Data center construction: project reports, contractors and jobs

North America had more than 66 gigawatts of data center capacity under construction in August 2026, according to JLL. Seventy-seven percent of that capacity was being built outside the traditional core markets.^[7] The power has to be generated and delivered. The buildings have to be wired, cooled, piped, tested, commissioned, and maintained.

Electricians, plumbers, pipefitters, HVAC and refrigeration technicians, welders, equipment operators, fiber technicians, and licensed contractors do this work.

Those trades install and maintain the systems behind a data center. Their availability can affect project schedules and costs when several owners need the same workers.

Echelon tracks public license records and keeps dated snapshots. This article introduces the Wednesday series on the people and companies building data centers, power systems, factories, and other large projects.

The short answer

Is there a skilled-trade labor shortage affecting AI data center construction?

Yes, but a national headcount cannot tell a developer whether workers are available for one project. The answer depends on the trade, market, schedule, and experience required. General construction labor can be available while licensed electricians or controls technicians are scarce.

How many additional workers could the AI buildout require?

A September 2025 CSIS model put additional skilled-trade demand for generative AI infrastructure at about 74,000 to more than 140,000 positions by 2030, depending on the buildout. It included 19,000 to 37,000 electricians and 12,000 to 25,000 HVAC pipefitters.^[1]

What does Echelon currently measure?

The August 17, 2026 baseline counted 258,353 active electrical, plumbing, and HVAC credentials in the covered states and tiers. That included 163,103 electrical, 61,388 plumbing, and 33,862 HVAC credentials.

These are credentials, not 258,353 unique workers. They do not prove that a worker is employed, available, willing to travel, or qualified for a data center assignment.

The numbers that define the problem

National totals can hide a local shortage. A Minnesota credential does not fill a West Texas job. Residential electrical experience does not automatically qualify someone for medium-voltage work or data center commissioning. Apprentices also need supervision and time in training before they can take on journey-level work.

The relevant question is whether qualified people can work on this project during its construction window while other projects draw from the same market.

Check the required trades, location, schedule, and competing projects before calling a market short of workers.

AI is becoming a physical construction industry

AI infrastructure needs more than chips and utility power. Workers must connect that power to a working server hall.

A large data center needs substations, backup power, distribution, cooling, piping, controls, fire protection, fiber, security, and commissioning. Each system has its own work sequence, labor needs, and inspection rules.

The scale of the electrical load explains why this matters. The Department of Energy reported that data centers consumed about 4.4 percent of U.S. electricity in 2023. DOE projected that share could reach 6.7 to 12 percent by 2028, with total consumption rising from 176 terawatt-hours in 2023 to between 325 and 580 terawatt-hours in 2028.^[5]

The labor demand extends beyond the data center. Power plants, lines, substations, and equipment factories need skilled workers too. An electrician may be assigned to a hospital, battery plant, utility upgrade, or semiconductor factory instead of an AI campus.

McKinsey projected more than $250 billion in data center mechanical and electrical procurement and installation spending by 2030. Money can buy equipment, but training hours, licensing, and field experience take time.^[12]

Why the national workforce statistics do not answer the local question

The Bureau of Labor Statistics provides the best broad view of U.S. occupations. It counted 818,700 electrician jobs in 2024 and projected 9 percent growth from 2024 to 2034. BLS also projected 81,000 electrician openings a year, with many caused by retirement, occupational transfers, and other exits from the labor force.^[2]

For plumbers, pipefitters, and steamfitters, BLS projected 44,000 annual openings and 4 percent employment growth.^[3] For HVAC and refrigeration mechanics and installers, it projected 40,100 annual openings and 8 percent growth.^[4]

Those figures describe national job openings and growth. They cannot show how many people can take one data center assignment.

Five gaps separate a national occupational estimate from actual project capacity:

1. Geography. Construction labor markets are local until travel becomes economical. Per diem, overtime, housing, licensing, and schedule length determine whether workers move.
2. Licensing. States classify electricians, plumbers, HVAC workers, contractors, and qualifiers differently. Reciprocity ranges from useful to nonexistent.
3. Skill. A license establishes a legal credential. It does not establish medium-voltage, controls, clean-room, industrial refrigeration, liquid-cooling, or commissioning experience.
4. Availability. An employed worker is not spare capacity. A license database does not reveal current assignments, overtime, backlog, or willingness to travel.
5. Timing. Two viable projects can become a labor bottleneck when their peak electrical or mechanical schedules overlap.

There is no single worker gap that fits every site. Shortages depend on the trade, market, and construction schedule.

What Echelon’s license database sees

Licensing records show active credentials, classifications, status, and recorded locations. Some states also identify business affiliations and changes between snapshots.

Echelon’s first covered baseline contains:

The first electrical worker-tier panel covers Colorado, Idaho, Kentucky, Minnesota, Oklahoma, Texas, Virginia, and Wisconsin. Plumbing covers Colorado, Idaho, Kentucky, Minnesota, Oklahoma, Rhode Island, and Wisconsin. HVAC covers Idaho, Kentucky, and Oklahoma.

California and Ohio are in Echelon’s database, but these tables count contractor licenses rather than apprentice, journeyman, and master worker tiers. California’s August 15 snapshot has 27,940 clear C-10 electrical contractor licenses, 17,381 C-36 plumbing licenses, and 11,470 C-20 HVAC licenses. Ohio has 3,504 active electrical contractor licenses, 2,740 plumbing, 2,641 HVAC, 866 hydronics, and 693 refrigeration licenses. Adding them to the worker panel would mix different kinds of credentials. Echelon measures contractor and qualifier capacity separately. California worker-level coverage would require Division of Labor Standards Enforcement electrician certification and trainee records. Ohio’s construction licensing board does not publish an equivalent statewide apprentice-to-master roster.

The underlying source observations range from July 31 through August 16, 2026. We aggregated the baseline on August 17.

The 258,353 figure counts credentials in the covered panels, not a national workforce.

One person can hold more than one credential. States also differ in whether they license individual workers, contractors, or qualifying people. HVAC rules can be statewide or partly local.

Each release needs to state its coverage and counting limits alongside its totals.

What license records can tell us

A license record is not a worker-availability record. It is still useful.

Repeated snapshots can show:

• New apprentice registrations
• New journeyman and master credentials
• Renewals, lapses, and reinstatements
• Contractor entry and exit
• Qualifier movement between businesses
• Geographic expansion into another state
• Concentration of scarce qualifying credentials
• The time required for a new cohort to move through the licensing structure

Comparing snapshots can reveal changes worth investigating. Apprentice growth without similar journey-level growth may leave a near-term gap. Concentrated master credentials may leave a market dependent on a few contractors. Flat license counts alongside more project starts may add wage and schedule pressure. None of these patterns alone proves a shortage.

None of those signals confirms that a shortage caused a delayed project. They identify where to look before the delay becomes public.

The apprentice pipeline cannot solve a 2027 deadline by itself

Apprenticeships matter because licensed trades cannot expand without new entrants. They also take time.

In its high-case scenario, CSIS estimated roughly 37,000 additional electricians and 25,000 HVAC pipefitters by 2030. It recommended expanding registered apprenticeships in priority trades by 50 percent.^[1]

Google has begun funding that pipeline. In 2025, the company announced support for an electrical training effort intended to reach 100,000 electrical workers and train 30,000 new apprentices. The program aims to increase the electrical workforce pipeline by 70 percent over five years.^[8] In June 2026, Google expanded its skilled-trades commitment to $50 million, with a stated goal of helping train more than 300,000 workers through unions and trade associations.^[9]

Meta and CBRE launched a separate multiyear program in April 2026 to recruit and train thousands of fiber technicians for U.S. data center construction.^[10] The federal AI Action Plan also called for initiatives to increase high-demand occupations such as electricians and HVAC technicians while accelerating data center and semiconductor-fab development.^[11]

The training programs show that buyers are investing in future labor supply. They do not show that workers are available for current projects.

Someone starting an apprenticeship in 2026 will not finish the required hours in time to serve as an experienced journey-level worker on a 2027 schedule. Instructors, completion rates, work hours, and supervision rules all affect how many new workers can qualify.

Near-term projects will still rely on the existing workforce, travel labor, overtime, prefabrication, schedule sequencing, and competition among contractors.

The bottleneck will move

Power may be the first obstacle. After a developer secures it, equipment can delay construction. Once the equipment arrives, qualified people still have to install and test it.

Labor shortages rarely stop every project at once. They change the order of completion.

Large owners can pay travel packages, lock in contractors early, standardize designs, and secure manufacturing capacity. Their best response is to reserve labor before the market tightens further. That response makes labor less available to smaller projects, municipal work, hospitals, manufacturers, and local contractors.

Contractors may recruit across state lines, sponsor apprentices, use prefabricated assemblies, or buy firms with licenses and customer relationships. They still need enough supervisors and field crews for the work they accept.

The pressure will not stay inside data centers. It will move through every market that shares the same electricians, pipefitters, HVAC technicians, and equipment.

What this Wednesday series will measure

The Echelon Infrastructure Workforce Report will publish every Wednesday.

We will distinguish changes in long-term labor capacity from weekly changes. Government rosters, apprentice counts, BLS employment data, and project news update on different schedules.

The series will examine five questions:

1. Is the licensed workforce growing?

We will track active credentials by trade and level, then distinguish apprentice formation from journey-level and master capacity.

2. Where is demand arriving?

We will map data centers, power infrastructure, semiconductor plants, advanced manufacturing, and other projects that compete for the same workers.

3. When will projects collide?

A market can absorb one large project and still fail under three overlapping schedules. Timing matters as much as announced capital.

4. Which credentials and contractors are hard to replace?

Qualifier concentration, specialty classifications, reciprocity barriers, and contractor control can turn a modest headcount issue into a serious execution risk.

5. What changed this week?

New licenses, lapses, reinstatements, contractor entry, qualifier movement, project milestones, and schedule changes will form the weekly pulse.

Echelon will consider a capacity index after it has enough history to set a baseline and test the weighting. The first observation alone cannot establish a normal level.

What buyers should watch now

Developers, contractors, utilities, investors, economic-development groups, and equipment suppliers should watch the same early indicators:

• Apprentice growth without matching journeyman growth
• Flat active-license counts during accelerating project starts
• Multiple projects entering electrical or mechanical peak at the same time
• Rising dependence on a small number of master or qualifier licenses
• Interstate expansion by large contractors
• Increased use of travel labor, overtime, and per diem
• Project announcements in markets without an established industrial-trades base
• Training announcements that begin after the construction schedule already needs workers

No single signal proves a market is constrained. Several moving in the same direction deserve attention.

The finding to carry forward

Data center construction also competes with grid upgrades, factories, and existing building work for the same trades.

The country is trying to add tens of gigawatts of data center capacity while replacing workers who retire, expanding the grid, building factories, and maintaining everything already in service. The same licensed trades sit underneath all of it.

Echelon’s initial database is a defined set of dated license records. It does not count every skilled worker in America, but later snapshots can be compared within the stated coverage.

Every Wednesday, we will show what changed.

Methodology and limitations

Echelon assembled the baseline from state records for covered electrical, plumbing, and HVAC licenses. We counted records with active status under each state’s rules. We mapped apprentice, journeyman, and master tiers only where the source supported that mapping.

The unit is an active credential or registration, not necessarily a unique worker. It does not show employment, availability, or data center experience.

State systems use incompatible classifications and publication schedules. Coverage is incomplete and uneven by trade. Counts may include cross-state and cross-tier duplication. We will preserve source-native classifications, snapshot dates, and coverage disclosures as the system expands.

External demand estimates model scenarios or broad job markets, not verified data center vacancies. To assess one project, we need its location, schedule, trades, likelihood, contractor commitments, and whether workers can travel or obtain the needed credentials.
