9.4.4.4.(1)

Objective

OP2 Structural Sufficiency of the Building

Attribution

[F21-OP2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability that moisture-content-related soil movement, frost heave, pressure due to the formation of ice lenses, adfreeze, and weathering of pyritic material will lead to the cracking of foundations or building superstructures.

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

  • structural failure,
  • 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 further compromised structural integrity, or
  • an inability to resist expected loads, which could lead to
    • the excessive deformation or deflection of walls, or
    • the excessive deflection or vibration of floors.

This is to limit the probability of:

  • the space being unsuitable for its intended use, or
  • damage to the building.
