Time to increase the penalties for illegal demolition Dear Readers, Finding the delicate balance between development and heritage protection is an onerous and often thankless task, and more often than not, it involves making decisions which are almost certain not to please everyone. Unfortunately, this means that on occasion, some people decide to disregard planning decisions, laws and other statutes and do what they want. With that in mind, it's critical that our planning laws are both consistent and well enforced - and that the punishment for transgressing those laws and statutes is both rapid and harsh. Not surprisingly, my concern and let's be honest - outright anger about this subject, was sparked by the recent unauthorised demolition of a 140+ year old historic hotel in Carlton in inner-suburban Melbourne. For those who are unfamiliar with the case, the site's developers allegedly had the building demolished despite a council stop work order prohibiting it and, perhaps most importantly, the fact that they did not have planning permission to demolish the building. It's a case that has outraged a great number of people across Melbourne. Indeed, speaking on 774 ABC Radio in Melbourne the following day, Victorian Planning Minister Richard Wynne labelled the developers "cowboys" and said that the 2

Construction Engineering Australia â&#x20AC;˘ Oct/Nov 2016

matter would be referred to the Victorian Building Authority. "It's an outrageous circumstance we find ourselves in where without any demolition permit, or indeed planning permit, these cowboys come along, buy the site for $4.7 million, ignore all of the planning frameworks and just knock the building down," the Minister said. These sentiments were echoed by Melbourne's Lord Mayor Robert Doyle who said he was "outraged" by the destruction. "This is the most brazen and wanton act of destructive vandalism that I've seen in my time as Lord Mayor," he said. While there are obliviously a number of issues that need to be addressed, I believe one of the biggest issues highlighted by this case is the relatively small penalties available to governments and authorities to punish those who flout the law. As an example, the maximum fine available for unauthorised demolition at the Carlton site currently stands at $200,000. Add to this a further possible maximum fine of $750,000 being levied by the EPA for incorrect handling disposal of asbestos (a possibility at this site) and the total of maximum fines able to be levied against the developer is still less than $1 million. Now, while $950,000 might seem quite a hefty penalty, when one considers that the value of this $4.7 million site has now reportedly doubled since the building has been demolished, it is clear that these fines

are nowhere near enough to discourage this kind of behaviour. Perhaps a multiple of 2 or even 4 times that amount might start to have an impact! Considering that it is now too late to do anything about the former Corkman Irish Pub, I would also like to float a couple of suggestions for that particular site, viz: â&#x20AC;˘ mandate that the site must revert to public open space for a period of 10+ years, with landscaping, upkeep and, of course rates and land taxes to be paid by the developers; or â&#x20AC;˘ instruct the developers to rebuild the former building (reusing as much as possible of the non-hazardous recyclable material from the original building) and then prevent any additional development of the site for 10+ years. And just for good measure, if an attempt is made to sell the site, these punitive caveats should pass with the title to any new perspective purchaser. Harsh? Certainly! Too harsh? I don't believe so. I am all for well managed, responsible development, but if we allow it to proceed in an unregulated manner with people actively flouting the law, then the punishment has to be harsh enough to discourage a repeat occurrence.

WA'S DEVELOPMENT CONTRIBUTION POLICY UPDATED

The policy guiding the contribution developers make to community infrastructure when undertaking developments in the State has been updated and is available for public comment. Speaking at the Urban Development Institute of Australia's recent 'Delivering a liveable city for all' event, West Australian Planning Minister Donna Faragher said the updated State Planning Policy 3.6: Development Contributions for Infrastructure would create a more clear and consistent process across Western Australia. "The planning and co-ordination of infrastructure is fundamental to the economic and social wellbeing of all communities," Mrs Faragher said. "Land developers are responsible for contributing towards the cost of this infrastructure.

FUNDING AND PROMOTING CLEAN ENERGY More than 20 grants will be announced in the coming months by the Victorian Government under its $20 million New Energy Jobs Fund grants. Minister for Energy, Environment and Climate Change, Lily D’Ambrosio, said the government had received a strong response from applicants to the Jobs Fund. Ms D’Ambrosio said the applicants provided innovative ideas for projects that supported a clean energy future and helped position Victoria as a leader in new energy technologies. “We’re proud to be rebuilding much needed confidence in the renewable energy industry and look forward to working with

"This updated policy and associated guidelines will simplify and standardise the approach to how development contributions for infrastructure, such as sporting grounds and pavilions and parks and playground equipment, are calculated and implemented. "No matter what suburb a development is in, local governments will have a clear understating about what can be funded, and developers will know what their responsibilities are. "This infrastructure is vital to the creation of sustainable and liveable communities. I encourage everyone to have their say on the updated policy." Draft Scheme Text Provisions have also been prepared to ensure the system for charging development contributions is applied through local government planning schemes. The Minister said the draft provisions would create a better system for planning and charging development contributions, providing certainty to developers, infrastructure providers, local government and the community.

all the successful applicants to grow clean energy jobs and business opportunities.” Ms D’Ambrosio said the fund was a key component of the $200 million Future Industries Fund to support high growth, high value industries, such as the new energy technologies sector. She said those industries were critical to securing Victoria’s future as a competitive, innovative and outward looking economy.

SOLAR SYSTEMS FOR PUBLIC HOUSING IN ADELAIDE Three South Australian-based companies have won contracts to supply and install up to 400 solar photovoltaic systems on public housing properties in the Adelaide City Council area. The State Government has awarded a tender to install up to 200 solar PV systems on the properties and a further 200 of the systems will be installed on new public housing being built in metropolitan and regional areas. The successful tenderers are Cool or Cosy, Suntrix and Zen Energy, and the three contracts are estimated to support approximately 75 jobs. The $2 million project is funded through the $65 million public housing package announced in the 2015-16 State Budget. When announcing the successful tenderers on 23 August, Acting Housing and Urban Development Minister, Martin Hamilton-Smith, said the project formed part of the government’s commitment to a sustainable low carbon future and the Carbon Neutral Adelaide initiative. Mr Hamilton-Smith said the project delivered and extended an election commitment to create a pilot program to install solar PV systems on 200 Housing Trust homes. The Minister said if the pilot was successful, Renewal SA would look to expand the program further on new public housing. “Installing solar panels will be an important step in reducing living costs for some of South Australia’s most vulnerable citizens, while contributing towards making Adelaide the world’s first carbon neutral city. “As well as providing substantial savings on electricity bills for public housing tenants, these contracts will also support about 75 local jobs within the local solar industry.”

MELBOURNE RETAINS ‘WORLD’S MOST LIVEABLE CITY’ TITLE “To retain the title of World’s Most Liveable City for six consecutive years is a fantastic accolade for Melbourne, and something of which we should all be proud.” Lord Mayor, Robert Doyle, commenting on the decision of the Economist Intelligence Unit (EIU) to rank Melbourne the world’s most liveable city for the sixth consecutive year. Lord Mayor Doyle said the EIU Liveability Index was the world’s most widely accepted ranking of liveability, comparing 140 of the world’s major cities. “Once again, we excelled in the five criteria: stability, healthcare, culture and environment, education and infrastructure. “We do not take this title for granted and are constantly planning and implementing policies that will continue to improve our quality of life.” Melbourne placed first ahead of Vienna and the Canadian cities of Vancouver and Toronto. Adelaide was rated equal

fifth most liveable city, tied with Calgary, Canada. The Lord Mayor said the City of Melbourne continued to work with all levels of government to ensure the city remained a great place to live. “It is an exciting time in Melbourne: we’ve got many major infrastructure projects underway including the Metro Tunnel and the proposed renewal of the Queen Victoria Market precinct. “It’s also the little things that make a big difference: planting more trees, recycling stormwater, making more parks and green spaces, providing better paths and connections for pedestrians and cyclists, as well as embracing technology and data to improve our operations.”

Victoria’s Premier, Daniel Andrews, said the data proved Melbourne was a great place to live, visit or invest. Mr Andrews said it was the fastest growing city in Australia, welcoming 70,000 people who had voted with their feet and chosen to call Melbourne home in the past year alone. He said retaining the title of World’s Most Liveable City was further proof there was no city on earth quite like Melbourne. “We’ve once again outperformed some of the world’s best cities when it comes to healthcare, education, infrastructure, culture and environment, and sport. “We’ve got something for everyone and the best of everything in Melbourne. Our title proves it.”

AUSTRALIAN GREEN LEADERSHIP IN THE REGIONAL SPOTLIGHT Australian leadership in green building has been applauded by the World Green Building Council, with one engineering firm and two Green Star projects named finalists in the Asia Pacific Leadership in Green Building Awards. Three businesses and nine projects across the Asia Pacific have been shortlisted for the biennial awards, which celebrate leadership in sustainability. “Hot on the heels of last week’s GRESB result, which confirmed Australia’s ‘unbroken leadership’ in sustainable property, we have three new examples of why our industry continues to challenge boundaries, question the status quo, and accelerate the sustainable building movement,” says the Green Building Council of Australia’s Chief Executive Officer, Romilly Madew. Cundall has been nominated in the Business Leadership in Sustainability Award category, and will compete with Hong 6

Kong’s Henderson Land Development and India’s Delhi Metro Rail Corporation. “Cundall has a team of highlyexperienced Green Star Accredited Professionals who are rock-solid in their commitment to sustainability, and are actively pushing the envelope and challenging the industry to demand more and deliver more,” Ms Madew says. Floth Australia’s headquarters at 69 Robertson Street in Brisbane has been named a finalist in the Sustainable Design and Performance – Commercial category, alongside buildings in Singapore and New Zealand. “Floth achieved the first 6 Star Green Star – Design & As Built v1.1 rating in Australia. This is about more than achieving a ‘first’ – it’s about understanding that a certified sustainable building can attract quality tenants, reinforce a company’s brand and futureproof its assets,” Ms Madew says.

The University of Queensland’s Global Change Institute is a finalist in the Leadership in Sustainable Design and Performance – Institutional category, and will compete with other public buildings in Hong Kong and Korea for the coveted prize. “The Global Change Institute is one of Australia’s first net zero energy and carbon buildings, and is a working test case for a range of sustainability innovations. This living laboratory shows us that zero carbon isn’t something we can work towards in the future – it’s happening right now,” Ms Madew adds. Terri Wills, the WorldGBC’s Chief Executive Officer says the growth of green building across the Asia Pacific is in response to “significant population growth, environmental pressures and the strengthened business case.” Winners will be announced at the India Green Building Council’s annual Congress in Mumbai during October.

$100M GOVERNMENTLED HOUSING CONSTRUCTION IN PIPELINE FOR QUEENSLAND The Queensland State Government is backing in the state’s building industry with $100 million worth of Government-led housing construction currently underway or set to commence. Queensland Premier Annastacia Palaszczuk said this significant body of work would provide job support for approximately 2,000 tradespeople throughout the state.

“These are real jobs for local tradies working on building sites in regions all around the state. “The projects will see more than 400 new homes built before the end of June next year. “It means millions of dollars will be injected into local economies, including: almost $9.5 million into Ipswich; over $21.5 million into Townsville, and $19.4 million for the Gold Coast. “Additionally there’ll be boosts of: $2.7 million into Rockhampton; $6 million into Toowoomba; about $5.6 million into the Redlands; over $5 million for the Sunshine Coast and nearly $3.5 million into Pine Rivers," Premier Palaszczuk said. Minister for Housing and Public Works Mick de Brenni said that importantly, the developments will provide homes for hundreds of vulnerable Queenslanders. “Providing safe, secure affordable housing for people who need it, is the reason we’re undertaking this investment,” he said. “These homes are built to high standards of accessibility, which is important when

it comes to making sure that our seniors and Queenslanders with a disability have a secure place to live in communities across the state. “Not only will these projects provide people with a safe, secure place to live, but they will also help supply an income for thousands of workers.” Minister de Brenni said the pipeline of Government-led housing construction builds on the projects already completed this financial year. “We’ve already seen more than $7.7 million worth of new housing completed across Queensland,” he said. “Already 150 jobs have been supported across Aitkenvale, Southport and Stafford, with workers helping to build much needed shelter for 32 households in need of housing support. “The Queensland Government is proud to be supporting housing projects that will provide housing for Queenslanders in most need but also employment for our tradies in every part of Queensland.”

Building A Strong Reputation National Precast began when a small group of New South Wales based precast manufacturers recognised the need for a national industry body. According to National Precast CEO Sarah Bachmann, the last 25 years have seen the organisation build a strong reputation for delivering outcomes. “What we have all managed to achieve over 25 wonderful years is impressive, and shows what can be done when there is a united effort” she says.

when it comes to industry practices, while ensuring a level playing field is maintained across supply chains. “As the peak body for the precast concrete industry in Australia we have built a strong reputation, having forged relationships with government, as well as allied industry and professional bodies across the country. They now come to us seeking input, which is a far cry from where we began”. Technically, the Association represents its members and the precast industry in over 20 forums, having input on Australian Standards, codes of practice and specifications. It is in regular dialogue with the likes of Standards Australia, Austroads, state roads’ authorities, Safe Work Australia, state workers’ compensation authorities, sustainability organisations and the like.

Capable of withstanding a one in 100 year rainfall event, a permeable earth retention system manufactured by National Precast member Rocla re-lines the 220 metre open Jaye Street Drain drainage channel in Cairns. The channel has been built within the existing footprint, thereby requiring no extra excavation and having little or no effect on the existing vegetation and infrastructure.

Providing vital infrastructure for the next 100 years to Melbourne’s Alphington, the North Yarra Sewer has been upgraded. Precast concrete segmental shafts and lined trenchless jacking pipes manufactured by Humes were easy and safer to install than an insitu alternative and offer a minimum-maintenance solution. As Australia’s first government-accredited Buddhist College in Wollongong, NSW, the $40 million Nan Tien Institute has been hailed an architectural and engineering milestone that pushes the boundaries of construction. 169 curved precast walls inspired by a lotus flower create four separate pods around a central public space. They feature a timber pattern and were manufactured by SA Precast in custom moulds. The result of outstanding collaboration and teamwork speaks for itself with the $850 million luxury Oracle Apartments on the Gold Coast. Twin 52 and 42 storey towers together with a four storey podium feature 1,540 kidney-shaped curved façade panels manufactured by Precast Concrete Products, as well as 24 intricate GRC screen panels and 26 distinctive GRC fins manufactured by Asurco Contracting.

Construction Engineering Australia • Oct/Nov 2016

What is GRC? Glass Reinforced Concrete, otherwise known as GRC, is factory-made precast concrete which uses glass fibres as reinforcement, instead of steel reinforcement that is used in conventional precast. Why use GRC? GRC is known for its light weight, strength, durability, fire safety, sustainability fast erection times and excellent acoustic properties. It is an incredibly versatile product that can be moulded into any shape, with any pattern or colour. Where is GRC used? GRC has been around in Australia for 40 years and has been used in a wide range of applications such as building facades, arches, tunnels, pits, monuments, sound barriers, planters and furniture.

PRECAST TECHNOLOGY

CARRYING CONCRETE WITH COMBILIFT Straddle carriers and mobile gantries for the cost effective and efficient handling of precast concrete

This custom-designed Combilift remote-controlled unit offers a fast, safe and efficient method of lifting and moving large precast concrete elements. Combilift units are available with or without cab, in both driver and remotely operated designs.

Combilift Ltd is the specialist manufacturer of multidirectional forklifts as well as a wide range of other innovative solutions for the safe, space saving and productive handling of long and awkward loads, pallets, containers, and extremely oversized loads. From its base in Monaghan, Ireland, the company exports to over 75 countries and has sold more than 30,000 units since it was established in 1998. The extraordinary growth of Combilift has been unparallelled in its industry sector and the company has invested 40 m Euro - around 60 m AUD - in its new, purpose built 46,000m² manufacturing facility and global HQ, which will be up and running by the first quarter of 2017. This expansion will enable Combilift to proceed with its plan to double its current €150 million turnover in the next five years. When it comes to handling potentially problematic and extreme loads such as those in the precast sector, two Combilift model ranges – the Combi-SC Straddle Carrier and the Combi-MG Mobile Gantry, are proving to be particularly beneficial. They are a much more efficient option compared to heavy handling forklifts, reach trucks, mobile cranes or fixed cranes and have recently been deployed in major projects: for example in the construction of the New Perth Stadium, where they have operated both on site and in precasting yards. They have also been used in infrastructure projects such as the Pacific 30

Construction Engineering Australia • Oct/Nov 2016

Highway upgrade in New South Wales and the Roy Hill Mine Rail. The Combi-SC range was introduced in 2010 as a cost effective solution for container handling. It quickly became apparent however that its design and features made it ideal for the requirements of any operation which manufactures and/or handles oversized loads and needs to do so safely, whilst ensuring optimum space utilisation in and around the facilities. Simple and straightforward design incorporating standard, easily available components makes it a very reliable workhorse which is easy and economical to service: this is a key benefit in the concrete sector which is traditionally a harsh, tough user of equipment. A major advantage of the Combi-SC is its light unladen weight which can be as low as 17t depending on the model, making it extremely fuel efficient. In addition, the even load distribution and large tyres significantly reduce ground pressure and allow operation on compacted surfaces, avoiding costly investments in ground reinforcement. The 3-Wheel concept, with two wheel hydrostatic drive and synchronised hydraulic steering, makes for a manoeuvrable machine with a very small turning circle, providing customers with complete independence on site and when loading and offloading trucks and semi-trailers. In addition, the fully automated operation of functions from within the 360º

visibility cab reduces the risk of manual strain and protects operators from the elements. The Combi-MG is remote controlled with all wheel steer and comes with six steering functions as standard. Thanks to multidirectional capability with carousel function it offers superb manoeuvrability both indoors and out. As wheels are positioned at the front and back of the unit rather than at the side, the width of each machine need only be as wide as the loads it moves. Combilift is well known for its ability to customise its products according to individual requirements and the Combi-SCs and CombiMGs are no exception. With the option of LP Gas or diesel power and a wide array of options, attachments and lift capacities to choose from, customers can be assured that their model is tailor made to their specific application. “Combilift products enjoy a strong presence in the Australian market and these two particular models have certainly made their mark on the precast sector,” said Chris Walker, General Manager of Combilift Australia. “We foresee a high level of market demand for them due to their ability to enhance productivity and health and safety procedures as well as the excellent ROI that they offer.” For further information, contact Combilift Australia, T: 1300 552 422 or visit: www.combilift.com

PRECAST TECHNOLOGY

LIFTING PRECAST CONCRETE ELEMENTS Meeting New Standards In today`s fast paced construction industry, it is increasingly difficult to keep abreast of frequent regulatory developments in Construction Codes and Standards. At the same time, in a highly litigious World, we are constantly reminded of our responsibilities, and of the risks associated with non-compliance. This is of particular importance when such regulatory changes involve safety critical operations. A prime example being the recent publication of a new Australian Standard that outlines mandatory requirements relevant to the lifting of precast concrete elements and to the lifting systems associated with the lifting of precast concrete elements. In September 2015 Standards Australia published, in parts, Australian Standard AS 3850: 2015 “Prefabricated concrete elements” which outlines mandatory requirements ranging from design through to the incorporation into the final structure of prefabricated concrete wall panels, columns, beams, flooring and façade elements used in building construction. The reader should note that this Standard superseded Australian Standard AS 3850: 2003 which was previously limited in applicability to Tilt-up concrete construction. AS 3850: 2015 Part 1 – General requirements, outlines the mandatory requirements for the materials, components and equipment used in the manufacture of prefabricated concrete elements, and Part 2 – Building construction, outlines the requirements for planning, 32

Construction Engineering Australia • Oct/Nov 2016

construction, design, casting, transportation, erection and incorporation into the final structure of prefabricated concrete elements in building construction. Significantly, the revised Standard places tight controls on the manufacturers of Lifting Systems, their performance claims and the methodology by which Working Load Limits are derived. It is a mandatory requirement of AS 3850.1:2105 that the performance of all Lifting systems are validated by the test method prescribed in Appendix A and derivations made from such testing are in accordance with the calculation method prescribed in Appendix B (Concrete Capacity Design Method). This includes lifting devices, lifting inserts, their performance in concrete and as a complete lifting system. It is important to note that in relation to lifting devices and lifting inserts any claims made by the manufacturer in respect of compliance to the superseded Standard AS 3850:2003 will not necessarily translate as a claim of compliance with the current Standard AS 3850:2015. It is important that users assure themselves that the lifting clutches and inserts used comply to the current Standard (AS 3850:2015) and it is the responsibility of the manufacturer to provide the user with verification of such compliance.

Ferguson, was deemed essential to provide up-to-date guidance on formwork design that fulfils the requirements of AS 3610.1 2010 and AS 3610 1995. The Handbook expands on the content of the Standards that pertain to formwork design and documentation and also provides background information. The design methods set out in the Handbook comply with the requirements and methods, as well as, where possible, the notation set out in the latest Australian material and design Standards. In fact throughout the document information has been adapted to comply with Australian Standards and practice. The primary focus of the Handbook is to provide guidance in areas of formwork design critical to safety. Accordingly, the scope of the Handbook has been limited to addressing: design and construction procedures; general design requirements; design actions, combinations and their application to side and soffit formwork; falsework design; and stripping and multi-storey shoring. Information is also provided on identifying defects in the surface finish of formed concrete.

FORMWORK DESIGN It is commonly known that during construction, formwork supports and acts as a mould for wet concrete. Often it is referred to as "temporary works" although some formwork, or part thereof, may remain part of the permanent structure. The term "formwork" describes both the forms directly in contact with concrete and a supporting structure of braces and form ties, and where appropriate, falsework. Formwork is important because it has a major impact on the quality, cost and time to build concrete structures. Critically, sound design and construction of formwork is essential to ensure safety during construction. In Australia, requirements for the design and construction of formwork are set out in AS 3610 1995 Formwork for concrete (SA 1995), including Amendment No 1 (January 2003), and AS 3610.1 2010 Formwork for concrete Part 1: Documentation and surface finish (SA 2010). AS 3610.1 2010 supersedes only part of AS 3610 1995, specifically: only Sections 2 and 3, Clause 4.7 and Section 5 of AS 3610 1995. Until AS 3610.2 is published the requirements for formwork design and testing set out AS 3610 1995 Sections 4 (except for Clause 4.7) and Appendix A still apply. Since they first appeared in AS 3610 1990, only minor amendments have been made to the requirements for design and testing set out in AS 3610 1995. Some requirements are now out-of-date. Recently the Concrete Institute of Australia published the long awaited Recommended Practice Z36 Formwork Handbook. The compilation of this handbook by the Technical Committee for Formwork, driven and led by experienced formwork designer Stephen 38

In addition to updating the content provided in Standards, the Handbook introduces concepts not covered in the codes including: • The introduction of the concept of a “formwork coordinator” who is responsible to manage and coordinate formwork design and construction. • Setting out roles and responsibilities of all those involved in formwork design and construction. • An outline of general formwork design requirements that must be satisfied. • Changes and new concepts related to types, sizes and application of loads directly related to formwork. • An introduction to the design of side formwork and bracing side formwork, and to the design of soffit formwork. • The fundamental aspects related to the design of formwork falsework. • Guidance on assessing formwork importance based on consequence of failure. The Formwork Handbook is intended to be a useful reference for practicing and student engineers, project designers, construction contractors, formwork contractors, formwork designers, formwork suppliers, formwork checkers and formwork inspectors.

CONCRETE PILING Concrete piles are frequently required as the primary foundation support for a wide range of buildings, bridges, towers, dams, and other large structures. Typically they are needed when there is a weak layer of soil at the surface that cannot support the weight of a structure, or when a structure has very high concentrated loads. As the basis to any large or difficult construction, the design of concrete pile foundations is a vitally important part of any project. Australia is privileged to have one of the world’s leading experts on pile foundations, Professor Harry Poulos, who has lent his expertise to students, designers, and practitioners throughout the country for a number of years. The Concrete Institute of Australia is fortunate to have Professor Poulos available in October and November to present around the country on Pile Foundations – Analysis and Design. This course aims to provide up-todate information on modern techniques of analysis and design of pile foundations. It will address a range of practical issues involving axial and lateral loading on piles, the effects of ground movements on piles and pile groups, and pile load testing. Emphasis will be placed on soundly-based methods which can be implemented without necessarily using complex software. In many cases, design charts will be presented so that rapid initial estimates of pile performance can be made by the designer. Considerable attention will be devoted to the assessment of geotechnical design parameters which are required for the analyses, and correlations or methods of testing piles and pile elements to obtain these parameters. The course also includes presentations and case studies on local projects from Wagstaff Piling and Piletest. These case studies, which will include a special focus on work being conducted on the CityLink Tulla project in Melbourne and the New Perth Stadium in WA, bring a practical element to the theory. Given the experience of these two organisations it will cover the many structures and conditions that piling is required for. There may still be time to register for the event in a city near you. Visit www.concreteinstitute.com.au/Piling for more details.

Professor Harry Poulos started his professional geotechnical career as an academic at the University of Sydney in 1965 and became involved in research into the analysis and design of pile foundations. In 1989, he joined consulting firm, Coffey International, which he continues to be associated with to the present day. Professor Harry Poulos Harry became involved in the design of foundations for very tall buildings in 1994 through his involvement with the iconic Burj Al Arab hotel in Dubai. Subsequently, he has participated in the design of foundations for a number of other projects in the Middle East and Asia, including the Emirates The Burj Al twin towers in Dubai, the Nakheel Arab hotel tower in Dubai, Dubai Towers in in Dubai Qatar, the Entisar Tower in Dubai, the Diamond Tower in Jeddah, Saudi Arabia, the Incheon 151 Tower in South Korea, the Taipei 101 tower in Taiwan, and the International Finance Centre in Hong Kong.

PRODUCT FOCUS Tsurumi’s KTZ series. Dewatering pumps for construction sites, quarries and batch plants.

CONCRETE COST CUTTER The evolution of sand, gravel, cement and water into concrete, as the Romans discovered, is one of the key foundations of civilisation. Without it we would be living in slab huts or freestone crofters. It may be a gift of nature, but concrete batch plant operators know that cost control has direct impact on profitability! Brand and reliability play a big part but the ability to deliver concrete on time, and at the right price is critical for survival in the industry. The market has got use to a very high standard of product produced by an industry that is famous for its professionalism.

IT STARTS IN THE QUARRY The story starts in the quarry where the raw material for the product has its origins. Australian Pump represents Tsurumi the world’s biggest and leading manufacturer of electro submersible pumps. With its origins in Osaka, they played a key role in producing pumps for the rebuilding of Japan after the Second World War. Since then, Tsurumi have branched out with plants and offices around the world and become market leaders in electro submersible dewatering and drainage pumps. The company, Tsurumi pump, started out with a concept of producing products that are suitable for the toughest, most abrasive and difficult dewatering or drainage applications. The result of seventy years of R & D and application experience is the range offered in Australia to the industry by Aussie Pumps. The range now includes sand pumps with capacities up to 13,000 litres per minute, dredger pumps, high head dewatering pumps and even portable single phase units. 40

Construction Engineering Australia • Oct/Nov 2016

“Our latest offering to the market is a single phase portable slurry pump with integrated agitator. That pump can be an invaluable tool in a batch plant with an emergency situation and concrete to deliver,” said Aussie Pumps product manager Neil Bennett. Dewatering pumps for quarries and sand pits extend from low head sand or slurry pumps all the way through to high head dewatering products. The submersible pumps use insulated motors as big as 110 kilowatt and deliver heads as high as 200 metres. The pumps are used in a wide range of quarry applications, keeping them operational or bringing them back into operation after heavy rainfall in the shortest possible time. The electro submersibles provide a number of significant advantages over their equivalent diesel drive pumps. They can operate autonomously 24/7 without needing to be refuelled, have their oil changed regularly or fuel filter checked. Tsurumi’s submersible sand and dredger pumps make an ideal solution for quarry or sandpit dewatering. Tsurumi shines in this application with an engineered product range that is built around feedback from users. Tsurumi’s engineers tackled the problem of motor failure through water ingress by eliminating the problem of water wicking through a broken or damaged cable into the motor. They achieved this with a unique anti-wicking cable entry at the cable end. In the seal department of the pump, their double stainless steel silicone carbide mechanical seal protected by its unique design, operates in an oil bath with patented “oil lifter” designed to keep the seals continually lubricated. Pictured below (clockwise from left): The KTV series are a compact, portable, three phase dewatering pumps; Neil Bennett with the HSD single phase portable slurry pump with integrated agitator; The KRS are heavy duty dewatering pumps, that offer reliability, ruggedness and durability.

Powering a Sustainable Future Above (from left): KRS Slurry pump handles solids to 30mm, ideal for quarry or batch plant applications; Aussies batch plant selector guide makes it easy to select the right pump for each plant function.

Tsurumi’s impellers are not only designed for maximum efficiency but made from the highest quality high chrome iron. The pump bodies are either of cast iron or, in some of the more recent models, cast 316 stainless steel.

BATCH PLANT ACTION If it’s important to have reliability for dewatering at the quarry or sandpit, then it’s even more so at the plant. Batch plants that can’t pump water are unable to deliver concrete. Australian Pump have analysed each function in the batch plant and selected the correct pump in terms of construction, model and application for that particular function. For example, their new slump stand pump, a high head heavy duty dewatering submersible, has enough pressure to act as a lift pump and a wash down pump as well. As a submersible, the pump is out of sight, more compact and far less troublesome than surface mounted equivalents.

PLANT PUMP SELECTION CHART Australian Pump are the first company to bring out a pump selection chart that makes selecting the right pump for each plant function easy. “We have found pumps in batch plants all over the country that were never designed for the application they are operating in,” said Aussie Pumps’ Product Manager, Neil Bennett. “We have even pulled sewage cutter pumps out of batch plants where for obvious reasons where they have been misapplied. You can imagine the short life and high cost of a misapplication like that,” he said. The chart makes it easy for the batch plant manager to make a selection and source products promptly as required.

AUSSIE’S BATCH PLANT SUPPORT PROGRAM Australian Pump developed a batch plant support program that has enabled batch plant operators to cut costs. “Getting the right product on time, from a local supplier means plants don’t have to compromise by putting in a product that isn’t going to do the job,” said Bennett. The time taken to get a replacement pump can be critical. Australian Pump are appointing depots around the country to stock the most common models for immediate delivery. “The temptation to buy an incorrect pump in an emergency can be eliminated and that is one major risk averted,” said Bennett. Australian Pump’s batch plant support depot program is locating stocking points across the country that can offer fast delivery of the world’s best batch plant pump. "We believe Tsurumi’s KTZ series represent the most reliable product of their kind in the world and the three year warranty offered by the company justifies their confidence. Users, not only in Australia and south east Asia, but also in Europe have standardised on this excellent product range," he added.

A Video link of the Minister's full speech is available at: www.ipwea.org/newsouthwales/home IPWEA NSW Chief Executive Officer John Roydhouse said: "The awards are an integral part of assisting public works professionals to build better communities. Showcasing excellence, new techniques and innovation, the prestigious awards provide peer recognition and knowledge sharing." Rockdale City Council won the COMPLETE Multi-Disciplinary Project Management Award for the Beautiful Rockdale Library. Library

Tamworth Regional Playground

Services commenced in the Rockdale Council area in 1955 with a mobile trailer and developed with the establishment of a main library in the Rockdale Town Hall in 1982. This facility quickly became outdated and could no longer comply with the State Library of NSW. In June, 2014 Council appointed the company Kane Constructions for the Design and Construction of a new library in the amount of $14M. As part of this contract Brewster Hjorth Architects prepared the construction documentation to implement the original design, whilst CK Design international remained the designer and documenter for all interiors.

Design and/or Construction of a Local Government/Public Works Project Category 1B was the largest category with 23 submissions received. The well deserving winner was the newly formed Central Coast Council for the Wyong CBD Drainage Upgrade. Following the April 2007 floods, Council set about rectifying the drainage issues by designing a new drainage system from the top of the commercial area catchment to its lowest point. Due to the complexity of the design and the unknowns that would be encountered particularly in regard to underground services, Council chose to carry out the design in-house, and for similar reasons to complete the design using its own construction team. City of Canada Bay won the award for Environmental Enhancement Project or Initiative including Recovering, Recycling and Reusing with their Water for Our Community Project. The Water for Our Community project is a stormwater harvesting scheme that provides for the uncontrolled irrigation of 15 sports fields and two golf courses in the City of Canada Bay. The David Abbott Award for Under-35s was awarded to Will Barton from Junee Shire

Council. Will is a regional leader in developing the professionalism of the Public Works sector, at all times he shows commitment to Engineering Will Barton principals and values yet tempers this with a subdued respect for all points of view within a discussion. The award for Public Works Leader of the Year (partnered by Boral) went to Mark Roebuck of Wollongong Shire Council. Mark has chaired the local Mark Roebuck Illawarra group for many years and is always trying to encourage verbal interactions between all participants, especially younger engineers and cadets.

He has worked with Wingecarribee Shire Council for 4 years as Manager Operations and with NSW Public Works as a Regional Projects Coordinator working with most councils in South Eastern New South Wales. Since starting back at Wollongong he has been actively mentoring the civil engineering cadets, encouraging networking and attendance at the Regional forums and CIVENEX. “Public works engineering is not just about the projects. IPWEA seeks to recognise the people behind the projects, their leadership and contribution to our communities. Our leadership winners will now represent NSW in the 2017 International Public Works Leader of the Year Award to be announced in Perth in August 2017” Mr Roydhouse said. Albury City Council have also been recognised with the Special Award – The Novelty Award. They were recognised for their Albury Botanical Garden, Castle Toilet which filled the need for toilet facilities for the Children’s Garden at Albury Botanic Gardens. The existing play space contained trails to explore and a wonderful array of items for children to discover. Highlights include a life-

CONSTRUCTION TECHNOLOGY

THREE TOP TECH TOOLS TO BOOST PRODUCTIVITY FOR ARCHITECTS, ENGINEERS AND CONSTRUCTION WORKERS By Angelo Wolfram, Enterprise Sales Manager, Newforma

To those of us familiar with the architecture, engineering and construction (AEC) sector, the conclusion of McKinsey’s recent Imagining Construction’s Digital Future report came as no surprise – resisting digitisation is simply no longer an option. Construction has notoriously been one of the least digitised professions worldwide, but surprisingly the report found only hunters and those in the agriculture sector shunned technology as steadfastly, with construction companies on average investing just 1 per cent of revenues into information technology. While there are still pockets of Australia’s construction industry which rely on paperbased process, the mobile phone, laptop and file server have quickly become the new tools of the trade for all levels of workers through the design, planning, build and management phase of a project. In fact, the average amount of digital data generated by a typical large design and construction project today is 6.5 terabytes - 65 times greater than the 100 gigabyte average for a similar project just ten years ago, according to Newforma data. To stay on top of this data explosion, there’s still an overwhelming need for the AEC sector to invest in digitisation in order to ‘fix the basics’, such as project planning, quality control, contract management and supply chain practices. With the global construction industry booming (the McKinsey report estimates a global spend of $57 trillion on infrastructure 46

Construction Engineering Australia • October 2016

by 2030 to keep up with global GDP growth), there is no shortage of technology companies out there seeking to help AEC workers do more with less. Too often though it’s left up to individual project managers or pockets of teams within an organisation to seek out technology solutions to help streamline processes and allow them to focus more energy into getting the job done. Allowing employees or teams to independently manage information in their own silos can result in serious issues when it comes to accountability and visibility. A lack of process can also expose a business to regulatory and legal consequences. Now is the time for AEC leaders to invest in company-wide digital processes that bring sophistication and efficiency to their business and the entire sector. But when faced with so many options, how do you separate the wheat from the chaff? Here are my three AEC software picks to get you started:

1. PRODUCTION PLANNING: LEAN PLANNER Lean methodology has been used in manufacturing for decades, but it’s growing in popularity in the AEC space to help diverse teams work on complex projects and meet tight deadlines. Lean Planner is based on ‘lean principles’ specific to the AEC industry, which encourage teams to work with maximum efficiency. This approach, which is growing in popularity, acknowledges that you and your

team are experts in your field but also that you’re incredibly busy, and so need solutions which work on an individual and team level. One of Lean Planner’s attributes is that it replicates the look and feel of sticky notes, but can be worked on collaboratively, packing them with more information and making reporting easy and transparent. It also means you and your colleagues can easily dig down into project plans to find the latest reliable and authorized information to inform your decisions. Most importantly, Lean Planner takes the manual work out of identifying potential setbacks and constraints you and your team might face. This gives you time to address the issues and capitalise on opportunities before they pass you by.

2. BUILDING INFORMATION MODELLING: REVIT Revit is designed to support Building Information Modelling (BIM) workflows, which is revolutionising how infrastructure is planned, designed and built. Using BIM workflows from conception to construction, Revit helps you model designs precisely, optimise your performance and collaborate more easily with all teams working on the project. Any revisions or alterations to information are updated across the project, from model views and drawing sheets to schedules, sections and plans. It’s designed to keep things simple, and its focus on efficiency and accuracy is second to none.

CONSTRUCTION TECHNOLOGY

The technology is non-invasive to existing processes, workflows, and data formats, and has proven successful with companies across the globe. Project teams have shared more than 6,000 terabytes of data, including over 5 billion documents spanning more than two million projects. Industry leaders need to think boldly when it comes to piloting new digital technologies in their workplaces. It’s time we embrace digital change and lead the way in transforming the way the AEC sector operates.

3. INFORMATION MANAGEMENT: NEWFORMA Newforma’s Project Information Management platform helps architects, engineers and builders leverage all the data relevant to project success, whether it’s in the cloud, on a mobile device or behind the firewall. The technology breaks down data silos and enables secure, real-time access to the data teams need, like drawings, plans and models. It enables teams to collaborate more effectively, make more informed decisions, and derive better project intelligence.

PROJECT BRIEF

THE NATIONAL GALLERY SINGAPORE After a decade in the making, with extensive new works and refitting of existing spaces, the National Gallery Singapore, now fully complete now proudly displays the world’s largest public collection of modern Southeast Asian art. It reopened and refurbished and joined two existing major buildings that are significant structures in Singapore’s history, and also has the purpose of exposing the world to modern Southeast Asian art. The outstanding feature of the new external works consists of an expansive canopy supported by interesting steel tree-like columns to link the former Supreme Court Building and City Hall at the roof level. The design incorporates a wide extended staircase linking the basement to the upper levels, making use of solar energy to provide electricity. The connection, designed by French Architects Studio Milou, uses metal mesh under a glass canopy to temper Singapore’s equatorial climate. The sculptural use of this enclosure creates a delightful outdoor space offsetting the formal enclosed interior rooms now converted to galleries. The design preserves the integrity of both of the buildings’ history and structure while giving it a contemporary feel through two floating footbridges that connect the buildings, and a massive rooftop garden. The glass and steel roof held in place by supports that resemble tree branches covers the two structures. The 69,0000 square metres that make up the museum make it not only Singapore’s largest museum, but also its largest space dedicated to visual arts. City Hall the former Supreme Court buildings are national monuments and have played a significant role in Singapore's history. The city hall also preserves the country’s history with by keeping intact the room where Japan surrendered to the British, and where Singapore’s first prime minister and first president were sworn in. The buildings face an open field known as the Padang, which is a Malay word meaning "flat field". Through link bridges and a new basement level, the design for the new Gallery integrates the City Hall and former Supreme Court buildings, combining both old and new architecture. The architecture of the former Supreme Court building is in harmony with that of its neighbour, City Hall. The general layout of the Supreme Court building exemplifies British colonial architecture, comprising four 48

blocks of offices and courtrooms surrounding a central rotunda with a dome that was originally used to house a circular law library. It was to be the last classical building to be built in Singapore, displaying its Corinthian and Ionic columns, sculptures and relief panels. Consisting of modern and contemporary art, National Gallery Singapore focuses on displaying Singapore and Southeast Asian art from the 19th century to present day.

BUILDING AN URBAN OASIS

Sensory gardens specifically designed to provide a little 'peace of mind' In our fast-paced, increasingly busy and rapidly expanding innercity and urban areas, getting a little 'peace of mind' can be far from easy. Indeed, for many people, even the task of actually getting to somewhere that is relaxing and tranquil can often cause more stress than it's worth. Now, while that in itself may seem to be (to coin another commonlyused phrase) somewhat of a 'first world problem', the inability to find a little tranquillity and 'peace of mind' in an increasingly busy world can, and does, have extremely serious consequences. The increased stress levels associated with constant activity and/or an inability to relax and refocus can have a serious detrimental effect on both physical and mental well-being. So much so, in fact, that many leading mental health researchers are now considering 'mindfulness' and mental relaxation to be one of the most important factors in improving mental health. With that in mind, Sydney-based company Aussie Outdoor Design has developed a range of 'Sensory Garden' solutions that provide an mini 'urban oasis' where visitors can relax and take a little time out from the busy world. Jason Day, Business Development Manager with Aussie Outdoor Design, explained: "Unfortunately, with open space being at such a high premium, and traffic and transport being the way it is, for many people living and working in densely populated areas, even getting to somewhere that's relaxing can present a massive challenge." "That's why we've developed the ELEMENTS Natural Environments gardens as a fully-scalable solution that can be established almost anywhere." "Even if there's only a small area available, we can design and deliver a fully-accessible sensory garden with an array of elements that will provide an attractive relaxation and passive recreation area to suit all ages and abilities," he added.

ACA CORROSION FEATURE

Battling building envelope corrosion Concrete is usually the foundation of a good building and efficient management of the effects of concrete corrosion can extend the life of a building. However, concrete is not the only part of a structure that is threatened by corrosion. On any building, both the cladding and the fasteners holding it in place are exposed to varying degrees of corrosion. Less obvious parts that corrode are the polymers used as sealants and the protective coatings applied to other materials. Corrosion continues to impose a massive cost on industry. This has been estimated, in a recent report issued by NACE (USA) to be more than three per cent - or multiple billions of dollars - of global GDP each year. One cost that may not be obvious is unbudgeted capital expenditure to replace damaged frames, walls and façades resulting from the “leaky building syndrome.” A “leaky building” is one that, as a result of defective design, materials, or construction - usually a combination of all three - allows water to enter through 52

the external building envelope which then causes decay and damage to the internal structure of the building. The situation arose from a combination of factors in the late 1990s and early 2000s that saw the construction of a large number of buildings using substandard materials that were vulnerable to moisture ingress. “Leaky building syndrome has become a serious problem in New Zealand,” stated Les Boulton, Principal Consultant of Les Boulton and Associates in Auckland. “It is becoming a global issue for many governments as there have now been court cases in New Zealand, Australia and Canada where developers and manufacturers are being sued.” There have been many contributing factors to the problem of leaky buildings, including poor quality metal flashings which allow water to get behind the façade of a building and corrode materials such as the building framework and cladding fastenings. In some cases, bare steel has been used for internal structural elements and left exposed to harsh coastal climates.

It is not only reinforced concrete in a building or structure that is impacted by corrosion. A broad definition of corrosion is 'the degradation of a material through interaction with its environment' which means that any part of a building is prone to some type of corrosion over time and at varying rates. The Australasian Corrosion Association (ACA) is an organisation that works with industry and academia to provide an extensive knowledge base of research that supports best practice in corrosion management for situations such as 'leaky buildings'. This collaboration helps ensure all impacts of corrosion are responsibly managed, the environment protected, public safety enhanced and economies improved. Polymers are used extensively in the construction industry, including as seals around windows and doors; guttering and downpipes, and corrugated polycarbonate panelling. These are all affected by sunlight (UV radiation), moisture and heat. In addition to structural use, polymers are also

often used as sealants over other materials, including concrete. UV radiation interacts with a polymer at the molecular level where the UV has the right energy to modify chemical bonds. The majority of testing of polymers and other construction materials has been carried out in European countries and the climatic conditions of the Northern hemisphere. Research by organisations and government bodies - such as private consulting companies and BRANZ - has shown that at equivalent latitudes, New Zealand and Australia experience larger amounts and more intense UV radiation. Durability appraisals by BRANZ have shown there is even a noticeable difference in results for the same material when tested in the north and south of New Zealand. Even if stored in a dark cupboard, polymers still interact with their environment. When used as an additive to materials such as concrete, thermal and wet/dry cycles can leach out chemical binding agents. According to Boulton, “leaky buildings” are not unique to New Zealand, but the geography and climate of particular sections of that country seem to exacerbate the problem. In the past 10 years, corrosion on fixings of aluminium composite panels (ACPs) had caused a range of failures in commercial buildings clad using this material, resulting in panels becoming loose and allowing water to enter the building envelope.

“However, because it is not seen, building owners have been slow to recognise the problem,” Boulton said. “Asset owners need to be proactive about checking their buildings and cladding to ensure there is no water ingress.” Inspection reports have shown that 'leaky buildings' have been built with monolithic cladding systems which provided little or no margin for error if moisture ever did penetrate behind the cladding and into the building envelope. Usually, the untreated, kiln-dried framing timber which had been approved by the now defunct Building Industry Authority for use in construction was particularly susceptible to any moisture ingress. By the time an asset owner realised that there was a problem it was already too late to fix it without rebuilding significant parts of the structure of the building. Another contributing factor was that for many years, developers had no incentive to pay for the best design of their buildings, nor the appropriate level of supervision of construction to ensure the buildings were constructed properly. The NZ Building Code (NZBC) Clause B2, Durability, requires that all building components are fit for purpose and provide a service life as stated in the NZBC. Durability appraisals of building products are required before a new product is deemed to be fit for installation in a new building. This requires an independent assessment of the building product, system design, material corrosion resistance, and

installation practices. It is also important that the testing also reflects the geographic environment of where the building materials will be used. “Thorough appraisals give the construction industry and asset owners confidence that the new products have been subjected to a robust technical examination by experts before the product is released into the market,” stated Boulton “Some failures in the ongoing leaky building crisis have been caused by water ingress behind inadequately designed or installed cladding systems which resulted in corrosion of hidden metal fixings.” Boulton added. When plastics eventually become brittle due to UV exposure, they no longer afford the protection for which they were designed. There have been instances of objects falling through polycarbonate canopies and injuring people below. While the most visible degradation effect on polymers is an aesthetic one where a grey-white powdery substance forms on the surface, there are many other less obvious effects such as PVC guttering and downpipes developing cracks and leaks that could allow water to get inside the building envelope.

Corrosion in concrete construction Billions of dollars are invested in reinforced concrete buildings and structures around the world. Corrosion of the reinforcing steel in concrete is a global problem that causes a range of economic, aesthetic and utilisation issues. However, if corrosion effects are considered in the design phase and the right decisions made prior to construction, buildings can be built to last and protected for as long as possible. Corrosion in all its forms has been estimated to cost government and industry more than three per cent - or multiple billions of dollars - of global GDP each year. Effective corrosion management strategies can help reduce this cost. The corrosion of steel in concrete is accelerated in harsh environments especially coastal, tropical or desert - where high salt levels or extreme temperatures can accelerate the rate of decay. Usually, the most exposed elements deteriorate first but because the active corrosion may take 5 to 15 years to initiate cracks in the concrete, much of the actual corroded reinforcement is not visible. As the degradation of the steel and weakening of the concrete occurs from the inside and may not be seen for many years, it is often referred to as 'concrete cancer'. The alkaline (high pH) conditions in concrete forms a passive film on the surface of the steel reinforcing rods, thus preventing or minimising corrosion. Reduction of the pH caused by “Carbonation” or ingress of chloride (salt) causes the passive film to degrade, allowing the reinforcement to corrode in the presence of oxygen and moisture. 54

Construction Engineering Australia • Oct/Nov 2016

The traditional method of concrete repair is to remove the cracked and spalling concrete to a depth of 20-30mm behind the reinforcing bars to fully expose the rusted material and remove the contaminated concrete from the steel. All the corroded material is then removed and the steel treated or replaced, after which specialist repair concrete mortars are applied and the surface made good. A modern development is for the repair mortars to be polymer modified to improve adhesion and resist further ingress of contaminants. Coatings are commonly used in combination with patch repairs to reduce further entry of carbonation or chlorides. These “patch repairs” that remove the contaminated concrete from the deteriorating sections often do not address this hidden corrosion and result in accelerated deterioration to the surrounding areas, commonly failing again within 3-5 years. The main alternative to patch repair is Cathodic Protection (CP) which is where a small, permanent current is passed through the concrete to the reinforcement in order to virtually stop the corrosion of the steel. CP minimises the amount of concrete that needs to be removed, with only the spalled and delaminated concrete required to be repaired. Once installed, the ongoing corrosion can be controlled for the long term, eliminating future spalling and deterioration even in severely chloride or carbonation contaminated concrete. Prevention and remediation of concrete corrosion will feature in several seminars during the Australasian Corrosion

Association (ACA)'s Corrosion & Prevention 2016 conference in Auckland in November. The latest advances in corrosion management processes and technology will be presented as part of the various technical streams during C&P2016. Other topics covered at the conference include advances in sensing & monitoring; asset management; cathodic protection; concrete corrosion and repair; corrosion mechanisms, modelling and prediction; materials selection and design, and protective coatings.
