SENER is the company providing the Independent Checking Engineer (ICE) services for package 3 of the Riyadh Metro in Saudi Arabia. and was awarded the contract in 2014 by FAST, the consortium responsible for the design & build project of lines 4, 5 and 6. FAST and SENER are working together under the umbrella of the Client, Arriyadh Development Authority (ADA).

The design is currently in its final production phase, with 90% or higher completion in most of the project packages. This contract has a wide scope and very tight deadlines, thus requiring an intense focus from the design team to avoid delays in the construction work. The members of the consortium are currently reviewing and controlling the different design and work procedures used with a view to guaranteeing compliance with requirements, regulations, interfaces, construction processes and quality controls. 

With respect to the construction phase, the TBM (Tunnel Boring Machine) tunnel and a large number of the viaducts are complete. Work is now focusing on the depots and on the elevated and underground stations. Construction of the installations is scheduled to commence next year.
