Seismic retrofit of historic courthouse with precast concrete shear walls

The four-storey North Bay Courthouse building in Ontario was retrofitted with a new lateral force-resisting system (LFRS). The interior steel framing and slab connections were structurally strengthened to transfer seismic loading to 13 full-height, reinforced precast concrete shear walls around the building perimeter. Further, cracked masonry joints were repointed, damaged masonry units were replaced, and an elastomeric coating was applied over the entire wall surface.

Turning Retrofits into Success Stories with IMPs: A success story in the making

In London, Ont., a multi-residential apartment building built in 1970 was beginning to show significant signs of wear and tear on its exterior clay through-the-wall (TTW) brick, and owners had to develop a plan. Having already undertaken smaller localized repairs in the past, new water penetration issues on the upper, west-facing floors where the building is susceptible to driving rains, were cause to go in another direction.

Turning retrofits into success stories with IMPs

Driven by the principles of high-performance energy (HPE) buildings through government, energy codes, and the green building movement, building energy designs across Canada and around the world strive to improve. The increasing focus on the implementation of energy-efficiency requirements, for both new construction and deep energy retrofits for commercial and public buildings, begins with envelope-first energy efficiency, reduced energy demand loads, and related greenhouse gas (GHG) reductions.
