Patterson Grain 4 Bin Expansion – Assiniboia, SK
DSD (Sask.) submitted a design/construct “value engineering” submission to PTC Construction Ltd. (Winnipeg) for 432 caissons. The design was based on a combination load sharing of caissons and raft foundation to carry the specified service loads for the additional 4 bins.
All caissons were constructed to a depth of 7.6 meters below grade elevation and were belled out to a diameter of 1.02 meters.
The foundation piles were constructed ahead of projected schedule with no issues in relation to field construction.
