Since <br />this score is based on the product of PoF times CoF factors, it gives equal consideration for both factors. <br />Typically, different R &R strategies are applied to address these two considerations. <br />Based on the BRE heat map graphic results, the ranked sewer main assets were then grouped into <br />logical R &R strategies. Table C 3 defines each of these groupings and provides additional <br />summarizations and recommendations. Figure C 3 shows the same BRE heat map graphic as before, but <br />color coded by strategy group. Figure C 4 presents a map of pipe segments color coded by these strategy <br />groups. <br />[INTENTIONALLY LEFT BLANK] <br />BLACK & VEATCH I Appendix C Inspection and Replacement Cost Calculation <br />65B -272 <br />
