Video | First tunnel boring machine for Riyadh Metro

Watch the first of two FAST Construction tunnel boring machines put on site.

The first tunnel boring machine used to construct the Riyadh Metro system has been installed. Called Dhafrah, meaning victory in Arabic, it will drill up to 100m per week. As it moves forward it installs precast concrete segments as rings which form the tunnel lining.

Governor of Riyadh, Prince Faisal bin Bandar, started the first of two FAST Consortium tunnel boring last week. It will drill on the 12.9km tunnel between Riyadh Airbase and King Abdul Aziz Historical Centre. The Green Line features eleven stations and two endpoint transfer stations with the Blue and Red lines.

FAST Consortium is also building for the Yellow and Purple lines. The entire metro system is due to be completed in 2018. It will have 176 km of track and 85 stations. A total of seven tunnel boring machines will be used on the entire site.
