MEP Works: The Lifeline of Modern Buildings

MEP (Mechanical, Electrical, and Plumbing) encompasses all systems that bring a building to life: from electrical wiring and mechanical installations to plumbing and HVAC systems. These works typically represent 40-60% of the total project cost, making execution quality a critical factor.

Electrical Systems

Mechanical Systems

Extra Low Voltage (ELV) Systems

ELV systems operate below 50 volts and include:

CCTV Surveillance Systems

Modern cameras incorporate AI for facial recognition and behavior analysis, offering 4K+ resolution with cloud storage and remote mobile access.

Fire Alarm Systems

Classified into conventional and addressable systems. Addressable systems pinpoint fire location with per-sensor accuracy, significantly reducing response time. They include smoke detectors, heat detectors, manual call points, and sounders.

Data and Communications Networks

Design and implementation of Structured Cabling infrastructure per TIA/EIA-568 standards, including fiber optic and copper cabling (Cat6a/Cat7), server rooms, and wireless access points.

Access Control Systems

Smart cards, fingerprint, and facial recognition systems controlling entry and exit, with complete movement logging integrated with surveillance systems.

The Importance of MEP and ELV Integration

True success lies in integrating all these systems within a single platform—fire systems communicating with HVAC to stop ventilation during fires, and cameras integrating with access control to record video at every entry.
