Underground Construction Capabilities & Qualifications
Total UC is a self-performing, Class A General Engineering contractor built for the underground scope of commercial, municipal, and residential projects across the Bay Area — water, sewer, storm, gas, and fire, from the main to the building.
Credentials That Clear Prequalification

California Contractors State License Board License #1094194 — General Engineering (Class A), the classification that covers underground utility and infrastructure work.
Licensed, Bonded & Insured
Fully licensed, bonded, and insured on every project. Bonding and insurance certificates available on request for prequalification.
Self-Performing Crew
We self-perform the critical underground work with our own crew and equipment — we do not subcontract the scope that determines whether a job is done right.

The Work We Self-Perform
Our Own Fleet on Every Job
Because we self-perform, our own operators and equipment show up on your schedule — excavators and skid steers for trenching and excavation, dump trucks for haul-off, hydro-vacuum and jetting equipment for potholing and cleaning, and camera equipment for inspection and verification.
That means one accountable crew for the underground scope instead of a chain of subcontractors — fewer handoffs, tighter scheduling, and a single point of responsibility from mobilization to backfill.
