vir tu a l desiGN a N d c o Ns tructi o N: G s a’ s Nati o Nal 3d-4d-Bi M p ro G raM Since the computation and validation of space (e.g., rentable area, usable area, etc) is one of the most essential business processes for GSA, the Office of the Chief Architect (OCA) has been working with a number of BIM vendors, the building industry, leading research institutions, and professional organizations to establish requirements for a spatial program BIM. The overall purpose of validating a spatial program using BIM is to efficiently and accurately assess design performance, relative to GSA space program requirements. By using BIM models, GSA can automate the spatial validation process to ensure that all designs in the Final Concept phase adhere to the spatial requirements set forth by the housing plan and program of requirements. GSA will also use this analysis to benchmark performance and generate measurement reports based upon equivalent space types and building type. A spatial program validation through BIM allows both GSA and A/Es to gain efficiencies and accuracy in measuring space. By automating spatial validation, GSA can validate space during earlier design stages with more efficiency, instead of manually interpreting all ANSI/ BOMA space measurement rules. A/Es are able to spend more time on design tasks rather than spatial calculations. The 3D-4D-BIM Program has led the modeling of spatial BIMs for selected GSA projects, developing case studies, providing technical assistance to GSA project team members, creating sample language and deliverables for spatial validation services and BIM, and developing a BIM Guide Series specific to spatial validation. GSA’s BIM Guide Series documents the best practices, lessons learned, and serves as a guide for future BIM implementation for GSA as well as the AEC industry. BIM Guide Series 02 Spatial Program Validation is a publicly available guidance to aid A/Es in their BIM modeling efforts related to spatial program validation. partNeriNG WitH BiM-autHoriNG softWare veNdors to eNsure process success In support of our spatial validation efforts, GSA has spearheaded the development of an open standard by all major BIM-authoring vendors that facilitates the exchange of spatial data. GSA hopes to leverage the use of building information modeling and interoperability between BIM programs to help project teams better validate the required spatial program. Through an open standard, project teams can freely choose which software to design the building in, while GSA can ensure that the spatial program output is consistent and accurate across all software. GSA has developed a “GSA Concept Design View” of the GSA requirements for spatial data management. This view is an open standard built upon Industry Foundation Classes (IFC) and is currently supported by Autodesk Revit and Architectural Desktop, Bentley Architecture, Graphisoft ArchiCAD, Onuma Planning System, and Solibri Model Checker. These applications have gone through several rounds of validation using a GSA test case building. Several more applications are currently in the validation process. Because of these efforts, the BIM Team received the 2006 building SMART Innovating Award from the International 2 0 0 8 tHe le ade r 35 M arcH / ap r i l
