Lighting system installation

Our team was entrusted with the installation of an LED lighting system on the Jacques-Cartier bridge in Montreal.

We subcontracted 100% of the work and provided the following services:

  • Procurement
  • Developing construction methods and logistics
  • Planning design and construction activities
  • Applying BIM (Building Information Modelling) technology to coordinate production with the existing structure
  • Monitoring electrical and structural installations for quality control
  • Initiating FAT (factory) and SAT (site) testing of all electrical equipment.

The project consisted of installing an interactive lighting concept of 2,800 lights and projectors, activated in real time according to the seasons and the City of Montreal's energy. Data from traffic, weather and social networks were connected to the system, so the bridge is, in effect, animated by the city's activities.

Between 60 and 80 workers installed the system at heights ranging from 40 ft to 150 ft above the traffic and 200 ft to 300 ft above the river.

Despite a tight schedule and multiple challenges, the $22.9 million project, which started in August 2016, was completed in April 2017.

Our challenges

A tight schedule

To meet the tight schedule, we worked 24 hours a day, 7 days a week, half of that time in the winter. We also worked closely with the design team.

Difficult-to-access site

To increase access to the site, we used certain methods and equipment, including elevators and scaffolding suspended from the bridge.

Managing traffic

Throughout the work, we successfully managed traffic and coordinated road closures.
