The Naval Surface Warfare Center, Dahlgren Division (NSWCDD) has issued Solicitation N0017825RC613, an RFP for an Electromagnetic Interference (EMI) Shielded Chamber and related components. The solicitation, issued on April 4, 2025, with an offer due date of August 20, 2025, at 12:00 PM, is a total small business set-aside under NAICS 332313. The requirement includes a 27’x16’x12’ EMI shielded chamber (CLIN 0001), a 10’x8’x8’ shielded ante-room (CLIN 0002), RF absorber material for the chamber (CLIN 0003), installation services (CLIN 0004), and shipping (CLIN 0005). The contractor is responsible for furnishing and installing all items, adhering to OSHA and CDC guidelines, and protecting government property. Delivery of the EMI shielded chamber is required within 30 weeks After Date of Contract (ADC), while the ante-room and RF absorber are due within 90 days ADC. Installation and shipping are scheduled for 40 weeks ADC. Invoicing will be processed through the Wide Area WorkFlow (WAWF) system, and specific clauses regarding commercial supplier agreements, data rights, and small business utilization are incorporated.

This amendment to solicitation N0017825RC613, modification 0002, reissues a revised Statement of Work (SOW) to clarify specifications for each Contract Line Item Number (CLIN) and extends the proposal submission deadline to August 20, 2025. The Naval Surface Warfare Center, Dahlgren Division (NSWCDD) requires an Electromagnetic Interference (EMI) Shielded Chamber for electromagnetic emissions and susceptibility testing. The SOW details requirements for an EMI Shielded Chamber (CLIN 0001), a shielded Ante-room (CLIN 0002), and fire-retardant RF Absorber (CLIN 0003), including specific dimensions, components, and performance criteria. The contractor is responsible for installation, providing a material list, adhering to safety regulations (OSHA, CDC), protecting government property, and working during specified hours. Travel is required and will be reimbursed per Federal Travel Regulations. The amendment also changes the option status for CLINs 0002 and 0003 to 'No Status' and deletes certain clauses while incorporating others by reference.

This government file, likely an addendum to an RFP, clarifies requirements for two attenuation enclosures (CLIN 0001 and CLIN 0002). Key clarifications include confirmation that neither CLIN requires anechoic properties, no floor filler tiles are needed, and no acoustic requirements like silencers are necessary. The project timeline estimates one week for design review followed by construction. On-site conditions confirm lay down space and the need for special badging for crew. The interior finish for both units will be sheet metal panels. Structural requirements specify a concrete board base for moisture protection and anchoring the chamber frame to the concrete floor. The contractor is responsible for providing brass nipples for power filter mounting and RF testing. The project does not require the contractor to hook up electrical, provide bolted unistrut, include a door maintenance kit, or provide fiber penetrations.

This government file addresses facility and installation questions for an EM Chamber project at NSWC Dahlgren. The facility's largest opening is 10'x10', allowing for some pre-assembly of the 27'x16'x12' EM Chamber and its 10'x8'x8' Ante Room. The contractor (CTR) is responsible for providing and installing power filters and pass-through couplers, but not the internal electrical distribution system (panel boards, transformers, breakers). The local team will handle short power and wiring connections to the filters. For anchoring, the concrete board under the chamber will float, while the steel support structure will be anchored to the host concrete floor using heavy-duty wedge-style anchors. A 1/4" concrete board layer will act as a protective barrier between the chamber floor and the finished concrete. This clarifies the scope of work regarding facility constraints, electrical responsibilities, and chamber anchoring for potential vendors.

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 outlines specifications and requirements for two line items, CLIN 0001 and CLIN 0002, related to the construction of sound attenuation enclosures. Both items require a 100 dB attenuation enclosure without anechoic properties and should feature a sheet metal panel finish. Design approval is expected within one week, followed by construction, while the site has sufficient laydown space and necessitates crew badging. The contractor must install a concrete board base for moisture protection and should ensure the enclosure's structural integrity with proper anchoring. Notably, there are no acoustic requirements, chilled water penetrations, or electrical hookups needed, although the contractor must provide RF testing. Additional equipment, such as brass nipples for power filter mounting, should be included, while several maintenance and interior installation options were declined. This project appears to be part of federal contracting efforts, focusing on technical specifications to meet government standards efficiently and effectively while adhering to safety regulations and construction guidelines.

The document addresses technical inquiries regarding the installation of Electromagnetic (EM) Chambers at the NSWC Dahlgren facility. It confirms that the facility has limitations with bay door dimensions (10'x10'), affecting the assembly of the larger EM Chamber (27x16x12) and the optional Ante Room (10x8x8) on-site. It clarifies that the contractor is responsible for providing Power Filters and necessary components for installation but is not required to supply the electrical distribution system; local teams will handle all electrical wiring and connections post-installation. Additionally, the document outlines how the EM Chamber's floor should be anchored to the finished concrete floor using concrete anchors, ensuring proper support. The proposed method includes a protective layer of concrete board under the chamber floor for safeguarding and the use of heavy-duty wedge-type anchors for stability. The document serves to clarify technical specifications and responsibilities within the context of the RFP process, facilitating clear communication between the government and the contractor.
