TruePoint was contracted to provide 3D scanning services for a 10-story office building to document the existing above-ceiling interstitial HVAC systems across each floor, as well as mechanical rooms, chiller rooms, air handling unit rooms, and a basement tunnel connecting the utility area to the main office building. Over 240,000 square feet of space was meticulously laser scanned to capture the as-is conditions, facilitating the client's HVAC system upgrade. The data collected was used to develop a 3D model to aid the design process and minimize clashes during the upgrade.
