Back9.3.2.9.(1)

ATTRIBUTION:

Functional Statement:

F82

To minimize the risk of inadequate performance due to improper maintenance or lack of maintenance.

F80

To resist deterioration resulting from expected service conditions.

Objective:

OS2.3

 

APPLICATION:

Structural wood elements, in localities where termites are known to occur, with respect to:
  • the resistance of structural wood elements to termites,
  • clearances between structural wood elements and the ground immediately below them, and
  • the visibility of supporting elements.
This applies to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

INTENT:

To limit the probability of an inadequate resistance to termites or an inability to detect and mitigate termite infestations, which could lead to damage to wood elements, which could lead to an inability to resist expected gravity or lateral loads.
This is to limit the probability of compromised structural integrity, which could lead to:
  • structural failure, or
  • where wood elements support or are used in 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.

This is to limit the probability of compromised structural integrity, which could lead to:
  • structural failure,
  • where structural wood elements support or are used in an environmental separator, 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,
  • compromised operation of windows and doors, and
  • damage to the building.

  • the resistance of structural wood elements to termites,
  • clearances between structural wood elements and the ground immediately below them, and
  • the visibility of supporting elements.

INTENT:

To limit the probability of an inadequate resistance to termites or an inability to detect and mitigate termite infestations, which could lead to damage to wood elements, which could lead to an inability to resist expected gravity or lateral loads.
Where structural wood elements support or are used in an environmental separator, this is to limit the probability of compromised performance of the building envelope, which could lead to:
  • condensation,
  • precipitation ingress, or
  • compromised thermal performance of components intended to provide resistance to heat transfer.
This is to limit the probability of:
  • an inadequate control of indoor air and surface temperatures, drafts, relative humidity, or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable upon wetting, or
  • deterioration, which could lead to further compromised integrity of environmental separators.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.
This is to limit the probability of harm to persons.
