3D Scanning in Mill Valley, CA

Mill Valley is built into redwood canyons on the flank of Mount Tamalpais, and almost every project here starts with the same problem: the site is too steep, too wooded, and too built-up to measure conventionally. Houses perch on cribbing and caissons above the street, driveways drop away at grades no rod person enjoys, and decades of retaining walls, stairs, and decks have accumulated on lots that were laid out on paper long before anyone walked them. A terrestrial scanner turns that into a tractable problem. From a handful of setups it records the ground surface, every wall face and stair, tree trunk locations, the neighboring structures, and the existing house as one registered cloud, and vegetation is filtered out in processing to leave a true bare-earth model instead of a canopy.

The infrastructure in and around Mill Valley is water-driven. Highway 101 crosses Richardson Bay on a causeway just east of town, the low ground at Tam Junction and Manzanita floods on king tides, and the creek network below Mount Tam runs through culverts, box structures, bridges, and channel walls that both the town and private owners have to maintain. Scanning those assets on a survey control network produces real structure geometry, invert and soffit relationships, channel cross sections, and clearance data, all on a recognized vertical datum, which is what any flood or hydraulic analysis needs to be credible. The same control lets a later scan measure whether a wall or an abutment has moved.

Downtown and the flats around Sycamore Park add the building work: older commercial buildings and shingled houses undergoing renovation, where measured plans, sections, and elevations come straight out of the cloud. Deliverables are E57 or RCP point clouds, DWG/DXF drawings, and Revit models. See our Mill Valley topographic surveys, as-built surveys, and infrastructure scanning.
