Mernda Rail Project factsheet: Managing construction impacts

15 Mar 2018

The Mernda Rail Extension Project is committed to supporting the local community through the construction impacts associated with delivering this project.

A key priority and challenge for the construction process is managing and mitigating construction impacts to the local communities near the project area.

As with any major construction project, there are impacts from works such as noise, vibration and increased traffic.

While we are constructing the new rail line, management plans are in place to mitigate the potential effects of:

  • noise and vibration
  • light spill during night works
  • dust and mud
  • traffic congestion.

Key impacts requiring management

Construction of the project is managed in accordance with an Environmental Management Strategy (EMS).

An EMS is a strategy to help the project manage impacts during construction. It guides project decision-making and helps to reduce construction impacts on the community and environment.

How we reduce noise and vibration

During construction, the project team monitors noise and vibration levels to make sure they are within the Environment Protection Authority (EPA) noise control guidelines.

You can find out more about the guidelines at

To minimise potential noise and vibration impacts to local residents, we:

  • limit out-of-hours works
  • use temporary noise mounds and barriers where appropriate
  • use quieter reversing alarms on our vehicles and machines.

Impact of temporary light source during night works

There will be times throughout the construction period when temporary lighting is needed to illuminate an area for the safety of the general public and our workers.

To minimise the potential for any temporary spill from lighting towers, we:

  • keep the amount of light to the minimum necessary for safe access or construction
  • direct light towers away from homes, schools, businesses and public buildings.

Dust management

We use a range of measures to minimise dust from construction activities, including:

  • placing dust monitors at strategic locations
  • wherever possible, planning topsoil removal and levelling on less windy days
  • staging works to minimise exposed areas
  • limiting speeds and using crushed rock on long-term construction access roads
  • covering truck loads and stockpiles for excess soil
  • installation of angled iron at entry points to the work site to minimise dirt and mud on public roads.

Keeping traffic moving

Our works take place on and next to key local and arterial roads. A detailed traffic management strategy is in place to help us minimise impacts to traffic and road users. Our priority is to ensure the safety of all road users and our workers. We will maintain access for emergency services and to private properties at all times.

Our works occur on and next to key local and arterial roads. A detailed traffic management strategy is in place to help us manage impacts to traffic and road users.
