Structure Tone constructs new subterranean data centre for university ranked Top 15 in the world

 

The project comprises the construction of a new subterranean data centre within an existing building.

The project has been commissioned by UCL as a result of the HS2 rail works directly impacting its existing data centre facility.

The building remained fully operational during the works along with two existing data centres, which were integrated into the new M&E infrastructure. This included co-ordination of the works around student exams and other sensitive periods critical to the customer’s day-to-day operations.

Phase 1 of the works included a package of demolition and enabling works to facilitate the construction of a new two-storey power building at lower ground (basement) level to house packaged substations, switchgear and standby generators and the construction and fit-out of a new data centre at sub-basement level, including six air-cooled chillers, primary and secondary chilled water distribution and associated ancillary services.

Phase 1 also included the delivery of a new UKPN 11kV power supply to provide additional capacity and resilience and consolidate a number of existing main power supplies to the campus. On completion of these works the existing two data centres will be transferred to the new M&E infrastructure.

Phase 2 of the works included the removal of the redundant sub-basement substations feeding the two existing data centres and completion of the remaining demolition, white space construction and fit-out.

A variety of cooling methods were selected for the data halls, including rear door coolers for high density (c. 30kW) data cabinets, in-row coolers with hot aisle containment for medium density cabinets and close control CRAC units for lower density cabinets. The system has been designed to ensure maximum efficiency is achieved and the UCL environmental targets are met.

Extensive structural reinforcement works were undertaken to enhance the general capacity of the data centre structure and surrounding plant areas, whilst maintaining maximum head space for 42u Racks to be utilised across the data centre.
