The Ontario Building Code | Incorrect Placement of Shallow Foundations
4.2.6.3. Incorrect Placement of Shallow foundations
(1) Where a shallow foundation unit has not been placed or located as indicated on the drawings,
(a) the error shall be corrected, or
(b) the design of the foundation unit shall be recalculated for the altered conditions by the designer.
In Plain Language
Where a shallow foundation unit hasn't been placed or located as the design intended, the situation must be evaluated and addressed rather than simply left as built, since incorrect placement can undermine the design's assumptions.
