Summary

This is a pre-qualification bid document and contract drawings from the City of Philadelphia Water Department for the replacement of switchgear and motor control centers (MCCs) at the Northeast Water Pollution Control Plant. The project involves the replacement of electrical equipment serving the sludge digestion and gas facilities, including new 480V switchgear (SDT-1), four new motor control centers (MCC SDT-1, MCC SDT-2, MCC SDT-3, and MCC SGF-1), two new oil-filled transformers (T-13A-3 and T-13B-3), a new 48VDC power system with battery chargers, and new variable frequency drives (VFDs) for sludge gas compressors. The comprehensive contract drawings include 16 sheets detailing one-line diagrams, elevations, schematic diagrams, control circuits, and site plans. All work must be performed in strict compliance with applicable city, state, and national regulations including OSHA requirements, the National Electric Code, BOCA Building Code, and NFPA standards. The contractor is responsible for providing all necessary safety equipment, removing obsolete equipment, minimizing service interruptions, and coordinating construction sequencing to maintain proper plant operation.

The estimated contract value is between $3,000,000 and $4,000,000. This solicitation is for pre-qualification only, with approved sellers to receive notice and invitation to a subsequent closed bid solicitation. The project is managed by the City of Philadelphia Water Department's Planning & Engineering Division, with design work completed by I. Baba and R. Jacobs as of March 11, 2026. The contract drawings specify detailed electrical specifications, including conduit sizing, grounding requirements, conductor specifications, junction box sizing, and equipment clearances. The contractor must provide temporary power to feeders during switchgear removal and replacement and install future infrastructure components, including four-inch GRS conduits to a basement pullbox for a planned future screening project.
