wood-frame or masonry construction to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

| Intent | Intent 1: To limit the probability of inadequate crack control, which
could lead to random cracking of cast-in-place and concrete block foundation
walls due to shrinkage or soil movement, which could lead to water ingress,
which could lead to compromised structural integrity of elements supported
by foundations, which could lead to the displacement or failure of required
environmental separation elements, which could lead to the deterioration of
building elements, which could lead to harm to persons. |
