Intent

Intent 1:

To limit the probability of:

  • ice lens formation beneath the foundations of regularly occupied buildings, which could lead to the displacement of foundation elements, or
  • the displacement of relatively massive concrete steps due to frost.

This is to limit the probability that foundations will crack, which could lead to compromised structural integrity of elements supported by foundations, which could lead to:

  • an inability to support vertical building loads or lateral earth loads, or
  • for environmental separators or elements supporting an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

This is to limit the probability of harm to persons.
