EXPERIENCE 

Gary was president and owner of Moltz Constructors, Inc. of Cody, WY, from 1989 till 2014, when he sold the company to its employees. For 25 years Gary managed diverse types of heavy civil projects, including the rehabilitation of dams, spillways & tunnels; water/wastewater treatment plants, fish hatcheries, and pipelines. He managed multiple large gate rehabilitation projects for the U.S. Bureau of Reclamation, including slide gates, ring follower gates, radial gates, and floating drum-style gates. Many of these projects were in remote locations with limited access through canyons, rivers, and rugged terrain. Heavy civil projects in the Rocky Mountains required mitigating the additional challenges of unpredictable weather patterns and working at elevations up to 10,000 ft. (See Moltz Constructors’ corporate resume 1989-2014 for a complete list and descriptions of these projects.)

Gary started Keo Civil LLC in 2014 to provide consulting services for design firms, government agencies, irrigation districts, and private landowners as they plan projects related to the construction or repair of dams, spillways, gates, valves, and hydroelectric projects.  Gary especially enjoys early brainstorming of project concepts for projects with tough access and other unusual conditions. His constructability reviews, problem-solving, and cost-saving ideas have made many projects more successful and safer. 

Extensive Government contracting experience, including the United States Bureau of Reclamation, the US Army Corps of Engineers, the US Fish & Wildlife Service, the US Post Office, and many State and Local Agencies.   FAR Experienced.
