New Construction - Studies & Investigations

Project Case Studies

  • PWGSC: Supreme Court of Canada

    Ottawa, Ontario

    Engaged to do a seismic evaluation and options analysis for the Supreme Court of Canada, the project involved the analysis of the existing 200,000 ft² structural steel and masonry infill structure. A National Treasure with Heritage designation for interior and exterior features throughout complicated the ability to gather information regarding the composition of the building. CJE worked closely with PWGSC to perform minimal destructive testing on the building while still gaining insight into the building behaviours. An additional study was undertaken on the parking garage to assess the integrity of the podium, columns, and walls that are subjected to environmental degradation.

  • PWGSC: Jackson Building Seismic Study

    Ottawa, Ontario

    The Jackson Building is a 9 storey plus two-basement level structure composed of a reinforced concrete frame with brick cladding. A penthouse composed of a combination of structural steel and reinforced concrete framing with masonry infill is located on the roof of the building. The building as it stands today was constructed in 3 phases. The original building was constructed in 1919, with a 3-bay addition being constructed in 1941 and a penthouse addition/cladding replacement/floor infill being constructed in 1969. As the main building (1919) and its principal addition (1941) were designed prior to 1965, the structure was likely designed for wind loads alone without specific consideration for seismic forces. The updating of the existing Phase I, II, and III seismic study reports for the Jackson Building such that they reflect the changes in seismic assessment criteria in the 2005 National Building Code of Canada.

  • PWGSC: Central Heating and Cooling Plants Seismic Assessments

    Ottawa, Ontario

    Cleland Jardine Engineering Ltd. completed seismic studies of the Cliff Street, Tunney’s Pasture and Confederation Heights Central Heating and Cooling Plants in Ottawa. Gathering and review of existing drawings and reports, site visit to review the building’s structural system and non-structural elements, detailed 3-D structural analyses, evaluate building seismic force resisting system, blast resistance and the potential for progressive collapse were assessed for each facility. Various blast scenarios in terms of the explosive weight and blast proximity outside the plant were considered, review of functional/non-structural elements, as it relates to operational and life safety requirements.
