Intent 1:
To limit the probability of excessive soil settlement
beneath foundation footings, which could lead to:
- structural damage to foundations or damage to foundations'
moisture-control elements, or
- where settlement occurs at water-service locations,
the rupture of water lines, which could lead to leakage and undermining
of the foundation, which could lead to the structural failure of foundations
and superstructures.
This is to limit the probability of:
- condensation,
- precipitation 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 the temperature 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 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.
