Site work and renovation of a municipal facility in Kalamazoo, Michigan. Completed plans call for the renovation of a municipal facility; and for site work for a municipal facility.

Removal of existing failed wastewater pump and installation of a new high-capacity industrial grinder pump, including adaptation of the discharge line from a 2-inch format to the existing 6-inch cast iron infrastructure main line. The objective of this project is to restore the operational integrity and reliability of the municipal wastewater lift station located at the City Hall building for the City of Kalamazoo. The Contractor shall provide all labor, materials, equipment, tools, supervision, and incidentals necessary to safely remove and dispose of the existing failed pump, install a new high-capacity industrial grinder pump, and modify the discharge piping system to transition from a 2-inch discharge connection to the City's existing 6-inch cast iron force main. All work shall be performed in accordance with applicable industry standards, manufacturer recommendations, and all local, state, and federal regulations. Upon completion, the lift station shall be fully operational and capable of providing reliable wastewater service for the City Hall facility. Phase 1 : System Isolation & Decontamination Electrical Lockout/Tagout (LOTO): Isolate and verify zero energy states at the main 460V, 3-Phase control panel following OSHA safety guidelines before beginning any mechanical or electrical disconnects. Fluid Level Management: Coordinate system isolation to manage upstream wastewater inflows. Draw down or pump out residual wet well fluids to expose the pump base and discharge piping. Wash Down: Wash down the internal workspace and targeted equipment with clean water to mitigate biological and chemical hazards prior to extraction. Phase 2: Equipment Extraction & Removal Mechanical Rigging: Setup a mobile gantry hoist, crane truck, or portable rigging hoist directly over the lift station hatch access point. Disconnection: Disconnect the heavy-duty 460V power and sensor cords from the junction box/panel. Unbolt the discharge flange assembly. Pump Extraction: Securely hook and hoist the failed 8 HP submersible grinder pump out of the wet well vault. Waste Disposal: Safely transport and dispose of the failed pump and old contaminated fittings according to local environmental regulations. Phase 3: New Pump Installation & Wiring Equipment Inspection: Uncrate and verify physical and electrical specs of the new 7.5 HP / 8 HP, 460V, 3-Phase commercial submersible grinder pump. Lowering & Seating: Lower the new pump into the wet well basin using heavy-duty lifting chains . Properly seat and align the pump base on the basin floor or existing slide-flange guide rail system. Electrical Integration: Route the new heavy-duty power cords to the exterior control panel. Splice and secure all wire leads. Verify proper three-phase motor rotation (clockwise impellor movement) to prevent dry-spin damage. Phase 4: Plumbing Modification & Main Line Tie-In Piping Buildout: Fabricate a new 2-inch Schedule 80 heavy-wall discharge assembly off the pump discharge nozzle. Valve Installation: Inline-mount one (1) new 2-inch cast iron full-flow swing check valve to prevent system backflow, followed by one ( 1 ) 2- inch heavy-duty brass isolation ball valve for future maintenance shutdowns. Infrastructure Adaptation: Mount a 6-inch by 2-inch mechanical concentric reducer fitting (heavy-duty shielded elastomeric or cast iron no-hub coupling). Final Connection: Tie the new 2-inch valve assembly securely into the City of Kalamazoo's 6-inch cast iron infrastructure main line, setting all mechanical joint bands to standard commercial torque specifications. Phase 5: Commissioning & System Testing Static Leak Test: Introduce fluid into the system to verify pressure seals and check for leaks across all new joints and valves. Operational Testing: Restore full system power. Conduct manual and automatic drawdown tests using the existing float switches to verify correct start/stop sequences and amp draws under load. Site Cleanup: Remove all tools, rigging equipment, and consumables from the site, returning the lift station perimeter to a clean, safe state Bidders shall address questions regarding the specifications to Quentin Pike, Citywide Facilities ManagerPublic Works Division at pikeq@kalamazoocity.org.
