MGS Tier 4 New Data Centre


Adamson Associates Architects were the architects to this Design, Build, Finance and Maintain consortium responsible for the design as constructed and are the Architects of Record

Delivered through a public-private-partnership (P3) method, this data centre was required to be a highly-available, fault tolerant, Tier 4 design in accordance with the requirements set out by the Uptime Institute. The primary objects for the project were to ensure the Ministry of Government Services are able to provide services to its (public sector) clients that are reliable, accessible, and cost-effective.

Smith + Andersen provided mechanical and electrical engineering and sustainability services from the genesis of the project (pursuit phase) with the development of system concepts to suit the requirements of the project specific output specifications (PSOS) and carried on through detailed design and construction.

The P3 delivery model of the MGS Data Centre assigned operational monetary penalties for significant deviations in the humidity levels. This elevated the importance of having the optimal construction, mechanical equipment, and controls required to comply with strict, indoor environment performance criteria. Although the ASHRAE Technical Committee 9.9 for Mission Critical Facilities, Data Centres, Technology Spaces and Electronic Equipment have continually widened the envelope for humidity control within the ""white space"" of Data Centres (e.g. ASHRAE Environmental Guidelines for Datacom Equipment), these ""relaxed"" standards were not adopted for the MGS Data Centre. The design had to achieve very stringent pressurization and humidity control to an absolute humidity level of 54 Grains of moisture per pound of dry air with little tolerance for change.

Along with stringent indoor environmental controls, energy conservation was also a key consideration in the design. The facility is designed to operate at an extremely energy efficient level of performance (often not associated with data centers) while still being high reliable.
