As-Built Information and Laser Scanning Utilized laser scanning for determining existing conditions… 1. Obtains fast, accurate results of as-built information. 2. Provides complete measurement data of Scanning To Model Coordination the entire surface of the interior and exterior spaces and surfaces. 3. Incorporates the information into CAD and BIM models where no model exists. 4. Develops data of the whole so assemblies can be digitally put together in BIM, revealing inaccuracies and interferences.
