Intent 1:

To limit the probability of the cracking of foundations or building superstructures.

This is to limit the probability of:

• compromised structural integrity, or
• for environmental separators or elements supporting environmental separators, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements, which could lead to compromised structural integrity.

For floors and elements supporting floors, this is to limit the probability of excessive movement, deflection or vibration of floors, which could lead to negative effects on the psychological well-being of persons.
