SUMMARY OF REPORT

Work undertaken

9 A marine geotechnical site investigation, scoped and specified by

WorleyParsons, was undertaken in Lyttelton Harbour to assess the

engineering geological conditions within the areas of proposed

future dredging. The primary site investigation methods comprised

CPTu’s and boreholes, which were performed with conventional

borehole drilling and CPT equipment mounted on a self-elevating /

jack-up barge.

10 The geotechnical site investigation was performed in three separate

phases scheduled around logistical and operational constraints. The

first phase was performed between 2 October and 4 November

2016. The second phase was performed between 22 November and

6 December 2016 and the third phase was performed between 17

and 27 February 2017.

11 The site investigation scope comprised ‘paired’ CPTu’s and boreholes

at 20 test locations positioned throughout the areas of proposed

future dredging in Lyttelton Harbour, including areas of proposed

deepening and widening of the existing channel and along the

alignment of the proposed channel extension (Figure 1,

Attachment 1). The CPTu’s and boreholes were specified with a

nominal target depth of -20 m Chart Datum (mCD), therefore

extending several meters below the future target depth of dredging

and allowing for characterisation of the dredge materials including

over-dredge within normal dredging tolerances.

12 CPTu’s were performed in general accordance with ASTM D5778-12

“Standard Test Method for Electric Friction Cone and Piezocone

Penetration Testing of Soils”. Specification of intervals and

durations for in-situ dissipation testing was performed on-board the

jack-up barge by an experienced Engineering Geologist from

WorleyParsons / Advisian.

13 Specification of sampling intervals, in-situ testing intervals and

geotechnical logging of the boreholes was carried out on-board the

jack-up barge by an experienced Engineering Geologist from

WorleyParsons / Advisian. Logging was performed in general

accordance with:

4

100081355/947213.3

13.1 Australian Standard (AS) 1726-1993 “Geotechnical site

investigations”; and

13.2 New Zealand Geotechnical Society (NZGS) “Field Description

of Soil and Rock, Guideline for the Field Classification and

Description of Soil and Rock for Engineering Purposes”,

December 2005.

14 Subsequent to the site-based component of the investigation,

geotechnical laboratory testing was performed on selected soil

samples recovered from the boreholes. Samples were transported

to Perth, Australia where a laboratory testing programme

appropriate for assessment of dredging conditions was undertaken.

Specification of test types and intervals was scheduled by an

experienced Engineering Geologist from WorleyParsons / Advisian.

Individual tests were undertaken in accordance with relevant

Australian/New Zealand or international standards, where

applicable.

The results

15 The results of the investigation will be reported in a factual report

entitled “LPC Dredging Support, Geotechnical Site Investigation

Factual Report (Final)” reference number 301311-09433-GT-REP-

0001. At the time of preparation of this statement this report has

been issued in a ‘Preliminary’ form only, which was compiled

following completion of the second phase of the site investigation.

The Final report will be issued pursuant to incorporation of the

results of the third (and final) phase of the site investigation,

including receipt of all remaining laboratory testing data which is

currently pending completion by the testing laboratory.

16 In summary, the result of investigations so far have identified the

following soil conditions:

16.1 The marine subsurface geological profile within the depth of

the proposed future dredging is dominated by a sequence of

mostly medium to high plasticity Clayey Silts and Silty Clays

(‘loess’ soils), with a subordinate quantity of Sandy Silts.

These soils are predominantly very soft at the seabed and in

the shallow subsurface, grading to soft over the majority of

the proposed dredge depth, equating to an undrained shear

strength of less than 25 kPa. In some locations the soil

grades to firm at depths approaching the limit of proposed

future dredging, reaching a maximum undrained shear

strength of 33 kPa.

16.2 No evidence of cemented materials, rock, or ‘hard layers’ was

identified within the depth of proposed dredging during the

site investigation or subsequent laboratory testing.

5

100081355/947213.3

16.3 ‘Sandy’ soils of relatively high strength in comparison to the

predominant ‘loess’ soils where identified at all locations

investigated. The ‘sandy’ soils occur in a laterally continuous

horizon, but in all locations investigated were encountered at

depths below the proposed dredge levels.

16.4 Summary results of the complete set of CPTu data for all

three phases of the site investigation are included as

Attachment 2.

CONCLUSION

17 The geotechnical site investigation activities completed in this study

have expanded on the existing data sets to provide a more complete

coverage and understanding of the materials which may be

encountered during the future dredging operations.

18 Geotechnical investigations identified a profile of low strength clayey

and silty soils, which are expected to be suitable for dredging with

conventional dredging equipment.

CPT CALIBRATION AND TECHNICAL NOTES

These notes describe the technical specifications and associated calibration references pertaining to the following cone types:

I-CFXY-10 measuring cone resistance, sleeve friction and inclination (standard cone, 10cm²);

I-CFXY-15 measuring cone resistance, sleeve friction and inclination (standard cone, 15cm²);

I-CFXYP20-10 measuring cone resistance, sleeve friction, inclination and pore pressure (piezocone, 10cm²);

I-CFXYP20-15 measuring cone resistance, sleeve friction, inclination and pore pressure (piezocone, 15cm²);

I-C5F0p15XYP20-10 measuring sensitive cone resistance, sleeve friction, inclination and pore pressure (piezocone, 10cm²).

Dimensions

Dimensional specifications for all cone types are detailed below. All tolerances are routinely checked prior to testing and

measurements taken are manually recorded on CPT field sheets. All field sheets are kept on file and available on request.

Cone area ratio

α = A / B = 0.75

β = 1 - A / B = 0.25

CPT CALIBRATION AND TECHNICAL NOTES (cont.)

Calibration

Each cone has a unique identification number that is electronically recorded and reported for each CPT test. The identification number enables the operator to compare ‘zero-load offsets’ to manufacturer calibrated zero-load offsets.

The recommended maximum zero-load offset for each sensor is determined as ± 5% of the nominal measuring range.

In addition to maximum zero-load offsets, McMillan Drilling also limits the difference in zero load offset before and after the test as ± 2% of the maximum measuring range. See table below:

Tip (MPa)

Friction (MPa)

Pore Pressure (MPa)

Maximum Measuring Range: 150 1.50 3.00

Nominal Measuring Range: 75 1.00 2.00

Max. ‘zero-load offset’: 7.5 0.10 0.20

Max ‘before and after test’: 3 0.03 0.06

Note: The zero offsets are electronically recorded and reported for each test in the same units as that of

each sensor.
