Relocate plant and phase works while the building stays live.
Existing rooftop plant is relocated and new services threaded to the extension in phases that keep the facility operational throughout. Sequencing around continuous occupation is the core constraint for extensions over live healthcare buildings.
When extending above a building that remains operational, the existing rooftop plant cannot simply be displaced — it must be relocated in a sequence that maintains services continuity throughout, with new systems threaded to the extension in phases around the live occupation. This is less a standalone innovation than a constraint that shapes every decision on the project: the phasing plan becomes the dominant design driver, and the sequence of plant moves, temporary service routes and construction access must be resolved before the extension design itself can be finalised. The record makes no performance claim and carries no evidence, which reflects its nature — it is a project management and coordination methodology rather than a product. The genuine value of naming it explicitly is that it forces the design team to treat continuity of services as a first-order constraint from inception, not a construction-stage problem. The risk for a specifier is underestimating the time and cost of phased plant relocation: on a healthcare building the consequences of a services outage are severe, and the programme contingency required to manage that risk adds materially to the project duration and cost.
