ABSTRACT: A 23-storey tall residential condominium tower is currently under construction in Waterloo, Ontario. The condominium consists of a 23-storey tower and two attached 3-storey podiums. The combination of the tall tower and shorter podiums resulted in extreme differential loading between the tower raft foundation spread footings under the podium. This presented risk of excessive settlement across the raft footprint and between the tower raft and podium footings. In order to limit the total and differential settlements, Geopier Rammed Aggregate Pier® ground improvement was used under the raft foundation. The spacing of the pier elements varied to provide a variable stiffness profile, greatly reducing the potential for differential settlement. This paper will present the design and construction methodologies along with results of verification testing of the ground improvement system used for this project and will review initial settlement monitoring data to corroborate the design.
