Sunnybrook Hospital Retrofit

Toronto, Ontario

A foundation retrofit of an interior operational wing at Sunnybrook Hospital posed challenges including no exhaust from equipment, limited noise, no vibrations or spoils and limited access through hallways. EBS designed the least intrusive deep foundation system to support the proposed retrofit, which offered 50% savings in cost and schedule.
