reduced. The bearing pressure should be selected so
altered significantly as a result of saturation, vibrations,
that the settlement of the mat foundation will be within

limits that the structure can safely tolerate as a flexible
settlement of these soils cannot be determined in the
structure. If settlements beneath the mat foundation are
