Highlights
THE BOTTOM LINE
The client was able to fabricate components offsite and plan a flawless installation based on our existing condition data and 3D model. Plus, GPRS' work was conducted entirely at night, mitigating any disruption to construction

PROJECT APPLICATION
Provide accurate measurements and existing condition documentation to allow for the prefabrication and proper installation of ACM (aluminum composite material) panels to the canopy of a newly constructed airport terminal
ASK
3D laser scan a complex construction site at an airport, including a 65 ft. canopy, on which the client would be affixing prefabricated aluminum composite panels with no room for error, and provide accurate existing condition documentation and a 3D model to aid in accurate prefabrication and prevent reworks
Task
Field verification to prefabricate ACM panels
PROBLEM
- The construction plans did not match the existing conditions at the site. The installation process needed to be precisely planned to avoid rework
- The shape of the canopy was complicated and stood 65 feet in the air. The client needed field verification and a plan to expedite proper installation of the panels
- Installers were working overhead in a lift; there was no room for trial and error
Solution
- The Project Manager conducted a site walk to devise a plan for the client
- The canopy and curtain wall of the airport terminal were 3D laser scanned to capture precise as-built data and generate a 3D model and 2D drawings to facilitate ACM panel installation
- 22" x 34" 2D CAD drawings were created with the panel layout for the client to take to the field. This allowed each panel to be labeled with a custom number, cut and shim points
Benefits
- Laser scanning obtained exact measurements for the client and took away any guesswork from this project
- To circumvent the active construction site, the Project Manager scanned the site at night to eliminate movement and trades working
- The client was able to fabricate components offsite and plan a flawless installation
