3D Laser Scanning
Mobile scanning video
3D laser scanning provides clients with a wealth of data at a significant cost savings. Psomas is at the forefront of this new survey technology, providing fast 3D data collection with high accuracy and high resolution for applications ranging from roadways and rail corridors, utility corridors, waterways, ports, and airports, to as-built surveys, asset management, conceptual design, historical archiving and mechanical facilities.
Benefits of 3D Laser Scanning
Safety First: 3D laser scanners can be used in hazardous conditions, from the scanning of traffic lanes to hazmat sites, creating a safe environment for survey crews, contractors and the public.
Cost Savings: A vast amount of data can be acquired in a minimal amount of time and with less manpower. There is no interference with operations or construction activities.
Data-Rich File: Static 3D laser scanning produces a vast amount of accurate site detail. 360° horizontal by 270° vertical field of view allows for “over-coverage” of the site. The mobile scanner collects a full 360° view. The end product is a data-rich file for current and future needs.
Deliverables: Deliverables can range from raw point clouds and 2D plans to Digital Terrain Models and 3D as-built models for BIM projects. Psomas can provide final products in all major formats.

Mobile Scanning, Doyle Drive / Route 101
San Francisco, CA
The existing access road from San Francisco’s Golden Gate Bridge, Doyle Drive, is structurally and seismically unsafe and needs replacement.
Doyle Drive has been re-envisioned as the Presidio Parkway— a spectacular entrance from the iconic Golden Gate Bridge into the city of San Francisco. Caltrans turned to Psomas to help implement the use of mobile laser scanning for the survey work, which required the acquisition of design-grade survey data over 15 highly restricted lane miles.
Alameda County, CA
Caltrans brought Psomas on board to provide a solution to study the impacts of the road improvements on Niles Canyon, a difficult to access creek tributary flowing into San Francisco Bay. The result was a dynamic marriage of surveying technologies, including laser scanning with hydrographic and topographic surveying that produced a wealth of data.
