Hamilton, ON, Canada
When SucroCan decided to build Canada's largest sugar refinery in the Port of Hamilton, they knew there would be challenges.
However, with their raw material arriving via water, the location made absolute sense.
That didn't mean it would be easy. The site had some challenges.
Materials from the demolition of previous structures complicated the near-surface soil conditions. It doesn't get much better below. The native soil has low internal strength with N-values below 10 until 27 to 29 meters.
In consultation with MTE, the structural engineer, EBS determined that large round shaft helical piles were the best option based on site specifics, project timelines, and budget.
EBS designed round shaft helical piles with four-and-a-half inch, five-and-a-half inch and 7-inch diameters to bear loads of 445kN to 978kN in compression and 267kN to 623kN in tension.
The helical piles first passed through the layer of fil and debris. Moving on to shallow layers of sandy silts with trace gravel, sand and clay.
The site has a significant layer of Clay and Silt Til from 22 to 26 meters with N values of less than 10.
The helical piles are embedded in the very dense Sandy Silt Till to deliver the required capacity.
By customizing the helical Piles for the site with 30-foot lead sections and extensions, the EBS crew was able to install an average of 1500 ft per day (455 meters per day)
That's how EBS takes our Sweet Time.
