Sustainable cities

- Deconstruction of Buildings - The End of Demolition

The word demolition is out of fashion. Today, we are talking about deconstruction. The concern for the environment, the reduction in the volume of materials intended for landfill, but mainly the economic potential associated with the upgrading of certain materials leads demolition contractors to move towards deconstruction. More and more tendering documents are asking for a plan for the management of residual materials and the revalorization of materials. In this presentation, we will see through various GHD projects how deconstruction has proven to be the best option for managing sustainable development, where the environment is combined with the economy.

- Keeping gypsum waste out of our landfill: a pilot project in the Laurentians

The conference will examine the gypsum waste recovery pilot project carried out in the Laurentian region in 2018. Drawing from the expertise and cooperation of the Régie intermunicipale des déchets de la Rouge, Synergie Économique Laurentides established the source of deposits across the territory of three regional county municipalities and worked closely with entrepreneurs to recover gypsum waste from worksites. In parallel, a study was performed to evaluate the potential of regional opportunities as well as determine best practices to develop an efficient waste recovery system. The conference will cover all project stages and results.

- The Champlain Bridge deconstruction: enhancing assets and recovering materials

The Jacques Cartier and Champlain Bridges Incorporated (JCCBI) is a federal Crown corporation that reports to Canada's Minister of Infrastructure and Communities.The current Champlain Bridge, which is managed by JCCBI, is coming to the end of its service life, which means that its deconstruction poses many challenges in terms of methods engineering and managing residual materials from the bridge. While looking to principles of the circular economy to recover, reuse and enhance as much of the structure's assets and materials as possible, JCCBI is launching sustainable development programs to soundly and effectively manage all aspects of the project. Given that Montreal is the site of a great deal of construction work, it is important to optimize projects so that we can maximize returns on our social and environmental investments while soundly managing public funds.
