The companies are two of the largest engineering firms that operate hydraulic modeling laboratories in North America. Under the merger plans, LaSalle will remain a separate company, Lasalle|NHC, a wholly owned subsidiary of NHC.

Both companies specialize in design, construction, and testing of constructed physical models of engineering designs and river systems. NHC said the merger would substantially increase its laboratory and staff capacity in constructing and testing physical hydraulic models; provide wider services in the water resource sector to existing and new clients across North America and internationally, and draw on the combined expertise developed at NHC and LaSalle.

"We are very excited to have LaSalle join us to enhance our capabilities to serve clients and expand our geographic presence" said NHC President Herb Wiebe.

"It’s a fit that makes sense.," added Brian Hughes, NHC’s director of physical modeling operations. "Both firms are highly regarded in the industry, but operate mostly in different geographic markets. The merger will allow us to share work and specialized expertise to provide more comprehensive services to existing and new clients."

Marc Villeneuve will assume the role of President of Lasalle|NHC and has been appointed to the NHC Board of Directors. All LaSalle owners will remain at Lasalle|NHC and are acquiring NHC shares as part of the acquisition.
