Cuajone, at the time of development, was the largest base metal mining project ever built by a single contractor.
Fluor was responsible for the engineering, procurement and construction management of the project. Fluor also provided feasibility studies, the basic mine plan, removal of over 250 million tons of overburden and initiation of the mine operation.
The infrastructure accounted for 50 percent of the total cost. Fluor built 62 miles of new railroad track, including 17 miles of tunnels. Of the five tunnels hewn, one is 9.15 miles long, the 4th longest in the world. Over 90 miles of new roads and expanded town communities in Cuajone, Botiflaca, and Ilo were created for new permanent housing, utilities, hospitals, schools, fire stations, and support services.
Power generation and transmission are vitally important to this remote site. Two hydro stations at the base of Lake Suche and the Ilo thermal power plant new 66-megawatt steam turbine generator provide electricity to a 138,000 volt closed loop transmission system. Waste heat is used for turbine generation and to flash evaporate seawater desalination plants for potable Ilo water supply.
To complete this huge complex on schedule, Fluor provided specialized training to more than 4,500 local workers.
