Walbridge's L5 Mission Critical hires JLL's data center chief

Walbridge has handed its new data center subsidiary to JLL's data center chief, Matt Landek, who ran data centers and critical environments globally at JLL and is now president and CEO of L5 Mission Critical, the builder's stand-alone arm. The division pairs Walbridge's construction capacity with L5's operational assistance for owners moving a facility from commissioning into facilities management, targeting third-party data center clients rather than Walbridge's own book.

The offer lands on a delivery market with no slack. U.S. data center capacity is expected to double within three years, with nearly 45GW of additions planned on AI and cloud demand, according to Data Center Frontier, and JLL's 2026 North America Data Center Midyear report has most tenants securing space in small, fragmented blocks and contracting for 2028 deliveries. Morningstar's Aug. 5 commentary draws the consequence: development pipelines are being disrupted, pushing demand toward existing stabilized data centers, whose contractually reserved capacity largely protects them from grid constraints and new interconnection moratoriums.

That is the existing-stock mirror of the argument that grid permission, not capital, is the underwriting asset. A hall that already holds power is insulated; a project holding only a queue position is exposed. A service built around the final year of a build has a market because whoever signs a 2028 delivery contract is buying into a market where finished, energized capacity is the scarce commodity.

Landek's pitch is narrower than the buildout. He told Facilities Dive by email that L5 will differentiate itself by owning the handoff from construction and commissioning into live operations, which he called the gap where most new data centers struggle through their first 12 months and one no other provider has an incentive to close because each touches only a single link in the chain. The supports are an operating model built for hyperscale from the start rather than retrofitted from legacy practice, a century of Walbridge experience running complex mega-facilities, and a workforce and community program that goes beyond what service providers typically offer. Walbridge president and chief administrative officer John Rakolta III put the client need as getting projects up and out of the ground fast, plus operations that reduce risk, ensure uptime and educate communities.

The seam is a defensible place to build a services firm because investors in digital infrastructure get paid at energization, not at substantial completion, and the commissioning, systems integration and staffing that turn a shell into revenue sit inside the riskiest stretch of the schedule. The delivery constraint has moved into supplier slots and raw materials, with staffing the final bottleneck before energization; L5 is selling into precisely that bottleneck, and JLL's own Sean Farney notes that many existing halls cannot support the liquid cooling AI compute requires but can be retrofitted—retrofit and stabilization work that lands in an operator's budget. The unproven part is the fee: L5's case rests on the seam being genuinely unowned, and it has to hold up against whatever the owner believes it already bought in an EPC scope or a facilities contract.

Walbridge is buying a résumé with a pattern in it. Landek led JLL's expansion into data centers through acquisitions and internal initiatives, including the 2024 purchase of SKAE Power Solutions, which was combined with other operations into a technical services division under him. Doing that inside a contractor rather than a brokerage is a different exercise, and the test is concrete—a first named client and a contract that puts L5 on the hook for uptime, more than a seat at the commissioning table.
