Chuquicamata, located in northern Chile, is the world’s largest open pit mine and will require 63km of tunnel excavation, 7km of shafts and the transportation of 3.6 million tons of materials to convert to an underground operation. Construction works will be finished in 2021.

"With this project, our subsidiary Züblin will expand its current presence with Codelco," said Thomas Birtel, CEO of Strabag. "Besides the Chuquicamata Mine we are also working on the El Teniente Mine and in the Andina Mine. Our many years of experience in the mining sector in Chile are very appreciated by our client,"
