Board told LTCP Phase 5 mainline near completion; staff warns $300K–$350K in change orders coming
Summary
Staff reported about 500 linear feet of sanitary mainline and 1,100 linear feet of storm mainline remain; mainline work is projected to finish by mid-December with other work by February. Staff said unsuitable subsurface material and utility coordination created extra excavation costs estimated at $300,000–$350,000 and that change orders will be on
Sanitary board staff updated members that construction on the Long-Term Control Plan (LTCP) Phase 5 is nearing its mainline completion but that additional costs have emerged that will be brought to the board for approval in December.
Project engineer (S4) told the board: "They have about 500 linear feet of mainline left to install, and they have 1,100 linear feet of storm sewer mainline to install." He projected that the contractor would finish the mainline install by mid-December and complete the remaining work by February. Board member (S2) asked for clarification on the dates; the engineer reiterated the mid-December and February targets.
Public works staff (S5) explained why change orders are forthcoming: as crews excavated for new storm and sewer work they encountered very poor road material caused by years of leaking sewer, storm and water mains. "We had to haul all that material out and replace it with stone," S5 said, and added that in many locations geofabric was used to stabilize the pipe. Staff estimated: "There's probably 300 to 350,000 in in extra excavation and stone and stuff." Staff also said coordination with other utilities—specifically the location of a gas line and discovering the placement of fiber-optic cable—required sequencing changes that resulted in delays and additional costs.
Staff confirmed contingency funds exist to cover some of these costs but told the board that formal change-order paperwork and a detailed cost breakdown would be provided at the December meeting for board action.
The board approved pay application No. 9 and a consultant invoice later in the meeting; staff emphasized the change orders could affect future payment schedules and will be considered before further disbursements.
