OP2 Structural Sufficiency of the Building

Intent

Intent 1:

To limit the probability of ice lens formation beneath foundations that are installed on fine-grained soils (which can retain quite a bit of water), which could lead to the excessive vertical movement of the soil, which could lead to excessive stress on foundations, which could lead to structural damage to foundations and superstructures.

This is to limit the probability of compromised structural integrity, which could lead to:

  • structural failure,
  • 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, or
  • an inability to resist expected loads, which could lead to
    • the excessive deformation or deflection of walls, or
    • the excessive deflection or vibration of floors.

This is to limit the probability of:

  • the space being unsuitable for its intended use, or
  • damage to the building.
