Champlain Bridge Sector
Custom design for the pier cap reinforcement system
In July 2017, the Government asked JCCBI to conduct a risk analysis about the possibility of extending the Champlain Bridge’s service life by 12 to 24 months in case the delivery of the new Champlain Bridge was delayed.
One of the COWI Report’s recommendations was the design and installation of a reinforcement system to increase the bearing capacity of the pier caps, particularly the 39 pier caps considered most at risk.
These structural elements, which were designed and manufactured in Quebec in the Saguenay–Lac-Saint-Jean and Mauricie regions, are very impressive. Approximately 50 people were involved throughout all stages (design, manufacturing, delivery and installation), and the entire process from beginning to end took up to 10 weeks.
Since each pier cap is unique, there were many challenges during the tensioning and after the installation due to specific adjustments to satisfy the requirements of the plans and specifications.
Starting in August 2018, the 39 pier caps were reinforced without any hindrances to traffic, as the work was done primarily from the St. Lawrence River under the Champlain Bridge.
