Introducing a new way of creating more sustainable infrastructure.

What is IS? IS (Infrastructure Sustainability) is Australia’s only comprehensive rating system for evaluating sustainability across the design, construction and operation of infrastructure. IS has been developed and is administered by the Infrastructure Sustainability Council of Australia (ISCA).

IS aims to: • help in scoping whole-of-life sustainability risks for projects and assets, enabling smarter solutions that reduce risks and costs • foster resource efficiency and waste reduction, reducing costs • foster innovation and continuous improvement in the sustainability outcomes from infrastructure • build an organisation’s credentials and reputation in its approach to sustainability in infrastructure Tenix has been awarded the first design rating for two wastewater treatment plants it is building in North Queensland.

Infrastructure investment Realising the value in investment

by Dr Tim Kannegieter IT IS INCREASINGLY recognised that good infrastructure can have a transformative effect on cities and regions, essentially paying for itself over time through increased vitality of the affected communities. There is no shortage of organisations advocating for smarter, better integrated investment decisions and the need for intelligent investment is generally recognised by government at all levels.

NSW Infrastructure released a 20-year plan late last year with a major shift away from big ticket infrastructure items, such as a major new railway lines, in favour of a wider spread of smaller but smarter solutions that better integrate key transport hubs. The aim is to stimulate economic and urban growth around such hubs.

SKM sustainable design practice leader Phillip Roös presented a paper to the International Urban Design Conference in Melbourne last September on transforming railway stations into sustainable urban centres. The paper discussed how master-planning for stations must “focus on ‘place’ as well as ‘product’ to respond to the multiple opportunities presented by sustainable urban centres, making them destinations and drivers of local economies”.

The paper reflected on the case study of the station master plan of the Tottenham Hale Station in London, where consultancy SKM Colin Buchanan applied opportunistic urban design principles and created a new, significant urban square for north London and a local destination for leisure and investment.

Governments across Australia are now taking this philosophy seriously, exemplified by the $8 billion Green Square urban renewal development in Sydney, centred around the Green Square railway station that was built to link Sydney Airport into the rail network.

Consult Australia chief executive Megan Motto has called

on the federal government to refocus its infrastructure policy on such growth within our cities.

Commenting on the State of Australian Cities 2012 report, Motto said: “Governments must wake up to the fact that planning and funding the infrastructure our cities need to grow and prosper is not a luxury to be indulged only during a budget surplus.”

One of the biggest trends in infrastructure recently has been the drive towards private sector development of infrastructure. The Australian Infrastructure Statistics Yearbook 2012 said there had been an increase in private sector investment in infrastructure from 28% of all infrastructure investment a decade ago, to 44% today.

This trend has primarily been driven by investors seeing an opportunity to meet the demands of industry, particularly in the resources sector which has seen a significant increase in infrastructure to facilitate their operations, such as ports, power and rail.

An infrastructure construction survey carried out by Davis Langdon, an Aecom company, last year found that “60% of private sector authorities expect a rise of investment of at least 10% over the next three years, whereas only 20% of those in the public sector expect to see this level of investment”.

There is a huge variety in approaches to procurement of infrastructure, and Australia continues to develop novel applications. The recent opening of the $655 million Peninsula Link freeway in Victoria is one of the first to be delivered in Australia under the availability public-privatepartnership (PPP) model, according to Abigroup acting managing director David Saxelby. He said: “The project has been of immense importance and interest not only to the organisation, but also to the Victorian government and

Australia invests more in its infrastructure than almost every other major advanced economy, according to the latest figures produced by the Organisation for Economic Co-operation and Development (OECD). Compared to the OECD average of 18.3% of GDP, total public and private infrastructure spending in Australia stands at 26.5% of GDP, second only to South Korea.

Infrastructure investment industry at large due to the funding model under which it was delivered.

“Under the model, the private sector is responsible for constructing, financing, operating and maintaining the road, in return for repayments from the government over an agreed term. The repayments are subject to successful ongoing operations and maintenance, ensuring that road quality and safety remain high priorities.”

The availability PPP has more commonly been used for the delivery of social infrastructure, but is increasingly seen as a way of raising finance for other forms of infrastructure.

This is aligning with a trend towards the development of multibillion dollar strategic projects. Janos Baranyai, national director for major and strategic projects at Meinhardt, said: “[These large projects] are more complex and more challenging. They require more skillsets, they often transcend sectors, involve multiple stakeholders and are often procured and delivered very differently. They require a very specific approach.”

In January, Engineers Australia released Analysing Australia’s infrastructure trends 2013 (http://goo.gl/ax1jQ), a review that revisits its Infrastructure Report Card series that were published in 2010. The report said: “At June 2012, there was work yet to be completed on economic infrastructure valued at $163.96 billion – 2.8 times the value of economic infrastructure work completed in 2011/12. There was also an astonishing $523.52 billion in total engineering construction yet to be completed. Commencements of

total engineering construction work fell to $93.93 billion in 2011/12 (from a peak of $108 billion in 2010/11), though this was nonetheless the third highest year on record.”

A key concern raised in the report was the considerable year-to-year variability in infrastructure activity within states and territories, particularly in the smaller jurisdictions. The report said that economic infrastructure activity in Tasmania and South Australia had contracted since the publication of the 2010 Infrastructure Report Cards. In several jurisdictions there was at least one asset class where little, if any, new activity has occurred.

The report noted that while the engineering workforce had some level of mobility between sectors and regions, most engineers sought continuous employment. The implied concern was that without a steady flow of work, some engineers and companies may leave the industry. This would then make it more difficult to resource infrastructure projects during upswings in activity.

With much work still to be done, it can only be good news for engineering consultants who provide infrastructure services. The market is not restricted to Australia either. A report from the McKinsey Global Institute and McKinsey’s infrastructure practice titled Infrastructure productivity: How to save $1 trillion a year said the global demand for infrastructure between now and 2030, was around US$57 trillion, just to keep up with the projected global growth.

Infrastructure pipeline Five ways to a faster infrastructure pipeline

by Guy Templeton ENGINEERS ARE PIVOTAL to the development of our country’s infrastructure. We have a role in society to bring infrastructure to life. And perhaps for this reason, it is even more obvious to engineers how much Australia needs to have a greater sense of urgency in developing infrastructure.

Infrastructure investment delivers huge benefits for our country – it increases quality of life, creates jobs during construction and operation, and it improves productivity and competitiveness. Yet Australia’s productivity remains a critical issue and we endure bottlenecks that affect movement of both goods and people. Our cities are congested; our transfer of freight between road, rail, air and sea is inefficient; and our interstate links show room for improvement. These gaps would be understandable if Australia was a poor nation, crippled by the global financial crisis. But we are not. In contrast, we have enjoyed 21 consecutive years of economic growth, our country’s balance sheet is the envy of the world, and we have the fourth-largest pool of investable funds in the world, standing at some $1.4 trillion.

In the past year, the number of infrastructure projects on the National Infrastructure Construction Schedule (NICS) website has almost doubled to 103, with a value of over $60 billion. It is encouraging that such projects are identified, but something is stopping us from bringing our capital and skills to bear on bridging our infrastructure gap quickly enough.

Many of the causes are well-documented. Bureaucratic project approval mechanisms; commercial failure of some projects causing wariness to invest; high Australian project costs; community resistance to land-use change and user charging; very few public-private-partnerships (PPPs); governments protecting their credit rating; and historically poor planning of land-use and infrastructure priorities. In addition, the federal government’s Building Australia Fund is close to being used up.

We are investing record amounts in infrastructure but much of this is being spent on catching up on past underinvestment. There is another issue looming that is set to have a major effect on the infrastructure industry – the upcoming decline in resources projects that have done so much to fuel the construction and related industries. The slowdown in mining investment is well known, but we need to look one step further.

The scale of LNG projects in Australia is unprecedented.

Petroleum and LNG project commitments amounted to around $200 billion in 2012, three-quarters of the total resources industry commitments. The LNG projects have another three or four years to run, at which point we risk a massive correction. We need to be doing all we can as a nation now to get the infrastructure pipeline moving faster so we take up that slack and deploy people and capital into valuable projects. We must also ensure the downturn in resources projects is not then compounded by public infrastructure projects slowing through fiscal tightening, especially in the

National project schedule THE NICS WAS created to provide the infrastructure sector with a database of all known and forecast infrastructure investment by all three levels of government. The federal government said NICS has already received nearly two million hits, confirming this information is high in demand both locally and overseas.

A package of improvements to the site has now gone live, making NICS easier to navigate. For the first time, subscribers can also access instant updates about individual projects, as well as information about upcoming projects.

The NICS upgrade also provides an improved project search function and the ability to upload or download all the information on an individual project.

In addition, projects that cross state borders will now be able to be captured through the search function.

states, and a lack of commitment in making the tough calls on issues such as user charging.

Work has begun in many areas to smooth the way for faster, more reasoned and successful infrastructure investment. But we need to be moving faster. Here are five thoughts on the priorities.

1. Infrastructure prioritisation: The formation of Infrastructure Australia and similar state-based bodies has been a great step forward. The states are the delivery arm for most major public infrastructure projects, and we need all states to apply equal rigour in transparently ranking projects within a multi-decade infrastructure plan that is integrated with land-use planning. This ranking needs to be based on objective measures, including cost benefit analysis. We need to take greater care to not get caught in the “ribbon cutting” trap where undue emphasis is placed on large and high profile projects. We can get many projects “shovel ready”, then under way, by focusing on smaller projects, many of which will generate high value productivity benefits. For example,

Infrastructure pipeline for decades there has been debate about the location for an additional airport to serve Sydney, yet so much can be done to improve the current airport’s throughput by modest investments in its transport connections.

2. Slicker approvals processes: We need to make it simpler and faster to get projects approved. We have recently seen the “water trigger” on coal-seam gas projects overturn the move to remove federal/state duplication. We need real action in untying the red tape and green tape caused by multiple jurisdictions’ involvement in the approval process.

3. Removing impediments to the funding flow: We have no shortage of potential funding. It is understandable that governments want to protect their credit ratings but it hinders progress. The biggest impact would come from allowing private sector funding to flow, including that from superannuation funds. Doing so involves looking at the issue in a different way. Private funds have a fiduciary duty to invest in a way that generates a return for their shareholders in excess of the cost of capital. We need to start there and then configure projects such that those returns can be made.

We need government to create an environment of certainty.

If government wishes to unleash private financing, it must set parameters accordingly. The public sector often shows discomfort with those levels of private sector return, but there is no escaping the fact that unless the returns are potentially there, the funds will not flow. The government’s funding can also be usefully increased through direct borrowing for worthy projects, proceeding with asset sales, and the strength

14

of the federal government’s balance sheet can be better used to support infrastructure projects delivered by the states.

4. Adjusting risk allocation mechanisms: Getting projects into a position to attract private sector funding means there must be adequate reward for the risk taken. The risks are simply too high for private funds where patronage risk is present, especially for greenfield developments. In such cases we need government to step up in the early years and assume risk, with a plan for passing an asset to the private sector at a prescribed point.

5. Reducing cost of delivery: Last year, a Business Council of Australia report found that resources projects cost over 40% more to deliver in Australia than in the US. We need to work on labour market flexibility and invest in developing project designers and managers who can keep major projects on track.

We need to promote policies that give access to skilled labour, including via encouraging mobility and allowing skilled migration. The more cost-effectively we can deliver projects, the more bang the country will get for its buck.

For the benefit of all Australians, we must stress the urgency of moving the infrastructure pipeline faster. Engineers need to move beyond the technical domain and have a louder voice on policy by bringing our specialist knowledge to the debate and doing what we do best – getting things done.

Sustainable development Sustainability ratings take off

by Rick Walters IN MARCH 2012, after more than two years of development and much anticipation, the Australian Green Infrastructure Council (AGIC) launched Australia’s, and one of the world’s, first comprehensive national schemes for rating the sustainability of infrastructure. Known as the Infrastructure Sustainability (IS) rating scheme, it incorporates an assessment process, formal rating certification, and an education program. The scheme is designed to drive innovation, contribute to risk reduction and validate industry achievements.

Much has happened in the year since the launch of the scheme. Notably, in March 2013 AGIC changed its name to Infrastructure Sustainability Council of Australia (ISCA) to better reflect the vision and mandate of the organisation.

ISCA is a not-for-profit organisation, supported by a wide base of over 80 members representing organisational stakeholders across the life cycle of infrastructure and associated supply chain; from government agencies to owner operators, delivery agencies, planners and designers, contractors and material suppliers.

Just 10 months after the national launch of the scheme, seven projects to the value of approximately $10 billion had registered to pursue an IS rating, with several others showing interest. The first ratings are expected to be awarded around the time of this publication.

Many infrastructure stakeholders are looking to include the scheme into infrastructure tenders, demonstrating the benefits to industry that the tool brings by establishing a common national framework.

The rating tool development began in 2010 with support and funding from governments, both federal and state, as well as several ISCA member organisations across Australia.

ISCA engaged independent leading experts from a number of disciplines to review national and international best practice and develop assessment categories which were then rigorously tested on pilot projects. Altogether, 16 projects were involved in pilot trials – representing a range of infrastructure types, locations, phases and sizes.

The IS rating tool covers 15 categories within six themes and consists of a scorecard and a technical manual. The categories covered are broad, ranging from environmental issues such as energy and carbon, to social issues such as stakeholder participation, to management issues such as procurement and purchasing.

With a limited existing mix of benchmark reports, sustainability reports, scorecards, performance indicators and indices used across infrastructure sectors, ISCA recognised the need to develop an approach to sustainability that was consistent, practical and useful across the sectors.

The tool therefore provides the ability to rate everything from railways to ports and harbours, bridges and roads, telecommunications, sewers, cycleways and more.

As described by federal minister for infrastructure and

16

IS rating scheme aims • To provide a common national language for sustainability in infrastructure.

• To provide a vehicle for consistent application and evaluation of sustainability in tendering processes.

• To help in scoping whole-of-life sustainability risks for projects and assets, enabling smarter solutions that reduce risks and costs.

• To foster resource efficiency and waste reduction, reducing costs.

• To foster innovation and continuous improvement in the sustainability outcomes from infrastructure.

• To build an organisation’s credentials and reputation in its approach to sustainability in infrastructure.

transport Anthony Albanese at the launch: “In this way, the IS rating tool is for infrastructure what the Green Star Rating Tool is for the building industry … it provides a common language to rank the sustainability of our infrastructure and a common benchmark for monitoring, reporting and improvement.”

Rating tools such as Green Star, NABERS and internationally, LEED, BREEAM and CEEQUAL have enjoyed tremendous success, driving industry transformations to high levels of sustainability performance.

By rewarding innovation and best practice through the IS rating scheme, the infrastructure industry now has greater incentive to demonstrate its capabilities and leadership.

The IS rating tool is accessible to infrastructure developers as well as asset operators, from small scale to large scale infrastructure, from design phase, through construction and operational phases. Projects and existing assets are rated on a 100 point scale. Ratings are based on performance above “business as usual” practice, with three possible IS rating levels: • • •

25 – 49 points is “commended” practice, 50 – 74 points is “excellent” practice, and 75 – 100 points is “leading” practice.

The fees for a certified IS rating are scaled according to the capital value of the project/asset. Some organisations choose to first test the tool on their projects/assets informally using the freely available scorecard on the ISCA website.

In order to upskill the industry in readiness to use the scheme, ISCA has rolled out its IS Foundation Training course across Australia, training more than 160 IS accredited professionals to date. This training will not only help with rating a project or asset, but can also provide a means to more fully understand how to apply sustainability in the context of infrastructure.

Sustainable development Government delivery agencies in particularly are increasingly embracing the IS rating tool. Agencies recognise that the tool draws on the best practice national standards, guidelines, government policy and regulations where sustainable practices are already in place, to ensure consistency and avoid duplication, such as for national energy and greenhouse reporting.

Infrastructure Australia is embedding social, economic and environmental decision-making to deliver infrastructure that provides lasting economic, social and environmental benefits. This triple bottom line approach also underpins ISCA’s approach. This approach to decisionmaking and measuring benefits allows projects and assets to be evaluated on the strength of processes and performance which in turn, can inform project procurement and “upstream” key planning and decision-making activities.

The tool has already been used in the evaluation of options, informing upstream planning as part of early design phases.

As the tool development and refinement is ongoing, the council is inviting organisations to participate in the pilot trial application of IS rating tool for rating the operation of infrastructure assets.

ISCA chief executive Antony Spring said: “Take-up of the rating tool for infrastructure project design and

construction has been positive. However, during the pilot trial process, the tool was only tested on one operating asset.

[Therefore the Operation rating pilot still has] exciting opportunities to be involved in the next progression of the IS rating tool.”

ISCA is also currently in the process of expanding the application of the tool to apply to a range of other sectors.

For example, it is currently partnering with the Institute of Public Works Engineering Australia to adapt the tool to road operations and maintenance programs for local councils. Significantly, 84% of all roads (by length) are maintained by Australia’s 560 local councils.

ISCA is also working with Western Australia Department of Mines & Petroleum to scope out what would be required to use the current IS scheme in the mining sector.

For organisations interested in being part of the ongoing scheme development and collaboration with other member organisations through ISCA networks and events, look to the membership details and benefits on the ISCA website <www.isca.org.au>.

Whitsunday sewage treatment plants $45 million

Whitsunday Region, Queensland Contract: Client: Contractor:

Fixed price design, construct, operate and maintain Whitsunday Regional Council Tenix

Potentially one of the first projects to achieve an Infrastructure Sustainability Council of Australia’s IS (Infrastructure Sustainability) rating is the upgrade of two sewage treatment plants in north Queensland. The Whitsunday Regional Council awarded the contract to design, construct and operate (five years) the Cannonvale and Proserpine treatment plants to Tenix in February 2012.

The new plants will provide significant environmental benefits for the local communities by reducing sewage overflows, improving noise and odour, and reducing the nutrient load discharges to the environment to protect the Great Barrier Reef. They will reduce the annual nitrogen and phosphorus loads in the treated effluent by 28t and 16t respectively, compared to the existing plants. The design of the facilities will allow for population growth in the region for the next 15 to 20 years.

The new designs will include modern technology including enhanced biological nutrient removal (BNR) through Sequencing Batch Reactor (SBR) and Membrane Bio Reactor (MBR) technology. They will also include chemical nutrient removal, mechanical dewatering, odour control, emergency back-up power and remote control.

Tenix is pursuing an IS Design rating for the two plants, 18

building on its involvement in piloting the rating scheme.

The company is striving to incorporate best-practice sustainability initiatives into the design, construction and operation of the plants. The materials used in Tenix’s design have already resulted in a 38% reduction in CO2-e emissions from the client-provided design and an estimated daily saving of 100-300kWh of power compared to typical plant designs. Savings of around 500t of cement in the build have been achieved, along with the selection and use of “green” concrete – substituting up to 30% of cement component with fly ash from a nearby power station.

Resilience Computing infrastructure resilience

by David Singleton ENGINEERS SHOULD RECOGNISE the fact that we must design, construct and manage our infrastructure systems to be more resilient. As engineers and planners, we must now ask ourselves: “What types of events might we face in the future?

What types of events should our infrastructure be designed for?” These events may include: earthquakes, bush fires, drought, tropical cyclones, rising sea levels, storm surges, and floods. We can no longer predict with certainty how severe and how frequent those events will be?

Under such circumstances it appears that we may no longer be able to design and construct in an affordable framework to fully resist such future events using a traditional “factor of safety” approach. We need a way to develop infrastructure designs and coordinate infrastructure systems in order to achieve the most resilient outcome for investment that is warranted economically. The next wave of infrastructure cost benefit analysis must be capable of addressing alternative investments in resilience.

So how can we compare alternative design solutions to assess how they would contribute to a resilient system?

There are several infrastructure sustainability rating tools available: the Infrastructure Sustainability Council of Australia’s (ISCA) IS tool is one. Rating tools not only provide a way to determine an infrastructure asset’s sustainability, they

20

also enable comparison of the sustainability of different assets, or of different design solutions for a single asset. And while the principal use for these tools is to determine the asset’s rating, they can also be used – informally – in “design” mode.

While the tools do not directly address asset resilience in their current formats, they do give some indications. In design mode, the performance of those characteristics that affect the resilience of the asset can be tested and the comparative resilience outcomes identified. It should then be possible to select a design with a reasonable knowledge of its resilience characteristics.

Using ratings tools to understand resilience is an important area for the development of infrastructure sustainability tools.

Significant progress will be made in this direction over the next few years, as ratings organisations (such as ISCA) and universities develop the means to measure infrastructure resilience. These will provide a positive statement about the advantages of sustainability thinking in understanding the resilience of our infrastructure and help us to design, construct and manage our infrastructure systems to be more resilient.

Profession The changing role of engineers

by Matt Coetzee and Steve Richardson AS THE RESERVE Bank of Australia (RBA) has indicated, the Australian economy is reverberating from the impact of a slowdown in mining investment, slowing productivity, the push for tighter government budgets and a high Australian dollar. The RBA’s latest quarterly Statement on Monetary Policy forecasts economic growth of around 2.5% for the current financial year, down from a November forecast of 2.75%.

In this “capital-lite” environment, Australian businesses and federal, state and local governments are looking to optimise the return on their investments. How can we, as technical professionals, support our clients in this environment? We are faced with questions like, how can we optimise the operational efficiency of existing infrastructure? How can we plan for more effective new infrastructure? How do we design a degree of resilience into the infrastructure that will allow it to adapt to a range of future scenarios?

Importantly, how do we ensure that our advice and the projects we work on can, in some way, make a difference towards improving well-being and living standards?

Answering these questions requires that we engineers broaden our role, adding additional services to our traditional planning and engineering design roles. Among others, we are increasingly becoming involved at the early stages of projects, where we can contribute directly to the business and strategic planning aspects.

There are two particular strategic approaches that can be adopted.

Sweating the asset In weaker economic times, most conscientious organisations look at ways of cutting costs – both capital and operational. This reaction is part of the normal business cycle. In particular, the concept of “sweating the asset” has been applied with vigour, firstly, by reviewing the true needs of the entity (be it a company or a government department) and then by auditing the performance of the existing infrastructure against the demands of the revalidated objectives.

Adopting a “sweating assets” philosophy has pros and cons. One clear advantage is that by asking questions upfront about what it is that the client is trying to achieve, and what they already have, we can potentially add value by identifying a “needs” based solution. This often comes at a lower cost because it has a clear focus on the objective, and thereby limits wasted effort. This approach has the obvious advantage of freeing up new investment money towards other projects.

However, as professionals we engineers also need to ensure that we don’t become trapped into a mindset of “mend and make do”. That is, it can become easy to ignore the need for new assets (and associated investment) and simply patch up existing assets used to deliver services.

22

Rather, engineers can assist clients in taking a strategic approach to their assets and help ask the hard questions about what benefit an asset or piece of infrastructure is making towards their business – and what other options are available. Using this approach, we can work in partnership with our clients to help identify “strategic gems” which can be used to inform decisions around how essential projects can proceed.

Land value uplift It is critical to marry the traditional planning aspects with consideration of the funding issues to make the best decisions around infrastructure development. For instance, through measuring the benefits to a property owner of locating close to transport infrastructure, alternative funding mechanisms can be developed to capture some of the benefit to help defray the cost of the original investment.

There is strong evidence showing a clear relationship between transport infrastructure and land value uplift.

Put simply, infrastructure that is built to purpose will result in more demand by people to live nearby. All other things being equal, over time more demand for property results in higher property prices.

The concept of land value uplift is not limited to transport infrastructure – any sort of enabling infrastructure make some form of economic contribution in and around the areas they are built and operated.

The key issue for our public sector infrastructure clients is capturing this land value uplift for the benefit of their projects and the community. While there are several existing models used internationally to capture land value uplift (eg tax increment finance and joint development mechanism), the key issue for our profession is being involved early when these models are being considered.

This is important, simply because land value uplift is a function of the cost of the infrastructure solution and this is affected by where infrastructure is going to go, what it is meant to do and how it will do it – all technical questions in relation to which we engineers should be having a say.

Both the “sweating the asset” and “land value uplift” strategies demonstrate how engineers can be included in upfront project discussions on major infrastructure projects, allowing us to help contribute to the conversation around project feasibility. Th rough this we can provide advice to our clients that bridges the gap between project feasibility, and design and construction and delivery. Through this, we are able to demonstrate our value not only in the quality of our technical advice, but also in contributing to the provision of funding solutions that helps deliver projects that will make a difference.

LAST MONTH IN SYDNEY, industry group Infrastructure Partnerships Australia (IPA) recognised the country’s best projects and financial advice at its National Infrastructure Awards.

The refinancing of Sydney Desalination Plant was awarded the project of the year. The NSW government’s privatisation of the desalination plant in Sydney was a transaction that freed up more than $2.3 billion to help fund a deeper, wider program of infrastructure investment around the state.

IPA chair Mark Birrell said: “The sale of the Sydney desalination plant and the accelerating process to recycle capital out of existing public assets, highlights the broader principles that must be followed if Australia is going to get real projects done.”

The award was presented to Sydney Water Corporation, the NSW government, Goldman Sachs, KPMG, King and Wood Mallesons, GHD, Ontario Teachers’ Pension Plan Board, the Hastings Funds Management managed funds, Utilities Trust of Australia and the Infrastructure Fund.

In the IPA’s award recognising outstanding individual achievement, New Zealand’s deputy prime minister and finance minister (treasurer) Bill English was recognised “for his vision, innovation and leadership in the development of the trans-Tasman infrastructure market”.

Community Focusing on communities

by Romilly Madew RECOGNISING THAT TRUE sustainability cannot be achieved by taking a building-by-building approach, engineers must begin to consider a much larger scale. This is why GBCA has developed and launched the Green Star – Communities rating tool.

The tool was released in pilot phase last June, and addresses sustainability at the precinct, neighbourhood or community scale. It benchmarks and rewards developments by assessing them against a number of categories. It addresses environmental issues, such as minimising energy and water consumption, reducing greenhouse gas emissions, managing waste and reducing dependence on motor vehicles. However, the rating tool also reaches beyond environmental efficiencies to broader holistic sustainability issues, such as economic prosperity, liveability and health.

With support from industry and all three tiers of government, Green Star – Communities aims to encourage the long-term sustainability of soft infrastructure. The “liveability” category, for instance, rewards projects that encourage healthy, active communities through parks, playgrounds, cycle ways and footpaths, as well as through local food production. The “economic prosperity” category encourages projects to consider proximity to employment and education opportunities, and access to high-speed internet. Strategies for improving housing affordability,

developing local skills and enhancing investment in community infrastructure are also encouraged. More than 25 projects – from smaller, infill developments to masterplanned communities which will eventually be home to 100,000 people – are in the process of registering to achieve pilot ratings.

One of those projects is the Barangaroo South regeneration project on Sydney Harbour. Lend Lease is determined to create Australia’s first large-scale carbon neutral community, with centralised precinct services supporting energy efficiency, water recycling and a reduction in waste to landfill. Lend Lease’s vision features a centralised cooling system, including harbour water cooling to eliminate the use of water-intensive cooling towers, a central blackwater treatment plant and onsite renewable energy. Commercial towers are being designed to achieve 6 Star Green Star Design and As Built ratings, and residential developments to achieve 5 Star Green Star ratings.

GBCA is optimistic that we can take the learning outcomes from buildings and scale them up to precincts, communities and, eventually, cities, in order to plan for a more efficient, healthy and sustainable future.

Reconstruction Transport Network Reconstruction Program Queensland

$6.023 billion

Expected completion date: 2014 Client: Queensland Department of Transport and Main Roads Contract type: Collaborative Regional Program Agreement Main contractors: SKM – Far north Queensland; north Queensland (including former northwest Queensland) Opus, Leighton and Arup – Mackay/Whitsunday and Wide Bay Burnett regions MWH and SKM – Central Queensland (including former Fitzroy and central west regions) Aurecon, THG and HIG – Southwest region Aecom and CGI – Metro/Darling Downs regions Aurecon – North coast region The Queensland Department of Transport and Main Roads is delivering the largest reconstruction effort in the state’s history, rebuilding communities, fixing infrastructure and restoring regional economies after flooding and cyclone events in the summers of 2010/2011 and 2011/2012.

In early 2011, 100% of the state was disaster declared with approximately 20,610km of roads closed. Since November 2011, more than 10,890km of state-controlled roads have been closed due to further natural disaster events. Due to the extensive flooding, a review of the damage of the statecontrolled road network was undertaken and an estimate of the reconstruction costs completed.

The 2012 Queensland budget included an allocation of $1.127 billion for reconstruction works. This was in addition to the $4.2 billion already allocated to complete reconstruction works from natural disasters in 2010/11.

There is more than $6.023 billion now budgeted to reconstruct 8545km of Queensland’s state-controlled roads.

The program is being delivered under Natural Disaster Relief and Recovery Arrangements (NDRRA). Under these arrangements, the federal government provides 75% of the funding, with 25% from the Queensland government.

To date, the project has particular challenges due to geographical remoteness and the entire project’s scope, which includes wilderness areas with complex frameworks within Wild Rivers legislations, national parks and the Great Barrier Reef world heritage area. There is also a large community engagement piece to the project, including cultural heritage and Native Title considerations.

Contractors have an obligation to think locally and where appropriate use local suppliers, contractors and services.

Contractors are complying with local industry participation plans and developing local industries by increasing participation and upskilling the workforce.

Through a number of the regions, SKM said some solutions to challenges have included strategic planning for program, procurement, risk and safety management as

28

well as combining projects into consolidated construction packages, which has allowed for efficiencies in the tendering and procurement process. Web-based systems for efficiency and consistency have also been developed along with safety management plans for consistent management approaches across the regions.

Most recent achievements across the whole program include the opening of Somerset Regional Council’s permanent Alf Williams Bridge. The bridge crosses the Brisbane River and was opened last month. The original Alf Williams Bridge, a 67m single lane timber bridge, was completely destroyed in the January 2011 flood and Somerset Regional Council employed an innovative solution for its restoration.

Council acted swiftly and installed a 33m modular temporary bridge just four weeks after the flood event.

The new permanent Alf Williams Bridge is a double lane concrete structure that withstood recent flooding. The permanent Alf Williams Bridge was constructed by local contractor Construction Project Management.

A willingness to look at innovative technology, such as cutting-edge subgrade stabilisation methods, has also been used in the recently completed reconstruction of Hartmann Bridge at Toobeah, 40km west of Goondiwindi. As a result of flooding in the Weir River in January 2011, the central three box culvert cells sank by up to 175mm which resulted in sagging of the bridge deck, making the bridge unsafe. By using Uretek technology – a pressure-injected expanding resin – Goondiwindi Shire Council has achieved both the most durable and best value-for-money restoration outcome. Uretek technology stabilised the subgrade under the bridge to prevent future sinking. It was also used to jack up the bridge and reduce the deflection by about 50%. Replacement concrete work was carried out by local company Tony’s Concrete and Kerb of Goondiwindi.

The precinct will include a 1000-bed correctional centre; a 30-bed secure Mental Health and Behavioural Management Facility; and a 48-bed Supported Accommodation and Program Centre for community-based offenders. The precinct is the first correctional facility in the Territory to include a mental health and behavioural management centre. The project is creating Australia’s largest correctional precinct.

The development includes the design and construction of a low, low-open, medium and maximum security correctional centre and related infrastructure for adult male and female prisoners. The Territory’s project director and contract administrator David West said that emphasis to date has been on design development review to ensure compliance and “fit for purpose”, and work is now well under way on the detailed program for the delivery of critical milestones for the relevant building and commissioning stages.

Sentinel project director Dr Richard Zanner outlined some of the project’s challenges, such as the local industry participation target of 75%. “Darwin is typically a difficult location to resource, and so the consortium has taken

measures to spread their risk by diversifying trades and construction methodologies throughout the project. For example, there is steel work, block work, precast and modular construction activity taking place.”

He said Sitzler Baulderstone Joint Venture has placed strong emphasis on creating and maintaining a culture of safety.

Zanner firmly believes that this “social infrastructure will provide important tools for NT Corrections to assist them in achieving their goals of reversing the pattern of prisoner recidivism that is so prevalent in the Territory”. For example, the Prisoner Interactive Learning System is advanced technology being installed to deliver educational programs.

Then there are industry buildings such as woodwork, metalwork and even a bakery and horticulture facility.

Zanner said: “All of these allow prisoners to remain active and importantly, develop skill sets that might facilitate the expansion of their livelihood options as they reintegrate into society upon completion of their sentence.”

Airports Perth Domestic Terminal 2 Perth, Western Australia

$120 million

Completion: Client: Architect: Main construction contractor: Civil works: Lead engineer for all building services: Operational commissioning: Cogeneration supply and installation:

March 2013 Perth Airport Hassell Broad Construction Services (WA) OPUS Aurecon Arup Clarke Energy

The new $120 million Domestic Terminal (T2) opened in March, less than 18 months after construction commenced in September 2011.

Built by Broad Construction Services (WA), T2 is the first new terminal to be built at Perth Airport for 26 years and marks a critical milestone in its redevelopment program. It represents the first stage in Perth Airport’s vision to have all commercial air services operating in one precinct by 2020.

Perth Airport chief executive Brad Geatches said there was continuing growth in aviation activity to regional Western Australia, driven largely by the resource sector’s fly-in, fly-out workforce model. The opening of T2 represented a major step in meeting the requirements of the resource sector.

Environmental sustainability to maximise energy and carbon efficiencies was a key design consideration for T2. The new terminal features: rainwater harvesting and reuse for toilets and gardens, with 2000m3 of underground storage capacity; underground ducting of ventilation for

airconditioning to reduce energy use; and a sophisticated building management system to reduce energy consumption during operations.

As part of the T2 construction program, Perth Airport has built a cogeneration power plant that will provide power for T2, the Domestic Pier and expanded International Terminal (T1), and reduce greenhouse gas emissions by 55% due to energy savings and the use of gas. The cogeneration plant will operate 24 hours a day and provide reliable back-up power during grid network outages. In addition to using gas to generate electricity, cogeneration will use its heat to power the airconditioning for both terminals. The 4MW plant includes two 2MWe high efficiency gas engines, two absorption chillers and HV switchgear.

The New Parallel Runway project at Brisbane Airport is nearing completion of its first phase of works. The full project will cost around $1.3 billion and will take more than eight years to build. The first phase is focused on delivering drainage upgrades, access roads to facilitate future works and adjustments to the smaller cross runway.

This phase has already seen a number of innovative sustainable practices. These include the recycling of all cleared trees into a topsoil and mulch product that will be used to cover the future airfield, eliminating the need for thousands of truck movements to carry these materials offsite along local roads. An area within the construction site (and within the wider airport Biodiversity Zone) has also been converted into a specific habitat for the endangered Lewin’s Rail bird. Major drains have been benched to facilitate mangrove colonisation within the drain batters, which will assist with bank stabilisation and provide additional estuarine habitat.

This approach will continue into the subsequent reclamation, consolidation and construction phases of the project, which is on target to be delivered by 2020.

Completion: Client: Contract: Main contractor: Designer:

October 2013 Australia PaciďŹ c Airports (Melbourne) Construct only Fulton Hogan Beca

The Melbourne Airport Foxtrot Apron Infill project involves the infill of the existing grass island between taxiways Alpha, Sierra, Yankee and Golf to provide four additional Code C stand-off parking bays, which can also alternatively accommodate two Code E aircraft. The scope of the project involves placement of approximately 30,000m2 of 500mm thick Portland Cement Concrete Aircraft Pavement; installation of six apron floodlighting towers and associated

electrical works; installation of 300m of stormwater drainage including 185m of grated drain; and construction of a new 370m section of watermain line. The project commenced in September 2012 and completion is forecast for October 2013.

Melbourne Airport, in its approach to sustainable solutions, has supported the initiative of implementing LED floodlight fittings for the project. This will reportedly make Melbourne Airport the first airport in Australia to use LED apron floodlights.

LED fittings are more economical and sustainable from a maintenance perspective due to power savings and a longer lifespan than HPS lighting. Installation of the LED floodlight fittings is currently programmed for August.

Narrabri Airport Narrabri, NSW Completion: Client: Contract: Designer: Main subcontractors:

June 2013 Narrabri Shire Council Concept and detailed design Hyder Consulting Gleeson Surveying (surveyors) ARRB Group (pavement strength testing)

Narrabri Airport currently has two runways, a 1524m sealed runway and a 1213m grass runway.

The terminal can accommodate up to two aircraft the size of BAE Jetstream 32 and up to 15 light aircraft on a grassed tie down area. In 2011, the Narrabri Shire Council released a master plan that looked at regional growth and infrastructure requirements. By 2021, the master plan proposes an apron extension to accommodate three aircraft parking stands, the largest of which will be designed for 50-seat aircraft such as the Dash 8-300 or similar. This will accommodate regional passenger transport operations as well as freight operations.

Further to this plan, an investigation, design, and documentation of the airfield upgrade at Narrabri Airport is now being performed by Hyder Consulting.

The upgrade proposal includes a 350m runway extension,

strengthening of the existing pavement (runway, taxiway, and apron), and new airfield ground lighting. The project is currently in the early detailed design phase. Hyder is responsible for all site investigations, geometric design, pavement design, and lighting design associated with this.

In one of the investigations being performed, falling weight deflectometer testing has been used to assess the strength of the existing pavement, and to determine the necessary overlay required.

$762 million 2016 Roads and Maritime Services Design & Construct Thiess Hyder and Aurecon Joint Venture

The Frederickton to Eungai upgrade is the second stage of the 40km Kempsey to Eungai Pacific Highway upgrade. The first stage, the Kempsey bypass, opened to traffic over Easter.

Roads and Maritime Services has engaged Thiess to design and construct the Frederickton to Eungai upgrade, with substantial construction expected to begin in July this year. Once completed, this new section will link up with the Kempsey bypass in the south and the existing dual carriageway section of highway to the north of Eungai Rail.

The upgrade will involve the construction of 26.5km of divided road, including a new interchange at Stuarts Point Road and the installation of safe, modern rest areas on both sides of the highway at Cooks Lane, south of Barraganyatti.

Hyder Consulting and Aurecon have been appointed designers for the upgrade. The integrated design team will provide civil, hydraulic and structural detailed design.

Roads Legacy Way Brisbane, Queensland Completion: Client: Contract: Project team: Joint venture partners: Designers:

$1.5 billion Early 2015 Brisbane City Council Design, construct, maintain and operate (10 years) Transcity Joint Venture Acciona Infrastructure, Ghella and BMD Constructions Cardno, GHD and URS

Legacy Way is a 4.6km road tunnel that will connect Brisbaneâ&#x20AC;&#x2122;s Western Freeway at Toowong with the Inner City Bypass (ICB) at Kelvin Grove. It will provide an alternative route to local roads for traffic leaving the Western Freeway and travelling to and from the ICB. The central infrastructure being delivered by the Transcity Joint Venture consists of two bored tunnels 4.6km long, with a diameter of 12.4m. It will carry two traffic lanes in each tunnel; eastbound and westbound directions.

Transcity is using two Herrenknecht Double Shield tunnel boring machines (TBMs) to excavate Legacy Wayâ&#x20AC;&#x2122;s tunnels.

The TBMs were recycled from parts of the TBMs previously used on CLEM7, resulting in significant time and cost savings to the project. This allowed the tunnelling process to be fast-tracked rather than the alternative of procuring new machines from Germany.

The machines were also refurbished locally, rather than abroad, resulting in expedition of the assembly and launch process. The TBMs, Annabell and Joyce, continue to excavate at record speed. Both have now passed the 3km mark on the twin 4.6km tunnels. This month, it is expected that the projectâ&#x20AC;&#x2122;s first TBM will break through at the eastern portal.

In only six months at the start of the project, a precast manufacturing facility was established to produce 38,700 tunnel precast concrete segments required to line the twin tunnels.

$405 million

Completion: July 2013 Client: ACTEW Corporation Contract: Alliance Project team: Bulk Water Alliance Alliance partners: ACTEW Corporation, Abigroup, John Holland Designer: GHD Key subcontractors: P&T Formwork, Liscon, Geovert, Maas Group, Boral, Lendar, Bleasdale National Contractors, Zenith Workforce, Dale & Hitchcock, Coates Hire, Cardno, Aggreko, BASF, Doka, St George Concrete Pumping, Ausreo, Pipeline Coatings, Lendar and Hazell Bros Following years of severe drought and harsh water restrictions, in 2007 the ACT government endorsed the construction of an enlarged Cotter Dam. The dam is positioned 100m downstream of the original Cotter Dam. At over 80m-high, the Cotter Dam will be the tallest roller compacted concrete dam in Australia, dwarfing its 30m-high predecessor. The new dam will store up to 78GL, nearly 20 times more than the original dam, and will increase overall water storages for the ACT by 35%.

The construction of the Enlarged Cotter Dam commenced in November 2009 and is due for completion in July. The placement of roller compacted concrete for the primary dam wall was completed in December last year, and was considered a major achievement. Other recent achievements on the project include the refurbishment of Cotter Avenue, a grassed, tree-lined road that attracts visitors from Canberra and surrounds. The Bulk Water

Alliance also built the Cotter Dam Discovery Trail at Cotter Avenue, an educational walk and viewing platform to provide information about the dam and heritage of the Cotter area.

The completion of 7km of fish rock habitat was a significant environmental innovation late last year.

The purpose-designed and built rock reefs have been constructed to protect the endangered Macquarie Perch from predation as the new reservoir fills. The completion of the rock reefs represents a world-first in construction: it is the first time rock reefs have been used in a freshwater system to protect an endangered species.

A zoned clay-core, rockfill embankment dam with a height of 113m, Copeton Dam has a storage capacity of 1364GL and was originally commissioned in 1976. It recently underwent a $60 million upgrade which involved constructing a 250m-wide, 12m-deep auxiliary fuse-plug spillway to enable the dam to withstand extreme floods by passing excess water in a staged approach.

The upgrade elements included bulk excavation of the spillway channel involving the excavation by drill and blast of approximately 1.2Mm3 of granitic bedrock, and the construction of a four-bay fuse plug concrete structure including floor slabs anchored to the rock, cutoffs, divider walls, abutment side walls and earth embankments. Works to construct four new fuse plug spillway bays are now complete and the spillway will now only be triggered in the unlikely event of an extreme flood. The project has been completed five months ahead of schedule, on budget, with local jobs, local involvement and great safety and environmental records set.

Water Melbourne Cricket Ground underground recycled water treatment plant Melbourne, Victoria

$24 million

Client: Contract: Main contractor:

Melbourne Cricket Club (MCC) Design, construct and operate Tenix

A 600kL/d Class A recycled water treatment plant has been built underground beside the Melbourne Cricket Ground (MCG) to supply water to irrigate Yarra Park and Punt Road Oval, and for cleaning and toilet-flushing at the MCG. The plant will reduce the MCG’s reliance on drinking water by 50% and remove it from the list of Melbourne’s top 100 water users.

The treatment plant was built underground to preserve valuable surface land use and park amenity. Everyone involved in the scheme wanted the design and construction of the plant to have minimum impact on the park and the public.

Tenix used 3D modelling to minimise the underground plant’s footprint and identify potential construction clashes and construction sequencing, procurement and operations and maintenance issues. The modelling facilitated a 30% reduction in bunker area, 15% reduction in bunker depth and enabled the retention of some significant trees around the site. Specific technology was also chosen to enable the reduced bunker size.

The treatment process consists of screening and grit

removal, biological treatment of the sewage and chemical addition for phosphate removal, filtration via membrane bioreactor and ultrafiltration membrane systems, and disinfection via ultraviolet and chlorination.

Associated infrastructure on the inlet side includes the sewer connection, diversion chamber, a 12m x 4.8m diameter pumping station and a rising main. Other infrastructure includes connections under the concourse to a pre-existing storage tank beneath the MCG. There are also connections to Punt Road storage, a pump station and sludge return gravity line. Tenix is now operating and maintaining the plant for two years on the MCC’s behalf.

Additional source water is required to service the rapid and large increase in growth driven by mining activity in the Pilbara. The Pilbara Cities initiative identified a desalination plant and/or development of the Bungaroo groundwater source as potential supply options. In September 2011, the Western Australian government secured an agreement with Rio Tinto to surrender its annual entitlement of water from the Millstream Aquifer to develop its own alternative water supply from the Bungaroo Valley. By developing this new source, Rio Tinto will free up water from existing sources that can be used to support future development in Pilbara towns. The first stage of work to integrate Rio Tinto’s new Bungaroo Valley water source began in February 2013. This first stage includes construction of 11.3km of water mains, and the construction of a regulating valve complex.

There have been a number of studies of, or encompassing, the business case for sustainability in the built environment, ranging across topics including: organisations; the construction and property development industries; and buildings. However, while many of these studies are relevant to civil infrastructure, a specific business case has not been made for infrastructure sustainability. In examining the business case for infrastructure sustainability, this guideline seeks to redress this shortfall. It explains the meaning of infrastructure sustainability and how it can contribute to shared public and business value, and shows how organisations can track their value pathways to improved shareholder returns and so demonstrate their own sustainability business case.

A proper quality of a track and other infrastructure objects represents a basic requirement for train safety and punctuality.

Most of the physical systems and their components deteriorate over time. This affects performance and may lead to failures. The book provides the readers with the necessary functional knowledge of track behaviour and comprehensively covers the function of the various track components, their interaction as elements of the track system, as well as the interaction of the track with railway vehicles. By presenting important tools for a deep understanding of track-behaviour this book aims to be a reference guide for infrastructure managers and to help them to find ways improving track quality for optimum long-term behaviour.

The completion of TransGrid’s Beaconsfield substation redevelopment last November heralded the end of the world’s first major insitu gas insulated substation (GIS) replacement. The end result is the largest 132kV GIS in the southern hemisphere. Due to a lack of available space on site, congestion of underground services and restrictions in the geography of the site, connections between the two new GIS buildings were completed using gas insulated line (GIL). This GIL was housed on an elevated gantry (9m in

height) – a unique solution and an Australian-first.

Due to a combination of ground conditions, contaminated soil issues, surface water and flooding issues, an above-ground cable management area was built with an ultra-efficient cable route design that allowed for segregation of circuits, control and protection duplication, and segregation of AC and DC cables. The substation was built on top of an Ausgrid cable tunnel, and the site interfaces to Ausgrid’s cable bridge entering the site, so the cooperation and integration with Ausgrid infrastructure was implemented.

To deliver the project, TransGrid developed a tailored procurement strategy, consisting of two rounds of prequalification prior to a competitive tender period. Project management initiatives and unconventional solutions were adapted to provide a capacitor for service ahead of completion of the overall project as to meet system needs.

$160 million

Completion: Client:

Stage 1 – third quarter, 2013 Sydney International Container Terminals, a member of the Hutchison Port Holdings Contract: Construct Main civil works contractor: Laing O’Rourke Designers: Aurecon, Mott Macdonald Main subcontractors: Boral, Liscon, Kadyn Drainage, Quick Plumbing and PSG electrical Sydney Ports contracted the Baulderstone–Jan De Nul Consortium in 2007 to design and construct a new terminal at Port Botany, along with related environmental and community works. The team was supported by consultants Hyder Consulting, Golder Associates and Scott Wilson.

When the base infrastructure was completed last August, Sydney International Container Terminal took ownership of 45ha of the site and awarded Laing O’Rourke with the civil works contract to build the surface infrastructure for the new Port Botany Terminal 3.

Laing O’Rourke is now constructing $160 million worth of civil and rail infrastructure works including the provision of pavement using onsite concrete batching, high voltage

substations, structural support for heavy duty quay and stacking crane systems, rail sidings, drainage and ground improvements.

Once operational, like its sister facility in Brisbane, the terminal will use the latest in technologies and a considerable degree of automation to operate the site.

Patrick Stevedores has signed the lease on the remaining 18ha “Knuckle” area and construction is expected to begin shortly, following the construction tender process.

Communications Pawsey Centre Kensington, Western Australia Completion: Client: Contract: Main contractor: Designers: Main subcontractors:

$70 million

April 2013 CSIRO and iVEC Design & Construct, funded by Education Investment Fund PS Structures Woodhead and Aecom MPM and Nilsen

The Pawsey Centre building, named after pioneering Australian radio astronomer Dr Joe Pawsey, was funded by the federal government’s Super Science initiative.

The project consists of the construction of a 1000m2 supercomputing centre as well as the commissioning of 1 Petaflop of supercomputer, data storage and visualisation equipment. The Pawsey Centre will be operated by the iVEC joint venture between CSIRO and the four Western Australian public universities, and supported by the Western Australian government. The facility will play host to not only the new supercomputing facilities but also expertise to support the SKA (Square Kilometre Array) pathfinder research projects, geosciences as well as other science projects that require supercomputing capability.

The Pawsey Centre has strived for efficiency both

through engineering principles, functionality and operability. As part of the CSIRO geothermal project, the Pawsey Centre supercomputer will be cooled using a renewable geothermal solution known as groundwater cooling. The process involves pumping water with an ambient temperature of around 21°C from the Mullaloo aquifer through an above-ground heat exchanger to provide the necessary cooling effect for the supercomputer, before the water is then reinjected into the aquifer.

National Broadband Network Australia-wide Completion: Client: Construction partners:

$37 billion 2021 NBN Co Syntheo joint venture (Lend Lease Project Management & Construction and Service Stream), Silcar, Transfield and Visionstream

The National Broadband Network is one of the largest infrastructure projects in Australia’s history. It is building a fibre optic, fixed wireless and satellite network to become Australia’s first national wholesale-only, open access communications network that is being built to bring high speed broadband and telephone services within the reach of all Australian premises.

Installing the NBN across Australia is expected to take about 10 years. A wide number of contracts have rolled out in the project.

Within the construction program, Syntheo is delivering the NBN in Western Australia, South Australia and the Northern Territory. Syntheo said last month that it had recently significantly strengthened its resources to continue to deliver infrastructure.

Silcar is responsible for the rollout of the NBN throughout regions of Queensland, NSW and the ACT. Silcar said it is working pro-actively and increasing construction activity to reach its targets.

Transfield said its rollout rates in Victoria have been improving for some time and it was working closely with NBN Co to lift them even further.

Visionstream said it was redoubling its focus on delivery and working closely with NBN Co to meet the expected timetable for Tasmania.

Urban Barangaroo Sydney, NSW

Completion: First building targeted for 2015 Client: Barangaroo Delivery Authority Site details: Three development areas Developer (Barangaroo South): Lend Lease Master planner (Barangaroo South): Lord Richard Rogers Australian design team Barangaroo South: Richard Francis Jones, Andrew Anderson, Sacha Coles, Ken Maher, Tony Caro and Alex Tzannes Construction partner (Headland Park): Baulderstone Landscape architect (Headland Park): Peter Walker and Johnson Pilton Walker Master planner (Central Barangaroo): Skidmore, Owings & Merrill (SOM) and Andersen Hunter Horne

$6 billion Barangaroo is a 22ha harbour-front redevelopment project in the centre of Sydney that will establish new parkland, residential, commercial and hotel accommodation.

The development will join the Darling Harbour precinct to the Walsh Bay precinct, completing the missing link in a 14km harbour foreshore walk from Woolloomooloo to ANZAC Bridge.

Barangaroo is divided into three redevelopment areas: Barangaroo South (7.5 ha); Central Barangaroo (5.2ha) and Headland Park (6ha).

Barangaroo South is the commercial precinct, with three large floor plate office towers, residential apartments, a hotel and shops and restaurants being constructed.

Lend Lease won the rights to develop Barangaroo South in 2009.

Central Barangarooâ&#x20AC;&#x2122;s 5.2ha sits between the new Headland Park at the northern end and the commercial mixed use area at the south. It aims to deliver a collection of open spaces, cultural uses, offices and apartments and is currently at the master planning stage.

At the Headland Park site, currently under construction, Baulderstone has commenced sandstone extraction on with a commitment to sustainability, including 100% onsite reuse. As part of its sandstone management planning, Baulderstone has employed a system that uses conventional 3D modelling with more detailed database capabilities and inventory management. This involves the systematic modelling and tracking more than 600 different types and shapes of blocks prior to cutting, treatment and individual placement.

INFRASTRUCTURE AUSTRALIA APRIL 2013

Urban subdivision in the 2012 Urban Development Industry Awards. Hyder’s best-practice engineering design, innovative environmental and engineering solutions allowed developable land to be optimised by producing level allotments platforms, retention of mature trees within road reserves and minimisation of cut and fill earthworks.

The use of WSUD techniques for the treatment of stormwater runoff helped mitigate development flows and will improve the quality of water entering a neighbouring creek. Runoff is treated via turfed verges, open swales, and separate outlet locations for minor and major stormwater flows.

The construction of the site’s wetlands required a series

of basins, with specific water retention parameters, to ensure the health and longevity of the proposed vegetation and to achieve the required water quality function. During construction it was also realised that the excavated material from the wetlands did not prove sufficient as a source for the clay lining, in line with original design requirements.

It was decided to line the wetlands with a geosynthetic clay liner material comprising two layers of geosynthetic woven material with an intermittent bentonite layer, all needle-punched together. This method of lining guarantees waterproofing and is also considered to be “self-healing” due to the physical properties of the bentonite material.

Elizabeth Quay urban redevelopment Perth, Western Australia Completion: Public space open mid-2015 Client: Metropolitan Redevelopment Authority Managing Contractor: Leighton Contractors and Broad Construction Services ($200 million contract) Forward works contract: Georgiou Group ($50 million contract) Elizabeth Quay aims to return Perth’s focus to the Swan River and is the centrepiece of a plan to revitalise the central business district. The new development will incorporate civic, commercial, residential, retail and cultural attractions, set around a picturesque inlet and connected by promenades and boardwalks.

The redevelopment authority released two sites to the market for a residential and hotel development, and five proponents have been invited to submit a detailed proposal.

Future lots will be sold on a staged basis to meet market demand and achieve a mix of uses. Works commenced onsite in April 2012 with all public works due for completion by mid-2015. Early private building construction will commence

$2.6 billion in parallel with the public works and will continue after this time.

The Western Australian government has committed $440 million to fund the construction of the inlet, roads and services, public domain and the creation of development sites. It is anticipated that the project will attract a further $2.2 billion of private sector investment.

The recent $200 million managing contractor contract involves the construction of the 2.7ha inlet, creation of future development sites and new internal roads as well as the delivery of high quality parks, promenades and an island with a connecting bridge. Inlet construction will commence later this year, with the bulk of inlet excavation due for completion in 2014.

To prepare for the construction of the inlet, Georgiou Group is currently undertaking road works and service infrastructure upgrades as part of a forward works contract.

Georgiou’s contract includes service relocation as well as site remediation and road construction. Forward works are due for completion in January 2014.
