OS2 Structural Safety


[F81-OS2.3]Applies to elements that support or are part of an environmental separator.


Intent 1:

To limit the probability that improperly placed backfill will lead to damage or displacement of foundation elements.

This is to limit the probability of compromised structural integrity of elements supported by foundations, which could lead to:

  • an inability to support vertical building loads or lateral earth loads, or
  • for environmental separators or elements supporting 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.
