To limit the probability that any surcharge on the
foundation walls will not be included in the design pressures, which
could lead to the walls being unable to resist lateral pressure, which
could lead to the cracking of foundations or building superstructures.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure,
- for environmental separators or elements supporting
environmental separators, the displacement or failure of required
environmental separation elements, which could lead to the deterioration
of building elements, which could lead to further compromised structural
- an inability to resist expected loads, which could lead
- 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.
To expand the application of Section 4.2. to walls supporting other than drained earth
that are not constructed in accordance with Section 9.15.
