Board approves $690,173.62 change order and final acceptance for 24–25 Grama sewer improvements

The board approved a final balancing change order (No. 3) for the 24–25 Grama sewer improvements project with Glossage Engineering in the amount of $690,173.62, adopted a related budget amendment, and authorized filing the notice of completion and release of retention within the lien period. Staff described the change order’s main drivers: unexpectedly extensive sag repairs (reverse falls requiring correction), rock excavation on some hillside reaches, method changes (switches between pipe bursting, open cut, and reaming), and county paving rules that forced full‑cul‑de‑sac paving in several county‑jurisdiction streets, increasing hot‑mix asphalt quantities and costs.

Phil Benedetti walked through the change order summary and noted several credits where method switches reduced costs but that overall additional work and county paving obligations led to an overage. Staff framed the closeout as a productivity success — the program rehabilitated miles of pipeline and reduced inflow & infiltration — while acknowledging the need to adjust capital budgets and realign reserves. The board approved the change order, adopted Resolution 26‑1684 to amend the FY25–26 budget, approved final acceptance, and authorized the manager to file the notice of completion.
