Notes: * - Fb = Ultimate End Bearing Pressure (unfactored) for long piles, Fs = Ultimate Shaft Adhesion (unfactored).




The upper 1 m of soil profile should be ignored in shaft calculations to allow for shrinkage
cracks. The values presented in Table 3 assume that the material equal to four pile diameters
below the base of any footings is as strong or stronger.


Settlement values are subjected to a variety of factors; however, a properly designed and
constructed pile should have a serviceability settlement between 1% and 2% of its’ diameter.


9.0 Limitations
Arcos Unit Group Pty Ltd (AG) has prepared this document for 20 Park Crescent, Sunshine Beach
for Teeland Architects. The document is specific to this particular project and for the purposes
as described within the document. The document cannot be used for any other project on the
same site or other sites or relied upon by a third party. Any party relying upon this document
beyond its exclusive use and purpose as stated above, and without the express written consent
of AG, does so entirely at its own risk and without recourse to AG for any loss or damage. AG
has necessarily relied upon information provided by the client and/or their agents.

It is important to understand that ground conditions can be spatially variable over short
distances as a result of geological processes or human interference. These changes can occur
after the time of which field work was undertaken. Given this, the assumed subsurface
conditions within this document are only indicative of the conditions at the testing locations
to the depths investigated at the time of the fieldwork.

The advice given in this document is based upon the assumed subsurface conditions. The
relevance and accuracy of advice given is directly affected by variations in ground conditions
across the site between testing locations that has not been captured and time elapsed since
investigation works.

This document must be kept in entirety, read in full and understood. Interpretations or
conclusions made by others unless supported by an expressed written statement,
interpretation, outcome or stated within this document cannot be the responsibility of AG.

This document or parts of it should not be used as part of a specification or design for a project
without prior review and agreement by AG.
