Preparation of Geological Face logs & Cross passages of tunnel with RESS (Required Excavation & Support System). • 3D Geological Map (Main Tunnel & Escape Tunnel), 2D Geological Cross section- Vertical longitudinal profile along the center line of the tunnel. • Overbreak report in underground excavations with proper documentation. • Rock Mass Classification as per NATM/ONORM specification in relation to Ground type and Behavior type. • Probe holes to know the geology ahead of the tunnel face. • MPBX (Multi-Point Borehole Extensometers), Load cell and Bi-reflex targets installation are extensively used for the measurement of deformation During Tunneling and During sub way construction. • Preparation of Drilling Pattern using iSURE (Software Provided by Sandvik 922i and Dt 820). • To change the design and drawing of tunnel as per the actual site condition consultation • To calculate the Rock mass Rating (RMR) and Interpret Rock Class. • Treatment and rock mass support using Shotcrete, Rock Bolting, Lattice girders, Steel ribs, Fore poling etc. • Seismic Vibration monitoring during blasting and optimizing Overbreak control.

AutoCAD & Drill Plan iSURE®: Intelligent Sandvik Underground Excavation Software.  Basic knowledge of Slide and Dips Software.
