The bids are in on MTA contract C30855, and the room was crowded. MTA Construction & Development opened fifteen bids on December 10, 2024 for the rehabilitation of substation enclosures — repair work on the buildings that house the equipment powering the subway. FOS Development Corp is the apparent low bidder at $7,449,998, coming in under the bottom of the $10 million-to-$50 million range MTA C&D had advertised when it put the job out to bid.

The top of the tab was tight. M. Bhuiyan Construction Co. came second at $7,857,694 — 5.5 percent above the low, which says two estimators read this job about the same way. S&S Kings Corp was next at $8,493,121, then J-Track LLC at $8,629,254. From there the numbers climbed all the way to Nagan Construction's $14,019,282.50, close to double the low. The big transit names priced it rich — Navillus Contracting sat second from the top at $13,670,119. And the fifteen bids understate the interest: twenty-eight firms pulled the contract documents. Mid-size MTA building work is a market a lot of GCs want in on.

The contract documents name all four buildings. W. 143rd Street Substation (#133) in Manhattan gets the heaviest architectural lift: refurbished steel windows, restored stone and brick facade, cleaned and repainted steel columns and first-floor walls, a replaced steel lintel beam in the basement, waterproofing over the basement slab, new lighting and wiring, and new sump pits. Decatur Street Substation (#70) in Brooklyn and East 161st Street Substation (#88) in the Bronx get lighter work — cracked and leaking roof slabs injected and sealed, rusted structural steel cleaned and repainted. The Bronx site sits on the north side of East 161st Street, right next to Yankee Stadium; a bidder asked during the pre-bid process whether a site trailer would have to come down for game days, and MTA C&D pointed to the site's separate DOT stipulations rather than answering outright. Hunter South Substation (#170) in Queens is the outlier: its scope is built around cleaning up soot and ash from fire damage on the underside of the roof slab, plus a structural-steel condition survey — the only one of the four tied to a fire.

The 143rd Street building carries a weight the other three don't: it's individually listed on the National Register of Historic Places, on record as "Interborough Rapid Transit Company Substation 15." That listing puts a preservation specialist on site for the facade work, with rules on documenting and salvaging any historic material the crew uncovers and hand-tool-only removal near the original stonework. Every site also comes with its own commissioned asbestos survey, and bidders were told to price the full abatement quantities shown on the drawings, not an allowance — one confirmed figure alone runs 3,000 linear and square feet of asbestos-wrapped wiring at the Bronx substation.

Bidders were still working off a moving target close to bid day. MTA C&D issued four addenda, two of them on December 5 — five days before bids closed. The bid form's time-based pricing line, the daily dollar rate tied to the job's 640-day contract term, got revised twice. And a requirement that the contractor carry a dedicated traction-power engineer got dropped in that final round, after bidders pushed back that the only SCADA-adjacent work on the job is wiring one new door sensor back to an existing control box — not the live power-control work the original spec implied.

Here's why a rider should care about buildings most New Yorkers walk past without a glance. The traction power system is what actually moves the trains — it delivers the electricity that pushes every car down the line. When power fails, service fails: by the MTA's own count, a single power incident delays an average of more than 30 trains. And the authority says more than 200 substations across its network are in poor or marginal condition. A sound roof and dry walls are the first line of defense for everything inside. Fixing the shell now beats replacing ruined switchgear later.

The standard caveat carries real weight here — apparent low is not an award. In this case the review is already over: the MTA's own 2024 award list shows the contract went to FOS Development Corp on December 31, 2024, at $5,141,566 — well under the $7,449,998 apparent-low figure read at the bid opening. Reviews sometimes trim a scope or a price; this one moved by nearly $2.3 million between the tab and the signed contract.

The bigger picture is a power program with legs. In laying out its 2025-2029 Capital Plan, the MTA called aging power systems a major vulnerability to reliable service and proposed a full overhaul or targeted component replacement at more than 60 substation locations, plus rehabilitation of 30 circuit breaker houses. For contractors who can do careful structural and envelope work around live electrical infrastructure — including, as this job shows, work that touches landmarked buildings and documented asbestos — this tab isn't a one-off. It's the front end of a pipeline.
