| Development of innovative sewerage system analysis tools for Melbourne metropolitan sewerage strategy |
|
Presented by Mark Falconer of Halcrow and Neil Moody of Urban Water Solutions Pty Ltd, Melbourne, at the Ozwater conference, March 2010
A key aspect of the Melbourne Metropolitan Sewerage Strategy involved the development and application of innovative hydraulic / pollutant modelling and assessment tools that enabled the holistic evaluation of the impacts on the sewerage system resulting from a diverse range of possible future loading conditions, customer behavioural changes, climate change and modifications to the sewerage collection system.
This paper describes the tools created and developed to undertake this analysis and their unique application to the 50 year Melbourne Sewerage Strategy.

| A Review of the Project Management Systems Implemented for the Matangi EMU Procurement |
|
Presented by Angus Gabara and Anthony Oyo at AusRail 2009, Adelaide
The Matangi Electric Multiple Unit (EMU) project has been established to replace the English Electric EMUs running on the Wellington suburban railway system and to increase the passenger-carrying capacity of the network. The project is the region’s largest capital works project for some years and is also the largest project in Greater Wellington Regional Council’s project portfolio. This paper reviews the procurement and project management processes used by Greater Wellington Rail Limited for the procurement of the new fleet of Matangi EMU’s.

| Introducing the next generation locomotive to the Australian rail network |
|
Presented by Noel Ramsey, Frank Szanto and Paul Hewison at Conference On Railway Engineering (CORE), Perth, 2008
This paper describes the introduction of what is now the most powerful and efficient locomotive operating across Australia’s Defined Interstate Rail Network. The locomotive was originally conceived by SCT Logistics after analysing the market and commissioning a study from Halcrow to determine motive power configurations that would best suit their expanding rail business.

| Low Carbon Concrete – Options for the Next Generation of Infrastructure |
|
Presented by Don Wimpenny at Concrete 09, Sydney
Concrete production accounts for approximately 5% of worldwide greenhouse gas emissions. The majority of these emissions derive from the cement binder. Although developments in cement manufacture have led to a significant reduction in CO2 emissions, further substantial reductions will require radical change. This paper summarises the findings of a study of options for ‘low carbon concrete’.

| The use of Steel and Synthetic Fibres in Concrete under Extreme Conditions |
|
Presented by Don Wimpenny at Concrete 09, Sydney
The tunnelling and maritime environments can provide extreme conditions for reinforced concrete. Exposure to aggressive saline water can be combined with design lives of 100 years or more. In recent years, traditional carbon steel reinforcement has been substituted by the use of steel fibres and, more recently, by synthetic fibres for sprayed concrete and precast items, such as tunnel segments. This paper describes some of the factors which have prompted the change from rebar to fibres and includes a detailed consideration of the specific durability design aspects of fibre reinforced concrete use within desalination facilities.
