construction project available to interested parties at $5 a copy (equivalent to $ in ). The government would provide the materials, and the contractor was to prepare the site and build the dam. The dam was described in minute detail, covering 100 pages of text and 76 drawings. A $2 million (equivalent to $ in ) bid bond was to accompany each bid. The winner would have to post a $5 million (equivalent to $ in ) performance bond. The contractor would have seven years to build the dam, or penalties would ensue.
Because of the project's immense size and the fact that it was the first dam on the
Colorado River, no single contractor had the resources to make a qualified bid alone. So,

in order to submit a joint bid for the contract. Initially, Utah Construction Company's owners, brothers E.O. and W.H. Wattis, along with the company's vice president, Andrew H. Christensen, asked Harry W. Morrison of
Morrison-Knudsen to join them. After they realized the bid would be much higher than expected, the Wattis Brothers and Morrison-Knudsen convinced four additional companies to join. In February 1930 The Six Companies, Inc. was incorporated as a joint venture and they began working out a bid enlisting the help of Morrison-Knudsen employee
Frank T. Crowe to do so.
The project was so complex and large that only three bids were received and, on March 4, 1931, the
US Secretary of the Interior accepted the Six Companies' bid of US$48,890,955 (equivalent to $ in ). This was $5,000,000 lower than the next bidder, meaning a bid-spread of almost 10%.
The Six Companies board selected Crowe, who had helped draft the bid, as the General Construction Superintendent of the Boulder Dam construction. He was heavily involved and hired each of the men who were employed during the course of the project, lived in Boulder City with his wife and two daughters, and was on the dam site every day of the week until the project was completed.
Work began around June 1931 and The Six Companies completed the dam's construction two years ahead of schedule in 1935. Crowe was awarded a bonus percentage of the profit for completing virtually every portion of the job well ahead of schedule. The dam was dedicated in September 1935 but it took an additional nine years (1938–1947) under relative secrecy, to fix serious leaks with a supplemental grout curtain.
Six Companies Railroad
The Six Companies also built the Six Companies Railroad. It ran along the Hemenway Wash, present day
Las Vegas Bay, and connected to the US Government Hoover Dam Railroad at Lawler, Nevada, a location also known as "US Government Junction". From Lawler the railroad went north for to Saddle Island and then east to the Three-Way Junction gravel plant, now submerged under
Lake Mead. From the gravel plant the line split into two branches. One branch ran south for to the dam via Cape Horn, Lomix (the Low Level Concrete Mixing Plant) and Himix (the High Level Concrete Mixing Plant) and the dam face. The other branch, now also submerged under Lake Mead, ran north for across the Las Vegas Wash, crossed the Colorado River on a bridge into Arizona and the Arizona gravel pit (Arizona Gravel Deposits) at a location from
Callville.
The line was constructed by railroad contractor John Phillips of
San Francisco, California. Since the completion of the dam and filling of Lake Mead, Six Companies, Inc. railroad line is now submerged.
The
Western Pacific Railroad purchased several of the Six Companies dump cars for company service after the dam was completed and the equipment declared surplus. One of these cars is now preserved at the
Western Pacific Railroad Museum at
Portola, California.
The US Government Railroad had a branch that brought supplies by rail from a connection with the Boulder City Branch of the
Union Pacific Railroad at
Boulder City, Nevada.

During World War II, the Six Companies built airstrips and related facilities on Pacific islands. The venture also held a majority ownership interest in
