From creating tech-driven efficiencies in public infrastructure to advocating for a diverse and inclusive workforce, ENR Northwest’s 2020 Top Young Professionals are mapping out the industry’s future as managers, leaders, mentors, researchers and experts. And that’s just in their day jobs.

These 10 individuals, under 40 years of age and from the Northwest region (Alaska, Oregon and Washington), use their substantial experience on some of the region’s most complex projects to encourage a new generation to join their ranks in construction and STEM careers. 

From coaching youth flag football and recruiting students at their alma maters to serving on nonprofit boards and building tiny houses, the deep commitment to service displayed by this year’s honorees reflects one common theme: These young leaders work beyond nine-to-five to share their passion for the good of their communities.

The Top Young Professionals competition honors up-and-coming leaders in architecture, construction and engineering. Nominees are judged by a volunteer panel of their peers. The 2020 judges were Ronny McPherson, an ENR Northwest 2019 Top Young Professional and coastal and maritime program lead at HDR Inc. in Anchorage, Ala., and Carly Avery, senior design and marketing project lead at Howard S. Wright, a Balfour Beatty Co., in Seattle.

The judges considered nominees based on their industry experience and education, leadership and community service and involvement. Next, the winning honorees will advance to compete for ENR’s National Top Young 20 Under 40. The national winners will be announced this spring. 

Congratulations to this year’s ENR Northwest Top Young Professionals! Winners from California and Hawaii will be highlighted in the March 30/April 6 issue.

35, Construction Manager
Guy F. Atkinson Construction
Renton, Wash.

With 12 years of experience managing the construction of bridges and highways, Barnes has completed more than $785 million in alternate delivery infrastructure projects, including six Washington State Dept. of Transportation design-build projects. He has managed construction on highly congested freeway corridors in the Seattle metropolitan area and in downtown Los Angeles.

In 2006, Barnes began working for Atkinson after graduating from Central Washington University. He acted as construction manager on the firm’s I-405 - SR 167 Interchange Direct Connector Project, which included a flyover bridge joining high-occupancy toll lanes with high-occupancy vehicle lanes by reconstructing portions of the current infrastructure to accommodate new direct connector ramps.

Barnes is currently managing the I-5—Steilacoom DuPont Road to Thorne Lane—Corridor Improvements for WSDOT using design-builder initiated change. It’s also Washington’s first project to use TrueTech Bridge stay-in-place ClearCast deck forms.

An active leader, Barnes encourages co-worker participation in company-sponsored social and community service events. For the last five years, Barnes has mentored new students in the University of Washington construction management program. He also leads a group of high school students through his local church and coaches youth flag football.

Portland, Ore.

After earning his bachelor’s degree in construction management at Washington State University, Holden began his career as a project engineer at Skanska’s Seattle office working for one of the firm’s longtime clients, the Boeing Co.

In 2015, Skanska selected Holden for its highly competitive international development program, “Skanska Stretch,” for high-potential employees early in their careers. The program’s culmination was Holden’s yearlong assignment in Oslo to work on Skanska’s Commercial Development-Nordics team, where he participated in feasibility studies, development calculations, lease negotiations and project oversight.

A native Alaskan and Yupik Eskimo, Holden shows a dedication to inclusivity and diversity in construction, according to co-workers. Holden serves as the executive chair of Skanska’s Young Professionals and leads training in the firm’s BOOST program, a 10-week training program for SBE/DBE/ MWESB firms.

Holden volunteers with the ACE Mentor Program of America, a free, award-winning after-school program designed to attract high school students into pursuing careers in the architecture, construction and engineering industry as well as skilled trades.

Additionally, as an alumnus, Holden leads annual recruiting efforts at Washington State University.

Brandon MaurisakBrandon Maurisak
32, Transit Engineer
Portland, Ore.   

With his expertise in rail transit, Maurisak’s colleagues commend his often self-taught tech-savvy approach to efficiency. Working from AECOM’s Portland, Ore., office since 2016, Maurisak is a line section manager on the design team of the Tri-County Metropolitan Transportation District of Oregon’s (TriMet) light rail extension project.

Maurisak previously served as an inspector and office engineer on TriMet’s Blue Line Station Rehabilitation Project, for which he resolved design conflicts, minimized delays and change orders, and recommended a simplification process of temporary station platforms that coordinated with multiple agency departments. He generated visual inspection reports for safety certification using BulkPDF and documented the process to share with TriMet so they could benefit from the new efficiency.

He was first hired by AECOM in 2010 as a track design engineer in Duluth, Minn., where Maurisak worked on Minnesota’s MetroTransit’s Southwest Corridor Light Rail extension, a 14.5-mile, $2-billion endeavor.

Maurisak holds a bachelor’s degree in civil engineering from Michigan Technological University and is a 2015 graduate of the American Public Transportation Association’s emerging leader program. He currently serves on the board of directors of the Evergreen Curling Club, where he is webmaster and volunteer coach, instructing new curlers from elementary school through retirement age.

Eric SolemEric Solem
38, Senior Project Manager
Exxel Pacific Inc.

Solem started his construction career in high school as a framing crew laborer and carpenter. To pay his way through Point Loma Nazarene University, where he earned a bachelor’s degree in social science, he built custom cabinets and furniture—and eventually founded a company doing the same. When he joined Exxel Pacific in 2015 as a project manager, his experience as a small subcontractor was transformed into a passion for helping small businesses.

As Solem rose in title and took on larger and more complex projects, the same high-profile client requested him five years in a row to work on four separate projects. After just three years at Exxel, Solem was nominated for 2018’s Employee of the Year. He serves as a member of Exxel Pacific’s safety committee, operations committee and STIP Committee, and is the firm’s diversity and inclusion coordinator.

He currently serves on the AGC of Washington’s diversity and inclusion steering committee and helped draft the Culture of Care initiative, which promotes workplace diversity and was adopted by nearly all Seattle AGC members. AGC now uses the initiative as a national model.

Solem is a board member of Apprenticeship & Non-Traditional Employment for Women (ANEW) and Pre-Apprenticeship Construction Education (PACE), both of which express his passion for continued apprenticeship training that leads to lifelong career with a living wage.

Solem worked with the Tiny House build project for Seattle’s homeless population and helped coordinate 300 volunteers to build 30 tiny houses in two days.
