ICU & Emergency Department Design in Hospitals | ACCO
The Intensive Care Unit (ICU) and Emergency Department (ED) are where hospitals save the most lives — and where design quality has the biggest measurable impact on mortality. Both departments demand 24/7 uptime, redundant systems, rapid patient turnover, and infection control at the highest level. Getting ICU design hospital right requires a specialised approach fundamentally different from general wards.
At Ahmed Construction Company (ACCO), we design and build ICUs, NICUs, CCUs, PICUs, and emergency departments to international standards. This guide covers everything from bed spacing and airflow to layout typologies and life-safety systems.

🏥 What Is an ICU?
An Intensive Care Unit is a specialised hospital unit providing continuous, high-intensity monitoring and life support to critically ill patients. Common types include:
- MICU — Medical ICU
- SICU — Surgical ICU
- CCU — Coronary Care Unit
- NICU — Neonatal ICU
- PICU — Paediatric ICU
- TICU — Trauma ICU
- HDU — High Dependency Unit (step-down)

📐 ICU Bed & Space Standards
- Open-bay ICU bed: 18–22 m² per bed with 2.4 m clearance around bed.
- Single-room isolation ICU bed: 25–30 m² with anteroom.
- Nurse-to-bed ratio: 1:1 or 1:2 for level 3 ICU.
- Central nurse station: line-of-sight to every bed.
- Isolation rooms: minimum 20% of ICU capacity.
- Family waiting: separate from ICU nursing area.

🌬️ ICU HVAC & Infection Control
- 6–10 air changes per hour, HEPA filtration.
- Positive pressure for general ICU beds.
- Negative pressure with anteroom for airborne isolation.
- Temperature 22–24 °C, humidity 30–60%.
- Independent AHU per ICU zone to isolate contamination.
- Hand-hygiene stations at every bed and entry.
—
⚡ ICU Electrical, Medical Gas & Equipment
- Every ICU bed on UPS-backed critical branch (< 10 ms transfer).
- Headwall panel with O2 (2), Vacuum (2), Medical Air (1), power outlets (16–20), nurse call, data.
- Ceiling pendant on cardiac and surgical ICU beds.
- Central patient monitoring: every bedside monitor connected to central station.
- Ventilator, infusion pumps, dialysis-ready outlets at each bed.

🚨 Emergency Department Design
ED Layout Zones
- Ambulance dock (covered, ground-level, direct access).
- Triage room adjacent to entry.
- Resuscitation bay (2–4 bays with full equipment).
- Acute treatment cubicles.
- Observation / short-stay beds.
- Minor injury / fast-track zone.
- Direct access to CT, X-ray, laboratory, trauma OT.
- Family waiting and quiet room for bereavement.
Emergency Department Sizing
| Annual ED Visits | ED Area (m²) | Treatment Cubicles |
|---|---|---|
| < 20,000 | 350–500 | 6–10 |
| 20,000–50,000 | 500–900 | 10–20 |
| 50,000–100,000 | 900–1,500 | 20–35 |
| > 100,000 | 1,500–2,500 | 35–60 |

⚖️ Open-Bay vs Single-Room ICU — Comparison
| Parameter | Open-Bay ICU | Single-Room ICU |
|---|---|---|
| Observation | Direct line of sight | Requires glass walls / cameras |
| Infection Control | Higher cross-contamination risk | Excellent isolation |
| Patient Privacy | Low | High |
| Family Presence | Limited | Full |
| Cost | Lower per bed | Higher per bed |
| Modern Standard | Legacy | Preferred (WHO/JCI) |

❓ Frequently Asked Questions
How much does building an ICU cost per bed?
PKR 3.5–6.5 million per ICU bed including civil, MEP, medical gas, headwall, and finishing (excluding equipment).
What is the ideal ICU bed-to-nurse ratio?
1:1 for Level 3 (highest acuity), 1:2 for Level 2, 1:3 for HDU.
How many isolation rooms should an ICU have?
Minimum 20% of total ICU beds, per WHO recommendations.
Can ACCO retrofit an existing ward into an ICU?
Yes. We assess structure, MEP capacity, and ventilation feasibility and produce a retrofit plan.
What airflow pattern is used in ICU?
Positive pressure with HEPA-filtered supply and low-level return for general beds; negative pressure with anteroom for airborne isolation.
