Council approves Phase 2 sewer slip-lining change order adding pipe lengths; contingency reduced

Highland — The Highland City Council approved a change order on Aug. 5 to expand the second phase of the city’s sewer slip-lining project, adding additional pipe segments to be lined and adjusting contingency and top-hat allowances.

Public Works staff reported that finished work on Phase 1 returned savings (fewer top hats and lower contingency use than originally budgeted), and staff recommended using available funds to increase Phase 2 slip-lining linear footage. The contractor provided pricing for the added lengths and for additional pumping and traffic-control needs because one of the manholes is on North County Boulevard.

The council approved change order No. 1, an increase of $78,418.35, bringing the Phase 2 contract total to $341,316.20. Staff noted the slip-lining project is largely predictable in scope but that any additional top-hat (point-repair) needs beyond the revised contingency would require an additional change order and council approval.

Council voted in favor of the change order; staff said they will return if additional unanticipated repairs are required.
