The commissioning of larger structures has grown ever more complex. Buildings have more integrated systems and owners require more and better information for the operation and maintenance of their buildings. If you build for the Department of Defense (DoD) or the General Services Administration (GSA) of the Federal Government, the builder must supply a Building Information Model (BIM) as part of the turnover process.

Laser scanning of new construction can radically change the time, cost, and value of commissioning.

First, laser scanning can verify that the building was built according to design. Any discrepancies can be identified within hours, even for large, complex structures. 

Second, because laser scanning produces a 3-dimensional, virtual duplicate of the building, builders can deliver 3D, electronic, as-builts instead of PDFs or 2D drawings. Here’s a screen shot of laser scanned MEP. (It’s not a photograph.) 3D images are much easier for anyone to examine than 2D drawings.

Third, because the laser scanning data is an electronic model, all the components in the entire model can be linked to other information including the manufacturer’s web site and specifications, maintenance reports, et al.

Fourth, all BIMs start with a model of the structure, and the fastest, most efficient method to prepare the base BIM model is laser scanning. Laser scanning is accepted by both the DoD and GSA as a method to prepare the base BIM model.
