| Objective | OH4 Vibration and Deflection Limitation |
| Attribution | |
| Application | Application 1: Design capacity of foundations,
in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where the foundation bears on gravel, sand or silt, and the water
table is within a distance below the bearing surface equal
to the width of the foundation. |

| Intent | Intent 1: For coarser soil types near the footings' bearing surface
(for which free water between soil particles can reduce bearing capacity),
to limit the probability of excessive soil subsidence, which could lead to
the cracking of foundations or building superstructures. 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 of floors, which
could lead to negative effects on the psychological well-being of persons.
