NASA Goddard released the HBG II final RFP, 80GSFC27R0015, on October 21, 2026. The official notice covers scientific research for the Earth Sciences Division’s HBG laboratories and Terrestrial Information Systems Laboratory. It describes a small-business acquisition and a hybrid IDIQ with both cost-plus-fixed-fee (CPFF) and firm-fixed-price (FFP) task orders over a five-year ordering period. The original offer deadline is December 4, 2026 at 2:00 p.m. EST, subject to amendments.
Final RFP and amendment update, checked November 6, 2026: stage, deadline, small-business acquisition and hybrid contract structure were verified from the official final notice. Detailed final solicitation attachments have not yet been fully reviewed. Do not rely on earlier draft limits, evaluation weights, ceiling, submission instructions or phase-in assumptions as final requirements. The final solicitation and amendments control.

| Competition / size standard | The final notice description states a small-business set-aside. Confirm the applicable size standard, eligibility and representations in the final solicitation. |
| NAICS / PSC | NAICS 541715 — Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology). PSC AJ11. |
| Value / minimum | Not yet verified against the final solicitation package. Do not carry forward the April 2025 draft ceiling or minimum as final terms, award value or guaranteed revenue. |
| Final-notice contract structure | Hybrid IDIQ with both cost-plus-fixed-fee (CPFF) and firm-fixed-price (FFP) task orders and a five-year effective ordering period from the contract effective date. Award count, phase-in details and other terms require final-package review. |
| Place of performance | Earlier draft background: Goddard Space Flight Center, Greenbelt, Maryland, and contractor facilities. Final performance locations have not yet been verified against the final package. |
| Proposal volumes | Final volume structure has not yet been verified. Build the compliance matrix from the final solicitation rather than relying on the earlier draft volumes. |
| Page limits | Final page limits and exclusions have not yet been verified. Use the released solicitation and amendments, not the April 2025 draft limits. |
| Evaluation | Final evaluation factors, relative importance and scoring have not yet been verified. Do not carry forward the draft factor ordering or point weights without checking the final package. |

Background
The requirement supports Cryospheric Sciences, Ocean Ecology, Hydrological Sciences, Biospheric Sciences, Geodesy and Geophysics, and Terrestrial Information Systems. Research areas span water resources, ecosystems, sea-level change, snow and ice, natural hazards and geodesy.
For capture teams, the differentiator is the connection between scientific excellence and reliable delivery: maintaining data continuity, integrating specialist teams, managing task orders and pricing the workforce credibly. Confirm how the final evaluation treats these capabilities before assigning proposal emphasis.
GDI Capture Take: Pursue with Conditions. Prime with a credible integrated team, accounting readiness, realistic staffing economics and relevant evidence. If capabilities are concentrated in one specialty, consider a teammate role rather than overstating prime readiness. This is GDI’s planning assessment, not an agency evaluation decision.
Requirements
The following are GDI proposal-readiness questions and planning guidance, not verified final requirements or evaluation criteria. Build the compliance matrix from the released final solicitation and amendments.
01 Science, Data & Mission Support
Map the final statement of work to responsible team members and evidence. Check the required science, computing, instrument, data-service and field-support tasks against the released package rather than assuming the draft scope is unchanged.
02 Management & Workforce Continuity
How will the team demonstrate program-manager authority, cross-laboratory coordination, recruitment and retention, subcontractor integration and repeatable task-order execution? Confirm the final management evaluation, staffing requirements and phase-in duration; do not use draft scoring or timing assumptions.
03 Cost Realism & Accounting Readiness
Reconcile the pricing approach and delivery responsibilities with the final notice’s hybrid CPFF and FFP task-order structure. Align labor rates, staffing commitments, bases of estimate and technical resources. Verify accounting-system requirements and the final cost evaluation before relying on draft provisions.
04 Teaming & Prime Readiness
A qualified small-business prime needs an integrated delivery model across the required science and support areas. Specialist firms may be better positioned as teammates. Resolve gaps in scientific disciplines, scientific computing, calibration and field operations with accountable roles. Evaluate joint-venture arrangements and subcontracting limitations against final requirements.
05 Past Performance & Relevance
Which references best demonstrate the team’s relevant performance? Check the final recency, relevance, reference, subcontractor and evaluation rules before selecting examples. Earlier draft thresholds, weighting and definitions have not been verified as final.
06 Compliance & Submission
Build the L/M compliance matrix from the final package. Confirm required volumes, file formats, page limits, upload destination, contacts and advance-notice steps. The original offer deadline is December 4, 2026 at 2:00 p.m. EST, subject to amendments. Verify OCI, export-control, access and IT-security obligations without assuming a clearance or certification requirement.
