MPH undertook the mechanical drain-down and strip-out elements of its package to prepare existing installation areas for the revised office arrangement. These enabling works preceded the modifications to the heating and cooling connections.

Working with retained building infrastructure required careful coordination of access, the boundaries of the alterations and the interface between services being removed, adapted and retained.

The third-floor FCUs operate on a four-pipe arrangement, with separate chilled water (CHW) and low-temperature hot water (LTHW) flow and return circuits. The new Category B layout required the existing terminal connections to be adapted to revised equipment positions.

MPH modified the FCU pipework, coordinating changes at sub-branches and final connections with the retained distribution, existing service routes and surrounding ceiling installations.

Revised fan coil locations also required condensate services to be added and existing routes altered. MPH installed additional condensate pipework and rerouted sections to suit the changed FCU arrangement.

The connections needed to be integrated with retained discharge routes and competing ceiling services, with attention to practical pipework routing, access and the wider refurbishment sequence.

The public health package included domestic cold water pipework and connections for the reconfigured third-floor accommodation, including tea points, kitchenettes and other staff facilities. These services were integrated with the building’s existing boosted cold water supply.

New distribution routes had to be coordinated with partitions, ceiling spaces and the fit-out, with suitable service isolation and access considered at the connection points.

MPH also undertook the domestic hot water pipework and connection works associated with the new office facilities. The project specification set out hot water provision for general outlets and a separate first-aid-room arrangement.

The installed pipework interfaces were coordinated with the cold water services and surrounding furniture and fit-out requirements, allowing the refurbished spaces to be served from the revised domestic water network.

The works brought together enabling strip-out, four-pipe FCU adaptations, condensate modifications and domestic water distribution within a retained base-build environment. Existing riser locations and adjacent services influenced installation sequencing and pipework routes.

By focusing on targeted alterations and carefully coordinated connections, MPH supported the third-floor refurbishment without requiring wholesale replacement of the building’s wider mechanical distribution.
