Western Australia Chapter

Some Geotechnical Challenges

Dr Peter W. Mitchell

This presentation will discuss a number of challenging geotechnical issues relating to footing design that the speaker has observed over the course of his career.

These issues include:

  • collapsing soils;
  • residential type footing designs in arid areas;
  • the special geotechnical considerations associated with jacked piling leading to the incorporation of several aspects of jacked piling into AS 2159-2009 “Piling- Design and installation” code; and
  • the difficulties of Standard Penetration Testing (SPT) in saturated sand.

Engineers Australia members participating in AGS technical sessions can record attendance on their personal CPD logs. Members should refer to Engineers Australia CPD policy for details on CPD types, requirements and auditing guidelines.
