The project included the construction of 10,000 linear feet of drainage system to mitigate the intrusion of mine spoils into the natural stormwater drainage.
The Design-Build process implemented on the 7F-Wash project allowed Borderland to provide input on materials and construction techniques during the pre-construction phase of the project. Our collaboration with the owner and designer improved the project efficiency to meet the budget and schedule needs of ASARCO.
“…Arcadis was contracted by ASARCO Ray Operations to value engineer and redesign a major drainage diversion project that was constrained by both schedule and budget…During interviews with several contractors who had bid on the original design, Borderland presented the best ideas on how to reduce the capital cost of the project to within budget…The result was a revised conceptual design for the facility and a projected maximum project cost that was within ASARCO’s budget…I have been involved in a lot of capital projects in my 30-years as an engineer, and I have to say this was one of the smoothest, well-executed and safest construction projects I have experienced…All construction challenges were addressed in a collaborative, timely, and practical manner.”
