Mernda Rail Project factsheet: Construction noise and vibration management
15 Mar 2018
The Mernda Rail Extension Project is committed to reducing construction noise and vibration where possible while we extend the South Morang line to Mernda.
Noise and vibration
As with any major construction project, noise and vibration are unavoidable. Noise and vibration impacts vary at different stages of construction and at different locations depending on the work.
The main sources of noise and vibration on the project are likely to be:
- rock breaking
- piling and soil compaction
- bridge beam installation
- heavy machinery, generators and power tools.
During construction, bore pile driving is used. These operations can cause noticeable levels of ground vibration. The intensity of the vibrations depends on the ground conditions in the area and distance from buildings.
While ground vibration can be noticeable, all activities have been carefully planned to ensure the safety of the community and to avoid damage to property.
Construction noise monitoring
Prior to construction, we undertook noise monitoring at strategic locations along the rail corridor.
Monitoring sound levels before, during and after construction allows us to assess impacts to local residents and implement mitigation measures.
During construction, we actively monitor 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 epa.vic.gov.au.
We also offer property surveys to the houses and businesses next to our works. This helps us understand the existing condition of the properties before we start works.
How we reduce noise and vibration
To keep construction noise and vibrations to a minimum, we:
- monitor noise and vibration during construction as per Victorian EPA noise control guidelines
- work within approved construction times, generally between 7:00am and 6:00pm Monday to Friday and from 7:00am to 3:00pm on Saturday
- use quieter reversing alarms on our vehicles and machines
- where possible use temporary noise mounds, barriers, enclosures and hoarding at the site of noisy works
- keep our machines in good working order.
If you have concerns or questions during these works, we encourage you to contact the project on 1800 105 105.
Did you know?
Bore piling refers to a process of boring a circular hole into the ground, installing steel reinforcement and filling it with concrete to provide a solid foundation for heavy structures.
