hundreds, if not thousands requests for information are required. However, using BIM effectively can dramatically improve the ability to share data, which results in a significant reduction in RFIs. • Rework – When the building is first designed in a virtual environment, the detailer is able to verify that various elements converging on one point fit together properly. The A-3 rocket test stand at Stennis Space Center in Mississippi, has up to 16 different structural members connecting at one point, requiring a very slim margin of error. However, thanks to 3D modeling, less than 1% rework of all connections had to be performed in the field (Weisenberger, 2009). • Collaboration - Under a traditional design-bid-build contract, designs are moved sequentially from architect to engineer to fabricator, with little interaction until the
