The existing HPA system has insufficient capacity to meet current and future testing demands, and its storage vessels are nearing the end of their service life. This project seeks to address these shortfalls by replacing existing storage vessels to extend the system's life and installing new storage vessels to increase overall HPA capacity. 3. Project Objectives & Definition of Success

Definition of Prototype Success

Operational Utility Operational utility, within the Department of War, refers to the degree to which a system, weapon, technology, capability, or process contributes to the successful completion of military missions and objectives within the operational environment. It encompasses mission effectiveness, integration, logistics, cost effectiveness, and adaptability. A successful prototype project will be one that delivers a fully operational, integrated, and sustainable system(s). The primary objective is to deliver two new, independent, and fully functional HPA storage systems at AEDC. The scope includes all engineering, design, analysis, procurement, demolition of specified legacy components, fabrication, installation, inspection, and testing required for the systems. The new installations are expected to be generally consistent in form and function with the existing test facility installation (see Appendix F for reference), with the scaling as noted in the requirements documents. The solution must be installed at the specific locations identified in Appendix E and integrated with existing infrastructure at the designated tie-in points. 4. Key Performance Parameters The proposed prototype must satisfy, at a minimum, the following critical performance parameters (details may be found in the Performance Parameters and Appendices):

Storage Capacity

Each location shall provide the following storage volumes:

Location 1

27,000 ft3 ( 5%)

Location 2

6,800 ft3 ( 5%)

Operating Pressure

The HPA distribution system must be designed for a pressure of no less than 4,400 PSIG.

Pressure Loss

The system shall induce no more than 50 PSID of pressure loss from any bottle's discharge to the connection point with the existing HPA distribution system.

System Integration

The solution must seamlessly connect to the existing HPA distribution system at the headers specified in Appendix E (NPS 4 for Location 1 and NPS 18 for Location 2). Connections must feature double-block-and-bleed valve protection.

Summary (Newest Update)

Background The United States Air Force, through the Air Force Test Center (AFTC) at Arnold AFB, TN, is seeking innovative solutions for the High Pressure Air Storage Expansion (HPASE) project. This initiative aims to enhance the capacity and longevity of the existing High Pressure Air (HPA) system at the Arnold Engineering Development Complex (AEDC), which is critical for testing activities. The current HPA system is insufficient to meet future demands, and its storage vessels are nearing the end of their service life. The project will involve design, fabrication, installation, and commissioning of new HPA storage systems. Work Details The contract involves delivering two independent and fully functional HPA storage systems at AEDC. Key requirements include: - **Storage Capacity**: - Location 1: 27,000 ft³ (±5%) - Location 2: 6,800 ft³ (±5%) - **Operating Pressure**: Minimum of 4,400 PSIG. - **Pressure Loss**: No more than 50 PSID from discharge to connection point with existing HPA distribution system. - **System Integration**: Must connect seamlessly with existing infrastructure at specified tie-in points with double-block-and-bleed valve protection. - **Control System Compatibility**: Must use Emerson RX3i PLCs and Proficy Machine Edition 9.5 for PLC software and Cimplicity 9.5 for HMI interface. **Vessel Requirements**: - Fabrication must be integrally forged, single-wall construction per ASME BPVC Section VIII, Div. 1; layered vessels are not acceptable. - Material must be Low Alloy Steel, ASME SA-372, Grade L. - Design life must be at least 40 years with specified fatigue cycles. Period of Performance The geographic location(s) the product will be delivered to or performed at. Place of Performance Arnold AFB, TN. Bidder Requirements Offerors must meet NIST SP 800-171 and CMMC Level 2 certification requirements. Interested parties should contact the Agreements Officer with their company's CAGE code for access to protected requirement documents. Incumbent Analysis (see Incumbents section for more detail) This opportunity appears to have a confirmed incumbent based on prior Air Force Test Center/AEDC awards to Healtheon for the High Pressure Air Additional Capacity (HPAAC) programs, including HPAAC Phase II (FA910122DB001-FA910124FB001, $44,677,895, 10/25/23–12/30/26) and the earlier HPAAC effort (FA910116D0009-FA910120F0039, $23,881,335, 06/22/20–03/31/24). The current HPASE requirement similarly focuses on expanding and sustaining AEDC’s high pressure air storage capability by designing/fabricating/installing new HPA storage systems and integrating them with existing infrastructure and controls. The “expansion/additional capacity” framing and emphasis on new storage vessels suggest continuity with the prior HPAAC work rather than a wholly unrelated utility upgrade.
