About this file
This document is a Questions and Answers (Q&A) amendment for National Park Service (NPS) contract KNRI 257081 concerning construction work at Knife River Indian Village National Historic Site. Amendment 02 was issued on July 29, 2026, with proposals due August 20, 2026.
The Q&A addresses twelve key inquiries covering environmental restrictions, past performance documentation, subcontracting requirements, scheduling, material quantities, and personnel staffing. Notable responses include: work during the April 15–June 1 fish movement season may proceed if portadam systems protect riverflows; both CPARs and Past Performance Questionnaires are acceptable for demonstrating past performance, including previously completed documents; the 42% small business participation goal is not a binding requirement and contractors should reference the updated subcontracting plan; same-day work completion requirements may be waived when using portadam systems; riprap from temporary river crossings may be reused for embankment stabilization work; an offer guarantee is required despite initial SF1442 language indicating otherwise; and one individual cannot serve simultaneously as Superintendent, QC Manager, and Safety Manager, though dual-hatted positions are prohibited. Several technical questions regarding riprap volume calculations and material stockpile liability remain to be determined (TBD).

140P2026R0086 / Amendment 02/
07.29.2026
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.
SF1442 Box 13 indicates that an offer guarantee is not required, but Section L lists a bid bond/offer guarantee as a requirement in Volume II. Is an offer guarantee required for this proposal?
Yes , an offer guanantee is required. See revised SF1442 attached to Amendment 02.
Can Final CPAR Evaluations be submitted in lieu of obtaining new Past Performance Questionnaires?
Yes.
Can previously completed Past Performance Questionnaires (PPQs) be submitted in lieu of obtaining new PPQs?
Yes as long as it pertains to the same type of work.
Can one person triple hat as Superintendent, QC Manager and Safety Manager? No, dual hatted positions are not allowed.
