New Champlain Bridge

Consortium Signature sur le Saint-Laurent, Amrize, Béton Provincial, VSL International
Montreal, Canada
2017-2018

SIMCO’s material expertise services were retained by various professional during the construction of the new Samuel De Champlain Bridge located in Montreal, Quebec. The new bridge project crossing the Saint Lawrence River was one of the largest infrastructure projects in North America, with a required service life of 125 years for critical components of the project.

Laboratory Testing Program to Ensure Concrete Mixture Compliance to Service-life Requirements

SIMCO carried out a series of tests on concrete samples produced in its ISO certified internal laboratory. SIMCO also participated in the development of various concrete samples and provided specialized technical assistance during mix production to meet project specifications. SIMCO’s services were selected to perform the complete characterization of the concrete mixtures that were designed in order to determine that they would comply to the requirements established by SSL Joint Venture.

Durability support during construction

SIMCO’s technical advice on durability was also sought throughout the project’s development by concrete producers and the Signature on the Saint Lawrence (SSL) consortium for evaluations of durability and service life requirements on various bridge elements (pre-cast elements, mass concrete elements, architectural panels, slabs, etc). Our mandates included: 

• Guidance on the usage of corrosion inhibitor
• Thermal stresses analysis and thermal control plan
• Technical support on pouring and curing activities
• Non-compliance repport resolution support
• Concrete durability and service-life calculations

During construction, SIMCO’s main objective was to provide optimal solutions in collaboration with all stakeholders to minimize the impact on the project’s budget and schedule.
