For BHP World Minerals to restart its Pinto Valley copper mine near Miami, Arizona, it needed to upgrade its rail line in the nearby town of San Manuel, which is used to transport concentrate to a smelter in Mexico. However, BHP was low on budget, low on time, and needed a contractor with rail expertise to provide a turnkey, design-build solution quickly.


With nothing more than a Google Earth print-out of the site, Sundt worked with the owner to determine what needed to be demolished, rebuilt and upgraded. Within days we presented a design concept that included a responsible budget and realistic schedule. BHP awarded us a design-build contract and work began immediately. The team demolished the existing structures and rail cars; rebuilt a rail maintenance facility, depot and transfer station, and wet and dry utilities; and upgraded the concentrate storage facility.


In just 24 weeks from the first site visit with nothing but a concept in mind, we helped deliver BHP’s vision with responsible budgeting and responsive scheduling.
