WEEKLY COORDINATION OF MUNICIPAL CONSTRUCTION WORK

City of Laval and Ministère des Transports du Québec

With a large number of active construction sites on the Island of Laval in 2008, the City of Laval and the MTQ had to be certain that the work would have the least possible impact on residents and highway users.

To this end, CIMA+ was asked to identify and schedule the work to be completed in 2008 on the local and arterial networks for the City of Laval and the Ministère des Transports. A weekly schedule and daily management were performed according to start-up dates and progress status of the various construction sites, in order to avoid conflicts such as road closures, and to reduce negative impact on users.

REDEVELOPMENT OF SAINT-LAURENT BOULEVARD

Borough of Plateau-Mont-Royal

Within the context of the highway reconstruction program for the City of Montreal, the assignment given to CIMA+ consisted of monitoring and coordinating all of the rehabilitation work on Saint-Laurent Blvd, including:

• replacement of water supply and drainage pipe lines
• rehabilitation of underground networks
• sidewalk reconstruction and widening
• reconstruction of lighting systems and traffic lights
• reconstruction of foundations and pavements

An important aspect of the mandate granted to CIMA+ was to ensure maintenance of automobile, cyclist and pedestrian traffic, and permanent accessibility to commercial and residential establishments.

In order to accomplish this, we ensured the coordination of the work in a particularly complex context since four different contractors were involved in the underground work and four others in the surface work. It was imperative that all of these teams worked together to ensure the success of the project within the given timeline, keeping the impact on neighbourhood residents to a minimum.

We also established an effective communications system aimed at keeping businesses and residents informed of the progress of the work and addressing their concerns.

PROJECT SUPERVISION, COORDINATION OF TRAFFIC, AND ROADWAY RECONSTRUCTION

Ministère des Transports du Québec

CIMA+‘s assignment consisted mainly of providing coordination of the work and traffic management in an important corridor of the Montreal region, with circulation of over 150,000 vehicles per day.

Among other things, we developed the work phase design and the plans for detour signage, or detour routing. Our team was in communication with the various stakeholders on a daily basis, checking for potential signage conflicts and validating requests for lane closures.

The main projects involved in this area focused on:

• reconstruction of the bridge on Autoroute 25 (Île Charron) above the St. Lawrence Seaway
• maintenance work in the Louis-H.-Lafontaine Tunnel
• reconstruction of the Hochelaga Bridge and the Tellier Street Bridge on the Island of Montreal
• reconstruction of roadways at the southern approach to the bridge in the Autoroute 20 corridor

TRAFFIC management AND COORDINATION OF LANE CLOSURES

Ministère des Transports, direction de l'île-de-Montreal
(The department responsible for the Island of Montreal at the MTQ)

The road network owned by the MTQ on the Island of Montreal is the most heavily used in the Province of Quebec and also is one that required the most frequent interventions in terms of ongoing maintenance.

CIMA+ was asked to ensure traffic management throughout this area and more specifically: 

• coordinate and minimize the impacts of the simultaneous activities of several construction sites in operation during the same period
• plan, integrate and analyze various possible mitigation and traffic management measures
• inform all partners regarding short and medium term lane closures on the highway network
• identify interactions between construction sites and special events within the region

In addition to these activities, CIMA+ designed detour routes, signage plans and plans for phasing the work, completed site surveys and counts, and provided technical assistance to site supervisors (start-up, phase changes, site shut down, configuration, signage and road marking).

Successful completion of this project illustrates the breadth of expertise CIMA+ has in this field.

PRELIMINARY STUDY FOR THE RECONSTRUCTION OF THE TURCOT COMPLEX

Ministère des Transports du Québec

The Turcot Interchange represents one of the busiest areas on the Island of Montreal in terms of traffic volumes. Managing this traffic during construction was the major element to take into account in order to complete this project.

CIMA+ was asked to study the itinerary of detour routes to permit long-term closures of roadway connections during the various phases of the work. These detour routes were studied in terms of observable traffic limitations in the area, including trucking restrictions and clearance beneath the many surrounding structures.

RECONSTRUCTION OF AUTOROUTE 720

Ministère des Transports du Québec

This project involved the reconstruction of the freeway structure and the replacement of expansion joints on Autoroute 720 in both directions, between the Turcot Interchange and the Ville-Marie Tunnel.

This segment is the main freeway access to downtown Montreal. Traffic at this location is, therefore, very dense. The work required staging to allow the contractor sufficient space to perform his work, while keeping the impact on users to an absolute minimum.

CIMA+ was able to guarantee traffic management throughout the performance of this project.
