Many medical facilities have specialized clean rooms that can be used to prevent the spread of deadly diseases or to store medical supplies. These clean rooms may be built into the original structure or can be separate structures installed within the building. Cleland Jardine Engineering Ltd was retained to provide a structural review of one of these clean room structures which was installed within the Trudell Medical International Building in London, Ontario. The clean room consisted of a 30’ square box measuring 10’ tall. The structural elements of the room were built with extruded aluminum shapes connected together using nylon inserts at the connection points. Cleland Jardine Engineering Ltd reviewed all of the structural elements for dead loads of the room as well as the lateral loads imposed by seismic and interior wind pressures.
