SPEC SECTION/DRAWING RFI QUESTION RESPONSES

1 Topic: Dredging Reaches

Drawing: G-002

Section: Bid Schedule

Subpart: N/A

Specification Language:

1.1 Question: The Bid Schedule lists 23 reaches to be dredged and based on the depths shown, Reach 22 corresponds to the Sediment

Trap. However, the Plans and language in the specifications reference 15 dredging reaches with Reach 15 corresponding to the

Sediment Trap. Please clarify which is correct and update the documents for consistency between the Bid Schedule and the

Specifications and Drawings

The Bid Schedule is incorrect. For the 15 correct reaches please refer to the plans. The Amendment 0001 Schedule has been issued in SAM.gov.

2 Topic: Reporting of Biobased Products

Drawing: N/A

Section: 00 70 00

Subpart: FAR 52.223-2 Reporting of Biobased

Products Under Service and Construction

Contracts. May 2024

Specification Language:

2.1 Question: Upon careful review, the Contract does not set forth any minimum biobased content percentage for any product within any Biobased Product Category. Because the contract will not involve the use of biobased products in USDA-designated product categories at https://www.biopreferred.gov or 7 CFR part 3201, we respectfully request that you remove FAR 52.223-2 from this

Contract.

Due to the uncertainty of whether the prospective awardee will utilize any biobased products in the USDA-designated product categories, the clause is required at this time.

To clarify the intent of the warranty, please confirm that the warranty provisions do not apply to the dredging portion(s) of the work. With respect to dredging, upon

Contractor’s advising Owner that the dredging has been completed, Owner shall inspect the Work and, if acceptable, shall advise Contractor of Owner’s acceptance thereof. Contractor in no way represents, guarantees or warrants that any dredging or excavation will stay open, dredged or excavated for any period of time whatsoever.

Section: 01 57 19

Subpart: 3.1.4 and 3.1.4.1

Specification Language: 3.1.4: The Contractor will either utilize a fish entrainment device at the point of discharge of the dredged material, sample scows (if dredging is conducted using a clamshell), utilize a fish entrainment device fashioned to work with a clamshell, or other similar methods.

3.1.41: The Contractor shall furnish a fish monitoring apparatus and transport the apparatus to the various dredged material placement sites as well as within each placement sites.

4.1 Question: If 30% of dredged material is

sampled at the dredged site (scow or bucket), is the fish monitoring apparatus still required at the point of discharge?

No, a fish monitoring apparatus is not required at the point of discharge, per the United States Fish and Wildlife Service (USFWS) Stockton Deep Water Ship Channel Biological Opinion (2023-2028) attached to the specifications. The Contractor can propose any methodology so long as the goal of at least 30 percent of dredged material monitored can be met. The Government will review and approve of the methodology via the Submittal: Fish Entrainment and Biological Resources Monitoring Work Plan.

Prism is NOT permitted for the sediment trap.

Specification Language 1.1.1: Dredge the specified dredge reaches to -35-ft MLLW plus

1-ft of allowable paid overdepth in San

Joaquin River / Stockton DWSC in all

Reaches, except for the Sediment Trap, which shall be dredged to -38.5-ft MLLW with 1-ft of allowable paid overdepth.

5.1 Question: The above referenced specification

language is unlcear. Please clarify what, if any, overdepth dredging is allowed for the Sediment

Trap. Does the Sediment Trap include 1’ of paid overdepth to -39.5’ MLLW? If so, is any additional dredging/disturbance allowed beyond this?

The sediment trap includes 1’ of paid overdepth to 39.5’. No dredging below 39.5’ is allowed in the sediment trap per environmental restrictions.

information on how the fish monitoring requirement has been fulfilled with clamshell dredges in the past?

implemented via the Submittal: Fish Entrainment and

Biological Resources Monitoring Work Plan.
