NO CONSEQUENCES - NO REGRETS IS IT TIME FOR A ‘ZERO TOLERANCE’ TO GRAFFITI VANDALISM?

Dear Readers,

Considering the amount of time and resources that have been invested in graffiti prevention programs over recent years, I must admit to being more than just a little disappointed that graffiti vandalism is still so rampant throughout Australia.

Before I continue, I would like to clarify that I do understand the difference between graffiti vandalism and ‘street art’. Indeed, many innercity laneways (in Melbourne in particular) are adorned with ‘legally applied’ street art which is quite magnificent.

When I refer to ‘graffiti vandalism’, I am referring to illegally applied graffiti, particularly the mindless application of tags to practically any and/or every available surface – a crass and destructive act of vandalism by any measure.

Despite this, there are still some ‘cultural and social experts’ that will publicly espouse the value of self-expression gained through graffiti or (my personal favourite) the ‘valuable cultural capital’ that our cities could gain when graffiti gangs post photos of illegal graffiti activities and results on underground Internet sites.

Regardless of the fact that I couldn’t disagree more with these types of comments, I believe that the biggest issue is that any type of positive public commentary about graffiti vandalism can appear as ‘tacit approval’ for vandalism in all its forms.

Graffiti continues to be one of the most expensive and time-consuming public maintenance issues facing councils, householders, government authorities and private sector companies today. To suggest that we should somehow turn a ‘blind eye’ to graffiti vandalism is not only totally misguided, I believe it’s also highly irresponsible.

Even though a number of Australian councils have had significant success in reducing the incidence of graffiti (generally through costly, ongoing programs of rapid removal and repair), it’s a sad fact that even for these councils, removing graffiti and repairing graffitirelated damage continues to be an extremely expensive and onerous day-day-today battle.

Unfortunately, while we may have come a long way in some areas of graffiti management, I believe that one of the main reasons that we continue to suffer at the hands of graffiti vandals is that we, as a society, have failed to address some of the core issues surrounding graffiti. In addition to problems caused by easy access to spray paints, large-format permanent markers, and other graffiti ‘tools of choice’, we are yet to attach any real penalties to graffiti vandalism.

As such, I believe that graffiti vandalism continues to be viewed by many of the perpetrators as a simple case of ‘No Consequence - No Regrets’.

Furthermore, the sort of ‘mixed messages’ that are still being sent about graffiti – both

in relation to the cost and seriousness of the problem, and in terms of trying to attach artistic and/or cultural ‘value’ to graffiti – only serve to confuse the issue.

If you’ll excuse the pun, painting graffiti in a favourable light - for whatever reason - only runs a risk of encouraging more graffiti.

This doesn’t mean that we should throw our hands up in despair, believing nothing can be done or, worse still, take an apologist view and start making excuses for graffiti - quite the contrary.

I believe that the best way to address the problem is to remove that prestige. Rather than allowing graffiti vandals to view their individual ‘tags’ as something to be proud of, a ‘zero tolerance’ approach will see their tags become nothing more than a handy method of identifying and prosecuting repeat offenders.

Granted, widespread media campaigns and major policing operations carry a significant cost; however, when one considers the time, cost and resources currently allocated to removing graffiti and repairing the associated damage, the cost benefits of a ‘zero tolerance’ approach are easy to envisage.

Keeping Asbestos Out Of The Supply Chain Is Everyone’s Responsibility

A leading Australian expert on asbestos management, John Batty, Managing Director of EDP Consultants, part of the RSK Group, has called for community vigilance to stop asbestos at the source. This action will prevent it getting into the supply chain and ending up in mulch at public sites, potentially harming lives. John is also a member of the Asbestos Education Committee of the Australian National Asbestos Awareness Campaign and is a founding member and former president of the Asbestos and Hazardous Materials Consultants’ Association.

John says the community and businesses must be vigilant about how asbestos is being allowed to enter the supply chain through uncontrolled demolition and disposal practices ending up in mulch and potentially other recycled products.

John, who has 18 years’ experience in asbestos and hazardous materials management in Australia, the UK, Europe, and North Africa, points out that collective action can stop it at the source.

“When construction companies, builders, and mum-and-dad renovators demolish old structures, if an asbestos survey isn’t undertaken, there is a risk that the demolition may impact directly on unidentified asbestos-containing materials. This may inadvertently contaminate the building rubble with asbestos being mixed in with bricks, tiles, and timber. This can then lead to asbestos entering the recycling supply chain where items such as timber are being mulched up to be used as part of garden mulch.”

“As asbestos fragments may be small, there is a risk that they bypass the quality control system and end up in garden mulch."

"Even a small amount of asbestos presents a risk as the hazard is being reintroduced into the community,” says John.

“Homeowners, especially, need to be aware that one in three Australian homes contain some form of asbestos, especially those constructed before 1990. Australia had a true love affair with asbestos, with over 3,000 different products found to contain asbestos. That is why it is so important to identify the type and location of any asbestos-containing material within a property before any refurbishment or demolition work is undertaken.”

John also cautions homeowners to be asbestos aware, particularly when undertaking any maintenance on or cleaning asbestos-containing materials.

“EDP was recently called out to resolve an asbestos issue in Sydney where a homeowner engaged a handyperson to pressure wash their corrugated asbestos cement roof. This caused delamination of the cement, causing harmful asbestos fibres to spread throughout the area. It contaminated the house, garden, boundary fence, the neighbour’s house, and parked cars on the street. This posed a serious risk of asbestos exposure to not only the handyperson, but to the property owner, neighbours and public.”

“The neighbour called SafeWork NSW to complain, the property owner was hit with a clean-up notice and the handyperson did a runner. The final clean-up bill was more than $100,000, as all areas had to be cleaned. This included grass, garden beds and even trees having to be removed as asbestos waste,” says John.

John said there is a way forward through this crisis if we all treat asbestos with respect and ensure we follow current regulations to identify, remove and certify the removal of asbestos. This will ensure we keep asbestos out of the mulch supply chain and in a licensed landfill where it belongs.

Builders, homeowners, renovators, and tradesmen should engage a licensed asbestos assessor or competent person to undertake an intrusive and destructive asbestos assessment prior to any works to ensure asbestos is appropriately identified. It should be safely removed by a licensed asbestos removal contractor and be given a final clearance certification to note the area is safe to reoccupy and the remaining structure is safe to demolish.

“Don’t wait until the demolition has started. Asbestos is not a ‘do-it-yourself’ job.” John added.

“Similar to engaging an electrician or plumber, ensure you engage an asbestos professional at the start. That way, we’re limiting the community’s exposure and creating a safer environment for everyone.”

Master Plumbers Association Of NSW Criticises Federal MP's Call To Ban Gas Nationwide In New Developments

The Master Plumbers Association (MPA) of NSW strongly rebukes the recent statement by Wentworth Federal Teal MP Allegra Spender urging the federal Labor Government to implement a gas ban in new developments across Australia.

Nathaniel Smith, CEO of MPA NSW, denounced Spender's call as a “… ridiculous sign of virtue signalling” that threatens the nation's energy security and endangers vulnerable citizens, particularly during colder months of the year. Smith highlighted the essential role of Gas in mitigating power outages, as evidenced by recent incidents such as those in Victoria.

Contrary to Spender's assertions, Smith emphasised that household gas emissions contribute only one to two per cent of total emissions. He underscored the inadequacy of renewables to meet baseload power demands at present, asserting that they “just don't cut the mustard.”

Furthermore, Smith pointed out a glaring oversight in Spender's argument, noting that Jemena's Malabar (in her neighbouring electorate) plant produces 100% renewable gas known as biomethane. He urged Spender to conduct thorough research before making uninformed comments that could mislead the public. He also said, “The banning of Gas is a State Government matter, and recent bans from Councils would stand up in court.”

“In a time when reliable energy sources are crucial for our nation's welfare, misguided proposals like this only hinder progress,” remarked Smith. “We call upon policymakers to base their decisions on sound evidence and consider the broader implications on energy affordability, reliability, and sustainability.”

MPA NSW remains committed to advocating sensible energy policies prioritising Australians' needs while ensuring a sustainable future for future generations.

Finalists Announced For the 38th Annual Dulux Colour Awards

The finalists for the 38th annual Dulux Colour Awards have been announced by this year’s esteemed judging panel. A stunning 83 projects have been chosen from a record 527 entries, as judged by five design industry professionals from Australia and New Zealand.

As one of the region’s most prestigious awards programs, recognising the exceptional and innovative use of colour in the built environment, the Dulux Colour Awards attract an array of extraordinary projects. Up until 2024, awards have been given in seven categories: Commercial Interior – Public and Hospitality; Commercial Interior – Workplace and Retail; Commercial & Multi- Residential Exterior; Residential Interior; Single Residential Exterior; and, Student work for both Australia and New Zealand, with the coveted Australian and New Zealand Grand Prix awards, representing the pinnacle across all categories.

In an exciting expansion of the program, this year, an additional category has been added in recognition of the burgeoning area of Temporary or Installation Design.

“Expanding our program to award innovative colour use in non-permanent projects, such as exhibition spaces, installations and display suites, acknowledges the level of creativity that is being applied in this sector,” says Andrea Lucena-Orr, Dulux Colour and Communications Manager. “In fact, the sophistication of the projects in this category attests to the relevance of its inclusion. They are inspirational.”

Overall, the judges were impressed by the deeply considered, intelligent design pervading this year’s suite of finalists: hospitality venues and retail stores enticing customers through an understanding of colour psychology; primary schools with classrooms distinguished by

colour to aid learning and navigation; and, human-focused offices with masterful mood-setting palettes.

Having been part of the awards program team for many years, Lucenna-Orr has a unique overview of the shifting colour and design trends.

“This year, biophilia – the affinity of humans with the natural world – is a strong theme, with earthy colours playing a dominant role in interiors,” she says. “Olive greens, warm greys, muted taupes and dusky blues are coming into their own across several categories.”

Another stylistic direction is the bold use of saturated candy-like colours, clashing and contrasting against one another in projects of all types.

“It is an uplifting trend that shows a newfound optimism and confidence to try unexpected combinations for surprising and fun spatial impact,” says Lucena-Orr.

“Architects and designers, as well as their clients, seem to have shaken off the gloom of the lockdown years and are expressing a profound sense of freedom through paint colours that epitomise playfulness and joy.”

The judges have a challenging task ahead but, as five of Australia and New Zealand’s most experienced architects and designers, each adept at using colour assertively in their own work, they have a keen eye for exemplary design, innovation and execution.

The 2024 judging panel comprises Shaun Carter, Founder of Carter Williamson; Monique Woodward, Co-Founder of WOWOWA Architecture; Sarosh Mulla, Director of Pac Studio; Eva-Marie Prineas, Founder of Studio Prineas; and, Nick Travers, Co-Director of Technē Architecture + Interior Design.

The 38th Dulux Colour Awards winners will be announced at an exclusive event at Sydney Opera House Bennelong, during Vivid Sydney on Wednesday 29 May.

INNOVATIVE ‘LOW STRESS’ DESIGN

With its innovative design and patented ‘post/fuse’ system, DOLRE

‘Regular’ barrier delivers MASH TL4-rated protection while limiting the maximum transverse force transmitted to the bridge deck to less than 44 kN/post (22 kN/metre), which equates to only 14% of the ultimate outward transverse design load as per AS5100.2-2017.

What’s more, at around 120 kg/m installed, DOLRE bridge tra c barriers are significantly lighter than many AS5100 ‘Regular’ / MASH TL4-rated barrier alternatives.

SEAMLESS PROTECTION WITH DOLRE TL4 TRANSITIONS

DOLRE transitions have been designed and tested to provide full longitudinal load transfer between the bridge tra c barrier and connecting roadside barriers.

The DOLRE ‘Regular’ barrier, together with the DOLRE transitions and Thrie-Beam barriers create an engineered continuum of MASH TL4 protection – delivering maximum safety for road users onto and across the bridge structure.

CHOICE OF PERFORMANCE LEVELS

WHERE PERFORMANCE AND AESTHETICS MEET

DOLRE’s clean, uncluttered lines and aesthetically pleasing design make it an ideal match for a wide variety of bridge designs and locations. The design allows for rapid installation, as well as rapid repair and reinstatement of the barrier following an impact. DOLRE is also easy to dismantle and remove in times of flood, thereby helping to significantly reduce the risk of damage to valuable bridge assets caused by flood-borne debris.

DOLRE is also available with an extensive range of standard or custom fascia designs and integrated lighting options.

Available in a range of AS5100-2017 performance levels, including DOLRE Low (MASH TL2 | EN1317 N2), DOLRE Regular (MASH TL4 | EN1317 H2) and DOLRE Medium (MASH TL5+ | EN1317 H4b), there is a DOLRE barrier to suit virtually any bridge, culvert or road embankment application.

All DOLRE systems feature three rails - two rails for the initial vehicle impact and one rail to resist rollover – and one post design per system type, suitable for both sides of the bridge.

Ideal for bridge refurbishment and safety upgrade projects, DOLRE’s ground-breaking ‘low stress’ design restricts the outward transverse force transmitted to the bridge deck during a vehicular impact to a fraction of the bridge deck's capacity, thereby minimising the risk of damage to the bridge deck and structure during a vehicular impact.

DOLRE bridge tra c barriers can play a significant role in extending the serviceable life of many existing bridges - delivering AS5100 and AS3845 compliant protection without the need for expensive deck strengthening works or additional reinforcement.

HOW WELL DO YOU KNOW YOUR STEEL?

CAN

The reinforcing and structural steel markets are not immune to these pressures. With products being supplied from multiple sources, there are often questions regarding compliance with material Standards, the origins of products and/ or traceability through the supply chain.

As the steel supply chain comes under increasing pressure to demonstrate compliance, important questions are raised, including:

• what are the risks of receiving non-compliant material?

• how can we reduce these risks? and

• how do we help to ensure that end-users are getting products that are fit for purpose and meet the relevant Australian and New Zealand Standards?

All products used in building and construction need to comply with the relevant quality and safety standards. For buildings, they fall under the Australian National Construction Code (NCC) or the New Zealand Building Code (depending on jurisdiction), while for infrastructure projects, nominated Standards for compliance are specified. Legislation already exists in a number of states, but increasingly, it is being mandated that all parties along the supply chain of building products need to ensure compliance. In addition, we are also now seeing increasing requests along the materials supply chain for independent compliance monitoring and certification by a trusted third party.

NEW QR CODES

ACRS – EXPERT, INDEPENDENT, THIRD-PARTY STEEL CERTIFICATION

For reinforcing and structural steels, ACRS has a 20-year history of ensuring that both the manufacturers of steels, together with the downstream processors of reinforcing steels, are meeting the requirements of the relevant Australian/New Zealand Standards. This includes mechanical and geometric testing, along with product traceability from source to site.

The ACRS certification process involves an annual on-site assessment of all certificate holders, conducted by experts in steel making. These assessments are further enhanced through witness and independent testing, along with ongoing surveillance of material quality as outlined in the Standards. The ACRS Product certification scheme is independent of manufacturers and holds JAS-ANZ accreditation.

Australian and New Zealand Standards stipulate that all materials, including those being processed downstream, need to be traceable back to the source. They recognise that changes are made to the material and geometric properties of steel during the manufacturing processes.

As a consequence, the Standards require additional testing to be carried out after downstream processes have been completed.

For reinforcing steel, downstream processors include mesh manufacturers and facilities that cut and bend reinforcement to the scheduled lengths and shapes.

For mesh materials there are requirements for geometry, material properties and weld capacities of the joints. For reinforcing bar, the process of straightening and bending may change the mechanical and geometric properties of the product.

Unfortunately, in some cases, a product that was a compliant material from the steel manufacturer is delivered to the end user in a non-compliant state as a result of the downstream processing.

The ACRS scheme monitors all the requirements of the Standards, including testing requirements and traceability, thus providing users of ACRS-certified steels with assurance that the received product is compliant, mitigating risk to the builder.

To ensure that the ACRS-certified product is installed, it is essential that ACRS-certified product is specified up-front, and throughout the procurement process. Importantly, all steel should be checked for compliance when it arrives on site.

In accordance with the relevant Standards, all ACRS-certified products have markings and tags for traceability. Under the ACRS scheme, all tags need to meet the requirements of the relevant Standards and must also include the ACRS Logo and/or certificate number.

The scope and validity of suppliers’ certificates should also be verified in this process.

ACRS certificates all now carry a QR code to circumvent fraudulent certificates. The QR codes may be scanned using the free ACRS Cloud app which is available for download from https://steelcertification.com/cloud

If the QR Code is valid, the app will display the scope of accreditation and other details regarding the certificate in question.

By ensuring that ACRS-certified steel is specified and supplied, the builder/ installer is ensuring the steel products meet the requirements of the relevant Australian and New Zealand Standards, thus minimising the risk of:

3. serious reputational damage.

Specifying and ensuring ACRS-certified products are supplied is as simple as looking for suppliers and processors with the ACRS brand. It is important to remember that any break in the traceability chain may call into question your product's compliance.

1. having to replace product with unknown origins

2. delivering a structure that is not fit for purpose

ACRS CLOUD

Recognising the industry's move to digital systems and to ensure confidence in the ACRS scheme is maintained, ACRS has launched ACRS Cloud - a digital verifiable conformance scheme. By combining certification and digital product traceability, ACRS will be a trust anchor, providing confidence and traceability to the market.

ACRS Cloud is the first digital certification system of its kind for steel in the Australian and New Zealand construction industries. ACRS Cloud gives steel buyers and users instant assurance over product certificates at the touch of a button - in a secure environment - to provide confidence in products’ conformance to AS/NZS Standards.

Users throughout the supply chain can gain product peace of mind by checking the nature and authenticity of ACRS steel certificates in the new ACRS Cloud app, which is available free on Apple and Android.

The ACRS Cloud system will see batchspecific tags with QR codes put onto steel at steel producers, fabricators, and processors. At each point, these QR codes (and/or those on ACRS certificates) can be scanned on-site to instantly identify the source of a product and its certification details against a ‘single source of truth’, including batch number; bar and tag markings; and verification of product conformance to provide full traceability through the supply chain.

Just like via the ACRS online database, you will be able to search for certificate holders by mill name or country and report any concerns, all in the app.

For certainty over the steel you use, make sure you are specifying ACRS-certified steel, and checking conformance easily in the new ACRS Cloud app. Find out more at: https://steelcertification.com/cloud

Designed and prefabricated off site, light gauge steel (LGS) framing made from TRUECORE® steel allows a critical aged care facility to be built on schedule and on budget

Located at Sunrise Beach in the Noosa Shire, Phase 1 of the Sunrise Beach Aged Care facility is scheduled to be complete by mid December 2023. In an area where the demand for aged care is growing faster than most other parts of Australia, the first 102 residents will be welcomed into their quality new homes early in 2024.

By utilising LGS made from TRUECORE® steel for the walls, trusses and bracing, the project achieved the following benefits:

PREFABRICATED FOR A FAST BUILD

Designed and prefabricated off site, LGS framing required builder Badge Constructions to work closely with fabricator Ultimate Steel Framing in a more considered manner, right from the start of the project. Items such as safety, PWD rails and TV recess areas were all factored into the framing from the start, helping to reduce mistakes and delays.

LIGHTWEIGHT AND STRONG FILLS THE DESIGN BRIEF

The brief for the Sunrise Beach Aged Care Facility required the provision of a true “domestic” living experience with small clusters of private rooms centered around courtyards or views. With an impressive strength to weight ratio, LGS framing made from TRUECORE® steel supports wide spans that form the backbone of these light-filled villas.

TERMITE PROOF WITHOUT INSECTICIDES

LGS framing made from TRUECORE® steel is termite proof and doesn’t require treatment from insecticides. For client Uniting Care Queensland (UCQ), this was an important consideration for its residents. Additionally, TRUECORE® steel won’t warp, twist or shrink even in Queensland’s tropical environment.

LIGHTWEIGHT AND EASY TO HANDLE

Lightweight and strong, LGS framing made from TRUECORE® steel can be easily handled on site with fewer tradespeople. Consequently, labour was split into smaller groups to work on multiple fronts, further speeding up on-site progress.

PROJECT HIGHLIGHTS

Reflecting recommendations set out by the Royal Commission into Aged Care Quality and Safety, each of the private accommodation rooms at Sunrise Beach Aged Care Facility is designed to operate like a small household, offering residents a better lifestyle and superior quality of care.

Pino Gentile, Principal Architect at Thomson Adsett, articulates his brief. "The design of the Sunrise Beach Aged Care Facility responds to ‘Person Centred Care’. Homes are designed to provide residents with an authentic domestic experience and are modeled in small clusters of 8-9 private rooms. Each room is located around a series of light-filled courtyards, or alternatively provides views of the adjacent national park. Residents can easily access common areas and spaces in order to socialise or get food and drink from the house kitchen whenever they want to.”

In a location where the demand for aged care accommodation is continuing to grow faster than most other parts of Australia, the timely provision of quality new homes for residents is critical.

Using LGS framing made from TRUECORE® steel, Builder Badge Constructions was able to significantly reduce construction time, which will be critical to completing Phase 1 of the facility by mid December 2023. In early 2024, 102 residents will be welcomed to their new homes in this next generation aged care facility.

Mitchell Crisp, Principal of fabricator Ultimate Steel Framing said "LGS framing made from TRUECORE® steel has allowed us to work around the limited onsite space. Smaller cranes were used, saving costs and positioning packs in out of the way locations. The ease of handling LGS frames meant labour could be split into smaller groups to work on multiple fronts, again helping accelerate the rapid progress of the job.”

“We are thrilled with the building speed achieved through the adoption of light gauge steel (LGS) framing. Choosing steel has more than paid for itself in construction time savings.”

UnitingCare’s Group General Manager Property, Lavinia Dack

LGS framing made from TRUECORE® steel has the added benefit of staying straight and true. The framing is precision made and remains accurate to measurements. Prefabricated LGS frames made from TRUECORE® steel also have the benefit of having pre-punched service holes, which allows follow-on trades to feed services through the framing for a fast install without the need for additional drilling.

The Sunrise Beach development is one of the largest applications of LGS in the Noosa region, including over 40,000 lineal metres of TRUECORE® steel. Supplied by Australian steel manufacturer BlueScope and fabricated locally by Ultimate Steel Framing, TRUECORE® steel supports UnitingCare’s commitment to use local suppliers.

NCC COMPLIANCE WITH AUSTRALIAN-MADE AND TESTED LYSAGHT® STEEL BUILDING PRODUCTS

The National Construction Code (NCC) plays a crucial role in ensuring the safety, health, and amenity of buildings in Australia. To enhance compliance with the NCC, two key measures - specifying Australian-made steel building products and conducting product testing according to Australian Standards - can prove instrumental. This feature delves into the significance of these measures in maintaining and elevating construction standards across the Australian building industry.

• Specifying Australian-made steel building products: Choosing Australianmade steel building products aligns with the broader goal of supporting the domestic industry. A preference for locally sourced materials not only contributes to the national economy but also holds distinct advantages for compliance with the NCC.

• Quality Assurance: Australian-made steel products are subject to stringent quality control measures. These products consistently meet, and often exceed, industry standards, providing a foundation of structural integrity and reliability.

• Traceability: The transparency embedded in the supply chain of Australianmade products facilitates traceability, a critical factor in satisfying the NCC's stringent requirements, which demand a meticulous understanding of the origins and composition of construction materials.

• Environmental Considerations: Beyond quality, the emphasis on environmentally sustainable practices in locally produced steel aligns seamlessly with the NCC's commitment to fostering sustainable building practices.

• Timely Delivery: Reduced lead times for Australian-made products contribute significantly to timely project completion — an aspect intricately tied to the NCC's stringent timelines and requirements.

PRODUCT TESTING TO AUSTRALIAN STANDARDS

In tandem with the specification of Australian-made steel products, subjecting materials to thorough product testing according to Australian Standards emerges as an indispensable step in ensuring compliance with the NCC. This facet delves into the realm of safety, performance, and the durability of building materials.

• Safety Assurance: Rigorous testing, a hallmark of Australian Standards, provides designers with reliable product performance data to inform their structural design removing ambiguity and reducing the risk of structural failures, thus securing occupant safety - a cornerstone of NCC regulations.

• Durability: Product testing scrutinises the durability of materials, aligning seamlessly with the NCC's emphasis on longevity and resilience in building construction. This aspect not only safeguards investments but also contributes to the sustainability of structures over time.

• Compliance: Meeting the specified Australian Standards inherently ensures compliance with the relevant sections of the NCC. This provides a streamlined and coherent approach to regulatory adherence, reducing complexities in navigating the NCC landscape.

By crafting tailor-made solutions like a 21-metre Table Lifting System, Doka has helped boost construction efficiency on the second-highest building in the US city of Detroit.

The Hudson’s Site project, a mixed-use development located in downtown Detroit, Michigan, includes two buildings: a 209-metre high-rise tower and a 70-metre mid-rise building, separated by a through-cut. The tower will house modern offices, event venues, high-tech residences, and a luxurious 5-star hotel. It is expected to be completed in 2024 and will be the second tallest building in Detroit after the Renaissance Center.

To meet the special requirements of the project, which has limited on-site space due to its urban location, Doka developed a system that eliminates the need for traditional crane lifts between level-tolevel transitions. Doka’s engineers came up with a self-climbing Table Lifting System solution, spanning a total of 21-metres, that is exclusively designed to lift slab formwork across six levels of the Hudson’s Site Tower. The hydraulic Table Lifting System not only increases efficiency by strongly improving the speed

of material hoisting, but also helps ensure safety – a paramount aspect in every Doka endeavour.

Additionally, the adaptability of Doka's Framed formwork Frami S Xlife system proved essential in navigating the project's 112 different column cross-sections. Brian Gulick, Superintendent with Barton Malow, commented: “Doka’s personalised Table Lifting System enabled us to operate the construction site without the use of crane lifts between level-to-level transitions, which helped us to optimise construction speed.”

Doka’s cutting-edge BIM Revit model is designed to analyse potential suspension points of the climbing systems of the core and slabs, detecting and preventing possible clashes on site by recoordinating the schedule in advance. Doka ensured early-on that the right solutions were in place for this complex project by collaborating closely with all stakeholders, which enabled the project to stay on track and meet its ambitious schedule.

Doka’s engineers faced further challenges, such as providing the right formwork solutions for the skyscraper’s unequally-shaped core. Doka crafted

NEW 100% RECYCLABLE MANHOLE & STORMWATER PIT FORMWORK

In an Australian first, a local specialist manufacturing company has introduced a new version of manhole formwork made from HDPE plastic as a proven alternative to the heavy steel used on construction sites since the 1920s.

Plastic Formwork Hire has reimagined the production of conventional steel manhole and stormwater pit formwork and introduced a 100% recyclable HDPE plastic version, removing costly management and maintenance issues previously associated with the development of stormwater pits and manholes.

Manufactured from a lightweight and durable High-Density Polyethylene (HDPE) material, the HDPE Formwork is designed to be portable and easy to assemble. It removes the need for heavy transport haulage and machine installation for heavy steel forms, amongst other efficiencies.

Owner and founder Trevor Davis came up with the concept after years of cleaning and repairing steel forms in the sandblasting and industrial painting industry.

“While construction materials and processes have changed dramatically over the years, the use of heavy, steel formwork hasn’t altered since the 1920s.”

“Steel formwork is inherently difficult to manage and maintain, and will cost construction projects

countless man-hours in storage, maintenance, cleaning, installation, and transport,” he said.

“HDPE plastic liners had already been introduced as a requirement for the internal walls of manholes to protect the concrete from sewage gasses. It is strong, flexible, and easy to install, so it made perfect sense to use the material in the manhole forms.”

The HDPE formwork does not rust or degrade, it will not bend out of shape and can be fitted together easily by one person. The lightweight panels are easy to lift and assemble and can be cleaned with a pressure hose or cloth,” Trevor said.

Trevor and his team have spent over two years mastering the designs and piloting the formwork. The products are NATA-certified and have been tested in some of the most rigorous conditions.

“One of the most frequent pieces of feedback we receive is how much lost time has been saved by site workers in installation and cleaning. Foremen cannot believe that heavy haulage transport and lifting equipment are no longer required for starters. It has simplified the process in ways that no one had ever envisaged,” Trevor continued.

Plastic Formwork Hire provides delivery and collection within 25km of a hire depot at no cost and cleaning after use is included in the hire price.

Jim Carruthers from Carruthers Contracting is an

a custom-made formwork solution featuring the large-area formwork Top 50, and the Super Climber SCP, which is recognised as one of the fastest selfclimbing formwork solutions on the US market. A mini crane mounted at the top level of the Super Climber, supported the installation of heavy steel embeds, which significantly reduced the crane’s period of use. This tailored solution achieved an average five-day cycle time instead of the usual seven-day cycle time, resulting in a significant acceleration of the construction while increasing efficiency and safety. What’s more, an integrated concrete placing boom facilitated the concrete pouring of the core, slabs and columns.

A self-climbing Xclimb 60 Protection screen was designed for slab edge protection, as were several screens with integrated storage platforms as an extra feature.

early adopter of the HDPE Formwork and has been using it on sites for almost two years. He said his team loves it because it is extremely easy to set up, disassemble and especially move.

“(The formwork) is a lot easier to use and clean and it only takes a couple of guys to bolt it together and install it. We don’t need machines to lift it in and out,” he said.

“As far as costs go, there are a lot more efficiency and a lot of cost savings when you don't need to pull an excavator off another job to drive over and back just to lift forms.”

The HDPE comes in a range of sizes and form types that can be ordered via an online booking website that offers incentives for advanced bookings.

As part of Plastic Formwork Hire is currently recruiting regional distributors to manage dispatch and local inventory.

THE SIGNIFICANCE OF COMPLYING WITH AS/NZS STANDARDS FOR METAL DECKING IN CONSTRUCTION

When it comes to constructing buildings and infrastructure, the use of metal decking has become increasingly popular due to its numerous advantages over traditional materials. Not only does metal decking offer exceptional strength and durability, but it also provides significant cost savings and contributes to faster construction times.

However, to ensure the highest quality and safety standards, it is crucial to comply with relevant industry standards.

In this article, we will delve into the importance of complying with three essential Australian/New Zealand standards: AS/NZS2327, AS/NZS1397 for metallic coated steel products, and the fire rating to AS/NZS1530.

1. AS/NZS2327 – COMPOSITE STRUCTURES FOR BUILDINGS.

AS/NZS2327 is the standard that governs the design and construction of composite steelconcrete structures for buildings. It outlines the requirements and specifications for composite slabs, beams, and columns that incorporate metal decking as a crucial component of the structural system.

Compliance with AS/NZS2327 ensures the following:

a. Structural Integrity: Buildings constructed with composite steel-concrete structures using metal decking will have superior strength and load-bearing capacity, ensuring the safety of occupants and longevity of the structure.

b. Stability and Resilience: Compliant metal decking solutions contribute to the stability and resilience of the building, making it better equipped to withstand external forces such as seismic events and extreme weather conditions.

c. Code Compliance: Following AS/NZS2327 demonstrates adherence to nationally recognized standards and guidelines, which may be a legal requirement and is essential for obtaining necessary permits and approvals from regulatory authorities.

2. AS/NZS1397 – METALLIC COATED STEEL PRODUCTS.

AS/NZS1397 specifies the requirements for continuously hot-dip metalliccoated steel sheet and strip products. These products, commonly used for metal decking, are coated with materials like zinc or zinc-aluminium alloy to enhance corrosion resistance and increase the service life of the decking material.

Compliance with AS/NZS1397 offers the following advantages:

a. Corrosion Resistance: Metal decking manufactured in accordance with this standard will have superior resistance to corrosion, even in harsh environmental conditions, which is critical for ensuring the long-term structural integrity of the building.

b. Quality Assurance: Following the requirements of AS/NZS1397 guarantees that the metal decking meets stringent quality standards and has undergone testing to ensure its suitability for construction purposes.

c. Sustainability: Longer-lasting metal decking reduces the need for frequent replacements, contributing to a more sustainable construction industry by reducing material waste.

3. FIRE RATING TO AS/NZS1530 – METHODS FOR FIRE TESTS ON BUILDING MATERIALS, COMPONENTS, AND STRUCTURES.

AS/NZS1530 outlines methods for determining the fire performance of various building materials, components, and structures, including metal decking. It assesses the reaction to fire, spread of flame, and the ability of the material to resist fire and heat.

Complying with AS/NZS1530 for fire rating provides the following benefits:

a. Fire Safety: Metal decking that meets fire rating standards contributes to the overall fire safety of the building, allowing occupants more time to evacuate in the event of a fire.

b. Building Code Compliance: Many building codes mandate adherence to specific fire rating standards for different building elements. Complying with AS/NZS1530 ensures that the construction is in line with these codes and regulations.

c. Insurance and Liability: Insurance companies often require buildings to meet specific fire safety standards to provide coverage. Compliance with fire rating standards reduces potential liability and insurance risks for building owners and stakeholders.

Complying with AS/NZS2327, AS/NZS1397 for metallic coated steel products, and fire rating to AS/NZS1530 is of paramount importance in the construction industry. These standards collectively ensure the structural integrity, durability, and fire safety of metal decking systems, contributing to the overall safety and reliability of the buildings in which they are used.

AUSSIE HYDRAULIC TANKER PUMP A WINNER

Australian Pump Industries are pleased to report the huge take up of their high-flow cast iron semi-trash hydraulic drive pump. The 3” self-priming pump, called the Aussie B3XR-A/ST, is close coupled to a powerful 22 cc hydraulic motor that makes for a compact installation and less maintenance.

With a maximum flow of 1,500 litres per minute and a maximum head to 31 metres, the big 3” pump can handle a wide range of applications, including dust suppression, drill rigs, tankers, mine dewatering and moving contaminated water.

Hydraulic drive pumps derive their power from the main engine of the vehicle or equipment on which they are mounted. Thus, operators can get the advantages of virtually unlimited power, delivered through a flexible drive system that doesn’t depend on shaft or separate engines.

The flexibility of the drive system and the compact design means the pump can be placed

in the most appropriate location, with huge operational cost reductions and advantages.

These advantages include a major reduction in maintenance costs and labour with the elimination of a separate petrol or diesel engine to drive the pump.

“This pump really suits applications in the tanker market - delivering a high flow, hydraulic drive pump that will handle dirty water,” said Aussie Pumps Product Manager Dolphie Mascarenhas.

“At a maximum head of 26m the pump will deliver 800lpm flow. That’s impressive for a 3” self-priming semi-trash pump.”

“Not surprisingly, we’re seeing a lot of tanker operators upgrading to the Aussie B3XR-A/ST from their existing pumps, many of which have significant performance issues - particularly when it comes to dealing with the harsh Australian operating conditions and dirty water,” he said.

The 3” pump has excellent self-priming characteristics, with the ability to draw water from pits of depths of 6 metres. It has been designed to pass solids up to 35mm, making it suitable for handling solids-contaminated water.

The new Aussie semi-trash pump is fitted with a silicon carbide mechanical seal with an alumina counterface with nitrile rubber elastomers. It also features a stainless steel wear plate and stainless steel motor shaft.

The pump includes a front opening clean-out port that makes it easy to access the pump’s internals. That’s a huge advantage as this means the unit can be cleared of chokes in situ without having to dismantle pipework.

The hydraulic motor requires 22cm3 per rev at 150 bar pressure, that’s equivalent to 7.5kW.

“We chose Italian hydraulic motors because of their reputation for quality and commitment to aftermarket support,” Dolphie said.

The big pump is also available with a cast 316 grade stainless steel impeller making it suitable for handling more abrasive liquids.

For applications that are really corrosive, Aussie offers a fully cast 316 stainless steel pump. These have been installed in tankers used for transporting whey from dairies in Tasmania and are even in use with the Australian Army.

Like all Aussie Pump products, the units are designed and built to ISO 9001 quality standards. Australian Pump believes that users deserve the best quality and won’t offer any product that is not built to their stringent requirements. These Aussie GMP pumps come with a 3-year warranty against faulty workmanship or material.

Further information including a free catalogue is available from Australian Pump Industries 02 8865 3500 and online at: aussiepumps.com.au

The Aussie 3” B3XR-A/ST semi-trash pump with hydraulic drive is a compact installation, delivering high flows with minimal maintenance required.

By offering a comprehensive fuel and lubricant offering, Caltex is a one-stop-shop, with solutions available for every kind of application, from construction to mining, agricultural, power generation, transport, and global marine.

TOP-TIER LUBRICANTS AND FUEL THAT KEEP YOU MOVING

Protecting your investment in plant equipment with high-quality lubricants simply makes sense. Caltex Delo® with ISOSYN® Technology, helps protect vital diesel engine parts, provide engine durability and extend service intervals, to help minimise operating costs.

Drawing on over 88 years of expertise, ISOSYN® Technology combines premium base oils with high-performance additives to deliver engine component protection rivalling synthetics.

This high-performance additive formulation helps provide exceptional soot dispersion and prevent deposit build-up, ensuring vehicle performance which can contribute to extended service intervals and minimised downtime.

The road to the modern-day Delo® range is one based on marketplace innovation.

In 1935, Chevron, then known as Standard Oil of California, partnered with Caterpillar Tractor (CAT) to formulate an oil to lubricate the highspeed diesel engines that CAT was planning to build.

This joint venture between the two companies resulted in a multipurpose motor oil known as Delo®, an acronym for Diesel Engine Lubricating Oil. In the 1940s, Delo® was the first brand in the world to develop compound diesel engine oil that could be used in any diesel engine, and in the 1950s, it pioneered the first successful multi-grade engine oil, with innovations over the following decades setting industry benchmarks for long-term engine performance.

Adding further confidence, Chevron has the capabilities to manufacture lubricants by producing its own base oil, maintains 21 individual blending plants, globally (including

joint ventures) and owns Oronite, one of the world’s biggest additive companies.

Delo products are sold in 155 countries, and importantly, Chevron internally controls the three pieces required to manufacture lubricants, by producing its own base oil, it controls Oronite, one of the world’s biggest additive companies, while it also maintains 21 individual blending plants globally, including joint ventures.

Today, Delo® products are sold in 155 countries, and the Caltex Delo® product family includes lubricants, coolants, greases, and construction equipment system consumables such as engine oils, hydraulic system oil, transmission oils, engine antifreeze/coolants, gear drive fluid, grease for bearings and other lubrication points and more.

Similarly, this offering extends to all other fleet vehicles, including trucks, trailers, and passenger vehicles, with the Havoline® brand of oils covering the full spectrum of petrol engines.

Caltex with Techron® is available across all petrol fuel grades and contains an innovative formulation that has been scientifically proven to help clean and protect engines. Techron® not only removes dirt, but also helps prevent deposits from forming on critical parts of your car’s engine. This helps your car’s engine to function at optimum, delivering maximum power to your wheels.

Caltex Diesel with Techron D helps keep fuel injectors clean, protect against corrosion and reduce foaming while filling up.

In diesel engines, the fuel injector nozzle can be as narrow as the width of two human hairs, and with these injectors usually located inside the combustion chamber, they are exposed to extreme heat, and are, therefore, more vulnerable to deposit formation than those experienced in a petrol engine.

STARCARD STREAMLINES BUSINESS OPERATIONS

The new Caltex StarCard is a power-packed fuel management card offering a convenient way to increase fleet management efficiency. It provides a wide range of adaptable features to manage fleet and personal expenses and is perfectly suited to the ever-changing requirements of working in the construction industry.

TECHNICIANS IN HOT WATER

Recently, Aussie Pumps hosted a Masterclass on servicing hot water pressure cleaners. The aim was to both train service technicians and to demystify the mechanics behind the machines. The participants were taken through the basics of the hot water machines and shown how by careful design, Aussie Pumps range of steam cleaners have been tailored for Australian conditions.

“When we set out to sell hot water and steam pressure cleaners in Australia, we knew that the standard European machines did not measure up to the local conditions,” said Aussie Pump’s Chief Engineer, John Hales.

“Reliability is vital, especially on busy construction sites and quarries where the breakdown of the steam cleaner can mean longer maintenance times for identifying hydraulic leaks and engine issues with major consequences,” he said.

Aussie Pumps set out to design key features into their machines that gave users advantages they felt were essential, without including overcomplicated components with the potential to fail.

A prime example is Aussie’s Admiral 4000 steam cleaner - a 4,000 psi steam cleaner with increased capability but with the advantage of using less water consumption.

The Admiral can save time, water and electricity in the cleaning process. The 4,000 psi capability, with flows to 15 lpm, means it can move caked-on debris fast, delivering huge time savings. It’s the combination of steam (up to 130°C), 4,000 psi pressure and huge flow, that get the jobs done faster.

The operator has the ability to vary both pressure and heat from the control panel to optimise performance and cleaning efficiency.

All of Aussie’s hot water machines come with four-pole motors and slow speed, heavy duty European triplex pumps. They provide a longer and trouble-free life. The range includes both single and three-phase options with pressures ranging from 1,800 psi all the way up to 4,000 psi.

They also come with stainless steel covers, replacing the traditional European-style plastic cover, a steel chassis (which is stronger and longerlasting than polypropylene) and four wheels, not castors, for ease of movement on uneven surfaces.

“Aussie’s machines are streets ahead of imports,” said Hales. “They feature a wide range of protection devices that are aimed at providing the maximum convenience for the operator, including Timed Total Stop, Auto Shut-down, Micro-leak Detection, and Low Fuel sensor with warning light."

“What the Masterclass taught our technicians was that Aussie’s steam cleaners are as tough on the inside as they look from the outside,” John Hales added.

Aussie Pumps has comprehensive workshop manuals for servicing hot water machines available free of charge.

STRUCTURAL

STEEL AND REINFORCED CONCRETE: HOW STANDARDS HAVE CHANGED OVER THE YEARS

by Paul Uno, Director, ETIA

When I graduated from the University of Sydney in the mid-1970s, engineers used AS1250-1972 and AS1250-1975 for their structural steel design, AS1480-1974 for their reinforced concrete design, and AS14811978 for their Prestressed Concrete Design. These days we use AS36002021 for both reinforced and prestressed concrete design, AS4100-2021 for structural steel design and AS3990-2016 for mechanical engineering steelwork.

So, what has changed in these Standards (or Codes, as we called them in those days) over the past 50 years, and what were the reasons for these changes?

STRUCTURAL STEEL

When I worked for Transfield as a structural engineer designing steel structures (e.g. transmission towers, foundations and water retaining structures) we used the AS1250-1974/1981 Structural Steel Code. The common steel grade used in those days for nearly all structural elements including UB, UC, and angles, was 250 grade yield stress (though less common higher grades were available).

The commercial (or black) bolts were mainly grade 4.6 (i.e. 400 MPa ultimate tensile capacity and 240 MPa yield capacity). You could get 8.8 grade bolts (i.e. 800 MPa ultimate tensile capacity and 640 MPa yield capacity) but these bolts were much more expensive than commercial bolts so most engineers and builders used 4.6 bolts.

The structural design principles set out in AS1250 were based on Working Stress (Serviceability), i.e. “everyday loads”, not factored loads.

This Code, therefore, was not only used by structural and civil engineers but also mechanical engineers (who focus primarily on serviceability in their designs), whereas structural engineers focus on both strength and serviceability.

Around the mid-1970s-80s, engineering academics and Standards committee members decided to follow overseas trends and move towards Ultimate Strength Design principles (USD). The other terms used were Limit State (LS) or Load and Resistance Factored Design (LRFD).

In America, one of the leading figures pushing LRFD was Theodore Galambos (Prof of Civil Engineering at Washington University) and many of his papers on the topic featured in the American Institute of Steel Concrete (AISC) journals and magazines.

I worked at the Australian Institute of Steel Concrete (AISC) - now called ASI (Australian Steel Institute) - in the late-1980s and was on the Standards Committee BD1 looking at changing AS1250 from working stress to a limit state format. Many of the committee members wanted to keep 1250 as the number in the title of the Standard. I pointed out that in days to come, no one would know whether the AS1250 Code used on a project was the Working Stress version or the Limit State version, so a new number should be chosen. I was over-ruled in my proposal, however, when I returned to the AISC office and spoke to my boss (Arthur Firkins) and explained the situation, he agreed with me and made it his focus to get the number changed. Suffice to say, he was successful and it then became AS4100.

However, the dilemma for mechanical engineers is that they only design in “working stress” due to the nature of mechanical structures (e.g. fatigue, vibration which are all working load related). With that in mind, they produced their own Australian Standard to replace AS1250 and it became AS3990-1993 ‘Mechanical Steelwork’ which covered boilers, pressure vessels, lifts, cranes, mining equipment, gas and liquid petroleum piping systems and bulk handling equipment.

The current Steel Standard, AS4100-2021, utilises Limit State Design principles, 300 MPa yield stress steel (up from 250 MPa) as the common grade, and 8.8 Grade bolts as the common bolt connection type (costs now being very competitive to the original 4.6 bolts). Higher grades of steel are also available (350, 400 etc).

In other metals-related Standards, even the Aluminium Code AS1664-1979 changed from its working stress format to a limit state format in 1997 (AS1664-1997).

REINFORCED CONCRETE

The Reinforced Concrete Code AS1480-1974/1982 and Prestressed Concrete Code AS1481-1978 were merged into one Standard called AS3600 in 1988. This merger of the two Codes occurred due to pressure from the prestressed industry who thought few engineers embraced PSC/PT because it appeared too different to reinforced concrete.

However, it must be stated that the AS1480 and AS1481 Standards were already in Ultimate Strength format, and so preceded the Steel Code in changing to the new format by about 10 years.

The other Australian Standard relating to reinforced concrete that has changed substantially from its inception in 1986 to the present day was AS2870 Residential Slabs and Footings Standard. Its current version is AS2870-2011, however, during the period from 1986 to the current version, there were four major revisions: 1988, 1990, 1996 then finally 2011. This Standard is different to AS3600 in many ways, in that it focuses primarily on Serviceability (i.e. crack control) with structural strength being the secondary issue to check.

ETIA WORKSHOPS

ETIA will be conducting a face-to-face 2-day workshop on Structural Steel Design to AS4100 in Brisbane, QLD from 29-30 April 2024. Similarly, ETIA will then be conducting a 2-day face-to-face workshop on Residential Slabs and Footings (Design and Construction to AS2870) in Brisbane, QLD from 2-3 May 2024.

Both workshops will be held at the Voco Hotel, 85-87 North Quay (Cnr. Ann Street), Brisbane, QLD. For registrations and information on these or any other ETIA workshops, please visit the ETIA website: www.etia.net.au

Located at 168 Walker Street, on the edge of the rapidly transforming North Sydney CBD, AURA is nearing completion, with Aqualand having recently marked the construction of its uppermost floor, which rises 28 storeys above the streetscape, with a topping out ceremony.

This period in AURA’s construction is an interesting time, according to Aqualand’s Executive Director Development & Construction, Tom Catalovski, as the various ‘layers’ of luxury are briefly visible at various stages throughout

they’re generally referring to the quality of the fixtures and fittings – the elements of the residence on show and used on a daily basis, such as counter tops, cabinetry, tiling, tapware, lighting and the flooring, for example,” Tom said. “And as these fittings are currently being installed floor-by-floor in AURA, the fact that they epitomise ‘luxury’ is clearly evident.”

“But our idea of ‘luxury’ goes beyond the surface to also describe the additional features we’re building into future-proof the structure, the layers that won’t be seen when the fit outs are complete. In fact, most residents won’t ever know about the additional luxurious features we’re electing to install into AURA,” he said.

“While we’re installing our hand-selected marble, which was inspected on various site visits to quarries in Greece, and highgrade direct-fix timber flooring, it’s really what’s underneath this layer that defines our

double-glazed façade windows providing acoustic protection, for example.”

“Many people assume developers install bottom-of-the-range fittings and fixtures of a perceived quality brand and position them as the best quality. However, at Aqualand, we go to great lengths to ensure all the inclusions are best-in-class, and what’s installed is exactly to our strict specifications and meets our high expectations.”

“We intend to be in the luxury market for generations to come, so our reputation for delivering the best possible quality is of paramount importance to us. That’s why we developed our own in-house construction arm, to ensure our build quality is second to none and truly lasts the test of time,” Tom added.

“We go to great lengths to meet and exceed the standards mandated by the Building Code of Australia. For example, we appoint industryleading independent peer review consultants, ensure we adopt their recommendations and implement best-in-class procedures with our building standards.”

“It’s the details you don’t see, behind the walls, floors and ceilings that gives our clients security over time, and this is especially important when there’s such an industry focus on building defects.” he said.

“We’ve also gone above and beyond by hiring a team of independent tier one consultants to conduct peer reviews of the entire design and construction process initially specified by our tier one project team, which includes world-renowned architects

Woods Bagot, Richards Stanisich and Turf Design Studio, and service and structural consultants BG&E, Shelmerdines, WSP and Webb, plus all the top contractors and premium suppliers, such as Gaggenau, Bosch, Sub-zero, Technogym, Samsung, and Parisi, to name a few. The peer review resulted in recommendations for even better-quality products being specified for example.”

Aqualand has also elected to engage a third party to undertake a peer review on quality assurance once the fit-out is complete.

“We’ve also engaged a company called Strata Defect Specialists Sydney to undertake a third-party independent defecting review, in addition to that carried out by our building team, to help ensure an outstanding experience for our customers at their pre-settlement inspections. They’ll be ensuring we’re delivering the quality our clients have come to expect of us. Again, this goes way beyond the industry standard,” Tom added.

A clearly evident aspect of AURA’s luxury offering are the oversized apartments, which exceed the North Sydney Council’s minimum building requirements. The standard size for a two-bedroom apartment in the area is 80sqm, with AURA’s measuring 95sqm, plus a wintergarden, making them well over 100sqm in total. AURA’s design was revised three times to increase the size of the apartments, with the initial plan decreasing from 448 residences to 386.

Other luxury inclusions visible to residents include the integration of the latest technology, including provisions to charge electric vehicles. A pool of Tesla share vehicles will be available for hire, all apartments will have full-fibre NBN internet connections, and Wi-Fi hot spotting will be installed in common areas throughout the entire building.

The building will also benefit from a building management system to monitor and control the building’s services to ensure efficient management and allow for early detection and rectification of any issues to ensure the building is always operating optimally.

AURA represents the fifth residential project delivered by Aqualand since the company’s launch in 2014 and is well on the way to joining a portfolio of other notable completed projects such as BLUE at Lavender Bay in Milsons Point and The REVY at Darling Island.

Aqualand Group Managing Director, Jin Lin, says Aqualand’s integrated holistic business model is another key to their success.

“We’re continuing to grow strength by strength. Even in these uncertain times, we’re

still performing strongly due to the 100% ownership of our development and internal construction arm, and other lifestyle service and hospitality business offerings.”

“Our other completed landmark projects are testament to our focus on delivering quality. This is especially attractive to our clients at a time when many other developers are struggling to find builders for their projects and buyers are asking who’s building the project as one of their very first questions. Construction quality really is top of mind now.”

“As the sole developer and builder of the state-significant Central Barangaroo precinct, our future buyers can also expect this focus to carry through to that project too. Understated luxury is our hallmark and I’m truly proud of this. Our positioning statement of ‘Live Better’ certainly rings true,” he added.

AURA will feature an extensive podiumlevel retail precinct providing residents with a curated shopping and dining destination on their doorstep, including a providore, bakery, café and wine bar, an all-day diner and a contemporary Japanese restaurant. A network of landscaped laneways will also welcome visitors into the precinct.

Other resident amenities include a lifestyle concierge service, a gym equipped with worldleading fitness technology brand Technogym, a wellness room and end-of-trip facilities. A glamorous rooftop area offers a sky sun deck, private dining rooms, and a barbecue and kitchen space for year-round al fresco entertaining.

With the industry-specific ERP-system erpbos® from Progress Group, an overview

of all business processes is guaranteed. The project lifecycle is constantly updated, allowing decisions to be made in real-time, which, in turn, helps to keep both costs and production schedules under control. The openness of the solutions makes it possible to integrate the system with existing ones.

To operate these systems effectively, R3 and Sunway have invested in training its workforce. BIM modellers, CAD-CAM specialists, technicians, and operators have all received training on the operation of software, robots, and machinery - resulting in a highly skilled and knowledgeable workforce.

The pallet stacker helps to ensure a safer and more efficient working environment.

The automated concrete spreader provides the exact amount of concrete required for each precast element according to plan, significantly reducing waste.

COLLABORATION WITH PROGRESS GROUP

The collaboration with Progress Group, a key partner in the development of the HL-Sunway Prefab Hub, has been instrumental in the project's success. Progress Group served as a turnkey solution specialist, working closely with Hong Leong Asia and Sunway from the tender stage to the opening ceremony. This collaboration extended across various phases, including sales, project management, installation, testing, commissioning, and operation.

Despite differences in time zones the collaboration has been marked by a positive relationship and effective communication. Progress Group's presence in Kuala Lumpur further facilitated timely interactions with customers, enabling responsive solutions to challenges encountered during the project.

“It was a fantastic experience working with Progress Group and its local partner in Singapore,” said Mr Kwong Tzyy En from HL Sunway Prefab Hub.

“Their effectiveness in addressing issues during machinery installation and commissioning, along with their quick response and problem-solving skills, is certainly commendable.”

“We believe such experience can greatly contribute to the success of the projects and organisations,” he added.

THE COLLABORATION BEHIND THE HUB

The development of the HL-Sunway Prefab Hub is the result of a fruitful collaboration between two prominent entities, Hong Leong Asia and Sunway Construction Group Berhad. Hong Leong Asia's wholly owned subsidiary, HL Building Materials Pte Ltd, holds a 51% equity stake, while Sunway Concrete holds 49% in the joint venture.

Stephen Ho Kiam Kong, CEO of Hong Leong Asia and Tan Sri Dato’ (Dr) Chew Chee Kin, President of Sunway Group, have expressed their commitment to integrating construction processes with a lower carbon footprint and achieving high throughput and productivity. Their shared vision emphasises sustainability and innovation in the building environment.

Dr Chew Chee Kin, President of Sunway Group, said: “Sunway and Hong Leong Asia share a common vision and aspiration in our journey towards innovation, efficiency and sustainable development for the built environment.

PROJECT: CENTRAL STATION METRO LOCATION: SYDNEY, NSW

MASTER PRECASTER: WAEGER CONSTRUCTIONS STAINING: ECOTONE

THAT TELLS A STORY

In the constantly evolving fabric of urban landscapes, the significance of visually appealing infrastructure goes beyond mere visual attractiveness. Beyond the superficial charm of well-designed structures lies a profound connection between meaning, beauty and sustainability, weaving a narrative of communal pride and environmental stewardship.

Communities that take pride in their surroundings are more likely to engage in sustainable practices. Aesthetically pleasing infrastructure that embodies meaning, becomes a symbol of a community's commitment to preserving its heritage and nurturing its future.

Two ventilation and service buildings located at each end of the new platform 14 of Sydney's Central Station feature a stunning artwork that establishes a visual link between the historical and contemporary elements.

Designed by renowned Bundjalung artist Dr Bronwyn Bancroft, the artwork has been created by incorporating stained bricks into 216 precast panels. A modern interpretation of “Connection to Country”, titled 'Time Travellers’, the artwork features imagery resembling a serpent, symbolising one of the numerous creation stories passed down by First Nation's people for over 60,000 years.

The project is part of the $955 million transformation of the 117-year-old station, executed by Laing O'Rourke for Sydney Metro. It stands as one of the most extensive upgrades undertaken on Australia's busiest railway station in decades.

Waeger Constructions, a National Precast Master Precaster, manufactured the panels,

with the vibrant staining process handled by ECOTONE, a National Precast Industry Supplier member. The outcome has achieved a remarkably resilient and innovative finish… a visual effect that is reminiscent of glazed bricks in various colours.

Sarah Bachmann, CEO of National Precast, highlights that staining provides a contemporary yet durable alternative to painting, showcasing its versatility.

“The project at Central Station's new buildings exemplifies the application of staining, where inlaid bricks were stained. There are many other projects where the precast itself has been stained, which emphasises the broad use of this innovative technique in infrastructure development,” says Bachmann.

Ms Bachmann notes that staining, traditionally utilised for colour correction in brickwork and, more recently, in cast insitu concrete, has become a common practice in precast as well. It allows for stunning colour statements ranging from translucent and opaque to metallic finishes. The durability of staining makes it a valuable application, particularly when applied in the factory, maximising the advantages of off-site manufacturing for both infrastructure and building projects.

The use of staining on precast, much like in brickwork, serves the purpose of colour correction by penetrating the surface. When harnessed to its maximum capability, staining has the ability to produce vibrant, naturallooking colours that harmonise seamlessly with the concrete, delivering an authentic appearance surpassing that of paint.

retains its vibrancy for an extended period. As well, stains offer artistic flexibility, allowing for customised applications that create diverse effects, from translucent hues revealing the concrete's texture to more opaque tones for a solid colour.

Stained concrete offers increased resistance to fading from UV exposure due to weather conditions, making it a practical choice for both indoor and outdoor applications. Its low maintenance requirements and environmentally friendly formulations contribute to its appeal, making stained precast concrete a versatile and sustainable option for architectural and design projects.

“Staining precast provides a variety of benefits that enhance both aesthetic appeal and durability. In this instance, the final outcome delivers a wonderfully pleasing aesthetic that also tells a story. At the same time, it has incorporated the off-site manufacturing efficiencies and durability that are inherent in precast concrete construction,” Bachmann concludes.
