The AI build-out already changed who builds. It’s now changing who manages the build.
Cumming Group said on August 14 that TLM Group, LLC, a New York City owner’s representation and project management consultancy founded in 1999, has merged into its Advanced Technologies division in North America. Terms weren’t disclosed. The combined Tri-State operation now runs past 260 professionals, according to Cumming.
What makes this more than a routine tuck-in is the division TLM landed in. Cumming only created Advanced Technologies in March 2026, purpose-built for data center and high-tech facility programs. TLM is the first named acquisition into it, and TLM’s book is exactly that: data center programs for financial institutions, hyperscalers and colocation providers across the U.S., Canada and Mexico.
An owner’s-rep roll-up with private equity behind it
Cumming changed hands weeks before this deal. Leonard Green & Partners agreed on June 16, 2026 to buy Cumming Group from New Mountain Capital. So the buyer here is a newly recapitalized platform, and TLM is what it did first with the balance sheet.
It isn’t the first. Cumming has already absorbed LeftField, a Northeast owner’s rep, and a Boston construction consultancy. Three acquisitions in the same discipline is a strategy.
“When we launched the Advanced Technologies division earlier this year, our vision was to build the industry’s premier consultancy for the world’s most complex technology and industrial projects,” said Kevin Klein, executive vice president of Advanced Technologies at Cumming Group, in a statement to Construction Dive. “Welcoming TLM Group accelerates that vision by adding a highly respected team with deep experience managing data center construction programs from concept through completion.”
Why owner’s reps became acquisition targets
Cost consultancies and owner’s reps have historically been fragmented, regional and relationship-driven. A firm with twenty people in one metro could hold a client for thirty years. That model works right up until the client’s next project is a $2 billion campus in a state the firm has never worked in.
Data center programs broke the geography. Hyperscale owners want one representative across a multi-site national program, with the staff depth to run several concurrent builds and the résumé to prove it. An independent regional owner’s rep without a data center portfolio can’t bid that work, and increasingly can’t defend its existing client either. That’s the arbitrage private equity is buying.
The same dynamic is showing up on the delivery side of complex programs, where owners break work into managed packages rather than a single prime contract. The Memphis International Airport terminal modernization runs seven separate construction packages under one CMAR structure, which is the kind of job that only exists because somebody on the owner’s side is capable of coordinating it.
What’s actually verifiable here
Be careful with the numbers. The 260-plus headcount comes only from Cumming’s release, with no breakout of how many came from TLM. TLM has never disclosed revenue, headcount or client names; the hyperscaler and financial-institution client base is the company’s own characterization. The release says the firms “have merged” without giving a closing date.
None of that changes the read. When a PE-backed cost consultancy buys an owner’s rep purely for a data center résumé, the independent firms without one stop being competitors and start being inventory.
