Intent 1:

To limit the probability of failure of the foundation wall at the point of stair attachment due to dead and live loads imposed by stairs and users, which could lead to concrete cracking, which could lead to:

  • 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, water ingress and 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 elements supported or protected by foundations.

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.
