SCANNING & SURVEYING

SCANNING

Laser scanning is a popular land surveying method that can accurately measure and collect data from objects, surfaces, buildings, and landscapes. Laser scanners collect information in the form of point cloud data, which consists of millions of 3D coordinates. When the point clouds from laser scans are processed, they form a digital representation of the scanned surfaces, demonstrating the dimensions and spatial relationships of topographic features and structures. 

SR 99 TUNNEL SCAN

SCE was responsible for performing a laser scan of the Seattle SR 99 tunnel to map the levels of displacement across its surface. A three-dimensional image was constructed of the tunnel’s interior, providing high-precision data on the topography of the tunnel’s lining. The data was used to assess the correctness of the tunnel’s center line, as well as evaluate the form of the lining itself.

ROOF SCANS

SCE completed 3D laser roof scans for solar array installations at two California locations. Using a combination of a Faro Scene and Leica BLK360, we produced 3D models of the rooftops to be used in solar array layouts to ensure minimal conflict between existing roof features and solar installation. SCE has 7 large rooftops to date including the 300,000 sf Kroger Bakery in La Habra and multiple buildings at California State University Dominguez Hill.

ALASKA WAY VIADUCT DEMOLITION

SCE completed the pre- and post- demolition building inspections for the structures that fell within the limits for demolition activities along the Alaska Way Viaduct.  We also performed a scan survey of the viaduct before and after to document project completion and demolished structural elements.
