Application
Application 1: 
Assessing the condition of the foundations supporting buildings, where deep foundation units have not been placed within the permissible deviations referred to in Article 4.2.7.3.
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 an installed deep foundation unit, with deviations in alignment and location outside those assumed for its design, will undergo a large deformation under the expected loads, which could lead to excessive displacement of the foundation, which could lead to:
  • damage to the building, and
  • excessive distortion of the building, which could impede the use and occupancy of the building.
Intent 2: 
To direct Code users to the requirement of Article 2.2.4.7. of Division C concerning the recording of alterations on the design drawings.
