Mine Ownership and Operations Expertise
Kiewit is more than a construction and mining contractor, we’re also mine owners and operators. With over 75 years of direct operational experience, we bring an owner’s mindset to every project we touch.
Since entering the mining industry in 1943 with Bighorn Coal in northern Wyoming, Kiewit has developed a reputation for safe, efficient and cost-effective mine operations across the Western United States. Our experience owning and operating mines gives us a deep understanding of what drives success, from day-to-day production to long-term reclamation.
