Army Contracting Command – Red River Army Depot (ACC-RRAD) Organic Industrial Base (OIB) Modernization Commercial Solutions Opening (CSO)

Solicitation # W911RQ-26-S-C001

The U.S. Army, through the Army Contracting Command – Red River Army Depot, is pursuing the modernization of its Organic Industrial Base under Commercial Solutions Opening W911RQ-26-S-C001, a flexible procurement initiative authorized under DFARS Subpart 212.70 and administered under FAR Part 12 Commercial Item Procedures. This effort is aligned with the Army’s strategic focus on Convergent Manufacturing, integrating advanced technologies such as digital twin, automation, connected digital enterprise, and cybersecurity to enhance producibility, sustainment, and logistics capabilities. The solicitation invites innovative commercial solutions across multiple areas of interest including automated media blast systems, camera monitoring for vehicle test tracks, power pack interface and test sets, AS9100 certification support, track pin and bushing manufacturing, and fixture removal for Bradley Fighting Vehicle hulls. Each area of interest is evaluated independently with specific submission deadlines, and all responses must be submitted electronically via email in two separate volumes: a technical proposal excluding cost data and a price proposal with full cost breakdowns, including labor rates, material quotes, and overhead. Offers must be unclassified, submitted through SAM.gov-registered entities with a Unique Entity ID, and adhere to strict formatting rules including a maximum of five pages or fifteen slides for initial solution briefs. Evaluation of proposals prioritizes technical merit and feasibility, followed by industrial base impact, speed and scalability of implementation, price fairness and reasonableness, private investment leverage, and a credible transition plan to full production. The government will use a trade-off approach rather than lowest price technically acceptable, with no numerical weights assigned but clear emphasis on non-price factors. Awards are contingent upon funding availability, successful negotiation, and technical validation, and do not obligate the government to proceed with any contract until formal award. Performance is expected to occur at Red River Army Depot in Texarkana, Texas, with inspection and acceptance conducted by the government at that location per MIL-DTL-11891, MIL-STD-1907, ASTM, and other referenced standards covering material quality, inspection, and manufacturing processes. Contractors must register in Wide Area Work Flow for invoicing, and proposals must comply with secure-by-design principles and modular open systems architecture requirements.

Full Description

Reissue of Solicitation of Offers. This solicitation of offers cancels and supersedes previous solicitation of offers number 5000088650 dated November 4, 2025 with a closing of December 4, 2025 at 2:00 PM. Canada is seeking offers from qualified Offerors to provide professional services to deliver the “Enhanced understanding of fluidelastic instability (FEI) in nuclear steam generators, specifically in the streamwise (in-line) direction, to ensure the long-term reliability and structural integrity of tube arrays under two-phase flow conditions” study to Canadian Nuclear Safety Commission. The scope of this study includes the following three interrelated components: • Establishing a test setup to facilitate observation and assessment of local void fraction behavior and flow-induced responses in tube arrays representative of CANDU steam generators. The setup is based on established configurations and industry knowledge, with the goal of supporting technical evaluation under controlled two-phase flow conditions. • Execution of flow assessments using multiple test sections with representative pitch ratios. Tests are conducted across a range of flow conditions (approximately 50 to 500 kg/m²·s mass flux) to capture relevant stability behavior under typical operating parameters. • Data collection and technical analysis to generate a structured dataset that can support future studies and inform regulatory assessments. The results contribute to an improved understanding of how tube arrays respond under various conditions, particularly regarding the onset and behavior of streamwise fluidelastic effects.
