Subject: Statement of Work Project Name: Leak Detection of Pools.

IJO#: CC-24209-4J

Project Location: 727 – Cadet Pool / 700B - Therapy Pool Project Description: Locate Leaks Date: 25 February 2025

Scope:

The intent of this scope of work to describe the labor and materials necessary to perform the leak detection methods to find the areas leaking in the Cadet Pool and Therapy Pool. Between both pools West Point is losing about 50K gallons a day. Pool Service Technician conduct an underwater inspection and leak detection of the pool system to locate any leaks and identify any failed concealed pipes responsible for water loss less evaporation.

Work Requirements:

Leak detection methods to be used:

*Filter equipment and concealed pipes will be isolated from the pool and balance tank by many temporary plugs so this portion can be checked for loss independently.

*Balance tank will be isolated from the pool and filter system by temporary plugs so this portion can be checked for loss independently.

*Pool will be isolated from the filter equipment and balance tank by temporary plugs so this portion can be checked for loss independently.

*Underwater surfaces will be checked for the acoustic signatures of leaks and flows with an underwater microphone, particularly around 52 penetrations and many linear feet of discolored areas.

*Underwater surfaces of the pool and balance tank will receive an up‐close visual inspection by diving in them and documenting voids and defects. Suspect areas will receive a dye test that makes a flow of water visible.

*Penetrations in the pool and balance tank will be checked for leakage and defects by up‐close visual inspection and either dye test or flow test with a cofferdam.

*Concealed pipes below the surface, including the bottom drain pipe, will be tested by isolating with test plugs and making a very low pressure non‐destructive test by detecting any flow from the vessel into the pipe.

*Underwater lights and the niche in the pool wall containing them will be tested for any loss by isolating with a cofferdam and detecting any pressure differential caused by escaping water.

*Leaks will be documented as to type, location, and approximate rate of loss by written description and underwater photographs.

NOT IN THIS SCOPE:

*Repair of leaks is not included in this scope.

*If a loss is detected in a concealed pipe, the accessible pipe ends will be identified, but additional work with other specialized equipment to locate and document break(s) and hole(s) along the length of the concealed pipe is not in this scope.

Coordination required:

*Water temperature 80 degrees or above at the start of each day.

*De‐energize pool systems when requested and throughout most of the time onsite.

*Restrict access to the pool room, both for the safety of others, and to lessen noise that can interfere with the work.

*It may be necessary to briefly stop some building systems that transmit sound and vibration through the structure during the acoustic portion of the testing.

*Access to one electrical receptacle within 100 feet of the balance tank hatch.

*Access to a standard garden hose fitting within 100 feet of pool.

*Access to a bathroom. Shower and changing area is appreciated but not required.

*Parking for 1 SUV‐style vehicle near the entrance.

*Three days onsite, between 7 and 10 hours duration. (727 - Cadet Pool)

*One day onsite, between 7 and 10 hours duration. (700B – Therapy Pool)

*One additional day (each location) onsite held in reserve for hidden issues and complications.

*Written report issued within five business days later.

Working Hours:

The contractor shall perform these services 8 hours a day, until completion of work, Monday through Friday, (excluding Federal Holidays). Exceptions to this policy for the request of overtime must be coordinated through the COR and the Contracting Officer.
