The project consists of <br />replacing the upper portion of the dam with a new concrete overflow section that can <br />withstand overtopping by the design storm, Without completion of the project, the State <br />Engineer's Office was prepared to impose a storage restriction, <br /> <br />The DDRC bid the construction portion of the project and received three bids, The lowest <br />bid exceed the engineer's estimate by $203,000 (31%), The Colorado Construction Cost <br />index increased 15% between the time the Feasibility Study was completed (1997) and <br />the project was bid (1999). In addition, the DeWeese Reservoir site is located in the <br />mountains and is difficult to access. Construction bids in 1999 have typically exceeded <br />the engineer's estimate for these types of projects. <br />
