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

7 7

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
