Port of Montreal, Quebec

CONDITION ASSESSMENT & SERVICE-LIFE EVALUATION

The Port of Montreal is the busiest seaport on the St. Lawrence optimally exploit its facilities by ensuring the sustainability of Seaway that links the Great Lakes with the Atlantic Ocean, and its infrastructure. provides access to some 100 million Canadian and American consumers. The Port Administration is an independent federal In accordance to this objective, the Port Authority developed agency that was founded in 1999, to facilitate domestic and a management system for the inspection and maintenance international trade and contribute in achieving local, regional of its wharves. This management system, called “SGIQ”, was and national socioeconomic objectives. implemented to gather all information necessary to adequately assess the condition of its infrastructure; effectively plan The Port of Montreal is the pillar of a great international center corrective and preventive interventions required for the safety for transhipment of goods where export and import services of its users and proper functioning of its port facilities; and exceed 40% of Quebec’s international maritime trade. To remain finally, extend the service life of its infrastructure as well as competitive, the Port of Montreal intends on continuing to protect invested capital. CONDITION ASSESSMENT & SERVICE-LIFE EVALUATION

SIMCO’s scope of work was to conduct a comprehensive concrete was suffering from a combination of degradation investigation of the deterioration affecting the Port of mechanisms (ASR, freeze-thaw and corrosion), that would Montreal’s docks and concrete structural elements. More compromise the stability and integrity of Port of Montreal’s specifically, SIMCO was to fully characterize the mechanical structures in the mid-to-long term. Moreover, the numerical and transport properties of reinforced concrete, measure simulations performed using SIMCO’s STADIUM® software the depth of contamination by chlorides (originating from demonstrated that material durability falls short thus de-icing operations), identify other contaminants and assess significantly reducing the potential service life of the pier. the nature and extent of the damage affecting the material. SIMCO’s proposed changes led to more accurate diagnoses A detailed material characterization performed on Pier 36, was that will allow Port of Montreal to better identify future the basis for the development of an analytical approach and concrete degradation issues. Ultimately, the Port Authority recommendations for the integration of material components will have a more reliable understanding of its infrastructure to into Port of Montreal’s inspection and management system, ensure more effective planning of interventions necessary in in order to effectively assess the condition of its infrastructure. order to maximize investments. The analysis of the cores extracted, indicated that reinforced
