New Bridge across St. Lawrence river

September 15, 2017

TCG is working for TY Lin and International Bridge Technologies along with SNC Lavalin, and Flatiron.  This fast track bridge construction will replace the existing Champlain Bridge with a $3.2 Billion-dollar structure.  TCG is the Joint Venture’s durability consultant to assure 125 years of low maintenance service life. TCG completed durability design based on a probabilistic analysis and in accordance with fib Bulletin 34 for the reinforced concrete elements. Concrete cover requirement for the piers in the water was determined by taking into account the effect of ice abrasion on concrete. Protection for structural steel in the form of coatings and sacrificial steel was designed. The potential of stray current interference from a future light rail transit system on reinforced concrete was evaluated. TCG is responsible for protection plans and specifications for all non-replaceable concrete and steel bridge elements.
