Works on Franklin and A'Beckett streets
Major works on the Metro Tunnel are underway at Franklin Street and A’Beckett Street, supporting the construction of a new CBD underground station with direct connections to Melbourne Central Station.
Franklin and A'Beckett Street will be closed for five years.
Piling and shaft construction
- Piling rigs will drill steel lining into the ground, creating a hole. Spoil is removed and a reinforcement cage is placed inside before concrete is poured, creating the completed pile
- Piling and supporting work will start at the A’Beckett Street shaft site in early August
- 68 piles will be constructed to create the retaining wall of the shaft at A’Beckett Street and are expected to take up to 10 weeks to complete
- Piling and supporting works have been completed Franklin Street.
- These works will be carried out between 7am and 11pm, Monday to Saturday, with the noisiest activities occurring during normal construction hours
- Piling will take place between 7am and 6pm while concrete pouring will be completed by 10pm
- Other supporting activities may continue until 11pm each night, however these are expected to generate only a low level of noise
- Works on Sundays will occur between 7am and 3pm, with hammering for the piling guide wall to take place on 13, 20 and 27 August.
What to expect
Noise and vibration can result from a range of activities and equipment used during pile construction. Common sources of noise include heavy machinery, trucks, piling rigs, power tools and broadband reversing beepers on mobile equipment. There will also be road profiling, spoil haulage and footpath works.
The amount of noise on a construction site may vary at any given time depending on the activities being carried out, however we are required to employ mitigation strategies that comply with the Metro Tunnel's Environmental Performance Requirements (EPRs) to minimise disruption to the community.
Installing ground water monitoring stations
Targeted site investigation activities will confirm modelling of the ground water movement around the shaft locations at Franklin Street and A’Beckett Street
Two site locations have been chosen to undertake investigation works, which will include 20cm bore holes being drilled to a depth of 60 metres. A water pumping test will operate once the depth has been reached. These two locations are contained within our site compounds on Franklin Street
Drilling the boreholes is expected to take up to 10 days per hole and will be completed between 7am and 6pm, Monday to Saturday
The water pumping test will operate for 24 hours over a period of four weeks and will produce only very low levels of noise.
To maintain surrounding roads and the worksite, occasional night shifts may be required to facilitate road, footpath, line marking and signage maintenance
These works are key to maintaining the CBD road network and ensuring works continue safely and smoothly
These works may include the implementation of traffic management (lane closures, speed reductions, etc.)
Gantries will create an enclosed and well lit pedestrian walkway that provides a safety barrier between pedestrians and the construction site. These will be erected on the current walkways on the south side of Franklin Street and the north side of A'Beckett Street. A gantry is already in place on the north side of Franklin Street.
Equipment laydown areas
Equipment laydown areas have been established at Franklin Street - between Swanston Street and Elizabeth Street - and A'Beckett Street on the RMIT half basketball courts and surrounding footpath and road.
These areas will be used to store machinery and equipment for the duration of the Metro Tunnel Project and will support the construction of the shafts and future tunnel works.
Hoarding will be installed around the perimeter of these areas to separate the worksite from pedestrians, vehicles and cyclists.
The footprint of these sites will require changes to parking and loading zones in the area. This site on Franklin Street will also be used as a truck waiting area.
Hours of work
- 7am-11pm, Monday to Saturday
- 7am-3pm, Sundays
Out of hours work
When out of hours works are required, 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.
We will notify residents and businesses if there are any significant changes to the program.
