Artificial intelligence is reshaping industries worldwide, and one of the most visible physical consequences is the explosive growth in data center construction. As AI workloads demand exponentially more computing power and storage, technology companies are racing to build facilities that can house the required infrastructure. Precast concrete has emerged as a preferred building material for these projects, offering the speed, structural capacity, and reliability that data center owners need. This article examines how precast concrete systems are meeting the challenges of AI-driven data center construction. For building professionals looking to understand the broader landscape of concrete methods and materials, the shift toward precast solutions represents a significant evolution in how mission-critical facilities are delivered.
The AI-Driven Surge in Data Center Construction
The scale of data center demand driven by artificial intelligence is unlike anything the construction industry has seen before. A McKinsey and Company report forecasts 10 percent annual data center growth until 2030, and many industry observers consider this estimate conservative. Microsoft alone operates 150 data centers worldwide, and the numbers continue growing.
To understand the scale, consider the computing requirements behind AI. Goldman Sachs found that a single ChatGPT query requires 10 times as much electricity as a Google search. Every AI model training run, every inference request, and every data pipeline demands physical infrastructure: servers, networking equipment, cooling systems, and the buildings that house them all.
Roksana (Roxy) Taghizadeh, associate principal with AG&E, a structural engineering firm based in Dallas, Texas, and engineer of record for 50 to 80 data centers a year, confirms the intensity of current demand. Things are not slowing down, she says. There is huge demand for us to churn these out as quickly as possible to meet expedited construction schedules. This pressure has forced project teams to rethink traditional approaches and look for building systems that can be manufactured in parallel with site preparation.
Why Precast Concrete Is the Material of Choice for Data Centers
Precast concrete offers a combination of attributes that align closely with data center requirements. Components are manufactured off-site in controlled factory environments, then delivered for rapid erection. This approach decouples fabrication from site conditions and allows construction to proceed on multiple fronts simultaneously.
Off-Site Fabrication and Accelerated Schedules
Since precast concrete components are manufactured off-site, they can be procured and fabricated before the site is disturbed, explains Corey Greika, vice president and general manager of Coreslab Structures in Indianapolis. The precast can be scheduled to be erected at a specific time once the foundations are in place.
Once erection begins, the process is extremely fast. Insulated precast concrete wall panels arrive with all elements of a finished wall system built in, including finished surfaces, air barriers, and vapor barriers. This integration eliminates multiple field operations that would otherwise consume time. Many precast producers have installed new production lines specifically to increase capacity for data center components, and multiple manufacturing facilities can be coordinated to meet aggressive schedules.
Michael Lyons, vice president and mission-critical practice leader at HKS, stresses the importance of early collaboration. Early collaboration allows us to integrate precast concrete solutions during the design phase, enabling fabrication of panels concurrently with site preparation. Precast also means fewer trades on site, streamlining construction and minimizing delays.
Structural Performance for Heavy Equipment Loads
Data centers place extraordinary demands on floor structures. Over the last decade, average rack power densities have nearly quintupled to 10 kW, and self-weight has doubled to about 1,814 kg (4,000 lb) per rack. In five years, average power densities are expected to quintuple again to approximately 50 kW per rack, with weights potentially doubling. EnCon Design has observed suspended loads exponentially doubling and roof live loads tripling from 2010 to 2024.
To accommodate these increasing loads, many precast producers have invested in deep-stem double-tees. These sections, nearly standardized at 4 m (12 ft) wide and 12 m (40 ft) deep, provide the structural capacity needed to support dense rack configurations while maintaining the long, clear spans that allow flexible equipment layouts. As floor-to-floor heights rise to approximately 9 m (30 ft) to accommodate additional electrical connections, precast concrete delivers the necessary strength at scale.
Fire Resistance and Thermal Efficiency
Precast concrete provides inherent fire resistance ratings of two or three hours, which is critical for mission-critical facilities where downtime is unacceptable. The thermal mass of concrete helps regulate interior temperatures, reducing cooling loads. Insulated wall panel construction further enhances thermal performance, making precast an excellent choice for temperature-sensitive data center environments.
For projects focused on envelope performance, understanding how precast integrates with high-performance building envelopes is essential for maximizing energy efficiency over the facility’s lifespan.
Total Precast Structures: A Complete Building Solution
Data center designs are moving from sprawling single-story warehouses toward compact multistory buildings. Jason Lien, executive vice president at EnCon United Company, notes this shift is driven by efforts to conserve fiber optic cable and address latency issues between AI servers. At these increased heights, total precast concrete structures become more attractive in terms of cost savings and delivery impact.
A total precast structure uses precast, prestressed concrete for the core and shell above grade. This approach offers advantages that directly benefit data center construction.
Vibration Control and Long Spans
Precast concrete offers inherent vibration absorption critical for data centers housing sensitive electronic equipment. The ability to support long, clear spans is valuable for organizing various rack layouts with minimal disruption from columns or intermediate supports. This flexibility allows operators to reconfigure floor plans as technology evolves.
The controlled access zone (CAZ) approach used in total precast construction allows different areas of a building to be at different completion stages simultaneously. While one section is under active construction, another can undergo MEP work, and a third can be ready for equipment installation. This condenses the functional ROI schedule while maintaining structural integrity.
Quality Assurance Through PCI Certification
Precast concrete producers certified by the Precast/Prestressed Concrete Institute (PCI) adhere to rigorous quality assurance and quality control standards. Quality staff inspect products and hardware before concrete is placed and evaluate products after form removal. Concrete is sampled and tested at regular intervals by certified technicians.
PCI-certified erectors perform installation, ensuring details and connections are installed according to specifications. An engineered installation plan is developed based on staged loading and unloading, often required during construction. This level of assurance gives owners confidence that their facilities will perform as designed.
Adaptability for Future Needs
Precast concrete structures are inherently adaptable. The predominant use of bonded prestress strand reinforcement means strands can often be cut while still providing reinforcement benefits. Prestressed concrete stemmed floor systems allow significant flexibility for future floor openings. Many precast wall panels are designed and reinforced for future openings, with reveals showing where cuts can be made.
This matters because data centers undergo technology refreshes every three to five years. The ability to modify floor layouts, create new openings, or reinforce specific areas directly affects the facility’s useful life. Owners can plan for multiple equipment generations without reconstructing the building shell.
Sustainability and Resilience Advantages
Sustainability is an increasingly important consideration for data center owners. The combination of reduced embodied carbon, improved resilience, and long service life makes precast concrete an environmentally responsible choice.
Lower Embodied Carbon Through Optimized Mix Designs
Allan Bedwell, chief sustainability officer at Clark Pacific, notes that data center owners are driving hard to reduce embodied carbon. His company focuses on concrete mixes that use less cement and optimizes designs to minimize concrete and steel quantities. Clark Pacific is releasing an ASTM-verified environmental product declaration for a data center and a third-party lifecycle analysis comparing precast concrete to steel alternatives.
Total precast structures can reduce overall material usage through precast concrete’s inherent strength and fire resistance. Fewer columns and reduced composite topping for floors lower embodied carbon and reduce on-site labor. For professionals interested in the broader picture, understanding low-carbon concrete mixes provides valuable context for material specification.
Seismic and Wind Resilience
A recent example is a three-story, 65,032 m2 (700,000 sf) total precast concrete data center in the Phoenix metropolitan area. This facility received the U.S. Resiliency Council’s first Platinum Seismic Rating and Platinum Wind Rating. These ratings indicate negligible damage and repair cost expected following a major seismic or wind event, with functional recovery within days.
