The US Navy has awarded a $191.9 million design-bid-build contract for the recapitalization of the dry dock at Naval Submarine Base (NSB) Kings Bay, Georgia.

“The overhaul and restoration of the Kings Bay Dry Dock is the most important strategic deterrence enterprise modernization effort outside of the construction of the new Columbia-class SSBN, a nuclear-powered ballistic missile submarine,” said TRIDENT Refit Facility Commanding Officer Capt. Paul Dinius.

The navy’s submarines serve as the nation’s sea-based deterrent strategies. The dry dock recapitalization project at NSB Kings Bay is in direct support of the future of submarine warfare. The new Columbia-class submarine is replacing the Ohio-class submarine.

The work to be performed includes concrete and steel repairs, overhaul and repair of the steel caisson and upgrades to power distribution, chilled water and fire detection and alarm systems. The entire superstructure will be re-coated, along with replacement of the roof, wall panels, and other plumbing and piping. The control system, electronic components and the auxiliary seawater system will also be upgraded.

All existing training and maintenance facilities will be retrofitted and some new facilities will be constructed to support the next generation of submarines.

In order to meet this tight deadline, NAVFAC Southeast has established a Construction Management Office (CMO) on site at NSB Kings Bay with dedicated resources capable of supporting 24 hour a day activities.

The contract also contains unexercised options, which if exercised, would increase the cumulative contract value to $592.3 million.

The work will be performed by the Alberici-Mortenson joint venture which is set to complete it by July 2023.
