Intent 1:
To limit the probability of excessive soil settlement
beneath foundation footings, which could lead to:
- structural damage to foundations or damage to foundations'
moisture-control elements, or
- where settlement occurs at water-service locations,
the rupture of water lines, which could lead to leakage and undermining
of the foundation, which could lead to the structural failure of foundations
and superstructures.
At sewer-line and water-service locations, 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.
