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
Class A General Engineering
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.
OSHA-Compliant Safety
OSHA-compliant excavation, shoring, and trench-safety procedures on every dig. Safety documentation available on request.
Bonding capacity, certificates of insurance, and safety records are provided directly to general contractors and agencies during prequalification. Request our qualification package →

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.
