Currently, BIM technology is primarily applied during the design and construction phases of projects. In the design phase, it enhances the professional capabilities of designers, while in construction, it positively influences project timelines and costs. For designers, the value of BIM technology is evident in several key areas:
The design team’s use of BIM technology centers on collaborative design, which enables early detection of design conflicts and flaws, optimizes design solutions, reduces changes during construction, and allows for efficient on-site resource allocation. Using BIM models, the design team creates comprehensive professional information databases through the following process:
First, the architect develops a basic model that serves as a foundational framework for other specialized models. Next, structural, plumbing, HVAC, and electrical engineers collaborate with the architect to enrich the model’s information. The structural engineer builds the structural model based on the initial architectural model and works closely with the architect to refine it. Mechanical and electrical engineers then add detailed information related to plumbing, HVAC systems, and electrical supply and distribution.
Finally, the BIM model information undergoes clash detection to identify any conflicts between the different professional models, such as pipeline clashes. Once the clash detection confirms no conflicts, construction drawings can be directly generated. If clashes are found, each discipline revises the model design to resolve the issues based on the clash detection results. This iterative process continues until all conflicts are eliminated. For particularly complex nodes with challenging construction requirements, further adjustments in collaborative design may be made to ensure accuracy and feasibility.
