Statement of Work: DDPM252018_B1677 Replace Altitude Valve

Statement of Work

Location: 136th Airlift Wing, Naval Air Station Joint Reserve Base, Fort Worth, TX 76127 Date: 17 June 2025

Project: Building 1677 Replace Altitude Valve Project Number: DDPM252018

1. Background:

1.1. Building 1677 was constructed in 1999 and serves as the 136th Airlift Wing Fire Suppression Pump House. The existing Altitude Valve, which is critical to maintain a specific water level in an elevated storage tank, is inoperable, thus requiring recurrent manual filling of the water storage tank.

2. Scope of Work and Objectives:

2.1. Overall Objective: The Contractor shall provide all labor, supervision, equipment, tools, materials, transportation, and incidentals necessary to furnish and install a fully functional replacement altitude valve on the existing underground fire suppression line to the fire protection storage tank located within Building 1677, the 136th Airlift Wing Fire Suppression Pump House. The objective is to restore the proper operation and reliability of the fire suppression system, ensuring adequate water pressure and level control within the storage tank to meet the fire protection needs of the 136th Airlift Wing complex and hangars. The Contractor shall ensure a fully functional and compliant altitude valve for the existing fire suppression system upon completion of this project.

2.2. Compliance and Approvals: All work must be performed in accordance with this statement of work (SOW), applicable specifications, drawings, and applicable federal, state, and local building codes, as well as Unified Facilities Criteria (UFC) and Unified Facilities Guide Specifications (UFGS).

3. Tasks: The Contractor shall perform the following:

3.1. Pre-Work Verification and Responsibility: The Contractor is encouraged to field verify all existing conditions, dimensions, and system configurations prior to submitting a bid. This includes, but is not limited to:

3.1.1. Altitude Valve Inspection: Inspect and document the size, connection type (flanged, threaded, etc.), and condition of the existing altitude valve, and any other pertinent information in accordance with industry standards. Determine the valve's operating pressure range and flow capacity.

3.1.2. Piping System Assessment: Verify the material, size, and condition of the existing underground piping connected to the altitude valve. Identify any signs of corrosion, leaks, or damage.

3.1.3. Control System Interface: Determine how the altitude valve interacts with the overall fire suppression system control panel and any associated sensors or monitoring devices. Verify compatibility of the replacement valve with the existing control system.

3.1.4. Power Requirements: Determine the voltage and amperage requirements for the replacement valve, if applicable.

3.1.5. Applicable Codes and Standards: Verify all applicable federal, state, and local building codes, as well as Unified Facilities Criteria (UFC), National Fire Protection Association (NFPA) standards (specifically NFPA 13 and NFPA 25), and any other relevant regulations that govern the installation and operation of fire suppression systems.

3.2. System Isolation and Shutdown: Safely isolate the affected portion of the fire suppression system to allow for valve replacement. Implement appropriate lockout/tagout procedures. The Contractor shall coordinate all shutdowns with the 136th CES to minimize disruption to operations.

3.3. Altitude Valve Removal and Disposal: Remove the existing altitude valve from the piping system. Dispose of the removed valve in accordance with all applicable environmental regulations.

3.4. Altitude Valve Installation: Install a new altitude valve that meets or exceeds the performance specifications of the existing valve listed in section four of this document. Ensure proper alignment, connection, and sealing to prevent leaks.

3.5. Control System Integration: Integrate the new altitude valve with the existing fire suppression system control panel. Configure the control system to properly monitor and control the valve's operation. Verify compatibility with the existing system.

3.6. System Startup and Testing: Repressurize the fire suppression system and test the operation of the new altitude valve. Verify that the valve maintains the proper water level in the storage tank and that all associated auto operation systems are functional. Conduct flow tests to verify adequate water supply.

3.7. Documentation and Training: Provide all required documentation, including system test certificates, as-built drawings, and operation and maintenance manuals. Provide training to designated 136th AW personnel on the operation and maintenance of the new altitude valve and associated systems.

4. Existing System Information. The following information regarding the existing fire suppression systems is provided for informational purposes only and does not constitute a complete or guaranteed representation of the existing conditions. The Contractor shall verify the accuracy and completeness of this information and fully identify all existing components, equipment, and conditions necessary for the successful completion of this project.

4.1. Existing Fire Suppression System Configuration: The existing fire suppression system employs a 400,000-gallon ground-level water storage tank as its primary water source. Protection is provided to two aircraft hangars and approximately eight other facilities via a network of fire suppression piping. System pressure is maintained at 120 psi by an electric jockey pump. In the event of a fire and subsequent pressure drop within the system, the following pumps are activated sequentially based on decreasing pressure thresholds:

4.1.1. Electric Pump 1: 2500 GPM @ 100 psi

4.1.2. Electric Pump 2: @ 80 psi

4.1.3. Diesel Pump: @ 55 psi

4.2. The water tank is intended to be automatically replenished via an altitude control valve installed within an underground vault. The altitude control valve modulates based on tank water level/pressure to maintain adequate water supply by drawing from the commercial water supply. The existing altitude control is located in a 8” pipe, and is currently inoperable.

4.2.1. The metal plate on the altitude valve is faded but is interpreted to the best of Governments ability to read:

4.2.1.1. Size & Cat No. - 8 / 210-01AB

4.2.1.2. Stock No. - 210-01-215J

4.2.1.3. Code: PR
