9.15.3.4.(3)

Intent 1:

To limit the probability of an inadequate footing width, which could lead to reduced friction among soil particles, which could lead to an inadequate bearing strength of the soil beneath the footings, which could lead to compressive failure and excessive settlement of the soil, which could lead to an inability to support vertical building loads or lateral earth loads.

This is to limit the probability of compromised structural integrity, which could lead to:

• structural failure,
• where elements support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements, or
• an inability to resist expected loads, which could lead to
  • the excessive deformation or deflection of walls, or
  • the excessive deflection or vibration of floors.

This is to limit the probability of:

• the space being unsuitable for its intended use, or
• damage to the building.
