22 Bishopsgate is a prominent City of London commercial tower. The AMWINS Level 9 East refurbishment required existing building services to be adapted for a revised office layout, including new fan coil connections and a relocated tea point.
Working under Mala Engineering, with Overbury as Principal Contractor, MPH delivered targeted chilled and low-temperature hot water alterations, new condensate connections and public health pipework, including a practical solution to restricted drainage-stack access.
CHW & LTHW modifications • FCU condensate drainage • BCWS to relocated tea point • Jung Pumpen pumped discharge
MPH modified the existing chilled water (CHW) and low-temperature hot water (LTHW) distribution pipework to provide connections serving eight fan coil units within the refurbished Level 9 East office area.
Working with established building systems meant assessing practical connection locations, service clearances and routes to the revised terminal equipment positions without unnecessary disturbance to the wider network.
The mechanical alterations also introduced condensate pipework serving the fan coil units. MPH routed the new drainage to an available connection on the existing building drainage stack.
The installation required coordination between terminal equipment locations, the available pipework routes and the infrastructure already in place in the ceiling and service zones.
The new tea point required a fresh boosted cold water supply (BCWS) connection. MPH adapted the existing service within the tenant riser, extending pipework to the tea point’s revised position.
The connection was integrated with surrounding services and the office fit-out, enabling the new amenity to be served from the building’s established boosted cold water network.
A direct new connection to the vertical drainage stack was not accessible at the required location. MPH instead developed a workable installation route using an existing high-level waste pipe.
A Jung Pumpen pumped wastewater arrangement enabled discharge from the relocated tea point to that elevated pipework connection, resolving the access constraint while retaining the required tea point position.
