Intent 1:
To limit the probability of the removal or disturbance
of an excessive volume of soil from slopes, which could lead to the
destabilization and failure of slopes, which could lead to structural
damage to the foundation and the building, which could lead to an
inability to support vertical building loads or lateral earth loads.
Where elements support or are part of an environmental separator,
this is to limit the probability of concrete or masonry cracking,
which could lead to:
- condensation,
- rainwater ingress,
- the ingress of moisture from the ground, or
- compromised thermal performance of components intended
to provide resistance to heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures of interior spaces,
relative humidity, or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- compromised integrity of elements supported by foundations,
which could lead to the deterioration of building elements.
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.
