Board authorizes supplemental engineering contract for phase 2 changes, including additional pump

Staff asked the board to authorize Supplemental Amendment No. 19 to Walker Partners/Flint Nichols JV to provide engineering services for a series of owner‑requested change orders on the phase 2 raw water delivery project. The largest proposed addition is the inclusion of an extra pump for operational redundancy at higher pumping elevations; Roberts characterized it as a sixth pump and gave a ballpark cost for that pump in the $6.5–$7.0 million range for the pump itself while the amendment for engineering services is an hourly contract with a maximum cost of $332,586 funded from the phase 2 contingency.
