GeneralSoils were prepared in accordance with BS1377:Part 1:1990 Section 7

Laboratory soil sample descriptions in general accordance with BS5930:1999

Where samples are not tested on same date for a particular test type, Test Date quoted refers

to the day of testing of final sample

All samples will be disposed of within 1 month of presentation of this report unless otherwise advised

Natural Moisture ContentTested in accordance to BS1377:Part 2:1990 Section 3.2

A sample quantity of 100g is used for fine-grained soils, where available

Where sample quantity is critical, a minimum of 50g may be used, in accordance with BS1377:Part 2:1990

A sample quantity of 300g to 350g is used for medium-grained soils, 3kg is used for coarse-grained soils.

Atterberg LimitsTested in accordance to BS1377:Part 2:1990; Section 4.4 for the Liquid Limit, Section 5 for the

determination of the Plastic Limit and Plasticity Index

Suction Tests Test Date: (Q)*Suction Test carried out in accordance to the accredited In-house Procedure MTLB001 with reference to

the BRE paper IP4/93 (Corrected) 'A Method of Determining the State of Desiccation in Clay Soils'

(Unless otherwise stated the filter paper moisture content was determined after 5 to 10 days contact and

the test was prepared from a remoulded disturbed sample in accordance with in-house procedures)

* Where denoted by '(Q)' following Test Date above, the test has been performed using 2 soil discs and quartered filter papers.

The filter paper tests are conducted in a controlled environment within a temperature range of 16oC to 24oC.

Average Suction values (in kPa) calculated using the BRE paper IP4/93 calibration are quoted with the maximum and

minimum suction obtained, as indicated by error bars either side of plotted point.

Where possible, suction values should be compared with remote borehole values, to determine relative desiccation.

Each new batch of filter papers used for testing is checked for its consistency against the standard BRE calibration curve

using a pressure membrane extractor. The current filter paper batch, J113976969, shows good consistency against the BRE curve,

more information is available upon request. Studies on In-house calibrations using a pressure membrane extractor continue.
