Intent 1:
To limit the probability that the placement or amount
and spacing of vertical reinforcement will not be adequate to ensure
the reinforcement is encased and bonded to the concrete, which could
lead to an inadequate resistance to expected loads, which could lead
to concrete cracking or the displacement of walls.
Where elements support or are part of an environmental separator,
this is to limit the probability of:
- condensation,
- rainwater ingress,
- the ingress of moisture, 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
- 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.
