Hatch has been awarded Bentley’s Year in Infrastructure 2020 Award

 

Ontario, Canada - Hatch is excited to have been awarded Bentley Systems’ Year in Infrastructure Award 2020 for the Ashbridges Bay Treatment Plant Outfall project. Due to the COVID-19 pandemic, this year’s awards gala took place as a virtual broadcast on October 21, 2020.

Bentley's Year in Infrastructure 2020 Awards is a global competition that recognizes advancements in infrastructure.

For this project, our team was responsible for the design and construction of a new tunneled outfall that is projected to be the largest wastewater outfall in Canada. The outfall extends approximately 3,500 m offshore and will send treated effluent along a 7 m diameter tunnel from the Ashbridges Bay Treatment Plant into Lake Ontario. Our client, The City of Toronto, specified that the new outfall be designed to allow treated effluent to flow by gravity from the plant, through the outfall, and into the lake using less than 1 m of hydraulic head to convey peak design flows.

As noted in Hatch’s Bentley Award submission, Bentley software was applied to address two significant challenges on the project: (1) prediction of underground geotechnical conditions using limited availability of offshore boreholes; and (2) selection of the tunnel alignment. All major elements such as on-shore effluent conduits, shaft support of excavation and final lining, tunnel liner, riser-to-tunnel connections, risers, ports, and port protection were also modeled in three dimensions using Bentley’s software. These same 3D models assisted tremendously in collaborative technical peer review and constructability review workshops to enhance the design and perform value engineering. Hatch’s global team was also able to access the project and execute their work within ProjectWise, allowing real-time design collaboration and CAD model updates.

Hatch, with Bentley’s support, effectively and efficiently delivered the Ashbridges Bay Treatment Plant Outfall project for the City of Toronto.

“Celebrating our talented team’s dedication to digital delivery, collective intelligence, and collaboration was the winning formula for success,” noted Russell Pye, Senior Specialist, Visualization and Graphics.

Congratulations to the entire project team for their win!
