The SCA bid a job on Staten Island in June 2025 and called it early work and site preparation. Four firms bid it. Navillus Contracting took it at $89,433,000, and the market moved on — because site prep is dirt and pipe and nobody writes home about dirt.

Here's what was actually in it. Two hundred fifty-five geothermal boreholes, six inches across, drilled six hundred feet straight down.

“The label said site preparation. The drawings said twenty-nine miles.”

That's off the SCA's own drawings — sheet GEO100, the Overall Geothermal Site Plan, issued for bid on March 6, 2025, and the enlargement sheets behind it. Wells on a 20-foot grid. Inch-and-a-half DR-11 polyethylene down every hole. Twenty-seven circuits running back to a manifold room built under the bleachers of the new athletic field.

Run the arithmetic and it's 153,000 feet of hole. Call it 29 miles of drilling, more than twice the length of Manhattan, pointed straight down under a ballfield. And each one of those 255 holes goes about 200 feet deeper than Todt Hill — the highest natural ground on the Atlantic coast south of Maine — is tall.

Now, why. The two schools going up on that campus don't have boilers. Not high-efficiency boilers. None. A bidder on the next phase noticed the HVAC breakdown had blank lines where boilers should be and asked the agency about it. The answer came back in writing: boilers are not in the scope of work. An earlier addendum had already confirmed there are no boiler or hot-water flues anywhere on the project. The ground is the boiler.

That's city policy showing up as a jobsite. Under Leading the Charge — the $4 billion program announced in 2022 — every new SCA school is all-electric, and 100 existing schools are supposed to be converted by 2030. The city calls it its biggest single move toward the 50% cut in government emissions that Local Law 97 requires. This campus is also built to Local Law 51 of 2023, the city's green-building standard. On top of the ground loop it carries rooftop solar on the IS/HS, the PS/IS and the maintenance building, PV canopies over the parking, and EV charging.

Here's the part that should change how you read the board, and it isn't what the last decade taught you. Electrifying a school used to mean a mechanical contractor swapping a boiler for heat pumps while an electrician upsized the service. This job needed a drilling rig parked on site for months. Two hundred fifty-five holes at six inches is a well-drilling scope — and it got bid inside a site-preparation package, under a GC most of you know for concrete and masonry.

So if you drill, or you fuse HDPE, or you do deep grouting, understand what just happened: a market that didn't exist on the SCA board five years ago quietly ate a large piece of an $89 million contract.

The spec behind it isn't casual about any of it either. Section 15711 puts a minimum 50-year manufacturer's warranty on the vertical loop pipe and its U-bends. The assembled field gets hydrostatically tested at 150% of design pressure. Ethylene glycol and potassium acetate are banned outright as heat-transfer fluid. And the contractor has to carry a contingency for flowing artesian wells — because this is Staten Island, and the water table has opinions.

Two things we won't oversell. The campus is not fossil-free: there's still an emergency generator running on fuel oil, tanks and flues and all. That's normal for life safety, and it's worth saying plainly instead of letting you find out from the drawings.

And we missed this one ourselves. When we charted the collapse of the SCA boiler market last month, we read more than 4,200 solicitation titles looking for the words heat pump and electrification. The biggest geothermal job on the board never said either one. It said site preparation.

That's the lesson worth more than the number. The SCA has roughly 1,400 buildings and a 2030 deadline, and the work that matters is increasingly buried in packages named after dirt. Pull the drawings on anything called early work or site prep at a new school. Look for a sheet that starts with GEO.

The label said site preparation. The drawings said twenty-nine miles.
