# CH2M

CH2M, earlier CH2M Hill, was an engineering company that provided consulting, design, construction, and operations services for corporations and governments. The company was organized in Corvallis, Oregon, and headquartered at 9191 South Jamaica Street, Englewood, Colorado. In December 2017, the company was acquired by Jacobs Engineering Group.
The company played a major role in the Panama Canal expansion project. The company developed, maintained and published its own method for managing projects for clients, called the CH2M Hill Project Delivery System. The firm was named from the initials of its four founders.

## History

CH2M was founded in 1946 in Corvallis, Oregon, by Oregon State University civil engineering professor Fred Merryfield and three of his students: Holly Cornell, James Howland and Thomas Burke Hayes. Cornell, Howland, and Hayes were all graduates of Oregon State University. The company became CH2M Hill after a merger with Clair A. Hill & Associates in 1971. The firm remained headquartered in Oregon until 1980, when it moved to Colorado.
