As-Built Surveys in Antioch, CA

We provide as-built surveys in Antioch, one of Contra Costa County's oldest cities, laser scanning the historic riverfront downtown's storefront buildings so renovation teams can design against true existing geometry.

As-Built Surveys in Antioch: Local Conditions

Antioch's historic downtown faces the San Joaquin River, and its older commercial blocks hold the kind of storefront buildings that reward renovation: masonry and timber structures with high ceilings, mezzanines, and street frontages built long before modern drawing archives. For the architects and developers now reinvesting in this riverfront core — restaurants, mixed-use conversions, facade restorations — the first deliverable any project needs is an accurate record of what exists. Our as-built surveys provide it. With a Trimble terrestrial laser scanner we capture a storefront building inside and out in one visit, including the facade detail that matters for restoration work, and deliver DWG floor plans, sections, and elevations, Revit models at LOD 200 or 300, and the full point cloud in E57 or RCP.

Older commercial buildings hide their complications well. Party walls are rarely plumb, floor and mezzanine levels drift, storefront openings have been resized repeatedly, and roof structures are a patchwork of eras. The scan records all of it as measured fact, which is what a retrofit engineer needs before touching an older masonry building and what an architect needs before promising a tenant a floor plate will fit. Because the point cloud is complete, later questions — clear heights under a mezzanine, the exact rhythm of a facade — are answered from data rather than repeat site visits. Antioch's waterfront margin along the Delta includes areas mapped under the state Seismic Hazards Mapping Act, which can bring geotechnical review into substantial renovations near the river; honest existing-conditions documentation keeps those submittals credible. Recorded maps for downtown parcels are held by the Contra Costa County Recorder and County Surveyor in Martinez, and when a conversion project needs lender-grade due diligence we can pair the as-built with an ALTA/NSPS Land Title Survey to the 2021 standards.

From a single scan visit, every consultant on the team works from the same true geometry — the fastest way to move a downtown Antioch renovation from idea to permit.

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 Antioch: FAQ

Usually, yes. Scanning is non-contact and quick per setup, so we can work around business hours or move through an occupied space with minimal disruption, often completing a typical storefront building in a single visit. We coordinate timing with the owner or tenant so the survey never becomes the project's bottleneck.
For a conversion, we typically recommend a Revit model at LOD 200 or 300 plus the E57 point cloud, so the architect models directly against real geometry and every consultant can verify dimensions independently. If lenders or title are involved, an ALTA/NSPS 2021 survey of the parcel is a natural companion, with records researched through the county offices in Martinez.
Potentially. Parts of Antioch's Delta shoreline margin fall within zones mapped under the Seismic Hazards Mapping Act, which can trigger additional geotechnical review for significant work. That review is separate from the as-built survey, but accurate scan-based drawings of the existing structure make the whole submittal package stronger.
