Works to take place in the Parkville precinct in 2017
Works are required in 2017 ahead of major construction for the Metro Tunnel Project in 2018.
These works are being delivered by a Managing Contractor, John Holland, and include identifying underground services and the relocation and protection of these services:
- Site preparation, including tree protection and removal
- Utility service relocations to move underground services away from where the new Parkville Station and tunnels are proposed to be constructed. These services include power and telecommunications cables, gas pipelines, stormwater drains, sewerage and water pipelines and mains
Informing the design
Before we can relocate or protect these services, we need to undertake site investigations to confirm service locations and inform our designs.
Site investigations are continuing and include electronic detection and non-destructive digging.
This approach ensures we achieve the best design outcomes and minimise construction impacts on the community and the environment.
It is estimated that service relocations in the Parkville precinct will be completed by October 2017. The timing of construction activities is indicative and subject to change.
January to May 2017 – new telecommunications services installed along Grattan Street, Royal Parade, Elizabeth Street, Leicester Street and within University of Melbourne land.
February to July 2017 – new gas pipeline installed along Flemington Road, Pelham Street, Bouverie Street, Grattan Street and within University of Melbourne land.
February to October 2017 – new power conduits along Grattan Street, Elizabeth Street and within University of Melbourne land.
Stormwater, Sewer and Drainage
February to October 2017 – new services along Grattan Street, Royal Parade, Barry Street, Leicester Street, Pelham Streets and within University of Melbourne land.
In order to relocate utility services, there will be changes to traffic arrangements on major roads and some local streets in the area from early 2017, including:
- Lane closures and/or shuttle flow on Grattan Street, Royal Parade, Flemington Road, Pelham Street, Barry Street, Leicester Street and Bouverie Street
- There will be some temporary impacts to parking on Grattan Street, between Royal Parade and Bouverie Street at the works location
- Some temporary short term impacts to parking on Pelham Street, Barry Street, Leicester Street and Bouverie Street\
- Short term road closures on Grattan Street during off-peak periods, including weekends and overnight.
- Changes to bicycle lanes on Royal Parade, Flemington Road, Grattan Street and Pelham Street.
- Parking impacts and traffic management plans are being refined and we will provide more detail prior to works commencing.
- Traffic management will be in place during construction to maintain the flow of traffic and ensure the safety of work crews and pedestrians.
Hours of work
The majority of work will take place during normal working hours:
- 7am – 6pm, Monday to Friday
- 7am – 1pm, Saturdays
Work outside of these hours may be required to complete certain activities.
When out of hours works are considered necessary, we will notify local residents and businesses in advance of these works occurring.
All reasonable efforts will be made to complete works ahead of schedule, subject to weather and ground conditions.
What to be aware of
- Access to private properties and businesses will be maintained at all times
- Pedestrian access will be maintained, detours may be in place
- There may be some noise and dust associated with these works. Strategies will be put in place to minimise disruption to the community.
- A project arborist will be on site to ensure that tree protection measures are put in place and supervise all works occurring within designated Tree Protection Zones.
- Some trees will need to be removed, however we have made every effort to reduce the number of trees to be removed. In keeping with this approach only those trees necessary to allow the relevant works to be performed will be removed and we will have all necessary permits in place for this activity to occur.
- We manage service disruptions in consultation with stakeholders in order to ensure continuity of supply
How will the services be relocated?
There are two techniques that will be used to complete these works.
Open cut trenching
This is the traditional and most popular method for service installation, repair, or replacement. Open cut trench excavation consists of excavating a trench for the manual installation of each piece of pipe. The open cut trench method involves excavating down to the required depth, installing or replacing the service, backfilling and reinstating the area.
A trenchless method of installing underground pipe, conduit, or cable along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. It is suitable for a variety of soil conditions and is used for crossing waterways, roadways, congested areas, environmentally sensitive areas, and areas where other methods are not possible.
