Highlights

THE BOTTOM LINE

With 3D laser scan data, the client can accurately verify the existing HVAC and mechanical equipment within the building without having to worry about positioning or measurement error. This helps them to design their new systems more accurately and efficiently.‍

Deliverables

GPRS delivered point cloud data in .rcs file format usable in Autodesk products (Revit, AutoCAD, Navisworks, etc.) so the client can align and overlay the point cloud to their existing 3D Revit model to verify the location of large format ductwork located in the interstitial space. GPRS also provided a 3D model of the mechanical rooms, chiller rooms, air handling unit rooms and basement tunnel. An LOD 100 model of the structural space and an LOD 300 of the MEP space was delivered to the client.

Task

3D scanning services were performed for a 10-story office building, capturing existing above-ceiling interstitial HVAC systems on each floor, as well as mechanical rooms, chiller rooms, air handling unit rooms and a basement tunnel connecting the utility area to the office building. Over 240,000 square foot of space was laser scanned to document the as-is conditions. The client was upgrading the HVAC system and GPRS developed a 3D model to aid the design process and reduce clashes.

PROBLEM

With the site being an active office building, it was critical that the required LiDAR scanning data was obtained with minimal interruptions. Accuracy was important and the space was vast, they needed complete documentation to plan for system upgrades, including above the acoustic tile that was to remain in place.

 

Solution

Using the Leica P40 and Leica RTC360 3D laser scanners, GPRS Project Managers 3D laser scanned the interstitial and mechanical space in the evenings to avoid interrupting the office workday. A laser scanner mounted to a tripod was extended above the ceiling tiles to capture the interstitial space. With the 3D laser scan data, the client can accurately verify the existing HVAC and mechanical equipment within the building without having to worry about positioning or measurement error. This enables them to design their new systems more accurately and efficiently.

Benefits

GPRS customizes deliverables for each client, so they are only paying for what they need. Also, upon completion of the HVAC system upgrade and prior to ceiling tiles being installed, GPRS will re-mobilize to the site to capture the new as-built conditions of the space for future reference.
