FAX NUMBER: 972 -304 -3570 City-of Co ell FROM: Erika Cooper PHONE NUMBER: 9721735 -3056 (if transmittal is incomplete or unclear, please call sender directly at this number.) REMARKS: Ken, Ted asked me to fax you the attached construction cost estimates for Force Main Line D for your review. We included five options. 1 Ductile iron force main installed by open cut with vertical pipe loop at Sandy Lake Lift Station and boring under trees 2. Ductile iron force main installed by open cut with vertical pipe loop at Sandy Lake Lift Station and replacement of trees 3. HDPE force main installed by open cut with vertical pipe loop at Sandy Lake Lift Station and boring under trees 4. HDPE force main installed by open cut with vertical pipe loop at Sandy Lake Lift Station and replacement of trees 5. HDPE force main installed by direction drilling The estimates are preliminary and were obtained primarily from local contractors. Although we cannot guarantee actual construction costs will exactly match these estimates, the estimates should provide sufficient accuracy to compare the five options evaluated. Feel free to call me at 972 - 735 -3056 or Ted at 972 - 735 -3048 if you have any questions. We look forward to discussing these estimates with you at your convenience.
