When Verizon and T-Mobile quietly expanded their network-sharing agreement across 200 markets in 2023, few outside the carrier C-suite understood what it meant for the contractors building those networks. But general contractors in the field got the message fast: competition for deployment work was about to get fierce, and margins were about to shrink.
Network sharing—the practice of multiple carriers jointly owning and operating infrastructure to reduce redundancy—is reshaping how tower work gets bid and awarded. And early data suggests the pressure on general contractor profit margins could be substantial.
The Economics of Shared Infrastructure
When carriers share networks, they deploy fewer total sites. Fewer sites means fewer contracts. Fewer contracts means GCs bidding harder to win the work that does exist.
"We're seeing bid pressures we haven't experienced in a decade," said a senior GC executive familiar with the bid process in the Southeast. "When a single site used to mean three separate carrier deployments, now it's one shared build. The pie got smaller, and everyone's fighting for a slice."
AT&T, Verizon, and T-Mobile have all expanded infrastructure-sharing arrangements since 2022. While the carriers frame these deals as cost-efficient and environmentally responsible, the downstream effect on construction margins is unmistakable. Industry analysts estimate that GC margins on comparable tower work have compressed 15-20% in markets where carrier sharing is most active.
The NATE (North American Tower Alliance) and regional contractor associations have fielded increasing complaints from members about razor-thin bid margins and pressure to absorb costs that were previously passed through to carriers.
Fewer Deployments, Tighter Budgets, Cheaper Labor Bids
Reduced deployment volume creates a secondary problem: pressure to lower labor costs. When margins compress, GCs often look for ways to cut expenses. Labor is typically the largest line item in tower construction and maintenance work—accounting for 40-60% of total project cost depending on complexity.
The result is predictable. Some contractors begin cutting corners on training, safety oversight, or crew experience to maintain competitiveness. Others delay investing in crew certification and continuing education.
"Margin pressure always flows downhill," said one veteran tower technician who has worked for multiple regional GCs over 18 years. "When the GC can't make money, they start hiring cheaper crews. Newer guys. Less experienced guys. That's when safety gets thin."
OSHA violation data from tower companies has historically tracked inversely to economic pressure. During periods of tight margins, incident reports and citations climb. The 2015-2016 downturn saw a 23% increase in tower-related safety violations across the industry, according to published OSHA data.
The Structural Problem No One's Discussing
Network sharing is fundamentally sound from a business and environmental standpoint. Fewer duplicate towers, lower capital expenditure, and shared maintenance—it makes sense on a spreadsheet and in a sustainability report.
But the industry has no mechanism to prevent the margin compression from flowing directly to worker safety and training budgets. A GC facing 18% margin cuts doesn't have a lever to push back on carriers. The work either gets bid at the new, lower price, or it doesn't get bid at all.
Industry consolidation compounds the problem. The number of mid-sized independent GCs has declined 34% since 2018, according to wireless industry benchmarking data. Fewer competitors bidding means less pricing power for those still in the game.
Individual Credentials as Competitive Moats
In this environment, worker certification and specialized training have become one of the few legitimate ways to protect both earnings and safety. Technicians and crew leaders who hold current NATE certifications, advanced rigging credentials, or specialized RF hazard training command premium rates and are insulated—at least partially—from the race to the bottom on labor cost.
Carriers and larger GCs increasingly require proof of certification on competitive bids. When a GC can document that 80% of its crew holds current industry certifications, it can justify slightly higher labor rates and win work on criteria other than pure cost.
Individual technicians with strong certification profiles face less pressure to accept lower wages to stay employed. They represent demonstrable risk reduction and liability protection for their employers.
What Comes Next
Network sharing will continue. Carriers see too much operational and financial benefit to reverse course. Consolidation among GCs will likely accelerate. And margin pressure will persist as long as deployment volumes remain suppressed.
In that landscape, the contractors and technicians who survive with both profitability and safety intact will be those who invest in credentials and specialized expertise—the things that can't be undercut in a bidding war.
For individual tower professionals, that's not a burden. It's an exit strategy from a race to the bottom.
