Intent 1:
To limit the probability of insufficient reinforcement
around openings or that reinforcement around openings will not be
adequate to ensure a bond develops between the concrete and the reinforcement,
which could lead to loads not being transferred across openings, which
could lead to concrete cracking or the displacement of foundation
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 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.
