Sunbury Train Line Powerline Survey
July 7, 2021

Balpara was engaged by the Rail Infrastructure Alliance to complete a review of proposed design clearances as part of the Sunbury train line upgrade. This was to ensure the Rail Overhead Line Equipment (OHLE) cables and structures achieved statutory clearances to the powerlines crossing the rail corridor at every location necessary for the extent of the train line in Jemena’s Network region. 

 

Using power distribution survey and design techniques, Balpara verified the clearances at all Jemena overhead powerlines using electrical distribution industry design calculations and software. These checks ensured all clearances meet power utility standards for safety. 

 

Project Overview

 

The $2.1 billion Sunbury Line Upgrade will see a combination of power upgrades and platform extensions to support High-Capacity Metro Trains travelling through the Metro Tunnel. 

 

Project Scope

 

  • Completing a full survey of existing power poles and conductors to allow for a comprehensive review. 
  • Surveying several consecutive spans of conductor for the design software/standards used in the power industry to be calculated correctly. 
  • Creating a full design and clearance report provided on the existing overhead powerlines verifying the clearances, including  calculated height of the conductors over the existing rail tracks. 


Value Add

 

We were able to verify that all clearances were met.   

 

Relevant Accreditation/Quality Standards

 

  • Balpara has held ISO9001 certification for over six years without non-conformances and attained re-certification to the new AS/NZS 2016 Standard. AusNet accredited surveying, design and drafting.

Balpara was engaged by civil constructor, Directbor, to provide detailing and drafting services to connect the Kerang Solar Plant to the nearby Kerang Terminal Station. Project Overview The Kerang Solar Plant in Victoria is a BSR Energy project, which aims to generate enough clean and reliable energy to offset the annual consumption of approximately 16,000 homes, contributing to a more sustainable future while reducing reliance on traditional power sources. Construction commenced in March 2024, and is projected to save 66,380 tonnes of CO2-equivalent emissions annually. The land parcel is over 64 hectares in size, with the plan to visually integrate into the surrounding agricultural landscape with extensive planting of native flora around the entire project perimeter. The bell-mouth intersection off Lodden Valley Highway will be upgraded for improved accessibility and safety as part of this project. Scope Balpara’s involvement in the project was undertaken over the course of a month starting in August 2024, with Directbor engaging the team on behalf of Powercor. The Balpara team completed detailing and drafting of assets connecting the new Kerang Solar Plant to Powercor’s distribution network. Balpara employed GPS technology to accurately capture underground asset locations and create a comprehensive plan of assets within the short timeframe required. The project scope included: Capturing new underground asset locations to required standard using GPS equipment. Creating as-built plans of relevant assets to current Powercor standards. Providing captured 3D data to Powercor for future asset relocations. Value Add Balpara provided timely and accurate drawings and was able to quickly meet the needs of client variations. The Balpara team is well versed in working with all utility standards, including Powercor, which helped to streamline the project. Accreditations Powercor Standards
