• Question 2: Clarification on the distance between the ATLAS system and the cross-hatched area. The actual distance is 36", and this area is depicted as an example egress pathway that cannot be blocked by open doors, per the RFQ requirements.

• The due date for proposals remains April 15, 2026, at 5:00 PM Mountain Time.

• Bidders are reminded to submit proposals electronically to Maurice.Nelson@nlr.gov.

• Companies submitting proposals should include confirmation of receipt and acceptance of this amendment in their cover letter.

Form / Attachment / Pricing Sheet

This document outlines specific vendor and installation requirements for the opportunity. It details criteria related to vendor experience, after-sales service, demonstrated capability, and physical installation constraints.

• Vendor Experience & Proven Installations: Requires offerors to have manufactured, delivered, and installed a minimum of five (5) units of comparable equipment within the past five (5) years for research laboratories, universities, or equivalent institutions. Evidence must include customer details, contact information, and installation summaries. NLR reserves the right to independently verify installations.
• After-Sales Service & Lifecycle Support: Requires a written warranty with specified coverage terms, duration, and guaranteed response times for on-site service. Offerors must also document the availability of replacement parts and trained personnel for at least seven (7) years post-delivery.
• Demonstrated Capability Requirement: NLR may require a demonstration of previously delivered comparable equipment in operation prior to award.
• Installation Location and Utility Requirements:
  • Physical Space & Location Constraints: Specifies restrictions for pathing to the installation location, including fitting through an 8' wide by 10' tall roll-up loading dock door and navigating a hallway with overhead obstacles at 9' above floor level. The fully assembled tool must fit within a defined cross-hatched area. Egress requirements mandate a ≥36" wide path, and equipment access/maintenance panels must not obstruct this path. A minimum of 28" clearance is required for maintenance access. Final tool height is restricted to 12' high within 3' of facility walls, but can be up to 18'11” high elsewhere.
  • Utility Constraints: Sets limits on electrical power consumption (<160 kW), chamber cooling water energy requirement (<239,000 btu/h or 70 KW with a 16 deg F ∆T), and heat dissipation to ambient air (<12,000 btu/h). Offerors must provide expected water temperature rise and CHW flow, and the amount of heat dissipated into the lab space. Note: LN2 is not available for chamber cooling.

This attachment is critical for bidders to understand the specific experience, support capabilities, and logistical/utility requirements for installation. Failure to meet these requirements can lead to removal from technical consideration or impact proposal feasibility. Bidders must carefully review the physical space constraints, including dimensions and egress paths, as well as the utility limitations, and confirm their proposed equipment can meet these specifications.

Amendment / Modification

This amendment addresses questions received regarding the Request for Quote (RFQ) for the Level 3 Environmental Chamber. The questions and answers provided clarify various aspects of the chamber's requirements and the procurement process. Key clarifications include:

• Racking System: Vendors are to specify the distance required between modules for adequate airflow.
• Water Inlet: A 3/4" FNPT inlet is required, placed on the ceiling or side of the chamber toward the rear.
• Access Ports: Four ports for access wires are preferred at a height between 5'-6' from the floor, positioned roughly 1/3 and 2/3 front to back.
• Live Load: Solar panels may be energized during testing, contributing to the "live load." The specific heat dissipation for this live load is detailed in the specification levels.
• Walk-in Chamber Dimensions: While NREL estimates dimensions of 150" High X 171" Long X 150" Wide, building entryways are constrained to 117" tall by 90" wide.
• Lead Time: Estimated lead time for award can vary based on technical evaluation, terms negotiation, and safety document review.
• Humidity Control: The RH setpoint during water spray will be around 95+/- 5% RH, with typical temperatures of 25°C or 40°C. Needed set points for humidity control include 85°C/85%RH, 60°C/95%RH, and 60°C/10%RH, with an air dryer requested.
• Codes and Standards: Evaluating against UL508A, NFPA 70, and UL61010-1 is acceptable; field evaluations are also acceptable.
• Floor Drain: A trench 4' x 2" is needed, feeding at least a 1/4" drain, with a flow of up to 2.1 gpm.
• Test Article Temperature Uniformity: For dead load situations, uniformity must be within ±2°C. For live load situations, uniformity deviation may exceed approximately 10°C, and overshooting chamber air temperature to achieve ramp rates is acceptable, with specifications applying to test article temperature.
• Price Justification: Offerors are preferred to provide at least 3 redacted invoices for similar systems billed within the last 18 months.
• SAM.gov Registration: Offerors must be fully registered and active in SAM.gov.

This amendment primarily consists of Questions & Answers that clarify existing requirements and do not appear to introduce new sections or modify existing ones directly, but rather provide further detail and context.

The proposal due date remains August 8, 2025, at 5:00 PM Mountain Time. Offerors are reminded to submit proposals electronically to Nicole.Edun@nrel.gov and to include confirmation of receipt and acceptance of this Amendment in their cover letter. No changes to evaluation criteria or submission rules are indicated beyond the need to acknowledge this amendment.
