a ZoI line advised by Unitywater, such that the sewer line is not surcharged by the footings. In any event,
permission will need to be sought from Unitywater in relation to the proposed construction over their asset.



6.11 Site Maintenance
We recommend that where dilapidated log retaining walls are to remain that they be inspected by a
structural engineer and the walls strengthened or replaced as necessary.



6.12 Overall Effect of the Development on Stability
We do not consider that the development will have any detrimental impact on the stability of the site. This
is on condition that the design and construction of the proposed development refers to the geotechnical
advice presented in this report.



7    CONCLUSION
We consider the site is suitable for the proposed development on condition the advice contained in this
report is used.

The geotechnical advice presented in the preceding sections of this report are intended to achieve
“Acceptable” levels of risk 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 design and
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 advice presented in this report is 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 beyond the boreholes and DCP tests completed by ASI
and the DCP tests completed by JK Geotechnics 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.
