The building was formed from 75 modular sections over 3 stories complete with bridge links from/to the existing building. The base design for all supporting services which included the upgrading of an existing transformer within the substation, new LV switch room and associated switchgear, a back-up diesel generator located adjacent to the new switch room and existing substation, extension of the site fuel delivery system, upgrading of the existing gas main, BCW system extended from existing tank rooms, provision of medical gasses, BMS integration of all services, Fire alarms, security and access control.

The modular building included a dedicated plant room from which heating, cooling, ventilation and all domestic services requirements were controlled and fed. Gas heat pumps located on the roof of the new building formed an integral part of the buildings heating and cooling systems, the rest of the roof being given over to a large PV array.

Due to the nature of the project and its extremely tight programme, it involved a predominantly reactive approach with challenges on a daily basis due largely to logistics inherent in the environment of a 24/7 operational facility. A notable challenge came in achieving a gas service upgrade, involving working across 4 carriageways in a timeframe that had if not been for Covid and the absolute necessity to deliver despite the odds, would not have been achievable under normal circumstances. Additionally there was the procurement of the 1600kVA transformer from Turkey that required high level interfacing to overcome transport delays. All in all despite the challenges, the collaboration between Rose Building Services and Galliford Try along with their supply chain proved a great success.
