Switching Station

Toronto, Ontario

A large switching station located in Toronto required a deep foundation solution for the support of proposed towers, equipment skids, cable trays and lighting masts. EBS designed and installed Chance Helical Piers to minimize the required excavation, create no vibrations or spoils, and used compact equipment to allow for work in close proximity to existing structures.

Compression Load: 890kN (200 kips) 
Tension Load: 845kN (190 kips) 
Depth: 10 to 18 metres 
Total Number of Helical Piles: 108
