TOPSHAM — Last year was a time of growth and expansion for Wright-Pierce, a multi-disciplinary engineering consulting firm serving clients throughout the Northeast, improving the firm’s ranking by 32 positions in the Engineering News Record (ENR) 2013 “Top 500” listing of design firms.

ENR, a trade publication and AEC (architecture, engineering and construction) industry observer, compiles and publishes annual rankings of the largest engineering and construction firms in the U.S., measured by gross revenues.

Wright-Pierce has been ranked in the Top 500 for five consecutive years, and with 16 percent revenue growth in 2013, the firm attained its highest ranking to date.

Wright-Pierce has expanded its staff by 20 percent since early 2013 to nearly 200 people, adding depth and breadth to both technical and management teams. A Manchester, N.H., office was opened in June, and major expansions have recently been completed at the Andover, Mass., and Middletown, Conn., offices.

Bill Brown, president and CEO, attributes the 65-year-old firm’s growth and higher ENR ranking to “our strong commitment to working with our clients to identify and implement the best, most sustainable solutions for their infrastructure needs.”
