Giving props to industry employees who are making strong impressions in the opening chapters of their careers is the hallmark of ENR MidAtlantic’s Top Young Professionals competition. 

After considering more than 40 entries from across the region, a panel of industry judges selected 20 winners in the contest previously known as Top 20 Under 40. Working in Delaware, Maryland, Pennsylvania, Virginia, West Virginia and the District of Columbia, the winners were all younger than 40 as of Jan. 1. The nominees themselves or one of their advocates submitted online forms about their experience, education, career and industry leadership. The submissions also outline each candidate’s community service.

This year’s judges were: Cheryl Browne, creative and brand manager at W.M. Jordan Co.; Julie Evans, transportation systems engineer at ITS Roads; Shane Lippert, project executive at Clark Civil, a division of Clark Construction Group LLC; Brian Martin, senior associate at CallisonRTKL Inc.; and Geoffrey Pelletier, associate vice president, MidAtlantic construction services at HNTB Corp.

This year’s winners worked on high-profile projects such as the $15.5-million U.S. Capitol Exterior Stone and Metal Preservation in Washington, D.C.; the $80-million Liberty Bridge renovation in Pittsburgh; and the ongoing $1.2-billion Dulles Corridor Metrorail Project, which runs from Arlington, Va. to Loudoun County, Va.

Giving back to their communities through pro bono building and design programs as well as volunteering for nonprofits that help people from all walks of life are priorities for this year’s honorees. They also volunteer to serve on industry boards and committees.

The winners of ENR’s regional competitions will be candidates for ENR’s national contest, which will determine the 2019 Top 20 Under 40 class later this year.

Nicholas BurdetteNicholas Burdette
Childhood dream comes true for bridge specialist

Senior Bridge Engineer

The 37-year-old has been fascinated by bridges for as long as he can remember, and they have become the focus of his career. Burdette has had important technical and management roles on a variety of challenging projects in the U.S. and overseas.

As assistant project manager for the $80-million Liberty Bridge renovation in Pittsburgh, Burdette helped lead HDR’s emergency response to an inadvertent construction fire that severely damaged 30 ft of chord truss subject to substantial loads. Thanks to the project team’s concerted efforts, the project’s completion was delayed by only four weeks. HDR says Burdette’s ability to take on critical new responsibilities at a moment’s notice complements his willingness to explore new approaches to bridge construction.

Burdette’s recent work also includes the new Gov. Mario M. Cuomo Bridge—the replacement for the Tappan Zee Bridge—in New York state and the Herbert C. Bonner Bridge replacement on North Carolina’s Outer Banks. On both projects, accelerated bridge construction techniques were used to help speed delivery of safe, reliable structures.

Design Corps Manager
Burns & McDonnell
Roanoke, Va.

As mechanical engineer and design corps manager for Burns & McDonnell, the 37-year-old leads a 60-person multidisciplinary team that focuses on critical projects.

One of his most recent efforts can be found at Naval Station Norfolk, where communications operations that had been dispersed among eight outmoded buildings have been consolidated into a modern 163,525-sq-ft facility. Castelvecchi ensured that building systems were designed for efficiency, reliability and resilience under all conditions, Burns & McDonnell says.

Recognizing the mission-critical requirements of government and military projects, Castelvecchi works to make sure in-house knowledge and skills related to those projects are retained and shared as new work gets underway. He has established specific communications channels to capture lessons learned and make them available for future application.

Castelvecchi also continually looks for ways to inspire the next generation of science, technology, engineering and math professionals. For example, he organized and hosted a Big Brothers Big Sisters’ event at Burns & McDonnell that provided children with STEM-related activities, tours and presentations that aim to capture their interest.
