Project 3. DRAFT SOW LXEZ201076 Repair Water Mains_Phase II_edited2_Redacted.pdf

This Statement of Work (SOW) details a design-build project for repairing water lines at Kadena Air Base in Okinawa, Japan, with a total project duration of 841 calendar days. The project primarily focuses on rerouting and replacing existing water mains located underneath the airfield runways, which are over 60 years old and prone to leakage and ruptures. Key objectives include installing 16-inch and 12-inch water mains along a new route within the runway right-of-way, eliminating distribution mains running through flightlines, and ensuring compliance with Unified Facilities Criteria (UFC) and National Fire Protection Association (NFPA) requirements.

The project scope encompasses comprehensive activities including field investigations, design, plant labor, supervision, materials, equipment, transportation, and construction work. Specific technical requirements include geotechnical investigations, cultural and UXO surveys, temporary erosion control, installing new water main connections, providing pressure reducing valves, upgrading firefighting flows, and ensuring environmental compliance. The work will be executed in multiple phases with distinct design and construction periods, including 271 days for design, 540 days for construction, and 30 days for administration, with a total project budget implied to be between $10-50 million based on the related industry engagement event description.
