NFM Technologies will supply an EPBM. Weighing 1,400t and 100m long, the TBM will excavate to a depth of 40m in soil mainly composed of limestone and silt.
The machine will be built, assembled and tested in the NFM Technologies workshops in Le Creusot, Burgundy. Delivery to the client is scheduled for this summer.
The consortium features companies including Impregilo SpA, Larsen & Toubro and Nesma & Partners. It is responsible for building the 40.7km of line 3, the longest of the project. Line 3 runs in the East-west direction across Riyadh, with 20 stations and a 6km underground section.
