Introduction

The purpose of this report is to classify the site in accordance with AS2870-2011. This report
is based on the field investigation/Iab testing and information if any provided by the client.
This report relates exclusively to the tested locations and the above-mentioned structure.
Further investigation may be required. Bore logging was carried out in accordance with
AS1726-2017 Geotechnical Site Investigations.

Site Classification

Class “P” (Due to uncontrolled fill, poor bearing capacity &
trees)

Based on the soil profiles the site would have the characteristics of
an 'H1' site with an approximate Ys of 40-45mm if not a “P”.

Important Notes Relating to the classification. Attached.

Allowable Bearing Capacity

An approximate bearing capacity of 100kpa was encountered as per the below:
* 1200mm below existing ground surface level in the Silty CLAY at BH1.
700mm below existing ground surface level in the Silty CLAY at BH2.

This is a suggested founding depth only, greater depth may be required due to the following.
Bearing capacity can be highly variable over the allotment these depths are specific to the
test locations. Actual founding depth should be nominated by the designing engineer whilst
taking construction and footing type, fill, underground services, retaining walls, settlement,
proposed cut/fill and any trees into account.
