AI Data Centers Drive Demand for Skilled Insulators

As artificial intelligence accelerates demand for data storage and computing power, union leaders in the mechanical insulation sector say the result will be a major surge in construction work.

On the America’s Work Force Union Podcast, Pete Ielmini, Executive Director of the Mechanical Insulators Labor Management Cooperative Trust, outlined how data center expansion, power generation needs and the technical demands of chilled systems are creating a strong long-term case for recruiting and training more skilled insulators.

• AI growth is increasing demand for large-scale data centers, which rely heavily on mechanical insulation to protect chilled systems and prevent moisture damage.
• The same expansion is expected to drive new power generation projects, creating additional work across the union construction trades.
• Industry leaders say apprenticeship recruitment must be matched with long-term retention planning so workers entering the trades can build lasting careers.

How AI is increasing demand for data center construction

Artificial intelligence is often discussed as a force reshaping office work, software and communications. In the building trades, the rise of AI is helping fuel a wave of data center construction, and that growth is expected to create substantial demand for skilled union labor.

That was the central labor message from Pete Ielmini, Executive Director of the Mechanical Insulators LMCT, during a recent appearance on the America’s Work Force Union Podcast.

As AI systems process more information and businesses store more data, the need for physical storage capacity also grows. That means more large-scale data centers, greater utility demand, and more construction projects tied to cooling, energy and reliability.

Ielmini noted that data centers have been under construction for years, but the next phase will be larger, faster and more labor-intensive as AI adoption expands. The latest projects are major industrial facilities with strict performance requirements and no margin for operational failure.

Why mechanical insulation is critical in data centers

As Ielmini explained, for the Heat and Frost Insulators Union, the data center boom is an expanding work opportunity tied to the technical needs of the buildings themselves. Data centers depend on server environments that must be kept below ambient temperature, which places a premium on chilled systems and precise insulation work.

That is where mechanical insulation becomes essential. In these environments, insulation is not only about energy efficiency. It is also about condensation control. When chilled systems are not insulated correctly, moisture can form on the outside of pipes and equipment. In a data center, that risk carries serious consequences because water and sensitive electrical systems cannot coexist without danger.

Ielmini said cold applications require a higher level of craftsmanship than many standard hot applications, as the work must account for both temperature retention and moisture prevention. A failure in insulation performance can create operational risk inside a facility designed to run continuously.

This technical reality helps explain why data center construction is expected to generate significant work for trained insulators.

Why AI growth is also driving new power generation projects

The conversation continued with Ielmini explaining that the same AI-driven data center expansion will place heavier pressure on the power grid, which is already under strain in many parts of the country. Data centers require enormous amounts of electricity, and their growth is expected to spur additional investment in energy generation.

As more data centers come online, utilities, private developers and large energy users are likely to pursue new power generation capacity to support them. That could include a wide variety of facilities producing electricity, designed to directly serve high-demand users.

The result will be data centers with dedicated power sources. That approach reflects a broader industry concern: digital infrastructure cannot expand without the corresponding growth of energy infrastructure.

For union construction, that matters because power generation projects also require skilled trades labor, including mechanical insulation work. The result is a linked construction cycle in which AI demand supports both data center development and the energy systems needed to keep those facilities operating.

Apprenticeship recruitment is urgent for the insulation industry

If the forecast holds, more trained workers will be needed soon. Ielmini used the discussion to make a direct case for increased apprenticeship recruitment, arguing that the current conditions make this a strong moment for workers considering a career in the insulation trade.

Ielmini presented the apprenticeship model as a serious pathway to quality wages and stability. In the union structure, apprentices can receive training through the Local program while learning the craft, with relatively low upfront costs compared with many other career paths. For workers willing to bring discipline and a work ethic, the trade offers a route to strong wages and a durable skill set.

That message aligns with a wider push across the building trades. As major infrastructure and industrial projects expand, unions are working to recruit the next generation of skilled workers before labor shortages become more severe.

Why retention matters as much as recruitment in the building trades

Ielmini also made an important distinction that often gets lost in workforce conversations. Recruitment is not enough. If unions and contractors bring in new workers to meet immediate demand, they also need a plan to keep those workers employed after the current surge levels off.

He argued that contractors, unions and labor-management partners all have a role in the planning. The goal is not simply to fill jobs for a boom period. It is to build a workforce that can stay in the industry, move where needed and support future work across regions and sectors.

That is also where union labor holds a structural advantage. Organized trades can move skilled workers across jurisdictions to meet demand, giving union contractors greater flexibility when large projects ramp up quickly. In a market shaped by labor shortages, that mobility can become a decisive strength.
