Some projects undertaken in Quebec
Champlain Bridge, Montréal
The Champlain Bridge is the most travelled bridge in Canada. Since its opening in 1962 the amount of traffic has been continuously increasing. We see a current yearly circulation on the Champlain Bridge of 57.1 million vehicles. It is subject to extreme operating conditions (heavy traffic, high thermal variations, the effects of freezing/thawing, effects of salting during the winter) Mr. Bernard Hodac, CEO of the OSMOS Group, states it represents a challenge similar to the monitoring of the Eiffel Tower.
Henri-Bourassa Overpass, City of Montréal
Built in 1938 and without any documentation, the bridge, as supported by traditional evaluation methods of the time (visual and physico-chemical), had been categorized as not being able to support anything other than passenger vehicles (maximum weight 5 tons). With the expertise of OSMOS Canada an evaluation protocol was established which allowed the structural capacity of the bridge to be increased to 47 tons. As well, a continual monitoring surveillance through OSMOS Canada, eliminates the necessity of personnel currently regulating bridge traffic. There were six police officers working both day and night shifts.
Stukely-South Overpass, Quebec Ministry of Transport
A thick concrete slab bridge at a 54° bias with many cracks, are just some of the complications that make traditional evaluation methods very difficult. According to the elected officials, these factors alone were enough to close the bridge. However, the objective of keeping it open to serve the whole community was a necessity. OSMOS technology intervention, coupled with the bridge engineering experience from Teknika HBA allowed to eliminate the uncertainty of the bridge’s structural integrity and allowed for its reopening in complete safety until the rehabilitation works could be planned and completed.
Coaticook bridge, Quebec Ministry of Transport
Crossing the Coaticook River, this steel Pony-Warren type bridge was constructed in 1922. It is an access impossible to circumvent for the downtown area of Coaticook. Six optical strands, a signal and treatment system (SPCU) and two data acquisition units (DAU) assure a continual secure surveillance. With over 200 vehicles per day passing over the bridge, in particular heavy vehicles of several tons, there is no margin for error of the bridge’s integrity and specifically after its heavy usage over the past years. OSMOS expertise assures the bridge’s use for many years to come in complete safety and permits the client’s ability to target the necessary works over time.
Quartier International, William Collector Sewer, City of Montreal
The old William Collector Sewer is a structure classified as an historic monument. The city of Montreal wanted to set up a 1.1 meter fill above the collector, within the framework of refitting Youville Square in Old Montreal. Using OSMOS technology, the works’ integrity can be identified and its weak points noted, permitting the advancements of further works worth several million dollars.
