NFM Technologies News Release
-
NFM EPBM will work on the Red Line 3 project
- NFM Technologies has confirmed supply of a 10.16m diameter EPBM to the consortium awarded construction of the Metro Riyadh Red Line 3 in Saudi Arabia.
- The consortium comprising Impreglio SpA of Italy, Larsen & Toubro Ltd of India, and Nesma & Partners Ltd of Saudi Arabia has the contract to build the 40.7km of Line 3, the longest of the project. Line 3 runs in the east-west direction across the Saudi Arabian capital city Riyadh, with 20 stations and a 6km underground section.
- The NFM machine weighs 1,400 tonnes and is 100m long and will excavate a single-tube, double-track running tunnel for the system at a maximum depth of 40m through soil composed mainly of limestone and loam.
- The machine will be built, assembled and tested in the NFM workshops in Le Creusot, Burgundy, France and will be ready for delivery to the client this Summer.
- Valued at an estimated US$22.5 billion, the 176km Riyadh Metro investment covers the largest metro programme under development in the world at present, with procurement of six-lines and 85-stations grouped into five design-build packages that include supply of the rolling stock and installation of M&E in each.
- Preliminary designs for the near-180km system were carried out by consultants Dar-Al-Hanasah of Lebanon and Egis Rail of France. These base the network on 35.2km of bored running tunnels with a further 13.7km of cut-and-cover work for a total subsurface length of nearly 50km.
- Construction on all the lines is schedule to begin in this first quarter of 2014 with the project scheduled to be complete and in service during 2019.
