September

South Yarra Siding Reserve

Site establishment works in South Yarra Siding Reserve are ongoing.

These works include:

  • Closure of South Yarra Siding Reserve to the public
  • This includes service investigations, installing the site office and workforce amenities, levelling the site, installing temporary fencing, creating access roads within the reserve and setting up environmental controls
  • Generators will be used until a power supply is connected to the site in early 2019
  • These works are expected to generate low levels of noise
  • There will be additional truck movements to and from the site during these works.

These works will see South Yarra Siding Reserve closed for up to four years.

For more information, see the November construction update (PDF, 234.4 KB)

October to late November

William and Arthur streets

Three acquired properties on William and Arthur streets will be demolished to provide access to the construction area.

Initial demolition works are expected to generate high levels of noise, and are expected to take up to three days to complete. All other activities are expected to generate medium levels of noise. Some temporary traffic management will be in place during property demolition

For more information, see the South Yarra October(PDF, 228.8 KB) and November (PDF, 234.4 KB) construction updates.

Until 2019

Osborne Street

Overnight deliveries

The continuous flight auger (CFA) piling rig will be loaded onto a truck and taken from the Osborne Street site before 6am on Monday 12 November.

A new piling rig will be delivered to site before 6am on Tuesday 13 November. We expect these works to generate low to medium levels of noise.

Bored piling works

Bored piles will be installed to construct the walls of the tunnel boring machine (TBM) retrieval shaft

These works are expected to generate medium to high levels of noise, and there will be an increase in the number of trucks accessing the site.

Please note that the concrete pour for each individual pile must be continuous to ensure structural integrity. Once a concrete pour has started, it must be completed and on occasions this activity may need to continue outside normal construction hours. Every effort will be made to ensure they are completed within standard hours.

For more information, see the see the South Yarra October(PDF, 228.8 KB) and November (PDF, 234.4 KB) construction updates.

Ongoing

William Street Bridge and Lovers Walk

Long term closures of William Street Bridge and Lovers Walk are required to construct the eastern tunnel entrance

Traffic and pedestrian detours will be in place.

October

Arthur, William, Chambers, Bond and Chapel streets, and Toorak Road

Removal of on-street parking on Arthur, William, Chambers, Bond and Chapel streets, and Toorak Road.

Further information will be provided to directly affected residents and businesses.

For more information, see the South Yarra October construction update (PDF, 228.8 KB).

October

Lovers Walk and Arthur, William, Chambers and Bond streets

Up to 93 trees will be removed so underground services can be accessed, trucks can manoeuvre safely, equipment and materials can be stored, and construction can begin.

For more information, see the South Yarra October construction update (PDF, 228.8 KB).

September

Osborne Street, within the Sidings Reserve, William Street,

Construction works are continuing in South Yarra throughout September and include:

  • Ongoing site establishment works in Osborne Street
  • Start of site establishment works in the South Yarra Siding Reserve
  • Geotechnical and soil investigations
  • Piling preparation works within the site compound on Osborne Street
  • Guide wall construction and piling within the site compound on Osborne Street.

  • 7am – 1pm, Saturdays (if required)
  • No works on Sundays or public holidays (unless otherwise notified).

For more information, see September Construction Update (PDF, 1.3 MB).

September

South Yarra Siding Reserve and on Chapel, William, Arthur and Chambers streets

Geotechnical and soil investigations are continuing in the South Yarra Precinct to gather further information about ground and environmental conditions.

These works include:

  • NDD and excavation of trench pits to locate underground services
  • Borehole drilling for soil sampling
  • Clearing of some remnant vegetation near the existing rail corridor and on Arthur, William and Chambers streets
  • These works are expected to generate medium levels of noise from boring and the excavation of soil.

From late September

Osborne Street, South Yarra (within the site compound)

Works are underway in Osborne street, South Yarra to prepare the area for piling. From late September, guide wall construction will start, following which bored piling will start to build the walls of the Tunnel Boring Machine retrieval shaft.

Preparatory works include:

  • Removal of obstructions in the ground such as tree stumps and redundant services
  • Using an excavator to remove a layer of topsoil
  • Delivery of materials and piling equipment to site
  • Constructing a piling pad to support the piling rigs
  • Use of vibration rollers on site to prepare the pad for set up of the piling rig
  • Assembly of the piling rig.

Guide wall works include:

  • Regular deliveries of concrete and materials to site
  • Excavating a 1.2m deep and 1.7m wide hole
  • Placing polystyrene in the hole to assist with accurate placement of the piles
  • Adding reinforcement and then pouring concrete into the hole to create the guide wall
  • Spoil removal.

Piling works include:

  • Drilling 154 deep holes into the ground using a piling rig
  • Filling each hole with a reinforcement cage and concrete
  • Trucks removing spoil from site
  • Regular deliveries to site, including rock, concrete and pile reinforcement cages. Traffic controllers will be on site managing traffic flow and ensuring safe access and egress.

What to expect

  • These works are expected to generate medium to high levels of noise
  • There may be some vibration felt by people in local properties. This will be closely monitored. It is being mitigated as much as possible, with the smallest vibration roller being used as practicable.

Until September

Osborne Street

Piling works are expected to commence in early September. Prior to any piling, we need undertake a range of site preparation works. Trucks will be delivering materials to site and removing spoil. These works are expected to generate medium levels of noise.

In line with VicRoads requirements, larger equipment will need to be delivered to site out of hours. These deliveries will arrive on site prior to 6am, park on site and wait until normal working hours to unload the truck. Some parking spaces adjacent to the businesses on Osborne Street may need to be temporarily occupied during these early morning deliveries.

Traffic controllers will be on site managing traffic flow and ensuring safe access and egress.

For more information, see the August-September notification (PDF, 3.9 MB). We will provide more information ahead of piling works commencing.

Until October

Arthur Street, William Street and within the Sidings Reserve

Site investigations on Arthur Street, William Street and within the Sidings Reserve and rail corridor in South Yarra to help inform detailed planning for construction of the eastern tunnel entrance.

What we are doing

  • Non-destructive digging (NDD), which involves using a vacuum truck to excavate carefully into the ground to find, inspect and survey the services.
  • Geotechnical testing in the Sidings Reserve and rail corridor involving a drill rig to investigate ground conditions and confirm the extent of the William Street bridge retaining wall.
  • Backfilling and reinstatement work for each test site.
  • Installation of temporary site fencing along the rail corridor boundary within the South Yarra Siding Reserve.
  • Clearing of some remnant vegetation within the rail corridor to make room for NDD and geotechnical investigations to occur on rail land.

Arthur Street

  • Friday 17 to Tuesday 21 August– NDD and service investigations.
  • Monday 20 to Friday 24 August – geotechnical investigations and drilling activities.
  • Monday 27 August to Friday 14 September - NDD, clearing some remnant vegetation

William Street

  • Friday 17 to Thursday 23 August – NDD and service investigations.
  • Monday 27 August to Friday 7 September – geotechnical investigations and drilling activities.
  • Thursday 30 August to Saturday 8 September – NDD, clearing some remnant vegetation

All geotechnical, NDD and service works will take place between 7am and 6pm, Monday to Friday. We will also need to occupy a number of car parking spaces along Arthur and William streets whilst we complete these works.

Access for traffic and pedestrians

  • Work crews will occupy each test site for a short period and works will be staged throughout the day to minimise disruption to traffic, pedestrians and on-street parking.
  • On-street parking along sections of Arthur sand William streets will be progressively closed to enable traffic flow.
  • Traffic controllers will be in place throughout the works to direct traffic and pedestrians safely around the test sites.

Access to private properties will be maintained, however residents may experience short delays (less than 5 minutes) when accessing their property so that the project team can ensure the area is safe to travel along.

Vegetation clearing

  • Clearing of remnant vegetation within the rail corridor will involve the use of landscaping equipment, such as, mulchers and small excavators.
  • The area will be inspected for the presence of wildlife prior to any works. Any identified fauna will be safely relocated by qualified wildlife handlers.

Noise

  • These works are expected to be low-impact, however there will be intermittent levels of noise generated by non-destructive digging and highlevel noise during geotechnical drilling.
  • There may also be short bursts of high-level noise generated by saw cutting equipment to remove concrete and asphalt and landscaping equipment to clear vegetation.
  • We will take measures to minimise noise from our works wherever possible.
