Pre-loaded micropiles at Credit Valley Hospital – …..Revisited
Project Report for IWM 2004 Tokyo Jim Bruce Geo-Foundations Contractors Inc, CANADA

BUT….. After all piles installed, excavation revealed different conditions than anticipated!
Columns eccentric to drilled shafts Some square piers between column and shaft, some with no piers Most shaft tops just below grade
5
This was a problem because…..
No new cap allowed above grade All new micropiles were already drilled concentric to column Pre-loading still required
6
The answer….. A working design applicable to every one of 13 shafts
A completely new mode of pre-loading Saw cutting of piers to allow placement of column reinforcement Saw cutting of shafts to allow placement of beam reinforcement
