Total floor area

The new, complementary structure needed to include almost 10,000m² of client space, with a total floor area of 16,400m² spread over 7 floors, including 2 basements.

Service Solutions

Working as part of a construction consortium, Bouygues Energies & Services carried out the Mechanical & Electrical works for the delivery of this project. The first phase of the project included the completion of the electrical and mechanical installation on four levels of client space, as well as all technical rooms, and HV/LV risers.

Our solution included the following environmental controls air conditioning of all client spaces, technical rooms through approximately 200 Computer Room Air Conditioning Units (CRACs) and the complete chilled water supply and distribution via 15 chillers, 8 of which were installed as part of phase 1.

We also installed six 2900kVA generators as a back up power supply to general services and chillers, as well as BMS control for all technical systems, fire detection, inert gas fire suppression systems, access control and intrusion alarms to maximise network security, resilience and business continuity.

Benefits to the client

A single point of contact to boost performance. Providing detailed design, architectural, construction, procurement, mechanical and electrical services, and Integrated System Testing (IST) to assure the delivery of a world class facility.

Security and resilience. The facility construction has been designed and implemented to guarantee permanent continuity of seamless service under all circumstances.

The refurbishment was to take place over 3 phases, adding a total of 11,400m² of data hall space. The Phase 1 works were completed in the summer of 2012, comprising 4,100m² data hall space, plus associated technical rooms and office floors.

EQUINIX required the facility to be designed to offer a high degree of reliability and availability, with the capability of operating continuously, 7 days a week and 52 weeks a year.

Our Solution

Bouygues Energies & Services were appointed as the design & build partner for the further refurbishment works. Our solution included a double MV supply of 32MW, provided from 2 separate ERDF substations and a UPS system designed with N+1 UPS modules in each of the 4 strings. Each dual corded server was also supplied from 2 separate strings.

We ensured fuel storage tanks had the capacity to run at full output for 36 hours and designed all mechanical systems with N+1 redundancy, allowing maintenance within each system to protect the facility from equipment failure, offering business continuity.

We installed 1200 KW chillers with free cooling modules to ensure environmental controls , as well as building and electrical network monitoring systems (BMS / ENMS), fire detection, access control and CCTV for maximum facility control and security.

We also employed energy efficient design principles, improving Power Usage Effectiveness (PUE) to reduce cost and environmental impact.

Benefits to the client

A single point of contact to boost performance. Providing detailed design, architectural, construction, procurement, mechanical and electrical services, and commissioning to assure the delivery of a world class facility.

Energy efficient design. By designing the facility with the environment in mind, we were able to improve PUE, which reduces client running costs. Over 50% of electrical energy supplied to the facility is from renewable sources, further minimising environmental impact. 

Safety and security as priority. By implementing various features such as a back-up fuel tank, fire detection and chillers, the client can be assured that the facility is a safe and secure location to host their services.
