10 contracts listed · 29,152 m of trenchless drilling
| Name of contract | Project description | Trenchless drilling | Location |
|---|---|---|---|
| Modification & Energization of 11kV & 33kV Overhead Line Crossing to Underground Cable | Executed large-scale trenchless underground conversion of live 11kV and 33kV railway power crossings through micro-tunnelling and HDD methods. The scope included precision bore installations beneath railway tracks and roads, followed by integration with overhead networks, XLPE terminations, and protection systems to ensure compliant railway-grade energization. | 2,370 m | Bhojudih, Asansol, Bankura – WB |
| Adra PLC Underground Conversion (Phase-D) | Delivered Horizontal Directional Drilling based undergrounding of 11kV power line crossings using HDPE casing pipes up to 250 mm diameter under active railway corridors. The project involved structural pole modifications and electrical interface works post-trenchless installation, ensuring safe energization under railway authority coordination. | 4,050 m | Mahuda, Bhaga, Dhanbad – JH |
| Conversion of 11kV Overhead Crossings – Chakradharpur Division | Executed extensive micro-drilled and HDD trenchless construction to replace overhead 11kV railway power lines with underground cable systems. Electrical integration included HT terminations, jointing, gantry modifications, and earthing compliant with railway standards. | 2,700 m | Adityapur, Chaibasa, Tata – JH |
| 33kV Undergrounding Against Infringement – Bondamunda Yard | Implemented high-capacity HDD and micro-drilled trenchless crossings for 33kV cable infrastructure within operational railway yards. The project focused on underground corridor creation, followed by XLPE terminations, gantry integration, and fault diagnostic support systems. | 3,560 m | Rourkela – OD |
| Conversion of Railway-Owned 33kV Crossings – CKP Division | Delivered HDD-based underground conversion of 33kV overhead power lines across railway track crossings. The trenchless scope included casing installation, and structural works for safe overground transition. | 1,800 m | Kendujhar, Rourkela – OD / Jamshedpur – JH |
| 33kV Sectional Isolation & Tunnel Electrification – CKP Division | Executed trenchless crossings and underground cable routing for 33kV sectional isolation across multiple railway locations. The work included long-distance directional drilling under sensitive terrain, followed by HT/LT power distribution integration and substation interface works. | 3,400 m | Singbhum, JH |
| Coastal Belt Underground Conversion – Srikakulam (Waltair Division) | Delivered coastal HDD trenchless installations replacing overhead railway distribution lines with underground systems. The work included long-distance directional drilling under sensitive coastal terrain, followed by HT/LT power distribution integration and substation interface works. | 622 m | Srikakulam, AP |
| Coastal Belt Underground Conversion – Vizianagaram (Waltair Division) | Executed trenchless HDD crossings for conversion of overhead lines to underground cable networks in coastal railway zones. The project emphasized bore stability, underground corridor engineering, and high-capacity feeder integration post-installation. | 1,450 m | Vizianagram, AP |
| GVS Projects Private Limited | HDD and trenchless installations for various kinds of pipes and utility installations. | 8,000 m | Vishakhapatnam, AP |
| Sainik Mining & Allied Services Limited | Undergrounding of NTPC's 33kV overhead power lines to enable mining operations. | 1,200 m | Talcher, Odisha |
