. . '~ ' -.\ width, with an extension of the outlet pipe through the proposed spillway, and a stilling basin with energy dissipation blocks, The project bid process in July 1997 resulted in the receipt of only 1 bid, 27' percent over the Engineer's Estimate. Despite Left Hand's attempt to negotiate a lower' price with the bidding contractor, as well as with a qualified contractor who did not' submit a bid, they were unable to arrive at a construction cost within their estimated budget. Left Hand's board of directors decided to cease further negotiations in August, 1997, try to arrange further financing and postpone construction of the project until' September 1998: Due to Left Hand's good faith effort in attempting to make the required improvements to the spillway, the State Engineer's Office has approved this revised construction schedule, A /Stl, During a regularly scheduled maintenance inspection of the dam outlet works in September 1997, it was discovered that approximately 20 feet of the 30 inch steel outlet. pipe, near the maximum section of the dam, was partially collapsed. The upstream slide gate of the pipe was also discovered to leak appreciably.' The most economical, and recommended, solution to this problem is to slip-line the outlet pipe with ,a 24 inch diameter, heavy wall,"polyethylene'pipe' and. repmr the slide gate'leak as part of the spillway project when the reservoir is de-watered for construction. Based on the August 1997 bid, subsequent negotiations, and proposed outlet pipe repairs, the revised project cost estimate follows: Redesigned Project Spillway Construction Outlet Pipe Slip-Lining and Gate Repairs Construction Observation and Administration 5% Contingency 3% Inflation Factor $600,000 $ 50,000 $ 40,000 $ 35,000 $ 22.000 Total Estimated Project Costs 'c.$747 000; , ' . Left Hand has requested an increase to their loan in the amount of $190,000 for a total loan amount of $560,000, or 75% of the total project cost. DISCUSSION This project required a redesign from the original design proposal due to unforeseen requirements associated with the acquisition of a federal wetlands permit. The revised design avoided disruption of a wetlands area, however resulted in an increased project cost. Paragraph (2) of Section 1 ofHB 95-1155 allows that loans made by the Colorado Water Conservation Board may be increased or decreased as may be justified by "reasons of changes in the plans for a project if those changes are required by final engineering drawings and specifications". Final engineering of this project has
