Contour Survey

As-Built Surveys in San Pablo, CA

We produce as-built surveys in San Pablo, one of Contra Costa County's oldest communities, documenting existing buildings with a Trimble terrestrial laser scanner so remodels start from true geometry rather than guesswork.

As-Built Surveys in San Pablo: Local Conditions

San Pablo sits at the heart of the Mexican-era Rancho San Pablo, and its housing stock reflects a long, layered history: a small, dense city of older flatland homes along and around the San Pablo Avenue corridor, many of them expanded, converted, or repaired over decades without a single reliable drawing surviving. When an architect is asked to design a remodel or addition for one of these houses, the first problem is rarely design intent — it is that nobody knows what the building actually measures. Our as-built surveys solve that. We capture the structure inside and out with a Trimble terrestrial laser scanner, collecting millions of survey-grade points in one visit, then deliver dimensioned floor plans, sections, and elevations in DWG, Revit models at LOD 200 or 300, and the registered point cloud itself in E57 or RCP format.

Older San Pablo homes are exactly where tape-and-sketch measuring fails. Walls drift out of square, floors slope, additions meet original framing at odd angles, and ceiling heights change room to room. The scanner records all of it as measured fact, so the drawings your designer works from show the building as it stands — not as someone assumed it was built. Because the point cloud is a complete record, questions that come up months into design ("what is the header height at that opening?") are answered from the data, not a return trip. Original permit drawings, when they exist at all, live with city or county archives, and recorded maps for these old rancho-derived parcels are held by the Contra Costa County Recorder and County Surveyor in Martinez — we are comfortable working in both worlds, and as a licensed firm we can pair the building documentation with a boundary and topographic survey when an addition needs to hold setbacks.

Deliverables are matched to the team using them: 2D CAD for a straightforward kitchen-and-bath remodel, a full Revit model for a substantial reconfiguration, point cloud for the consultant who wants to verify anything independently.

What's Included

  • Trimble laser scanning captures true existing conditions
  • Floor plans, sections, and elevations from one site visit
  • Revit/BIM models at LOD 200 or 300
  • Point cloud deliverables in E57 or RCP format
  • 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 San Pablo: FAQ

Yes — that is the core purpose of an as-built survey. We laser scan the building as it exists today and draft floor plans, sections, and elevations directly from the point cloud, so no prior drawings are needed. For older San Pablo homes with multiple past alterations, this is usually faster and far more accurate than trying to reconstruct history from permits.
Most single-family homes are scanned inside and out in a single visit, often within a few hours. The Trimble scanner captures millions of points per setup, so we spend one efficient day on site and do the drafting work back at the office — minimal disruption to an occupied house.
No. An as-built survey documents the building itself — its geometry, dimensions, and features. A boundary survey establishes property lines from recorded maps and monuments, with records held in Martinez for Contra Costa County parcels. Additions in San Pablo often need both, and we can deliver them together on a shared coordinate basis.
