9.23.2.2.(1)

Intent 1:

To limit the probability of inadequate moisture resistance or inadequate provision for drying, which could lead to extended exposure to surface water or to water from the ground transferred through masonry or concrete, which could lead to wood decay, which could lead to an inability to resist expected gravity or lateral loads, which could lead to excessive movement, deflection or deformation.

This is to limit the probability of:

• compromised structural integrity,
• where members support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration, or
• an inability to resist expected loads, which could lead to:
  • the excessive deflection or vibration of floors, or
  • the excessive movement or deformation of walls.

This is to limit the probability of:

• compromised operation of doors or windows required for egress in an emergency, and
• persons losing their balance, tripping or falling.

This is to limit the probability of harm to persons.
