Application
Application 1: 
Design of foundations where dynamic loading conditions apply.
This applies to buildings described in Sentence 1.3.3.2.(1) of Division A and buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A] that are required to be designed to the requirements of Part 4.

Intent
Intent 1: 
To limit the probability that the design of foundations will not take into account the dynamic loading applied to the foundation units, such as due to earthquake, which could lead to excessive displacement of the foundation, which could lead to damage to the building.
Intent 2: 
To limit the probability that the design of foundations will not take into account the dynamic loading conditions, which could lead to excessive movement of the foundation, which could lead to excessive distortion or vibration of the building, which could impede the use and occupancy of the building.
