Construction and implementation of a collaborative design platform based on BIM

The existing collaborative design platform fails to maintain the coordination efficiency among different design disciplines, and there are problems such as data integration conflicts and insufficient coordination and communication. In response to this, a collaborative design platform combining building information modelling with geographic information system (GIS) was studied and constructed. In the construction process of the collaborative design platform, a multi-head self-attention mechanism is adopted for multi-parameter collaborative processing. The experimental results show that the hybrid data integration method achieves integration delay control within 8 min without manual intervention, while the integration delay control of the three multi-source heterogeneous time series, iterative fuzzy clustering, and line-based integration methods exceeds 12, 20, and 25 min, respectively. When assessing the risk factors of decision making, the risk probability rating is 0.3, and the consequence rating after the risk occurs is 0.2. In the construction schedule scheduling experiment, when the construction unit was (2,3), the actual completion time was 30 days, which was less than the recommended time. The collaborative design platform proposed in the research can improve the construction efficiency. This research is conducive to enhancing the efficiency of future collaborative management modules and promoting real-time management and design.
