The Work Behind the Build
In 2025, the U.S. put roughly $41 billion of data-center construction in place, and 2026 is running materially ahead of that pace. Translate that construction into the labor required to build these facilities, and the number is on the order of 300 million construction-trade hours across just those two years.
At 2,080 hours per year, that is roughly 144,000 full-time work-years. Much of it is skilled, high-paying work performed by electricians, pipefitters, ironworkers, equipment operators, controls technicians, commissioning teams, and the many other trades required to turn an empty site into an operating data center.
The response is often that those jobs are transitory. Of course they are. Construction ends. The electrician finishes the terminations, the concrete crew pours the last slab, and the pipefitters move to the next project. That does not erase the employment that occurred while the asset was being built. We do not discount the jobs created by building a factory, hospital, bridge, or power plant because the construction crews eventually leave.
Three hundred million hours is a very large amount of high-paying employment, transitory or not. And that number captures only part of the work.
A remarkable amount of a modern data center arrives at the site already containing labor. The switchgear was engineered, fabricated, wired, and tested before an electrician ever landed a cable on it. The transformer was wound and assembled somewhere else. The generators, chillers, UPS systems, busway, pumps, controls, and prefabricated assemblies all represent manufacturing work completed before the construction workforce ever touched them.
Behind those manufacturers is another layer producing breakers, relays, motors, compressors, copper bus, electrical steel, and thousands of other components that become part of the finished facility.
When the employment impact of data centers is reduced to the number of permanent employees inside the building after it opens, we are not measuring the employment required to create the asset. We are measuring one small operating slice of a much larger industrial process.
Before we even begin counting that manufacturing supply chain, U.S. data-center construction alone appears likely to consume roughly 300 million hours of skilled construction labor during 2025 and 2026. That is a lot of high-paying American employment to dismiss as transitory.
