In 2003, GSA created the National 3D-4D-BIM Program to “promote value-added digital visualization, simulation and optimization technologies to increase quality and efficiency through GSA project lifecycles and beyond.” GSA is responsible for meeting the space requirements of federal agencies along with providing buildings and construction guidelines for these resources. While adopting specific CAD standards and project requirements, GSA has also committed to strategic and incremental adoption of 3D, 4D, and BIM technologies.
