Conestoga-Rovers & Associates, which has offices in Baton Rouge, Lake Charles and Shreveport, is merging with GHD.

Employee shareholders in CRA will become shareholders of GHD. The transaction is subject to shareholder and regulatory approval and is expected to close in July.

CRA is a 3,000?person engineering, environmental, construction and information technology services firm. Founded in 1976, it has more than 100 offices in the U.S., Canada and the United Kingdom and has worked with clients in more than 60 countries.

Established in 1928, GHD is a global engineering, architecture and environmental consulting company with more than 5,500 people across five continents. GHD serves clients in the water, energy and resources, environment, property and buildings, and transportation industries.

“CRA was seeking a way to leverage our 38 years of private sector engineering and environmental services into a more diverse business with a global presence while staying staff-owned,” said Ed Roberts, CRA’s president. “We found a merger partner that has an overall philosophy, business approach and work ethic similar to CRA’s.”

“CRA’s strengths in the private sector in North America are an excellent fit with our strategic plan,” GHD CEO Ian Shepherd said, “and GHD’s global footprint and technical skills fill much of CRA’s strategic objectives.”
