Red River Floodway Inlet Control Structure Trunnion Anchor Replacement - 2013

KGS Group and SNC Lavalin

Reliable operation of the gates at the Floodway Inlet Control Structure is critical to protecting Winnipeg during large floods. The gates have performed well for over 45 years, however, life extension measures were now required to ensure the gates continue to provide reliable protection. These measures include replacing the anchors that secure the gate trunnions (hinges) to the concrete. This projects challenges included: tight timelines, unprecedented drilling and tensioning methods; replacing and tensioning 44 anchors with a total load of 11 million pounds and precise 3D drilling and machining within confined spaces.
