In 2012, Parks Canada personnel identified signs of slope movement on the southbound lane of the Cabot Trail near Corney Brook. Indications of slope failure included loss of material from the 60-m high cliff, a large pile of rubble at the base of the cliff, and a tension crack on the edge of the road. The Principals at HGC developed three conceptual designs and proceeded with the preferred option. They were responsible for developing the tender package and specification for construction of the retaining system which comprised a system of drilled soldier piles, concrete lagging, and high-capacity rock anchors to support a large unstable wedge of rock.
