Intent
Intent 1: 
To limit the probability that the foundations will be displaced due to hydrostatic uplift, either during construction or during the life of the building, 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.
