Appointed as the Principal Contractor, Gratte Brothers undertook a range of electrical services including the installation of new MV & LV switchgear, UPSs, generators, busbar, power distribution units, fire alarms, CCTV and access control. Mechanical services included the installation of a chilled water distribution system, VRF & DX cooling, water mist systems, leak detection, public health and building management systems. As Principal Contractor, Gratte Brothers also undertook all associated builders works, which included raised flooring, new offices, meeting rooms, plant rooms, fire rated risers, fire stopping and steelwork at Digital Realty Cloud House Phase 1.
Gratte Brothers was responsible for ensuring the environmental credentials of the project, which ultimately achieved a Building Research Establishment Environmental Assessment Method (BREEAM) rating of Excellent. Cloud House Phase 1 was registered under the Considerate Constructors Scheme (CSS), which encourages best practice beyond statutory requirements within the construction industry and formed the key basis for a credit within the BREEAM certification. Information around the materials used, site travel, commissioning methodology as well as the installation and implementation of sustainability initiatives was submitted to an external consultant for consideration over the course of the project with a bespoke travel calculator developed for the project to measure the environmental impact of our staff and site activities. Calculations included the distance travelled by the individual operatives on site, material deliveries and the waste management companies collecting skips from site. The project also recycled 100% of all on-site waste.
