Intent

Intent 1:

To limit the probability that a foundation unit will not be designed for frost action expected to occur below the foundation, which could lead to excessive upward displacement of the unit, 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.

Intent 2:

To exempt from the application of Sentence 4.2.4.4.(1) foundations where conditions are such that they are unlikely to be negatively affected by frost action.
