Toronto, Ontario - Spadina Wavedeck

Riggs Engineering was engaged by Somerville Construction to provide an alternative design for the new Spadina wavedeck. The contract showed custom support beams made from hollow structural steel sections that varied in depth, but this was too costly.

 

Riggs Engineering redesigned all structural components below the timber components of the new Spadina wavedeck.

The design components included:

 

  • The replacement of the custom hollow section beams with steel “I” beams, which are more economical to supply and install. The primary steel beams had several joints to achieve the unique shape of the structure and were designed using finite element analysis.
  • The design of 500 mm diameter bearing piles resisted large uplift as well as ensuring fixity at the lakebed. The fixity was verified with above water horizontal load tests. 
  • The encapsulation of the existing crib walls was with H-piles and a concrete lagging wall.
