The Evolution of 3D Surveying at MWD – Over a Decade of Scanning for Water Infrastructure Reliability

The Metropolitan Water District (MWD) of Southern California is a regional wholesaler that delivers water to 26 member public agencies – 14 cities, 11 municipal water districts, and one county water authority which in turn provide water to more than 19million people in six counties. MWD imports water from the Colorado River and the Feather River in Northern California to supplement local supplies, and helps its members to develop increased water conservation, recycling, storage and other local resource-management programs. To supply its member agencies with reliable and safe water, MWD owns and operates an extensive water system which includes the Colorado River Aqueduct, nine reservoirs, more than 800 miles of large diameter pipeline, five large water treatment plants, and sixteen hydroelectric facilities. MWD Survey (MWDS) supports MWD’s Engineering and Operations Groups by providing a broad range of land surveying and geospatial mapping services throughout MWD’s 5,200 square-mile Southern California service area. MWDS started 3D scanning in 2002 by purchasing one of the first laser scanners designed for surveyors, the Cyrax 2500. The scanner was mainly utilized to perform topographic surveys and to supplement traditional survey methods and increase efficiency and safety on civil/survey projects. Since then, MWDS has acquired two Leica C10 ScanStations, a Z+F 5010C phase-based scanner, and a Creaform HandyScan700 hand-held scanner. Over the years, MWDS has augmented its services and workflows to include a robust 3D surveying program, which now supports a large portion of survey projects for Engineering and Operations. This presentation will cover the evolution of 3D surveying at MWD, including current workflows and deliverables, and how it has transformed from a supplemental surveying tool into a primary method of 3D data collection and documentation. MWDS now uses 3D surveying technology on various project types, ranging from civil design surveys and precise mechanical 3D modeling projects to more unique applications, such as large tunnel surveys, dam deformation monitoring, pipeline inspection surveys, construction as-builts, reverse engineering and quality control for manufacturing purposes, and visual asset mapping surveys. The presentation will exhibit a number of unique 3D deliverables prepared using various software platforms, including Microstation, Leica Cyclone & TruView, 3D Reshaper, Creaform VXModel, and SolidWorks.
