Infection control and staged access in operating facilities.

This changes the way the work is planned rather than the way it is built. The construction zone is sealed and held below the pressure of the spaces around it, so that air moves in rather than out. Entry and exit happen through an anteroom. Air is filtered and exhausted away from clinical areas. And the pressure differential is monitored continuously, because a control that is set up once and assumed is not a control.

The health service defines the risk level for the work and the precautions that follow. Our job is to build inside that framework and to give the infection prevention team something they can verify rather than something they have to trust.

Medical gases

Installation, modification and certification of medical gas systems are specialist, licensed work with their own verification regime. They are also frequently on the critical path because the certification cannot be rushed.

Imaging and shielding

Radiation shielding is designed by a specialist and verified after installation. It affects the structure, the door hardware, the penetrations and the room sequence, and it cannot be adjusted once the room is finished.

Essential and resilient services

Emergency power, uninterruptible supply, nurse call and medical monitoring cannot be interrupted casually. Every isolation is a clinical decision as well as a construction one.

Facility guidelines

Health projects are commonly designed to the health facility guidelines used in Australia and New Zealand, alongside the health service’s own standards. Building to a room data sheet is a different discipline from building to a drawing.

Finishes and cleanability

Coved junctions, sealed joints, impact resistance and surfaces that survive hospital-grade cleaning chemistry. Finish selection in health is a technical decision.

Commissioning and clinical handover

Rooms are handed over to a clinical team who need to be trained on what is in them, with the certificates in hand. We plan the handover as a stage rather than a day.

Every state licenses private health facilities separately, and each health service also carries its own capital works and design requirements above the licence. On top of that sit the national design guidelines that most public and many private projects are designed to, and, for a testing or research laboratory, an entirely separate accreditation and containment regime.

None of these is a builder’s approval to give. What a builder can do is know the sequence, get the evidence collected while the work is happening, and stop a project reaching completion with a room that cannot be licensed.
