Appendix B - Geotechnical Investigation Report

The geotechnical advice presented in the preceding sections of this report are intended to achieve
“Acceptable” levels of risk of instability of the site and to control future risks. The above recommendations
address geotechnical issues only and other conditions may be required to address other aspects.



8    GENERAL COMMENTS
The recommendations presented in this report include specific issues to be addressed during the
construction phase of the project. As an example, special treatment of soft spots may be required as a result
of their discovery during proof-rolling, etc. In the event that any of the construction phase recommendations
presented in this report are not implemented, the general recommendations may become inapplicable and
JK Geotechnics accept no responsibility whatsoever for the performance of the structure where
recommendations are not implemented in full and properly tested, inspected and documented.

Occasionally, the subsurface conditions between and below the boreholes and DCP tests completed by ASI
may be found to be different (or may be interpreted to be different) from those expected. Variation can also
occur with groundwater conditions, especially after climatic changes. If such differences appear to exist, we
recommend that you immediately contact this office.

This report provides advice on geotechnical aspects for the proposed civil and structural design. As part of
the documentation stage of this project, Contract Documents and Specifications may be prepared based on
our report. However, there may be design features we are not aware of or have not commented on for a
variety of reasons. The designers should satisfy themselves that all the necessary advice has been obtained.
If required, we could be commissioned to review the geotechnical aspects of contract documents to confirm
the intent of our recommendations has been correctly implemented.

A waste classification is required for any soil and/or bedrock excavated from the site prior to offsite disposal.
Subject to the appropriate testing, material can be classified as Virgin Excavated Natural Material (VENM),
Excavated Natural Material (ENM), General Solid, Restricted Solid or Hazardous Waste. Analysis can take up
to seven to ten working days to complete, therefore, an adequate allowance should be included in the
construction program unless testing is completed prior to construction. If contamination is encountered,
then substantial further testing (and associated delays) could be expected. We strongly recommend that this
requirement is addressed prior to the commencement of excavation on site.

This report has been prepared for the particular project described and no responsibility is accepted for the
use of any part of this report in any other context or for any other purpose. If there is any change in the
proposed development described in this report then all recommendations should be reviewed. Copyright in
this report is the property of JK Geotechnics. We have used a degree of care, skill and diligence normally
exercised by consulting engineers in similar circumstances and locality. No other warranty expressed or
