The team refined guidelines in the BIM. The pilot projects also reinforced the GSA BIM Team’s assessment that the A/Es would be able to integrate this requirement into their current business processes. On the Tuttle Courthouse Annex project in Atlanta, the architect’s initial submission contained several inaccuracies, including outdated nomenclature and ignoring wall thicknesses in usable area calculations. The GSA BIM Team worked with the architect to clarify submission requirements, resulting in a model that was more accurate in space measurement. A single BIM model can be used for customer visualization and automatic generation of customized, color-coded floor plans. From this model, the GSA BIM team can validate the spatial program used to validate space and rent, and create a customized BIM report (see Figure 1). Through collaboration and consensus with other organizations on technology standards and guidelines GSA can ensure replication by other organizations. For example, the GSA BIM Guide Series (www.gsa.gov/bim) on Spatial Program Validation was chosen as the foundation for the National BIM Standard, and the BIM Guide Series on 3D Imaging will serve as the foundation of the ASTM Laser Scanning Standard. GSA’s National 3D-4D-BIM Team collaborates with leading industry consultants and software developers, standards committees, academic and research institutions, as well as other U.S. and international government agencies to receive broad feedback and consensus, which enables the Program to adjust its activities accordingly in response to industry-wide maturity and further advances in these technologies. Ongoing collaborations include development of standards with National Institute of Standards and Technology (NIST), National Building Information Modeling Standard (NBIMS), and American Society for Testing and Materials (ASTM).
