|Abstract:||The General Services Administration's (GSA) Public Buildings Services manages 1600 buildings totaling 180, 000, 000 square feet. GSA‰s ability to capture, validate, and report the spatial information of its building assets (e.g., dimensions, areas, and locations of rooms; elevation details; HVAC and ductwork, etc) affects how GSA conducts its core business. To this end, GSA has been conducting pilot projects using 3D imaging systems to determine the efficacy of 3D imaging to capture and model existing conditions. The raw output of a 3D imaging system is in the form of point clouds (clouds of points numbering, typically, in the millions) which may be imported to CAD applications. The raw data are often post-processed to produce 2D documents (e.g., drawings, plans), 3D geometric models, and building information models (BIM).|
