Commander, Navy Installations Command (CNIC) Design-Bid-Build, RM-23-1146 Dry Dock 2 Caisson Overhaul at Portsmouth Naval Shipyard (PNSY) in Kittery, Maine

Background
The Commander, Navy Installations Command (CNIC) is contemplating an award for a Design-Bid-Build project titled RM-23-1146, which involves the overhaul of the Dry Dock 2 Caisson at Portsmouth Naval Shipyard (PNSY) in Kittery, Maine. The primary goal of this project is to perform necessary maintenance to ensure the caisson's certification and functionality. This includes extending the caisson seat and vertically extending the existing caisson to maintain continuous flood protection from Berth 6 through the caisson to Berth 5.

Work Details
The project entails a comprehensive overhaul of the Dry Dock 2 Caisson, which includes:
- Required maintenance to maintain certification of the caisson.
- Caisson seat extension.
- Vertical extension of the existing caisson.
- Ensuring continuous flood protection from Berth 6 through the caisson and to Berth 5.
- Portions of work will need to be executed with the caisson out of water.

Period of Performance
The geographic location(s) the construction projects will be performed (if provided)

Place of Performance
The construction projects will be performed at Portsmouth Naval Shipyard (PNSY) in Kittery, Maine.

Bidder Requirements
Bidders must demonstrate experience with relevant construction projects that meet specific criteria:
- Experience with projects valued at $10,000,000 or greater.
- Experience with construction, renovation, repair, and/or certification of caissons or floating vessels.
- Demonstrated capability in placing a caisson or floating vessel in a dry dock or similar facility.
- Experience working on a caisson while it is in a dry dock or other facilities.
- Submission of a capabilities package including relevant project information forms and evidence of past contracts similar in nature is required.

Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a confirmed incumbent and/or closely related prior contract based on N4008522C0010, awarded to Bollinger Shipyards Lockport for construction of two graving dock caissons for PNSY’s Dry Dock #1N and #1W, including steel fabrication, installation of mechanical and electrical systems, and full testing of the caissons and their interface with dry dock seats. The current RM-23-1146 effort similarly involves work on caissons at Portsmouth Naval Shipyard to maintain certification, including caisson seat extension and vertical extension, with portions performed with the caisson out of the water—suggesting continuity in caisson design/fabrication and integration work at the same facility.
