As-Built Surveys in Santa Rosa, CA

We deliver laser-scanned as-built surveys throughout Santa Rosa, Sonoma County, producing measured floor plans, sections, elevations, and BIM-ready models of buildings as they actually stand today.

As-Built Surveys in Santa Rosa: Local Conditions

Santa Rosa is the largest city in the North Bay and its building stock reflects that range. Railroad Square and the surrounding downtown blocks hold early stone and brick commercial buildings under continuous renovation and seismic upgrade, where the original drawings, if they exist at all, describe a building that has been altered a dozen times. The hospital, campus, and civic buildings around the city need existing-conditions documentation before every expansion and infrastructure project. Wine Country production facilities and hospitality buildings in the surrounding county carry tanks, mezzanines, and process equipment that a two-dimensional as-built simply cannot describe. And in the neighborhoods rebuilt after 2017, surviving structures adjacent to new construction have to be documented accurately so the new work fits against them.

Hand measuring a building of any complexity is a slow way to acquire an incomplete dataset. Our Trimble terrestrial laser scanner records millions of points per setup, registered into one coordinate system, and captures what a tape cannot: floors that are out of level, walls out of plumb, ceiling heights that change room to room, structural members behind exposed framing, and the real clearances around equipment. For a structural engineer designing a retrofit, that geometry is the analysis input. For an architect, it is the difference between a set that fits and a set that gets field-adjusted. We can also run deviation analysis against a design model to show where the built condition departs from the drawing.

Deliverables include the registered point cloud in E57 or RCP, scan-to-CAD floor plans, reflected ceiling plans, sections and exterior elevations in DWG/DXF, and Revit or other BIM-ready models at your specified level of development. Because the whole building stays in the cloud, later questions get answered from the data rather than from another site visit. See Santa Rosa 3D scanning for the capture side, and our comparison of scan-to-BIM and traditional as-builts.

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.

As-Built Surveys in Santa Rosa: FAQ

Survey-grade, and more importantly, uniformly so. A hand-measured plan is accurate where someone measured and interpolated everywhere else, and errors accumulate around the loop. A registered scan holds tolerance across the whole building, so a dimension between two points 200 feet apart on opposite sides of the structure is as reliable as one across a single room.

Usually yes. Setups take a few minutes each, so we work around production schedules, off hours, or in phases. We do need line of sight, so we plan the setup pattern with your facilities team to reach what matters. Anything visible from a setup is captured, which means the mechanical, electrical, and structural context comes along with the architecture at no extra field time.

It is generally cheaper, not more expensive, once the building is more than a few rooms. Field time drops sharply and the plans get cut from the cloud in the office. You also get the sections, elevations, and ceiling data as a byproduct, so when the scope grows mid-project, as it usually does, the data is already there.
