Route 2020 a joint project between Acciona and Gulermak has
now completed 50% of the tunnel drilling works of the project. Acciona and Gulermak are jointly responsible
for the civil engineering. This part of the project is in charge of the 15
km Dubai Metro Red Line extension from Nakheel Harbour and Tower station to the
Expo 2020 ground including 7 stations, two of which are underground, the
Nakheel Harbour interchange station and the iconic Metro station located at the
Expo grounds.
In February the Herrenknecht TBM named Wugeisha Expo 2020,
which is 9.66-m diameter and 100-m long,
arrived at the future Jumeirah Golf Estates underground station. The TBM
started in Nakheel’s Al Furjan area and passed under Sheikh Mohammed Bin Zayed
Road before reaching the underground station. It will continue tunnelling works
up to the Dubai Investments Park (DIP) covering 3.2 km total at a depth of
between 12.5 and 36 m. In 2.5 months the TBM, whose cutter head has 56
cutters, advanced on average 13 m/day,
with up to 28 m of tunnel completed in a single workday.
To reduce completion times, the TBM was pre-assembled
outside the access shaft, with final assembly completed onsite. A new method
was also used to allow tunnelling very close to the surface, avoiding the use
of deep access shafts and incorporating significant innovations in the
manufacture of the lining rings to prevent water filtration. The Route 2020
Project is technically very complex and the BIM methodology is being applied to
every aspect of the design and execution phases.
All the tunnelling works will be completed by December 2018
and construction work on the Metro’s viaducts will be completed in November
this year. All rail works on the Route 2020 project will be completed before
summer 2019 and the system dynamic tests with trains will start during the
summer of 2019.
On the 22.03.2018 the Government of Dubai's Department of
Finance (DoF) announced the successful completion of a 17-year financing deal
of AED 9 billion, used to complete the construction of Dubai’s Metro Route 2020
extension project. The transaction consists of a 17-year AED 5.2 billion loan
supported by comprehensive guarantees from the French export credit agency,
Bpifrance Assurance Export S.A.S (BPIAE) and the Spanish export credit agency
(CESCE). Repayments will be over 14 years commencing in 2020 and a 10-year facility
of AED4 billion, with repayments over six years commencing in 2022. Click here for a video, here and ae/20 for tunnelbuilder archive. Visit and http://www.acciona-construccion.com
