3D Scanning in Auburn, CA

Auburn is the Placer County seat, and its oldest core is a National Register district. The Old Auburn Historic District, bounded by Maple, Commercial, Court, Washington, Spring, and Sacramento Streets, holds buildings put up mostly after the fire of 1855, among them Lawyers Row and the Chinese Joss House, with the historic courthouse above them still housing the Superior Court and the Placer County Museum. Buildings like these sit on sloping ground, carry thick stone and brick walls that lean and bow, and have been altered for well over a century. A scan records all of it, facades, interiors, stairs, and grade along the street, so the architect and structural engineer start from measured geometry rather than a sketch.

The canyon brings a second kind of work. The Foresthill Bridge, a 2,428-foot steel span opened in 1973 and the highest bridge by deck height in California at 730 feet above the North Fork American River, was built for a reservoir that never came and went through a seismic retrofit from 2011 to 2015. Nearby, the 1912 Mountain Quarries Bridge, a concrete arch railroad bridge now on the National Register, once linked a limestone quarry to the Southern Pacific mainline in Auburn. Structures, retaining walls, and slopes on terrain like this are where a scanner earns its place: long sight lines from the rim or the deck capture surfaces a crew could not safely walk, and targets tied to control make a later epoch directly comparable. Closer to town, the city-owned airport includes an 80-acre industrial park of light manufacturing buildings, where equipment installs and additions need clear heights, column grids, and slab deviation maps first.

We are a licensed California surveyor based in the foothills ourselves, not a national scanning firm dispatching from out of area. Control is GNSS primary and total station secondary, held to 0.01 US survey feet relative to project control; scans are Trimble X9, check shots Trimble S3, processing in Trimble Business Center. You receive registered, cleaned point clouds (E57, LAS, or RCP), scan-to-CAD plans, sections, and elevations.
