ATTRIBUTION:

Functional Statement:

F21

To limit or accommodate dimensional change.

Objective:

OS2.3

 

APPLICATION:

Depth of foundations for carports or garages connected to a dwelling unit directly or by a breezeway and serving not more than one dwelling unit, where such foundations are built in clay-type soils subject to significant movement with a change in soil moisture content, for buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

INTENT:

To limit the probability of differential vertical movement of soil beneath and between the foundations of dwelling units and the foundations of structurally-attached garages or carports, which could lead to damage to foundations.
This is to limit the probability of an inability to support vertical building loads or lateral earth loads, which could lead to:
  • structural failure, or
  • compromised structural integrity of elements supported by foundations, which could lead to the failure of environmental separation elements, which could lead to the deterioration of building elements.
This is to limit the probability of harm to persons.

APPLICATION:

Depth of foundations for carports or garages connected to a dwelling unit directly or by a breezeway and serving not more than one dwelling unit, where such foundations are built in clay-type soils subject to significant movement with a change in soil moisture content, for buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

INTENT:

To limit the probability of differential vertical movement of soil beneath and between the foundations of dwelling units and the foundations of structurally-attached garages or carports, which could lead to damage to foundations.
This is to limit the probability of:
  • the ingress of pollutants from the exterior, including soil gas, combustion products from parking garages, and particulates,
  • the ingress of precipitation,
  • condensation, or
  • the ingress of moisture from the ground.
This is to limit the probability of:
  • an inadequate control of the temperature of interior spaces 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 or of elements protected by the 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.

This is to limit the probability of:
  • the space being unsuitable for its intended use,
  • compromised operation of doors or windows, or
  • damage to the building.
