Out on the Hudson River, the city's Department of Environmental Protection has a construction job open for structural improvements to the North River Water Resource Recovery Facility, or WRRF. Bids close at 10:00 AM on December 9.

The job, listed as 82627B0022-BEDC-NR-107, falls under construction and construction services. The posting doesn't give a specific street location or a dollar estimate, and no plan-holder count is listed.

Here's the thing about this plant — it's not sitting on regular ground. The North River wastewater treatment plant is built on a 28-acre reinforced concrete platform over the Hudson River, and the whole thing rests on 2,300 caissons driven into bedrock as much as 230 feet beneath the river. That platform was finished back in 1978, so whatever structural work is being bid here is touching infrastructure that's pushing half a century old, sitting over water, on a foundation most contractors will never work on anywhere else in the city.

That's exactly why this is a specialty job — underdeck and marine structural work over a river platform isn't something every GC can staff or price with confidence. The city has already lined up a separate construction management contract for underdeck structural and marine improvements at the facility, with AECOM USA Inc. proposed at a maximum value of $18,348,344.19 — a sign of how much oversight and complexity this kind of work carries.

If you've got marine or heavy structural experience and the bonding capacity to match, this is worth your estimating time. Pull the solicitation for 82627B0022, study the scope closely given the site's unusual foundation, and get your bid in before the 10:00 AM close on December 9.
