The intention of the project was to create a world-class office complex for the clients staff, with the replacement of critical end-of-life M&E infrastructure supporting the new fit out floors. New mechanical, essential and UPS power was to be re-distributed throughout the building with a new BEMS system monitoring building power consumption. The old out-dated SCADA network was upgraded with new hard and software. New PLC controls and remote monitoring were installed to control the startup sequences and load shedding of the 4 generators sets. A full refurbishment of the data centre PDU Supplies and cooling was carried out whilst the room remained live.
Metropolitan carried out the procurement, installation, and commissioning of the mechanical and electrical service elements within the infrastructure package, whilst supporting the other side of ISG’s project, the fit-out phase. All infrastructure upgrade works have been completed throughout the building whilst the bank was in full operation. The programming, procurement, delivery, installation, and commissioning all took place without any disruption to the clients business. The works have included the installation of new busbar power distribution and tap off units, complete with the migration of old services on to new, and the subsequent strip out works and firestopping. Structural openings have been designed, signed off, constructed, and bunded to enable the installation of rising services. New LV switch panels have been installed upon newly-constructed concrete bases. Mechanically the works have involved fan upgrades, fire damper upgrades, AHU refurbishments, and Data Centre Cooling systems.
Whilst carrying out upgrade works to the ‘BAU’ equipment and plant, Metropolitan's work was primarily to support the ISG fit out construction phase, ensuring that all milestones within their programme were met. Added to this challenge, was the discovery that all the existing Schneider Rising Busbars [XL Range] were no longer available, and when tap off units were removed, the existing mouldings were damaged and therefore unable to be re-used.
This required a new design approach, which resulted in Anord Mardix creating new tap off units out of what could be salvaged from the existing units. The existing tap offs were removed during planned shutdowns and migrations so that they could be reinstalled to critical equipment at set milestones. This discovery also required new LV switch panels to be designed, manufactured, delivered, cabled and commissioned all in line with the fit-out construction programme.
