William Coates replaced the existing R22 Air conditioning system on the 3rd, 4th and 5th floors.
The building remained fully operational and occupied throughout the duration of this project. Works were carried out, out of house via night shift and weekends. The process of changing over was programmed and phased in coordination with BT Personnel. New AC indoor unites were installed within the ceiling and ducting to new grilles attached. Outdoor AC units were installed on the 6th Floor roof plant area. These were craned into position. Modifications to existing pipework and final connections to both indoor and outdoor units was carried out during weekend shutdowns, ensuring all site requirements were fully operational for Monday morning starts.
