As-Built Surveys in El Sobrante, CA

El Sobrante's valley setting along San Pablo Dam Road gives it a building mix unlike its incorporated neighbors: semi-rural lots, horse properties with barns and paddock structures, detached garages, workshops, and homes that have grown by increments over the years. Because El Sobrante is unincorporated, additions and conversions go through Contra Costa County planning rather than a city hall, and the county's plan reviewers expect submittal drawings that reflect real existing conditions. Our as-built surveys provide exactly that. Using a Trimble terrestrial laser scanner, we document every structure on the property in a single visit — main house, barn, outbuildings — and deliver DWG floor plans, sections, and elevations, Revit models at LOD 200 or 300, and the raw point cloud in E57 or RCP.

Outbuildings are where owners most often get surprised. A barn or workshop built decades ago rarely matches any drawing on file, and converting one to habitable space — or tying a new addition into it — requires knowing its true geometry: post spacing, plate heights, roof pitch, how far out of plumb the walls have drifted. Scanning captures all of it without ladders and tape, and the point cloud lets an engineer measure anything later without another site trip. On creek-adjacent and hillside-edge parcels near the San Pablo Reservoir watershed, we can extend the same scan setup to capture ground surfaces around the structures, pairing the building documentation with a topographic survey so the design team sees building and site in one coordinate system. Recorded maps and deeds for these parcels are kept by the Contra Costa County Recorder and County Surveyor in Martinez, and we research them whenever the project also needs property-line certainty.

One visit, true geometry, deliverables the whole team can use — that is the standard we hold every El Sobrante as-built to.
