The Contractor shall submit such recommendations recommendations to the t he Client. Should the Client agree, the scope shall be altered accordingly accordingly and price agreed, prior to the commencement of the revised scope. Particular emphasis shall be placed by the Contractor on: •

The required minimum diameter may be undershot with approval by the Client. Water flushing may not be used for drilling in soil and weathered rock in order to preserve the natural moisture content and the sample quality. If massive rock or huge boulders are encountered the use of water flushing is allowed. Drilling rig, drilling method and drilling diameter have to be chosen in a way that all requirements specified in this document and the standards are guaranteed. All boreholes have to be backfilled immediately after all drilling works and in-situ testing is completed. Backfill works have to be carried out carefully to avoid settlements. The backfill material shall be adequate soil material available in the vicinity of the site. The Contractor is responsible for the provision and transport of the material. As an option, some boreholes may require backfill using cement based grout or Bentonite pellets (Compactonit). The Contractor is responsible for the provision and transport of the material. Due to the amount of drillings, Contractor shall be ready to employ more than one o ne drill rig for simultaneous simultaneous drilling.

The initial and final groundwater elevation, if significantly different, as well as any additional groundwater horizons identified shall be presented in the borehole logs. 6.2.5

Sampling Sampling of soil, rock and water shall be carried out according to ASTM D213 and ASTM D4220. Contractor has to make sure that sufficient soil sampling material is taken from trial pits and boreholes to carry out all laboratory laboratory tests specified in this document according according to the t he applicable standards. Size of samples shall be large enough so that retain samples will be still available after completion of laboratory testing. In case cohesive soils will be encountered special emphasis shall be placed on taking undisturbed samples which are necessary for soil mechanical tests such as triaxial tests

Groundwater Samples Samples of groundwater shall be taken if groundwater is encountered within the boreholes. Samples from boreholes shall be taken after the th e groundwater has been cleared by pumping to avoid a negative influence from drilling works. Water samples shall be filled into clean containers that shall be provided by the analysing laboratory. Inappropriate sample containers will be rejected.

6.2.8

Logging Logs of drillings have to be made according to ASTM D5434.

Each photo (minimum camera resolution 6 megapixel – photos in best quality) shall include a label indicating the title of the drilling and sample, a scale, a colour bar, and depth of the sample at each side of the core box. The photos shall be taken vertically down on the samples to avoid distortion. The light conditions shall be carefully chosen to avoid over- / underexposure or shadow. The photos shall be submitted in hard copy and digital format (.jpg) on CD. Photos of poor quality will not be accepted.


ILF-SPC-AOT-CI-002-B 25. 10. 2013

The boreholes produced by the screw shall be backfilled immediately after performance of the tests. For backfilling, the natural soil furthered furthered by the screw shall be used. The tests shall be carried out according to American Standard STP 38477S 6.2.13
