Site work contractors take a project from raw or occupied lot to a pad ready for vertical construction. The sequence usually starts with demolition contractors clearing existing structures, after utility disconnects and any required asbestos and lead abatement, followed by grading contractors and excavation contractors who cut, fill, and compact to the civil engineer's plan. On sloped or constrained sites, shoring contractors and caisson drilling contractors come in where excavations need temporary support or the foundation design calls for drilled piers, a common condition on California hillside lots. Trenching services handle utility runs, retaining wall contractors build the engineered walls that hold grade, and foundation contractors place the footings, stem walls, or slab that close out the phase and hand off to framing. This phase carries most of a project's ground risk, so the geotechnical report belongs in every bidder's hands: it governs compaction requirements, excavation slopes, and pier depths, and a bid priced without it is a change order waiting to happen. Coordination points worth managing closely include haul-off and import quantities, since export is a major cost driver on urban California sites, dust and stormwater controls, including SWPPP coverage under the state Construction General Permit on projects disturbing an acre or more, survey staking before grading starts, and compaction testing scheduled with the soils engineer so the foundation inspection is not delayed waiting on reports. Costs vary widely by scope; soil conditions, slope, export distance, shoring depth, groundwater, and rock move the number far more than lot size does. In California this work is typically performed under CSLB classifications such as the A general engineering license or trade classes like C-21 for demolition. Before contracting, we recommend confirming that a contractor's license, bond, and insurance are current; both California and Texas publish free public license lookup tools that make the check straightforward.
After, whenever the schedule allows. The soils report defines compaction requirements, over-excavation depths, excavation slopes, and pier design, which are exactly the items that swing site work pricing. Bids taken without it come back either padded for unknowns or stripped of them, and the stripped version returns as change orders once grading starts.
Experience with comparable soil and slope conditions, owned or reliably rented equipment matched to the site's access, and a plan for export, dust control, and stormwater compliance. Confirm the bid references the geotechnical report and the civil grading plan by name. We also recommend confirming the CSLB or Texas license, bond, and insurance are current through the states' free public lookup tools.
Get the exclusions in writing before award: bids commonly exclude rock excavation, hammering, contaminated-soil export, and dewatering, and any of those discovered mid-dig comes back as a change order. A thorough geotechnical report shrinks the unknowns, and many contracts use differing-site-conditions provisions so genuine surprises are priced when encountered rather than padded into every bid. Whatever the structure, the bid should state which subsurface conditions it assumes.

Line up utility disconnects and any asbestos and lead abatement before the demo contractor mobilizes, have survey staking and the SWPPP in place before grading, and schedule compaction testing with the soils engineer as fill goes in rather than after. The foundation inspection typically needs the compaction report in hand, so a testing lag directly stalls concrete.
Shoring comes into play when an excavation is too deep or too close to property lines, structures, or streets to lay back slopes safely, which is common on urban infill and basement projects. Caissons, or drilled piers, are used where the foundation design needs to reach competent material below weak or sloping ground, a frequent call on California hillside lots. Both are driven by the geotechnical and structural design, not by contractor preference, and separately from design, federal safety rules require a protective system for excavations five feet or deeper unless they are entirely in stable rock.
