The purpose of the PBS CAD Standards is to ensure consistent 2D drawings, an accurate source of spatial data, and uniform requirements for contractor design deliverables. The standards aid our business by providing accurate space assignment and rent billing data, drawings suitable for client agency use (e.g., space planning and furniture layout), maintenance and operation data, and record drawings for management and future renovations of PBS buildings. Many of the files in the CAD Standards Library require CAD software for viewing and editing. However, if a customer does not possess such software and is in need of information provided by these files, they should contact a GSA representative for assistance.
