3D Scanning in El Sobrante, CA

El Sobrante sits in the valley of San Pablo Creek, and the creek is why the water infrastructure of the East Bay runs past its front door. San Pablo Dam Road climbs east from the community toward San Pablo Dam and Reservoir, part of the East Bay Municipal Utility District system, with district watershed land and treatment and transmission facilities in the hills above. The road itself is a county arterial carrying retaining walls, culverts, and creek crossings along its length, and El Sobrante is unincorporated, so that infrastructure is Contra Costa County's to maintain. The result is a scan market split between agency and utility engineers working on structures and a steady residential and small-commercial demand across the valley's larger, semi-rural lots.

High-accuracy scanning on water and roadway structures follows a specific method. We observe a control network with GNSS and total station, register every Trimble scan position to it, and report residuals, so the point cloud is survey-grade coordinates rather than a self-referencing model. From it come as-built geometry of concrete structures and appurtenances, wall face and batter profiles, culvert and conduit interiors where access allows, tank and vessel shell checks, and repeat epochs differenced against a baseline to reveal settlement or deflection across an entire surface instead of at a few points. The instrument reaches geometry that would otherwise require rope access or a lift, and because millions of points come off each setup, the dataset answers questions nobody thought to ask in the field.

Standard deliverables are the registered cloud in E57 or RCP, DWG or DXF scan-to-CAD, Revit models where a building is involved, and profile and surface reports.
