Rehabilitation of Sewer and Water Conduits in Montreal

Beyond traffic maintenance

Intervia was responsible for identifying and anticipating the impacts of the ongoing works and for continuously adapting traffic management and maintenance strategies. To do so, Intervia’s engineers had to fully understand the characteristics of the surrounding environment, analyze them, and establish correlations between these characteristics, the construction activities, and the needs of the local community in order to assess their impacts.

Once the impacts were identified, the information was shared with all relevant parties—including other work sites, boroughs, the Ministry of Transport, transit services, and affected stakeholders. In addition, meetings were organized with residents to explain the nature of the work and gather information about their specific needs.

Only then could Intervia’s engineers design temporary layouts that prioritized user safety, particularly for cyclists and pedestrians, propose scenarios that accounted for accessibility, traffic conditions, and public transit, and recommend adjustments to vehicle circulation patterns to ensure smoother traffic flow.

Methodology and expertise

To meet the complex requirements of this mandate, Intervia developed a rigorous methodology to coordinate and monitor many work sites simultaneously and to keep pace with their rapid execution schedules.

The daily challenges of adapting plans designed on paper to real-world conditions required both flexibility and discipline to ensure that all measures were implemented accurately at the right place and time.

The mandate also included a construction communication component. Intervia’s liaison officers accompanied residents, managed complaints, and participated in coordination meetings. Finally, Intervia ensured the presence of police officers to assist with traffic management.
