For this project, SRI was responsible for
locating clear areas for the placement of 1200+ anchors. These
anchors would hold an electrical conduit rack system that will span
the entire length of the bridge. The installation of a leak
detection system throughout the bridges pontoons required us to
climb, ladders and equipment, in and out of every pontoon cell
for over 850 cores throughout the length of the bridge. SRI
utilized the latest in RADAR technology to locate the rebar mats on the underside of the bridge
and structurally important rods in the walls of the bridge.

SRI was able to provide the documentation for every location, an important element
in helping hasten the speed of the project. All locations needed to
be submitted to the general for verification to core.

With over 850
cores throughout the length of the bridge, radar, with its speed and
mobility, was an important key to the job.

SRI was also involved in
the repair and replacement of columns on a transported section of
the hood canal bridge. Rebar was damaged in the removing of the
existing column; thus they called us in to find them doweling
locations that were clear of all post-tension cables and large
reinforcing steel.

Our goal is to
provide areas for our customers to safely
core, through clear communication.
