Over Head Power Transmission Line Survey

Overhead Power Transmission Line Survey

Vertex Inspection & Survey (Pvt.) Ltd. provides comprehensive route surveys for overhead power transmission line projects, delivering precise geospatial data for tower positioning, corridor mapping, and clearance analysis essential for reliable power transmission infrastructure.

Transmission Line Survey Scope

Overhead power transmission lines traverse diverse terrain and require detailed survey data for route selection, tower placement, conductor sag analysis, and right-of-way management. Our survey teams are experienced in the specialized requirements of power transmission projects.

Our Survey Services

• Route Survey: Detailed corridor mapping including terrain, obstacles, crossings, and access requirements.
• Tower Positioning: Precise GPS coordinates for each tower location based on span lengths and terrain.
• Cross-Section Survey: Tower cross-section profiles for conductor clearance and vegetation management.
• Right-of-Way Mapping: Corridor boundaries, affected properties, and compensation area identification.
• Crossing Surveys: Detailed surveys at road, river, railway, and existing utility crossings.
• Clearance Analysis: Vertical and horizontal clearance verification for conductor safety requirements.

Technology & Equipment

We employ differential GPS for high-accuracy tower positioning, total stations for detailed cross-section measurements, and drone technology for rapid corridor mapping over long distances. All data is processed using specialized power line design software.

Survey Deliverables

• Tower location maps with georeferenced coordinates
• Corridor cross-section profiles at regular intervals
• Right-of-way boundary maps
• Crossing detail drawings for road and river crossings
• Vegetation clearance zone maps
• As-built documentation for completed transmission lines

Applications

Our transmission line surveys serve 132kV, 230kV, 400kV, and 765kV power transmission projects, providing the accurate geospatial foundation for safe and efficient power transmission infrastructure development across Bangladesh.
