Infrastructure Phasing
Sequencing power, services and plant so each clinical area opens when it is ready to.
Infrastructure phasing plans when physical infrastructure is delivered and commissioned across the lifetime of a hospital project: power, HVAC, medical gases, water and drainage, the IT backbone and plant. It maps each infrastructure item to the construction and commissioning phase it must be ready in, determines which infrastructure must be live before which clinical areas can operate, and where temporary provisions bridge the gap between phased construction and the permanent services. When temporary and permanent systems meet, it plans the tie-ins and changeovers so they are managed without disrupting operating areas. It also aligns infrastructure readiness with department phasing and future expansion, so a wing can open, operate and grow without rework to its services. As part of the Hospital Master Planning group, this service focuses on the sequencing and readiness of infrastructure across phases. It is distinct from infrastructure requirements, which defines what infrastructure the facility must provide in the first place, and from MEP planning, which engineers the systems themselves.
What this service covers
- Infrastructure items mapped to construction and commissioning phases
- Service prerequisites for each clinical area's opening
- Temporary versus permanent provision decisions
- Tie-in and changeover planning for power, gases and services
- Overlap management between operating and under-construction areas
- Plant and service room activation order
- Capacity ramp-up aligned with department phasing
- Future expansion provisions that avoid rework
- Infrastructure readiness criteria per phase
- Documented phasing plan as the project deliverable
Our process
- List the infrastructure services and their construction phases
- Define the infrastructure prerequisites per clinical area
- Decide temporary versus permanent provisions
- Plan tie-ins, changeovers and overlap controls
- Align infrastructure readiness with department expansion
- Document and maintain the infrastructure phasing plan
Frequently asked questions
What does infrastructure phasing include?
Deciding when infrastructure is delivered and live across phases: which power, HVAC, medical gas, water, IT and plant items must be commissioned before each clinical area can open, including temporary provisions and changeovers.
When is it needed?
During master planning and once construction phasing is decided, so infrastructure readiness is matched to each phase of clinical opening and expansion.
How does it differ from infrastructure requirements?
Infrastructure requirements defines what infrastructure the facility must provide. Infrastructure phasing decides the order, provisions and readiness of that infrastructure across the project.
How does it differ from MEP planning?
MEP planning engineers the mechanical, electrical and plumbing systems. Phasing sequences their delivery, commissioning and handover relative to clinical opening.
What inputs are required?
The construction and department phasing plan, the infrastructure requirements register, and the commissioning approach for power, services and plant.
