The seed that became CH2M HILL was planted in the mid-1930s, as three Oregon State College students, Holly Cornell, Burke Hayes and James C. Howland, came together under the influence of their civil engineering professor, Fred Merryfield. By mentoring his students outside the classroom, Merryfield cultivated the environment for an engineering partnership. After graduation and throughout World War II, Merryfield and his students maintained an active dialogue about a potential partnership. That partnership formalized in January 1946.

Today, CH2M HILL is a $3.8 billion design-build-operate company, committed to creating a better world through better people, technology, and project delivery. The firm's expertise is concentrated in the areas of water, wastewater, transportation, operations and management, government and military facilities, nuclear decontamination, and environmental services. The company also provides engineering and construction leadership in industrial facilities and infrastructure for clients in energy, power, electronics and advanced technologies, pharmaceuticals and biotechnology, manufacturing, chemicals, and communications and information technology.
