Barr Engineering Co.

Even before its incorporation in 1966, Barr’s founders were assisting mining and mineral processing clients with natural resource issues. Today, Barr offers one source for technical and regulatory services needed to take complex national and international mining projects of all scales from exploration, conceptual studies, environmental assessments, and permitting through detailed facility design, construction, operations, closure, and reclamation. Headquartered in Minneapolis, Barr has regional offices in 11 states and Canadian provinces—Minnesota, Michigan, Missouri, Colorado, Nevada, New Mexico, North Dakota, Utah, Washington, Alberta, and Saskatchewan.
