Modern OT Design & Renovation in Islamabad

An operation theatre is the most technically demanding room in any hospital. Many private and public hospitals in Islamabad and Rawalpindi were built with theatres that no longer meet current expectations for air quality, infection control, power security or equipment. Modern OT design and renovation in Islamabad is about bringing those rooms up to date without shutting the hospital down for months. This guide explains what a modern operation theatre needs, how a renovation is planned and phased, which standards apply, and what hospital owners and surgeons should decide before work starts.

Why Islamabad Hospitals Are Upgrading Their Operation Theatres

The twin cities have a large and growing number of private hospitals, specialist centres and day-surgery units. Many of them started in converted buildings or older blocks where the theatre was a normal room with split air-conditioners, tiled walls and a ceiling light. That arrangement makes it hard to control infection and almost impossible to meet modern surgical expectations.

The most common reasons owners decide to renovate are:

• Infection control. Split units recirculate unfiltered air and cannot hold the room at positive pressure.
• Licensing and inspection. Regulators increasingly look at ventilation, zoning and finishes during inspections.
• New specialities. Orthopaedic joint replacement, cardiac, neuro and laparoscopic surgery need more space, more power and better air quality.
• Equipment. Ceiling pendants, integrated video systems and modern anaesthesia machines need structural support, data cabling and clean power.
• Running costs. Old cooling equipment and poor insulation waste electricity, which is expensive in Pakistan.

What a Modern Operation Theatre Needs

Controlled air and pressure

Air quality is the foundation of a modern OT. A dedicated air-handling unit supplies filtered fresh and recirculated air through a laminar airflow or unidirectional ceiling directly above the operating table. Final HEPA filters remove fine particles, and the room is held at positive pressure relative to the corridor so that air flows outwards, not in. Temperature and humidity are controlled within a range that suits both the patient and the surgical team. Our guide to hospital HVAC and infection control explains these systems in detail.

Hygienic surfaces

Walls and ceilings should be smooth, non-porous and joint-free as far as possible. Modular steel or high-pressure laminate panels and seamless vinyl or epoxy floors with coved skirting are common choices. Doors are usually hermetically sealed sliding doors that reduce air leakage and avoid hand contact.

Medical gases and pendants

Oxygen, nitrous oxide where used, medical air, surgical air and vacuum are delivered through pendants or wall outlets, with zone valve boxes and alarms outside the theatre. Anaesthetic gas scavenging is also required. The medical gas pipeline design guide covers this in more depth.

Power and lighting

Theatres need a secure electrical supply: generator back-up, a UPS for critical equipment, and an isolated power system that reduces the risk of electric shock to patients. Shadow-free LED surgical lights and good general lighting complete the room.

Supporting rooms

A theatre does not work on its own. It needs a scrub area, sterile store, clean and dirty corridors or a clear clean-dirty separation, anaesthesia induction where possible, and a recovery area close by. Links to the CSSD must also be planned.

Standards and Approvals for OT Work in Islamabad

There is no single Pakistani rulebook for operation theatres, so designers combine local requirements with recognised international standards. In practice this means:

• Facility licensing through the Islamabad Healthcare Regulatory Authority for hospitals within the federal capital, or the Punjab Healthcare Commission for facilities on the Rawalpindi side.
• Building permission from the Capital Development Authority, a housing society or a cantonment board when structural or external changes are involved.
• Ventilation designed to ASHRAE 170 or equivalent healthcare guidance.
• Electrical and medical gas safety to NFPA 99 and HTM principles.
• Fire safety following the Building Code of Pakistan and NFPA life-safety principles.

Owners should check current requirements with the relevant authority before finalising the design, because rules and inspection practices are updated over time.

Renovation vs New-Build Operation Theatre

How an OT Renovation Project Runs

Keeping the Hospital Running During Works

Most hospitals cannot close every theatre at once. Good phasing is therefore as important as good design. Typical measures include sealed temporary partitions with negative pressure inside the work zone, separate routes for workers and debris, work in noisy trades scheduled outside surgical hours where possible, and daily cleaning of adjacent corridors. Infection-control staff should agree the plan before the first wall is opened. Once the renovated theatre is commissioned, it is cleaned and tested before the next one closes.

Common Mistakes in OT Renovation

• Installing a laminar flow ceiling without a dedicated, correctly sized air-handling unit
• Ignoring the ceiling void, so ducts and gas pipes cannot fit and the ceiling ends up too low
• Choosing wall and floor finishes on price alone, then seeing joints crack and harbour dirt
• Leaving the recovery area, scrub area or sterile store undersized
• Skipping commissioning tests and relying on visual inspection
• Upgrading the theatre but not the generator, transformer or UPS that supply it

How ACCO Approaches OT Projects

ACCO has worked in construction since 1998 and provides hospital design, MEP engineering and construction from its office in Gulberg-III, Lahore, for clients across Pakistan, including the twin cities. On theatre projects the team starts with a site survey and clinical brief, prepares coordinated architectural and MEP drawings, and prices the work through an itemised BOQ. Construction is planned around the hospital’s operating schedule. Wider renovation work is covered under hospital renovation and upgradation services, and complete projects under turnkey hospital construction.

Conclusion

A modern operation theatre combines clean, pressure-controlled air, hygienic finishes, secure power and well-planned medical gases with a layout that supports the surgical team. For hospitals in Islamabad and Rawalpindi, a carefully phased renovation can deliver that standard without stopping surgery. The key is to fix the clinical brief early, design the HVAC and services together, and test every system before the theatre goes back into use.
