Contract Operations
Since our first quarry operation in 1944, at the Barnhart Quarries in Oregon, we have successfully operated and completed projects while maintaining the highest technical, safety, and environmental standards.
- Our experience includes more than thirty locations worldwide covering nearly every type of commodity and production criteria.
- We take a proactive approach to equipment maintenance using the latest technologies to minimize breakdowns and reduce costly repairs.
- We provide cost competitive, efficient mining operations.
- We offer a full suite of in-house technical engineering and management services which ensure timely and efficient project execution.
Typically, our contract-mining assignments begin with short and long-term planning, equipment selection, and equipment scheduling. Production operations often encompass over burden removal, mining, and quality control. We also tackle the operation of facilities, including material handling, rail load-out, construction of access roads, and processing plants.
