Dubai Metro
The Dubai Metro is the world’s longest automated, driverless metro system, setting a benchmark for urban transit in the Middle East. The project has significantly improved transportation infrastructure in Dubai, easing daily commutes for thousands of residents and workers.
The Red Line and Green Line were developed in two phases:
Phase 1 – Red Line (2006-2009):
- Length: ~53 km
- Stations: 26 (Including 4 underground stations)
- Underground Section: 5.6 km
Phase 2 – Green Line (2007-2010):
- Length: ~18 km
- Stations: 14 (Including 6 underground stations)
- Underground Section: 7.9 km
These lines traverse major commercial and residential areas, running underground in the city center from Sheikh Rashid Road to Oud Metha Road.

Construction & Tunneling
The underground metro system was constructed with minimal impact on nearby buildings, requiring an extensive instrumentation & monitoring (I&M) plan to mitigate risks.
Challenges & Solutions
1. Underground Excavation & Tunneling
2. Structural Monitoring & Settlement Control
- Geotechnical instruments installed to monitor ground behavior in real-time.
- Predictive analysis of settlement & soil deformation ensured safety.
Instrumentation Used for Monitoring
A comprehensive monitoring system was implemented to track ground movement, structural stability, and environmental factors.
| Instrument | Purpose |
|---|
| Inclinometers | Monitored lateral movement behind diaphragm walls & tunnel alignments. |
| Standpipe Piezometers | Tracked groundwater levels in and around stations. |
| Magnetic Extensometers | Monitored subsurface settlement during excavation. |
| Strain Gauges & Load Cells | Measured stress/load variations in structural supports. |
| Surface Settlement Points | Tracked ground settlement in excavation zones. |
| Building Settlement Points | Ensured buildings within zone of influence (ZOI) remained stable. |
| Tilt Meters | Monitored rotation & tilt of buildings due to tunneling. |
| Crack Gauges | Detected crack widening in structures near construction. |
📌 Monitoring Duration: 4 years
📌 Key Impact: Data-driven construction adjustments ensured safety & prevented damage to existing infrastructure.
