This $131.3 Million tailings storage facility expansion project was part of an on-going expansion of milling facilities. Though the scope of work for this EPC project was primarily civil work in the form of mass excavation and embankment construction and construction of a tailing pump system, AECOM’s scope also included civil, structural, mechanical, electrical, and piping elements. In all, approximately 80% of the work was self-performed by AECOM.
