Waratah Place Zone Substation Project
July 20, 2019

 

Balpara was engaged by Daly’s Constructions Australia to devise an electrical design and as-built detailing for the installation of 66kV circuits at the new Waratah Place Zone substation.

 

Project Overview

Balpara's electrical engineering team was enlisted by Daly’s to devise an electrical design, including as-built detailing, for the installation of 66kV circuits at the new Waratah Place Zone substation in Melbourne’s CBD. The new zone substation forms a major part of the Metro and CBD Security of Supply project, the purpose of which is to meet increased demand from residential and commercial growth in the CBD, as well to improve the reliability of the supply across the city.

 

In accordance with CitiPower, Daly’s and local manufacturer standards, we devised a design which mapped the best route for the installation of the 66kV circuits, in addition to marking out joint bay locations in the CBD.

 

Following the demolition of the previous zone substation ‘W’, new foundational structures were constructed, upon which a new zone substation has been built. The next and final phase of the project is the installation of new electrical infrastructure, including 10 x 66kV circuits, at the Waratah Place Zone substation.

 

By overlaying the 3D model with the 3D point cloud (see image above), we identified that previously designed ventilation ducts would not meet utility clearance standards. This finding ultimately saved the project significant construction and materials costs.

Project Scope

  • Preparation of route for 66kV cabling to cable specification
  • Creating electrical detailing and as-built drawings in line with applicable standards
  • Checking of civil base plan for water, gas and sewerage
  • Preparation of electrical as-built drawings once installation is complete
  • Design of electrical cable support structures within basement
  • 3D Scanning of basement to verify design tolerances
  • Flagging of any clashes within basement before electrical cables are installed
  • Electrical design of a new Duresca 66kV insulated bus bar for manufacturing by MGC (Switzerland)

Balpara has held ISO9001 certification since March 2011 without non-conformances and attained re-certification to the new AS/NZS 2016 standard.

Lathams Road Carrum Downs Upgrade

June 30, 2025
Balpara was contracted to carry out detailing and auditing services for the Lathams Road Upgrades in Carrum Downs, as part of Victoria’s Big Build. Project Overview This project involved multiple upgrades across a 2.5km section of Lathams Road. The upgrade included the addition of additional lanes going both ways, upgrading 13 intersections along the road, building a new bridge over the Peninsula Link, adding walking and cycling paths, widening existing roundabouts, and installing safety barriers. The project had a strong emphasis on community consideration and utilising sustainable project materials. As an example, drainage pipes and kerbs installed used recycled plastic and a social procurement strategy was formulated by the developer, Winslow, to actively engage Indigenous businesses, generating meaningful employment and promoting indigenous representation in the construction industry. These upgrades were completed with the intention of improving traffic flow and travel times, enhancing safety for pedestrians and cyclists and boosting the connectivity of local businesses in the Carrum Downs and Seaford community. Lathams Road is a vital road link for many of those in the surrounding community, and as such, these upgrades substantially improve traffic flow and access to surrounding industrial areas. Scope The team at Balpara was engaged to carry out detailing and auditing services for this road upgrade, including detailing, drafting and auditing. Detailing of the assets according to United Energy Standards: Public lighting poles Back of kerbs, both existing and new Conduits Finish surface levels Boundary lines Fences Other services in trench, i.e. storm water, comms, gas and more Drafting as-builts Auditing: Conduit installation to design Checking depths / offsets of conduits for compliance Maintaining compliant separation to other assets in the ground Checking backfills and warning tape compliance Checking cables sizes and type being installed Checking connections inside poles and pits Checking correct poles and lanterns, and pole numbers are being installed Producing audit reports for clients Value Add Balpara specialises in detailing and auditing and have a large team dedicated to all utilities across Victoria.
