Mike Walsh, IMEG Senior Director of Industrial, joins this episode to discuss small modular reactors (SMRs) and their potential for becoming an integral source of power for manufacturers and industrial campuses.

SMRs typically produce 50 to 300 megawatts of power, unlike traditional nuclear plants that generate between 1,000 and 1,500 megawatts. Mike is quick to clarify, however, that the adjective “small” is relative in comparison to traditional reactors. “They’re not small—they’re just smaller,” he says of SMRs. “They’re still large, sophisticated facilities. But their modular construction changes everything.”

SMRs work on the same basic principle as traditional reactors: nuclear fission heats water into steam, which drives a turbine to produce electricity. Unlike traditional reactors, the reactor portion is manufactured within a factory—where conditions are controlled and quality assurance is consistent—and are then shipped to a location. They require significant real estate—typically 10 to 100 acres, but still far less than the 250 to 400 acres for a traditional nuclear plant.

Their smaller footprint makes SMRs particularly well suited for industrial campuses. And while roughly two-thirds of a traditional nuclear plant’s thermal energy is lost as waste heat, SMRs can capture and reuse that excess energy. “If we can use that heat for industrial processes or building systems, overall efficiency on an industrial site could reach 80 or 90 percent,” Mike says. The 24/7 on-site generation of power also will be highly beneficial to industries as the reliability and strain on the grid continue to worsen, energy costs rise, and owners begin to see high demand factors on utility bills.

With few new nuclear plants built in the U.S. since the 1970s, the path forward for SMRs is murky. “No one really knows yet how these will be regulated,” Mike says. “You can’t apply the same rules that were written for massive, one-of-a-kind nuclear facilities. This is new territory.”

Economics also is a factor. Early SMRs will be expensive, but Mike draws a parallel to renewable energy’s evolution. “Solar was once prohibitively costly too,” he says. “Then technology improved, production scaled, and prices fell. The same thing will happen here.”

The general perception of nuclear power will also need to be overcome. ”It's the not-in-my-backyard syndrome kind of thing,” Mike says. “There are reasons why nuclear accidents happened in the past, but it’s highly improbable that that would happen with these newer facilities and the way they have some passive ability, if they lost all power to the site, to still cool that reactor and not have a meltdown.

Despite the challenges, Mike believes nuclear power will be an essential part of a diversified energy mix of the future, which will also include wind, solar, hydro-electric, and, for some time at least, coal. “There are a lot of pieces of the puzzle for how we are going to create energy now and into the future.”

Several companies are now building various versions of SMRs. One of them, Kairos Power, is constructing a demonstration reactor in Tennessee; IMEG is collaborating with HDR on the project. The facility is expected to be online in 2027 and will provide essential data on performance, safety, and cost, laying the groundwork for future deployment.

Compared to traditional nuclear plants that take decades to bring online, Mike believes that the faster production and startup of SMRs will be key to addressing current and future energy needs. “SMRs are made to help with a problem we have right now, not a problem we're going to have in 30 years.”

This episode features IMEG civil project manager Matt Pohlhaus in a discussion on how artificial intelligence is transforming site design. Based in the Washington, D.C., metro area, Matt leads land use and civil engineering projects across Maryland and West Virginia. Increasingly, he says, AI is becoming as much a part of his toolkit as CAD software or site surveys.

“We use artificial intelligence daily,” Matt explains, describing how it’s woven into tasks both big and small—from communication to design. “If you’ve ever been stuck trying to get some language out the right way, just throwing a few prompts into ChatGPT or something similar” can result in a “very well-worded email” and freeing up time, he says.

On the conceptual side, his team is utilizing AI-driven generative design software. With just a site location and a few inputs, the program quickly produces fully fleshed-out site layouts. “When a client asks, ‘Can we put a 60,000-square-foot grocery store on this site?’ I can now show them in minutes,” Matt says. In the past, that answer might have taken days of drafting and another round of meetings.

The ability to test ideas in real time with clients has proven invaluable.

“The coolest thing about it is everything updates on the fly,” Matt says. He describes meetings where clients ask to move a building across the site or add a parking garage—what once required rescheduling is now an instant adjustment. “It becomes a lot more conversational,” he says. “I think clients tend to see us more as a partner than just a consultant drawing lines on a screen.”

A medical office building project, for example, completely shifted direction during a single meeting. The client had arrived with a looping driveway design they thought was final, but after moving the building within the AI model, the layout quickly evolved into something more straightforward, visible, and cost-efficient. “That was probably a 20-minute conversation,” Matt says. “And the scheme they ended up moving forward with was completely different from what they came in thinking they were going to do.”

Another project—an industrial site tied to a rail line—showed off the software’s deeper analytical power. The developer wanted to run railroad tracks into the property, but when Matt layered in topographical data, a problem appeared immediately: the proposed line ran over a 30-foot cliff. “If anyone’s been on a train before, they don’t go up and down hills all that well,” he says. By shifting the entry point half a mile, the team avoided an impossible design and a change that in the past might have taken weeks of back-and-forth.

Armand Harpin, Director of Federal Healthcare at IMEG, joins this episode to discuss the firm’s extensive work with the U.S. Department of Veterans Affairs (VA), Defense Health Agency (DHA), and Indian Health Services. Under Armand’s leadership, IMEG has been ranked the top Veterans Affairs engineering firm by BD+C Magazine.

“We serve the VA across probably 75 percent of the campuses throughout the country,” Armand says. These projects span a range of services, from facility condition assessments and master planning to infrastructure upgrades like boiler and chiller plants. “We've also spent a great deal of time over the last few years and are still involved in electronic health record projects for the VA,” Armand adds.

For most of the firm’s federal healthcare projects, IMEG collaborates closely with more than 20 service-disabled veteran-owned small businesses—partnerships that are extremely valued. “It’s a real pleasure to support those architectural and AE firms,” says Armand. On larger projects, those $100 million and above, the firm partners with national AEC firms across the country.

Armand says the federal healthcare market is currently experiencing a transitional period, with shake-ups in leadership within the VA’s Office of Construction and Facilities Management (OCFM). “They’ve lost their senior director, they’ve lost a good portion of their associate directors, and so they're in the process of rebuilding,” he says. This comes as the VA continues to face major issues with its building stock; most VA facilities are 50 to 60 years old, creating significant operational challenges. “It’s becoming more and more difficult... to provide for today’s healthcare needs,” Armand says. Some major campuses, he adds, are being “decanted,” with their services being moved to leased, community-based outpatient clinics in more population-dense areas. “That’s called ‘commercialization,’ and it's been a critical piece for bringing services and positive outcomes to veterans in underserved areas.”

Speed and efficiency in project delivery have become top priorities, with Armand citing increased use of design-build and integrated delivery approaches to accelerate project timelines. One such example is a $600 million healthcare center project in El Paso, Texas, currently being executed by IMEG in partnership with Clark Construction.

Armand has been involved in the federal healthcare market for many years and his work in the sector hits close to home. “My brother served in the Air Force. My father served as a Marine... and passed away in the VA hospital in San Diego,” he says. “This is an incredibly personal mission.”

His passion also dovetails with IMEG’s stated purpose to create positive outcomes for people, communities, and the planet.

“It’s a mission of stewardship, of accountability, and trying to provide the healthcare outcomes that VA and active military patients need,” he says.
