Seattle Light Rail


CUSTOMER:

L.K. Comstock | WSDOT

LOCATION:

Link Light Rail (Seattle, WA)

CHALLENGE:

Locate embedded steel and conduits in a Seattle Light Rail tunnel for retrofitting a three-foot steel plate to hold an extended arm providing energy to the transit buses and trains.

SOLUTION:

With state-of-the art ground-penetrating radar, safety equipment and lifts, SRI technicians scanned the length of several support columns to determine safe locations to penetrate the concrete and add necessary reinforcements.

OUTCOME:

Structural Radar Imaging successfully located rebar and conduit inside eight columns, and identified safe locations in walls and floors for more than 100 anchors and more than 30 cores. As a result, rail crews were able to anchor critical steel I-beams to the concrete, for improved safety and performance.
