Structural Workflow - Semi-Social BIM

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.

Is this something we really want to do? Creating fabrication drawings (shop drawings) is a step in the quality control process...

I do know what you're saying, but there has to be a place in between blinding accepting files and remodeling each and every piece, as discussed here. http://bimx.blogspot.com/2009/08/rfis-and-submittals.html

Did the detailer cut their fee and pass on the savings to the S.E., or the owner? Or do they just pocket the difference?

Sean,

I'm a structural engineer that the detailer-as-qc method (let them try to build it, and find my mistakes or omissions) is a bit of a cop-out.
As SE's, we should push to recoup the cost of modeling from the downstream parties who will benefit from our extra work and attention to detail- the fabricators, detailers, and construction managers. Maybe though BIM it will eventually make sense for the SE to do more of the detailing, like they do in other countries. We just need to structure the contract in a way that we can do this and still profit.
