Intent 1:
To limit the probability of insufficiently thick
concrete footings, which could lead to:
- drying before hydration is complete, or
- inadequate shear strength.
This is to limit the probability of weak concrete, which
could lead to shear failure under gravity loads transmitted through
foundation elements, which could lead to excessive settlement of the
soil and structural damage to the foundation and the building.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure,
- where elements support or are part of 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.
