Ems{ BUILDING SOLUTIONS, <br />Recommendations <br />The below table compares the proposed Tanko project to the project ABS would recommend to be <br />considered by the City. If the City considers these recommendations, the initial Acquisition / <br />Conversation project would be reduced by about $2,800,000. These recommendations would result in <br />about a $8,600,000 reduction over the 20 -year life of system life. These results and recommendations <br />are explained in further detail below. <br />LS-1 Acquisition Costs <br />Recorn.mencled <br />$3,679,122 <br />$3,895,693 <br />LED Conversion Costs <br />$3,184,799 <br />$5,686,015 <br />5 % Contingency <br />$343,196 <br />$479,085 <br />Subtotal <br />$7,207,117 <br />$10,060,793 <br />Rebate <br />$723,965 <br />$723,965 <br />Project Total <br />$6,483,152 <br />$9,336,828 <br />20 year Internal Maint.
