Application | Application 1: Dimensions of reduced sections of solid concrete and
unit masonry foundation walls that are installed
on soils having an allowable bearing pressure of 75
kPa or greater, where the tops of the walls are reduced in thickness
to permit the installation of floor joists, for buildings of

Intent | Intent 1: To limit the probability of excessive height or inadequate
thickness of thin portions of concrete or unit masonry foundation walls, which
could lead to inadequate strength, which could lead to an inability to support
expected vertical loads, which could lead to structural damage to the foundation
and the building. This is to limit the probability of
compromised structural integrity, which could lead to:
This is to limit the probability of harm to persons.
