Intent 1:
To limit the probability of the improper installation
or excessive spacing of piers, which could lead to the overloading
and failure of individual piers, which could lead to an inability
to resist vertical building loads or lateral loads.
Where elements support or are part of an environmental separator,
this is to limit the probability of compromised integrity of the superstructure,
which could lead to:
- condensation,
- rainwater 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 temperatures of interior spaces,
relative humidity, or water ingress and accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- compromised integrity of elements supported by piers,
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.
