Included <br />are the cost of the feasibility study, the estimated 1990 costs of construction, contingency, <br />engineering, project cost escalation and interest. It is assumed that CWCB funding for the <br />project wiil become available in mid-1991, and that Option 1 project construction can be carried <br />out from June to November of 1993. Option 2 project construction is assumed to follow in two <br />years. <br /> <br />Costs are given for the two aiternatives selected by the City of Greeley. These are Option 1 . <br />Downstream Drainage Construction, and Option 2 - Partial Depth Slurry Wall. Option 1 consists <br />of that work required to bring the dam into compliance with current safety standards and <br />reasonable improvements to minimize potential maintenance costs. Option 2 - Partial Depth <br />Slurry is the cost of subsequently placing a partial slurry wall to reduce seepage losses from <br />the reservoir at some date following the completion of the Option 1 construction. The costs <br />shown for Option 2 are the lC. Shallow Soil Bentonite (low cost estimate). The work required, <br />as contained in the original unit price Option 2 cost estimate, in recognition that the Option 1 <br />work will be in place before the Option 2 work is started, include the following items given in <br />the Option 2 unit price cost estimate. <br /> <br />C.

For cost escalation and interest <br />during construction calculations, it is assumed that Option 2 will be constructed in 1995, <br />following construction of Option 1 in 1993. <br /> <br />Construction cost estimate details are at the end of this section. <br /> <br />6-1 <br />
