NSU Storm Drain – San Diego, CA
This design-bid-build project installed 7,000 LF of storm drain pipeline and a new pump station to mitigate stormwater issues at the San Diego International Airport. This project presented several distinct challenges unique to working at airports and in high water table areas. Orion worked closely with the airport authority to mitigate impacts to airline operations. Substantial dewatering was needed as groundwater was at or above 5ft throughout construction.
The complexity of this project required a multidisciplinary heavy-civil construction approach which utilized commercial scuba diving, directional drilling, paving of access roads, and deep excavations.
