Top 10: Mining EPC Contractors
The scope of projects delivered by contractors can encompass consultancy at pre-feasibility, well before final investment decisions (FID) are taken, supporting clients on project design and optimisation, as well as handling the procurement and installation of specialised machinery.
The scope of construction services extends from the provision of comprehensive services for developing mine sites through to initial earthworks and access roads to processing facilities and materials handling systems.
Great engineering, procurement and construction management contractors can suffer from anonymity like the best sports referees or umpires. But value versus cost considerations remain a factor as competition from regional contractors as well as lower cost Asian contractors increases.
Mining Digital has ranked 10 of the most experienced EPC contractors in the mining sector today.
