AIL designed and supplied seven Bolt-A-Plate watercourse crossings for construction/access roads at the Weavers Mountain Wind Energy Project in Nova Scotia.
Before the tender call, the AIL team worked with the consultant, DesignPoint, to review Department of Fisheries and Oceans requirements and assess suitable Bolt-A-Plate geometries. Of the 11 crossings originally planned, seven were ultimately constructed.
The open-bottom, fish-friendly arch spans ranged from 1.52 m to 6.5 m, and the two largest structures incorporated AIL’s MSE Wire Walls. A value engineered headwall and wingwall solution reduced the length of these deep-valley, high-cover crossings, lowering overall costs.
AIL’s in-house engineering team designs a range of precast footings
AIL’s in-house engineering team also designed several precast concrete footing configurations that met CHBDC requirements for a minimum 2 m embedment on structures without inverts.
About the Weavers Mountain Wind Energy Project
Straddling the Pictou/Antigonish county line south of Highway 104, Weavers Mountain Wind Energy Project is a design-build initiative by the Mi’kma’ki-Municipal Limited Partnership. When completed, it will have 16 large turbines with a total capacity of 94.4 MW, or enough power for up to 33,000 homes.
