Knight Piésold USA was established in 1985 in Denver, CO and has become a leading consultancy providing engineering and environmental services in the mining and hydropower industries. Branch offices were established in Elko, NV (1989) and Tucson, AZ (2007), and a high-end laboratory offering state-of-the-art geotechnical testing is also located in Denver.

Our staff of highly qualified engineers, technicians, and support personnel provide engineering solutions to mostly private sector clients in the United States and around the globe, specializing in the design, construction, and operation of tailings dams, hydropower and water supply dams, open pits, heap leach facilities, and tailings delivery systems.

Our diverse staff, representing more than 14 different nations, works hard to provide superior products and excellent customer service to our clients. Our skilled specialists focus on developing innovative, cost-effective solutions that are tailored to the specific challenges of each project. Whether it involves mining in cold regions, hydropower supply in desert regions, or filtered tailings operations in the tropics, we get the job done. Our commitment to quality is evident in the repeat business of satisfied clients that trust us to do the job well, and to suggest and employ measures that will improve productivity, cost-efficiency, and safety.
