PREFACE
This Standard was pre pare d by the Standards Australia Committe e CE-018, Piling, to
superde AS 2159—1995.
The objective of this Standard is to provide requirements for design and installation of piles
for supporting structur e s. Th e obj e ct of this r e vision is to align with updat e d
AS 1170 Standards and reflect changes in practice since the previous edition.
Major changes to the previous edition are as follows:
(a) Revision of the overall Standard.
(b) Re vision of the tting of stre ngth re duction factors, that is, the le ction of the
‘safety’ level appropriate to the installation being designed.
(c)
Revision of the negative skin friction requirements. (d) Revision of durability requirements to assist designers to achieve predicted life.
(e ) Include re quire me nts for ne we r pile type s and installation me thods including ste e l
screw piles, jacking, screwing and screwed cast in place.
(f)
Requirement for some testing to be ‘normative’. (g) Inclusion of new types of test including rapid pile testing.
The te rms ‘normative ’ and ‘informative ’ have be e n u d in this Standard to de fine the
application of the appendix to which they apply. A ‘normative’ appendix is an integral part
of a Standard, whereas an ‘informative’ appendix is only for information and guidance.
Statements expresd in mandatory terms in notes to tables are deemed to be requirements
of this Standard.
Notes to the text contain information and guidance and are not considered to be an integral
part of the Standard.
