OS2 Structural Safety


(a) [F60-OS2.1]
(a) [F60-OS2.3]Applies where foundations serve as or support an environmental separator.


Intent 1:

To limit the probability of inadequate drainage, which could lead to a perched water table, which could lead to the accumulation of water under hydrostatic pressure, which could lead to excessive moisture loading on foundation walls.

This is to limit the probability of:

  • water ingress, or
  • excessive lateral loading on foundation walls, which could lead to the movement or cracking of foundations or building superstructures.

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

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

This is to limit the probability of harm to persons.
