On paper it is maintenance work: clean, repair and replace drainage at three locations — Route 111 in Islip, Route 107 through Old Brookville, and Route 25 at Laurel Lane in Southold. The documents, which this desk has read, tell a more interesting story, and bidders have until the September 17 letting to absorb it.

Start with the deadline inside the deadline. The contract runs to March 2028, but everything at the Route 111 location — drainage, pavement restoration, striping — must be finished by May 31, 2027, with its own liquidated damages behind it. Whatever sequence a bidder plans, Islip goes first.

Then the surprise at Laurel Lane: a full water-main relocation riding inside a drainage contract. About 906 feet of 12-inch ductile iron goes in and 914 feet of old main comes out — and the Riverhead Water District requires the water work be performed by a district-approved subcontractor. Only approved firms may touch valves, overnight customer shutdowns are prohibited, and material approvals take about two weeks. A drainage prime that shows up without that sub lined up has a problem. The utility choreography extends further: National Grid needs ten weeks for its gas relocation and Verizon eight for its conduit, both starting only after the contractor lays out the drainage in the conflict zone — and several structures on Route 111 sit under PSEG transmission lines the plans flag as possibly requiring de-energizing.

The quantities are unusually countable. The plans map all 68 drainage structures one by one — station, treatment, and connecting runs — anchored by 1,711 feet of 15-inch concrete pipe, 4,162 cubic yards of trench excavation, 23,000 square feet of modular shoring, and a cleaning program running from 32 structures through nearly a thousand feet of closed drains. A sitework estimator can count every hole in this job from three sheets.

It is night work almost everywhere — no closures at peaks, Route 107 touchable only between 10 p.m. and 6 a.m., and summer daytime closures banned entirely at the Southold end. Tree removal is confined to December through February for endangered bats, and two temporary waterway diversions put live-water rules in play. The federal DBE goal is zero percent — on a roughly $4 million contract, the state's own signal that small drainage and sitework outfits can chase this one directly as primes.

The full proposal books and plans are free on the state's contract-documents page, along with the quantity workups a serious estimator should pull. Letting is September 17 at 10:30 a.m. in Albany, by Bid Express or paper — and note the state's newer rule: contractors must be registered with the Labor Department before bidding, or the bid is set aside.
