Sentence 4.2.4.12.(1)

Intent 1:

To limit the probability that the design of foundations, including ground floors, will not take into account the dimensional changes in rock materials, for example due to moisture changes or stress release, which could lead to excessive displacement of ground, which could lead to:

• damage to the building, and
• excessive distortion of the building, which could impede the intended use and occupancy of the building.
