About this file
This is a Scope of Work (SOW) for the replacement and rehabilitation of a sewage lift station at U.S. Coast Guard Station Cape Charles, Virginia. The work encompasses all labor, materials, equipment, and supervision necessary to restore the system to efficient and fully functioning condition, with a lump-sum pricing structure required from the contractor.
The project requires contractors to establish a temporary bypass pumping system prior to commencing work, with approval from the Contracting Officer's Representative (COR). Primary demolition and site preparation tasks include disconnection and removal of existing sewage pumps, controls, level sensors, alarms, piping, and manhole steps; removal of sludge from the vault; remediation of loose or deteriorated concrete; and proper off-site disposal of all debris in compliance with local, state, and federal regulations. Electrical work involves removal of existing wiring and installation of new 3-phase 208 VAC wiring rated for wet and corrosive environments, a new NEMA 4X duplex pump control panel, an intrinsic safety barrier, and a new alarm system with audible and visual indicators for high water level, pump failure, and loss of power. Mechanical and structural requirements include rehabilitation of the manhole with a corrosion-resistant watertight lining system (minimum 30-year manufacturer lifetime), installation of two submersible non-clog sewage grinder pumps with guide rail systems, new interior piping with check and isolation valves, a new ventilation system with odor control filter, and a new level control system for pump operation and alarm activation.
Contractor personnel must possess a minimum of 10 years' experience in similar systems and provide proof of comparable projects. The period of performance cannot exceed 120 calendar days from issuance of the Notice to Proceed, with work performed during normal operational hours (0800-1600, Monday-Friday) unless COR-approved. Submittals must be provided within 30 days of Notice to Proceed and include work schedules, O&M manuals, product datasheets, and shop drawings. Upon completion, the contractor must conduct operational testing demonstrating proper pump function in lead, lag, and alternating sequences; provide minimum four hours of training to Coast Guard personnel; and deliver as-built drawings and two complete sets of O&M manuals. The COR has 10 business days to review deliverables, with the contractor having 10 business days to make corrections if needed.
