Emergency Department Design in Pakistan | ACCO
Designing an Emergency Department (ED) in Pakistan requires a meticulous blend of clinical efficiency, patient-centric flow, and strict compliance with national healthcare regulations. As the first line of defense in saving lives, the layout of an emergency room directly impacts clinical outcomes. In this comprehensive guide, we explore the core principles of emergency department zoning, mechanical, electrical, and plumbing (MEP) systems, cost estimations, and how ACCO (Architecture and Construction Company) delivers world-class medical facilities across Pakistan.
Why Professional ED Design Matters
Emergency departments are high-stress, fast-paced environments. Poor design leads to bottlenecks, delays in care, increased infection risk, and operational chaos. A professionally designed ED ensures seamless movement of patient stretchers, dedicated zones based on patient acuity, and optimal placement of lifesaving equipment. ACCO specializes in designing trauma centers and emergency rooms that meet international standards like FGI (Facility Guidelines Institute) and the requirements of the Punjab Healthcare Commission (PHC).
Key Zoning in Emergency Departments
Modern emergency rooms are organized into distinct zones based on the severity of the patient’s condition (Triage System):
- Triage Area: The entry point where nurses assess patients and assign priority levels.
- Resuscitation / Red Zone: For critical, life-threatening cases (trauma, cardiac arrest).
- Observation / Yellow Zone: For patients requiring monitoring, diagnostics, and short-term therapy.
- Ambulatory / Green Zone: For walk-in patients with minor injuries or illnesses.
- Support & Utility Zones: Nursing stations, clean utility rooms, dirty utility rooms, and diagnostics (X-ray, ultrasound).
Emergency Room Zoning & HVAC Requirements
Different zones require specialized environmental controls to prevent cross-contamination and maintain patient safety. The table below outlines these requirements:
| Zone Name | Acuity Level | Pressure Requirement | Air Changes / Hour (ACH) | Typical Equipment Needed |
|---|---|---|---|---|
| Resuscitation (Red) | Critical | Positive (+) | 15 – 20 ACH | Defibrillator, Ventilator, Crash Cart, Patient Monitors |
| Observation (Yellow) | Moderate | Neutral (0) | 6 – 8 ACH | Infusion Pumps, Central Monitors, Oxygen Supply |
| Isolation Rooms | Infectious | Negative (-) | 12 ACH (HEPA Filtered) | Negative Pressure Monitor, Portable X-ray, Oxygen |
| Triage / Waiting | Low | Neutral (0) | 6 ACH | Vitals Monitor, Patient Chairs, Reception Desk |
Space Allocation in Modern Emergency Departments
To optimize patient flow, spatial distribution is carefully planned. Below is a representation of standard space allocation within a state-of-the-art ED layout:

MEP and Medical Gas Systems Integration
An emergency department cannot operate without robust infrastructure. ACCO integrates core MEP systems directly into the design phase:
- Medical Gas Pipeline System (MGPS): Centralized oxygen, nitrous oxide, medical air, and vacuum lines are integrated into every treatment bay. Bedhead trunking systems are used for neatness and safety. Refer to ACCO’s specialized Medical Gas Pipeline Systems guide.
- Infection Control HVAC: HEPA filters and dedicated negative pressure units are installed in isolation rooms to contain airborne pathogens.
- Backup Electrical Power: Uninterruptible Power Supplies (UPS) and dedicated emergency generator circuits guarantee 100% uptime for ventilators, monitors, and lighting.
Estimated Construction Costs (ED in Pakistan)
The cost of building a high-standard Emergency Department in Pakistan varies based on materials, localization, and mechanical installations. A typical estimation is structured as follows:
- Civil Works & Grey Structure: PKR 4,500 – 6,000 per sq. ft.
- Specialized Hospital Finishes (Antibacterial PVC flooring, wall panels): PKR 2,000 – 3,500 per sq. ft.
- MEP & HVAC Systems (including Negative Pressure and HEPA Filtration): PKR 5,000 – 8,000 per sq. ft.
- Medical Gas Piping (MGPS Outlets): PKR 1,500 – 2,500 per sq. ft.
Expert Suggestions for Designing a Successful Emergency Department
Based on decades of engineering experience, ACCO recommends:
- Ensure Wide Corridors: Corridors in the emergency department should be at least 8 to 10 feet wide to facilitate the rapid movement of two stretchers passing each other.
- Proximity to Diagnostics: Place the ED adjacent to radiology (CT scan, X-Ray) and laboratory departments to minimize transit time for critical diagnostic tests.
- Flexible Layouts: Design observation bays with movable partitions so they can quickly be converted into trauma surge areas during mass-casualty incidents.
Frequently Asked Questions (FAQs)
Q1: What are the PHC requirements for emergency department design?
A: Punjab Healthcare Commission requires dedicated triage areas, separate resuscitation zones, isolation facilities, 24/7 power backup, and clean utility rooms with appropriate medical waste management systems.
Q2: Why is negative pressure required in ED isolation rooms?
A: Negative pressure ensures that air flows into the room but not out into the common corridors, trapping airborne contaminants inside where they are safely exhausted through HEPA filters.
Q3: Can ACCO handle both the architectural design and construction of trauma centers?
A: Yes, ACCO is a complete design-build firm, providing architectural design, structural engineering, MEP systems installation, HVAC setups, and civil construction under one roof.
