As-Built Surveys in Concord, CA

Concord's commercial building stock is at an inflection point. Office parks and retail centers built decades ago are cycling through repositioning, downtown parcels near BART are densifying, and industrial buildings are being converted to new uses. Nearly every one of those projects begins with the same question: what exactly is here now? Landlord files typically hold a leasing plan or a decades-old tenant improvement set — documents that have drifted far from the built reality after years of demising-wall changes, ceiling work, and mechanical retrofits. Our as-built surveys replace that guesswork. Using a Trimble terrestrial laser scanner, we capture an entire floor plate or building shell in one visit and deliver dimensioned floor plans, reflected ceiling information, sections, and elevations in DWG, or a Revit model at LOD 200 or 300 for teams working in BIM.

For tenant improvement work, speed and completeness are the practical advantages. A scan-based as-built documents every column, soffit, window mullion, and slab edge in a single pass, so the TI architect is not sending someone back to the site for the dimension nobody measured. For repositioning projects — converting retail to medical, office to flex, industrial to something else entirely — the deliverable scales up: full-building point clouds in E57 or RCP that structural and MEP engineers can interrogate directly, with clear heights, beam depths, and existing penetrations all measurable from the data. One site visit, and every discipline works from the same true geometry.

Concord also carries a mapped seismic constraint: the Concord fault crosses the city and is zoned under the Alquist-Priolo Earthquake Fault Zoning Act, which shapes what can be built or expanded on affected parcels. When a repositioning project needs the building tied to its site — boundary, topography, and structure in one coordinated dataset — we combine the as-built with survey control, and we pull recorded maps from the Contra Costa County Recorder and County Surveyor in Martinez to support the site side of the work.
