The Tor-1 Data Centre project data centre involved the construction of the largest wholesale colocation data centre in Canada within an existing facility. The program was an interior fit-out of 711,000 sq. ft. of existing space, complete with the addition of 46 MW of critical power capacity, and associated cooling and support services.

Phase 1 included the following:

  • 12 computer rooms (120,000 sq. ft.) complete with supporting critical power distribution spaces;
  • Shell built with redundant incoming utility, expandable generator plant and paralleling ring bus and UPS systems;
  • Designed and built for flexibility with potential configurations achieving resiliencies of N, N+1 and 2N, and a power density range of 1,076 to 3,228 watts per square foot;
  • Engineered to deliver a power usage effectiveness of 1.25 annualized at full capacity;
  • Extensive structural retrofit to account for the addition of 20 critical rooftop cooling units and supporting platforms;
  • Over 105 kilometres of conduit runs installed throughout the facility.

The 16-month fast-track schedule provided for demolition of the existing building interior, concurrent with the new fit-out of 12 computer rooms (10,000 sq. ft. each) with supporting power, cooling, communication spaces, staging, and office areas. A new 35,000 sq. ft. generator building with 24 MW of critical power capacity was constructed as an addition at the south elevation, housing all generators, supporting infrastructure, and paralleling ring bus with distribution.

A 520,000L fuel tank farm was constructed west of the building. The facility was designed for flexibility and performance, with computer rooms built-out to support power capacities between 1.0MW and 3.0MW per room. This was achieved with paralleling ring bus distribution throughout each computer room.

The design of the facility accommodates the phased build-out of additional computer rooms, generators, computer room cooling, critical UPS load, and critical power distribution without affecting the customer IT load.

This project achieved LEED Silver certification in 2020.
