You know that something extraordinary is happening on the outskirts of Abilene, in the Big Country part of Texas, even before you arrive. By 6 a.m., a line of cars stretches a mile from the highway to where thousands of workers are building one of the biggest data center sites in the world.āÆĀ
Preston Williams of DPR Construction, the projectās general contractor, is part of the team building the Abilene data center. Its size is staggering. One of the largest such centers in the U.S., and possibly the world, the site will span 4 million square feet, roughly 70 football fields, and include eight buildings that will each house up to 50,000 Nvidia artificial intelligence (AI) chips. The centerās power needs will approach 1.2 gigawatts, rivalling the output of a nuclear plant.āÆThe center will be part of the $500 billion Stargate program that will provide the massive infrastructure needed to power the boom in AI. āIt really is a place to test how to plan a job correctly, because you have to have some way to organize the madness,ā Williams says.Ā
Williams sat down with the Bentley Horizons podcast to talk about the massive project, in an episode thatās all about hyperscale data centersāabout what it takes to plan, build, power, cool, and secure megaprojects that rival the size of New Yorkās Central Park.Ā
The podcastās latest episode also hosts David Lawson of Assystem, one of the worldās top nuclear engineering firms, Dara Khera and Sukshma Paranjpe of the startup Bohm, and David Ayeni, global director of Infrastructure Cloud Partner Experience at Bentley Systems. You can read about more of David’s work on the blog. Join the conversation below:Ā
A Soaring AI Workload
Demand for AI infrastructure, which is already growing at a rapid clip, is set to rise further, with some analysts predicting that the workload of data centers will triple in the next five years alone. For these massive projects, 4D planning, which links 3D models to construction schedules, can be key. It allows users to design and visualize the project and get maximum stakeholder buy-in before any concrete is poured. Williams notes the advantages of using the 4D planning capabilities in Bentleyās Synchro platform, particularly when so many workers at the Texas site are new hires. āThe model paints a picture of the scope of work theyāre going to install even if theyāve not built it before,ā he said.Ā
The Henry Ford Approach to Nuclear Power and Data
Another challenge is powering the power-hungry centers. Thatās where nuclear power and small modular nuclear reactors, or SMRs, come in, says Assystemās Lawson.āÆHe says SMRsāwhich are smaller than traditional nuclear power plants and can be partially built from prefabricated componentsāoffer an important advantage in the standardization and modularity of their designs. Lawson calls it āthe Henry Ford approach to nuclear power plants.ā It allows them to be built faster and more cheaply compared to conventional reactors.Ā Ā
āWhat weāre seeing is a huge demand for reliable baseload power,ā where the reliability of the power is 95% plus, Lawson says. āData [centers] rely on continuous power, something which solar and windāat least in the U.K.ācanāt quite make it. They need the baseload power, and in reality, in the fight against climate change, only nuclear can provide that kind of power level.āĀ
Trusting Trustlessness
The demand for hyperscale data centers is also creating the market conditions where new alliances and partnerships are happening fast. As head of Infrastructure Cloud Partner Experience, Ayeni is taking the lead in Bentleyās partner experience. āNo one company can solve the problem of infrastructure projects,ā Ayeni tells the podcast. āMy role is all about finding best-in-breed partners all through the infrastructure lifecycle.āāÆĀ
One of those new partners is innovative construction startup Bohm. Khera, the companyās CEO, tells the podcast that outside of a few lucky hydropower-rich places like Scandinavia or Quebec, nuclear is the ideal, most carbon-neutral power source for data centers.Ā
SMRs, of course, need to be deployed with strict security, safety, and compliance with regulations. Here, Khera says ātrustlessnessāāa core concept in blockchain technology and cryptocurrenciesāwould be key.Ā
āWhen we say ātrustlessness,ā we mean your data doesnāt go to a centralized entity,ā Khera says. āBy distributing this to thousands of different nodes, it effectively becomes tamperproof, like Bitcoin.āĀ
