Statement of Work (SOW) Replacement of Pier Waterline Shore Connection for Berths 1, 2 and 3 on Coast Guard Island, Alameda, CA

1. Introduction/Background

The existing potable water shore connection assembly at the pier has reached the end of its serviceable life, exhibiting signs of severe corrosion, leakage, or mechanical failure. A complete replacement is required to ensure a safe, reliable, and sanitary water supply for Coast Guard operations.

2. Objective

The objective of this project is to remove the existing, degraded waterline shore connection on the pier and install a new, fully operational, and compliant potable water shore connection. This infrastructure supports direct water transfer to moored vessels and must withstand the marine environment.

3. Scope of Work

The Contractor shall provide all labor, materials, equipment, supervision, and quality control necessary to execute the replacement of six (6) potable water shore connections. There are two double connection systems at each of the three cutter berths at the pier (see attached photo). Contractor is responsible for removing and replacing everything downstream of the designated tie in connection, conducting appropriate sanitation and testing per industry standards and certifying all new backflow preventers. Contractor is responsible for verifying all measurements and dimensions onsite.

3.1. Demolition and Removal

3.1.1. Isolate and secure the existing water supply line at the nearest upstream shut-off valve. Ensure Coast Guard POC is notified.

3.1.2. Disconnect and remove the existing shore connection assembly, including valves, flanges, meters, backflow preventers, and associated piping up to the pipe flanges supplying the service vaults which will be the designated tie-in points (see attached photo).

3.1.3. Properly dispose of all removed materials off-site in accordance with local and environmental regulations.

3.2. Installation of New Shore Connection

3.2.1. Inspect the existing tie-in point for integrity and prepare the surface/flange for the new connection.

3.2.2. Install new piping, fittings, and isolation valves from the tie-in point to the new shore connection.

3.2.3. Install a new marine-grade, reduced pressure zone (RPZ) backflow prevention assembly.

3.2.4. Install a new potable water meter (if present to facility specifications).

3.2.5. Install the final shore connection point (e.g., cam-lock fitting, flanged connection, or standard threaded fire hose connection as specified by the facility), ensuring it is compatible with vessel intake fittings.

3.2.6. Apply marine-grade protective coatings to all exposed, non-stainless metal surfaces to prevent corrosion.

3.2.7. Install appropriate pipe supports, hangers, or brackets to secure the new assembly to the pier structure, accounting for vibration and tidal movements if applicable.

3.3. Testing and Commissioning

3.3.1. Perform hydrostatic pressure testing of the newly installed assembly to 150% of the maximum operating pressure for a minimum of two hours to ensure zero leakage.

3.3.2. Flush the new system with potable water to remove any debris or contaminants.

3.3.3. Disinfect the new assembly in accordance with AWWA (American

Water Works Association) standards for potable water systems.

3.3.4. Conduct bacteriological testing; the system shall not be placed into service until a negative/passing test result is achieved.

3.3.5. Certify each newly installed backflow preventer.

3.3.6. Function-test all valves and backflow preventer.

4. Material Requirements

4.1. Piping and Fittings: All materials must be certified for potable water use.

High-Density Polyethylene (HOPE), Type 316 Stainless Steel, or approved marine-grade ductile iron are preferred to resist saltwater corrosion.

4.2. Valves: Bronze or stainless-steel body, suited for marine environments.

4.3. Backflow Preventer: ASSE-approved, marine-environment suitable Reduced

Pressure Zone (RPZ) assembly.

4.4. Hardware: All bolts, nuts, and mounting hardware shall be Type 316

Stainless Steel.

5. Safety and Environmental Compliance

5.1. Environmental: The Contractor shall ensure no construction debris, tools, or hazardous materials (e.g., pipe joint compound, paint) are dropped into the water. A spill containment kit shall always be on-site.

5.2. Hot Work: If welding or cutting is required, a Hot Work permit must be obtained from the Facility Safety Officer or Fire Marshal.

5.3. Water outages: Prior to taking any water source offline contractor is requested to get permission via the Coast Guard POC at least 72 hours in advance.

6. Deliverables

6.1. Schedule: Contractor shall provide the Coast Guard a written schedule before being granted notice to proceed. The work shall be phased so that only one berth is taken down at a time. Work shall be phased to minimize down time of each cutter berth. The contractor shall work with the Coast Guard POC to determine best phase of work to least interrupt cutter schedule.

6.2. Closeout: Hydrostatic test reports, bacteriological water test results, backflow preventer certification, and as-built drawings or updated schematics of the new connection.

7. Period of Performance

7.1. All work shall be completed within 120 days of award.

7.2. Contractor may only take one berth down at a time.

8. Laydown and Material Storage

The Coast Guard POC will coordinate an appropriate amount of storage space as necessary for equipment and material storage during the project. The contractor is responsible for maintaining the security of this space and their equipment. This space shall be always kept tidy.

9. Codes and Standards

9.1. All work shall comply with the most current editions of all applicable federal, state, and local codes, all applicable industry standards, and the following USCG-specific standards:

9.1.1. U.S. Coast Guard Safety and Environmental Health Manual, COMDTINST M5100.47 (series).

9.1.2. OSHA Regulations

9.1.3. American Water Works Association (AWWA) Standards for potable water connections.

10. Personnel Security and Base Access

10.1. Access Request: For access to the USCG facility, the contractor is required to submit the name and birthdate for each employee on the approved access request form at least 72 hours before their first day on site (this form will be provided after awarded). Personnel not listed may be denied access to the Coast Guard facility.

10.2. Identification: A Real ID-compliant driver's license, or other federally approved identification is required for base access. Acceptable forms of ID include US Government Dependent ID, Federal PIV Card, TWIC Card, Veterans Health Identification Card, US Passport or Permanent Resident Card. Driver's licenses from states that are not Real ID compliant will not be accepted.

10.3. Vehicle Requirements: All contractor vehicles must have valid registration and insurance, and all vehicle operators must have a valid driver's license.

The contractor shall provide and use ground fault circuit interrupter (GFCI) devises when connecting to Government power sources.

14. Acceptance Criteria

Final acceptance of the work will be granted by the USCG COR after final inspection confirms that all tasks in this WOE have been completed, the installation meets all technical and safety standards, and the sire has been fully restored. Final payment will not be released until all deficient items have been corrected.
