F.A.Q.

Filter the questions

  • What are the construction hours ?

    Work usually takes place from Monday to Friday between 7 a.m. (with teams arriving on-site around 6:30 a.m.) and 7 p.m., sometimes extending to the weekend, at the same hours. The daytime noise threshold is 75 decibels (including saturday and sunday).

    Please note that we may be forced to work evenings and nights, with greater restrictions on noise levels of 5 decibels above ambient noise (without construction). Work at these later hours is generally less noisy.

    Should construction begin to have a major impact on daytime traffic, we may choose, by way of exception, to work evenings and nights, even though the work may be loud.  Exceptionally, construction activities that exceed the nocturnal noise threshold despite the mitigation measures in place require an exemption from Infrastructure Canada with collaboration from the municipalities. 

    Signature on the Saint-Laurent is committed to respecting the noise levels agreed upon in its partnership agreement with the Government of Canada and, as such, will use mitigation measures whenever it becomes necessary. Please see the “Citizens’ forum” at the newchamplain.ca Web site to see our sound level checks.

    Our Environment team is on hand monitoring the site to make sure environmental requirements are met.

    We are aware that work on this major construction site can inconvenience people who live nearby.

  • I live nearby May Street. How will you manage air quality during the project?

    An air quality monitoring program will be developed and implemented before the start of work in the May Street area. Mitigation measures are planned to limit the impacts on air quality:

     

    • -Reduce speeds on the worksite in unpaved areas;
    • -Moisten traffic lanes and materials, as required, to limit the amount of dust rising;
    • -Maintain trucks in good operating to limit emissions.

     

    Equipment for continuous air quality measurement will be installed in the sensitive areas outlined in the environmental assessment. Each time an excess level is detected, an alert will notify the Environment team and corrective measures will be implemented to eliminate the source of dust production.

     

    The Infrastructure Canada team will also monitor air quality throughout the construction period. Air quality sampling results will be available to the public during execution of the project.

     

    Finally, air quality—as with all the impacts caused by the construction site—will continue to be discussed during meetings of the Comité d’intégration du nouveau pont et de ses accès (CINPA), a committee aimed at ensuring good neighbourly relations.

  • How will May Street be commemorated?

    Verdun borough gathered some suggestions from citizens. Signature on the Saint Lawrence will take them into consideration in its urban integration plan for this sector.

  • Why does May Street have to be relocated?

    The widening of Highway 15 is necessary to ensure transportation safety and corridor efficiency. This component of the project presents a significant challenge because it is located in a high-density urban environment. Various options were, therefore, assessed by Infrastructure Canada and its consultants.

     

    The new configuration was devised to optimize the current space while dealing effectively with the following set of constraints: the presence of a CN railway line; a Hydro-Québec high-voltage line; a retaining wall topped by a noise barrier; the St. Pierre collector, and; access to snow dumps. Based on these constraints, Highway 15 must be broadened mainly toward the south, that is towards May Street.

     

    The houses on May Street could not be kept for obvious safety and environmental impact reasons (air quality and noise pollution) due to the proximity of the highway.

  • When will the houses on May Street be demolished?

    Before the demolition of residences start, there will be removal of materials containing asbestos in accordance with CSST requirements Houses on May Street located close to Wellington Street will be the first to have asbestos removed and to be demolished. The contractor will begin demolition of the houses as soon as the asbestos has been removed. Asbestos removal and demolition will therefore take place simultaneously along May Street, up to the intersection with Jacques Lauzon Street. This work will take place during daytime hours. We estimate that it will be complete by the end of December 2015.

  • How will you measure air quality on the A15 works?

    Signature on the Saint Lawrence will use air quality monitoring stations that will be located in strategic areas taking into account dominant winds, sensitive zones and the location of the worksites. These air quality monitoring stations will measure the total particles and fine particles in the air. The results will be published on the website.

  • What is the role of the Verdun and Sud-Ouest boroughs in the project?

    The boroughs are major partners in this project. The City of Montreal and the Verdun and Sud-Ouest boroughs were first joined in talks by Infrastructure Canada so that technical orientations with respect to infrastructure and technical criteria for the call for proposals could be specified. Signature on the Saint Lawrence is working closely with the boroughs to plan construction and communications activities with citizens.

  • Will you be working during the evening and night shifts on the A15 related works?

    The majority of the work will be done during the day shift, between 7 AM and 5 PM. However, to minimize road closures, there will be occasions when evening and night shifts are preferred.

  • Will the work (on the A15) generate vibrations?

    A vibration assessment plan has been implemented for the entire new Champlain Bridge Corridor Project. Vibrations may be felt during the demolition work on May Street, but will not achieve levels that would potentially have an impact on neighbouring residences.

  • What is your approach to manage noise levels?

    As a result of the construction activities that will be taking place, some sensitive zones have been identified in Verdun and Le Sud-Ouest. If we anticipate exceeding the noise limits, mitigation measures are put in place such as temporary acoustic screens.

     

    The Environment Team tracks the work to ensure the criteria are respected.

  • Will anti-noise barriers be put up between Highway 15 and De la Poudrière/May streets while work is underway?

    Temporary acoustic screens will be installed before residences are demolished to reduce noise levels. This work will take place during daytime hours only. During this period, the noise threshold cannot exceed 75 dBA.

  • Will there be a permanent anti-noise barrier between Highway 15 and the De la Poudrière and May/Rushbrooke/Jacques-Lauzon area?

    Yes, a permanent anti-noise barrier will be built. The exact parameters of the wall are still in the design phase. Talks will be held with residents through the good neighbourly relations committee, as well as with Verdun Borough.
