Client: Sanitation Districts of Los Angeles County

Location: Cerritos, CA

The Sanitation Districts of Los Angeles County contracted the WestLAND Group to provide high resolution surveying and scanning of the Los Coyotes Water Reclamation Plant in Cerritos.  The underground galleries needed to be mapped at a precision high enough for their engineers to perform electrical conduit routing designs and conflict analysis. The WestLAND survey crews tied into existing 3D site control, established new control underground and scanned approximately 550 feet of tunnels and galleries in one day rather than the estimated 5 to 6 days using traditional survey techniques.

WestLAND personnel then took the raw data from 27 scans, brought it into FARO Scene software registering the 3D point cloud to meet the 6mm (0.02’) precision, and exported the required POD and E57 files for the clients use. A full survey control report accompanied the large data set on a thumb drive for delivery. The final product is saving the client numerous expensive trips to the field to capture measurements; now the client simply opens the 3D point cloud and makes measurements at their desk.
