Excavation & Site Work
Grading, trenching, utility installation, and site preparation with our own heavy equipment fleet.
From rough grading to precision trenching for underground utilities, Peck General handles all site work in-house with our own excavators, loaders, and haulers.
Lack of Functional Space
Your facility or home no longer supports your mission or lifestyle.
Outdated Safety Code
Legacy structures often lack Title 24 compliance and modern fire-life safety.
Structural Cracks
Foundation settling or wall shifts indicate critical structural fatigue.
Inefficient Layout
Poor workflow in commercial kitchens or warehouses drains your productivity.
Rough & Finish Grading
Pad preparation, drainage establishment, and final grade for foundations.
Utility Trenching
Water, sewer, gas, electrical, and communications trenching and backfill.
Foundation Excavation
Precision excavation for footings, caissons, and grade beams.
Hauling & Disposal
Dirt export/import, debris hauling, and compaction testing.
Heavy Commercial Excavation and Site Work
The success of any monumental commercial build is entirely determined before the first yard of concrete is ever poured. If the foundational earthwork is flawed, the entire structural integrity of the resulting building is fatally compromised. Southern California terrain presents intense engineering challenges, from coastal sandy loams to violently expansive clay soils further inland. We provide heavy commercial excavation, precise structural grading, and rigorous site preparation to guarantee an immovable foundation for your development.
Mass Grading and Earthmoving
Transforming raw, uneven topography into a perfectly flat, buildable commercial pad requires massive heavy iron and strategic engineering. We deploy a fleet of bulldozers, articulated scrapers, and heavy excavators to execute aggressive cut-and-fill operations.
We don't merely push dirt around. We rigorously analyze the geotechnical soil reports, actively managing the moisture content of the soil and utilizing heavy vibratory compactors to achieve the strict 95% relative compaction density required by commercial structural engineers. This prevents the devastating differential settlement that ultimately cracks massive concrete slabs and destroys foundations years after construction finishes.
Deep Utility Trenching and Shoring
Commercial developments require sprawling underground utility networks. Routing massive fire-mains, high-voltage primary electrical conduits, and deep-gravity sewer laterals requires significant excavation.
Digging deep trenches in active soils is inherently dangerous. We operate under uncompromising OSHA safety protocols, deploying advanced hydraulic shoring systems and trench boxes to protect our operators and your project from catastrophic trench collapse. We coordinate flawlessly with the underground wet and dry utility contractors to ensure the trenches are cut to the exact specified depth and pitch, backfilled with the correct shading material, and compacted perfectly to grade.
Over-Excavation and Soil Remediation
In regions with highly expansive clay—which swells violently when wet and shrinks when dry—pouring a foundation directly on native soil is structural suicide. We perform massive over-excavation (scarification), physically removing several feet of unstable native soil beneath the building footprint.
We then either chemically treat the soil or import stable, engineered structural fill dirt, meticulously re-compacting it in strict 8-inch lifts until a rock-solid, non-expansive building pad is achieved.
The Peck Operational Advantage
Executing heavy excavation requires fluid logistical control over dump truck routing, environmental SWPPP (Stormwater Pollution Prevention Plan) compliance, and strict dust mitigation to avoid severe municipal fines. As a veteran-operated general contractor, we manage this chaos with military precision.
