Replace Structure 17 1 ea. at $10,500 ea. = $10,500 Replace Structure 18 1 ea. at $10,500 = $10,500 Repair 19 & 20 1. ea. at $1,000 = $2,000 Miscellaneous $50,000 TOTAL STRUCTURE REPLACEMENT COSTS = $180,000 We, therefore, have an estimated rehabilitation cost using concrete lined ditch of $2,602,000. Since all engineering will be done by the Soil Conservation Service, all we need to add are funds for contract administration and legal fees. For this study we will estimate this at three percent (3%) of the total construction costs. For alternative No.2, this will be about $78,000. We, therefore, have a total estimated cost of $2,680,000. As can be seen, this is higher than the $2,400,000 available for the rehabilitation of this project. There would be areas which could not be rehabilitated due to lack of funds. The areas which would have to remain earthen would be picked on their existing conditions, with the best sections remaining. Those reaches of ditch with extensive deterioration would be attended to first. The remainder of the ditch which cannot be concrete lined under this project, should be budgeted for as soon as possible. We recommend that the portion of the ditch which must remain earthen be stripped, shaped and compacted until the time it also can be reconstructed with concrete lining. 30
