Geo-Exchange Retrofit Completed in partnership between F ē nix Energy and The Cadillac Fairview Corporation, the geo-exchange retrofit of 777 Dunsmuir in Vancouver is the world’s first installation in an occupied, mixed-use high-rise complex in a downtown core. The installation was completed in the lowest level of the parkade and the main mechanical room of the 19-storey office tower with no impact to building tenants. The geo field is composed of 34 boreholes measuring hundreds of feet below the parkade floor. By harvesting a building’s rejected heat and storing it underground until it is needed, geo-exchange offers a solution for reducing the energy costs and greenhouse gas emissions associated with traditional heating and cooling. The retrofit of Cadillac Fairview’s building is expected to reduce carbon emissions from heating energy equivalent to taking 190 cars off the road. 

Honolulu Rail Transit Project The Honolulu Rail Transit Project is a multi-phase light rapid transit project on the island of Oahu, Hawaii. It will provide a new public elevated transportation link between downtown Honolulu and the developing city of Kapolei (west island). Somerset Construction Engineering (SCG) designed the underslung girders and pier bracket ram assemblies for the span by span erection of the precast concrete guide-way. SCG is also providing construction engineering support to the contractor at special spans where custom falsework, temporary works and/or erection procedures are required. Owners: Honolulu Authority for Rapid Transit (HART). Client: Peter Kiewit Infrastructure. Somerset Engineers: Peter S. Saunderson, P.Eng., P.E.; Raymond Florendo, P.Eng., P.E.; Robert Gale, P.Eng., P.E.; Phil Sullivan, P.Eng.; Melody Tung, EIT; Jack Lam, EIT.

Railcar Unloading Improvements

West Coast Reduction, the largest independent renderer in Western Canada, operates a bulk storage and marine loading terminal in Vancouver to ship bulk oils, tallow and finished meal products internationally. Fats and oils from its Prairie plants arrive via rail to be unloaded and pumped to designated storage. A new railyard configuration created eight additional railcar unloading stations for a new total of 24 positions. This involved a rail spur; railcar unloading stations; new canola, tallow, steam, condensate, and compressed air distribution piping, and associated upgrades. The piping distribution network includes unloading stations, piping between the stations and a new pump house, piping between the pump house and various storage tanks, and steam and condensate piping from the steam boiler plant to the new distribution system. Project team: Geoffrey Glotman, P.Eng.; Ed Saiedi, P.Eng. (Glotman Simpson Consulting Engineers); Don McCulloch, P.Eng.; Bill Jenkins, P.Eng.; Milenko Vujicic, P.Eng.; Cameron McLennan, P.Eng.; Mohammed Shahrestani, P.Eng.; Petr Stryk, P.Eng. (AECOM).
