Granville Bridge Seismic Upgrade

In 2009, Pacific Bolt worked on the Granville Bridge Seismic upgrade project. The project was designed to strengthen the concrete bridge girders in the event of an earthquake.


Pacific Bolt worked closely with the contractor, engineers, and owner to create a special coupler that would connected a M15 metric mechanical coupler to 20M Gr400 Rebar tie rod. These couplers were designed, tested and manufactured by Pacific Bolt and their supply partners. The coupler replaced the original design which required 3 different parts to achieve the same result.

By developing this coupler in our in-house CNC machine shop, we were able to supply a part that:
• Reduced the cost for the contractor and the owner
• Made installation of the tie rod quick and painless

The project was finished on time and on budget, which was extremely important as the project needed to be completed before the 2010 Winter Olympics.
