NFM Technologies Signs First Saudi Arabian Contract

Crews will use an NFM EPB TBM to construct a 6-km underground section of a new transit system through the capital city of Riyadh, Saudi Arabia.

NFM Technologies has just signed an agreement with the Metro Riyadh Line 3 Ltd. consortium to supply a 10.16-m diameter tunnel boring machine to excavate the Red Line of the Saudi capital’s metro system.

The consortium features companies such as Impreglio SpA, Larsen & Toubro Ltd. and Nesma & Partners Contracting Co. Ltd. It is responsible for building 40.7 km of Line 3 (Red Line), the longest of the project. Line 3 runs in the east-west direction across Riyadh, with 20 stations and a 6-km underground section.

To excavate the tunnel, NFM Technologies will supply an earth pressure balance tunnel boring machine. Weighing 1,400 tonnes and 100 m long, the boring machine will excavate at a maximum depth of 40 m, in soil mainly composed of limestone and loam.

The machine will be built, assembled and tested in the NFM workshops in Le Creusot, France. Delivery to the client is scheduled for this summer.
