Six Companies
|
Six Companies, Inc. was the contracting firm that was formed to build Hoover Dam and later went on to build Grand Coulee Dam and other large projects. It was a consortium formed by six smaller general contractors in order to submit a bid for the Hoover Dam contract. Because of the immense size of the dam, no single contractor had the resources to make a qualified bid alone. Six Companies was composed of:
- Morrison Knudsen of Boise, Idaho,
- Utah Construction of Ogden, Utah,
- Pacific Bridge Company of Portland, Oregon,
- Bechtel Corporation of San Francisco, California,
- Kaiser of Oakland, California, and
- MacDonald-Kahn of Los Angeles, California
The dam was completed two years early, after a bid of $48,890,955.
