Limitations to this advice
Foundation and geotechnical engineering problems are a principal cause of construction delays, cost overruns,
claims and disputes. The following information is provided to help you to understand this report and its
limitations and manage your risks.

Scope and Applicability of this Report
This report has been prepared for a specific purpose and scope and its applicability is limited. CGC cannot
accept any responsibility for the use of this report outside of the stated scope and purpose. If a service has not
been explicitly included in the scope, it must be assumed that it has not been provided. Assessment of soil or
groundwater contamination does not form part of this geotechnical report and any reference to any potential
site contamination is for information only. If you are uncertain about the applicability of the results for any
particular purpose, you should consult CGC to avoid any misunderstanding or miss-application.
This report has been prepared for the nominated Client and project only and should not be relied upon by
other parties, or for other purposes, without consulting CGC. Any party relying on this report beyond its
specific purpose and scope does so entirely at their own risk and responsibility. CGC does not take
responsibility for the use of this document by any other person or party than the Client.

Project Details and Information Provided
This report has been based on project details as provided to us at the time of the commission. We have
assumed that the information supplied to CGC by the client or other external sources on behalf of the client, is
correct unless explicitly stated so. CGC does not accept any responsibility for incomplete or inaccurate data
provided by others.
If any project details change during the course of the project or observed conditions are considered to differ
from those expected or assumed, CGC should be notified in order to investigate if and how changes in project
details affect the conclusions and recommendations in our report. If CGC is not consulted when changes are
made to the initial project details, we cannot accept any responsibility for problems arising from these
changes.

Geotechnical Information and Interpretation
Site investigations only sample discrete parts of the ground, and that extrapolation and interpolation of
collected information can be used with varying degrees of risk and uncertainty depending on the extent and
quality of the site investigation, the variability of the subsurface conditions and the consequences to the
proposed works.
The analyses and recommendations in this report rely on the results of site investigation information, and
other reported geotechnical information that is relevant to the works. This may include the results of pile load
testing, other geotechnical testing, and inspections and observations from studies that have been performed
as part of the works or in the vicinity of the works previously.
We have endeavoured to incorporate the available information into an appropriate geotechnical model based
on our interpretation of the likely subsurface conditions. This process, and the geotechnical analysis and
interpretation based on that model, is an inexact science, as a model is but a simplification of reality to derive
a geotechnical solution. While we endeavour to incorporate realistic model parameters, our models,
interpretations and the outcomes or our work generally may differ from reality for a range of reasons
including:
     • Spatial Variability: Geotechnical and geological variability across the site which may not have been
          captured in the site investigation works that have been used in our works. Geotechnical site
          investigations are very limited in the extent of physical investigation compared to the size of the
          entire site. No site investigation, no matter how comprehensive, can reveal all subsurface details and
          anomalies and conditions that differ from those observed in the site investigation will occur;
     • Temporal Variability: Subsurface conditions can change with time due to man-made events such as
          cutting or filling or any construction works on or adjacent to the site which can also affect the site
          drainage and hence underlying properties; or by natural events such as floods or groundwater
          fluctuations.
