About this file
This is a Statement of Work (SOW) for the replacement of a sewer pump controller and annual preventive maintenance services at Adams National Park in Quincy, Massachusetts. The project consists of three main components: (1) a fixed-price line item for removing and replacing the failed sewer pump controller at 181 Adams Street with a new controller and floats that restores automatic operation and integrates with the existing pump system; and (2) and (3) two time-and-materials line items for comprehensive annual preventive maintenance at both 181 and 135 Adams Street, including lift station tank cleaning, pump and valve inspection, electrical panel verification, and alarm testing. The existing equipment to be replaced is a KCP-3TV Duplex Control Panel (208/230/460V, 3-Phase) with GSE20NO Roto-Float switches, which has experienced motherboard failure with a currently disconnected alarm sensor.
The contractor must comply with NEC (NFPA 70), OSHA confined space entry standards, and local codes, and must provide a Job Hazard Analysis and Confined Space Entry Permit prior to work. Key deliverables include product data sheets, schematics, as-built drawings, test reports, maintenance checklists, and warranty certificates. Work is scheduled Monday through Friday, 7:00 AM to 3:00 PM, with a one-year parts and labor warranty on the controller and components plus a one-year workmanship warranty including a 90-day follow-up inspection. The SOW explicitly excludes pump, valve, or major piping replacement beyond minor repairs, environmental remediation, and work outside normal business hours. All systems must be tested and commissioned with staff training provided prior to project closeout.

Scope of Work Project: Replace Sewer Pump Controller and Perform Annual Tank Maintenance Location: Adams National Park, 181&135 Adams Street, Quincy, MA 02169
1) Project Overview & Objectives Base FFP Line — 181 Adams St. – Pump Controller Replacement: Safely remove the existing sewer pump controller and furnish/install a new controller and floats that restores reliable automatic operation, protects pumps, and integrates with existing pump system.
T&M Line 1 — 181 Adams St. Annual Maintenance: Perform a comprehensive annual preventative maintenance service on the lift station, interior tank cleaning, associated pumps, valves, level-sensing devices, wiring, and panels to reduce failure risk and verify system performance.
T&M Line 2 — 135 Adams St. Annual Maintenance: Perform a comprehensive annual preventative maintenance service on the lift station, interior tank cleaning, associated pumps, valves, level-sensing devices, wiring, and panels to reduce failure risk and verify system performance.
Outcome: A fully functional, tested, and documented system with clear maintenance records and recommendations.
2) Existing Conditions (Contractor to Verify) lift station sizes and depth, influent loads, and accessibility.
Quantity and type of pumps (e.g., submersible sewage pumps), nameplate data, and control float switches.
Current controller brand/model, enclosure rating (NEMA), breaker and starter arrangement, and alarm interface local horn/strobe.
Available power (voltage/phase), panel condition, conduit/cable routing, and grounding.
Confined space classification, gas hazards, ventilation, and retrieval equipment.
Bypass/overflow provisions and site-specific emergency response procedures.
3) Technical Requirements
3.1 Supply & Install new Controller and floats. Same or equal to existing: Features include Lead/Lag logic, HOA selectors, alarms, NEMA 4X enclosures, proper power components, elapsed time meters, documentation, sequencing, and compatibility.
3.2 Annual Maintenance: Includes pump chamber pressure wash cleaning, pump inspection, valve checks, electrical panel inspection, alarm testing, functional testing, float replacement as needed and reporting.
4) Codes, Standards & Safety Comply with NEC (NFPA 70), OSHA confined space standards, and local codes.
Follow lockout/tagout (LOTO), arc-flash PPE, and spill containment best practices.
Provide Job Hazard Analysis (JHA) and Confined Space Entry Permit.
5) Submittals & Deliverables Pre-Work: Product data sheets, schematics, JHA, work schedule.
Post-Work: As-built drawings, configuration backup, test reports, maintenance checklist, warranty certificates.
6) Execution Mobilization & Pre-Start, Demolition/Removal, Installation, Programming & Calibration, Testing & Commissioning, Training, Closeout.
7) Schedule & Work Hours Work Hours: Monday – Friday 7:00 – 3:00.
Milestones: Submittal approval → Equipment receipt → Install → Commission → Training → Closeout.
8) Warranty & Support Controller & components: Minimum 1-year parts/labor.
Workmanship: 1-year warranty on installation quality.
Include one follow-up check within 90 days.
9) Acceptance Criteria All alarms and control modes function per sequence; lead/lag alternation verified.
Pump performance within nameplate current and expected cycle frequency.
Level sensors calibrated; alarm notifications confirmed locally and remotely.
Deliverables received and accepted; staff trained; site restored.
10) Exclusions Replacement of pumps, valves, or major piping beyond minor repairs.
Environmental remediation beyond normal waste handling.
Notes Notes: 181 Adams St. sewer pump controller replacement due to a failed motherboard. Alarm sensor currently jumped out.
