ACS awarded tunnel project in Canada

Dragados Canada will be responsible for the construction of 6.4 kilometres of CSST (Combined Sewage Storage Tunnel) tunnel in Ottawa

The ACS Group, in the framework of its strategy of growth and expansion in North America and Canada, has been selected by the city of Ottawa for the construction of a tunnel for the storage of storm waters worth 150 million Canadian dollars (approximately 101.5 million euros). The works started in September of this year, with completion expected in September 2019.

Dragados Canada, a subsidiary of ACS designated the winning bidder in the project, will build a tunnel of 6.4 km in length and 3 m in diameter, executed with a tunnel boring machine.
