Description
The project entails a design‑build effort to replace and upgrade sewer infrastructure at Auburn Valley State Park, including a new duplex grinder pump station, associated force‑main installation, and comprehensive site work. The contractor will be responsible for traffic management, erosion and sediment control, excavation (including contingent rock removal), concrete ballast for pump equipment, electrical service for the pump station, testing, start‑up, and delivery of operation & maintenance manuals. All work must comply with prevailing‑wage requirements, environmental controls, and vibration‑monitoring for adjacent historic structures.
• Construct a duplex grinder pump station with metering manhole and a simplex grinder pump.
• Install force‑main using open‑cut and directional‑drilling methods; minimum trench width 24 in.
• Perform site restoration (driveway, state roadway, off‑roadway) and provide erosion‑sediment controls.
• Provide electrical service (20 A, 240 V breaker, conduit, control panel) and complete de‑watering as required.
• Conduct commissioning, training, and deliver O&M manuals; monitor vibration near museum structures.
