Transcript of CASE STUDY: Update on Adelaide’s Metropolitan rail upgrade
Adelaide
Metropolitan Rail
Upgrade
Sevan Simonian CEng MICE
Project Manager
A critical part of the SA
Government’s $2B
investment in public
transport infrastructure.
› Design and construction
of rail network
› Belair, Noarlunga and
Gawler Lines
› 6 D&C Contracts in total
› 1 ECI Contract - Facilitate
Adelaide Metropolitan
Rail Upgrade
Why Upgrade?
The Challenges
4
› Highly Compressed Programme – No compromise on
Quality, maintain budget
› Geographic diversity/Community
› Safety and Rail Safety
› Environment
› Interfaces
› Community
4
• Securing Best for Project
Designers & Constructors
• Competing with other large
Projects
•Maintaining Key Personnel for
the life of the Project
Key Points:
Proximity to ARTC

Delivery Models – Pre-ECI
Three D&C Projects
› Belair Line
› 19 Track km
› March – August 2009
› 3 Station Upgrades
› Noarlunga Line Stage 1
› 2.4km – 2 Weekend Occupations
› Nov/Dec 2009
› Gawler Line Stage 1 & 3
› 24 Track km
› May – September 2010
› 6 Station upgrades

Delivery Models – ECI
Three D&C Projects
› Noarlunga Line Stage 2 & 2A
› 32 Track km
› February – July 2011
› Gawler Stage 4
› 54km Track km
› September 2011 – March 2012
› Noarlunga Stage 3 & Ade Yard
› 26 Track km
› January – June 2013
› New Station - Wayville
› Nairne Junction Upgrade

ECI
› RAMP evolves with the Designs
› Agree Rates and Construction Methodologies
› Agree Risk Sharing
› Independent Estimator engaged from the start
› At 70% design gate, package is converted into lump sum price (AS4300)
› Work packages and concurrent design development and implementation
phases, with subsequent learning implemented in following packages assisting
in early transition
8 8
ECI - Value for Money
› NPV Calculations (Whole of Life)
› Value Engineering
› Innovations
› Risk Assignment and management
› Transition to D&C as early as 30% Design =
Program Savings (Brown Field)
› Operational balance between maintaining
PTSOM Operations with Construction Costs
9 9
Design Strategies
10
› Niche Design Resources, Management,
Review and Verification
› Early 3D Rail Track modelling of the
Alignment Enabled Construction planning
and Interface with other Disciplines
10
• Early Establishment of 3D
Spatial Test Alignment
• Coordinated Input from other
projects in Design
•Designers regularly on track
walks throughout design
Key Points:
Design Strategies – Innovation Recognition
Salisbury Crossover SB3
Moved 400m towards Platform
Allows for Rationalization of the Alignment to
Increase Speed to 100km/hr
Design Delivered as a 3D model
Top ballast
Bottom Ballast
Formation
150mm Capping
Design Challenges of the Existing Alignment

Earthworks
15
Earthworks
› Critical to establish ground preparation
› Geotech engineer design signed off
› Formation treatment must be set and established
› Do not deviate
16
Drainage
› Definitive solutions
17
Track Construction – Point of difference
18
Resurfacing

Planning Considerations
› Client Risks/Expectations
› Programme
› Public Perception
› Risk Mitigation
› Meticulous Planning – fatigue, heat, resources
› UNIMAT
› Mission Command – Empower Engineers & Supervisors
