High Voltage Electrical Distribution Upgrade
HH Angus was the M&E Engineering Consultant on the original design and construction of the iconic TD Centre, and we have been working with Cadillac Fairview ever since, designing ongoing upgrades and improvements to this landmark site, Canada’s first skyscraper.
HH Angus was retained as Prime Consultant to replace existing transformers at the Toronto Dominion Centre’s Towers 1, 2 and 3, with the replacement of 600V switchgear. Our mandate was to implement this infrastructure renewal with no impact to services or disruption to tenants at the fully-occupied buildings.
The project scope included preparation of specifications, drawings and contact documentation for the removal of numerous 2000 kVA PCB oil-insulated transformers and replacing them with dry-type transformers. Because PCB is a designated substance, stringent procedures were required for handling, rigging and disposing of the transformers. Careful attention was paid to construction sequencing to ensure continuity of services during weekend shutdowns for switchgear replacement.
Extensive rigging procedures were also required for removal of the old equipment and installation of new units, as the transformers were located in both the basement and penthouse of each building.
