Four new hospital floors.
Built directly above a live emergency department.
The approximately $800 million Princess Alexandra Hospital expansion has reached another major visible milestone, with scaffolding coming down as four new floors emerge above the hospital’s operating emergency department.
Structural construction has already topped out. The focus is now shifting inside — toward fit-out, building services, medical infrastructure, systems integration, commissioning and operational readiness.
For the construction industry, that transition reveals what makes this project unusual: the new hospital capacity has to be delivered while critical healthcare services continue immediately below it.
The outside is becoming visible. The work is moving inside.
Metro South Health says the exterior of the PA Hospital expansion is approaching completion as scaffolding progressively comes down around the new structure.
The four-storey expansion sits above the existing emergency department and follows structural topping-out in May 2026.
That milestone marked completion of the major structural frame.
The August update signals the next transition: preparing the spaces, services and systems required to bring the expanded hospital into operation.
Why building above a live emergency department changes everything
PA Hospital is one of Queensland’s busiest tertiary hospitals.
Construction therefore cannot be treated like a conventional greenfield hospital build.
Patients, emergency clinicians, ambulances, essential services and existing hospital systems need to continue operating while major construction occurs directly above and around them.
The emergency department could not simply be shut down
The need to preserve critical clinical operations fundamentally changes sequencing and access.
That is why staging, temporary arrangements and communication between hospital teams and construction teams have been central to delivery.
A 15-stage decant strategy helped keep patient care running
Metro South Health’s latest project update highlights an innovative 15-stage decant strategy used to enable critical infrastructure works without interrupting patient care.
Decanting in a hospital environment means more than moving desks. Clinical teams, treatment areas, services, equipment and supporting infrastructure can all need carefully sequenced temporary or permanent relocation.
The strategy allowed critical infrastructure works to advance while hospital services continued operating.
Structural completion shifts attention to services, fit-out and commissioning
A hospital shell does not become clinical space until an extensive network of systems is installed, integrated, tested and accepted.
The final stages therefore bring a different construction profile from the concrete and structural phase.
The visible structure is only one layer of a functioning hospital
Fit-out and services integration can involve thousands of interfaces before a clinical area can be occupied.
Commissioning then has to prove that those systems operate safely both individually and together.
From structure to functioning clinical space
John Holland is delivering the expansion in one of Brisbane’s most sensitive construction environments
John Holland is the Managing Contractor for the PA Hospital expansion and remains on site delivering the project.
The company’s wider healthcare portfolio emphasises construction within operating hospitals where existing patient services must continue throughout delivery.
At PA Hospital, that requirement is particularly acute because the major new floors have been constructed directly above the emergency department.
What the expansion ultimately adds
The project will deliver 249 new overnight beds, including 30 ICU beds.
It also includes 13 new oncology treatment bays, expanded pharmacy and medical imaging services and refurbishment of admission and recovery areas supporting the cardiac catheter laboratory.
Metro South Health also identifies expansion of kitchen and other support capacity.

The complexity is now moving from concrete into systems
Four new floors above an operating emergency department is already an unusual construction problem.
But structural completion does not remove the most sensitive interfaces.
The project now has to turn those floors into functioning clinical environments while the wider hospital remains operational.
Mechanical and electrical systems must be completed. Clinical infrastructure must be installed. Existing systems need to integrate with new systems. FF&E needs to arrive in the right sequence. Commissioning has to verify performance without compromising patient safety.
Metro South Health’s 15-stage decant strategy demonstrates how deeply hospital operations and construction sequencing are linked on this project.
That makes the PA Hospital expansion a useful example of why healthcare construction demands specialist capability across staging, services integration, temporary works, logistics, clinical fit-out and commissioning — not merely structural construction.
