GEOTECHNICAL INVESTIGATION (SUBSURFACE) FOR WARDHA PROJECT

Mobilization of necessary plant, equipment, Men and materials for the complete geo-technical investigation work as per specifications, drawings and instructions of the Engineer and to complete the same within the stipulated time schedule and demobilization (Rotary Calyx)

Making suitable arrangement for offshore drilling with boring platform / fishing trawlers / boats /positioning platform with anchor at borehole Location in river/ water body with maximum depth of water is about 8m (including Shifting of boring platform from one BH locations to another BH location in water points)

Making 150mm nominal diameter bore holes at various locations in all types of soils with suitable approved method of boring, performing Standard Penetration Tests (As per IS:2131) at every 1.5m intervals and collecting UDS in cohesive soil (Depth from 0m water level to river bed bottom) Drilling in Off Shore Locations: Drilling in Soil

Making 150mm nominal diameter bore holes at various locations in all types of soils with suitable approved method of boring, performing Standard Penetration Tests (As per IS:2131) at every 1.5m intervals and collecting UDS in cohesive soil (Depth from 0m water level to river bed bottom) Drilling in Off Shore Locations: Drilling in SDR/ Soft Rock using NX Tungsten carbide bit including collection of rock care samples, logging and submitting the same to client.
