The Navy is about to rebuild the utilities under a shipyard that cannot stop working. Naval Facilities Engineering Systems Command Atlantic has awarded 1080 Constructures, an Omaha firm, a firm fixed-price contract worth more than $634 million to recapitalize power and water at Portsmouth Naval Shipyard. Construction starts in October 2026 and runs to an expected December 2031 completion.
The site is Seavey Island, 278 acres at the mouth of the Piscataqua River between Kittery, Maine and Portsmouth, New Hampshire. The yard overhauls nuclear submarines, and it will keep doing that for the entire five-year construction window.
What the P-1080 scope actually covers
Power distribution upgrades, energy storage, on-site generation, a substation renovation and new natural gas generators on the electrical side. New 12-inch to 16-inch water mains and a new water tower on the water side. The yard already runs a combined heat and power microgrid that is seasonally balanced against shipyard steam demand, and the project expands it.
NAVFAC declined to publish the microgrid expansion specifics or the water tower capacity, citing operational security. That is worth noting: the public scope has a hole in it, and any subcontractor pricing this work will be doing so against information released selectively.
Phased cutovers under live operations
The conditions are the job. Rocky subsurface, a high water table, and mission-critical operations that cannot take an outage. Delivery depends on temporary utility lines and phased cutovers rather than a clean tie-in, which is the same sequencing problem that runs hospital, data center and industrial retrofit work.
Then there is the heritage overlay. Fifty structures on the island sit on the National Register of Historic Places, among them a 120-year-old granite pump house with an opening copper roof and original pumps designed by Thomas Edison. Trenching a new main across a National Register district is a different exercise from trenching across a greenfield.
The work sits inside the Shipyard Infrastructure Optimization Program, which covers all four public shipyards. SIOP director Russ Gagner and deputy Lee Enzastiga at NAVFAC Atlantic are running it, with Nate Maher as deputy officer in charge of construction at the yard.
Read the December 2031 date as a target
Every operational detail here comes from NAVFAC and Navy statements. There is no independent verification of scope or schedule, and on a five-year utility recapitalization executed around live nuclear work, a stated completion date is a plan rather than a commitment.
For New England civil, electrical and mechanical subs, the more useful number is the front end: work starts in about a month and runs five years. Compare it with the multi-contract offshore staging problem at Empire Wind 1, where the marine terminal rebuild had to finish before the turbines could move. Federal work in the region is not thin. It is just sequenced around somebody else’s operations.
