It’s always interesting to see some statistics that back up claims about products and processes. The enthusiasm over Building Information Modeling (BIM) has often been punctuated by claims that are drawn from logic and extrapolation rather than actual experience.
Holder Construction built the recently-opened Aquarium Hilton Garden project in downtown Atlanta finishing it in March 2008. According to a press release put out by Vico Software, makers of 5D Virtual Construction software and attendant services, the project achieved some collaborative and economic results.
Everyone on the team had the chance to literally walk-thru the building before a bucket of dirt was moved. But where the process really hit some savings was in the reduction of change orders by eliminating “collisions” that result from design discrepancies. You are all familiar with them, and some of them sound like this when the people doing the work are bringing them to your attention:
HVAC needs to move the duct work three inches to the left so we can get a conduit through there.
By using BIM for this project it is claimed that 590 collisions were avoided and that saved $800,000.
I’ll bet a lot of people got new tape measures out of that deal.
