1 Delivering the North West Rail Link Colin Rudd, Deputy Project Director, NWRL David Polkinghorne, Design Team Leader, TJHD November 26, 2013

2 The starting point

3 Project overview $8.3 billion budget Open by late 2019 First stage of rapid transit

4 Bigger than the Harbour Bridge Artist s impression: Kellyville Station street view Eight new railway stations 4,000 car parking spaces A train at least every five minutes in the peak 15km twin tunnels 4km skytrain viaduct 20,000 more tonnes of steel than the Sydney Harbour Bridge.

5 Artist s impression: an underground station More trains, more choice Australia s first fully-automated rapid transit rail system Fast, safe and reliable single deck trains Conversion and upgrade of Epping to Chatswood line The longest rail tunnels built in Australia.

6 Bringing the project to life Widespread community engagement since June 2011 Project aligned with key Government plans, Transport Master Plan Major scope improvements made since June 2011 Fully funded from State budget $806m FY , $4 billion over next 4 Property acquisitions well advanced >85% of transactions completed EIS 1 approved September 2012 ; EIS 2 approved May 2013 Early construction works managing contractor appointed August 2012 Tunnelling contract (TSC) awarded June 2013 Surface viaduct and civils contract (SVC) tenders received August 2013 Shortlist of two consortia for operations (OTS) PPP announced May 2013 On program for the first of the TBMs in ground in 2014

7 Aligned with State strategies State Infrastructure Strategy State Plan Budget Planning Transport Rail

8 The plan: Sydney s Rail Future

9 The plan: delivered in five stages Stage 1 Operational efficiencies Stage 2 Network efficiencies Stage 3 Rapid transit: North West Rail Link Stage 4 Rapid transit: New harbour crossing Stage 5 Rapid transit: Southern sector conversion

10 Artist s impression: Kellyville Station, aerial view Sydney s Rail Future & North West Rail Link

11 Heating and cooling in underground stations. Artist s impression: Castle Hill Station The stations Bus interchanges, taxi ranks, bicycle storage Easy access, kiss-and-ride Safe, well-lit environments, constant CCTV monitoring Passenger screen doors

12 No timetable just turn up and go. Artist s impression The trains Single deck, no internal stairs, three doors per carriage 1,300 capacity Automated, modern technology

13 Clear and constant communications with customers. Artist s impression Automation Safety No. 1 priority Platform screen doors: train operations faster and safer Constant live monitoring by expert train controllers

14 Australia s first fully-automated rapid transit system. Artist s impression: Cherrybrook station aerial view Automation Clear communications Multiple cameras and help points, inside trains and out Staff moving through the system during the day

15 Automation 30 years of operations 588km, 41 lines, 25 cities, 585 stations, 4 continents Impressive safety record Source: International Association of Public Transport, 2011 report.

18 Delivery scope major civil works

19 Tunnelling product requirements Geometry to suit rapid transit operations Convenient locations for access Shallow stations

20 Tunnelling constraints CHERRYBROOK CASTLE HILL SHALE NORWEST BELLA VISTA SANDSTONE CUDGEGONG ROAD ROUSEHILL KELLYVILLE SHALE SHOWGROUND Topography Hills District Creeks, no major watercourse Geology 60% sandstone, 40% shale Existing rail crossing ECRL dive with 5m rock cover Highways M2, Castle Hill Rd Buildings Castle Towers, Norwest Business Park

21 Tunnelling strategy Configuration twin tunnels Fire and life safety Groundwater Space proofing Cross passages Crossover cavern

22 TBMs to be manufactured by NFM, headquartered in France Tunnelling contract $1.15 billion contract Thiess John Holland Dragados joint venture Three portions to provide early access for OTS Contractor Completion date 2017

23 Thiess John Holland Dragados Awarded $1.15 Billion contract in June 2013 Australia s most experienced tunnelling contractors 70% of Australia s major underground infrastructure in last decade 1,200 km of tunnels world wide Delivery of tunnelling and rail projects in metropolitan cities across the world

24 TJHD: Key objective We will deliver a safe, high quality and value for money rail asset, in partnership with TfNSW, on time and on budget.

25 Tunnels and Station Civil scope 15 km TBM tunnels Mined tunnels and rail crossover cavern Cross passages Five stations: civil excavations Two service facilities: shaft excavations
