Centaurus Mall, Islamabad

The Centaurus Mall in Islamabad is a complex, high-profile development where the implementation of MEP (Mechanical, Electrical, and Plumbing) systems has been a subject of significant public record. The information reveals a dichotomy between the sophisticated engineering solutions installed and persistent regulatory and safety concerns.

Here is a breakdown of the MEP solutions based on available information:

HVAC (Heating, Ventilation, and Air Conditioning)

The HVAC systems in the Centaurus complex are extensive and varied, designed to meet the needs of different areas:

• Mall & Apartments: The system incorporates a mix of technologies, including Chilled Water systems and VRV (Variable Refrigerant Volume) systems to serve the shopping mall and residential apartments. Installation work has included fans (FAHU's), pumps, air handling units (AHU's), fan coil units (FCU's), and extensive ducting networks .

• Hotel Basement Car Park: A dedicated, high-performance ventilation system was installed for the Mövenpick Hotel's basement parking. This system, delivered by Welkin Solutions using Systemair products, uses 12 tube axial fans and 27 jet fans. Its design was validated by CFD (Computational Fluid Dynamics) analysis to ensure effective smoke control and pollutant extraction, meeting both local CDA regulations and international hotel standards .

• Tower Safety: Installation of a Stairwell Pressurization System in Towers A and B has been implemented to maintain smoke-free escape routes during a fire .

Fire Fighting Systems

The fire fighting systems have a complex history, with documented installations alongside serious reported deficiencies and a major fire incident.

• Installed Systems: Work has reportedly included the installation of firefighting MS (Mild Steel) seamless piping (1" to 6" diameter), various sprinkler types (upright, pendant, concealed, side wall), fire hose reels, and fire extinguishers. Hydrostatic pressure testing of the pipeline at 350 Psi was also conducted
