1. INTRODUCTION

This investigation was carried out by CC Ground Investigations Ltd (CCGI) on the

instruction and on behalf of Oxfordshire County Council (The Client) under the

technical direction of Atkins (the Engineer).

The purpose of the ground investigation was to provide information to assist in the

design of a new road and roundabout layout at Harwell.

This report describes the work carried out by CC Ground Investigations Ltd and

presents the findings.

All information, comments and opinions given in this report are based on the

ground conditions encountered during the site work, and on the results of

laboratory and field tests performed during the investigation. There may however

be conditions at or adjacent to the site which have not been taken into account,

such as unpredictable soil strata and water conditions between or below

exploratory holes. A careful watch should be maintained during any future

groundworks and the comments of this report reviewed as necessary.

This report has been prepared for Oxfordshire County Council. This report shall

not be relied upon or transferred to other parties without the written consent of

CC Ground Investigations Ltd. Should any information contained within this

report be used by any unauthorised third party it is done so at their own risk and

shall not be the responsibility of CC Ground Investigations Ltd.

2. SITE DESCRIPTION AND GEOLOGY

2.1 Site Description

The area of investigation follows the proposed route of a new all purpose

carriageway across areas of existing agricultural fields with some locations accessed

from existing carriageways, near Harwell, Oxfordshire. The site is centred on the

approximate National Grid Reference SU 501 889.

2.2 Geology

Geological Records (British Geological Survey (BGS), England and Wales sheet 253

Abingdon 1:50,000 scale) indicate the site is underlain by superficial head deposits.

The solid geology comprises the West Melbury Marly Chalk Formation and the

Upper Greensands Formation was recorded.

3. GROUND INVESTIGATION

3.1 Fieldwork

Twenty three exploratory holes were carried out between the 11th and the 26th of

August 2014. All exploratory hole locations are shown on the site plan (Appendix

A). The exploratory hole locations were set out by CCGI as directed by the Client on

site.

The fieldwork was carried out in general accordance with BS5930, Amendment 2

(2010).

The boreholes, referenced BH03 to BH07, BH08A and BH09 (Exploratory Hole Data

– Appendix B) were formed using a track mounted Comacchio MC300 or Fraste ML

multi purpose rig. Following CAT scanning, hand tools were used to excavate an

inspection pit to a maximum depth of 1.20m to check for buried services. Bulk and

environmental samples were taken and retained from the inspection pits. The

boreholes were then advanced using percussive sampling techniques to produce

continuous disturbed samples of 98mm diameter.

On refusal of percussive sampling the boreholes were continued by rotary core

drilling techniques utilising a water flush. A double‐tube swivel core barrel with a

semi‐rigid plastic liner was utilised to recover continuous cores of 91mm diameter.

Soil and rock samples were retained in semi‐rigid plastic liners, which were capped

on site to prevent moisture loss.


Page 4

No groundwater was encountered in the boreholes prior to the use of water flush.

On completion gas/water monitoring standpipes were installed in BH07 and BH09.

Each installation consisted of a 50mm ID HDPE slotted tube set in a filter response

zone of limestone free gravel. The installation was sealed above with a bentonite

pellet seal and accessed via a valve assembly. The installations were protected at

the surface by a lockable, galvanised steel borehole helmet set in concrete.

Installation details are given on the relevant borehole log.

On completion, BH03, BH04, BH05, BH06 and BH08A were backfilled with arisings

and bentonite pellets and the surface reinstated.

The inspection pits, referenced BH01A, BH01B, BH02A, BH02B and BH08A,

(Exploratory Hole Data – Appendix B) were excavated using hand digging tools.

Representative bulk disturbed samples and environmental samples were taken and

retained in sealed plastic bags and airtight containers to retain moisture content.

All inspection pits refused hand excavation at shallow depth. Appropriate

comments are made on the relevant logs.

Following CAT scanning, the trial pits, referenced TP01 to TP09, (Exploratory Hole

Data – Appendix B) were excavated by a JCB 3CX mechanical excavator with a

0.60m wide backactor bucket. Initially the trial pits were excavated by hand to

check for the presence of buried services.

On completion all trial pits were backfilled with arisings. The ground surface was

reinstated and left slightly mounded to accommodate future settlement.


Page 5

Subsequent to fieldwork, all exploratory hole positions were surveyed and National

Grid co‐ordinates and levels are presented on the relevant log.

On completion of fieldwork all samples were brought to CCGI’s office for storage.

3.2 In Situ Testing

Standard penetration tests (SPT) were carried out in general accordance with BS EN

ISO 22476‐3:2005. A split barrel or a solid cone was used depending upon the

materials encountered and the split barrel samples retained as small disturbed

samples. The SPT N value was taken as the number of blows to penetrate the

300mm test drive following a 150mm seating drive. Where low penetration was

recorded the seating drive was terminated at 25 blows and the test drive

completed after a further 50 blows. SPT results are summarised as uncorrected N

values on the borehole logs. SPT hammer calibration data is presented in Appendix

F.

3.3 Logging

Soil and rock samples from the exploratory holes were logged by an Engineering

Geologist in general accordance with BS5930, Amendment 2 (2010). Bulk, small

disturbed, core and environmental soil samples were obtained at a range of depths.

Samples were stored on site in temperature controlled conditions. Soil and rock

descriptions are presented in the borehole logs together with details of sampling, in

situ testing and relevant comments on drilling techniques.

3.4 Laboratory Testing

The following laboratory tests were carried out by Professional Soils Laboratory

(UKAS No. 4043) in accordance with BS1377:1990, Parts 1 to 8, unless otherwise

stated. The results are presented in Appendix D.

Soil Analysis NotesInorganic soil analysis was carried out on a dried sample, crushed to pass a 425µm sieve, in accordance with BS1377.

Organic soil analysis was carried out on an 'as received' sample. Organics results are corrected for moisture and expressed on a dry weight basis.

The Loss on Drying, used to express organics analysis on an air dried basis, is carried out at a temperature of 28°C +/‐2°C.

DisposalFrom the issue date of this test certificate, samples will be held for the following times prior to disposal :‐

Soils ‐ 1 month, Liquids ‐ 2 weeks, Asbestos (test portion) ‐ 6 months

Key: P‐Plas c T‐Tub

DETS cannot be held responsible for the integrity of samples received whereby the laboratory did not undertake the sampling. In this instance samples received may

be deviating. Deviating Sample criteria are based on British and International standards and laboratory trials in conjunction with the UKAS note 'Guidance on

Deviating Samples'. All samples received are listed above. However, those samples that have additional comments in relation to hold time and/or inappropriate

containers are deviating due to the reasons stated. This means that the analysis is accredited where applicable, but results may be compromised due to sample

deviations. If no sampled date (soils) or date+time (waters) has been supplied then samples are deviating. However, if you are able to supply a sampled date (and

time for waters) this will prevent samples being reported as deviating where specific hold times are not exceeded and where the container supplied is suitable.
