Doha Metro, Gold Line

The construction of the Doha Metro Gold Line in Doha comprises 2 x 11,7 km TBM tunnels and 10 stations by cut and cover methods (with 3 additional stations as an option). The karstic subsurface can lead to high water inflow rates in some areas. With a contract value of 3.1 bn EUR the Gold Line represents the biggest construction lot for the new metro system.
