Intent 1:
To limit the probability of unlevel surfaces underlying
sill plates, which could lead to discontinuous support for sill plates,
which could lead to an inability to resist expected gravity or lateral
loads, which could lead to excessive deflection or failure of sill
plates.
This is to limit the probability of compromised
structural integrity, which could lead to:
- the structural collapse of wood-frame construction,
or
- where wood-frame construction supports or is part of
an environmental separator, the excessive deformation, displacement
or failure of required environmental separation elements, which could
lead to deterioration, which could lead to further compromised structural
integrity.
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.
