Objective

OS2 Structural Safety

Attribution

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

Intent

Intent 1:

To limit the probability of excessive soil settlement beneath foundation footings, which could lead to:

  • structural damage to foundations or damage to foundations' moisture-control elements, or
  • where settlement occurs at water-service locations, the rupture of water lines, which could lead to leakage and undermining of the foundation, which could lead to the structural failure of foundations and superstructures.

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.
