plan for the construction phase—covering building, water and electricity, and air conditioning engineering—that outlines how BIM technology will be utilized.
So, what should the BIM plan from the construction party include when executing engineering-related projects using BIM technology?
1. Review of drawing methods.
2. Methods for archive output.
3. Explanation of BIM applications in construction management.
4. A complete execution framework, including personnel organization, scheduling of milestones, task management methods, and operational procedures.
5. A comprehensive collaborative management platform detailing the processes for model construction, analysis, coordination, integration, and progress tracking tools.
6. An overall strategy to meet the client’s (Party A’s) requirements for building information modeling standards.
7. Engineering feasibility analysis conducted through BIM.
8. Visual representations—including images and auxiliary animations—of key building equipment (such as mechanical and electrical systems, air conditioning units, cooling towers), along with the space needed for their operation, maintenance, and upgrades.
9. Compatibility considerations, including file formats, model building, data transfer, and software access for collaborative vendors.
10. Strategies for collaborative work with relevant vendors, such as collision detection and construction progress control. The BIM model’s level of detail should support conflict detection, construction drawing production, 4D construction simulation, and help all parties identify issues throughout the construction phase. After discussion and confirmation, feedback must be provided to correct the BIM model.
11. The construction contractor is responsible for compiling and verifying the final BIM completion model. Upon acceptance, they must submit an accurate completion BIM model, BIM application data, and equipment-related information to Party A.
12. The general contractor shall provide a schedule aligned with construction progress during the service period. Using 4D construction planning and engineering scheduling technology, regular updates and integrations of BIM models should be performed based on progress. This includes conducting interface conflict detection and model sand table simulations before starting construction activities.
13. Set up BIM-related software for the construction contractor and manufacturers to build models for owner review. BIM models should be created using tools such as AUTODESK REVIT Architecture, STRUCTURE, MEP, Graphisoft Archicad series, Bentley Microstation series, or other manufacturing modeling software.
14. Confirm that all project information is incorporated into the model construction and integrated through collaborative efforts.
15. Ensure the BIM work execution and training plans are integrated into the overall construction schedule.
16. Integrate the engineering change process and decision data into the building information model.
17. Any relevant information deviating from the supervising manufacturer’s design proposal must be submitted for review and approved by Party A before proceeding with BIM model creation or refinement.
18. Provide quick-view formats based on the BIM model, such as NAVISWORKS, DWF, I-model, etc.
19. Prepare construction drawings—such as CSD (Combined Service Drawings) and CBWD (Combined Builders Working Drawings)—for mechanical, electrical, and air conditioning integration, based on BIM models.
20. All BIM models and data generated throughout the project, including intellectual property rights, belong to the Ministry of Housing and Urban-Rural Development and relevant agencies. Without their written consent, the construction contractor must not use these materials without authorization. (Currently, most provinces and cities in China only annotate drawings; only joint construction projects in Shanghai annotate BIM models.)
What should be included in the construction party’s BIM plan? While some of these requirements may still pose challenges domestically, we believe that with joint efforts from the government and enterprises, BIM applications will continue to improve significantly.
