Introduction: Why Modular OTs Are the Future of Healthcare Design

Operation Theatres (OTs) are the heart of a hospital. A well-designed OT can reduce infection, improve surgical outcomes, and streamline staff efficiency. Today, modular OTs are the preferred choice due to their precision-engineered components, hygiene benefits, and compliance-ready construction.

At Archora, we specialize in turnkey hospital solutions — and that includes NABH-compliant modular OTs that are efficient, future-proof, and tailored for critical care.

1. NABH Guidelines: What Does Compliance Really Mean?

The National Accreditation Board for Hospitals & Healthcare Providers (NABH) mandates clear specifications for:

• OT zoning and air pressure gradients

• Fire safety

• MEP services (HVAC, electrical, medical gas, plumbing)

• Surface finishes and cleaning protocols

Key zones include:

• Sterile zone: OT room, scrub area

• Semi-sterile zone: Pre-op, sterile storage

• Non-sterile zone: Dirty utility, corridor, patient holding

2. Modular Construction: Materials That Make a Difference

Modular OTs are made from prefabricated panels and standardized components. This ensures fast installation, low maintenance, and contamination control.

Common materials:

• Walls: PUF/EPS insulated panels with anti-bacterial coatings

• Flooring: Conductive vinyl or epoxy

• Ceiling: Laminar airflow-integrated false ceiling

• View panels: Toughened, double-glazed, flush-fitted glass

At Archora, we ensure all materials are anti-fungal, non-porous, and easy to disinfect, in line with NABH norms.

3. MEP Integration: Designing for Clinical Safety

A modular OT is only as good as its engineering backbone. MEP services need seamless coordination with modular structures.

HVAC Design Includes:

• Laminar Air Flow (LAF) system

• AHU with HEPA filters

• Air pressure differentials (positive pressure in OT)

Electrical Considerations:

• Backup power systems (UPS + generator)

• LED shadowless lighting

• Hermetically sealed electrical sockets

Medical Gas Lines:

• Oxygen, vacuum, nitrous oxide

• Color-coded pipe network with pressure gauges

4. Infection Control: Designing for Sterility

Modular OTs reduce infection by minimizing joints, cracks, and dust traps. But it’s not just about surfaces — it’s about system-wide sterility.

Infection Control Features:

• Seamless wall-to-floor coving

• Rounded corners and coved skirting

• Pass boxes for instrument transfer

• Hermetically sealed doors

• Copper ion-infused surfaces (optional)

Our turnkey OTs are designed in consultation with infection control officers and surgeons to ensure real-world functionality.

5. Technology Integration: Building Smart OTs

Today’s OTs demand tech integration. We provide smart modular OTs equipped with:

• Touchless sensor lighting and doors

• Integrated OT control panels

• CCTV and telemedicine support

• PACS compatibility for digital imaging

Conclusion: Turnkey Compliance with Design Precision

At Archora, we don’t just design OTs — we deliver NABH-ready, infection-proof, performance-driven modular operation theatres. Whether you’re upgrading a facility or building a new hospital, our team ensures regulatory alignment with architectural excellence.
