The U.S. Army Corps of Engineers, Japan District (USACE-POJ), is conducting a market survey for the P530 Aircraft Intermediate Maintenance Facility project at Kadena Air Base, Okinawa, Japan. This Design-Bid-Build (DBB) construction project, estimated between $25,000,000 and $100,000,000, involves building an intermediate maintenance facility for the Aircraft Intermediate Maintenance Detachment (AIMD). The survey aims to identify local sources—firms physically located, licensed, and registered to conduct business in Japan—to assist the Government's acquisition planning. Only local sources will be considered for the corresponding solicitation, which is anticipated to be an Invitation for Bids (IFB) in the 3rd Quarter FY26, with an estimated performance period of 800 calendar days. Interested firms must be registered in the SAM database and possess necessary construction licenses from the Government of Japan. Responses to the market survey are due by January 15, 2026, Japan Standard Time, and can be submitted via an online form or emailed to the contracting officers.

Benchmark information, including elevations and coordinates, is provided for key reference points. The demolition plans specify items to be removed, including curb/curb & gutter, storm structures and sewers, light poles, underground electric, protective pillars, and fences, with instructions for protection of remaining utilities and structures. All dimensions are in metric units, and surveys were conducted in 2023 and 2024 using the Japan Geodetic Datum (JGD) 2011, Zone 15. The project aims to modernize the facility by detailing necessary demolition and site preparation for future construction, emphasizing protection of existing infrastructure.

This document outlines structural specifications for the P530 Aircraft Intermediate Maintenance Facility project at Kadena AFB, Okinawa, Japan, for the US Army Corps of Engineers. It details standards for concrete and steel reinforcement, including hook schedules, development and lap splice lengths based on bar size and concrete compressive strength, and material properties for reinforcing steel. The file also covers general structural notes for cast-in-place concrete, such as minimum compressive strengths for various applications, concrete cover requirements, and guidelines for construction joints, embedded conduits, and housekeeping pads. Additionally, it specifies structural steel fabrication and erection in accordance with AISC standards, material properties for different steel shapes and bolts, and requirements for post-installed anchors and dowels, including testing, installation, and inspection protocols. Verification and inspection requirements are listed for steel, concrete, soils, and pile foundations, categorizing them as continuous or periodic to ensure compliance and structural integrity.

This document, part of a federal government RFP (Contract No. W912HV19D0012) for the US Army Corps of Engineers, Japan District, details the mechanical, HVAC, and piping plans for the P530 Aircraft Intermediate Maintenance Facility at COMFLEACT Okinawa JA Kadena AFB, Okinawa, Japan. The 65% design submittal, issued July 2025 by WOOLPERT, Inc., includes extensive diagrams and notes for the first and second floors and roof. Key elements cover HVAC control diagrams, double-wall insulated spiral ductwork for exposed round ducts, and HVAC zoning plans with wall-mounted sensors. Piping plans specify chilled water and HVAC control system diagrams, pipe sizes, hydronic accessories, and system components. Sections illustrate AHU-1, AHU-2, AHU-3, and DOAS-1 installations, including condensate drain routing, equipment support pads, air separators, and chilled water pipe routing. Comprehensive mechanical details are provided for VAV terminal units, air device runouts, diffuser installations, inline centrifugal fans, AHU/DOAS P-trap drains, cooling coil piping, piping wall penetrations, and equipment labeling. Furthermore, the document outlines detailed pipe hanger and support specifications, including spacing, rod diameters, and material requirements for various pipe types, with explicit notes on installation, seismic restraints, and insulation protection.

The document outlines the control points and operational sequences for the P530 Aircraft Intermediate Maintenance Facility's HVAC systems at Kadena AFB, Okinawa, Japan. It details the Chiller Control, Chilled Water Plant Control, Dedicated Outside Air System (DOAS-1), Air Handling Units (AHU-1, AHU-2, AHU-3), and Variable Air Volume (VAV) terminal units. Key functions include chiller status, compressor operation, evaporator and condenser controls, chilled water temperature management, and various alarms for critical conditions like low temperature cutouts and pressure failures. The document also specifies control modes (local/remote), runtime hours, and various temperature and pressure points for monitoring. The DOAS-1 operates supply fans continuously in occupied mode and intermittently in unoccupied mode based on humidity, with chilled water and electric reheat coils maintaining discharge set-points. Filter monitoring and smoke detection are crucial safety features. AHU-1/AHU-2/AHU-3 supply fans modulate based on VAV terminal unit airflow requirements, with critical zone static pressure and supply air temperature reset controls. Miscellaneous diagrams detail AC units, various exhaust fans (inline, upblast, downblast), and emergency shutdown procedures. The contractor is responsible for completing the points schedule according to specifications and instructions, ensuring proper integration and alarming for all systems. The overall purpose is to provide a comprehensive framework for the control and alarming of the facility's complex HVAC infrastructure.
