Metro Tunnel

Construction impacts in the Domain Precinct

In delivering the Metro Tunnel Project, we want to minimise the inconvenience and impacts of construction on local communities and the environment.

Environmental Performance Requirements (EPRs) have been developed in consultation with key stakeholders throughout Metro Tunnel's planning process to avoid, reduce or manage construction impacts.

Soil Management

Construction of the new Anzac Station and tunnel requires the excavation of over 1.8 million cubic metres of soil, some of which will be classified as contaminated as per the EPA's classification process.

There are strict rules regulated by WorkSafe and EPA Victoria for how excavated contaminated material must be managed, including processes for identifying contaminants, classifying the material, as well as the methods and procedures for safely removing them from site in accordance with environmental regulation.

As a result, the Metro Tunnel Project has comprehensive soil management systems in place for:

  • Soil testing
  • Classification
  • Handling
  • Removal
  • Disposal

Full details can be found in our soil management fact sheet (PDF, 2.0 MB).

Managing construction noise and vibration

The use of heavy machinery such as rock breakers, excavators, road saws and generators will generate medium to high levels of noise and vibration at various stages of construction.

In some instances, there is the potential for this to have an impact on the comfort of people living or working near construction sites.

Whilst every effort is made to undertake high impacts activities during standard construction hours, this is not always possible.

Prior to works commencing, qualified acoustic consultants assessed noise and vibration levels. This helped to identify which properties may be eligible for temporary alternative accommodation or respite offers in accordance with the Metro Tunnel Residential Impact Mitigation Guidelines for Construction.

Residents who are eligible for temporary alternative accommodation during these works will be contacted by the project team to discuss their individual requirements. Requests for relocation will be assessed on a case-by-case basis.

Ear plugs will be made available to all residents in foyers of nearby apartment buildings.

Tree Management

To enable construction of the temporary tram tracks on St Kilda Road, up to 42 trees will need to be removed.

We understand the significant value the community places on the St Kilda Road boulevard. Each of the trees to be removed has undergone detailed assessment and designs have been reviewed to minimise tree removal as much as possible.

This process has already reduced the number of trees impacted in the Domain Precinct from 224 trees to 170, including 95 trees to be removed on St Kilda Road.

Tree protection zones will be established around trees that are being retained. This will involve fencing around those trees, which will include a delineation to protect the root system.

A qualified wildlife handler will be on hand to conduct pre-inspections of trees requiring removal, and will also be on site when the trees are being removed.

Cross Yarra Partnership (CYP) is developing a strategy for the highest and best use for the timber following tree removal. CYP will transport timbers of longer lengths to a storage facility to enable them to be reused.

The project will increase overall tree numbers in Domain, with replacement trees planted on St Kilda Road and additional trees planted in the precinct.

Replacement trees will be planted in improved soil conditions to encourage growth. The species used on St Kilda Road will be determined in consultation with councils and Heritage Victoria.

See the Planning Approvals page for details of the CYP Early Works Plan approved by the Minister for Planning and Heritage Permits granted by Heritage Victoria.
