In-stock Atlantic Arch saves the day in BC washout

February 1, 2013

Tillicum(250)When heavy rains washed out an aging culvert cutting off a residential neighbourhood in Vernon, BC, The Ministry of Transportation and Infrastructure needed to find a solution quickly. An assortment of pre-engineered, in-stock Atlantic Arches in our nearby Armstrong yard made it possible for us to offer immediate delivery and on-site assistance.

Open-bottomed design prevents future flooding 

The failed 2 m round culvert was replaced with our 3.658 m open-bottomed Arch allowing for a much better hydraulic flow to help prevent future flooding. Atlantic Arch stocked sizes range from 1.2 m to 4.2 m spans. The structure was shipped in nested sections with 16 rings assembled on site and placed on the cast-in-place footings in less than a day. The contractor supplied the cast-in-place headwall and wingwalls on the upstream end.

Atlantic Arches are made from Dur•A•Span Structural Aluminum Plate, which the client had never used before. Once made aware that it was corrosion/abrasion-resistant and that it had been successfully used in over a thousand installations worldwide, they were convinced. In fact, they were so pleased that they decided to use it for another culvert project.
