Project Case Studies

  • 140 Hearst Way – Franklin Empire – Seismic of T-Bar Ceiling

    Ottawa, Ontario

    New and renovated suspended T-Bar ceilings are subject to seismic requirements outlined within section 4.1.8.18 of the Ontario Building Code and the recommended guidelines of the Ceilings & Interior Systems Construction Association. Within the Franklin Empire building located at 140 Hearst Way, Cleland Jardien Engineering Ltd was retained to design the required seismic restraint system for the suspended T-Bar ceiling installed throughout the ground floor and second floor office area. The restraint system used on this project included cold formed steel studs as compression posts with four 45 degree splay wires and ACM7 Seismic clips around the perimeter to create the attached and unattached connections.

  • Minto Quarry Glenn and Ampersand, Seismic of Mechanical Occupational and Functional Components

    Ottawa, Ontario

    The seismic restraint of Occupational and Functional components is a requirement on almost all the new and renovation projects in the Ottawa Area. Minto Quarry Glen, in Orleans, and Ampersand, in Barrhaven, are two new communities which consisted of four storey, wood framed residential condominium structures. Due to the Building category of these structures, it was a requirement that all non-structural, occupational and functional components be seismically restrained in accordance with Section 4.18 of the Ontario Building code. The elements requiring the seismic restraints in these structures included, but were not limited to: piping, ductwork, in unit hot water tanks, heat recovery units, and air handling units as well as roof top condensing units.

  • Bayshore Shopping Centre, Seismic of Mechanical and Architectural Components

    Ottawa, Ontario

    In May 2012, the Bayshore Shopping Centre began a major addition and renovation project which included additional retail space, new parking garages and the relocation and renovation of many of the existing stores. Cleland Jardine Engineering Ltd was retained by various architects and contractors to working on the renovation and fit-up of the retail shopping unit and food court areas. Our services included the seismic design and review of architectural components such as bulkheads, drywall ceilings, store fronts, and security grills in Brown’s Shoes, Zumiez, and Swarovski. Within the brand new food court, we designed and certified the lateral bracing and seismic restraints for various exhaust hoods and store front components for KFC, Jimmy the Greek, and Teriyaki Experience.
