About this file
These reference sketches detail a comprehensive HVAC and electrical system replacement project for Building 104 at Torii Station, Fort Buckner, Okinawa, Japan. The project involves removing existing deteriorated HVAC systems and installing new infrastructure, including multiple types of air conditioning units: single package rooftop A/C units, ceiling-suspended split A/C systems, wall-mounted split A/C units, and roof ventilators. The scope also includes electrical upgrades such as new disconnect switches (NEMA4X, stainless steel, weatherproof), a new lightning protection system, and associated concrete pad and support systems.
The project addresses critical infrastructure concerns, particularly potential equipment damage from existing system leaks. The renovation includes removing asbestos and lead-containing materials, constructing new concrete pads, installing motor dampers, and implementing a phased approach with multiple installation stages. The project is part of a pre-solicitation for the U.S. Air Force Pacific Forces, with the solicitation number JOL02339, and is currently awaiting fund availability. The design and construction must comply with specified technical requirements and safety standards for facility equipment protection.
