- **Government buyer:** City of Santa Rosa, Transportation and Public Works Department, Capital Projects Engineering Division; project site at Bennett Valley Golf Course, 3330 Yulupa Road.
- **Scope:** Upgrade the golf course irrigation supply, including two well-pump systems, piping, flow measurement, pressure control, electrical service, motor controls, and related site and restoration work.
- **OEMs and named companies:** **Grundfos** (pump basis of design); **AA Tanks, Amtrol, and Flexcon** (listed tank manufacturers); **Rosemount** (flow-meter basis of design); and **Cla-Val** (hydraulic control-valve basis of design). Approved equivalents are allowed. The geotechnical report was prepared by **Bauer Associates, Inc.** for **Brelje & Race Consulting Engineers**; **PG&E** is referenced for utility coordination.
- **Major equipment and quantities:** Two Grundfos 475S600-7 submersible pump systems, each with a Grundfos MMS 6 motor; one hydropneumatic bladder tank of at least 792 gallons; one Rosemount 8750W magnetic flow meter; one Cla-Val Model 92-07 pressure-sustaining/pressure-reducing valve with solenoid shutoff; 250 linear feet of 12-inch PVC irrigation main; and 12 transformer bollards.
- **Technical requirements:** Pump systems must meet specified operating capacities and at least 75% efficiency at design points, with motors rated 60–75 HP. The tank must meet specified operating and working pressure limits. The PVC main is specified as DR-18, pressure class 235, generally conforming to AWWA C900; ductile iron may be substituted at no additional cost.
- **Construction and site work:** Includes work at the North and South wells, wellhead piping, flow-meter and valve vaults, irrigation piping and tie-in, electrical service, MCC/PLC controls and telemetry, excavation, dewatering, shoring, erosion control, testing, startup, and restoration. Work must be phased to maintain irrigation service and limit shutdowns.
- **Geotechnical findings:** The supporting investigation finds the proposed irrigation pond geotechnically feasible and recommends a synthetic liner, planning for groundwater dewatering, subdrains, removal and recompaction of weak surface soils, and geotechnical observation during grading.
- **Performance duration:** Final completion is required within 130 working days after the Notice to Proceed. No option periods are identified.
