PG&E Jefferson Martin Substation, Transmission Line

San Mateo County

ANDREGG GEOMATICS was selected by the substation contractor to provide layout for the construction of the Jefferson Substation Improvements, the termination point for the Jefferson transmission line. The work involved establishing control for the site and per PG&E plans provide construction staking for the substation improvements. Field crews had to comply with PG&E's rigorous safety and environmental requirements and training since the project took place in a live substation and an environmentally sensitive area.
