As-Built Surveys in Moraga, CA
We provide laser-scanned as-built surveys throughout Moraga in Contra Costa County, documenting the town's 1960s and '70s ranch homes precisely enough that additions and remodels fit the existing structure the first time.
As-Built Surveys in Moraga: Local Conditions
Moraga's housing stock is dominated by ranch-style subdivisions built in the 1960s and '70s across ground that mixes Moraga Formation volcanics with the weaker sediments of the Orinda Formation — a combination that has made the town well known for landslide activity on developed slopes. For the single-story ranch houses that define these neighborhoods, the most common project we support is the addition: a new primary suite, a second story, an expanded kitchen wing. Additions are unforgiving of bad existing-conditions data, because new framing must land on real plate heights, real floor elevations, and real wall lines. A ranch house that has spent fifty years on slowly deforming ground rarely matches its tract drawings, and an addition designed from those drawings inherits every accumulated error.
Our approach is a single site visit with a Trimble terrestrial laser scanner. The scan captures the full envelope and interior — long low rooflines, eave and ridge heights, slab or crawl-space floor levels, every wall and opening — as millions of survey-grade points. From that point cloud we produce dimensioned floor plans, sections through the connection zone where new construction meets old, and exterior elevations, or a Revit model at LOD 200 or 300 when the architect is designing the addition in BIM. Because the scanner records true geometry, a family room whose floor has settled toward the downhill corner shows up exactly that way in the deliverables, and the engineer detailing the addition's foundation can see it before framing starts. On lots backing open-space boundaries at Moraga's semi-rural edges, pairing the as-built with a boundary and topographic survey puts structure, property line, and ground surface in one coordinate system for the Town's planning review.
Every project includes the registered point cloud in E57 or RCP format for later dimension checks with no return trip. As-builts are not recorded documents, but when associated boundary work finds or sets monuments, B&P Code §8771 requires a Corner Record or Record of Survey filed with the Contra Costa County Surveyor, and we take care of that filing.

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.
