As-Built Surveys in Walnut Creek, CA

Walnut Creek's downtown has grown into one of the East Bay's strongest condominium and mixed-use markets, and that growth generates steady demand for as-built documentation. Condominium conversion projects need floor plans accurate enough to define the units being conveyed: under the Davis-Stirling Act, a condominium plan describes three-dimensional airspace, and the diagrammatic floor plans behind it are only as good as the measurements they rest on. Our Trimble terrestrial laser scanner captures every unit, corridor, and common area in one coordinated visit — millions of survey-grade points that resolve wall positions and ceiling heights to the millimeter — and we carry that geometry through the condominium conversion mapping under the Subdivision Map Act.

The retail and office core around the Broadway Plaza area drives a second stream of work: tenant improvements in buildings whose drawings have drifted from reality through decades of successive build-outs. A scan of the demised space gives the TI architect verified backgrounds — structure, storefront lines, ceiling grids, visible MEP — delivered as DWG/DXF plans, a Revit model at LOD 200 or 300, or the E57/RCP cloud, so design starts from what exists rather than from the landlord's aging CAD file. Out in the postwar ranch tracts, remodels and additions get the same treatment at house scale; ranch homes read as simple but hide additions-upon-additions that only honest measurement untangles. Lots backing the city's creek corridors or climbing the hills at the edges often pair the as-built with a topographic survey from the same fieldwork.

Because the full building lives in the archived cloud, late-design questions never require a return visit. Walnut Creek is in Contra Costa County, so condominium plans, parcel maps, and records of survey are filed through the Contra Costa County Surveyor and Recorder.
