Pipeline Safety Enhancement Program

Client: Southern California Gas Company

Location: Mojave Desert, CA

WestLAND Group has various on call contracts with Southern California Gas Company to provide survey and engineering services in support of their mutli-year program to replace and upgrade various pipelines throughout their service territory.

WestLAND was responsible for all construction surveying and as-built surveying & mapping for a 30″ high pressure transmission gas pipeline remediation project. The project consisted of various pipeline relocations, replacements and repairs for approximately 120-miles across the Mojave Desert. WestLAND established a static GPS/GNSS control network along the entire pipeline alignment, performed public land boundary surveys to establish section corners and lines, and provided construction staking for pipeline alignment and right-of-way limits at various locations throughout the project. WestLAND survey crews also performed as-built surveys throughout the pipeline construction process to collect all pipeline features, such as welds, elbows, valves, etc. and generated as-built plan and profile drawings along with GIS/survey data files to be incorporated into existing GIS databases.
