Winner of the 2020 Grands Prix du génie-conseil québécois
Transportation Infrastructure Category
At the 18th Grands Prix du Génie-Conseil Québécois, gbi was given the Best Transportation Infrastructure award for its Turcot Interchange dismantling project. The goal of this competition is to highlight the engineering expertise of the best projects in the industry. Each project is judged on the criteria of complexity, innovation and sustainable development.
A large-scale project
This project involved a total of fifteen complex overhead structures stretching over six kilometres of ramps, some reaching a height of 30 metres, and a 470 metre-long railway tunnel. The various ramps overlooked several obstacles, including the Lachine Canal, several CN rail lines and a former shunting yard, which generated its own share of complexity.
Innovations
To ensure safe demolition, several innovative methods and systems were developed to avoid any damage to the structures to be retained. In fact, the vast majority of the ramps to be dismantled were either above or close to new structures or active traffic lanes.
Several innovative stabilization, protection and vibration control systems were developed. This unique project required a high level of adaptability and precise coordination with the various on-site teams in order to develop methods adapted for each structure, which required extraordinary creativity.
