Appendix4-SlopeStabilityAssessment · MCU18/0135

Introduction

The purpose of this report is to classify the site in accordance with AS2870-2011. This
report is based on the field investigation/lab testing and information if any provided by the
client. Further investigation may be required. Further investigation is recommended when
deeper depths of fill or marine clays are thought to be present.




Site Classification




                   Class “P” (Due to poor bearing capacity)

      Based on the soil profiles the site would have the
characteristics of an 'S' site with a approximate Ys of less than
                        20mm if not a “P”.


This report does not address slope stability, if a slope stability report is required the services
              of a suitably qualified Geotechnical Engineer should be sought.


 This site may experience settlement in the fill and/or underlying natural material and may
  have deep settling marine clays present, the designing engineer should allow for this.


Allowable Bearing Capacity

An approximate bearing capacity of 100kpa was encountered at a depth of 2700mm
below existing ground surface level in the SAND at location BH1 and location BH2.

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. Soft and/or
settling soils may present within the investigated depths or at deeper depths, further
investigation may be required to establish this.
