Pittsfield, Maine-based Cianbro Corp. recently began structural repair and restoration work on the Portsmouth Naval Shipyard. 

The firm was awarded $17 million in incremental funds under a federal contract before beginning work on Oct. 23, according to a spokesman for the Naval Facilities Engineering Command Mid-Atlantic. Located in Kittery, Maine on the southern boundary of Maine near Portsmouth, N.H., the shipyard is responsible for the overhaul, repair, and modernization of US Navy submarines.

The modification work at the shipyard’s Berth 11C follows a $28.8 million contract Cianbro awarded by the U.S. Navy in November 2016 for similar structural work at Berth 11A and 11B. The most recent award brings the total value of the contract to nearly $46 million.

“The work will repair existing support structures that will restore the load-carrying capacity of the crane rail system along the waterfront and provide corrosion protection of the wharf to allow continued optimal use of the facility,” the spokesman said.

He says restoration of the crane rail “will allow for unrestricted use of 60-ton portal cranes at Berth 11, used to support overhaul and maintenance of the Navy's fast-attack submarine fleet. The command builds and maintains sustainable facilities, delivers utilities and services, and provides Navy expeditionary and combat force capabilities.”

In a joint statement, U.S. Senators Susan Collins and Angus King said, “the work done at Portsmouth Naval Shipyard has a direct impact on our national security and this contract for Cianbro will help make sure that the shipyard can continue to carry out its mission efficiently and safely.” 

Under the fixed-price construction modification contract, the work is expected to be completed by July, 2020.
