Data centre construction faces unprecedented talent and supply chain crisis amid soaring demand

America’s data-centre building spree is running into a labour wall as much as a materials one. In a survey released on 3 September 2026, the Associated General Contractors of America and NCCER said workforce shortages were the most common cause of project delays, with 42% of respondents blaming shortages of their own workers or subcontractors and 74% reporting at least one significant delay in the past year; among firms that had worked on data-centre jobs, 58% said those project...

That pressure is building because demand is still rising faster than the industry can staff and equip it. DCD Intelligence has said (datacenterdynamics.com) conservative estimates point to global demand for data-centre capacity doubling by 2030, driven by generative AI and other compute-heavy services. Kelly Services said in its 25 August 2026 salary guide (globenewswire.com) that permanent US data-centre employment is expected to reach 650,000 in 2026, up 30% from 2023, while data-centre-related construction jobs are likely to exceed 180,000 through 2028. Kelly also said 25% of data-centre personnel are being hired away by rival hyperscalers or operators, a sign of a poaching market that raises pay without necessarily solving shortages. Joel Leege, Kelly’s president for science, engineering, technology and telecom, said: “The biggest constraint on data center growth is no longer just power, land, or equipment. It’s talent.” (constructiondive.com)

The money at stake helps explain why even relatively small interruptions matter. JLL said in its 2026 Global Data Center Outlook (jll.com) that 57% of data-centre projects suffered construction delays of at least three months in 2025. The same report put average US equipment lead times at 42 weeks, still 83% above 2019 levels, and said developers were pre-ordering some materials as much as 24 months ahead while holding six to 12 months of strategic inventory for critical components. Even so, JLL said the average global build time for a 50MW facility is 18 months and forecast shell-and-core construction costs to reach $11.3 million per MW in 2026, up from $7.7 million in 2020. Gallagher, in an April 2026 risk briefing for contractors, said delays can cost a developer as much as $2 million a day in lost revenue and warned that owners may try to pass those losses down the chain.

The labour squeeze is being intensified by demographics and by the specialist nature of the work. Data Center Dynamics reported in May that more than one in five US construction workers were over 55 in 2024, while ABC estimates the wider industry will need up to 349,000 additional workers in 2026 alone. (datacenterdynamics.com) Anirban Basu, ABC’s chief economist, said delays in other construction categories were “unlikely”, but that shortages among specialist trades were causing problems that were close to unique in data centres. The same DCD analysis said equipment lead times can run from eight to 24 months, with transformers taking up to 210 weeks, and quoted Deloitte’s Kelly Marchese saying custom-built equipment only lengthens the cycle. On staffing, her summary was blunter: “there’s not enough of them to go around.” (datacenterdynamics.com)

Procurement strategies have made some operators stronger, but they have also made the ecosystem more fragile. KPMG wrote in 2024 (kpmg.com) that hyperscalers such as Google and Microsoft increasingly control sourcing for generators, UPS systems and switchgear directly, giving them more visibility and bargaining power. Smaller developers, by contrast, cannot as easily stockpile equipment or negotiate preferred terms, leaving them more exposed to shortages and price swings. KPMG quoted a data-centre construction executive saying: “The industry is over-reliant on a few key suppliers. If we don’t diversify, we’ll continue to face delays and increased costs.” The firm also said offsite modularisation can cut on-site labour and improve quality control, but reduces direct oversight of factory-built components, creating the risk that problems surface only when modules arrive on site.

That is the context in which suppliers such as Fastenal are pitching logistics as a schedule-protection tool rather than a back-office function. In the gb&d interview that prompted the discussion, Mike Lizzi of Fastenal said (gbdmagazine.com) one halted crew can set off “a domino effect down the chain of other sub-GCs.” He said a site with 150 idle workers for five hours would lose more than $48,000 in direct labour at an average wage of $65 an hour. Fastenal says its answer is to put stock closer to the point of use through multiple supply cribs, vending machines, bin systems, kitting and RFID-tagged two-bin Kanban replenishment, backed by cloud tracking and local staff rather than a single central stores counter. Lizzi said the company’s vending machines can cut consumption by at least 30% because every withdrawal is tied to an individual badge swipe. (gbdmagazine.com)

Gallagher’s warning is that the consequences do not stop at inconvenience. Its briefing said long-lead items such as generators, transformers and switchgear can carry lead times of 12 to 18 months, while semiconductors, switchgear and cooling units may have limited supplier bases, forcing contractors into premium purchases or redesign if something slips. Brian Cooper said: “Given the very short time frames in place for these projects, the demand for labor in these trades can be a challenge,” and Gallagher added that experts maintain nine out of 10 data-centre construction projects are delayed, with an average overrun of 34%.

Contractors and developers are beginning to adjust. Kelly recommends pulling recruits from adjacent sectors such as telecommunications, utility grid operations and industrial HVAC, then moving them through rapid upskilling programmes. (globenewswire.com) AGC’s latest survey said more than eight in 10 firms are increasing base pay and 36% have started or stepped up spending on training and professional development. Some of the largest construction groups, according to Deloitte comments reported by DCD, are already reassessing project portfolios and investing in capabilities for mega-projects. (agc.org) But as long as speed to power remains the top site-selection criterion, as JLL found (jll.com), the sector will remain unforgiving: a shortage of electricians, a late transformer or, at the sharp end, a missing box of gloves can all still push a multi-billion-pound timetable off course.
