president’s Report By the time you receive your first issue of our new journal, Engineering for Public Works, the first quarter of our year will almost be over yet it doesn’t seem that long ago that I made my way across Europe with my wife and daughters during the Christmas break. I was looking forward to inspecting the cobbled streets of Rome that have lasted hundreds of years. At the peak of the Roman Empire, there were over 400,000 km of roads connecting the provinces to Rome and a fifth of these were paved in stone. In Roman Britain, the Romans constructed more than 3,000 km of road with many of these routes still in use today albeit a modern road has been built over the original road. The Romans preferred to go through or over an obstacle and engineered ways of cutting roads into hilly or mountainous landscapes. They were also skilled at bridging rivers and constructing causeways to support a road over marshy ground; skills that our members have enhanced over the years for our benefit today. Change is important. Without it we are not challenged and we cannot grow. Last year was a momentous year of change for me with some planned changes and

other changes that came as a complete surprise. It has made me aware of the need to regularly review where I am at and where I am going and to have contingency plans in place for unexpected scenarios. And change is likely to be ongoing this year with local council elections now behind us as we sift through the effects on our individual members and our council Supporters. Last year, 70% of council CEOs changed and it is predicted that 50% more will change in the year ahead. There will be uncertainty and instability with it but it is our hope that we are able to guide our members through this period. It will be an important time for our new community leaders to communicate effectively with their constituents and stakeholders to ensure their messages are well received. And I am conscious of the need to do likewise – it’s easy to believe people know exactly what you are meaning to say as opposed to what you actually say and how you say it. While a quarter of the year is almost behind us, it is not too late to set goals. I will pay attention to my health – as I hope all of you do; it is not to be taken for granted. I will attend all

Engineering for Public Works | March 2016

of my daughter’s Year 12 major events. I aim to be accurate and pragmatic but not overly purist as I tend to be. Progress is made more difficult when we focus on the text book rather than the desired outcomes and there are often multiple ways to achieve a desired outcome. The best possible route may not follow the text book but may be reasonable, practical and appropriate within the context of a political environment. For all of us in the public works space, ultimately we serve our communities and we naturally aspire to do this in the best possible way even when it is contrary to our natural inclinations. And now this is in print, you can hold me to these commitments. We have conferences coming up in Noosa, Emerald and our state conference in Brisbane, my hometown in November. I hope to see all of you there and perhaps you might ask me about my goals and how well I’ve adhered to them. I look forward to those conversations.

CEO’s Report Welcome to the first issue of Engineering for Public Works, our new journal featuring more technical articles, reports from your branch presidents (as well as our state president) and updates on what’s happening in public works across Queensland. Our next issue to be published in June is on the theme ‘Connecting Queensland’ - in a physical sense with roads, bridges and trains and in a personal sense ie bringing our members together at our branch and state conferences. The State Infrastructure Plan (SIP) released by the state government 13 March 2016 aims to connect Queensland by addressing our state’s infrastructure needs. It includes the prioritisation of projects to respond to the challenges currently facing Queensland and our members. With New South Wales infrastructure development accelerating, we need to ensure we do not lose IPWEAQ members to our southern neighbours and risk not having engineers and skilled workers readily available to deliver public works projects in Queensland in the short and longer term. In conjunction with the SIP, the 15-year Australian Infrastructure Plan confirms the high priority of a number of Queensland

infrastructure projects including the Cross River Rail (CRR) project which aims to transform Brisbane into Australia’s third internationally competitive city and to support critical freight networks. Proposed by the Queensland Department of Transport and Main Roads (TMR), the CRR will extend from Bowen Hills to Salisbury via the Brisbane Central Business District (CBD), Woolloongabba, Dutton Park and Yeerongpilly. Other projects of higher priority include the Ipswich Motorway (Rocklea to Darra), the Port of Brisbane dedicated freight rail connection, reservation of the corridor for the East Coast High Speed Rail (Brisbane to Melbourne), Mount Isa to Townsville rail corridor upgrade, Gladstone Port land and sea access upgrade, Lower Fitzroy River water infrastructure development and the connection of gas suppliers to eastern gas markets. I’m also personally pleased to see the Cunningham Highway will receive an upgrade. Members are invited to submit articles for our ‘Connecting Queensland’ issue with up to 45 CPD points available depending on preparation time and length of the article. I look forward to discussing your ideas, feedback and future themes for

toowoomba’s road to succe ss  

FEATURE ARTICLE                                    

Angela Fry, Principal Project Manager, Project Services Branch, Toowoomba Regional Council reports on their award-winning Toowoomba Outer Circulating Road Project. The project was awarded Overall Winner of the IPWEAQ Excellence Awards 2015. The Outer Circulating Road Victoria Street extension project in Toowoomba’s CBD began as a way to improve traffic efficiency but has achieved outcomes far beyond the original brief. It is driving the transformation of a long-neglected area of Toowoomba’s northern CBD. The project represents much more than a successful engineering outcome: it is a social and economic enabler that has improved the visual amenity of the precinct. It has provided significant safety and flood mitigation benefits to an area devastated by flooding in 2011, and opened the door to future development opportunities. Completed works have delivered improved connectivity and will have an ongoing impact in terms of unleashing economic potential and associated social benefits. The project involved construction of a four-lane extension of Victoria Street, a new Gowrie Creek bridge,

Concept planning began in early 2012 and within 12 months, preliminary and detail design had been completed. Construction commenced in late 2013 and the project was

Engineering for Public Works | March 2016

opened to traffic in June 2015. The project was predominantly state funded, and was considered a milestone project for the Toowoomba Regional Council (TRC). It has been the largest single construction project delivered by the Council in decades, and required enthusiastic and innovative management in order to deliver within the timeframes, under intense stakeholder scrutiny. Council’s innovative stakeholder and engagement approach, which centred on taking the local community on the journey from concept design through to construction, resulted in widespread support and acceptance which could otherwise have been very negative and disruptive. Council successfully harnessed the community and stakeholders as project champions by consistently conveying the project’s social, economic and environmental benefits, and through the development of close working relationships. The design incorporated various engineering disciplines including civil, geotechnical, structural, hydraulic, electrical, landscape and

urban design. The overall design process required engineering personnel to consider a multitude of options to deliver a holistic design solution that addressed Council objectives. The design included three technically complex bridge structures. The Gowrie Creek Bridge is 100 metres long, three spans with constrained vertical and horizontal geometry and of varying skews and tapers. Two 180-metrelong drainage structures were designed and constructed to integrate components of the existing 100 year old bridge at Russell Street. The full length of the project was less than 400 metres and included a four-lane section of road, extensive channel and retaining wall construction and the augmentation and protection of a live trunk sewer system. These were all designed taking into account the extensive technical and social challenges. These challenges included contaminated poor-quality soils, and construction adjacent to live traffic with direct impacts on local residents and businesses. The works were constructed over the confluence of West and East creeks, a high impact flood zone. The characteristics of the creek systems result in peak discharges reaching the work site at similar times. On average, even small storm events (10mm)

The project footprint was extremely constrained, bounded by a National Highway, an active rail corridor, heritage-listed infrastructure, an active business precinct and two major creek systems traversing through the project. The works included relocation and protectionof extensive live and abandoned underground and above-ground services, including water, sewer, power, communication and gas services. Damage to any of these services during construction had the potential to shut down the CBD. The presence of high velocities within West Creek, East Creek and Gowrie Creek combined with highly erodible and contaminated soils required the rigorous analysis of options to address erosion concerns and protection requirements for the finished product. The environmental engineering aspects of the project also had

Gowrie Creek Bridge lights

Engineering for Public Works | March 2016

to be considered in context with Council’s overarching vision for the project. Council’s newly developed Gowrie Creek Catchment Flood Model was used extensively in the design phase to enable the nominal 100-year ARI capacity of the channel to be achieved. During project development, in-depth analysis and assessment of the Gowrie Creek Bridge was undertaken. Initial analysis considered in excess of ten structure configurations which were rigorously assessed for viability against factors such as ability to meet project objectives, construability, long term maintenance impacts, hydraulic performance, sustainability, risk sensitivity and cost. A variety of channel base options were assessed for hydraulic suitability, maintenance minimisation, environmental compliance (construction or raising a waterway barrier) and overall amenity. Concrete-lined channel


base slabs were incorporated in West and East creeks for hydraulic management given the very high flow velocities of the waterways and to form a physical barrier to the poor soils within the creeks. Consideration of alternative retaining wall structures was an integral part of the design process. Not only were retaining structures required to perform a structural function, they were also assessed for their ability to be installed with minimal excavation and interaction with poor ground conditions. The project was managed by Toowoomba Regional Council, designed by GHD Pty Ltd and

constructed by ProbuildCivil Pty Ltd. Harrison Infrastructure Group acted as Superintendent. A team charter was developed and the project was delivered with a ‘best for project’ focus by all parties to ensure key outcomes were achieved. A TRC Project Manager was appointed who managed the project through its entire life cycle, effectively supported by the development of an internal management structure and project steering committee. Council’s graduate engineers were embedded in the construction contractor’s and superintendent’s teams for the construction phase. This provided an opportunity for these graduates to broaden their

skill base and obtain first-hand construction experience. Council supplemented the project team with key staff, including safety, finance, administrative support and stakeholder engagement and communications staff. This has strengthened capability across a broad range of disciplines which will be applied to future Council projects. To ensure the project was successfully delivered within cost, time and budget constraints, effective and efficient planning and control of the program was essential. TRC invested extensive time and effort in considering the most effective delivery methods

for the design and construction of the project. Project risks and opportunities were identified early, with a strong emphasis on finding innovative and effective methods to overcome the extensive challenges associated with the delivery. The project team established a management and reporting structure that ensured all governance, probity and reporting requirements were effectively met, both within Council and to a range of governing state departments. Rigorous monthly assessment and reporting against project management knowledge areas was completed throughout all project life cycle stages. Council prepared monthly status reports focusing on key project management elements and associated exceptions. As part of Council’s overall quality improvement process, interactive learning workshops were held with the designer, contractor and superintendent. Where applicable, learnings identified will be incorporated into Council’s processes and systems to improve future project delivery. Toowoomba City has an abundance of heritage architecture, many of which are on State heritage listings. Russell Street is one of the oldest streets in Toowoomba (circa 1850) and one that the community has

a strong desire to protect and celebrate. Council identified Russell Street, Gowrie Creek and the railway precinct as areas with strong heritage character which need to be protected, enhanced and promoted through effective land use planning and management. These principles formed the foundation for the design and development of the OCR project in particular the landscape and urban design. It enabled these areas to capitalise on the historic character and heritage fabric with more generous public space via a high-quality pedestrian environment and incorporation of hard landscape features to recognise and celebrate the cultural heritage values of the area. Reported as the oldest known existing public urinal in Queensland (Queensland Heritage Register ID: 601381), the Men’s Toilet in Russell Street was located over the proposed Russell Street bridge structure. Council’s commitment to preserving Toowoomba’s heritage values and historic assets resulted in the Men’s Toilet being disassembled (brick by brick) and material stored while construction of the Russell Street structure progressed. Following completion of works in Russell Street, Council reassembled the building (brick by brick) restoring

Council, the local community and the broader region have all benefited from the successful delivery of this project. Council’s overriding imperative is public safety and this project has made a major contribution to Council’s work in building a safer floodresilient city.The project’s funding and delivery model has benefited Council in enabling it to deliver its biggest transport infrastructure project in the region to date. The successful delivery of the project by Council’s Infrastructure Services Group has been acknowledged by many and is paving the way for a number of other large infrastructure projects to be delivered under Council’s umbrella in the Toowoomba region.Toowoomba’s Railway Parklands Priority Development Area which will further transform the former rail yards site into a regionally significant, all inclusive, community asset is underway. It will consist of a generous and integrated series of open spaces for activity, recreation, engagement, interaction and relaxation. An extensive network of pathways, cycleways and new bridge crossings over Gowrie Creek will create the parklands as a destination but also a critical link between areas of Toowoomba long separated by infrastructure and industry.

qldwater ceo’s report Greetings all – hope everyone had a relaxing break. Our First 2016 Technical Reference Group meeting was held at the end of February and we reviewed quite a few discussion papers, fact sheets and project outputs. We are working through web site changes now which will see a number of redundant pages removed, a general refresh and hopefully soon a new compiled resource library which will make it easier to find qldwater documents along with templates and other sample resources from members, and other useful materials we’ve been able to gather. The fifth potential regional water alliance through the QWRAP program (Toowoomba, Southern Downs, Goondiwindi, Western Downs, Balonne, Maranoa) has started to meet and look at collaborative opportunities. DEWS has an increased focus on water security, which has seen some additional elements added to QWRAP scope. It’s worth noting the departure of John Roworth from Longreach back to NSW – John put a great effort into driving the Outback Regional Water Alliance and has been a long-time supporter of both qldwater and IPWEAQ. I’m sure we will continue our tradition of offensive SMS exchange during State of Origin matches.

qldwater has been very active through the Water Skills Partnership, helping members deal with the fairly disruptive introduction of a new VET National Water Package. We continue to promote Operator Certification (both WTP and STP) programs. Through my role on the National Water Industry Skills Taskforce, a new version of the national Framework for drinking water operators will hopefully be published in April, and we are making a new round of representations to the state government on ways of implementing state-wide. There are currently half a dozen operators in Bundaberg going through the process and anyone interested in more information should contact our office. STP Certification is moving, but slowly – there is a real risk that the first operator certified against the Framework developed by Queensland could be from NSW… With the State-wide Water Management System (SWIM) we are focussing on working with the state regulator to improve the KPI reporting processes, and a raft of technical enhancements - I’ve just had my first play with the long-promised mobile device functionality for SWIMLocal users, which is kind of cool – it will ultimately give people in the field a very simple way of recording the data which

Engineering for Public Works | March 2016

ultimately informs their internal planning and gets aggregated f or com pl i an ce re po rtin g. Our 2016 event program is largely bedded down with the first kicking off in Hervey Bay on 13-14 April. Wide Bay Water Corporation has organised an excellent infrastructure tour, and the program of speakers is building. No more little taste tests, just the one big one at our Innovation Forum in September, but as always, you can expect to see new things… Hope to catch up with everybody at IPWEAQ and qldwater events soon. Dave Cameron CEO qldwater - The Queensland Water Directorate qldwater works to strengthen the Water Industry, through leadership, support and representation for its Queensland members. We provide technical input into policy development, guidelines, and coordination to respond to the needs of a changing industry.

wet wipes causing havoc in our sewers

Desire Gralton, Communications Manager, qldwater discovers there’s a problem lurking in our sewers that is costing urban water utilities around the globe hundreds of millions of dollars. While producers of wet wipes continue to market their product as flushable, more and more Australian utilities are speaking out about the enormous problem the products are creating in labour and equipment costs, and damage to ageing infrastructure. In 2014 Sydney Water conducted a behavioural change study on wipes disposal when they started to notice a significant increase in blockages caused by wipes. With a growing environmental and financial risk, the utility was keen to gain a profile of wipe users and the social and traditional media the manufacturers use to target

their audience. Interestingly their research indicated a dramatic increase in younger males aged 15 to 44 being attracted to the texture and appearance of wipes over normal toilet paper. With a quarter of their 4.6 million customer base flushing rather than binning the wipes, Sydney Water is fighting the $8 million per annum problem with a shock campaign featuring an image of a blue whale made of wipes. The whale represents the 500 tonnes – equivalent to four blue whales – of wipe “balls” causing blockages in their system each year.

Engineering for Public Works | March 2016

The shock tactics continue with Hunter Water Corporation recently releasing a photo of a blockage removed by crane and buckets in the Lake Macquarie suburb of Eleebana. Crews used a crane to remove a seven metre “snake” weighing about 750 kilograms, while another 300 kilograms of wipes were removed by crew members using buckets. Last year the Water Services Association Australia (WSAA) convened a forum between the urban water industry and manufacturers and suppliers of hygiene, cosmetics and specialty products to collaborate on short and long term options to reduce the impact of wipes in wastewater systems across Australia. WSAA’s Executive Director, Adam


Lovell, said the Association was pleased that the industry wanted to collaborate on the issue, and that they were collectively working towards a solution that would avoid additional long term costs to water utility customers and adverse impacts on the environment. But while the wipes industry considers ways to better the educate the community not to flush the items (still labelled as “flushable”), the Australian Competition and Consumer Commission (ACCC) has started investigations into the use of the term “flushable” in the marketing of certain products. Queensland Urban Utilities remove around 120 tonnes of wipes from the system every year, and according to spokeswoman Michelle Cull the problem is getting worse. “I think a lot of people just aren’t aware that they

shouldn’t be putting wet wipes down the toilet,” she said. It has become a significant firstworld issue, with Thames Water removing a ten tonne ‘fatberg’ consisting of wet wipes and fat from a London sewer in 2013. The 40-metre long lump of fat damaged a 1940s-era sewer, taking months to repair at a cost of £400,000. In 2014, the corporation spent ten days removing a fatberg the size of a double decker bus from under a major road in south west London. So, is it a problem in your community? If so, are there any innovative solutions you’ve considered? qldwater would be keen to hear your ideas (and any interesting photos relating to the issue) on our facebook page or by emailing Desiré Gralton at dgralton@qldwater.com.au.

The composite fibre technology advantage Wagners CFT Manufacturing started up some 14 years ago based in Toowoomba. Initial testing on their pultruded FTP sections determined they were ideal for the electrical cross arm market. Approaches to power companies soon saw their acceptance and they now supply the majority of crossarms used on power poles around Australia. With such success the team started to test the sections for use in pedestrian and road bridge members, and in 2001, saw the first installation over a creek in Darwin for the NT Parks. Today there are over 350 Wagners CFT – FRP road, pedestrian bridge and boardwalk structures around Australia, New Zealand and as far away as the USA. With ISO9001 Certification it makes Wagners the only truly certifiable, structural FRP system in Australasia. (Engineering Calculations for all sections are available upon request). Wagners have an in house design and engineering team who are trained and dedicated to support engineers from across Australia, New Zealand and Asia in their design endeavours to reach the best performance life expectancy possible for their dollar. Wagners certifications

are carried out by a third party RPEQ Certified Engineer.

Zero maintenance regime of 25 years and a design life expected to be 50 Years for pedestrian structures & 100 years for road bridges Independent testing conducted by the University of NSW for accelerated weathering and life expectancy exceeded 75 years, and that’s before a final finish coat of Vitreflon V700 two pack fluoropolymer paint system is applied. The testing confirms that our use of the highest quality Vinyl Ester resin, and the highest grade

Engineering for Public Works | March 2016

glass fibre, plus the best UV inhibitors and veils available, puts Wagners CFT streets ahead of any other material for longevity and maintenance free performance. The Vitreflon V700 two pack fluoropolymer paint system, has a 25-year paint manufacturer’s warranty and a 40 year expected period to first maintenance, ensureing it will look great for years to come.. Because of all the above engineering and design Wagners are proud to offer a seven-year full replacement warranty on any faulty parts. We will stand proudly behind our product. All of the above contributes to an expected Zero Maintenance Regime of 25 years, and a Design Life expected to be 50 Years for Pedestrian Structures & 100 Years for Road Bridges. “Why wouldn’t you choose the very best for your constituents and their future generations.”

the art of good project management  

FEATURE ARTICLE                                     

Colin Dobie, author of A Handbook of Project Management: A complete guide for beginners to professionals shares his expert tips for successful project management. JOIN RELATED ACTIVITIES TO PRODUCE A PROJECT PLAN People continue to see projects as traditional engineering endeavours and are disinclined to use the same disciplines for greater clarity in other initiatives. For the former let me use the example of building a dam as it happens to be topical at the moment. Among the projects I’ve reviewed or workshopped over the years one of the simplest is dam-building. While there are impacts like geophysical and weather factors, these can be anticipated and allowances made. It causes me grief when I read of dam initiatives that start their implementation phase badly due to inadequate planning when pen is first put to paper. As an example, there is a requirement for a major rethink on water here in my home region of the Southern Downs in Queensland. Water pressure is one issue, given limitations in current supply, but on the Granite Belt there must be

an upgrade to meet expanding urban requirements and the needs of 300+ agricultural producers of, amongst other things, fruit and vegetables. A (albeit desktop) preliminary business case has been conducted as justification to progress to proposals for funding support. I find this business case deficient in most aspects of project management but the authors can be forgiven – ground and future user surveys are yet to be conducted. Even so, poor communication practices and the absence of any risk analysis should be considered unpalatable. It brings me back to my opening premise – the simplest things can be made simpler if we grouped activities together and declared it a project. There are nine areas of knowledge in project management per the global authority, the PMBOK: scope, time management, cost management, quality management, human resource management,

Engineering for Public Works | March 2016

communications management, risk management, procurement management and integration. Queensland recently held elections for local councils and I suspect most candidates did not think to approach the election campaign as a project as it surely is. I do personally know one candidate who did so and was successfully elected mayor of the Southern Downs. My wife, Tracy Dobie, applied her experience in project management which is backed by an Advanced Diploma in Project Management to develop a campaign project plan. Schedules were set with an enddate of 19 March 2016 (project time management) and a KAS (Key Activity Schedule) developed. A budget of $20,000 was set but a contingency of $5,000 was declared for review mid-term (cost management) based on the risk analysis (integration) given anticipated reactions of other candidates. The project management element of ‘quality’ was simple – a clean campaign with demonstrated integrity and no reactions to the tactics of an opponent (risk management) that may be initiated (integration).


Scope was clearly defined, exclusions noted, and related activities (referring to her previous role in local tourism) declared. Initial scope considerations gave cause for refinement of the statement of objective: not simply to win the campaign but to ‘win the majority vote on first count on polling day 19 March 2016. The reason? A risk analysis showed that being placed third of four on the ballot paper meant that the ‘1234’ donkey votes would deliver preferences to the second candidate listed on the ballot paper who was also the main contender. So the objective was to ensure a ‘first past the post’ majority of 50%. This in turn affected the KAS, the need for additional advertising and therefore access to the financial contingency, and so it goes. Risk management was crucial.

Of many factors considered, in politics obviously it will almost always be necessary for a candidate to develop contingencies for a dirty campaign. Mitigation was to do nothing – no reaction, no response whatsoever to support the quality element of the project plan. Again, basic project integration management (scope, quality and risk). The Communications Plan was a major factor in the campaign on many levels. There were several tiers of stakeholders and without covering all details, consultation had to be undertaken with the businesses of the region, residential ratepayers, aged care and youth groups in order to identify all the issues they considered relevant. A support team was established, meeting regularly to keep updated. The general population, all stakeholders, had to be kept informed of strategy, implementation dates and shortterm initiatives. Surrounding shires were part of the communication plan and valuable input was sought and received.

In summary, it was a welldeveloped project plan addressing all nine functions of project management, regularly reviewed and when required, change control mechanisms introduced. It contrasted significantly with the dam preliminary business case I mentioned earlier which was deficient in many areas. And my point? Anyone can use the essentials of project management for any aspect of their life, any milestone, by formulating simple plans that achieve the desired outcome. And the result of the election campaign project? A 56% majority of the vote on first count on polling night. Project plan executed and objective achieved.

The New Way to Treat Odours Responding to odour

complaints, reducing exposure to H2S gas and combating H2S corrosion in sewage systems are ongoing problems for water authorities. Further, the solutions to these issues are by no means perfect, often involving high operational input, temperamental equipment and limited effectiveness. The McBerns Odour Management team has been working with water authorities across Australia and New Zealand for almost 20 years to address these issues. Through this field experience they have developed an innovative solution – Mixed Media Filtration.

A common misconception is that Mixed Media Filtration is the same or similar to carbon only filtration. This is however an inaccurate assertion as Mixed Media Filtration is a multistage process allowing for more comprehensive removal of noxious emissions including H2S and Volatile Organic Compounds (VOCs).

Media Cartridge. It is at this stage that the filtration process truly surpasses carbon only filtration. Here the unique McBerns Media Mix absorbs odours and facilitates chemical conversion. It is this process that is key to the removal of any residual H2S along with other gases and VOCs that have not been captured by the carbon.

The first stage in this process consists of blended, microporous, hyper-absorbent material providing initial odour removal. This is followed by an Activated Carbon adsorption stage further reducing odour concentration. The final stage is the McBerns

Throughout the 20-years of in-field research and development of this method, our foremost objectives have been to achieve class leading odour abatement, simplicity and safety in design and cost effectiveness for customers.

Odour Abatement

The McBerns units -

Cost Effectiveness

The odour abatement potential of Mixed Media Filtration has proven itself time and time again for our customers, often being used where other filtration units have failed. It has been found to be effective under Australian water industry conditions with H2S concentration in excess 1000ppm. On top of this, the unique filtration process allows for the simultaneous filtration of low H2S averages and high H2S peaks without the need for filter alteration. The outstanding performance of Mixed Media Filtration continues to impress our odour specialists, regularly outperforming design calculations.

• need no internal regulation of water or nutrient • do not rely on temperamental living organisms • begin to treat odours instantly • can be disconnected and reconnected with no impact • require little to no automation • are capable of passive filtration (no power required) • have no moving parts • provide increased safety for maintenance staff including less need to deal with hazardous materials • optional remote H2S monitoring

The simple design of Mixed Media Filters allow for significant cost reductions when compared to more complex options which require high capital outlay and often fail to provide an effective solution. Even with the reoccurring consumable cost of media replacement, on average, the net present value over a 10-year period equates to 40% lower than its bio-filter equivalent. Any questions?

LEGAL ARTICLE                                     

The direction of contract management practices within the procurement industry has been driven by the push for efficiency improvements in project delivery, and the need to enhance process and record management. The procurement sector has begun to implement e-contracting and e-tendering to improve coordination and collaboration among contracting parties. With benefit, comes risk. The use of e-contracting creates a number of issues which contracting parties should be mindful of and

need to properly address. If the risks associated with electronic contracting are not properly resolved, then the practical and legal consequences for contracting parties can be serious. What does e-contracting mean? Put simply, e-contracting is a process whereby certain contracting activities take place within a purely electronic environment. Proposed parties to a contract may wish to negotiate and form a contract through electronic means. Once a contract is formed, parties may

wish to electronically administer and manage the contract (for example, to deliver contractual notices or agree to contractual amendments). This also extends to the archiving of project records and communications using an electronic storage medium. Risks and solutions The table below sets out some of the key risks associated with e-contracting (in the main stages of the contracting process) and some of the potential solutions to address those risks.

In cross-border or interstate transactions largely facilitated by e-contracting, what can parties do to ensure certainty of place of contract formation?

Include clauses in the contract where the parties agree to submit to the jurisdiction of the courts of a particular place for hearing and determination of a dispute under the contract.

What steps can parties take to avoid and reduce associated costs of fraud in an electronic environment, such as contracting with a party that does not have the authority to contract?

In Queensland, a party may rely on section 26 Electronic Transactions (Queensland) Act 2001 (Qld) (ETQA) to deny the authenticity of an electronic communication sent without their authority. It is important for contract parties to continue carrying out due diligence processes to correctly identify the person who has the authority to contract

complete streets review   

P R O D U C T R E V I E W                                    

IPWEAQ Technical Products Director, Ross Guppy, explains the review process for the new Complete Streets: Guidelines for Urban Street Design In 1993, IPWEAQ launched Queensland Streets, a design guideline for subdivisional street works. This document served the development industry well for almost 15 years and was considered the most contemporary streetworks design guideline available for a significant portion of that time. However, public policy and debate moved rapidly towards ecological sustainability and community building giving rise to a changing environment within the urban development industry. IPWEAQ’s own charter also moved forward in this regard to recognise the promotion of ecologically sustainable public works and services as a key element in its strategic mission. Having regard to this and the state government’s reform agenda for planning and development as identified in the Planning for a Prosperous Queensland document, IPWEAQ launched a comprehensive review to ensure the inclusion of current Australian and international practices.

The aim in preparing a new Queensland Streets was to produce the most contemporary and innovative neighbourhood and subdivision design guidelines for the Australian market and possibly beyond our shores. Complete Streets was subsequently launched in 2010 and not only provides guidelines for engineers but land use planners and urban designers on what makes quality liveable and/or functional and safe neighbourhoods and subdivisions. The Review IPWEAQ insists on an ongoing collaborative approach for all its publications and services. And this was the case also for the recent review of Complete Streets which process identified the need for additional engineering content to fill the void between the existing Complete Streets document and the old Queensland Streets manual with updated detailed designs. Several different options were considered with conflicting and strong opinions on how best to

Engineering for Public Works | March 2016

proceed. Some users are of the view that urban street design is all about communities and neighbourhoods and they will not therefore use Queensland Streets while others required additional guidance on a range of technical issues such as the width of a residential street. The final outcome is to update Complete Streets incorporating current practices and techniques to deliver a uniform standard of residential streetworks design for use throughout Queensland. That process is underway thanks to the leadership of one of our retired members, John Derbyshire who was involved in the early development of standards (roads, drainage and standard drawings) for LGEAQ and IMEAQ (now IPWEAQ). John has used Queensland Streets extensively and had an interest in town centre design, urban design and leading-edge residential subdivision design (one of the aims of Complete Streets). Members will be offered an opportunity to comment on the revised document. If you have any queries in the meantime however, please do not hesitate to contact me at Ross.Guppy@ipweaq.com.

bundaberg leads adac integration   

T E C H N I C A L A R T I C L E                                    

Dwayne Honor, Manager of Design for Bundaberg Regional Council shares the highlights of the recent ADAC information session held in Bundaberg. The Bundaberg Regional Council (BRC) in conjunction with IPWEAQ recently hosted an information session for 60 participants including surveyors, engineers, developers and construction industry personnel on the implementation of ADAC (Asset Design and As Constructed). Opened by Cr Ross Sommerfeld and chaired by IPWEAQ board member, Dwayne Honor, the session covered the history and development of ADAC and used real world case studies from The Surveying & Spatial Sciences Institute (SSSI) to demonstrate the effectiveness of ADAC when applied in a local government context. BRC’s Manager of Design, Dwayne Honor said, “ADAC provides a robust data specification that underpins asset design and as constructed data. Compliant data is captured during design and construction processes and used to populate asset component registers and Geographical Information Systems (GIS).

“The system captures data from not only within our own region but complements similar data state wide and includes information on roads, drainage, water, sewerage and open space. “As new assets are designed those design components are added to the ADAC database. It then becomes a simplified process for anyone undertaking future design work in locations where assets have already been recorded.” The BRC experience proves the vast majority of projects no longer require the production of constructed drawings. This is due largely to ADAC’s open data transfer via XML and as a result, BRC now expects to fully process a compliant as-constructed submission within 20 minutes including the entry of data into financial, GIS and asset systems. This will deliver significant time and resource savings and in most cases up to five days’ work per submission turning weeks into minutes for developers. BRC have developed a number of tools for use with 12D and have generously offered these tools

to industry for free. BRC has also committed to work towards roundtripping the data by incorporating the survey-accurate data from ADAC into their Dial before You Dig documentation. This is a significant step forward in the successful application of ADAC and is an exemplary model of how the program can and should be used by local governments and organisations. IPWEAQ highly commends the BRC on their successful implementation of ADAC and their desire to help other councils with implementation without the same learning curve. To assist with industry enquiries BRC have set up an ADAC email address (adac@bundaberg.qld.gov.au) for direct access to a number of internal experts covering fields such as design and GIS. IPWEAQ and the Bundaberg Regional Council would like to thank the following organisations for their participation in this valuable industry event: CQ ADAC Working Group Councils; UDIA Bundaberg; Local Civil Contractors; Local Surveyors; Industry Suppliers; Local Engineering Consultants; and SSSI Central Qld Group Members.

Seren McKenzie, Vice President, IPWEAQ and Coordinator, Infrastructure Planning and Design for Lockyer Valley Regional Council shares her experiences as a woman engineer to celebrate International Women’s Day. When I was asked to write something about being a woman in engineering for International Women's Day, I was a little hesitant. After all, it's no big deal - it's just another day and I'm never one to try and draw attention to myself. Then I got to thinking about it; thinking about the board meetings and the training sessions I had been to as an engineer or a female middle order manager. Where were all the women at these sessions? I am still most often the only female in a room full of men or at best one of three women. And I thought a bit more about my experiences in the industry and in the workplace over time. I have had my share of detractors over the years with comments made directly to me or accidentally via email. And this is from men and women who thought I was not experienced or knowledgeable enough about the industry. Was it because I was a female in engineering? Or was it because

I was significantly younger than them? Probably a combination of both but I like to view these experiences as challenges and I prefer to believe I have 'grown' from such situations. Gladly, I can say the negative experiences are far outweighed by the positive experiences. I have had a strong group of supporters who are willing to help when I ask for it, and mentor me formally and informally. Obviously it's important to have supportive superiors which I've been lucky enough to have throughout my career but I've also had the added bonus of being involved with IPWEAQ where I get to catch up with members on a regular basis and don't feel as if I'm treated any differently to any other member. So for me, being a woman in engineering has had its challenges but it's been such a rewarding experience. I've had immense personal and professional growth during my time in this male dominated industry and I wouldn't think of swapping professions. So

Engineering for Public Works | March 2016

should we celebrate International Women's Day? Absolutely! Let's celebrate the ongoing achievements of women and of course all their supporters. Just don't ask me to stand up and make a speech!

DID YOU KNOW? Worldwide, women continue to contribute to social, economic, cultural and political achievement. But progress towards gender parity has slowed in many places. The World Economic Forum predicted in 2014 that it would take until 2095 to achieve global gender parity. Then one year later in 2015, they estimated that a slowdown in the already glacial pace of progress meant the gender gap wouldn't close entirely until 2133. More than 700 female engineers are now registered with the Board of Professional Engineers of Queensland (BPEQ), a 30 per cent increase since this time last year.

S Wq b r a nc h p r e s i d e nt ’s R e p or t As reported in the last Bulletin, South West Queensland branch members were treated to an exceptional conference hosted by the Toowoomba Regional Council in November last year. The SWQ Branch is eternally grateful to Mike Brady and his team and in particular, their secret weapon, Jenny Pendlebury. It set a challenge for our branch committee to meet or exceed the Toowoomba conference

and after much deliberation, we decided to join forces with our south-east counterparts and head for the Sunshine Coast, in particular, the irresistible destination that is Noosa. To be held 28-29 April, the joint conference will be hosted by the recently reformed Noosa Shire Council at The J at Noosa Junction and you can now register online. I am calling on all South West Queensland Branch members to make the effort to

get to Noosa and show our colleagues in the south east how hard we work and play. As the year progresses, we will update SWQ branch members on other branch activities via the new IPWEAQ fortnightly eNews service, Connect. You should feel free though to contact me directly in the meantime. I look forward to seeing you in Noosa! Stephen Hegedus SWQ BRANCH PRESIDENT

Raad Jarjees is the Design Service Manager for the Department of Infrastructure Services at Ipswich City Council. Raad recently participated in an IPWEA International Study Tour, sponsored by the IPWEAQ Foundation and shares his experiences and key learnings from the trip. The 2015 IPWEA International St u dy To ur vis ited nine municipalities in the USA and Europe and attended the APWA (American Public Works Association) International Congress and Exhibition in Phoenix, Arizona. The tour was led by Chris Champion, IPWEA Director International and

included participants from IPWEA Divisions in WA, SA and NSW. Each council provided presentations and tours of their offices, depots and work sites and showcased best practice and innovation, ideas in managing and creating assets, funding initiatives, community consultations, plans for

the future, sustainability and green products. The tour provided an opportunity to think differently about processes, decision making, place making, funding, asset management, leadership, project management and community consultation. It is clear that, like in Australia, each local authority is focused on a sustainable plan for the future to benefit the people and environment in their community.


Councils around the world have become very creative in securing funding for their future capital projects.

Engaging with communities is the key for successful future plans.

Place making and the aesthetics are very important for getting buy-in from the community.

It was quite common for councils to operate outside of common standards and practices to create fit- for-purpose assets that blend well with the environment and are aesthetically pleasing.

Councils focus on resilience, sustainability and services rather than assets.

Not every town must provide a place to live, work and play. Regional plans are a good option.

Acquiring the right talent and providing an atmosphere for talented people to take charge helps steer councils in the right direction.

Dreaming BIG should be encouraged - the community might just support it.

KEY LEARNINGS City of Garland, Texas In Garland, the streets are constructed using 300mm thick reinforced concrete slabs, which appears to solve most of the unsuitable soft subgrade problems. At the same time this method creates problems for service authorities and for the road rehabilitation processes. We were surprised to learn that the expected life of the product is 20-30 years with no intervention. Most of the failure is due to Subgrade issues and joints movement rather than the concrete itself.

Scottsdale has a very advanced traffic management centre which can see and monitor every single signalised intersection. Traffic cameras are positioned everywhere to monitor and manage traffic. Sight detection is used for vehicles and bikes to control traffic phasing and to manage peak hour traffic and emergency detours.

The Garland city uses their own concrete crews and paver to build concrete roads including the kerb. The kerb and the road concrete work are all done at the same time. The subgrade will usually be moisture- stabilized to a depth of up to 1200mm before the concrete is placed on top. There are massive problems however, regarding services, repairs and patching. Recycled concrete is usually used.

City of Rowlett, Texas Rowlett is a very small council and as they can’t afford major industrial projects, they market themselves as the place to rest, relax and play. They have constructed a car park and the infrastructure for a central light rail station which enables the people of Rowlett to use the affordable and fast light rail services to commute between Dallas (the place of work) and Rowlett (the family home). The city has an active community engagement program which includes a free to air TV channel that the mayor and the assistant city engineer appear on every day to take calls and answer questions directly from the public.

City of Scottsdale, Arizona The City of Scottsdale is proud of its open spaces and detention basins to capture and contain water. One basin is designed and used as a park and a BMX play ground. This city is the home town of the first mechanised residential refuse collection truck.

City of Mesa, Arizona This city is aggressively progressing and has completed a number of amazing projects to establish a continuous sustainable funding source for future generations. They have constructed some large baseball

stadiums to accommodate for the spring training of many sports clubs, including a very large stadium for the Chicago Cubs and have lobbied and received funding for a light rail project to connect them with the nearby large town of Phoenix. They have invested heavily in large lakes and super parks to attract more and larger sporting crowds which provide revenue through bed taxes and sales tax. It is a very large scale regional plan and it would not be easy to receive funds for similar projects in Australia. Paris, France In Paris, as well as the bicycle hire system (which has been adopted in Brisbane), we found electrical car hire provided by council for public use. Paris displays aesthetically pleasing gardens and great landscape work and uses bollards intensively to prevent parking on footpaths and road reserves.

factory the council had transformed into a community hub offering social services, library and bank. To preserve its heritage listing, council had renovated the building interior keeping the main faรงade and the old features untouched. City of Antony, France The civil and landscape design plans appear very integrated to accommodate a very functional and aesthetically pleasing town centre. Council is changing the look of the CBD to accommodate for off-road bike lanes but is keeping with the old style of the town roads and road side furniture by doing all design and construction manually. For quick road fixes in Antony, cold mix asphalt is used. Copenhagen, Denmark Cycling is the main mode of transport in the town centre and surrounds. Bikeways are very clearly demarcated as off-road or on-road with a kerb line separating them from carriageways and another kerb line to separate them from pedestrians. There is an atmosphere of a shared zone for cars, bicycles and pedestrians on most of the streets. The rules are very clear: give way to bikes everywhere and at all times.

City of La Courneuve, France This city focuses on sustainable design, construction and maintenance to reduce carbon footprints. One of its schools was designed and constructed with a focus on sustainability during construction and for maintenance and operation of the building. It incorporates solar panels, a vegetation covered roof to reduce the use of central heating and cooling, stormwater harvest and open areas for natural light and breeze. We also visited the Mecano building, a heritage listed Engineering for Public Works | March 2016


City of Køge, Denmark Køge is very big on future planning and the town has some long bikeways, including what they call a super highway for bicycles which is for fast commuters to connect to Copenhagen’s CBD. Every new and old road infrastructure must cater for bike lanes and this is included in a proposed roundabout design:

Køge City Council has constructed new green, sustainable residential apartment buildings with modern design features to capture daylight and stormwater to reduce impact on the trunk systems. Office workstations support sitting or standing work conditions with height adjustable desks to reduce injury time and improve morale by reducing complaints about back pain from long sitting hours. This system has been implemented as standard practice throughout Scandinavian countries since the early 1990s. The City of Frederikssund, Denmark Construction is underway for a green, sustainable community-friendly modern village. Council is proceeding with the implementation of a plan that incorporates residential buildings, bike ways, schools, hospital/clinic, train station,
