As-Built Surveys in Orinda, CA

We deliver laser-scanned as-built surveys across Orinda in Contra Costa County — precise existing-conditions floor plans, elevations, and Revit models for the mid-century hillside homes now going through their second and third rounds of remodeling.

As-Built Surveys in Orinda: Local Conditions

Orinda literally gave its name to the geology that shapes remodels here: the Orinda Formation, a weak siltstone and claystone unit that hosts slow-moving landslides throughout the East Bay hills. Much of the town's housing was built in mid-century subdivisions on cut-slope lots carved into that material, and decades of gradual movement leave their signature inside the house — hairline-out-of-level floors, walls leaning a fraction of a degree, additions that no longer meet the original structure cleanly. When owners of these homes hire an architect to remodel or expand, the original tract drawings (if they survive at all) describe a building that no longer quite exists. Our as-built surveys close that gap by documenting the true, current geometry before design begins.

We scan the entire home — interior rooms, crawl-space perimeter, facades, rooflines — with a Trimble terrestrial laser scanner in one visit. That matters on Orinda's semi-rural large lots and winding roads, where coordinating repeat site access for a conventional measure-up wastes everyone's time. The point cloud captures millions of points at survey-grade accuracy, so a room that has racked out of square is recorded as it actually is, not forced back into a drafted rectangle. Deliverables follow your team's workflow: dimensioned CAD floor plans, building sections, and exterior elevations for permit sets, or a Revit model at LOD 200 or 300 for architects designing the addition directly in BIM. Retrofit engineers evaluating foundations on creep-prone ground get floor-level data precise enough to quantify how much the structure has actually moved.

We also deliver the registered point cloud in E57 or RCP format, letting your consultants pull any dimension later without scheduling another trip up the hill. As-built drawings themselves are design documents rather than recorded instruments, but where our work touches boundary evidence — tying the building footprint to property lines for a setback exhibit, for example — California B&P Code §8771 governs, and any required Corner Record or Record of Survey is filed with the Contra Costa County Surveyor and Recorder in Martinez.

  • Ideal for buildings with no surviving original drawings

Our Process

1

Scope the Deliverable

We confirm what your design team needs — 2D plans, sections and elevations, a Revit model, or the point cloud itself — and the level of detail required.

2

Laser Scanning

We scan the building interior, exterior, and site with a Trimble terrestrial laser scanner, typically in a single visit, capturing every surface as millions of measured points.

3

Registration & QC

Individual scans are registered into one unified point cloud and checked against control for accuracy before any drafting begins.

4

Drafting & Modeling

We extract the deliverables from the point cloud — CAD plans, sections, elevations, or a Revit model — with the cloud available to your team for verification.

As-Built Surveys in Orinda: FAQ

Yes — this is exactly what laser scanning does well. The point cloud records floor elevations continuously across every room at millimeter-level precision, so we can map slope and deflection rather than spot-check a few points. Architects use this to plan leveling, and retrofit engineers use it to assess how much movement the Orinda Formation ground beneath the house has actually caused.
That is common for mid-century tract homes here. From a single scan visit we produce a complete existing-conditions set: floor plans, exterior elevations, building sections, and roof geometry, in CAD or as a Revit model. You end up with better documentation than the original builder ever produced, because it reflects the house as it stands today.
No — as-built drawings are working documents for your design team and permit application, not recorded maps. However, if the project also needs the building located relative to property lines and we set or find monuments in the process, B&P Code §8771 may require filing a Corner Record or Record of Survey with the Contra Costa County Surveyor, which we prepare and file.
