Rehabilitation of Sewer and Water Conduits in Montreal

More than just maintaining traffic

Intervia had to identify and anticipate the impacts of the ongoing construction sites and continuously adapt traffic management and maintenance concepts. To this end, Intervia's engineers had to know the characteristics of the intervention environment, analyze them, and establish the correlation between these characteristics, the worksite and neighbourhood activities in order to deduce the impacts.

Once the impacts were identified, the information was disseminated to all other construction sites, boroughs, the Ministry of Transport, transportation service providers, and all affected parties. In addition, meetings were organized with affected residents to explain the nature of the work and collect information concerning their needs.

Only then were Intervia's engineers able to design temporary infrastructure that took into account user safety, including cyclists and pedestrians, propose scenarios that integrated accessibility, traffic conditions and public transit, and recommend changes to vehicular traffic to promote greater fluidity.

Methodology and know-how

To address all the constraints of such a mandate, Intervia developed a rigorous methodology to coordinate and monitor many sites simultaneously and thus keep up with their rapid pace.

The day-to-day challenges of changing the scenario at the design stage and its implementation in the field required flexibility and rigour to ensure that all measures were implemented at the right place and time.

The mandate also included a site communications component. Intervia's liaison officers accompanied local residents, handled complaints, and participated in coordination meetings. Finally, Intervia ensured that it obtained the services of police officers to assist with traffic management.
