3D Scanning in Crockett, CA

Crockett sits at the foot of the Carquinez Bridge, where Interstate 80 crosses the strait on two separate structures: the Alfred Zampa Memorial Bridge, a suspension span opened in 2003 carrying westbound traffic, and the 1958 steel truss carrying eastbound, with approach spans and interchange ramps landing on the Crockett side. Below the town the Union Pacific line runs along the strait, and on the waterfront the C&H Sugar refinery is both a working plant and one of the more remarkable pieces of early-1900s industrial architecture in the Bay Area. Above it all, the company-town streets terrace up the bluff behind generations of retaining walls. Bridge and structural engineers, industrial and process engineers, preservation architects, and the county and district staff who maintain those hillside streets are the people who need scan data here.

For structures we work control-tied. Monuments are set and observed with GNSS and total station, every Trimble scan position is registered to that network, and residuals are reported, so the cloud is survey-grade coordinates on a stated datum. That supports vertical clearance surveys, structural as-builts of bents, girders, bearings, and connections, and repeat epochs differenced against a baseline where deflection or settlement is in question. The scanner also solves an access problem that defines this place: geometry high above a roadway, out over water, or on a bluff face is captured from safe ground positions at millions of points per setup, without rope access and without a second lane closure to collect the dimension nobody anticipated. For historic industrial fabric, the same cloud yields facade elevations and structural geometry accurate enough for rehabilitation design.

Deliverables are the registered cloud in E57 or RCP, DWG or DXF scan-to-CAD, Revit models, and clearance and surface reports. See our infrastructure scanning for structures, Crockett as-built surveys for buildings, and Crockett topographic surveys for terrain and walls.
