As-Built Surveys in Hercules, CA

Hercules began as the company town of the Hercules Powder Company, and that history left the city an unusual mix of buildings to document. The surviving company-town cottages are more than a century old, built to house dynamite-works employees, and today they sit in a city that values their character — which means remodels and rehabilitations that need careful existing-conditions documentation, not demolition-and-replace assumptions. Our as-built surveys capture these cottages with a Trimble terrestrial laser scanner in a single visit, producing dimensioned floor plans, elevations, and sections in DWG that record the true geometry: settled foundations, racked door openings, additions grafted on over decades. For rehabilitation work where preserving the original fabric matters, drawings that reflect what actually exists are the foundation of good design.

The rest of the city is younger — waterfront-district development on former industrial land and master-planned neighborhoods from recent decades — but as-built needs arise there too. Newer homes get remodeled, commercial spaces get re-tenanted, and even recent construction often lacks accurate record drawings once field changes and tenant improvements accumulate. A scan-based as-built resets the record. We deliver DWG plans for straightforward remodel work, Revit models at LOD 200 or 300 for design teams in BIM, and the E57 or RCP point cloud whenever an engineer wants to verify conditions directly. Because the waterfront district sits partly on bayfront fill, structural work there sometimes intersects state-mapped liquefaction zones under the Seismic Hazards Mapping Act — a site-level question we can flag alongside the building documentation.

Land records for Hercules — recorded maps, deeds, and filed surveys — are maintained by the Contra Costa County Recorder and County Surveyor in Martinez, and we research them whenever an as-built project also needs boundary or setback answers. For projects that want building and site in one dataset, our laser scanning services tie both to a common coordinate system.
