Intent 1:
To limit the probability of excessive eccentricity
of loads, which could lead to masonry cracking or falling.
This is to limit the probability of:
- compromised structural integrity of masonry construction,
- where masonry construction is part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to deterioration, or
- an inability to resist expected loads, which could lead
to:
- the excessive movement or deformation 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,
- compromised operation of windows or doors, or
- damage to the building.
Intent 2:
To clarify the method for measuring the projection,
beyond its supporting base, of rough-stone veneer where the face is
not coplanar.
