Updated monthly. [![Paul Jones](/_next/image?url=https%3A%2F%2Fassets.basehub.com%2Fe0b5701f%2F6599306507912123f90f150a8bfaaf6c%2Fscreenshot-2026-01-28-at-10.53.16-am.png%3Fwidth%3D100%26height%3D100%26quality%3D100&w=96&q=75) Paul JonesHead of Growth at Classet ](/blog/authors/paul-jones) September 8, 2026 Skilled Trades, Guides & Insights The AI data center boom has a bottleneck, and it is human: the people who install the switchgear, pipe the chilled water, and run the hall once it opens. This page is the running tally of what the data center labor shortage looks like in 2026, sectioned by trade, with a source on every number. We update it monthly as new data lands; the date at the top is the last revision. It is written for the general contractors, MEP subcontractors, and operators who feel the shortage as a schedule problem. If you are one of them, the last section is about what to do this quarter. If you are here to understand the numbers, start at the top. Quick answer Construction needs an estimated 349,000 net new workers in 2026 and 456,000 in 2027 (ABC), and about 41 percent of the current workforce is projected to retire by 2031 (NCCER). Data centers concentrate that shortage in electrical work, which is 45 to 70 percent of a build's cost (IBEW), with hundreds of electricians per site at peak. A one-month delay on a 60 MW facility costs about $14.2 million (STL Partners). On the operations side, 25 percent of data center staff get hired away each year (Kelly). The trades in shortest supply, in order: electricians, pipefitters and mechanical, HVAC, controls and commissioning, facilities technicians. ## The headline numbers Associated Builders and Contractors' January 2026 [workforce release](https://www.globenewswire.com/news-release/2026/01/15/3219391/0/en/abc-construction-industry-must-attract-349-000-workers-in-2026-despite-macroeconomic-headwinds.html) puts the industry's need at 349,000 net new workers in 2026 and 456,000 in 2027, on top of normal hiring. ABC's chief economist, Anirban Basu, singled out one trade: demand for electricians capable of precision wiring "has surged due to the rapid increase in data center construction." (ABC's January 2025 projection had put the 2026 figure at 499,000; the newer number supersedes it.) The pipeline behind those workers is aging out. NCCER's long-standing [estimate](https://www.nccer.org/newsroom/how-apprenticeships-empower-adult-learners-and-bridge-the-construction-workforce-gap/) is that roughly 41 percent of the current construction workforce will retire by 2031. On the electrical side specifically, Fortune's [March 2026 reporting](https://fortune.com/2026/03/02/ai-data-centers-electrician-shortage-gen-z-training-careers/) puts the national need at more than 300,000 new electricians over the next decade, with about 20,000 retiring every year and nearly 30 percent of union electricians between 50 and 70. Data centers sit on top of that shortage rather than beside it. ABC's July 2026 [Construction Backlog Indicator](https://www.tileletter.com/abcs-construction-backlog-indicator-plummets-in-july/) found the 12 percent of contractors working on data centers carrying 11.4 months of backlog against 7.5 months for everyone else. Basu's line: "The data center boom masks the depth of this weakness." The work is there. The crews are the constraint. 349K Net new construction workers needed in 2026 (ABC) 45–70% Share of a data center build that is electrical (IBEW) $14.2M Cost of one month of delay on a 60 MW facility (STL Partners) ## What a delay costs The reason the shortage shows up as a hiring emergency rather than a slow squeeze is the penalty clock. STL Partners [modeled](https://stlpartners.com/press/delays-in-data-centre-construction/) a 60 MW US facility and found each month of delay costs the developer about $14.2 million in lost lease revenue, cost overruns, and contractual penalties, dragging the project's IRR from 17.1 percent on time to 15.5 percent after one month and 12.6 percent after three. The GC and the MEP subs sit under liquidated damages clauses tied to that clock. When the electrical crew is 40 heads short in the rough-in phase, that is not an HR problem; it is a line item the owner can see. ## The shortage by trade **Electricians.** The center of it. Electrical work is 45 to 70 percent of a data center's construction budget, per the [IBEW](https://ibew.org/electrical_worker/the-data-center-surge-a-new-generation-of-ibew-jobs/), because a hyperscale campus is a power plant with servers attached: medium-voltage distribution, UPS systems, generator paralleling switchgear, busway, and commissioning. Sites need hundreds of electricians at peak; Data Center Frontier [profiled](https://www.datacenterfrontier.com/sponsored/article/55242648/views-from-the-ground-electrical-contractors-building-data-centers-weigh-in) a Loudoun County job with more than 250 electricians and 60 to 70 apprentices under one general foreman, and the IBEW cites a Frederick, Maryland project expecting 1,000 workers on site with peak "double that. Or triple." IBEW Local 26 in Northern Virginia has roughly doubled since 2018 to about 14,700 members and still cannot fill the calls. We wrote the hiring playbook for this trade in [how to hire data center electricians](/blog/how-to-hire-data-center-electricians). **Pipefitters and mechanical.** Chilled-water plants, liquid cooling loops, and the piping for CRAH units and heat rejection. As AI halls move to direct liquid cooling, mechanical scope grows and the pipefitters who can weld and pressure-test those loops are competing with semiconductor fabs and battery plants for the same people. Bloomberg's July 2026 [survey](https://www.insurancejournal.com/news/national/2026/07/08/876657.htm) of data center builders named pipefitters second after electricians on the shortage list. **HVAC technicians.** Installation during construction, then the operations side once the hall opens. HVAC mechanics are also the trade that the residential and commercial service market cannot spare, which is why data center wages pull them out of service trucks. **Controls and commissioning.** Building automation, BMS and EPMS integration, and the Level 1 to Level 5 commissioning that brings a hall online. The group is small in headcount and large in schedule risk, because a commissioning team short one controls technician can hold a finished hall out of service for weeks. **Facilities technicians.** The operations workforce. Kelly's [2026 Data Center Salary Guide](https://www.kellyservices.com/press-releases/kelly-releases-2026-data-center-salary-guide-highlighting-compensation-hiring-trends-driven-by-ai-acceleration) found 90 percent of operators calling staffing shortages a critical constraint, 25 percent of data center personnel hired away by competitors each year, and permanent employment heading toward 650,000 positions in 2026. Operators are opening halls faster than they can staff 24/7 rotations, which is its own post: [24/7 data center operations staffing](/blog/24-7-data-center-operations-staffing). ## Where the shortage is sharpest The five markets with the most construction are the five with the tightest labor. Northern Virginia held 4,040 megawatts at the end of 2025 with 0.5 percent vacancy, per [CBRE](https://www.cbre.com/press-releases/northern-virginia-extends-lead-as-largest-u-s-data-center-market-in-2025). Atlanta overtook it for capacity under construction in the first half of 2026 at 2,882 megawatts, per CBRE's [H1 2026 report](https://www.cbre.com/insights/books/north-america-data-center-trends-h1-2026). Texas has at least 142 data centers under construction, more than any state, per the [Texas Tribune](https://www.texastribune.org/2026/04/08/texas-data-centers-sales-tax-break-billion-dollars/), and North Texas alone needs an estimated 3,000 additional electricians by 2032. Phoenix and Columbus round out the list, each with hyperscale campuses competing against semiconductor fabs for the same pipefitters and electricians. Market-by-market detail is in [where data center construction hiring is happening](/blog/where-data-center-construction-hiring-is-happening-2026). ## How the industry is responding Building the workforce, because there is no one left to hire away. Meta committed $115 million to a five-week trades academy with a guaranteed job at the end, piloting in Columbus, Indianapolis, Houston, and Baton Rouge, per [Fortune](https://fortune.com/2026/06/10/meta-data-center-free-training-employment-blue-collar-trade-jobs/). Google put $15 million over three years into the IBEW's electrical training ALLIANCE in 2025 and added roughly $20 million more in June 2026, per the [IBEW](https://ibew.org/google-funding-means-more-jobs-training-for-ibew-members/). Microsoft's Datacenter Academy runs technician programs through more than 30 education partners. Contractors are doing the same at smaller scale: CEC Facilities Group in Texas runs its own registered apprenticeship as it grows from 2,200 toward 4,000 employees. All of it pays off in three to five years. The broader [skilled trades labor shortage](/blog/overcome-skilled-trades-labor-shortage) has been pushing employers toward pipeline thinking for a while; the data center boom made the timeline unforgiving. The post that started this series, on [why Big Tech is short on electricians](/blog/data-center-trades-shortage), covers the training programs in more depth. ## What it means for hiring this quarter The apprentices arrive in 2029. The rough-in phase starts in November. Between those two dates, the contractors and operators who staff their projects are the ones who treat every application as a race, because the electrician who applied tonight applied to two other sites too. In practice that means three things. Publish the whole offer: rate, hours by phase, per diem, differential, ramp end date. Open reqs a phase early and keep a bench warm between phases. And screen applicants the moment they apply, not when the recruiter's calendar clears. Our data across trades hiring shows 88 percent of candidates complete a phone screen within 20 minutes of applying when the call comes right away, and 55 percent of applications arrive after hours. That first conversation is what Joy does for data center contractors and operators; the mechanics, from license and medium-voltage questions to the ATS write-back, are on the [data center hiring page](/use-cases/data-centers). ## Common questions How big is the data center labor shortage in 2026? Construction as a whole needs 349,000 net new workers in 2026 and 456,000 in 2027 (ABC, January 2026), with about 41 percent of the workforce retiring by 2031 (NCCER). Data centers concentrate the shortage in electrical work, which is 45 to 70 percent of build cost. Contractors on data center work carry 11.4 months of backlog versus 7.5 for others (ABC, July 2026), and 90 percent of operators call staffing a critical constraint (Kelly, 2026). Which trades are shortest for data center construction? Electricians rank first by a wide margin, because the IBEW puts electrical work at 45 to 70 percent of a data center's construction budget and Associated Builders and Contractors CEO Michael Bellaman puts electrical at about half of all labor on these projects. Pipefitters and mechanical trades come second, installing the chilled-water loops and cooling systems that grow as AI halls shift to liquid cooling. HVAC technicians follow, then controls and commissioning specialists, who are small in number and large in schedule risk. Once a facility opens, facilities technicians for 24-hour operations become the constraint. Bloomberg's July 2026 survey of craft-labor providers named electricians, pipefitters, and site supervisors as the top three gaps, and Uptime Institute found electrical skills gaps rising 13 percentage points since 2023. Why is the AI data center boom short on electricians specifically? Because a hyperscale data center is mostly an electrical project with a roof on it. Medium-voltage distribution, UPS systems, generator paralleling switchgear, and busway all require licensed electricians, and sites run hundreds of them at peak. Meanwhile the workforce is aging out faster than apprenticeships backfill it: Fortune reports about 20,000 electricians retire each year against a need for more than 300,000 new ones this decade, and nearly 30 percent of union electricians are between 50 and 70. The training pipeline cannot compress, since a registered apprenticeship through the electrical training ALLIANCE requires 8,000 hours of supervised fieldwork over four to five years. Microsoft president Brad Smith named electricians, not chips or land, as the shortage constraining US data center expansion. What does a labor shortage cost a data center project? STL Partners models a one-month delay on a 60 MW facility at about $14.2 million in lost revenue, overruns, and penalties, with project IRR falling from 17.1 percent to 12.6 percent after three months. Contractors under liquidated damages clauses carry a share of that cost, which is why crew shortages become bid and schedule problems immediately. How are hyperscalers responding to the shortage? By funding training: Meta's $115 million five-week academy with guaranteed jobs, Google's $35 million-plus to the IBEW's training arm, Microsoft's Datacenter Academy through 30-plus education partners, and contractor apprenticeships like CEC University. These add workers in three to five years; they do not fill this year's rough-in phase. How can a contractor hire data center trades faster right now? Three actions work inside a single quarter. First, publish the full pay stack in the posting: hourly rate, expected weekly hours by phase, per diem or housing for travelers, shift differential, and the honest end date of the ramp, because electricians compare stacks rather than base rates. Second, open requisitions a phase ahead, since MEP rough-in headcount peaks four to six months after civil work begins. Third, screen applicants the day the application lands rather than at the next recruiter review; Classet data across trades hiring shows 55 percent of applications arrive outside business hours and 88 percent of candidates complete a phone screen within 20 minutes when the call comes immediately. AI phone screening handles that first conversation, and a person on the team still makes the hire. ## Key points - Construction needs 349,000 net new workers in 2026 and 456,000 in 2027 (ABC); 41 percent of the workforce retires by 2031 (NCCER). - Electrical is 45 to 70 percent of a data center build (IBEW), which is why electricians are the sharpest shortage, followed by pipefitters, HVAC, controls, and facilities techs. - A one-month delay on a 60 MW facility costs about $14.2 million (STL Partners); data center contractors carry 11.4 months of backlog versus 7.5 for others (ABC). - Operators lose 25 percent of staff to competitors annually (Kelly 2026). - Training investments from Meta, Google, and Microsoft pay off in years; hiring speed is the lever available this quarter. ## Next steps If a ramp or a new hall is waiting on crews, the fastest fix is the first conversation with each applicant.
