Services: Excavation of Tunnel for Plumbing Repairs
TUNNEL EXCAVATION - SAN FRANCISCO, CA
ESR was approached to excavate an underground tunnel to allow a condominium complex to make plumbing repairs. The job involved creating access through the underground garage slab floor at 12 locations. The tunnels were excavated by hand. In addition, we installed ventilation, lighting and a dewatering system. The sides were shored to allow the tunnels to remain in place for future maintenance. Once the plumbing repairs were complete, the access holes were sealed with concrete.
Job Duration - 4 Months (including time for plumbing repair)
