05 Mar 2026: The infrastructure boom is real. So is the capacity crunch.

Five stories, one shared theme: the next decade is being shaped by fewer, bigger, more technical builds. Tutor Perini’s record year hints at a shrinking pool of contractors who can execute $2B+ civil work. Gateway shows how fast a megaproject can get knocked off rhythm when funding certainty wobbles. Canada’s engineering giants are telling investors to calm down about AI, while quietly buying the tools and talent to scale it. Turner’s backlog is now dominated by data centers. And TerraPower just got a rare U.S. nuclear construction permit, with data center power demand sitting in the background of the whole thing.

01 · Contractor Earnings

Tutor Perini just had its best year in 130 years

Tutor Perini posted record revenue and cash flow and swung from adjusted losses to meaningful profitability. The interesting part is not just the numbers. It’s the dynamic the CEO highlighted: fewer contractors can take on multi-billion-dollar civil work, so the ones that can are starting to get better contract terms and stronger margins.

02 · Megaprojects

Gateway restarts work, but the money still feels shaky

The Hudson Tunnel Project has resumed limited work, but a court filing suggests the U.S. DOT is actively trying to reclaim funds already disbursed. Even with reimbursements released under a temporary order, the threat is that cash could be pulled back again. For contractors and subs, this is the kind of uncertainty that forces stop-start planning, demobilisation risk, and expensive schedule resequencing.

Hook: If reimbursement certainty is this fragile, do contractors start treating federal funding as a priced risk item? (Construction Dive)

03 · AEC and AI

Canada’s engineering giants tell investors to stop panicking

The CEOs of WSP and AtkinsRealis are pushing back on the idea that AI is about replacement. Their message is basically: engineering is judgement-heavy work, and AI is an enabler, not a disrupter. The more interesting subtext is that scale matters. They’re signalling they can invest in AI at a level smaller firms can’t, which could pull the market toward more consolidation.

Hook: If the big firms are buyers, not victims, what does that mean for every AI startup trying to sell into AEC? (ConstructConnect)

04 · Data Centers

Turner’s boom year shows how dominant AI infrastructure has become

Turner reported 2025 revenue of $29.2B, up roughly 40 percent, with backlog at $44.3B. The standout detail is mix. Data centers now represent 37 percent of Turner’s backlog. That’s not a niche. That’s a pipeline shift. For a lot of general contractors, data centers are becoming a core margin engine, not just a side business.

Hook: If data centers keep eating the backlog, which project types get squeezed out and which contractors will pivot fastest? (Construction Dive)

05 · Energy and Infrastructure

TerraPower gets a rare U.S. nuclear construction permit

The NRC approved TerraPower’s sodium-cooled reactor project in Wyoming, the first U.S. commercial reactor construction permit in years and a rare approval for a non-water reactor design. The project is pitched as a way to repurpose a retiring coal plant site and provide power for a future that includes more data centers. If this stays on track through the late 2020s, it could reopen a category of construction most people have written off.

Hook: Is this the start of repeatable nuclear builds, or a one-time exception that never scales? (CT Insider)

The thread

These are all capacity stories. Fewer contractors can take on mega civil work. Federal megaprojects still struggle with payment certainty. The biggest engineering firms are positioning AI as a scale advantage, not a threat. Data centers are pulling resources into a single project type. And power supply is becoming inseparable from construction strategy.

One practical move this week

Pick one live programme and do a simple "capacity audit": who can actually deliver your next two critical packages (people, trades, long-leads), and what happens if one of them slips by 30 days. If you cannot answer fast, you have a hidden schedule risk.
