3D Scanning in Fremont, CA

Fremont's industrial south end is dominated by one building. The plant now known as the Tesla Fremont Factory opened as GM's Fremont Assembly in 1962, ran as NUMMI from 1984 to 2009, and passed to Tesla in October 2010. Its main building covers about 5.5 million square feet, and Tesla is the city's largest employer. Around it, the Warm Springs/South Fremont BART station opened in March 2017, and the Warm Springs Innovation District has drawn technology headquarters including Lam Research. Production and equipment buildings are where scanning saves the most field time: line changes, mezzanines, equipment pads, overhead conveyors and services, and process piping all have to fit inside existing structure. A scan captures the whole volume in one pass, and we deliver plans, sections, 3D linework, and slab deviation and levelness maps for the facility engineers.

The north and east sides of the city are older than they look. Fremont incorporated in 1956 when Irvington, Centerville, Mission San José, Niles, and Warm Springs joined together. Mission San José was founded in June 1797, and in October 1868 an earthquake on the Hayward Fault, which runs through the mission grounds, shattered the walls of its church; the reconstructed church was rededicated in 1985, with the surviving portion of the original mission wing kept as a museum. Niles was the earliest home of California's film industry from 1912 to 1915. Buildings near an active fault are often in line for seismic retrofit, and a control-tied scan gives the structural engineer measured geometry to design from and a baseline that a later scan can be compared against. The same approach works in neighboring Hayward.

Contour Survey is based in Lotus, El Dorado County, and works across the Bay Area. Control is primary GNSS and secondary Trimble S3 total station, held to 0.01 US survey feet relative to project control, with every Trimble X9 setup tied in and processing in Trimble Business Center. For new buildings we verify anchor bolts and structural steel to 1/8 inch from the scan, with total station check shots on any bolt group near tolerance. You receive a registered, cleaned cloud (E57, LAS, or RCP), scan-to-CAD plans, sections, elevations, and coded points, with a report stating control basis, units, and accuracy.
