The short answer
In short

Clinical precision
Every system that a surgeon relies on, built and proven
An operating theatre combines the most demanding environments in a hospital: a sealed, cleanable envelope; a laminar-flow ceiling with HEPA filtration and positive pressure; medical gases and surgical pendants; isolated power and UPS; conductive flooring; and lead lining where imaging is used. KRM delivers all of it under one contract, from the HTM / ASHRAE-based design to the witnessed tests.
Before you accept a theatre, our operating theatre handover checklist lists the tests and certificates the handover file should hold.
The team has delivered theatres and hybrid rooms for MOPA, MOHAP, SEHA, Burjeel, Medeor, Aster, Prime and Al Jalila Children's facilities — new suites, refurbishments inside live theatre blocks, day-surgery centres, endoscopy rooms and recovery and induction rooms.

Interactive 3D
Step inside a KRM operating theatre
Drag to look around and pinch to zoom, then tap a numbered point to see what each system does. Switch on the layers to watch filtered air sweep down from the laminar-flow ceiling and out through the low-level returns, or to see the walls, ducts, medical-gas pipework and power behind them.
Loads the interactive model (about 130 KB).
Illustrative model of a typical operating theatre, built from the systems KRM delivers. It is not a drawing of a specific project.
Filtered air flows down in a smooth, unidirectional stream over the operating table and carries particles away from the surgical site. HEPA filtration and positive pressure keep unfiltered air out of the room.
Theatre lights on ceiling-mounted arms, installed and connected by KRM and coordinated with the hospital's equipment supplier.
Surgical and anaesthesia pendants bring medical gases, electrical power and data down from the ceiling. Our biomedical engineer coordinates them with the supplier, and the pre-installation works are built to the supplier's specification.
Sealed antibacterial walls and ceilings with hygienic modular wall systems and stainless-steel fittings from KRM's own workshops, and lead lining where imaging is used.
Hermetic doors close the room tight so the pressure cascade holds between the theatre, the scrub area and the corridor.
Air leaves through return grilles near the floor, so clean air sweeps down over the table and out across the room. Pressure cascade, air changes and HEPA integrity are tested before handover.
Isolated power supply and UPS keep life-support equipment running through a fault, and medical-gas outlets are tested and certified. Electrical and gas test certificates go into the handover dossier.
Conductive flooring, stainless-steel scrub stations and integrated storage are part of the same contract, finished to the same hygienic standard.
Before and after
From bare shell to finished operating theatre
The same room at two moments: the bare shell we take over, and the theatre we hand back with modular walls, laminar-flow ceiling, medical gases, pendants and hermetic doors in place.

How we deliver
How a theatre is delivered
Theatres are usually refurbished inside a live surgical block — phasing and containment are planned with the hospital before a single panel is removed.
- 01
Survey, ICRA and phasing
Services tracing, infection-control risk assessment and a phasing plan that keeps the remaining theatres operating.
- 02
Design and approvals
Layout, HVAC, medical gas, electrical and lead-shielding design; DoH / DHA submission and Civil Defence approval.
- 03
Envelope and services
Hermetic doors, wall and ceiling systems, laminar-flow ceiling, pendants, gases, IPS / UPS and flooring installed to the coordinated drawings.
- 04
Testing and commissioning
Pressure cascade, air changes, HEPA integrity, medical-gas and electrical tests with certificates — witnessed by the client.
- 05
Licensing-ready handover
As-built dossier, O&M manuals, training and maintenance; support through the facility licensing inspection.

Questions answered
Frequently asked questions
Can you refurbish one theatre while the others stay in use?
Yes. We isolate the work zone with dust-tight hoarding and an ante-room, run HEPA negative air, isolate the HVAC, and agree out-of-hours windows for noisy work with the theatre manager and infection-control team.
Do you supply the pendants, lights and medical gas?
We install and connect them. Pendants, lights and gas outlets are coordinated with the hospital's equipment supplier through our biomedical engineer, and the pre-installation works are built to the supplier's specification.
What tests are carried out before handover?
Pressure cascade, air-change and HEPA integrity tests, medical-gas testing, electrical and IPS tests and fire-alarm interface tests, each with a certificate in the handover dossier for the licensing inspection.
What makes an operating theatre different from other hospital rooms?
It combines a sealed, cleanable envelope, a laminar-flow ceiling with HEPA filtration and positive pressure, medical gases and pendants, isolated power and UPS, conductive flooring and, where imaging is used, lead lining. Explore these systems in the interactive 3D theatre on the KRM home page.
