Introduction
Pier and beam method of construction is usually considered when good bearing soil or strata is not located within 1.5 metres below the existing surface.
Most problem sites contain a problem area in the top layers of soil only. Often, good bearing soil is located at a specific depth below the natural ground level. The depth at which this good bearing soil is located will determine:
- the structural footing design
- the cost of the footing construction.
Pier and beam footings can be constructed in a variety of configurations. Two are:
- bulk pier and beam
- bored pier and beam.
