3D Scanning in Rocklin, CA

Rocklin is named for its rock. The Central Pacific gave the town its name in 1864 for the granite quarry at the end of its new track, and built a roundhouse there in 1867 before moving the facility to Roseville in 1908. According to the Rocklin Historical Society, Rocklin quarries shipped granite for the California State Capitol and San Francisco's Palace Hotel, and by 1895 at least 12 were operating. Local historians count 62 quarry pits opened and abandoned over the years. Many are now filled with water or debris, one lies under the westbound lanes of Interstate 80, and the largest 19th-century pit, near Granite Street and Rocklin Road, now sits under a building and a parking lot. The Big Gun Quarry near Pacific Street and Rocklin Road was the last to work and closed in 2005; it is now Quarry Park. Old cut faces, stone foundations, and sites built over filled ground are all places where a scan records surfaces that ordinary shots would only sample.

The modern city is much bigger than the quarry town. Rocklin incorporated in 1893 and counted 71,601 residents in 2020. Interstate 80 and Highway 65 meet here, and the Capitol Corridor stops at the Rocklin station. Education is a large part of the building stock: the main campus of Sierra College, whose district covers more than 3,200 square miles, William Jessup University, and the Rocklin Unified schools, with 13 elementary, two middle, and two high schools. Campus modernization means existing-conditions plans of buildings that have been added to for decades, scanned on breaks or after hours. Commercial and light industrial buildings along the freeways bring construction verification: anchor bolts and steel checked to 1/8 inch from the scan, with total station check shots near tolerance, and slab deviation and levelness maps before and after the pour.

Our office is in the El Dorado County foothills, and we schedule South Placer work together with jobs in Roseville and Auburn. Control is GNSS primary and Trimble S3 secondary, held to 0.01 US survey feet relative to project control; scans are Trimble X9, processed in Trimble Business Center. Deliverables are a registered, cleaned point cloud (E57, LAS, or RCP), scan-to-CAD plans, sections, elevations, 3D linework, coded points, and a report stating the control basis and accuracy achieved.
