Intent | Intent 1: To limit the probability of inadequate resistance to or
protection from surface water or water from the ground transferred by capillary
action through masonry or concrete, which could lead to wood decay, which
could lead to an inability to resist expected gravity or lateral loads.
For floors and constructions supporting floors, this is to limit
the probability of:
This is to limit the probability of excessive movement, vibration
or deflection of floors, which could lead to negative effects on the psychological
