LA Fuess, who hosted the BRUG meeting, also presented on one of their projects.
On this project they were only design team member to work utilize VDC (although now they are working with Revit-enabled architects on about 20% of their projects). The contractor, a JV between Austin and Walsh, utilizes BIM, but initially wasn't sure if they could trust the accuracy of LA Fuess' model.
In the end, LA Fuess proved that their model was accurate and detailed enough for use in coordination and fabrication-assistance. They actually added geometry (like gusset plates) at the request of the contractor (a lesson to all of us: ask and you shall receive).
The model was transfered to the fabricator for detailing, and the information was so beneficial to the fabricator that it cut down the detailing schedule by 2 months.
