Owen Sound, Ont. - Harbour Rehabilitation


Riggs Engineering was retained to provide a routine detailed inspection of the Owen Sound harbour structures and identified that ╩║Structure 2╩║ had deteriorated due to damaged piles and lack of structural bearing of the superstructure. The bearing issues relate to a combination of deteriorated concrete and timber pile tops.


Riggs Engineering provided repair alternatives as follows:


  • Encapsulating the existing timber piles with fiber reinforced plastic wrap;
  • Replacing the damaged bracing system;
  • Reinforcing split timber piles with steel banding; and
  • Installing permanent steel forms as part of the concrete restoration.


The restoration improved the overall stability of the structure and restored the timber piles’ capacity.
