TBM: TUNNEL BUSINESS MAGAZINE // OCTOBER 2018 Keller, a leader in geotechnical solutions, announced the completion of its first cutter soil mixing ( oject in Canada. Keller performed the project for Aragon Proper- ties Ltd. in P ody, British Columbia, at a new mid-rise development complex called Platform. d for areas in the lower mainland and Pacific regions of Vancouver with deltaic alluvial flow deposits where there are few obstructions. Developed from diaphragm wall technology es two sets of counter rotating, vertically mounted cutter wheels that cut the surrounding soil and blend the injected cement slurry with the in-situ soil to form soil cement panels. Keller performed earth retention and ex- cavation support at 2718 Clarke Street on the approximately 38-m tall by 79-m wide property to aid in the establishment of Ara- gon's modern living spaces. A shoring wall was designed as a temporary earth re- tention structure. Field Engineer Johannes Reinisch explains that construction included the supply and installation of almost ninety nearly 16 m. Keller then completed the installation of er- intendent Br y was pleased to report that production finished one week ahead of schedule due to Keller exceeding production targets. "Working with Keller was a big win for us and we highly recommend them," said Kris Hel- lens, EIT, Senior Project Coordinator for Aragon Construction Corp.

So t a diameter of more than 20 ft and stretching more than 400 ft in length will begin her journey on one of the most signif- icant public infrastructure projects in the history of the Community. She will grind through bedrock to build a five-mile-long sewer tunnel, more than 200 ft under the earth's surface, with an interior diameter of 16 ft. "In six years when the tunnel is operational, we will see several ben- efits. The biggest benefit will be a 90 percent reduction in the amount of combined sewer overflow going into our rivers. That's a reduction of more than 850 billion gallons on average each year, tthew Wirtz, Depu- ty Director of Engineering for City Utilities.

The deep-rock tunnel is a significant portion of the effort to clean-up Fort Wayne's rivers and protects neighborhoods from basement back-ups and street flooding.
