Addendum #1 

YAKUTAT TLINGIT TRIBE

REQUEST FOR PROPOSALS (RFP) PROFESSIONAL ENGINEERING, ENVIRONMENTAL, AND TECHNICAL SERVICES

Addendum #1

Indefinite Delivery / Indefinite Quantity (IDIQ) Single Award Task Order Contract (SATOC)

August 14th, 2026

1. The previous submission deadline of August 24th, 2026 is extended three days to August 27th, 2026.
2. Regarding Native/Tribal owned scoring, does it require the prime to be Native/Tribal owned, or can subs contribute to this score?

YTT will provide AN/AI scoring based upon the participation of both the prime and subs at their discretion - the intent is for proposing firms to be actively performing meaningful portions of the work. The intent is not for AN/AI qualifying firms to apply as prime applicants for the purposes of scoring preference points.

1. Could you provide a brief description of Project 2 – Ankau Culvert Replacements?

Tasks 1–6 already describe the project scope. No additional narrative is able to be provided at this time.

1. Will Alaska USFWS AOP design criteria be used?

After award, the proposing contractor will work with the Tribe on providing funding and funding requirements. It is anticipated that the selected consulting team must verify land ownership and confirm which Alaska USFWS AOP criteria apply. They should provide the criteria they determine to be correct in their professional judgment and in the best interests of the project and project funding requirements.

1. What does the (2) after “Experience of Key Staff and Personnel” indicate? Is this the number of pages or number of staff?

The “(2)” indicates the minimum number of key staff members to identify.

1. Are the 8 content pages allocated flexibly, or do any sections (cover letter/page, resumes, key staff) count toward the limit?

The 8 content pages can be allocated flexibly amongst the required documents.

1. Are the cover page and/or cover letter included in the 8-page count?

The cover page and cover letter both count toward the 8‑page limit.

1. The solicitation identifies this as an Indefinite Delivery/Indefinite Quantity (IDIQ) Single Award Task Order Contract (SATOC). However, there is some language that alludes to the potential for multiple firms to be involved: "the selected engineering firm or firms," "selected consultant(s)," etc. Can you confirm whether this means multiple proposals will be accepted to provide services under the IDIQ or does this mean you anticipate that a single proposal may included multiple firms forming a single proposal.

YTT’s intent is to select one proposal which may have multiple firms performing various aspects of the work beneath one prime consultant.
