STATEMENT OF WORK (SOW)

FI-MUE Gaum RHN X-Band AC Replacement

78th Signal Battalion

1. INTRODUCTION

This Statement of Work (SOW) defines the requirements, scope, responsibiliƟes, and deliverables for the turnkey replacement of two (2) 10-ton packaged Air CondiƟoning (AC) units that provide mission-criƟcal cooling for the Naval Computer and TelecommunicaƟons StaƟon (NCTS) / Regional Hub Node (RHN)

Guam X-Band Terminal.

2. SCOPE OF WORK

The contractor shall provide all necessary project management, materials, equipment, labor, and technical services to perform the following:

2.1. Decommissioning and Removal of ExisƟng AC Units

Perform lock-out/tag-out (LOTO) and safely disconnect both legacy AC units from the electrical distribuƟon system.

In accordance with all environmental regulaƟons, recover and reclaim all refrigerant from both units.

Drain and contain all compressor oils and other lubricants for proper disposal.

Rigorously disconnect and remove the units from their roof curbs/mounƟng pads.

Dismantle and transport the legacy AC units from the site to an authorized disposal and recycling facility.

Remove and dispose of any associated conduits, refrigerant lines, or ductwork that cannot be reused for the new system installaƟon.

2.2. Disposal and Environmental Compliance

The contractor is solely responsible for the off-base transportaƟon and final disposal of the two decommissioned AC units, including all components, refrigerants, and oils.

All hazardous materials must be handled and disposed of in strict compliance with U.S.

Environmental ProtecƟon Agency (EPA) and applicable local Guam environmental regulaƟons.

The contractor shall provide the ContracƟng Officer's RepresentaƟve (COR) with official receipts and cerƟficates of disposal/destrucƟon for all hazardous materials and decommissioned equipment as a condiƟon of project acceptance.

2.3. InstallaƟon of New Packaged AC Units

Prepare the site for installaƟon, including any necessary modificaƟons to the exisƟng mounƟng pads to accommodate the new units.

Coordinate the delivery, rigging, and offloading of the two new packaged AC units.

Install and securely anchor both units in their designated posiƟons.

Perform electrical integraƟon to the exisƟng power panel. The contractor may reuse exisƟng conduits and wiring, provided they are in serviceable condiƟon, appropriately sized per the new equipment specificaƟons, and can be connected without splicing. If exisƟng wiring is inadequate, the contractor shall provide and install new wiring from the panel to the units.

Connect to exisƟng ductwork. If modificaƟons are required, they shall be executed to Sheet

Metal and Air CondiƟoning Contractors' NaƟonal AssociaƟon (SMACNA) standards.

Install new refrigerant lines, ensuring they are correctly sized, insulated, and pressure-tested per manufacturer specificaƟons.

2.4. TesƟng and Commissioning

The contractor shall develop and submit a comprehensive Test and Commissioning Plan to the technical POC for review and approval no later than 14 days prior to scheduled tesƟng.

Verify all electrical connecƟons, safeƟes, and control sequences.

Conduct funcƟonal performance tesƟng, which must include, at a minimum: verificaƟon of refrigerant charge, measurement of airflow (CFM), temperature differenƟals across coils, and staƟc pressures.

Demonstrate the system's ability to meet the cooling load requirements as specified.

Coordinate any required power outages with the COR at least 30 business days in advance.

2.5. Handover and DocumentaƟon

Provide on-site training for facility personnel covering the operaƟon, rouƟne maintenance, and troubleshooƟng of the new HVAC system.

Submit a final documentaƟon package containing as-built drawings, manufacturer's installaƟon and operaƟon manuals, a complete startup/commissioning report, and all warranty documents.

Conduct a final project walkthrough with the COR for official handover and acceptance.
