One of the early presentations at the BIMForum meeting discussed the use of structure model on Solaris, a 420~,000 SF mixed used project in Vail, discussed by Wayne Muir (President of Structural Consultants Inc.) and Chris Allen, (Manager of VDC at Weitz). The structural model was used to a great degree on the project, and many specific noteworthy points were brought up. I will touch on just a few of them in a few posts.
On the project, SCI (the structural engineer) contracted directly with the owner, and it was determined that the model would be used by both design and construction team members.
Because of the modeling during design, SCI delivered more accurate information to the construction team during DD. In fact, at DD, the deliverables for Weitz and the subcontractors was drawings, specs AND the 3D model. And for specific components (for instance, the complex roof structure), the model governed when there were discrepancies between the model and drawings.
The metrics: Sub bids for the steel package, budgeted at $30,000,000, were within $100,000 of each other. Sub bids for the precast package, budgeted at $8,000,000, were within $5,000 of each other.
