As-Built Surveys in Kensington, CA
We produce laser-scanned as-built surveys for Kensington, the unincorporated hillside community in Contra Costa County — accurate floor plans, sections, and Revit models of homes that decades of slope movement have quietly pulled out of square.
As-Built Surveys in Kensington: Local Conditions
Kensington has no city hall: building permits and planning approvals run through Contra Costa County, and county plan checkers expect remodel drawings that reflect the house as it actually stands. That is a real problem here, because much of Kensington's mid-century housing stock sits on steep slopes, and the Blakemont slow-moving landslide area along the El Cerrito border is the canonical local hazard. A home that has ridden creeping ground for sixty years is rarely the rectangle its 1950s plans show — floors slope, wall corners drift off ninety degrees, and door heads rack. When an architect drafts a remodel from the original permit set, those distortions surface mid-construction as failed framing layouts and cabinet runs that will not close.
Our Trimble terrestrial laser scanner captures the true geometry in a single visit: millions of survey-grade points covering every room, facade, and roofline, without the return trips a tape-and-disto measure-up demands on a house with no square reference walls. From the point cloud we deliver dimensioned floor plans, building sections, and exterior elevations in CAD, or a Revit model at LOD 200 or 300 for teams designing in BIM. Owners who never received drawings for their home — common with Kensington's Berkeley-adjacent early stock — get a complete record. Where creep monitoring over time is the real question, our structural and slope monitoring surveys extend the same scan data into repeat-visit comparisons.
We also hand off the raw point cloud in E57 or RCP format so your architect or engineer can verify any dimension later without another site visit — valuable on Kensington's narrow streets, where parking a survey crew twice is its own project. As-built drawings are working documents rather than recorded maps, but if our fieldwork ties to property corners or replaces a monument, California B&P Code §8771 requires filing a Corner Record or Record of Survey with the Contra Costa County Surveyor, and we handle that filing.

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