1dentify any statutory and consultative processes associated with the geotechnical
works necessary to ensure the timely implementation of the project (e.g.
geotechnical submission to the Geotechnical Engineering Office). 1f instructed
by the Employer, make the submissions to obtain the necessary
approval/acceptance.
Based on the available information:
(i)
(ii)
rank the alternative alignments/design options based on the magnitude of
the geotechnical hazards present along each proposed alignment and/or
associated with each design option, and
recommend the appropriate rating to be used for the geotechnical factors
in the overall highway alignment/design option evaluation process.
C.3 Deliverables
The Consultants shall produce:
(a)
(b)
(c)
(d)
A Desk Study Report which shall document the information examined and work
carried out in C.2(a) and C.2(b) above, with Geotechnical 1nformation Unit
(G1U) references where appropriate, and describe the geological setting of the
preferred route. Where necessary, a ground investigation (G1) plan as stated in
C.2(d) above shall also be prepared.
A G1 Review Report documenting the findings, interpretation and conclusions of
the walkover survey carried out in C.2(c) above and the G1, including any field
testing, laboratory testing and groundwater and other monitoring works carried
out in C.2(e) above, making reference to any G1 contractor and laboratory testing
reports produced, and making recommendations on any supplementary G1 works
needed for detailed design or additional G1 works required during construction.

the solid and superficial geology along the highway route,
the locations of exposures of soil and rock, annotated with key
information about the nature of the materials,
areas of past instability, e.g. landslide scars, boulder/rock fall locations,
annotated with key information about the nature of the instability,
drainage courses and information on any areas of seepage observed,
existing man-made slope features, and
