Pipeline & Overhead Line (OHL) Surveys

Pipeline and Overhead Line (OHL) Surveys are vital components of topographic and infrastructure development projects. These surveys help in planning, constructing, and maintaining utility corridors such as water pipelines, gas lines, power transmission routes, and telecommunication lines. Accurate spatial data collection ensures compliance with regulatory standards and helps avoid costly design errors or ground conflicts.

Key Features & Benefits:

1. Route Alignment & Corridor Mapping
  • Detailed alignment planning using GPS, total stations, and UAVs for optimal route selection.
  • Identifies environmental constraints and terrain challenges along the route.
2. Pipeline Profile & Longitudinal Sections
  • Precise topographic profiles for designing slopes, bends, and trench depths.
  • Assists in hydraulic and structural design of buried pipelines.
3. OHL Tower Positioning & Clearance Analysis
  • Surveys tower positions, sag profiles, and conductor clearance from ground, roads, and obstacles.
  • Ensures compliance with transmission line safety and clearance standards.
4. Integration with GIS & CAD
  • Generates output compatible with AutoCAD Civil 3D, GIS platforms, and BIM models.
  • Enables long-term asset management and route maintenance planning.
5. UAV & LiDAR-Based Surveying
  • Rapid terrain capture in inaccessible or high-risk zones using drones and LiDAR.
  • Produces high-resolution 3D point clouds and orthophotos for route visualization.
6. Utility Conflict Detection & Permitting
  • Identifies underground and overhead utility conflicts before construction begins.
  • Supports documentation for regulatory approvals and right-of-way (ROW) permits.
