A GPRS Case Study

Water Treatment Plant Expansion Utilizes 3D Laser Scanning Point Cloud Data

I have used 3D point clouds for many years. I use the raw point cloud data to do my layouts accurately to the field conditions.

Deliverables

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.

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.
