The Naval Surface Warfare Center, Dahlgren Division (NSWCDD) has issued a Statement of Work (SOW) for the procurement of an Electromagnetic Interference (EMI) Shielded Chamber to enhance its electromagnetic compatibility (EMC) and EMI testing capabilities. The requirement includes the supply and installation of a shielded chamber, with specified dimensions of 27’x 16’x 12’, equipped with essential features such as low-EMI LED lighting, multiple shielded doors, and specific power filter cabinets. Additionally, there are optional components including a shielded ante-room and fire-retardant RF absorbers, which must meet defined reflectivity standards. The contractor is responsible for all labor and material installation, adhering to OSHA regulations and CDC guidelines. The room must be installed onsite in Dahlgren, Virginia, with no government-furnished materials, except for prepared space and electricity at the site. The contract stipulates that the work must be conducted during regular hours and coordinated with a technical point of contact. The document highlights the unclassified nature of the work and outlines travel regulations in compliance with federal standards. This SOW showcases the government's commitment to advancing safety and effectiveness in military testing environments.

The document addresses the requirements for an anechoic chamber within a government proposal context. It clarifies the difference between RF absorption and RF attenuation, emphasizing that while RF absorption focuses on minimizing reflections for accurate testing, RF attenuation pertains to the chamber's ability to shield against external electromagnetic interference. The critical question raised is whether there are specific RF attenuation requirements included in the specifications. In response, it is confirmed that the chamber must achieve an attenuation of approximately 100 decibels (dB) against external emissions within the frequency range of 80 MHz to 18 GHz. Furthermore, with operational internal systems, the ambient electromagnetic level in the chamber should be at least 6 dB below the limits specified in MIL-STD-461G, ensuring compliance with military standards. This detailed information is essential for guiding the design, pricing, and scheduling of the project, reinforcing the importance of clarity in federal RFP specifications.

The document is a Request for Proposal (RFP) from the Naval Surface Warfare Center Dahlgren Division (NSWCDD) seeking contractors to provide an Electromagnetic Interference (EMI) Shielded Chamber and associated services. The primary objectives include the procurement of a shielded chamber, installation preparations, and potential optional items such as a shielded ante-room and RF absorbers, all aimed at facilitating electromagnetic compatibility testing. Key components required are detailed specifications of the chamber dimensions, power filter cabinets, and safety compliance according to OSHA and CDC guidelines. The proposal outlines delivery schedules, acceptance criteria, and payment procedures, including provisions for small business participation. Submission of proposals is due by May 5, 2025, with overarching legal and procedural terms incorporated via FAR clauses. The document emphasizes the government’s focus on ensuring regulatory compliance, safety, and quality in supporting military capabilities through advanced testing environments.
