1.10. Abandoned Borings

No measurement or payment shall be made for borings abandoned or lost before reaching the specified depths except as otherwise provided hereinafter for false start or unless and to the extent the S.O deems that the borings so abandoned are acceptable. Except with the specific permission of the S.O the Contractor shall not abandon or complete any boring or remove any casing or drilling equipment without first allowing the S.O the opportunity to obtain the position and depth of the boring prior to abandonment or completion and any other information which the S.O may require. No allowance or payment whatsoever will be made for any boring abandoned or completed without compliance with these stipulations. In addition in order to receive consideration for payment for abandoned boring the Contractor shall furnish the S.O with complete records and samples for the depths penetration in the same manner as that prescribed for completed borings.

1.11 Boring False Start

It is intended that the borings shall be made so as to clear all underground pipes, cables, conduits and other underground utilities or structures. However should the Contractor be unable to complete any boring due to encountering utilities or structures which cannot be reasonably foreseen after Clause 1.12 of this Specified has been complied with or because other obstructions are encountered which the S.O considered are of unusual nature and that failure to penetrate the obstruction is not the fault of the Contractor’s method or equipment a false start will be allowed form the ground surface to the lowest elevation penetrated will be paid at the rate indicated in the Scope of Works for the particular type of sampler used and boring being performed, provided however that the Contractor shall submit to the S.O a complete record of all false starts.

3.0 SAMPLING

3.1 Continuous Sampling and Disturbed Samples

Continuous samples are to be taken when indicated on the drawings and Scope of Works or when directed by the S.O. When continuous samples are required they shall be taken to a depth of 5 m measured from the existing ground or bed level of water channel or body by the S.O.

Unless otherwise specified continuous samples may be regarded as “disturbed”

samples. When continuous samples are not required disturbed samples using ordinary drive split barrel samplers shall be taken at intervals not exceeding 1.5 m and at any point where there is a change in material type.

The procedure for obtaining split barrel samples shall be as directed in Test 1.9- B.S 1377:1975. The taking of disturbed samples shall be concurrent with the Standard Penetration Test unless directed otherwise by the S.O. The requirements for the Standard Penetration Test is described in Clause 5.1 of this Specification.

The minimum amount of soil sample to be collected shall be based on meeting the requirement necessary for the various classification tests, such as Moisture content Atterberg Limits and Particle Size Distribution.

When sufficient quantity of soil is not obtained in the first instance the sampling operation shall be repeated at no extra cost. It is the Contractor’s responsibility to choose an appropriate sampler to an appropriate sampler to ensure that a sufficient quantity of material is obtained in the least number of sampling operations. However when the operation has been repeated for a total of 3 times and sampler with a flap retainer or other sample retaining device has been used at least once the operation need not be continued. The Contractor will only be paid for unsuccessful sampling if the S.O is satisfied that the above procedure has been complied.

E/9

(28)

3.0 Undisturbed Samples 3.2.1 General

Undisturbed samples shall be taken when cohesive soil is encountered in the boring. If there is no change in the soil type undisturbed samples shall be taken at 1.5 m intervals. Where the depths of undisturbed sampling are indicated in Contract Drawings these depths are to be deemed as provisional and the quantity of undisturbed samples to be taken may vary according to the actual site condition. It is understood that such variations should not affect the rates quoted by the Contractor in the Scope of Works.

Hydraulic force shall be used to drive the sampling tube and the drilling machines used must be weighted sufficiently to exert a force of up to 25kN without uplift of the drilling machine. If a satisfactory undisturbed sample cannot be obtained with the above force a 63.5 mm O.D split tube drive sampler with liner shall be used a deflected per clean out auger with water or drilling mud circulation shall be used to clean out the bottom of the holes or casing prior to sampling. After the described elevation is reached the circulation shaft be stopped and the auger shall be rotated to bail out any gravel accumulated at the bottom of the hole.

When sampling below the water table or where water has been used to clean the casing measured, noted and the recovery ratio shall be computed as the recovery length divided by the length of the sample stroke. Undisturbed samples with recovery rations less than 60% will not be accepted. In such cases the hole shall be cleaned out and a standard split barrel sample shall be taken (disturbed sample)

The Contractor will only be paid for unsuccessful sampling of the S.O is satisfied that the Contractor shall complied with the procedure in obtaining the sample.

3.2.2 Cohesive Samples

For soils having some cohesion the thin walled tube of minimum 50 mm (2 in) outside diameter as described in ASTM.D.587 – 74 shall be used to obtain undisturbed samples. The method of sampling shall also follow that standard.

3.2.3 Cohesion less Sample
