PROJECT APPLICATION
A water treatment plant with no as-builts needed accurate existing conditions documentation to play expansions. GPRS 3D laser scanning delivered raw data that allowed team members in multiple states to collaborate.
ASK
Accurate existing conditions capture and as-built documentation for a water treatment plant expansion
Task
Capture accurate existing conditions and provide raw as-built, point cloud data for the expansion of a water treatment plant
PROBLEM
- No as-built drawings existed for the water treatment plant. Accurate existing conditions were needed to plan for the facility expansion
- Exact dimensions were required to plan modifications and fabricate pipe
- The project's engineering firm was located in California; the water treatment plant was located in Texas. They needed accurate information available in a digital platform to begin design planning
Solution
- Using a Leica Scan Station, a GPRS Project Manager completed 40 laser scans of the building to capture architectural, structural, and MEP features
- The client received a colorized point cloud in ReCap (.rcp files and related supporting files) and TruView files that allowed the engineering firm and the plant to coordinate off-site planning and prefabrication for the expansion
Benefits
- Laser scanning is an extremely efficient and accurate way to gather data necessary to create construction drawings of a building or space.
- 3D laser scanning eliminated the firm’s travel to the Water Treatment Plant. In one day on site, enough scans were taken to create a complete colorized point cloud of the space.
- 3D laser scan data provided the Engineering Firm critical tie points on tanks and lines, information that was crucial to the expansion.
