Meet the Winners

In joining ENR’s seventh annual Top Young Professionals conference earlier this year, the magazine’s 2023 selected group of rising construction professionals didn’t mince words weighing in on how industry should address key challenges, including implementing technology, climate change impacts and workforce development.

In candid conversations on stage and among peers, the Top 20 championed needed solutions. As skilled AEC professionals with successful careers in diverse industry sectors, their distinctive experiences provide them fresh perspectives on hotly debated topics. Even in the setting of the Big Easy for this meeting of the minds, the Top 20 recognized that collaborating outside of the office and jobsite to implement impactful innovation is no easy street.

Knowledge Sharing

AEC professionals often work in bubbles, says Tauhira Ali, executive director of industry innovation for the National Electrical Contractors Association. “We think that we’re the only ones who have problems with prefabrication, or managing your tech stack, or how to communicate even across teams in your company—much less across different trades,” she says.

Communication helps the industry grow, whether that’s reaching out to special interest groups, clients or to needed project team members, says Ali. She is doing the latter as organizer of an upcoming conference for skilled workers in electrical, sheet metal, mechanical and plumbing trades.

“Collaboration is at the core of what we do in our industry,” says Ryan Bauman, transit section manager at HDR Engineering. On a local level, he represents HDR through a collaboration with the University of Minnesota that enables aspiring engineers to learn about design plans side-by-side with HDR staff designers as part of a capstone project. For the Metro E Line project in Minneapolis, which runs through the heart of the University of Minnesota campus, Bauman says that one of the students’ first assignments was to find ways to improve riders’ experience.

Bauman says he’s seen the collaboration “really spark some of their careers, and I think that just helps the industry continue forward.”

Battling Burnout

At WSP, Megan A. McDonald, assistant vice president, transportation planning, leads an advisory group that has become a melting pot of not only company planners but also grant writers, policy strategists and transportation engineers, like herself, she says. Together, they all bring their respective specialties and experiences to the table on freight planning projects and phase one designs.

With the global design and professional services giant’s recent acquisitions, internal knowledge sharing at company lunch and learns has “become even more important” for WSP, says McDonald.

“It’s been this kumbaya moment for all the people coming together and trying to make a better environment for everyone to work together,” says McDonald, also a professional advancement committee member for the American Society of Civil Engineers. She notes that establishing formal knowledge-sharing pathways between managers and mid-level employees can break the cycle of those newly promoted learning their roles on the fly, and can help battle employee burnout.

Adapting to a Changing Climate

Margaret Hopkins, a Richmond-based specialist in climate adaptation and resilience planning design at AKRF Inc., could not attend the Top 20 roundtable, but still provided a host of solutions to challenges facing both public and private sector owners. She is hopeful that New York City’s program that mandates its capital projects to exceed building codes by incorporating climate projections into designs will extend to private owners. 

“The hope is that it establishes a best practice that demonstrates the value to private owners that these buildings built to a higher standard are experiencing fewer losses,” she says. 

Connecting her coastal clients in New York City, New Orleans and Virginia to share their own best practices with each other has paid off, Hopkins points out. “Instead of hearing it from consultants, they hear directly from someone who has done it,” she notes.

Although the Top 20 group acknowledges that being overworked in construction is not new, a new generational acceptance of burnout as a condition with symptoms that must be treated has pushed company leaders to find real solutions for the issue.

Younger millennials and Gen Z employees entering the workforce want to see how their work contributes to their quality of life, the Top 20 collectively agreed, emphasizing more attention to work-life balance.

From a legal liability standpoint, burnout has become a “huge topic” on construction jobsites, says Roscoe Green, an attorney who specializes in construction issues as a partner at law firm Adams and Reese. “A lot of our claims are burnout,” he says. “People working long hours, when combined with workforce issues, can creates a litigious environment. Our claims involve simple mistakes on projects from burnout, and just not having the skill level that’s needed.”

With an increasing demand for construction driving the industry to build better and faster, the Top 20 group agrees that there also is more opportunity for innovation—which can be as complex as a new software system, or as simple as a small change in how employers preserve and boost the mental and physical health of their employees.

“Reframe Systems is a five-month-old startup, and startups are notorious when it comes to burnout culture,” says Ankur Podder, head of design for the company. “But we realize that it’s an opportunity for us to set up a better culture.”

When an employee takes a vacation, his or her team gets a sanity check to be sure it can operate without that person. The company also heavily factors in vacation time when it comes to reaching productivity milestones. “We want to grow 10 times in the next year,” Podder says. “We cannot do it if everyone is not at their best mental health and productivity.”

Workforce Development

As a project superintendent for Hensel Phelps, Kabri Lehrman-Schmid has made the mental health of her jobsite crews an inseparable component of site safety with the simple strategy of just asking. In her view, “when we say burnout, we mean people who are either leaving the industry or unable to perform their work because of being overworked and no longer capable to do the job that they are expected to do.”

Since the start of the COVID-19 pandemic, Lehrman-Schmid says she has noticed a change for the better in cultural awareness related to talking about mental health. Doors have opened to address it, and as a result, people are more willing to discuss personal struggles that may be impacting their work.

“We are still figuring out the solutions of where we can and can’t promise the owner that we will have it done because we can’t work another 7-day week.”
Kabri Lehrman-Schmid

“The work that we perform on the jobsite is usually cited as the reason why there are mental health challenges in the construction industry,” she says. “Production-driven, they could be isolating from family. We have high-risk work.” At the jobsite level, burnout is addressed in how work is managed, Lehrman-Schmid adds. “The workforce is receptive to it, but we are still figuring out the solutions of where we can and can’t promise the owner that we are going to have [a project] done, because we can’t work another 7-day work week.”

AECOM program director Jaime Miller says the firm has made a shift to focus on wellness, but it’s been a challenge to execute. “People are aware of burnout,” she says. At the design, engineering and project management level, “I think a lot of it is coming from the technology,” says Miller. “We have more tools, every day there is a new system to learn, and all of these ways to stay connected, and that’s great. But it leads to more expectations on productivity.”

She emphasizes that “it creates this expectation that you are always on. That’s necessary sometimes but what I am finding is, there’s never an ebb and flow.”

Recruitment and Retention

At O’Connell Electric, investments made in employee resources such as training, mentorship and continuing education have helped company executives improve workforce development and recruit and train people they need from their own staff. “We’ve kind of given up on trying to find someone who’s already qualified,” says Dave Emmi, vice president of the firm's power group. “We found that we’re making qualified people internally, more and more, as time goes on.”

Additionally, he says the company has engaged its industry association to develop more robust training programs. “You’re taking someone who might have a learner’s permit, based on a four-year degree, and you’re going to shape them into the person you need them to be,” Emmi says. “We’re focusing a lot of our effort there.”

Cypress Environment & Infrastructure engineer and project manager Jennifer Sloan Ziegler says the company has taken a similar stance on workforce development to hire employees that they need now.

“We hire for personality fit, and train for what they need to know,” she says, despite some concerns about the future engineering pipeline and a high attrition rate. “There are a lot of people leaving the industry, especially civil engineering, and a lot of who are graduating with a civil degree and then not even coming into the industry,” Sloan Ziegler says. “So I am very concerned about what the next 5, 10, 20 years is going to look like for civil engineering. You don’t have enough people to do the work that needs to be done.” She is making a job change of her own, although staying in the industry, in a new role as senior environmental project manager at engineering firm Neel-Schaffer, effective May 30.

When a longtime employee leaves, “you lose the institutional knowledge that person had, unless the next generation of employees are developed enough to feel confident in their roles,” says Stephen Parker, a Stantec senior associate. “There is no amount of dollars and cents that can make up for it in terms of client relationships [and] engagement.”

Another problem facing the industry is labor cost inflation, he says, explaining that entry-level labor costs are at times equal to those for more skilled labor, once all costs are factored. Training and onboarding new employees can impact the total cost of replacing departing colleagues. Often it’s twice their salary, he says, making a substantial pay hike or benefit package worth considering to retain talented staff.

“Companies prefer hiring junior engineers, with a few years of experience, because they’re more willing to relocate and they’re asking for lower salary.”
Yanling Leng

“I’m finding that between fee squeezes on specific project types … inflation and workforce costs, that means [doing] more with less,” Parker says. “You want to make sure people feel valued and have a sense of purpose in their practice,” which can be difficult to achieve at firms when colleagues feel they don’t have voice and choice, he explains.

Steven Venditti, owner and president of Sparc Fire Protection Engineering, finds recruiting into small companies where employees have high visibility and input can also be a challenge. Sparc has six full-time employees. “Folks feel like they’re more stable at significantly larger companies,” he says.

Venditti says he came from a “fairly large” international fire protection firm that was employee owned, but eventually was taken over by a private equity firm. “That was one reason why I started this company, because things changed from the president knowing who I was, and going out to dinner, to [executives] not really knowing who I was. That just wasn’t enjoyable anymore,” he says.

As a senior-level professional, IMEG lead bridge engineer Yanling Leng says career development and the job market for experienced engineers is a “negative situation.” She adds that “a company might value their senior engineers, but they often do not know that.” Leng estimates that up to 90% of companies prefer to hire junior engineers, with a few years of experience, “because they’re more willing to relocate and asking for a lower salary.” Another challenge for senior engineers is that they often “do not know how to use [newer kinds of] software and technology,” she says.

To Sloan Ziegler, senior-level employees not knowing technology speaks to a key need to ensure that workforce development also includes keeping them current on technology and on new ways to work efficiently.

How Top 20 under 40 Winners Were Picked

ENR’s 2023 Top 20 Under 40 were selected from a total of nearly 600 nominations submitted last fall from across the U.S. and Puerto Rico. Candidates had to be under 40 years old as of Jan. 1, 2023. ENR’s 10 regional editions assembled local juries that each scored and selected up to 20 people. 

The top five scoring candidates in each region automatically advanced to the national level, where a new panel of independent industry judges reviewed the total of 50 nominees to choose 20 individuals who represent the pinnacle of leadership skill, community service, work ethic, talent and diversity.

An AI Idea

Sharing their respective experiences in adopting artificial intelligence into their workflows, the Top 20 group found that some industry sectors are further ahead than others in using AI tools.

In a recent mentorship check-in, a junior staff member asked Bauman about a business case for using AI in civil engineering design: how it could change the way the firm checks plans sets and eliminate hours of spell-checking plan sheets and related tasks.

“I’m a top young engineer, and I had no clue of anything he was talking about,” Bauman says, adding that the staffer worried about how to raise the technology gap to managers. “My response to him was ‘no, this isn’t a bad idea.’”

HDR traffic business class leader Sanjay Paul has seen AI work wonders in the transportation sector by removing human error with automated processes—such as detecting road hazards, adjusting light times at intersections and autonomous vehicle development.

Fear should not stagnate further AI adoption, he strongly believes. “We want to continue doing what we have been doing because it’s comfortable. It’s reliable,” Paul explains. “We believe that AI technology is the future.”

At Arup, planning and design leader Catarina Carvalho says AI is helping some clients address the high rates of shipped product returns, up to 30%, which are creating “more congestion and more emissions” in dense urban areas, even as they seek more pedestrian and green spaces.

She says the 2021 infrastructure investment law is incentivizing clients to reduce carbon emissions and embrace digitization, offering the construction industry a “once-in-a-lifetime opportunity” to make an impact. “I do believe our industry will be shaping a better world,” says Carvalho, adding that changes are already underway.

Beyond technology hardware and software, Ali says implementing AI can simply begin with gathering clean and usable data—because companies can’t improve something they’re not measuring. “Innovation doesn’t have to be the latest robot or the latest widget.Maybe it’s just creating a sustainable process,” she says.

Prefabrication is one such process that also reduces environmental impact by reducing waste, says Webcor Senior Vice President Allison McCue. “We need to be more efficient in the way that we build buildings,” she says. “There’s a lot of benefits that come with that prefab efficiency.”

Arup energy and digital leader Rob Best says prefabrication can also be used for “retrofitting for energy efficiency and decarbonization, particularly in the residential space where you have older buildings.” Related to efficient building envelopes, he says “there are good technologies being developed that allow us to …add insulation and quality air sealing” that can minimize costs with less field labor needed.

Conversations centered on decarbonization and climate change have ramped up significantly in the last few years, with direct impact on construction work, says the Top 20 group. “All our jobs are done outside, and if our employees can’t work outside, that’s bad,” says Kimberly Martin, Keller senior engineer for innovation and sustainability.

To correct the industry’s huge emissions footprint, AEC professionals must help owners step up to new levels of response, says Patrick Farnham, Langan senior project manager. “Development wouldn’t happen if it were not for the money,” he says. “But if [firms] say this is something we’re going to care about and be leaders in, that’s what is needed.”

Maria E. Chumbita, engineering vice president at CoreBrace, says owners don’t always realize that building just to code doesn’t account for the carbon footprint of entirely rebuilding after a natural disaster. “We need to think long term about what exactly is the premium to have a building that can be operational—or at least can be successfully repaired—after an event like [an earthquake].”

The industry needs collaborative change, McCue says. “It’s not going to be just contractors, just designers or just owners. We all have to move in the same direction together.”
