The Numbers Tell a Clear Story
The Associated Builders and Contractors (ABC) released its February 2026 Construction Backlog Indicator, and the headline number of 8.1 months looks almost boring. Up a tenth of a month from January. Down two tenths from a year ago. Business as usual.
But dig into the segment data and you see something much more significant. Contractors with data center projects on their books carry 11.2 months of backlog. Everyone else sits at 7.6 months. That is a 47% gap, and it has been getting wider since mid-2025.
This is not a blip. It is a structural realignment of the construction economy around a single sector: the $700 billion data center buildout being driven by hyperscalers like Amazon, Google, Microsoft, and Meta. These companies are pouring capital into compute infrastructure at a pace the industry has never seen. And the contractors positioned to capture that work are pulling away from everyone else.
For construction business owners running firms in the $1M to $50M range, this data should prompt a serious strategic question: are you on the right side of this divide, and if not, what does it take to get there?
Where the Work Is Concentrated
The geographic story is just as lopsided. The Middle States region is the only area in the country where backlog is higher than it was a year ago. That region includes Virginia (home to “Data Center Alley” in Northern Virginia, the largest concentration of data centers on the planet), Ohio (where Intel’s $20 billion fab is driving ancillary data center development), and Pennsylvania.
The Southern region and Western region are both showing year-over-year backlog declines, which seems counterintuitive given the amount of construction activity in states like Texas and Arizona. But those markets are experiencing a different problem: residential and light commercial work is softening while heavy civil and industrial work requires scale that most mid-market contractors do not have.
The Northeast is flat. The Midwest outside of the Middle States is struggling with agricultural infrastructure demand that has not materialized as expected.
What this means: if you are a contractor in Virginia, Ohio, Pennsylvania, or the broader data center corridor, you are in the right geography. If you are anywhere else, you need to think about whether your current market mix can sustain growth.
The Size Gap Is Just as Real
ABC’s data also reveals a significant gap by company size. Large contractors with annual revenue above $100M average 10.4 months of backlog. Mid-market firms between $30M and $100M sit at 8.2 months. And firms under $30M are at 6.8 months.
This is not surprising. Data center projects are massive, multi-year engagements that require bonding capacity, safety track records, and workforce depth that most smaller firms cannot demonstrate on their own. The typical hyperscaler data center campus involves $500M to $2B in total construction value, with individual buildings running $200M to $500M each.
But here is the opening for mid-market contractors: the GCs winning these projects need subcontractors. A lot of them. A single data center building requires specialized electrical work (medium and high voltage), mechanical systems (cooling is the most critical building system), concrete and structural steel, fire protection, and low-voltage cabling. The prime contractors cannot self-perform all of this work.
The question is whether your firm has the right credentials, relationships, and capacity to capture subcontracting opportunities on these projects.
What Trades Are in Highest Demand
Not every trade benefits equally from the data center boom. Based on project labor breakdowns and hiring data from the major GCs in this space, here is where the demand is strongest:
Electrical contractors are the most sought-after subcontractors on data center projects. These facilities are essentially power distribution systems with a building around them. A single data center can draw 30 to 100 megawatts of power, requiring medium-voltage switchgear, backup generator systems, uninterruptible power supplies, and complex distribution networks. Electrical work typically represents 35 to 40% of total data center construction cost.
Mechanical and HVAC contractors are the second most in-demand trade. Cooling systems account for 30 to 40% of a data center’s operating cost, and the industry is moving rapidly toward liquid cooling, direct-to-chip cooling, and rear-door heat exchangers. Contractors who understand these emerging cooling technologies have a significant advantage over those who only know traditional DX or chilled water systems.
Concrete and structural contractors are needed for the massive slab-on-grade foundations these buildings require. Data center floors must support server rack loads of 150 to 250 pounds per square foot, compared to typical commercial office loads of 50 to 80 PSF. The structural requirements are more demanding than most commercial construction.
Fire protection contractors work on specialized clean agent suppression systems (not standard wet sprinkler) designed to protect servers without causing water damage. This is niche work that commands premium pricing.
Low-voltage and cabling contractors handle the structured cabling, fiber optic backbone, and connectivity infrastructure. This is high-volume, repetitive work that mid-market firms can scale into relatively quickly.
Which GCs Control the Data Center Pipeline
If you want data center subcontracting work, you need to know who controls the pipeline. The top general contractors and construction managers in data center construction include:
Turner Construction is the largest data center builder in the United States by volume. They manage multiple hyperscaler relationships and have a robust subcontractor prequalification process. Getting into Turner’s qualified subcontractor database is the single most impactful step a mid-market firm can take.
DPR Construction specializes in technically complex buildings and has a significant data center portfolio, particularly on the West Coast and in the Midwest.
Holder Construction has deep relationships with Microsoft and Google and is expanding its data center team aggressively.
Fortis Construction focuses on the Pacific Northwest data center market.
Hensel Phelps, Balfour Beatty, and JE Dunn all have growing data center practices.
The pattern across all of these GCs: they prequalify subcontractors based on safety record (EMR below 0.80 is typically the minimum), financial capacity (bonding), workforce depth (can you staff a crew of 20 to 50 for 12 or more months), and relevant experience.
How To Break Into Data Center Subcontracting
-
Get your safety numbers right. Your Experience Modification Rate (EMR) needs to be below 0.80, and ideally below 0.70. If your EMR is above 1.0, you will not get past the prequalification stage with any major data center GC. Invest in a formal safety program, get OSHA 30 for all supervisors, and document everything. This is a 12 to 18-month process to move the needle if your current numbers are average.
-
Apply for prequalification with the top 5 GCs. Start with Turner, DPR, and Holder. Each has an online prequalification portal. Fill it out completely. Provide three years of financial statements, your insurance certificates, your EMR history, and your project history. Do not wait for a specific project to apply. Get in the database now.
-
Build data center-specific credentials. Get your team trained on data center-specific safety protocols, including arc flash awareness, energized work permits, and clean room procedures. If you are an electrical contractor, pursue NETA certification for your testing technicians. If you are mechanical, get ASHRAE certifications related to data center cooling.
-
Start small and local. You do not need to chase a $50M subcontract on a hyperscaler campus as your first data center job. Look for smaller edge data centers (5 to 10MW facilities) being built by colocation providers like Equinix, Digital Realty, or QTS. These projects are typically $20M to $80M total, with subcontract packages in the $1M to $10M range. More manageable for a mid-market firm.
-
Invest in workforce depth. Data center GCs need subs who can commit 20 to 50 workers for 12 or more months straight. If you are running a 15-person crew and borrowing labor for big jobs, you are not ready. Build your permanent headcount or establish reliable labor partnerships before you bid.
-
Network at the right events. The Data Center World conference, AFCOM events, and the 7x24 Exchange are where data center owners, designers, and GCs gather. These are not typical construction trade shows. They are technology-focused events where you can build relationships with the people making subcontractor selection decisions.
The Risk of Staying Put
The data center boom will not last forever at this intensity. Hyperscaler capital expenditure plans currently extend through 2028 to 2030, which gives contractors a three to four-year window to establish themselves in this market. After that, the buildout pace will likely moderate as the first wave of facilities reaches completion.
But the larger risk is more immediate: if your backlog is sitting at 7.6 months or less and you are dependent on traditional commercial or residential sectors, your margin for error is razor thin. One lost bid, one delayed project, or one slow-paying client can create a cash flow crisis that threatens your entire operation.
The contractors who are thriving right now share three characteristics: they are positioned in high-demand sectors, they have strong safety and financial credentials, and they have invested in workforce capacity before they needed it. Those are not things you can fix overnight, but they are things you can start working on today.
Frequently Asked Questions
What is driving the data center construction boom?
The explosive growth of artificial intelligence, cloud computing, and digital services is driving unprecedented demand for data center capacity. Hyperscalers like Amazon Web Services, Google Cloud, Microsoft Azure, and Meta are spending tens of billions of dollars annually on new data center construction. AI workloads in particular require massive compute power and specialized cooling infrastructure, which has accelerated the pace of new facility development. Industry analysts project data center construction spending will exceed $100 billion annually through 2028.
Can a small contractor realistically compete for data center work?
Yes, but not as a prime contractor. Mid-market contractors in the $5M to $50M revenue range can compete for subcontracting packages on data center projects. The key requirements are a strong safety record (EMR below 0.80), financial capacity to carry 60 to 90-day payment cycles, workforce depth to staff 20 or more workers consistently, and trade-specific certifications relevant to data center construction. Starting with smaller edge data center projects from colocation providers is the best entry point before pursuing hyperscaler campus work.
Which regions have the most data center construction activity?
Northern Virginia remains the largest data center market globally, with Ashburn and Loudoun County hosting the highest concentration of facilities. Other major markets include Dallas-Fort Worth, Phoenix, Columbus (Ohio), Chicago, and Northern California. Emerging markets with significant growth include Indiana, Georgia, and the Carolinas. The Middle States region is the only area showing year-over-year backlog growth specifically because of data center concentration.
How long will the data center construction boom last?
Current hyperscaler capital expenditure plans extend through 2028 to 2030, with some projections pushing to 2032. The pace of AI adoption, which is the primary driver of new capacity demand, shows no signs of slowing. However, the construction intensity will likely moderate after the initial wave of facilities is complete, shifting from greenfield construction to expansions, retrofits, and technology upgrades. Contractors should treat the current window as a three to five-year opportunity to establish themselves in the sector.
What certifications help contractors win data center subcontracting work?
For electrical contractors: NETA certification for acceptance testing, NFPA 70E arc flash training, and medium-voltage switchgear experience are critical differentiators. For mechanical contractors: ASHRAE data center cooling certifications and experience with liquid cooling systems give a competitive edge. For all trades: OSHA 30 for supervisors, site-specific safety orientation programs, and documentation of zero-incident track records on previous projects are table stakes for prequalification with the major GCs.
