Intent 1:
To limit the probability of insufficient reinforcement
or that reinforcement across a cold joint will not be adequately bonded
to the concrete, which could lead to tension loads not being transferred
to each side of the joint, 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.
