The document provides details on the construction of the Metro Route 2020 project in Dubai, which has a budget of $2.9 billion. It includes key project facts such as a route length of 10.5km for viaducts and 4km for tunnels. There will be 7 underground and elevated stations serving a capacity of 46,000 passengers per hour. Construction will involve tunnelling, precast segment erection, bridge and viaduct construction using methods such as diaphragm walls, secant piles and slipforming. The project execution plan outlines the construction process and measures to ensure safety, quality and environmental protection.

10. Advantages of Light Rail Systems Benefits of Metro to commuters
1. Time saving for commuters 4. Reduction in accident
2. Reliable and safe journey 5. Reduced fuel consumption
3. Reduction in atmospheric pollution 6. Reduced traffic congestion
13. Quarry & Aggregate Production
ⓒ David H Moloney
Brief Description
Rock is blasted free from the quarry
face and fragmented so it will fit into
the primary crusher. Any oversized
rock is broken with a excavator and
hydraulic Rockbreaker.
At the Crushing and screening yard
the fragmented rock is crushed and
screened into various size ranges.
14. Concrete Batching Plant David H Moloney
Concrete batching plant comprises -
concrete mixer, control cabin, silos for
cement and fly ash, aggregate bins and
conveyor belt system to feed the mixer.
Also aggregate storage bays and water
storage tanks.
The mixing is computer controlled and has
a dynamic screen display, showing the
process. Material storage capacity to
match two days concrete production

GeneralItems
Brief Description
Construction dewatering is the removal or drainage of
groundwater and or surface / rain water usually by
pumping to keep the works dry.

58. Viaduct Segments Casting David H Moloney
Casting Method
The concrete segments are manufactured
using the short-line, match-casting method.
Match-casting is when sequential segments are
poured against the previous cast segment, this
ensures that the segments will fit perfectly on
site.

70. Cut & Cover Tunnel Construction
Sequence -Traffic and utilities are diverted, excavate trench, construct & backfill to bury.
To prevent the faces of the excavation from collapsing, different measures are used –
batter the faces, diaphragm walls, secant piles or a combination of soil nailing and
shotcreting.
71. Ramp Construction
Sequence -Traffic and utilities are diverted, excavate, construct and backfill to sides.
To prevent the faces of the excavation from collapsing, different measures are used – batter
faces, diaphragm walls, secant piles or a combination of soil nailing and shotcreting.
