Like a handful of other companies on this list, CH2M Hill had its genesis in the early half of the last century. Holly Cornell, James Howland, and T. Burke Hayes – the C and two Hs – were students at Oregon State College in the mid-30s when they met the M, civil engineering professor Fred Merryfield. In 1946, they founded a company that today employees more than 23,000. The company’s name was rounded out in 1971 when CH2M merged with Clair A. Hill & Associates. Recent projects for the full-service global engineering firm have included a contract in 2007 for the $5.25 billion expansion of the Panama Canal.
