Responsible Project Delivery
Aecon helps our clients meet high sustainability standards by executing every project responsibly, not just following the rules but actively seeking ways to reduce waste, mitigate harm to local ecosystems and respond to community priorities and concerns. Making a meaningful commitment to the principles of sustainability not only aligns with our values, it reduces costs, builds public support for projects, and helps our clients achieve their own goals in areas such as waste and emissions reduction. Examples include:
Highway 401 Aggregate Recycling: Aecon is part of a joint venture engaged to design, build, and finance a major reconstruction and expansion of Highway 401. We’re using 300,000 tons of recycled aggregate (70% concrete, 30% asphalt) to realize the widening of this 18-kilometre stretch of highway. Recycling aggregate has numerous business and environmental benefits, reducing the costs, energy usage, and land use associated with the excavation and transportation of new material from new gravel pits and other processes. Achieving these efficiencies is standard practice for Aecon — we recycle 150,000 tons of aggregate annually at our Brampton Depot. For the 401 project, we’re collaborating in the development of an on-site program that we expect will support the recycling of about 1 million tons of material through 2022.
Gardiner Expressway Steel Recycling: Working to rehabilitate Toronto’s Gardiner Expressway, Aecon teams have taken advantage of numerous opportunities for the reuse and recycling of building materials. As we’ve prepared to replace portions of the expressway deck, we’ve cut away 407 panels of the existing deck and hauled them to a nearby recycling yard to be broken down. In all, we expect to enable the recycling of approximately 5,000 tonnes of steel into new components or mixes for other projects. We also anticipate that most of the 23,000 tonnes of concrete from the expressway will be cleaned, crushed, and reused.
Kitimat Meter Station Construction: Mitigating Ecological Impacts — as the prime contractor on the Kitimat Meter Station, a facility that will help natural gas move safely through the Coastal GasLink pipeline, Aecon committed to working actively with all project partners to meet local commitments — environmental and social. We supported significant efforts to mitigate the environmental effects of construction. As one example, we relocated approximately 40,000 tadpoles to a location where they could mature safely. Our team also supported grassroots environmental initiatives locally, including volunteering to participate in a river clean-up.
