(a) 1.2.3 Sea Turtle Protection

1.2.3.1 Payment

Payment for fabrication of Turtle Deflector Device will be made for “Sea Turtle Protection, Section Nos. 5, 6, 7, 8, 9, 10, 11, and 12” in Schedule No. 1, “Sea Turtle Protection, Section Nos. 13-23” in Schedule No. 1 and for “Sea Turtle Protection, Section Nos. 1, 2, 3, and 4” in Option No. 1, "Sea Turtle Protection, Section No. 24” in Option No. 5 and “Sea Turtle Protection, Section Nos. 25 and 26” in Option No. 6 “, which will include the costs of materials and other execution requirements for Turtle Deflector Device and Endangered Species Observers associated with the protection and monitoring of sea turtles as specified in, the SECTION 35 20 23.14 45 PROTECTION

OF SEA TURTLES.

(2) SECTION 35 20 23.12 45, HOPPER DREDGING –

(a) 3.1.1 Quantity Summary The quantities listed in Appendix 1 - QUANTITY SUMMARY TABLE include the volumes present at the time of the surveys indicated on the Contract drawings, plus anticipated shoaling before dredging begins. For the purpose of acceptance, the dredging work in the Contract Line Item Number (CLIN) of the Bid Schedule is divided into Sections.

Section No. 24 will be dredged by others prior to start of work under this contract. Quantity listed in Appendix 1 - QUANTITY SUMMARY TABLE for Section No. 24 is based on anticipated shoaling occurring between completion of that pipeline dredging and award of Option No. 5.

d) Government Bidder Inquiry Responses

(1) Bidder Inquiry - Amendment 1; Section No. 24, Option No. 5; Plan sheets C-110 & C-317, C-318, C-319. Cross sections indicate a varying required slope, with a vertical slope starting at -40’ to daylight. The existing grade’s natural angle of repose appears to be a much flatter slope than the permitted 1:5 and 0:1. The dredging of a vertical slope is not constructible. To dredge all material within the required template, Contractors will be required to dredge a large amount of non-pay material in order. Can the USACE please revise the construction drawings with the inclusion of constructible side slopes for the indicated reaches?

Government Response: Shelves are currently in the channel reach but not included in this dredging contract. The shelves will be dredged by others prior to the start of work under this contract. Work in this section will consist of removal of shoaling following completion of separate pipeline dredging contract. Current slopes in dredging template will remain the same.

(2) Bidder Inquiry - The options for Galveston Harbor and Texas City do not include CLINS to address sea turtle protections for those sections.

Government Response: Sea Turtle Protection will be added to the Bid Schedule for Section No. 24 in Option No. 5 and for Section Nos 25 and 26 in Option No. 6.

2. This amendment shall be attached to and become a part of the solicitation.
