Contour Survey

As-Built Surveys in Brentwood, CA

We provide as-built surveys in Brentwood, in eastern Contra Costa County, scanning agricultural buildings on legacy family parcels and newer homes slated for additions — one visit, true geometry, deliverables designers can trust.

As-Built Surveys in Brentwood: Local Conditions

Brentwood is agricultural land in transition: orchards and row crops still working beside fast-growing subdivisions, and family parcels held for generations sitting next to homes built in the last two decades. That mix produces two very different as-built needs, and we serve both. On the ag side, barns, packing sheds, shops, and farmstead houses on older parcels often have no drawings at all — yet owners repurposing them, adding to them, or documenting them for estate and planning purposes need accurate records. On the residential side, owners of newer Brentwood homes planning additions discover that builder plans rarely match the house as actually constructed. In either case, our Trimble terrestrial laser scanner captures the structure completely in one visit, and we deliver DWG floor plans, sections, and elevations, Revit models at LOD 200 or 300, and the point cloud in E57 or RCP.

Agricultural buildings reward scanning in particular ways. Long-span roof framing, pole and post spacing, lean that has accumulated over decades, equipment clearances — all captured as measured geometry an engineer can rely on before designing a conversion or a structural repair. And because many legacy Brentwood parcels are described by metes and bounds and carry irrigation easements, building projects here often raise land questions alongside building questions: where the easement runs relative to the barn, whether an addition stays clear of a line. Recorded deeds and maps answering those questions are held by the Contra Costa County Recorder and County Surveyor in Martinez, and as licensed surveyors we research them routinely, adding a boundary and topographic survey to the as-built scope when the design needs it. For newer homes, the value is simpler: an addition designed against scan-accurate existing drawings avoids the framing surprises that stall projects mid-construction.

Whether the subject is a century-old barn or a five-year-old house, the standard is the same — the building documented as it truly stands.

  • Catches out-of-square rooms and sloping floors tape measures miss
  • 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 Brentwood: FAQ

Start with an as-built survey. We scan the barn in one visit and produce plans, sections, and elevations your architect and engineer can design against — post spacing, plate heights, roof geometry, and accumulated lean all measured, not assumed. If the conversion raises setback or easement questions on your metes-and-bounds parcel, we can research the recorded documents in Martinez and add boundary work.
Builder plans document intent, not the finished house — field changes, framing tolerances, and undocumented revisions are normal even in recent construction. Scanning takes a few hours and gives your designer the actual dimensions, which prevents the classic mid-construction discovery that the new roofline or floor level does not meet the old one where the plans said it would.
Yes, as an added scope. Easements are established from recorded documents held by the Contra Costa County Recorder in Martinez, so locating one on the ground is boundary-survey work rather than building documentation. We combine the two on one coordinate system, so your site plan shows the buildings and the easement in their true relationship.
