When MTQ needed to install a replacement stream-crossing solution in a remote area on the Gaspé Peninsula, a twin Bolt-A-Plate Round solution was selected. The new 3.36 m diameter structures replaced one aging 2.75 m culvert running under the rail bed near Chandler, QC.
Given the deep-cover requirements of this site, we value engineered the structures for maximum strength at reduced cost. These aspects added some complexity to the plate-assembly task for the contractor, Hamel Construction, but our on-site representative was able to assist with some support from our regional engineer.
The structures were installed at two different elevations. One was installed at a lower upstream elevation as a fish-passage solution with custom baffle inserts. A cast-in-place concrete wall provided extra support and washout resilience for both culverts at the upstream end.
In the end, all parties were pleased with the project outcome and another Bolt-A-Plate order came in this year with the same contractor and the same team.
