What we deliver

A total service,
start to finish

From initial feasibility planning and line route selection through to survey, design and construction management — Wedcon covers every stage of your transmission or distribution project.

Feasibility  →  Route selection  →  Survey  →  Design  →  Construction management

Planning & feasibility

We start before the design does

Before a line is designed, it needs to be justified, routed and scoped. We provide the full upfront planning service to get your project on solid footing.

Feasibility studies
Technical and economic feasibility assessment for new line projects and augmentations.
Budget estimates
Detailed cost estimates to support project approval and capital planning processes.
Route selection
New line routing and relocation of existing lines, balancing engineering, environment and cost.
Property acquisition
Identification of easement and property acquisition requirements for new line corridors.
Line design & survey

Transmission line design up to 330kV

Full overhead line design using industry-leading PLS software, supported by precision RTK GPS surveying.

Layout design — PLS-CADD
Structure spotting and layout design for sub-transmission and transmission lines up to 330kV.
Structural analysis — PLS-POLE & TOWER
Design analysis and checking of pole and lattice tower structures.
Route surveying — RTK GPS
Precise line route surveying and set-out using real-time kinematic GPS systems.
Steel fabrication drawings
Production of workshop-ready steel fabrication drawings for custom structure components.
Feeder rating investigation
Conductor catenary survey, thermal rating analysis and detailed reporting.
