Parkville Station construction plans
It is proposed that Parkville Station be constructed using a 'cut and cover' technique method, with a roof slab placed over the top of the site. Underground construction activities will take place 24/7 once the roof slab has been installed.
The pedestrian subway beneath Royal Parade is proposed to be mined to minimise disruption during construction to this key transport route.
Areas on top of the University Square car park, Barry Street and along Elizabeth Street have been identified as potential construction support sites while Parkville Station is built.
Key construction activities in Parkville would include:
- Preparatory works, including tree protection and removal, and the relocation of underground services such as telecommunications, water, sewer, gas and electricity.
- Road closures and site establishment.
- Excavation of the station box and connecting tunnels.
- Station structural works and station entrance connections.
- Station architectural, mechanical and electrical fit out.
- Track works and the installation of signalling and communications systems.
- Site remediation including landscaping and public realm works and new road layout arrangements.
The construction of Parkville Station will require Grattan Street to be closed to traffic between Royal Parade and Leicester Street, with the potential for temporary lane closures between Royal Parade and Flemington Road.
During construction, Royal Parade and Elizabeth Street (in the vicinity of the works) will also be restricted to two traffic lanes, plus a tram lane and bicycle lane in each direction.
Proposed construction traffic routes for the Parkville precinct aim to move truck and other construction traffic away from local streets and to major arterial roads such as Flemington Road, Elliott Avenue and Macarthur Road as quickly as possible.
The impacts of additional truck and construction traffic will be managed through the implementation of detailed traffic management plans. However, some access will still be required on a number of local streets adjacent to Grattan Street, including Berkeley, Barry, Leicester and Bouverie streets.
Temporary changes to the public transport network will also be required to build Parkville Station. This will involve rerouting the 401, 402, 403, 505 and 546 bus services around the station works site. Construction of the new tram stop in Royal Parade and related roadworks will also result in short-term disruptions to Route 19 tram services.
Managing impacts in Parkville
A number of mitigation measures, or 'Environmental Performance Requirements', have been proposed to avoid, reduce or manage construction impacts in Parkville.
Some of the recommended mitigation measures for the Parkville precinct include:
- Monitoring dust and air quality, in line with Environment Protection Authority (EPA) Victoria requirements, and addressing air quality requirements for residents, businesses, hospitals and research facilities in the area.
- Maintaining vehicle and pedestrian access to the hospital emergency departments at all times during construction.
- Meeting EPA Victoria guideline noise levels and other relevant noise and vibration standards.
- Minimising impacts to public open spaces including University Square and Royal Parade.
- Preparing and implementing a Tree Protection Plan for the Parkville precinct, addressing the detailed design and construction methodology of the project.
- Undertaking property condition surveys before construction begins to record the existing condition of buildings, including older/heritage homes, hospitals and major institutions in close proximity to tunnels and station construction sites.
- Implementing measures for providing advance notice of significant milestones, changed traffic conditions and periods of potential high noise and vibration activities.
- Ensuring that the design of above-ground structures such as station entrances are responsive to heritage places.
At this stage of planning, it is estimated that construction of Parkville Station will take approximately five years, including early works and fit-out of the station underground.
Project-wide rail systems installation and commissioning will occur after the construction period.
Subject to planning approval, preparatory works will begin in early 2017 with major works commencing in 2018.
