During the preliminary design stage, BIM work should encompass the following tasks: establishing preliminary design models for various disciplines, conducting necessary building analyses based on these models, creating an integrated BIM model for comprehensive coordination, optimizing architectural designs through BIM insights, and generating various 2D views from the BIM models. Accordingly, the BIM deliverables for this phase should include:
1) BIM Professional Design Model: Preliminary BIM design models should be developed and provided for each discipline involved.
2) BIM Comprehensive Coordination Model: A coordination model that integrates all disciplines should be delivered, focusing on cross-disciplinary coordination and optimization through detailed analysis.
3) BIM Browsing Model: Similar to the conceptual design phase, a browsing model containing necessary engineering data should be provided, reflecting the BIM design model’s creation.
4) Building Analysis Models and Reports: Energy analysis, lighting analysis, pedestrian evacuation models, and their corresponding reports should be included. Additional analysis models and reports may be provided as needed or requested by the client.
5) Visualization Model and Generated Files: A realistic visualization model based on the BIM design, representing true dimensions, should be submitted. This includes indoor renderings, virtual walkthroughs, interactive real-time VR systems, display videos, and other visualization outputs.
6) Two-Dimensional Views Generated from BIM Models: At this stage, 2D views should focus on producing complex sectional and elevation drawings. Standard floor plans and similar views are recommended to be generated directly from the BIM models.
