Tunnel 9 Pitch Upgrade

The Arnold Engineering Development Complex (AEDC) Tunnel 9 in Silver Spring, Maryland, requires the comprehensive modernization of a high-performance hydraulic motion system. This Firm-Fixed-Price (FFP) requirement, designated as a total Small Business Set Aside under NAICS 332912, encompasses the design, engineering, procurement, off-site fabrication, pre-assembly, on-site demolition, installation, and commissioning of core system components. Key deliverables include a primary control valve with a step response time of 55 ms or less, a main actuating cylinder with a 120.5 inch working stroke capable of 13 ft/s linear speed, a Hydraulic Power Unit (HPU), and a dedicated filtration and cooling kidney loop. All components must adhere to ASME B31.1, ASME BPVC VIII, and ISO 4406 standards. The project is structured in three phases: engineering and design, manufacturing and testing, and disassembly, installation, and start-up. The delivery schedule for the primary requirement is 46 weeks from the lead time event. Award will be based on a combination of technical capability, evaluated on an acceptable/unacceptable basis via a Contractor Statement of Work, past performance on similar hydraulic systems, and price reasonableness. Contractors must comply with strict Department of Defense marking and reporting requirements, including MIL-STD-130 for unique item identification and the use of the Wide Area WorkFlow (WAWF) system for invoicing. Additionally, offerors must meet specific Cybersecurity Maturity Model Certification (CMMC) level requirements and provide a CMMC UID in their proposal.
