1. Slide 1. Title
Hello everyone,
My name is Graham Wilson and I lead the infrastructure team for
SAGE Automation.
Sage Automation were employed by Schneider electric to assist
with the installation and commissioning of equipment both inside
the tunnel and on the gantry approaches.
Apologies from John Whittaker our commissioning lead who is
very busy at present and is unable to make it today.
Also like to thank Transcity for the use of photographs in this
presentation.
Lastly to make it clear that Schneider were not involved with the
actual tolling gantry on this project

2. Slide 2 What is Legacy Way Project?
• Legacy Way is a twin two‐lane tunnel under construction in Brisbane.
• Brisbane City Council engaged Transcity (comprising BMD Constructions, Italian
company Ghella and Spanish construction company Acciona) to design
and build Legacy Way.
• The tolled tunnel will be approximately 4.6km in length and will run from the
tunnel portals in Toowong (western end), where the western freeway joins
2

3. Slide 3 What is Legacy Way Project?
• To Kelvin Grove in the eastern end where the Inner city bypass joins.
• The Western freeway will be operated by Transport and Main Roads, with some
shared infrastructure between tollroad and TMR
• The inner city bypass will be operated by Brisbane City Council
• Schneider are responsible for the SCADA, Tollroad Traffic Management and Control
system, and also the Plant Monitoring and Control System

4. Slide 4. System Overview
Here is overview of the SCADA OASYS system
There are around 10,000 I/O points on the project.
I will outline the topology for the Plant Monitoring and Control Systems (PMCS)
4

5. Slide 5. System Overview
The PMCS controls a lot of equipment including
which covers equipment such as Dampers, fans, pumps, light circuits, air quality sensors
and so on.
5

6. Slide 6. PMCS Topology
The diagram shows the PMCS topology. There are
• 3 x Redundant CPU Pairs (TCC & Substation 1000)
• 76 I/O Nodes: Tunnel (62), W/Fwy (8), ICB (4), TCC (2)
• Relies on tunnel Ethernet network

9. Slide 9. PMCS overview
Let’s go back to the PMCS overview.
Taking the jet fan example shown in the photo
9

10. Slide 10. Jet fan example
The SCADA system sends out a command to the relevant CPU cabinet over the PMCS
network
The CPU cabinet then communicates with the relevant Remote Input Ouput module
called RIO module.
The RIO module sends a run output to the relevant switchboard.
The fan motor starts and sends feedback back to the SCADA system that the fan is
running.
10

11. Slide 11. Field cabinets
The photo shows a surface field cabinet containing redundant power supplies and
redundant Remote input output modules.
Each RIO has a connection to each layer 2 switch in the cabinet, so the photo shows two
Ethernet connections per RIO module
11

12. Slide 12. System Overview
So that’s the PMCS example.
Now to look at how the Tollroad Traffic Management and Control Systems (TTMCS)
network has been designed.
The Tollroad Traffic Monitoring and Control systems Incorporates
12

13. Slide 13. Tollroad Traffic Monitoring and Control
The Tollroad Traffic Monitoring and Control systems Incorporates several systems shown
down the right side
13

14. Slide 14. Electronic Signs
Start with electronic signs. The photo shows a single line tunnel message sign
14

15. Slide 15. Electronic Signs
Electronic signs are across the project in the form of changeable message signs, variable
message signs, variable speed limits signs, flashing warning signs, over height warning
signs not forgetting dual aspect traffic signals, all Legacy way equipment uses
controllers with Ethernet connections and IP addresses.
This photo shows variable speed limit signs on the Inner City Bypass
On this project there are two 3 x 18 VMS outside the tunnel and 55 single line vms in the
tunnel.
VMS inside the tunnel will display preset messages.
VMS outside the tunnel will display preset messages and travel time.
There are 27 of the larger type C Variable Speed Limit Signs outside the tunnel , 18
operated by TMR.
15

16. Slide 16. Electronic Signs
Electronic signage will be used for standard tunnel operations and also emergency
closures.
Sign Controllers mounted in local field cabinets have Ethernet ports connected to the
network.
The sign controllers also have digital inputs activated via the Remote input output
modules, remembering that the RIO is also connected to the network.
So the changeable message sign, can be driven through the Ethernet port on the
controller or via a digital input from the RIO.
During an emergency the PMCS has priority. On button implements a complete tunnel
closure.
16

17. Slide 17. Traffic Data
The Tollroad Traffic Monitoring and Control systems Incorporates standard road loops
provided by Juvana with loop interface units provided by excel technology group
There are also five bluetooth devices.
There is one on the Innercity bypass tunnel approach, one on the western freeway
tunnel approach, two Bluetooth sensors installed at the
midpoint of tunnel, one on each direction.
There is also one Bluetooth sensor on Milton Road, which
is the congested road the tunnel will bypass.
This device will be used as a measure to calculate journey
times for vehicles bypassing the tunnel.
As a back up traffic data can be provided by the AID system.
17

18. Slide 18. PA speakers
All of the equipment is IP based including the PA speakers
The Public Address System Manager will use the PA
speakers for:
• Providing voice messages for alerting tunnel users when
required
• It also provides priority breaking‐in over radio rebroadcast
informing to vehicle occupants within the tunnel
• Messages can be ad‐hoc or pre‐recorded
• Messages can be edited and organized based on audio
plans
18

19. Slide 19. help and emergency phones
The help and emergency phones are IP based
The SCADA raises alarms when and handset is picked up and connects the handset to
the help phone system via the phone server.
There are 4 motorist help telephone external to the tunnel and 155 motorist help
telephone in the tunnel
19

20. Slide 20. operation and maintenance phones
The operation and maintenance phones are IP based
And are located throughout the tunnel cross passages and within plant rooms.
20

21. Slide 21. dangerous goods cameras
The dangerous goods cameras, which are IP based Bosch Dinion HD units
The main purpose of the system is to automatically detects dangerous goods placards on
vehicles.
The system consists in of a set of fixed cameras whose video feeds are streamed through
the IP communication backbone to both Tollroad Control Centre (TCC) and Back‐up
Control Centre (BkCC).
21

22. Slide 22 PTZ cameras
And all of the fixed and PTZ cameras inside and outside the tunnel are IP based
There are 270 cameras in total.
22

23. Slide 23 PTZ cameras
And a photo of the Automatic Incident Detection during the smoke tests.
23

24. Slide 24 Challenges
The main challenge within the tunnel has been the number of parallel work fronts taking
place during equipment install.
There were literally hundreds of pieces of equipment such as scissor lifts and site
vehicles in each bore, even with round the clock shift working.
The PMCS commissioning team were working alongside the electrical install teams to
ensure no down time.
24

25. Slide 25 Challenges
Outside the tunnel there is more space to work but then the Queensland weather
comes into play.
Our site utes were some of the 39,000 vehicles damaged in the Brisbane CBD area by
the Hail storm last november
And the photo shows our site compound was also flooded by 400mm of rain in 24 hours
and this has happened several more times since this photo was taken.
25

26. Slide 26 Conclusion
A fully IP based system tunnel system was a godo achievement
The design offers redundancy and will help reduce journey times.
There are many more systems not discussed such as overheight vehicle detection,
radio rebroadcast system
