  • 1.  Design- Build and BIM Coordination Model

    Posted 05-01-2025 05:25 PM

    Our Design-Build partner is asking us to sign-off on the coordination model. The BIM execution plan already indicates the model coordination is the Trade Contractor's responsibility & they need to sign off. Anyone have any experience w/ this request. Seems they are treating this as a "submittal" rather than a coordination tool.

    I hope your contract documents do not stipulate that the contractor's BIM Model is a contract document nor that the contractor's BIM model is a submittal for A/E review. The contractor's BIM model for construction is their tool, it is not prepared under your supervision, and it is not one of your "instruments of service." 

    Maybe the points in the following two (2) AIA documents will provide you with some guidance and a few discussion points as to why you must not sign off on the contractor's BIM model. Check out these 2 documents........

    • AIA E402-2022 BIM Exhibit for Sharing Models Solely Within the Construction Team.  
    • AIA E201–2022, BIM Exhibit for Sharing Models with Project Participants, Where Model Versions May be Enumerated as a Contract Document

    Also, check out this link.............. BIM as a Contract Document: AIA's Innovative Solutions

    I hope this is helpful.

    To all,

    Please remember that the recognized and established legal Standard of Care is that: Architects are not responsible for the means and methods of construction or implementation of the Contract Documents. 

    The BIM model is a means and methods produced by the GC, CM or Owners' Rep. The BIM model is not a Contract Documents and must be coordinated and amended to the Construction Documents as an a separate service to the Administration of the Construction Contract.  

    Do not step back architects. Contractors agreed to build according to your Construction Documents, not their creations.
