Application
Application 1: 
Load factor for the dead load for soil, superimposed earth, plants and trees on buildings.
This applies to buildings described in Sentence 1.3.3.2.(1) of Division A and to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] that are required to be designed in accordance with the requirements of Part 4.

Intent
Intent 1: 
To limit the probability that dead load due to soil, superimposed earth, plants and trees will not be taken into account in the structural design, with respect to how these loads impact on the total load, which could lead to the excessive deformation of, or excessive stress in, structural components, which could lead to damage to the building.
Intent 2: 
To allow a reduction in the dead load factor for soil, superimposed earth, plants and trees, where the depth of the soil is greater than 1.2 m, on the basis that a slight variation in the depth will not have as big an impact on the total load.
