The new workplace required above-ground foul drainage serving tea points, staff pantries, the prayer room, cleaners' facilities and associated equipment. The available floor void and the position of existing connections made conventional gravity drainage difficult to accommodate.

The Stage 3 engineering strategy therefore called for wastewater to be pumped to a high-level route, before falling by gravity to the existing stacks within the WC cores. MPH's drainage package required careful coordination of pump locations, routes and connections with the surrounding building services.

The proposed foul drainage arrangement included separate high-level ventilation pipework connected back to the relevant core stacks. Routes also needed to accommodate access fittings, changes of direction and future maintenance.

Because these connections interfaced with retained landlord infrastructure, pipework setting-out and coordination with the wider mechanical team were central to a practical installation.

MPH's cold water package involved extending distribution from existing boosted cold water (BCWS) risers within the WC cores to new staff pantries, tea points, sinks and ancillary facilities.

The specified connection arrangements incorporated pressure-reducing valves, isolation and backflow protection, with solenoid isolation and pulse metering interfaces to the wider leak-detection and building controls strategy. These elements required coordinated setting-out and accessible valve positions.

The design adopted local electric point-of-use water heaters rather than a new central hot-water distribution network. The Stage 3 specification identified 10- and 15-litre units within low-level cupboards serving pantry, tea-point and other designated areas.

MPH's hot water package covered associated copper distribution and local equipment connections, with the engineering requirements addressing isolation, safety fittings and controlled outlet temperatures.

The architectural brief called for services to be discreetly integrated within partitions, furniture and constrained ceiling and floor voids, while maintaining practical access to valves, pumps and drainage components.

Across all three workstreams, MPH's involvement supported the integration of new public health infrastructure into the CAT B office layout and the existing building services.
