City of Vancouver Air Scrubbers

The City of Vancouver contracted Brown and Caldwell to add structural support to the top component of its air scrubbers. To design the support structure, Brown and Caldwell had Epic Scan gather 3D point cloud data and provide virtual site access (VSA) for the air scrubber. Scanned components included structural, architectural, electrical and mechanical items. Epic Scan’s accurate as-built information on existing conditions enabled Brown and Caldwell to engineer an efficient solution.
