CH2M incorporated in 1966, so that ownership could more easily be spread between the growing number of partners.
The two companies formally merged in 1971, and the new name became CH2M Hill Ltd.
To enhance its growth on the other side of the continent, CH2M Hill acquired Black Crow & Eidsness in 1977, an engineering firm based in Gainesville, Florida.
By 1978, CH2M Hill had billings of over $50 million and had become the 10th-largest engineering firm in the country.
In 1988, three managers for one of CH2M's subcontractors on the project died in a gas explosion in a sewer tunnel.
In 1991 it formed a joint venture with an Australian company, Gutteridge, Haskins & Davey, to handle the growing market in water and wastewater treatment in Australia.
