SUMMARY OF CHANGES

Section 00 00 00 - Procurement and Contracting Requirements

The following changes have been made:

Miscellaneous text in this section has been modified to:

RFI Disclaimer

Questions that may be of general interest to all Offerors and/or the Government and that are not readily answered by the proceeding changes will appear below. These questions may have been paraphrased or altered to represent several questions regarding the same subject and/or simply revised to clarify and simplify the question(s). Questions and answers are issued to the Offerors "for information only" and do not revise the solicitation, plans or specifications.

Q4. We are looking at the W912DS26BA014 maintenance project in the NY&NJ channel. Project Specs Section 35 20 23 Part 2.1 gives a percentile breakdown of materials in the area based on sampling in 2025, but there is no additional information regarding collection method, testing method, or locations of the individual samples. Could you provide any additional information about the sampling campaign? The material breakdowns vary significantly between reaches which could have significant operational impact.

A4. Please refer to the previous RFI response under Q3/A3.

Q5. This contract requires the material to be dredged by a closed clamshell environment bucket.

These buckets are designed to dredge soft silt and mud. Section 35 20 23 2.1 Character of Material states: "Based on sampling and testing of the proposed dredged material in 2025, the material to be removed consists of primarily, silt, sand, and clay:

a. REACH 1: 59.7% SAND, 26.7% SILT, & 13.6% CLAY

b. REACH 2: 24.7% SAND, 54.3% SILT, & 21.0% CLAY

c. REACH 3: 16.9% SAND, 63.2% SILT, & 19.9% CLAY"

W912DS26BA0140003

These samples contain high sand and clay content which may not be able to be dredged with a closed clamshell environment bucket. On past contracts, were all areas of the project dredged to grade with a closed environmental bucket? If not, which areas required a conventional bucket and how much quantity (CY) was removed with a conventional bucket?

A5. In the past maintenance dredging cycle for NY&NJ Channels-Seguine/Ward/Outerbridge Reaches, all work was able to be complete utilizing a mechanical clamshell dredge with similar material composition throughout the reaches.

Q6. Section 01 11 00, page 3, states; "No dredging activities shall occur from 01 October 2026 to 30 November 2026 for dredging areas in sheets six (6) to ten (10) as indicated in the plan sheets."

There are shoaled areas that are shown on both sheet 5 and sheet 6. Please clarify if the overlapping areas are to be considered part of sheet 5 or sheet 6.

A6. Please refer to the plan sheets. Overlap material between sheets 5 and 6 can be dredged in the alleviated window if material is bounded within sheet 5.
