  3. OH4
  4. OH1
  5. OP2

Objective

OS2 Structural Safety

Attribution

[F20,F21,F61-OS2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability that concrete block of inadequate compressive strength will be used, which could lead to:

  • an inadequate resistance to water absorption, which could lead to excessive water absorption, which could lead to blocks cracking due to freeze-thaw stresses, or
  • an inability to support loads, which could lead to blocks 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.
