EDMONTON AB, NORTH SPRINGFIELD VT (February 15, 2006) TSX:STN;NYSE:SXC

Stantec announced today it has signed a letter of intent to acquire the multidiscipline design firm Dufresne-Henry, headquartered in North Springfield, Vermont. Dufresne-Henry has over 275 employees and 16 offices located in the northeastern United States and Florida. The firms expect to complete the transaction in late April subject to customary conditions and upon completion of satisfactory due diligence.

“We’re looking forward to the prospect of having Dufresne-Henry join with Stantec,” says Tony Franceschini, Stantec President & CEO. “The addition of Dufresne-Henry will give us a strong foothold in the New England states, complement our New York operations, and establish an initial platform for growth in Florida.”
