Dubai Metro
The Dubai Metro is a world-class, fully automated, driverless railway
system. The metro was constructed and delivered in two stages, the red
line (stage 1) and the green line (stage 2). In the congested central
areas of Dubai, the metro lines are mainly underground.
Red Line
Location: Dubai, UAE
Client: Road & Transport Authority
Designers: W S Atkins & Partners Overseas
Contractor: Obayashi Corporation, Japan Turkey Metro Joint Venture
Consultants: Systra Parsons
Duration: 2006 – 2010
The
Red Line is one of the two lines of the Dubai Metro network in Dubai.
This line is 52.1 km long, out of which 4.7 km is underground with four
stations. It runs from Al Rashidiya to Jebel Ali and travels along the
Sheikh Zayed Road for most of its length.
Encardio-rite was
awarded the instrumentation and monitoring work for the underground
sections. The scope of work included the supply of instruments,
installation with drilling, monitoring, surveying and data analysis with
daily, weekly and monthly reporting.
The work commenced in May
2006, with the deployment of about 20 experienced engineers, team
leaders and project managers who were stationed in Dubai for the
execution of these services. The project was successfully completed in
2010.
The instrumentation plan consisted of a large number of sensors for this massive project. It included:
- Inclinometers for diaphragm walls and sub-surface monitoring around stations.
- Magnetic extensometer for subsurface settlement monitoring around stations.
- Crack meters, tilt meters and building settlement points for structure monitoring.
- Pavement and ground settlement markers for monitoring surface settlement.
- Compression load cells for struts.
- Spot weldable strain gages for strut monitoring.
- Portable readout units with accessories including cables, switch/junction boxes, etc.
Green Line
Location: Dubai, UAE
Duration: 2007 – 2011
Designers: W S Atkins & Partners Overseas
Consultants: Systra Parsons
Client: Road & Transport Authority
Contractor: Obayashi Corporation, Japan Turkey Metro Joint Venture
Encardio-rite
was again awarded the instrumentation and monitoring work for the
underground sections of the Green Line on a turnkey basis. The scope of
work included the supply of instruments, installation with drilling,
monitoring, surveying and data analysis with daily, weekly and monthly
reporting for the geotechnical and geodetic instruments.
The Green
line is an underground line of 7.9 km with 6 stations. The work
commenced in April 2007 and was successfully completed in 2011. The team
was increased at Dubai to cater to both the Red and Green lines
simultaneously. The instrumentation plan for the Green line was similar
to that of the Red line.
For the Green line, Encardio-rite also
successfully executed the monitoring work of some overhead portions
including Jafza Limitless, where soil conditions required close
monitoring.
