About this file
This is a Questions and Answers (Q&A) document for Amendment 01 of federal solicitation 140P2026R0086 for construction work at Knife River Indian Village National Historic Site (KNRI 257081). The document addresses eight contractor inquiries regarding project execution and compliance matters.
Key clarifications from the Q&A include: (1) seasonal work restrictions near water remain in effect (April 15 – June 1 for fish movement), with TBD status on portadam system alternatives; (2) CPARs and Past Performance Proposals (PPO) are acceptable for past performance evaluation; (3) the 42% Small Business subcontracting goal is not a requirement—contractors should reference updated attachment B08 Section J for revised guidance; (4) the proposal due date has been extended to August 20, 2026; (5) same-day work completion/stabilization requirements may be waived if work areas are protected from riverflows via portadam systems, though housekeeping and orderliness standards remain applicable; (6) riprap volume calculations are TBD regarding whether underwater fill sections are included; (7) the permanent stockpile area will be limited to excess materials generated by the project rather than requiring contractor-supplied imported material, though stockpile elevation should approximate anticipated grades per Stantec calculations; and (8) riprap from temporary river crossing removal may be reused for embankment stabilization if materials are similar in size and color to approved specifications, with grading profiles properly accounted for near project timeline completion.

KNRI 257081, Knife River Indian Village National Historic Site
Question No. Sheet or Reference Question Response
Previous Q&As that were provided with the project documents mention work near or in the water should avoid April 15 - June 1 to allow for seasonal fish movement. If contractor plans to utilize portadam systems to allow water movement in half of the river, while the other half / work area is drained, would contractors be allowed to work in the other half of the waterway during this period?
TBD.
Asked in previous Q&As but not answered previously, would contractors be able to utilize CPARs for past performance?
Yes, CPARS or PPQ may be used for Past Performance.
NPS subcontracting plan is showing 42% Small Business goals. If general contracting is self-performing the majority of the work on this project, will NPS be understanding of significantly reducing SB participations?
The 42% is not a requirement. Please see updated attachment (B08_Section J_Attachment 09_Solit_PSP_Vol_II_SubKPlan).
Would NPS be willing to extend the proposal due date? Yes. Proposals are now due August 20, 2026.
On Plan Sheet 2 of 21, Construction Sequence Note 2 calls for work sections to be completed/stabilize in a single day. If contractor is working behind portadam systems where the work area is separated from river flows, can the same day completion/stabilization requirement be eliminated?
Yes this requirement can be waived if protected from riverflows by the portadam. However, good project housekeeping/orderliness will still apply.
6 ` Does the riprap volume on Sheet 2 include the riprap volume necessary for the underwater fill section required for embankment construction?
TBD.
If project does not generate enough material to fill permanent stockpile area to grades as shown, will contractor be liable for importing material to fill to grade lines? Or will the permanent stockpile area be limited to the excess materials generated from the project?
The stockpile area will be limited to the excess materials generated from the project. However, it should end up somewhat close to anticipated grades as Stantec did all the calculations.
Question No. Sheet or Reference Question Response
Upon removal of the temporary river crossing, would contractors be allowed to utilize the riprap for reinstallation at the embankment stabilization work area? Or would this riprap need to be removed from the project?
Yes; assuming the riprap is of similar size/color of what utilized/approved on the embankment stabilization portion of the project. Additionally, grading profile should be properly accounted for this additional rip that we assume would be installed near the end of the project timeline.
