9.15.4.2.(2)

Intent 1:

To limit the probability of insufficiently thick concrete in foundation walls, which could lead to insufficient bearing of supported walls or eccentric loads on the foundation, which could lead to an inability to support gravity loads or lateral earth loads, which could lead to concrete cracking.

This is to limit the probability of compromised structural integrity, which could lead to:

• structural failure, or
• where elements support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

This is to limit the probability of harm to persons.
