Experimental BIM Use Comparison on Stanford Hospital Cath Labs

Published on

This presentation is a cost comparison between three nearly identical projects where the only variable is the use of BIM. The first cath lab was delivered using a traditional CAD approach, the second cath lab used industry standard BIM (modeling objects down to 2"), and the third cath lab modeled everything including studs and outlet boxes. The change order rates dropped to practically nothing but the costs were a bit surprising.
