This amendment modifies attachments related to evaluation instructions and pricing, which may impact proposal preparation and submission requirements. Bidders should review the updated and newly added attachments carefully.

Form / Attachment / Pricing Sheet

This document is Attachment C, a Pricing Sheet for RFQ No. 80JSC026Q0001. It is to be completed by the Offeror to provide pricing details for the services requested.

• CLINs (Contract Line Item Numbers): Includes Base Year (CLIN 1), Option Year 1 (CLIN 2), Option Year 2 (CLIN 3), and a 6-month extension under clause 52.217-8 (Option to Extend Services).
• Pricing Fields: Offerors must fill in 'List Price' and 'AMOUNT' for each CLIN and the 'TOTAL FIRM FIXED PRICE'.
• Company Information: Fields for 'Company Name', 'Quote No.', and 'Date' are to be filled out by the Offeror.
• Quote Validity: Quotes must be valid for a minimum of 90 days from submission.

This pricing sheet is critical for bidders to calculate and submit their proposed costs for the opportunity. It outlines the structure for pricing the base period, option years, and the potential 6-month extension. The rates used in the last Option Year will be applied to the 6-month extension as per the solicitation's reference to clause 52.217-8.

Solicitation / RFP / RFQ

This document outlines the evaluation instructions and criteria for the "80JSC026Q0001" solicitation, specifically for Attachment B, Revision 1, dated 12/15/2025. It details the two-step evaluation process bidders must undergo.

• Step One (1) – Meeting Key RFQ Requirements: Bidders must answer two specific Yes/No questions regarding the quote being for a commercial-off-the-shelf (COTS) Decompression Sickness Data Modeling System and not containing sustaining licensing fees beyond the period of performance. Failure to answer "Yes" to both will result in elimination.

• Step Two (2) – Trade-Off: This step involves evaluating proposals based on three factors in descending order of importance: Technical Acceptability, Past Performance, and Price.

• The document references a potential five-year period of performance for pricing evaluation.

• Technical Acceptability: Evaluated by experts for scientific and technical merit, relevance to RFQ objectives, and ability to develop an operationally-relevant product. Rated as Outstanding, Acceptable, or Unacceptable. Consistency with proposed price is also assessed.

• Past Performance: Rated as Acceptable, Neutral, or Unacceptable. References from up to three customers with similar projects are required, along with documentation of team qualifications. The government may also use CPARS, SAM.gov, or other sources.

• Price: Evaluated for reasonableness, unbalanced pricing, and completeness. The Total Evaluated Price (TEP) and detailed pricing sheet will be used. Option period pricing will be evaluated but does not obligate the government to exercise options.

• Deadlines: Quotes must be valid for a minimum of 90 days from submission. Specific submission deadlines are not detailed in this attachment but are implied by the "period of performance" and "time of submission."

Not specified in this document.

• This document is Revision 1 of Attachment B, dated 12/15/2025.
• Bidders must submit one price quotation using the template provided in Attachment C – Pricing Sheet, with a detailed breakout by base and option years.

Statement of Work (SOW) / Performance Work Statement (PWS)

To develop a model that accurately predicts Spaceflight Decompression Sickness (DCS) risk, based on research and operational data, for use as an operationally-feasible, mission-relevant risk prediction tool for lunar and Mars exploration. NASA will retain ownership of the data and rights to the developed model.

• Develop a model to predict the risk of Type I and Type II DCS, considering factors such as cabin/spacesuit pressures, sex, cardiorespiratory fitness, body composition, hydration, diet, ambulation during EVA, temperature, and prebreathe protocols.

• The model must be compliant with NASA-STD-7009 (NASA-STD-7009B-Final-3-5-2024.pdf).

• Quantify confidence and uncertainty of risk predictions for key crew subgroups and mission-relevant conditions.

• Utilize a NASA-provided training dataset (~1500 trials) and potentially supplement with publicly-available or other datasets.

• NASA will hold a subset of the dataset for model validation.

• Prediction accuracy and precision will be assessed by NASA statistical and modeling experts.

• The model development is to be completed within an 8-month period.

• The model will be used for lunar and Martian surface operations.

• Deliverables include a compiled and executable DCS prediction tool with source code, a real-time validation tool, and a final report detailing methods, results, limitations, and recommendations.

• The contractor must provide a user guide and describe all datasets used.

• A publication plan and copies of peer-reviewed publications are required, if applicable.

• Proposers may incorporate datasets from their institution, provided they are not already within the NASA dataset and are described in detail.
