Application
Application 1: 
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].
Exceptions: 
except as stated in Sentence 9.3.2.9.(2), which applies to the protection of assemblies supporting structural wood elements and their visibility.

Intent
Intent 1: 
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.
