Building Business: By land or by sea, Cianbro answers the call

Maine’s largest construction company, Cianbro Corp., may be best known for its work on land.

But recently it was tasked with transporting a temporary lifting device from Brewer to the Portsmouth Naval Shipyard.

The steel structure is 111 feet wide with a lifting capacity of 4,000 metric tons — so this obviously wasn’t a job to be taken lightly, no pun intended.

The lifting device was transported from Cianbro’s modular manufacturing facility in Brewer. The barge made the journey down the Penobscot River to the Atlantic, then along the Maine coast to the mouth of the Piscataqua River.

The device is temporarily stationed at Henderson’s Point on the west side of Seavey Island.

The shipyard will use the lifting device to support its work at Dry Dock No. 1, which dates to World War II and is undergoing a seven-year renovation process. Cianbro is also a partner in that work, along with 381 Constructors, the Industrial Co. of Kiewit Corp. and the Middlesex Corp. Assembly of the lifting device is expected to wind up in early May.

The device will be used to lift 27 concrete “monoliths” — each weighing 4,000 tons. The concrete structures are being built at Cianbro’s Brewer facility.

Once the modernization of Dry Dock No. 1 is completed, the shipyard will be able to accommodate three Los Angeles- or Virginia-class submarines for repair, maintenance and modernization. The shipyard is one of four owned by the U.S. Navy, which has more than $6 billion in construction upgrades planned under the Shipyard Infrastructure Optimization Program.
