Our large blue chip client asked us to provide a new data suite, segregating a space in a larger data hall to provide a smaller space. They asked us to act as Principal Contractors and create the new space, requiring full construction and M&E services throughout.
Metropolitan set up site in a cabin external to the building, and installed safe routes from a separate security entrance prior to works commencing. The works consisted of a full electrical and mechanical fit out of the space, including installation of 4nr PDUs fed from main switchboards, 8nr CRAC units, containment, and cabling throughout the data hall at high level. Submain supplies to the new PDUs were via existing and new ladder rack run through corridors from the existing substation locations and then in to the hall at high level. Extreme care had to be taken to ensure no dust could be transferred into other halls or communal spaces as these areas remained live throughout. Armoured cabling was used to power the PDUs and the cables were terminated on planned shutdowns organised between Metropolitan and the client. All shutdowns had built in back out plans for any unforeseen cirumstances that could have meant stopping works for a period of time. All outgoing ways were installed to the new Cab locations (installed by IT), with commando sockets being installed in an A & B arrangement to each cab. The CRAC units and PDUs were installed on new plinths with local floor modifications being carried out. All pipework and drainage was run at low level from a local connection point as part of a previous project phase and Metropolitan ran new cold aisle containment throughout the hall.
