The turf model is dead. Here is what it changes for subcontractors.

For about fifteen years, the way work reached a tower crew looked like this: a carrier handed a region to a turf vendor, the turf vendor handed pieces of it to a general contractor, the GC handed pieces of that to a subcontractor, and somewhere below that a crew climbed the tower. Every layer took a margin. The crew at the bottom carried the insurance, the training, the trucks, and the risk, on a rate that had been marked down four times before it reached them.

That structure is being dismantled. Not gradually, and not by one carrier.

What actually changed

Between May and December 2025, the National Association of Tower Erectors reached agreements with all three national carriers — Verizon in May, T-Mobile in July, and AT&T in December. The AT&T agreement was filed with the FCC under WT Docket No. 25-150 and is the most detailed of the three.

Its core structural change took effect in June 2026: AT&T hires a single general contractor and permits only one approved subcontractor tier beneath it. The multi-layered turf vendor arrangement is gone. Alongside it come a set of commercial terms that read like a list of the industry's oldest complaints:

• Site-specific compensation replaces matrix pricing — the flat rate schedule that paid the same for a straightforward swap and a nightmare of a site.
• Regional RFPs instead of one national rate card.
• 30-day payment terms after project completion.
• Elimination of factoring fees, and reimbursement of third-party vendor-management platform fees (Avetta, Ariba and the like) that contractors previously absorbed.
• Annual pricing reviews, overseen by a joint NATE–AT&T working group.

If you have been in this business a while, that list is remarkable. It is also not free.

The part that lands on you

The same agreement tightens who is allowed on site:

• At least 50% of tower workers must hold valid NWSA credentials.
• I-9 verification is mandatory for all personnel.
• There are restrictions on 1099 / independent-contractor labor.
• Work goes only to compliant vendors.

None of these are brand new as written policy. As Wireless Estimator reported, AT&T had nominally observed the 50% NWSA threshold for at least three years. T-Mobile's expectation in most markets is likewise that half the crew holds TT-1. What changed is that the requirement now sits inside a signed framework with a working group attached to it, and the intermediary that used to absorb the paperwork has been removed.

That is the shift worth internalizing. The turf vendor was not only taking a margin. It was also standing between you and the compliance burden. When there is one GC and one tier of subs, the GC has nowhere to push verification. It pushes to you.

What this looks like on a Tuesday

Concretely: a GC calls, needs a crew Thursday, and asks you to confirm that half the people you are sending are NWSA-current. You have four climbers going. You need to know — not believe — that at least two of them hold valid credentials, that none of them lapsed last month, and that you can produce the evidence.

Most contractors answer this today with a shared drive of photographed cert cards and somebody's memory. That works until the day it does not: the card expired in March, the guy you were counting on is on another job, or the person asking wants it in writing before the crew rolls.

The same logic applies to the work itself. With fewer layers, the closeout package you send is read by someone closer to the money, with a shorter tolerance for a missing grounding photo.

What to do about it

Three things, in order of how quickly they will bite:

1. Know your certification position today. Not the folder — the number. How many of your climbers hold current NWSA credentials, who lapses in the next 90 days, and who has nothing on file at all. That last group is the one a spreadsheet of certificates structurally cannot show you, because they have no row in it.

2. Make the evidence producible. "We have it somewhere" is not an answer to a GC asking on a Wednesday afternoon. The test is whether you can send something credible within the hour.

3. Tighten the closeout. Fewer layers means less buffer between a sloppy package and a rejection. Rejections cost a truck roll, and a truck roll costs more than the margin on the site.

The commercial terms in these agreements are genuinely good news for contractors who can meet the bar. That is the catch in the sentence: who can meet the bar. The industry spent two years losing companies that could not operate compliantly at matrix pricing. The new framework pays better and asks for proof. Being able to produce that proof quickly is now part of what you are selling.
