Allnorth was engaged by Graham Infrastructure LP – Calgary (Graham) to complete a structural design for a semi-temporary concrete isolation wall and steel gate, both located in a water channel at the Bonnybrook Wastewater Treatment Plant in Calgary, AB.
The revamp of the semi-temporary steel wall aimed to serve a dual purpose: to hold back water on one side while simultaneously acting as formwork for a concrete wall on the opposite side. This complex design had to account for withstanding a water load of 0.8 metres as well as a concrete load of 4 metres in elevation.
Furthermore, Allnorth was approached to develop the structural design for a permanent, inversed T-shaped concrete retaining wall, alongside a concrete mud slab for high sulphate (HS) crack control in storm culverts. Within this scope, the structural engineering team designed two slabs. The first was a crack-controlled slab, positioned at the west wall, while the second took the form of a mud slab, positioned at the east wall.
Throughout the construction phase, Allnorth’s structural engineering team was available on-site to ensure the accurate execution of the design.
