, I <br /> We believe that implementation of the above improvements <br /> will significantly improve the reliability of the proposed sewer <br /> improvements by reducing the dependence on raw sewage pumping. <br /> The revised plan can be readily expanded to serve future <br /> development in the transition areas and the industrial <br /> development along the 1-85 corridor. <br /> Estimated Construction Cost <br /> One of the primary objectives of the additional study by <br /> Hazen and Sawyer was to evaluate the construction cost estimate <br /> for the proposed Phase I sewer improvements. Our initial <br /> assessment indicated that the prevailing construction costs in <br /> the Orange County area were significantly higher than the unit <br /> prices used in the previous report. In order to confirm this <br /> possibility, we collected cost data from the Farmers Home <br /> Administration for a number of similar projects constructed over <br /> the last several months. The cost data was analyzed to determine <br /> typical or average construction prices for each element of the <br /> proposed sewer construction. These costs were then used to <br /> develop updated construction cost estimates for both the original <br /> Phase I sewer improvements plan and the Phase I improvements as <br /> modified by Hazen and Sawyer. The tabulated construction costs <br /> are included herein in Table 1. <br /> As suspected, the analysis indicates that the construction <br /> costs for both the original plan and the modified plan <br /> 9 <br />
