Service life

The non-destructive test method developed in this study can be used to assess the quality of a newly installed membrane system or to determine the membrane condition at various points during its service life with the intent of optimizing maintenance interventions.

This research project developed software using probabilistic life-cycle deterioration models for RC structures. It assesses current conditions and predicts future performance using field data, enabling effective scheduling of maintenance or repairs to extend the asset’s life. The software evaluates various deterioration stages, enhancing asset management.

Built in 1910, the Moose Jaw Inland Grain Terminal stands as a multi-cellular, concrete-constructed grain facility. Recent evaluations hinted at potential corrosion from concrete carbonation, prompting a proposal for extensive rehabilitation.

The Petrofka Bridge, a significant steel and concrete structure over the North Saskatchewan River, showed signs of wear, prompting an in-depth examination beyond regular evaluations to inform its upcoming major rehabilitation.

The historic University Bridge in Saskatoon, established in 1916, was slated for an extensive rehabilitation in 2015 to renew its deck, arches, and piers. This initiative is backed by an in-depth assessment, focusing on prospective strategies for enhancing the bridge’s arches.

This study evaluates various rehabilitation strategies for the University Bridge in Saskatoon, focusing on arches and piers. Methods like Fiber Reinforced Polymer wrap, Cathodic Protection, Re-alkalization, and others were evaluated using experimental data on concrete properties and environmental conditions informed numerical models. A recommended synergistic mitigation strategy combining Galvanic Cathodic Protection and a Penetrating Sealer could save $2-4 million.
