The MTA's Construction & Development division has put the systems, finishes, entrances and ancillary buildings package for the Second Avenue Subway Phase II extension out to bid, with proposals due November 10 at 2 p.m., according to the agency's own solicitation listing under contract number 0000562121.

This is the build-out package for the long-planned Harlem extension of the Second Avenue line — the work that turns tunnel into station: finishes, entrance structures, ancillary buildings and the systems that go inside them. It's a separate procurement from the structural and civil work already under contract for the same extension, which is standard for a project this size: the MTA breaks a mega-project into packages so more firms can bid pieces of it instead of one prime swallowing the whole thing.

The agency's listing does not carry a plan-holder count or an engineer's estimate as of this morning, so there's no way yet to say how many firms are circling this one or what the city expects to pay. Three other MTA design-build Step II solicitations are moving on parallel tracks this month — a station state-of-good-repair package that closed today, a track intrusion detection system job due November 9, and a West Hempstead/Winfield substation replacement due November 17 — all part of the same November wave of transit design-build work hitting the street at once.

For a GC or systems-integration sub watching the Second Avenue Subway program, November 10 is the date to have a proposal in, and the scale of the ancillary-buildings scope means mechanical, electrical and finish-trade subs should be lining up now rather than waiting for a plan-holder list that the MTA has not yet published.

What to do next

If you do systems, finishes or building-fit-out work and want in on Second Avenue Subway Phase II, the proposal deadline is November 10 at 2 p.m. — that's one week out. Pull the solicitation (0000562121) from MTA Construction & Development's current opportunities page directly rather than waiting on a plan-holder list, since none has been posted yet. Firms chasing this one should also watch the November 9 and November 17 MTA Step II deadlines; the same specialty subs likely to bid finishes here are the ones the other three packages are courting too.
