Only those prime contract offerors who formally registered, attended, and signed the official government attendance log during that specific site visit are eligible to submit a proposal in response to this solicitation. The Government will cross-reference all incoming proposals against the official site visit registration log immediately upon the closing of the response window. Proposals received from any vendor who did not attend the mandatory site visit will be deemed administratively non-responsive and will be excluded from the competitive range. Non-attending vendor proposals will not be evaluated by the Technical Evaluation Panel (TEP) or considered for award. L.2 Incorporation of FAR 52.212-1 and Tailoring Pursuant to FAR 12.301, the provision at FAR 52.212-1 is incorporated directly into this solicitation by reference. The terms of this provision apply to all aspects of this Request for Proposal (RFP). Offerors are explicitly instructed to separate their proposal submissions into three distinct, independent volumes: Volume I (Technical Proposal and Salient Characteristics Cross-Reference Addendum), Volume II (Past Performance References), and Volume III (Business, Price Proposal, and Signed Certifications). L.3 Brand Name or Equal Notice (FAR 52.211-6) The Government intends to acquire a 7T MRI System utilizing a "Brand Name or Equal" description. The Siemens MAGNETOM Terra.X Impulse Edition establishes the baseline standard of quality and performance required by the National Institutes of Health (NIH). Proposals offering "Equal" items from alternative manufacturers will be fully considered for award. To be eligible for award, alternative systems must meet or exceed every technical metric and operational requirement defined in the Minimum Salient Characteristics in Section C. If the offeror proposes an alternative "equal" system, they must include a standalone technical section in their proposal titled "Volume I: Addendum . Technical Equivalence Demonstration." Within this addendum, the offeror must itemize formal engineering spec sheets and a line-by-line cross-reference matrix proving equivalence. Vague or conversational statements without verifiable technical metrics will result in a pass/fail rejection of the technical proposal during initial screening. L.4 Small Business Subcontracting Plan Instruction In accordance with FAR 52.219-9, other-than-small-business (large business) offerors must submit a formal Small Business Subcontracting Plan with their proposal. This requirement does not apply to small business concerns. If the offeror represents itself as a small business under the designated NAICS code 334510 for this procurement, no subcontracting plan is required. Other-than-small-business offerors must establish realistic, positive subcontracting goals. While the core 7T MRI hardware manufacturing may be performed in-house by the prime contractor, offerors are expected to identify commercial subcontracting opportunities within the ancillary turn-key services, specifically targeting specialized mechanical installation, campus transit, and mobile crane rigging logistics (CLIN 0003). Failure to submit an acceptable Small Business Subcontracting Plan with the proposal will render the offeror ineligible for contract award. L.5 Trade Agreements Certification Requirement The Offeror shall complete and submit FAR 52.225-6 (Trade Agreements Certificate) with its business/price proposal. Failure to return the completed certificate or certifying an end product from a non-designated country shall render the proposal ineligible for award. Contractor representations and certifications are verified electronically using active records in SAM.gov pursuant to FAR 12.205(a). L.6 System for Award Management (SAM) Registration Requirements Pursuant to FAR 52.204-7, incorporated by reference, offerors must be actively registered in SAM.gov at the time of proposal submission and at the time of contract award. In accordance with updated procurement guidelines, a temporary administrative lapse during the evaluation phase will not automatically disqualify an offeror, provided active status is fully restored prior to the final award determination. Offerors shall maintain their profile in accordance with FAR 52.04-13 post-award. L.7 Certification of Exemption from the Service Contract Labor Standards (FAR 52.222-48) The Offeror shall complete and submit the certification at FAR 52.222-48. By signing the proposal, the Offeror certifies that the specialized medical equipment, installation calibration mechanics, and lifecycle service agreements meet all commerciality criteria under FAR 22.1003-4(c), exempting this procurement from the Service Contract Labor Standards. L.8 Electronic and Information Technology Accessibility Requirements Pursuant to HHSAR 352.239-73 (DEVIATION), the Offeror shall submit a completed Accessibility Conformance Report (ACR) for all user-facing software, console systems, and digital interfaces integrated into the 7T MRI system. The ACR must be generated using the Voluntary Product Accessibility Template (VPAT) Version 2.4 (or later) Section 508 Edition. Failure to provide an ACR documenting compliance with the applicable Revised 508 Standards shall render the proposal technically unacceptable. L.9 Past Performance Volume Submission Requirements Offerors shall submit a maximum of three (3) past performance references for contracts executed or completed within the past five (5) years from the issuance date of this solicitation. To be deemed "relevant" to this procurement, references must demonstrate successful delivery, calibration, and field-ramping of an active 7-Tesla (7T) or higher human MRI system, or turn-key physical installations involving specialized heavy-tonnage rigging, crane maneuvers, and facility engineering integrations under contracts exceeding $5,000,000. If the offeror intends to utilize a specialized third-party sub-contractor to execute the CLIN 0003 Turn-Key Rigging and Mechanical Installation Services, the offeror must submit at least one (1) past performance reference specifically validating that rigging subcontractor's successful completion of a high-tonnage medical equipment lift within a tight urban or campus envelope. Section M: Evaluation Factors for Award M.1 Initial Administrative Responsiveness Screening & Site Visit Gating Prior to conducting a qualitative technical evaluation under Section M.4, the Contracting Officer will perform an initial administrative review of all proposals. A primary element of this screening is verifying attendance at the mandatory site visit. If an offeror failed to register, attend, and sign the official attendance log during the mandatory site visit, their proposal will be rejected as administratively non-responsive and will be excluded from the competitive range. Non-attending vendor proposals will not receive a qualitative technical rating (Outstanding down to Unacceptable) or be considered for award. M.2 Basis for Award - Best Value Tradeoff - Award will be made to that responsible offeror whose proposal provides the combination of features that offers the best or greatest overall value to the Government. The Government is more concerned with obtaining performance capability superiority rather than lowest overall cost. However, the Government will not make an award at a significantly higher overall cost to the Government to achieve only slightly superior performance. Overall cost to the Government may become the ultimate determining factor for award of a contract as proposals become more equal based on the non-price technical factors. M.3 Subcontracting Plan and Compliance Review - Prior to contract award, the Contracting Officer will review the Small Business Subcontracting Plan submitted by the apparent successful large business offeror for acceptability in accordance with FAR 19.705-4. An offeror will be deemed ineligible for contract award if they fail to negotiate a subcontracting plan that is acceptable to the Contracting Officer M.4 Non-Price Technical Evaluation Factors - SEE ATTACHMENT

Section L: Instructions to Offerors L.1 Mandatory Site Visit Attendance and Proposal Eligibility Gating Rule A mandatory site visit was officially conducted and concluded on September 3, 2026,at the NIH Bethesda facility. Only those prime contract offerors who formally registered, attended, and signed the official government attendance log during that specific site visit are eligible to submit a proposal in response to this solicitation. The Government will cross-reference all incoming proposals against the official site visit registration log immediately upon the closing of the response window. Proposals received from any vendor who did not attend the mandatory site visit will be deemed administratively non-responsive and will be excluded from the competitive range. Non-attending vendor proposals will not be evaluated by the Technical Evaluation Panel (TEP) or considered for award. L.2 Incorporation of FAR 52.212-1 and Tailoring Pursuant to FAR 12.301, the provision at FAR 52.212-1 is incorporated directly into this solicitation by reference. The terms of this provision apply to all aspects of this Request for Proposal (RFP). Offerors are explicitly instructed to separate their proposal submissions into three distinct, independent volumes: Volume I (Technical Proposal and Salient Characteristics Cross-Reference Addendum), Volume II (Past Performance References), and Volume III (Business, Price Proposal, and Signed Certifications). L.3 Brand Name or Equal Notice (FAR 52.211-6) The Government intends to acquire a 7T MRI System utilizing a "Brand Name or Equal" description. The Siemens MAGNETOM Terra.X Impulse Edition establishes the baseline standard of quality and performance required by the National Institutes of Health (NIH). Proposals offering "Equal" items from alternative manufacturers will be fully considered for award. To be eligible for award, alternative systems must meet or exceed every technical metric and operational requirement defined in the Minimum Salient Characteristics in Section C. If the offeror proposes an alternative "equal" system, they must include a standalone technical section in their proposal titled "Volume I: Addendum . Technical Equivalence Demonstration." Within this addendum, the offeror must itemize formal engineering spec sheets and a line-by-line cross-reference matrix proving equivalence. Vague or conversational statements without verifiable technical metrics will result in a pass/fail rejection of the technical proposal during initial screening. L.4 Small Business Subcontracting Plan Instruction In accordance with FAR 52.219-9, other-than-small-business (large business) offerors must submit a formal Small Business Subcontracting Plan with their proposal. This requirement does not apply to small business concerns. If the offeror represents itself as a small business under the designated NAICS code 334510 for this procurement, no subcontracting plan is required. Other-than-small-business offerors must establish realistic, positive subcontracting goals. While the core 7T MRI hardware manufacturing may be performed in-house by the prime contractor, offerors are expected to identify commercial subcontracting opportunities within the ancillary turn-key services, specifically targeting specialized mechanical installation, campus transit, and mobile crane rigging logistics (CLIN 0003). Failure to submit an acceptable Small Business Subcontracting Plan with the proposal will render the offeror ineligible for contract award. L.5 Trade Agreements Certification Requirement The Offeror shall complete and submit FAR 52.225-6 (Trade Agreements Certificate) with its business/price proposal. Failure to return the completed certificate or certifying an end product from a non-designated country shall render the proposal ineligible for award. Contractor representations and certifications are verified electronically using active records in SAM.gov pursuant to FAR 12.205(a). L.6 System for Award Management (SAM) Registration Requirements Pursuant to FAR 52.204-7, incorporated by reference, offerors must be actively registered in SAM.gov at the time of proposal submission and at the time of contract award. In accordance with updated procurement guidelines, a temporary administrative lapse during the evaluation phase will not automatically disqualify an offeror, provided active status is fully restored prior to the final award determination. Offerors shall maintain their profile in accordance with FAR 52.04-13 post-award. L.7 Certification of Exemption from the Service Contract Labor Standards (FAR 52.222-48) The Offeror shall complete and submit the certification at FAR 52.222-48. By signing the proposal, the Offeror certifies that the specialized medical equipment, installation calibration mechanics, and lifecycle service agreements meet all commerciality criteria under FAR 22.1003-4(c), exempting this procurement from the Service Contract Labor Standards. L.8 Electronic and Information Technology Accessibility Requirements Pursuant to HHSAR 352.239-73 (DEVIATION), the Offeror shall submit a completed Accessibility Conformance Report (ACR) for all user-facing software, console systems, and digital interfaces integrated into the 7T MRI system. The ACR must be generated using the Voluntary Product Accessibility Template (VPAT) Version 2.4 (or later) Section 508 Edition. Failure to provide an ACR documenting compliance with the applicable Revised 508 Standards shall render the proposal technically unacceptable. L.9 Past Performance Volume Submission Requirements Offerors shall submit a maximum of three (3) past performance references for contracts executed or completed within the past five (5) years from the issuance date of this solicitation. To be deemed "relevant" to this procurement, references must demonstrate successful delivery, calibration, and field-ramping of an active 7-Tesla (7T) or higher human MRI system, or turn-key physical installations involving specialized heavy-tonnage rigging, crane maneuvers, and facility engineering integrations under contracts exceeding $5,000,000. If the offeror intends to utilize a specialized third-party sub-contractor to execute the CLIN 0003 Turn-Key Rigging and Mechanical Installation Services, the offeror must submit at least one (1) past performance reference specifically validating that rigging subcontractor's successful completion of a high-tonnage medical equipment lift within a tight urban or campus envelope. Section M: Evaluation Factors for Award M.1 Initial Administrative Responsiveness Screening & Site Visit Gating Prior to conducting a qualitative technical evaluation under Section M.4, the Contracting Officer will perform an initial administrative review of all proposals. A primary element of this screening is verifying attendance at the mandatory site visit. If an offeror failed to register, attend, and sign the official attendance log during the mandatory site visit, their proposal will be rejected as administratively non-responsive and will be excluded from the competitive range. Non-attending vendor proposals will not receive a qualitative technical rating (Outstanding down to Unacceptable) or be considered for award. M.2 Basis for Award - Best Value Tradeoff - Award will be made to that responsible offeror whose proposal provides the combination of features that offers the best or greatest overall value to the Government. The Government is more concerned with obtaining performance capability superiority rather than lowest overall cost. However, the Government will not make an award at a significantly higher overall cost to the Government to achieve only slightly superior performance. Overall cost to the Government may become the ultimate determining factor for award of a contract as proposals become more equal based on the non-price technical factors. M.3 Subcontracting Plan and Compliance Review - Prior to contract award, the Contracting Officer will review the Small Business Subcontracting Plan submitted by the apparent successful large business offeror for acceptability in accordance with FAR 19.705-4. An offeror will be deemed ineligible for contract award if they fail to negotiate a subcontracting plan that is acceptable to the Contracting Officer M.4 Non-Price Technical Evaluation Factors - SEE ATTACHMENT
