Amount

Exploratory drilling of Boreholes down to required depth (upto 40m), drilling of 150mm diameter boreholes in all type of soils except hard rock and large boulders (boulder core more than 30 cm), including refilling and reinstating surface, and disposing off surplus material by using appropriate/suitable drilling machine capable for advancing through occasional seams of hard strata to be employed, where necessary in Dry area

Exploratory drilling of Boreholes down to required depth (upto 40m),, drilling of 150mm diameter boreholes in all type of soils except hard rock and large boulders (boulder core more than 30 cm), including refilling and reinstating surface, and disposing off surplus material by using appropriate/suitable drilling machine capable for advancing through occasional seams of hard strata to be employed where necessary in River bed area including standing/flowing water up to 2 M depth with all necessary arrangements.

Drilling of NX size borehole (75 mm dia) in all types of hard rock (fresh rock) up to 40m depth by using appropriate/suitable drilling machine capable to drill through hard rock comprising Quartzo-feldspathic granitic rock and collection of rock core samples from boreholes and preserving in boxes.

Conducting standard penetration Test - The standard penetration test shall be conducted in all bore holes at specified interval as per the general specification suggested by IS code of practice. SPT shall be terminated on recording 100 blows per 30cm or less penetration. The disturbed samples obtained from the split spoon sampler shall be visually classified, labeled for identification and preserved for laboratory testing.

Collecting undisturbed soil samples- Taking out undisturbed samples of soil from bore holes, including provision of air tight containers for packing and, labelling incl. transporting the samples to laboratory. Piston sampler shall be used for extracting undisturbed samples where necessary. Samples shall be collected as per IS 2720.

Collecting disturbed soil samples- Taking out 100mm dia & 450mm long disturbed samples of soil from bore holes, including provision of air tight containers for packing, labelling and transporting the samples to laboratory. Samples shall be collected as per IS 2720.

Collection of water samples. - Collection of water samples as per IS codes.

In-situ permeability test in bore hole at Tunnel sites as per IS 5529 (part – II for rock)
