Excavation, grading & trenching in San Diego
Bernal Builders, Inc. is a San Diego general contractor that performs excavation, grading, and trenching as part of its site-work capabilities across San Diego County. We hold California CSLB License #1047688 with General Building and General Engineering classifications, and site work is coordinated alongside our structural, concrete, and foundation capabilities.
Site work is often the first construction phase on a project. Excavation and grading prepare a site, trenching supports foundations and utilities, and that work ties directly into foundations, concrete, and the structural build that follows. Coordinating these phases within one project can keep a build on track.
What site work may include
Depending on the project, Bernal Builders' site work may include excavation, grading, trenching, and site preparation, along with foundation-related excavation and construction-related trenching. We do not claim a specific equipment fleet, excavation depths, hauling capacity, soil engineering, or utility-locating services — scope is developed per project.
SDG&E-related excavation & backfill
Bernal Builders also provides SDG&E-related backfill and excavation as a Veriforce Certified and SDG&E Signatory Contractor. This is a confirmed capability related to utility excavation and backfill work. Bernal Builders does not represent SDG&E, and SDG&E does not endorse Bernal Builders.
Where site work fits in our projects
