OP2 Structural Sufficiency of the Building

Attribution

[F20-OP2.3]Applies to elements that support or are part of an environmental separator or are exposed to moisture.

Intent

Intent 1:

To limit the probability of discontinuity in mortar joints at either interior or exterior faces of hollow masonry units, which could lead to inadequate tensile and compressive strength of mortar joints.

This is to limit the probability of:

  • compromised structural integrity of masonry construction,
  • where masonry construction is part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration,
  • in assemblies exposed to moisture or the exterior, damage and deterioration, or
  • an inability to resist expected loads, which could lead to:
    • the excessive movement or deformation 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,
  • compromised operation of windows or doors, or
  • damage to the building.
