As-Built Surveys in Napa, CA

We deliver laser-scanned as-built surveys in Napa, Napa County, turning existing buildings into registered point clouds, scan-to-CAD drawings, and Revit-ready models that architects and structural engineers can design on directly.

As-Built Surveys in Napa: Local Conditions

Downtown Napa's older commercial core is a scanning problem by construction type. Brick and stone buildings from the late nineteenth and early twentieth centuries have thick, irregular walls, floors that have settled unevenly, and drawings that either never existed or stopped matching the building several remodels ago. The 2014 South Napa earthquake on the West Napa fault made that documentation gap expensive: the magnitude-6.0 event concentrated its damage on exactly this masonry stock, and the retrofit, repair, and reuse work it set in motion still needs measured geometry rather than assumed geometry. A structural engineer sizing an anchor pattern into a three-wythe brick wall wants to know where that wall actually stands, out of plumb and all.

Hospitality is the other steady source of as-built work here. Hotels, inns, restaurants, and event space downtown and along the river get repositioned on short schedules, frequently inside buildings that have already been converted once or twice, so whatever drawings survive describe a layout that no longer exists. Tenant improvements and mechanical upgrades hit the same wall: a designer routing new ductwork above a finished ceiling needs the real structure and the real clearance, not a dimension inferred from an old floor plan. We capture interiors, exteriors, roofs, and above-ceiling space in one visit, so the deliverable carries framing, existing systems, and finish surfaces together. Wine caves and winery production buildings have their own field considerations, covered on our Napa scanning page.

One mobilization captures the site in millions of survey-grade points. From that cloud we deliver 2D floor plans, reflected ceiling plans, elevations, sections, and a Revit or BIM-ready model at the level of development your team needs, along with the registered E57 or RCP cloud itself. Anything missed is extracted from the data rather than measured on a return visit. Where the same building is headed for a subdivision of ownership, the scan also feeds the unit plans on our Napa condominium conversion work, and our Napa laser scanning page covers the field process in more detail.

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 Napa: FAQ

Field time is usually a day or less for a typical two- or three-story main-street building, including interior, exterior, and roof where accessible. Registration and drafting take longer than the field work, and the schedule depends on the deliverable: a point cloud and 2D plans turn faster than a fully modeled Revit file.

Yes. The scanner works from tripod setups and needs only brief clear sight lines, so we can work around guests and service rather than closing a room down. We usually plan the visit for the quietest window and accept that people will appear in the data, since transient objects are removed in processing. Guest rooms are scheduled around housekeeping.

Registered point clouds from our Trimble scanner hold survey-grade accuracy across a building, typically a few millimeters at the individual scan level and a small fraction of an inch across a registered project. The practical result is that dimensions taken from the drawings match the building in the field, which is the whole point when you are fitting new structure or equipment into old walls.
