Our Capabilities

Engineering Built on Modern Technology

From mechanized tunneling rigs to BIM-driven design, every project is delivered with equipment, instrumentation and software chosen for Nepal’s most demanding terrain.

Home/Technology
Mechanized Tunneling

Equipment Built for Complex Excavation

Our underground works are delivered with modern mechanized fleets — cutting cycle times, improving safety, and giving us a reliable production rate even in young rock conditions.

Drilling Jumbos

Multi-boom hydraulic drill rigs for precise blast-hole patterns and faster excavation cycles in headrace and access tunnels.

  • 2 & 3-boom configurations
  • Computer-aided drilling plans
  • Up to 64 mm hole diameter

Loaders & Haulers

Low-profile underground loaders and dump trucks sized for tunnel cross-sections, keeping mucking cycles fast and safe.

  • LHDs sized 3-10 m³ bucket
  • Tier-compliant emissions
  • Operator camera + lighting

Shotcrete & Support Systems

Robotic shotcrete spraying for accurate support thickness, paired with rockbolting and steel-rib systems for primary support.

  • Robotic spraying booms
  • Wet-mix high-output pumps
  • Rockbolt rigs & rib erectors
Survey & Monitoring

Precision Instruments for Field Decisions

We deploy modern survey, instrumentation and remote-sensing technology so that engineering decisions on site are made against accurate, real-time data — whether that’s tunnel convergence, slope stability, or transmission line alignment.

The combination of total stations, dual-frequency GNSS, drone photogrammetry and geotechnical instrumentation forms our standard project monitoring stack.

  • Robotic Total Stations Sub-millimetre setting out, automated convergence monitoring on critical tunnel sections.
  • Dual-frequency GNSS Centimetre-level positioning for headworks layout, transmission corridors and earthwork control.
  • Drone Photogrammetry & LiDAR High-resolution terrain models, volume calculations and progress monitoring for earthworks.
  • Geotechnical Instrumentation Inclinometers, piezometers and load cells monitored continuously where slope or load behaviour matters.

Real-time monitoring, on the rig and at HQ.

Field-captured data flows from instruments to dashboards within minutes — so site engineers and the head office work from the same numbers.

Software & Project Management

Industry-Standard Tools, End to End

Design, scheduling and field execution are tied together with software our engineers and project managers know cold.

AutoCAD & Civil 3D

Design and detailing for civil works, drainage, road alignments and powerhouse buildings — with shared drawing standards across the engineering team.

  • 2D & 3D design workflows
  • Corridor & alignment modeling
  • Surface & earthwork analysis

Primavera P6

Master scheduling and progress tracking for every project — client-facing earned value reporting, critical path management and resource leveling.

  • Baseline + actuals tracking
  • Earned-value reporting
  • Resource & cost loading

BIM & Coordination

3D coordination of civil, mechanical and electrical works on EPC projects — reducing clashes and rework before they reach the site.

  • Federated model reviews
  • Clash detection workflows
  • Quantity take-off from model
