9.4.4.6.(2)

Intent 1:

To limit the probability that any surcharge on 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, or
• 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.

This is to limit the probability of harm to persons.

Intent 2:

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.
