Sag and sway

Overhead asset experts

As a leading service provider to electrical utilities companies, Balpara specialises in providing sag and sway analysis and establishing no-go zones for overhead assets. Sag and sway need to be considered if power assets are within close proximity to built infrastructure or future construction sites.
A sag and sway analysis can be required in order to obtain a Permit to Work.


Balpara has experience and expertise analysing sag and sway across various projects and sectors, including infrastructure, utilities, councils, transport and urban developments, as well as devising compliant OH designs if assets require relocating. We are a chosen provider of Electrical Infrastructure Worksite Inspections for AusNet Services, as well as a trusted partner of utilities such as CitiPower/Powercor, Jemena and United Energy.
