Data center construction is the engineering, fabrication, and field assembly of the buildings, power systems, cooling, and structural infrastructure that house computing equipment at scale. It has become one of the fastest-moving segments of American industrial construction. U.S. data centers already consumed about 4.4 percent of the country’s electricity in 2023, and the Department of Energy projects that share could climb to between 6.7 and 12 percent by 2028. That demand does not get met with drywall and a raised floor. It gets met with heavy steel, high-capacity mechanical systems, precise equipment setting, and schedules measured in weeks, not quarters.
This guide breaks down what data center construction actually involves, why the work is different from a standard commercial build, and how owners and general contractors evaluate a fabrication and field partner that can keep a mission-critical project on track.
Key Takeaways
- Data center construction blends structural steel, mechanical and process piping, precision equipment setting, cooling infrastructure, and civil work, usually on compressed, schedule-driven timelines.
- Power and heat are the core engineering challenges. A single NVIDIA GB200 NVL72 rack draws roughly 120 kilowatts and is liquid-cooled by design, which reshapes how mechanical systems are built.
- Demand is not slowing. The International Energy Agency projects global data center electricity use will more than double by 2030, and the U.S. Energy Information Administration forecasts the strongest four-year run in national power demand since 2000.
- Modular fabrication, building major assemblies in a controlled shop and installing them in the field, is one of the most effective ways to compress a data center schedule.
- The right partner self-performs across steel, mechanical, and civil scopes so coordination happens under one roof instead of across a dozen subcontractors.
What is data center construction?
Data center construction is the delivery of purpose-built facilities that power, cool, and physically protect servers, storage, and networking gear running around the clock. Unlike a warehouse or an office, a data center is defined by two engineering realities: it consumes enormous amounts of electricity, and it must reject the heat that electricity produces without interruption.
That makes the discipline far closer to industrial and energy construction than to conventional commercial building. The scope typically spans site civil work and foundations, structural steel, electrical distribution, mechanical and process piping for cooling, generator and switchgear setting, and protective coatings. Every one of those systems has to be installed to tight tolerances and commissioned as a coordinated whole, because a single point of failure can take a facility offline.
Why data center construction is accelerating across the United States
The pipeline of new data center projects is expanding because the computing behind artificial intelligence needs somewhere to live. The Department of Energy reported that U.S. data center electricity use rose from 58 terawatt-hours in 2014 to 176 terawatt-hours in 2023, and is projected to reach 325 to 580 terawatt-hours by 2028. The same analysis found that data center load growth has tripled over the past decade.
That surge is now visible in national grid forecasts. The U.S. Energy Information Administration expects electricity demand to grow about 1 percent in 2026 and 3 percent in 2027, the strongest four-year growth period since 2000, and it attributes the increase largely to large computing facilities. The trend is global as well. The International Energy Agency estimates data centers used 415 terawatt-hours of electricity worldwide in 2024 and will more than double that to roughly 945 terawatt-hours by 2030, with advanced economies absorbing more than 20 percent of that demand growth.

For contractors and facility owners, the takeaway is practical. New capacity has to be built quickly, and it has to be built by teams that understand power and heat, not just square footage.
Why data centers are not typical commercial builds
The defining difference is power density, and it is climbing fast. A modern AI compute rack packs far more electrical load into the same footprint than traditional IT gear. NVIDIA’s GB200 NVL72, for example, connects 36 Grace CPUs and 72 Blackwell GPUs in a fully liquid-cooled, rack-scale design that draws on the order of 120 kilowatts in a single rack. Air cooling alone cannot carry that heat load, which is why liquid cooling has moved from a niche option to a baseline requirement in high-density halls.
That single fact ripples through the entire build. Higher power density means larger electrical infrastructure, more generators and switchgear to set, and far more mechanical work: chilled water loops, coolant distribution units, pumps, and the process piping that ties them together. The structural system also has to carry heavier equipment and support overhead distribution. In short, the mechanical, piping, and structural scopes that define industrial construction are exactly the scopes a modern data center leans on hardest. This is why mechanical and process piping capability is central to delivering these facilities rather than an afterthought.
The core scopes of data center construction
A data center is only as reliable as the sum of its systems, and most of those systems are heavy, industrial, and interdependent. Below are the core self-perform scopes that keep a project moving and the reason each one matters.
| Scope | Why it matters on a data center project |
|---|---|
| Structural steel fabrication and erection | Frames the building and supports heavy mechanical and electrical equipment, cable trays, and overhead distribution |
| Mechanical and process piping | Carries chilled water, coolant, and utility services for the cooling systems that keep servers online |
| Precision equipment setting and millwright work | Places and aligns generators, switchgear, chillers, and pumps to exacting tolerances |
| Civil, earthwork, and foundations | Prepares the site and pours the foundations and pads that everything else is built on |
| Protective coatings | Extends the service life of steel and equipment in a facility expected to run for decades |
LMC delivers these scopes in-house. Certified welders and fabricators handle the structural steel and piping, licensed crane operators and certified millwrights set and align critical equipment, and NACE-certified painters and blasters apply protective coatings. Consolidating that range of work under one contractor removes the seams where schedules usually slip.
How modular fabrication compresses the schedule
Speed to power is the metric that matters most to a data center owner, and modular fabrication is one of the strongest levers for hitting it. Instead of assembling every system in the field, major components are built as modules in a controlled shop, then transported and installed on site. Shop fabrication runs in parallel with site work, keeps welding and assembly out of the weather, and improves quality control because it happens in a fixed, well-lit, tightly managed environment.
LMC builds modular data center skids and processing skids inside a 700,000 square foot fabrication facility in Dansville, New York, that sits on 88 acres with more than 300 pieces of owned equipment. Turnkey engineering, design, manufacturing, transportation, and on-site installation happen through one team, which is what allows on-site field crews and shop fabrication to work as a single, coordinated effort. For an owner racing to energize a facility, that combination of power generation and data center capability shortens the path from groundbreaking to commissioning.
The approach also scales. Modular skids can be replicated and added as a campus grows, so the same design and fabrication process that delivers the first phase supports the next one.
How to choose a data center construction partner
The best predictor of a smooth data center build is a partner who has done heavy, schedule-driven industrial work before. When evaluating a fabrication and field contractor, weigh a few specifics:
- Self-perform breadth. Can the contractor deliver steel, mechanical, piping, equipment setting, and civil work with its own workforce, or does it broker most of it out? In-house scope means tighter coordination and fewer handoffs.
- Fabrication capacity. A large, well-equipped shop lets a contractor build modules off-site and protect the schedule. Ask about facility size, equipment, and welding and fabrication certifications.
- Skilled, certified workforce. Certified welders, licensed crane operators, and certified millwrights are what turn a plan into a commissioned facility. LMC fields more than 350 skilled tradespeople across these disciplines.
- Safety record. Mission-critical clients hold high expectations for safety performance. A mature safety program is table stakes, not a bonus.
- Experience in power and energy work. Data centers borrow heavily from power generation and industrial process construction. A contractor with a track record in structural fabrication and energy infrastructure brings directly transferable expertise.
Frequently Asked Questions
How long does data center construction take?
Timelines vary widely with size, power capacity, and site conditions, but owners consistently push for the shortest possible path to energization. Modular fabrication, in which major assemblies are built off-site while site work proceeds, is one of the most reliable ways to shorten the overall schedule without cutting corners on quality.
Why do modern data centers require liquid cooling?
Power density has outrun the limits of air cooling. High-performance AI hardware such as NVIDIA’s GB200 NVL72 draws roughly 120 kilowatts per rack and is built as a liquid-cooled system. Removing that much heat reliably requires chilled water and coolant loops, which is why mechanical and process piping scopes are so significant on these projects.
What trades are most important on a data center build?
Structural steel, mechanical and process piping, precision equipment setting, and electrical distribution carry the heaviest load. Because these systems are interdependent, a contractor that self-performs across several of them can coordinate the work more tightly than a stack of separate specialty subcontractors.
Is data center demand expected to keep growing?
Yes. The International Energy Agency projects global data center electricity use will more than double by 2030, and the U.S. Energy Information Administration forecasts the strongest four-year stretch of national electricity demand growth since 2000, driven largely by data centers. That points to a sustained construction pipeline rather than a short-term spike.
