BOSTON MA (May 22, 2007) TSX:STN; NYSE:SXC

Stantec announced today that it has acquired the assets of Boston firm Geller DeVellis Inc. and that the Geller employees have joined the Company. The transaction adds approximately 50 employees to Stantec’s growing New England operations and increases the Boston office to over 65 people.

“The skilled professionals and services the Geller DeVellis team offers are a tremendous addition to our company,” says Stantec President & CEO Tony Franceschini. “New England is an important market for Stantec’s success on the East Coast, and this addition gives us a much stronger presence in Boston.”

Geller DeVellis specializes in planning, landscape architecture, and civil engineering design projects, including the 9/11 memorial labyrinth at Boston College and the Teddy Ebersol Red Sox Fields on Boston’s Esplanade. With offices in both Boston and Wellesley, Massachusetts, the company also includes the Geller Sport division, which focuses specifically on recreation and athletic facility design projects, and the Geller Graphics division, which provides expertise in digital imaging, 3D modeling, and computer rendering.

“Joining Stantec allows our staff and our clients to continue the great work we do with the added benefit of Stantec’s considerable resources,” says Geller DeVellis president Joseph Geller, who will continue with Stantec as a senior principal.

Since 2003, Stantec has added 50 offices on the East Coast, growing from 300 employees to over 1,350 from Maine to Florida. Stantec now has about 70 offices in 26 states and more than 3,000 employees throughout the United States.
