Building
the turbine barrel in the powerhouse, February 1964.
Thomas E. Petermann Collection (S-2005-89-140)
Not only were the T.L. James and J.A. Jones construction companies awarded the contract for the construction of the dam, they were asked to take on the powerhouse and switchyard project as well, after the company that originally won the bid was disqualified.
Although the James and Jones companies came to the project late, the milestone dates—dates by which certain portions of the project had to be completed—weren’t adjusted to reflect the delay. The contractor scrambled to begin the project in April 1963, finishing it one year later.
It helped that the contractor was using the critical path method (CPM), a newly developed system for scheduling a variety of activities in the least amount of time. Today such work is done by computer; in the early 1960s the monthly CPM chart was created manually.
