Aggie engineering

*aggy

Concrete has almost no strength or bond with the rebar until it hardens (i.e. initial set = 4 - 6 hours after placement).

Additionally "wet" concrete is relatively heavy (~150 pcf vs. 62.4 for water). 

Thus if the form system can't support the weight then a blow out or collapse will occur. 

Contractor probably tried to eyeball it and used experience to "design" the formwork and supports... or they hired an aggy to do it.
