Factual GI Report An Daingain Navagation Channel 19-12-16 Ground Investigation Report

Ground Investigations Ireland Ltd 3

1.0 Preamble

On the instructions of the Department of Agriculture, Food and the Marine (DAFM) and Nicholas O’ Dwyer

Consulting Engineers, a site investigation was carried out by ABCO Marine and Ground Investigations

Ireland Ltd., between September and October 2016 at various locations within An Daingean Fisher Harbour

and the proposed navigation channel.

2.0 Overview

2.1. Background The works are proposed to provide geotechnical information required for the design for dredging works to

the channel and turning basin. The works comprise 26 marine boreholes (permanently immersed) together

with associated in-situ and laboratory testing.

The site is currently a busy fishery harbour and is situated in the Centre of An Daingean in Co. Kerry. A

significant dredging programme is also envisaged and a programme of environmental sampling and

analysis has been carried out to facilitate the disposal of any excavated material.

The ground investigation originally comprised 26 no. Marine Boreholes however was amended to comprise

an additional 3 no. Marine Boreholes completed using rotary core drilling only. A series of grab samples

were recovered from 9 no. locations within the harbour to collect sediment samples for environmental

analysis. The boreholes were drilled with Cable Percussion techniques with Rotary Core Follow-on from

the Jack-up barge provided by ABCO Marine.

2.2. Purpose and Scope

The purpose of the site investigation was to investigate subsurface conditions utilising a variety of

investigative methods in accordance with the project specification. The scope of the work undertaken for

this project included the following:

Visit project site to observe existing conditions

Mobilise Jack-up Barge and support vessels for the proposed investigation

Carry out 9 No. Surface Grab Samples to recover sediment samples

Carry out 26 No. Cable Percussion Boreholes to recover sediment samples & insitu testing

Carry out 29 No. Rotary Core Boreholes to recover rock core samples for logging & testing

3.0 Subsurface Exploration

3.1. General

During the ground investigation a programme of intrusive investigation specified by the Consulting Engineer

was undertaken to determine the sub surface conditions at the proposed site. Regular sampling and in-

situ testing was undertaken in the exploratory holes to facilitate the geotechnical descriptions and to enable

laboratory testing to be carried out on the soil samples recovered during excavation and drilling.

The procedures used in this site investigation are in accordance with Eurocode 7 Part 2: Ground

Investigation and testing (ISEN 1997 – 2:2007) and B.S. 5930:2015.

3.2. Grab Sampling

The grab sampling was carried out at the locations shown in the location plan in Appendix 1 using a Van

Veen stainless steel grab sampler. Geotechnical or environmental soil samples can be recovered from each

of the samples following logging. The grab sample records are provided in Appendix 2 of this Report.

3.3. Cable Percussion Boreholes

The Cable Percussion Boreholes were drilled using a Dando 2000 drilling rig with regular in-situ testing and

sampling undertaken to facilitate the production of geotechnical logs and laboratory testing. Where bedrock

was shallow the Cable Percussion boring was completed utilising the winch on the T44 Beretta which

subsequently followed on down the same hole to complete the rotary core drilling.

The standard method of boring in soil for site investigation is known as the Cable Percussion method. It

consists of using a Shell in non cohesive soils and a clay cutter in cohesive soils, both operated on a wire

cable. Very hard soils, boulders and other hard obstructions are broken up by chiselling and the fragments

removed with the Shell. Where ground conditions made it necessary, the borehole was lined with 200mm

diameter steel casing. While the use of the Cable Percussion method of boring gives the maximum data

on soil conditions, some mixing of laminated soil is inevitable. For this reason, thin lenses of granular

material may not be noticed.

Disturbed samples were taken from the boring tools at suitable depths, so that there is a representative

sample at the top of each change in stratum and thereafter at regular intervals down the borehole until the

next stratum was encountered. The disturbed samples were then sealed and sent to the laboratory where

they were visually examined to confirm the description of the relevant strata.

Standard Penetration Tests were carried out in the boreholes. The results of these tests, together with the

depths at which the tests were taken are shown on the accompanying borehole records. The test consists

of a thick wall sampler tube, 50mm external diameter, being driven into the soil by a monkey weighing

63.5kg and with a free drop of 760mm. For gravels and glacial till the driving shoe was replaced by a solid

60º cone.

The Standard Penetration Test number referred to as the ‘N’ value is the number of blows required to drive

the tube 300mm, after an initial penetration of 150mm. The number gives a guide to the consistency of the

soil and can also be used to estimate the relative strength/density at the depth of the test and also to

estimate the bearing capacity and compressibility of the soil.

The cable percussion borehole logs are provided in Appendix 3 of this Report.

3.4. Rotary Boreholes

The rotary coring was carried out by a track mounted T44 Beretta rig at the locations shown on the location

plan in Appendix 1. The rotary boreholes were completed from the base of the cable percussion borehole

where the casing was left as a temporary liner to facilitate follow-on rotary coring.

The T44 Beretta is equipped with rubber tracks which allow for short travel on pavement surfaces avoiding

any damage to the surface. The T44 Beretta utilises a triple tube core barrel system operated using a

wireline drilling process. The outer barrel is rotated by the drill rods and at its lower end, carries the coring

bit. The inner barrel is mounted on a swivel so that it does not rotate during the process. The third barrel or

liner is placed within the second one to retain the core intact and to preserve as much as possible the fabric

of the drilling stratum. The core is cut by the coring bit and passes to the inner liner. The core is brought

up to the surface within the inner barrel on a small diameter wire rope or line attached to the “overshoot”

recovery tool which is then placed into a core box in order of recovery. A drilling fluid, typically air mist or

water flush is passed from the surface through hollow drill rods to the drill bit, and is used to cool the drill

bit. Temporary casing is used in some situations to support unstable ground or to seal off fissures or voids.

It should be noted that the rotary coring can only achieve limited recovery in overburden, particularly

granular or weakly cemented strata due to the flushing medium washing away the cohesive fraction during

coring. The recovery achieved, where required is noted on the borehole logs and core photographs are

provided to allow assessment of the core recovered. The rotary borehole logs are provided in Appendix 4

of this Report.

3.5. Surveying

Each of the exploratory hole locations have been set out and recorded using a Trimble R10 GNSS System

which records the coordinates and elevation of the locations to ITM or Irish National Grid as required by the

project specification. The coordinates and elevations are provided on the exploratory hole logs in the

appendices of this Report.

3.6. Laboratory Testing

Samples were selected from the exploratory holes for a range of geotechnical and environmental testing to

assist in the classification of soils and to provide information for the proposed design.

Environmental testing which consisted of a suite specified by the Marine Institute. The testing was carried

out by Jones Environmental Laboratory in the UK.

Geotechnical testing consisting of moisture content, Atterberg limits, Particle Size Distribution (PSD),

hydrometer, have been schedule with NMTL’s Geotechnical Laboratory in Carlow.

Rock strength testing including Point Load (Is50) Unconfined Compressive Strength (UCS)and cherchar

abrasivity testing has been completed with GSTL’s Laboratory in the UK. Selected samples were sent to

Sandbergs in London for Petrographic Analysis to assess the quartz content of the core at selected

locations.

The results of the environmental laboratory testing are included in Appendices 5 of this report. The results

of the geotechnical and rock strength testing are included in Appendix 6 and 7 of this Report.
