More than a Century of Engineering Excellence

In 1885, William Barclay Parsons founded Parsons Brinckerhoff in New York City. Early projects included the design of the original New York City subway system and the Cape Cod Canal, as well as consulting for hydropower projects in New York State. The firm has worked on many of the major transit systems in the U.S., including San Francisco, Atlanta, Los Angeles, Salt Lake City and Seattle, and has designed countless highways, bridges, and tunnels, in addition to consulting on energy, water/wastewater, and community development projects.

Chas H. Sells, Inc. was founded in New York in 1925 and was acquired by WSP in 2007, becoming the transport and infrastructure engineering group of WSP in the U.S., with a specialization in bridge design and engineering. During its history, Chas H. Sells has worked on such iconic New York projects as Verrazano-Narrows Bridge, the Brooklyn Bridge, the George Washington Bridge, the Bronx-Whitestone Bridge and the Gowanus Expressway. The firm is also known for its expertise in the planning and design of large-scale developments including residences and offices.

Other acquisitions integral to the firm’s history include Cantor Seinuk, a structural engineering firm established in 1953, which joined the company in 2000, and Flack + Kurtz, a mechanical, electrical and plumbing engineering business founded in 1969, which was acquired in 2000. The two firms later comprised the buildings service line of the company. Environment & Energy, an environmental and energy consulting business established in 1986, became part of the company in 2006. The Colombian firm, Consultores Regionales Asociados CRA S.A.S. joined the company in 2012.

WSP acquired ccrd, a mechanical/electrical/plumbing engineering firm based in Houston, Texas, in 2014. The following year, Halvorson and Partners, a Chicago-based structural engineering firm, joined WSP. In 2016, WSP acquired the water management division of Schlumberger, allowing the firm to establish a presence in Chile and Peru and expand its water consulting services worldwide. Also in 2016, WSP acquired substantially all the assets of CRC, a New York-based firm with expertise in central utility plants and cogeneration systems. In 2017, the firm acquired three firms: YR&G, a national firm specializing in sustainable consulting, education and analysis; Willoughby Engineering, a mechanical/electrical/plumbing and building performance firm; and Leggette, Brashears and Graham, a groundwater and environmental engineering services firm.

All of the aforementioned firms are now part of WSP USA.
