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.

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

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.
