Under paragraph 1.4.d (3), add the following item:

“1.4.d (4) Contractor must not stage or utilize Berths 40 & 41 for any work involved with this project.

Due to laydown requirements of concurrent projects (see RELATED PROJECTS below), the Contractor must utilize the P678 Dry Dock 8 Saltwater System laydown areas as indicated or as designated by the Contracting Officer.”

After subparagraph 1.4.e add the following items:

“f. A ship will be drydocked at Dry Dock 8 until the end of November 2022. The Contractor is not authorized to start onsite demolition or construction work before 16 January 2023.

g. The Contractor must coordinate the work of this project with the projects listed under paragraph

RELATED PROJECTS below.

h. Coordinate construction of the temporary Pumpwell 8 suction culvert plugs to occur prior to Caisson

8 being removed from Government property for renovations (See RELATED PROJECTS below).

Anticipated Caisson 8 removal is November 2023. Anticipated Caisson 8 return is July 2024.

i. The Government will flood the dry dock to flip the Caisson for retrofit work on “Side B” no earlier than 1 May 2023 and no later than 5 June 2023. The dock will be dry until this time, and temporary suction culvert plug work may proceed prior to “Side B” retrofit.

j. Ater the Caisson is flipped to “Side “B”, the Caisson 8 Contractor will dewater Dry Dock 8 so

Caisson in-dock work can proceed, no later than 1 July 2023.

k. The Government will flood the dock for the Caisson to be removed and transported to a shipyard for remaining modifications, no later than 13 November 2023.

l. Once the Caisson is returned and seated in the dry dock, the Contractor will be required to dewater the dock utilizing temporary pumps in order to remove the temporary suction plugs.

m. Once the suction plugs are removed, the Government will flood the dock for the Main Dewatering

Pumps to be tested. Once these tests are completed and approved by the Contracting Officer, the Contractor will be required to operate the Main Dewatering Pumps so that certification testing of the Caisson 8 Flood Through Valves can begin. There will be four complete dewaterings required for the Caisson 8 certification testing.

n. Coordinate the North and South Flooding flume work with the project, RM22-0455 Repair Berths 40 and 41(See RELATED PROJECTS below). The North and South flooding flume work shall not commence until Beneficial Occupancy of Berth 40 and Berth 41 are achieved.
