HV Tower works

The relocation of high voltage (HV) transmission lines away from Childers Street is nearing completion.

All permanent transmission towers are now in place and the temporary and existing towers have been removed from Childers Street.

These towers need to be permanently relocated to make way for the construction and operation of the western tunnel entrance.

Overview

Works to string new HV transmission lines and restring (transfer) existing HV transmission lines between towers has commenced and will occur in two stages:

  • Ongoing stringing new transmission lines between permanent tower 33 on Hobsons Road and permanent tower 34, and from permanent tower 34 to permanent tower 35.
  • Safely restringing the existing transmission lines from the temporary towers along Childers Street to permanent tower 33 and permanent tower 34.

Works in August include the installation of required maintenance access and safety measurements around the tower sites, as well as the final transmission line transfer within the industrial land south of the rail corridor.

Rail freight yard works

Works to finalise the relocation of the HV transmission towers will be undertaken within, and south of, the rail corridor. This will involve night works, and short-term traffic management on Dynon Road and Lloyd Street to facilitate access to the tower sites within the industrial area south of the rail corridor.

Construction of retaining wall

A retaining wall, which will serve as a maintenance platform for permanent tower 34, will be constructed adjacent to the tower site.

What to be aware of

  • Due to the close proximity of the retaining wall to the rail corridor, some of these works need to take place at night when trains aren’t running
  • Earthworks to create a level platform for equipment to build the retaining wall will be undertaken using an excavator and bob cat. This activity is expected to generate low to medium levels of noise
  • Works to build the retaining wall will be undertaken using cranes and trucks with squawker reversing beepers. These works are expected to generate low to medium levels of noise.

When

  • 7am – 5pm, Monday 30 July to Friday 10 August
  • 7pm – 5am Monday 6 August to Friday 10 August.

Rail track works

Due to the close proximity of the permanent HV tower 34 to the rail corridor, stringent safety measures are required to protect against train derailment.

Works will be undertaken along a section of rail track alongside permanent tower 34 to install derailment protection infrastructure known as check rails. These works will occur over three consecutive weekends and need to be undertaken at night when trains are not running.

Construction materials required for the works will be delivered to the permanent tower 34 site via Dynon Road.

What to be aware of

  • Delivery of construction materials will require short, intermittent, traffic holds of approximately five minutes of the eastbound lanes of Dynon Road, between Kensington Road and the rail overpass, to ensure vehicles can safely enter and exit the shared access road. Traffic management will be in place to safely direct traffic, pedestrians and cyclists.
  • Works will be undertaken using general power tools, excavators and loaders fitted with noise reduction squawker reversing beepers.
  • These activities are expected to generate medium levels of noise.
  • During out of hours works, construction lights will be used and powered by a low noise generator. We will position lights so they face away from residential properties, where possible.
  • We will notify in advance if there are any revisions to the program.

When

  • 12am – 6am, Saturday 11 August and Sunday 12 August.
  • 12am – 6am, Saturday 18 August and Sunday 19 August.
  • 12am – 6am, Saturday 25 August and Sunday 26 August.

Transfer of HV transmission lines

Relocation of the HV transmission lines is nearing completion. The final transfer of conductors from existing tower 36 to the new permanent tower 36 within the rail freight yard will be undertaken in August.

What to be aware of

To provide access to the HV transmission towers, a closure of a section of the bike lane on the western side of Lloyd Street, between Dynon Road and the first rail bridge, is required. Traffic management will be in place to safely direct cyclists around the work area.

When

  • 7am – 6pm, Friday 3 August to Sunday 5 August.

Hobsons Road site

Works to finalise the relocation of the HV transmission towers will take place within the Metro Tunnel site on the corner of Hobsons and Kensington roads.

Drainage works

New stormwater pits will be installed within the construction site. These works are expected to generate low to medium levels of noise.

Driveway construction

A permanent driveway will be constructed for maintenance access from Kensington Road to permanent tower 33.

What to be aware of

  • A single northbound lane closure on Kensington Road between Hobsons Road and the rail bridge will be required. A shuttle flow arrangement will be in place to safely direct traffic, pedestrians and cyclists around the work area.
  • Access to private properties and businesses will be maintained at all times.
  • These works are expected to generate intermittent periods of medium level noise.

When

  • 7am – 6pm, Monday to Friday
  • 7am – 5pm, Saturdays.

Asbestos removal

Asbestos has been found on the Hobsons Road site previously and we anticipate more asbestos may be found during these works.

The site will be monitored with independent occupational hygienists and removal asbestos will be undertaken by qualified personnel in accordance with WorkSafe Victoria’s Compliance Code 2008 for Removing Asbestos in Workplaces. Removal of asbestos-containing materials by licensed removalists does not pose any safety risk to site staff or the public.

Notifications

Additional information about these works was presented at the community meeting with residents in April (PDF, 3.2 MB).
