Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the revegetation and canal construction aspects of the opportunity.

• Bald Cypress Sapling Locations & Layout: Saplings are to be planted in all gaps between November 1 and February 28 at a density of 20 feet on center. The NPS recommends saplings be 3+ feet tall, in 1-gallon pots, not fertilized for at least 3 months prior to out-planting, and planted with a staked tree protector.
• Bald Cypress Sapling Source: The contractor must provide the bald cypress saplings. They are not provided by the NPS. The source is not limited to Nicholls State University and can be any coastal Louisiana grower.
• Plugs & Meanders: No plugs or meanders are to be constructed for the Parallel Canal portion of this project.
• Spoils Utilization for Plugs: As no plugs are being constructed, the use of project spoils for this purpose is not applicable.
• Eastern Embankment Treatment: Only the eastern spoilbank of the Parallel Canal (which is also the western spoilbank of the Pipeline Canal) is to be degraded and backfilled. The entire "berm" (spoilbank) between the Parallel and Pipeline canals will be reduced to the same elevation as the surrounding wetlands. Gap cuts or remaining edges adjacent to the remaining spoil bank will have steep (approximately 45-degree) edge slopes running from the spoil banks into the gaps. Gap sizes will be measured from the base of the slope.

These clarifications provide specific details on planting requirements, material sourcing, and construction methods for canal and embankment work, which may affect bidder proposals and cost estimates. No changes to due dates or submission rules were indicated.

Amendment / Modification

• This amendment (0001) is issued to post answers to vendor questions regarding solicitation 140P2026R0036.

• The document does not specify which sections of the original solicitation are affected by these answers.

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the Parallel Canal backfill project, clarifying requirements and specifications.

• Canal Backfill Dimensions: The project involves backfilling a 9,200-9,500 foot long section of the Parallel Canal. On-site spoilbank material will be used for backfill, with no external material delivery.
• Gapping Spoilbank: Approximately 25% of the spoilbank (totaling 9,200-9,500 LF) on the east side of the Parallel Canal, between Parallel and Pipeline canals, is to be gapped. The exact number, location, and size of gaps will be determined during preconstruction by the contractor and the NPS. An example provided suggests 24 gaps of approximately 100 ft each could meet the 25% requirement.
• Check Meander: There will be no check meander installed for this project.
• Registration in SAM: Offerors are required to be registered in the System for Award Management (SAM) at the time of offer submission and award, as per FAR 52.204-7(b)(1).
• NAICS Code: Bidders must have and represent in good faith the NAICS code 238910 and its corresponding small business size standard as identified in the solicitation to be eligible for award.

This Q&A document clarifies key aspects of the project scope, particularly regarding spoilbank gapping and dimensions, and reinforces the requirement for SAM registration and correct NAICS code representation. It does not appear to alter submission deadlines or evaluation factors.
