Kristin Bleedorn
Not your average acoustics consultant
34, Acoustical Associate
Shen Milsom & Wilke
New York City

As a woman whose professional engineering license is in acoustic consulting, Bleedorn is a self-professed minority. But at Shen Milsom & Wilke in New York City, she showed she was an innovative engineer, tackling projects that range from college classrooms and health care facilities to television production suites. Her work included projects at SUNY Stony Brook, Deloitte headquarters and Perkins Eastman. "Kristin's design solutions were both creative and successful throughout the project," says David Larson, associate principal at Perkins Eastman, where Bleedorn was acoustic consultant on two medical interior renovations. Other notable projects involved work for Mt. Sinai Medical Center, Cornell University and Memorial Sloan Kettering Cancer Center. Bleedorn also mentors students in the ACE Mentor program and was co-director of a national conference of the National Association of Engineering Student Councils at Iowa State University while gaining a B.S. degree in acoustics and engineering science. Since her Top 20 Under 40 citation, Bleedorn now has become a senior associate at Longman Lindsey, New York City.



Jason Cabral
Managing large-scale transmission projects
34, Project Manager, Transmission & Distribution
Burns & McDonnell
Wallingford, Conn.

Cabral has been managing Burns & McDonnell's billion-dollar projects for eight years, taking on the largest and most complex electrical transmission jobs in his field. He started in his position as program manager for utility firm FirstEnergy's $1-billion Large Transmission Project Program, quickly growing a team of four to 70 members. With this team, Cabral assembled a vast program management model for FirstEnergy. His work on the project earned Burns & McDonnell another contract with that client, a $2.8-billion initiative called Energizing the Future. Cabral also managed all overhead transmission line construction on Northeast Utilities' Greater Springfield Reliability Project. Over this past holiday season, Cabral set up a toy drive to help support the Akron Children's Hospital in Ohio, corralling project team members and clients to donate. He hopes to make this an annual initiative.


Jesse Chrismer
Specializing in sports structures
34, Associate
Thornton Tomasetti
New York City

As a recent associate at Thornton Tomasetti, Chrismer has become known in the company for his expertise in sports structures. He is now leading a five-office- wide structural design effort to build Rogers Place, the future home of the National Hockey League Edmonton Oilers—while simultaneously managing schematic design on a 23-story residential tower, a 2-million-sq-ft mall and a future Major League Soccer stadium. Large projects and dynamic time lines are Chrismer's forte. He has led the fast-tracked design of Panasonic's new headquarters in Newark, was full-time structural site representative at Yankee Stadium and led footprint design for Brooklyn's Barclay's Center. On the stadium, Chrismer began mentoring New York ACE Mentor program students, with three going on to win scholarships. In 2013, the group recognized him as its mentor of the year.



Rick Cianfaglione
Construction scheduling expertise helps a design firm expand services
35, Vice President
Middletown, Conn.

With an extensive background in construction scheduling and analysis, Cianfaglione has quickly climbed the ladder at ARCADIS US to become associate vice president as well as an officer and shareholder. As one of the youngest officers of the 22,000-employee global firm, he leads 10 schedulers and guided schedule reviews last year for public and private clients across the U.S. With "over 95% of claims submitted on construction projects having a delay component in them, Rick's scheduling experience was very valuable," says Roy Cooper, ARCADIS vice president. "Some clients began to request that our firm review submitted schedules while construction was progressing. Since then, this practice has grown exponentially." Among key projects are the Connecticut Convention Center in Hartford and work at Northeastern University. Cianfaglione has gained advanced certification from the Association for the Advancement of Cost Engineering International and the Construction Management Association of America and is working on an MBA. He donates some of his industry speaking fees to aid autism advocacy groups that helped his own son's diagnosis and treatment.



Seth Condell
PM is a multifaceted bridge builder
39, Senior Project Manager
Parsons Transportation Group
New York City

Engineering experience on such complex bridge projects as Lions Gate in Vancouver, Tacoma Narrows in Washington state and the new A-25 cable-stayed span in Montreal has enabled Condell to stand out as senior project manager at Parsons Transportation Group. On his current project, the new Goethals Bridge, Condell wears the hats of deputy design manager, civil design manager and chief of engineering support during construction for the $1.5-billion Port Authority of New York and New Jersey project. The bridge will replace the existing 87-year-old span between New York and New Jersey. As a younger engineer, Condell helped launch a publication titled "A Civil Engineer's Guide to New York" that featured the region's iconic and major engineering projects; now he's sharing his own megaproject experience through numerous papers and involvement in the ACE Mentor Program. Remembering his own early connection to the industry through Boy Scout merit badges in engineering and the physical sciences, he also is active in that group in Commack, N.Y.

Peter J. Martin
Doing what's right for construction clients in a very litigious industry
37, Partner
Hinckley Allen

While Martin understands the strategies that enable collaboration among construction owners, contractors and design professionals, the attorney also knows how to be effective when disputes occur, says Robert V. Lizza, partner in Boston-based Hinckley Allen and vice chair of its contracts group. Martin, who manages the firm's Connecticut construction practice, has become an experienced advocate for clients and a resource for industry groups seeking political and regulatory change. Lizza notes Martin's successful outcome in a complex arbitration involving a "high-end" residential homeowner's $100-million claim against his client, an architect, for defective design, delays and fraudulent misrepresentation. After nine days of arbitration, the homeowner's claims were denied, and Martin recovered damages for his client. Through extensive writing and construction group participation, the attorney shares his expertise and insights on complex legal opinions and issues that have broad industry ramifications. He strives to create a work-life balance that includes his seven-year-old twins and their little league peers
