Morrison Hershfield is involved in two major projects that are part of the repairs to Toronto’s Gardiner Expressway in the downtown and western portions. The company is consultant for the replacement of the deck on the elevated portion from the Canadian National Exhibition Grounds to Grand Magazine Street near Fort York and is also rehabilitating three bridges in the at-grade section of the expressway farther west between the Humber River and Park Lawn. AECOM is replacing the expressway’s median in the at-grade section between Dufferin and Ellis.

The Consortium Perron, Hudon, Bélanger and Consultants SM have been awarded a contract to do 3D terrain modeling and land surveying services for the new bridge over the St. Lawrence River in Montreal. The $290,300 contract includes aerial photography, 3D laser scanning surveys and processing of the data to develop numeric models and existing infrastructure for the project area. The new bridge is intended to replace the existing Champlain Bridge.

AECOM is consultant for the rehabilitation of the historic Poonamalie Dam on the Rideau Canal in Smiths Falls, Ontario. Parks Canada is investing $4.3 million to rehabilitate the existing earth dam and reconstruct a waste weir to improve the dam’s stability and visitor safety. The Poonamalie Dam was constructed in 1830 and controls water from the Big Rideau and Lower Rideau Lakes. Located in a 2.5-km excavated channel that bypasses the rapids and shallows of the river, the lock is manually operated and has a lift of 1.6 metres.
