    In the Spring of 2010, University McGill and the Montreal Alouettes have enlarged the Molson Stadium. A new structure made of precast concrete allowed the addition of 5,000 seats and many private boxes.

  • George Washington Bridge

    Groupe Lefebvre and Venture Construction (American subsidiary), in conjunction with Bishop/Sanzari, have waterproofed the bottom level roadways of the bridge, as well as its access ramps on the New Jersey side.
