OP2 Structural Sufficiency of the Building



Intent 1:

To limit the probability of a chemical reaction with concrete or mortar, which could lead to the premature failure of aluminum flashing.

This is to limit the probability of precipitation or meltwater ingress, which could lead to:

  • the deterioration of masonry due to freeze-thaw stresses, or
  • the deterioration of masonry elements, which could lead to compromised structural integrity.

This is to limit the probability of damage to the building.
