As-Built Surveys in Martinez, CA

We produce laser-scanned as-built documentation for buildings in Martinez, the Contra Costa County seat, where much of the downtown commercial stock predates any surviving construction drawings.

As-Built Surveys in Martinez: Local Conditions

Martinez's downtown grid was platted in the 1800s along the Carquinez shoreline, and it shows in the buildings: brick and timber commercial blocks that have been re-partitioned, re-roofed, and re-faced over more than a century. When an owner or architect starts a renovation on Main Street, the first problem is almost always the same — there are no reliable drawings. Original plans are gone, and what does exist rarely matches what was actually built. Our as-built surveys solve that starting condition. We capture the entire building with a Trimble terrestrial laser scanner in a single visit — millions of survey-grade points recording every wall, opening, ceiling height, and floor deflection — and deliver dimensioned floor plans, sections, and elevations in DWG, or a Revit model at LOD 200 or 300 when your project is heading into BIM.

Old downtown Martinez buildings are exactly where scan-based as-builts outperform tape-and-disto measuring. Walls in these structures are rarely plumb, floors are rarely level, and party walls between adjacent storefronts often wander. Hand measurement averages those irregularities away; the point cloud preserves them, so your remodel documents reflect true geometry rather than an idealized rectangle. That matters for tenant improvements, seismic retrofit design, and accessibility upgrades, where an inch of discrepancy discovered during construction is far more expensive than an inch documented up front. We deliver the raw point cloud in E57 or RCP alongside the CAD or Revit files, so your engineer can verify any dimension directly against the scan data.

Because Martinez is the county seat, the Contra Costa County Recorder and County Surveyor offices are located right here, and we routinely pull recorded maps for downtown parcels — useful when a renovation also needs the building located relative to its boundary, since recorded maps document lot lines, not building interiors. For projects that pair interior as-builts with site work, see our 3D laser scanning services.

  • 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 Martinez: FAQ

Yes — that is the core of what an as-built survey does. We laser scan the existing building and draft new floor plans, sections, and elevations directly from the point cloud, with no dependence on prior drawings. For Martinez's 19th- and early-20th-century commercial stock, this is usually the only way to get accurate base documents for a renovation.
It will. The Trimble scanner records actual geometry — leaning walls, sagging floors, irregular party walls — rather than assuming square corners. We can deliver true-geometry drawings or rationalized plans with deviation notes, whichever suits your architect's workflow, and the E57 point cloud lets your team check any condition themselves.
No. Maps on file with the Contra Costa County Recorder and County Surveyor here in Martinez document parcel boundaries and easements, not building interiors. An as-built survey is the instrument that documents the structure itself; we can combine it with boundary work when a project needs both.
