| Application | Application 1: Vertical reinforcement in flat insulating concrete
form walls not in contact with the ground, in buildings to
which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9], where:
Exceptions:
except as stated in Sentence 9.20.1.1.(2), which applies to

| Intent | Intent 1: To limit the probability that the placement or amount and
spacing of vertical reinforcement will not be adequate to ensure the reinforcement
is encased and bonded to the concrete, which could lead to an inadequate resistance
to expected loads, which could lead to concrete cracking or the displacement
of walls. This is to limit the probability of:
For floors and elements supporting floors, this is to limit the
probability of excessive movement, deflection or vibration, which could lead
to negative effects on the psychological well-being of persons.
