Project Spotlight — 500 kV Line Clearance Remediation
Client: BC Hydro, British Columbia, Canada
Status: Completed, 2017–2019
Clearance violations on a 500 kV lattice-tower transmission line have no easy fix.
The line is a backbone asset, extended outages are unacceptable, and any correction must be engineered against the full structural reality of towers that have stood for decades.
TAWARA Group assessed each affected span and built PLS-Tower models of the structures involved, so every remediation option, raising existing structures, re-tensioning conductors, rested on detailed structural analysis rather than assumption.
The deliverable was a full construction package, with each viable option checked against safety and regulatory requirements.
Services applied: Clearance analysis. Structural assessment. PLS-Tower modelling. Remediation design.
Model it, prove it, then build it.
Now accepting new projects.
