AIQS Instrumental In Creating Standard For NSW Government Developments

The NSW Government has introduced a new, simpler and more transparent way to estimate development cost (EDC).

The NSW Government has introduced a new method to estimate the cost of developments for Council Applications with an Estimated Development Cost (EDC) over $3 million to be accompanied by an EDC report prepared by a Certified Quantity Surveyor (CQS).

AIQS CEO Grant Warner explains “We worked closely with NSW Planning to ensure that this process of estimating the development cost is enhanced to improve transparency and accuracy. The outcome is the AIQS Practice Standard: Construction Cost Assessments for NSW Estimated Development Cost Reports.”

The new process was created in response to the Independent Commission Against Corruption’s Operation Dasha Report, which recommended changes to improve transparency and to reduce

the risk of corruption.

“Utilising the services of a Certified Quantity Surveyor (CQS) is imperative for optimising outcomes and minimising risk on construction projects.” says Grant Warner.

A spokesperson for NSW Planning stated, “The Independent Commission Against Corruption (ICAC), found that existing methods for determining fees and planning pathways were vulnerable to manipulation. This was because calculating the cost of a development using capital investment value and cost of development is a complicated task, with many variables. The complexity created inconsistencies and made it hard to verify results.”

“The department determined that a single cost definition would reduce opportunities for manipulation. This gives us a simple, verifiable method to calculate development cost for all purposes.”

CSE24 SPEAKER LINE-UP INCLUDES:

• Peter Price, Chief Engineer, Energy Queensland

• Gillian Cagney, President - Australia & New Zealand (incl PNG & Mongolia), Worley

• Marghanita Johnson, CEO, Australian Aluminium Council

• Prof Bruce Mountain, Professor and Director, Victoria Energy Policy Centre

• Dr Jake Whitehead, Chief Scientist, Electric Vehicle Council

Apartment Construction Must Double To Build 1.2 Million Homes

According to HIA Chief Economist, Tim Reardon, the volume of apartments commencing construction will need to double to achieve the Government’s target of 1.2 million homes over the next five years.

“Unfortunately, due to ongoing capacity constraints will apartment commencements remain at exceptionally low levels for at least another year,” Tim Reardon said.

HIA released its Economic and Industry Outlook report during May. The report includes updated forecasts for new home building and renovations activity nationally and for each of the eight states and territories.

“With current policy settings, is anticipated that it will take at least six years to build 1.2 million homes,” added Mr Reardon.

“The volume of multi-unit commencements has fallen to almost half the volume commenced in 2016, before the impact of taxes on investors took effect. More recently, apartment construction has also been constrained by labour and material shortages and cost. This appears likely to continue for another year.”

“In the face of taxes on foreign investors, rising costs and longer build times, a significant volume of high-rise apartment projects will remain on the shelf,” he added.

“For many projects, this will require refinancing and then reapproval which will necessitate higher construction costs due to changes to the National Construction Code. This will further delay commencement for several years.”

“The subsequent shortfall in supply over the next few years will be observed in extremely low

rental vacancy rates and extra ordinary growth in rental prices,” Mr Reardon said.

“Competition for inputs remains intense against other sectors including non-residential construction and mining. This is occurring amid continued spending on public infrastructure projects, which is crowding out the home building, especially the high-rise apartment sector.”

“On the other side of the market, the outlook for detached house commencements appears set to reach a trough in the second half of 2024. From this low point, the recovery in detached home construction will be slow and inconsistent across the jurisdictions, with the major markets of New South Wales and Victoria faced with the challenge of a high cost of land, taxes and changing migration patterns.”

“Policy decisions at a state and local level will be a strong influence on the recovery of detached house building. The market has been driven by global factors over the past three years, and as these factors erode, it will be policies at a more local level that will determine the cost of delivering a new home to market,” he said.

“There are significant economic growth opportunities for regions that increase the supply of homes, which will have a catalytic impact on broader economic activity. This low volume of home building will occur amid pent-up housing demand and low unemployment levels that further drive demand. A rise in established home prices will make building a new home increasingly attractive despite the headwinds of higher interest rates.”

DETACHED HOUSE COMMENCEMENTS:

There is forecast to be 95,380 detached homes that will commence construction in 2023/24, down by 13.4 per cent compared to the previous year and down by almost a third on the 2020/21 peak.

This will mark the trough of the cycle and the weakest financial year in more than a decade. A weak recovery is expected in the year after, to 97,770 in 2024/25, before exceeding 110,000 by 2026/27.

MULTI-UNIT COMMENCEMENTS:

Multi-units are forecast to produce a 2023/24 financial year total of 64,350, up by 2.0 per cent compared to the decade trough of the previous year. An increase in unit commencements is anticipated to see 78,280 multi-unit commencements in 2024/25 as high rental prices drive lower density unit commencements. A further 93,480 in 2025/26. From 2026/27 starts will remain around 100,000 per year as the positive impact of the Olympics, institutional investors and build to rent projects begin to have a tangible impact on the volume of supply.

“It is possible to build the Australian Government’s target of 1.2 million homes over the next five years, but it will require significant lowering of taxes on home building, easing pressures on construction costs, and decreasing land costs. Even if this volume of homes is commenced, the housing shortage will remain,” concluded Mr Reardon.

City Of Melbourne Commits To More Affordable Homes

The City of Melbourne will continue to do its part to help tackle the housing crisis in Melbourne through a proposal to transform two Councilowned sites into new affordable housing.

Council’s Affordable Housing Strategy sets an ambitious target to deliver up to 25 per cent of affordable housing on Council land to address the current shortfall of over 6,000 affordable homes across the city, which is set to increase to 23,000 by 2036.

About 2,600 square metres of land is proposed to be converted into multi-unit affordable housing on Curzon Street in North Melbourne and Victoria Street in West Melbourne, which could include provisions for key workers, Aboriginal peoples and older women.

A further $1.5 million will be invested in Council’s draft Budget 2024–25 to provide the City’s most vulnerable community members with the support they need through frontline services.

The Curzon and Victoria streets projects acknowledge the City of Melbourne’s commitment to providing affordable housing for key workers, who are employees required to attend their workplace and are generally low-tomiddle income earners.

The City of Melbourne has more key workers than anywhere else in Victoria, approximately 142,000 - almost a quarter of whom travel more than 30 kilometres to work.

Community consultation on the proposal is currently underway. If approved, Council will appoint a community housing provider to develop the sites.

“Melbourne is in a housing crisis – every home that becomes available matters,” said Lord Mayor Sally Capp.

“This draft Budget is about doing what counts and delivering on our promises to the community – delivering truly affordable homes, particularly for key workers.”

“Returning to a surplus budget in 2024-25 allows future Councils to continue to make important investments that will better people’s lives,” the Lord Mayor added.

“More key workers are employed in the City of Melbourne municipality than anywhere else in Victoria. Thousands of these invaluable workers are travelling more than two hours each-way –they deserve affordable housing close to their place of employment.”

“We’re working to transform three Councilowned sites to give more Melburnians a place to call home, while creating new pathways

out of homelessness for our most vulnerable community members,” Lord Mayor Capp said.

The sentiments were echoed by Deputy Lord Mayor Nicholas Reece, who said that “…as a local government, we’re doing everything we can to increase the number of homes available for residents, students and key workers – with an ambitious affordable housing program with design excellence at its core.”

“We’re planning to turn land the size of 10 tennis courts into affordable housing in North and West Melbourne – and we’d love for the community to have their say on our proposal,” the Deputy Lord Mayor said.

Vital frontline services will be boosted by more than $1.5 million for Council’s key contracted specialist homelessness services – including Launch Housing’s on-street daily support team, the Salvation Army’s after-hours safe space, and specialist youth homelessness support through Melbourne City Missions’ Frontyard Youth Services.

Construction of the City of Melbourne’s landmark Make Room project will be completed in August, which repurposes a Council-owned building at 602 Little Bourke Street into transitional supported accommodation.

The facility will include 50 studio apartments, housing and homeless services and other wraparound support for those who need it most. Council has secured $16.1 million from the Victorian Government and philanthropic sector for the project to date.

City of Melbourne’s Health, Wellbeing and Belonging portfolio lead, Councillor Dr Olivia Ball, said:

“Access to safe and secure housing is a fundamental human right, and solving the housing crisis is about more than just building.”

“We know the value of investing in frontline services to help more people at risk of or experiencing homelessness – that’s why we’ll continue to work alongside partners to make a real difference on the ground,” Councillor Ball concluded.

Australian Engineering Skills Gap Is Double Global Average

New analysis from global employment specialist Randstad has revealed that 4% of all Australian engineering and maintenance jobs are currently vacant - against a global industry average of 2.1%.

The skills with the highest vacancy rate in Australia are:

Salaries are being driven up in part by this skills shortage, with Australia offering the fourth highest salaries for the skills globally, with an average salary range of $72k to $138k - 11% higher than the UK.

While Australia has stronger female representation in the industry when benchmarked against key players like the US and UK, more must still be done to close the sector gender gap with men currently accounting for 71% of all engineering and maintenance talent.

Clayton Colbert, National Director of Construction, Property & Engineering at Randstad comments: “It's around twice as challenging to find the right engineering or maintenance talent than the global average. They tend to be less mobile and are usually required on site, generally making it harder to access new talent pools. So, rather than fighting talent scarcity in their local market, businesses struggling to recruit should look to relocating talent within the field.”

“Employer branding is a key piece to this puzzle. To attract interstate or international staff, they need to compete on salary as well as nonpecuniary benefits, culture, and work-life balance,” he concluded.

ABOUT RANDSTAD

Randstad was founded in 1960 and is headquartered in Diemen, the Netherlands. It currently operates in 39 markets, and 2022 helped more than 2 million people find a job and advised over 230,000 clients on their talent needs.

The company employs more than 40,000 people and generated revenue of €27.6 billion in 2022

THE (NOT SO) NEW KID ON THE BLOCK

Leading global construction chemicals company MC-Bauchemie expands its presence in Australia

While it’s fair to say that most construction industry professionals across Australia may not be immediately familiar with the name MC-Bauchemie, many of the company’s world-leading products have been specified and used in countless Australian projects, including many major projects, for over two decades. Indeed, over the past 20 years, MC-Bauchemie (or MC as it is generally known) products have gained an enviable reputation for quality, performance and reliability, are widely considered ‘the products of choice’ by an ever-increasing number of engineers, specifiers and contractors – particularly across the tunnelling and infrastructure construction and maintenance sectors.

From injection resins, repair materials and waterproofing membranes for tunnels, through to specialist repair mortars, highdensity surface coatings, and acid and chemical-resistant protection and repair systems for sewers, treatment plants and other heavy industrial facilities, demand for products from MC’s Infrastructure & Industry range has skyrocketed in recent years. So much so, in fact, that products such as MC’s flagship MC-Injekt GL-95 TX injectable acrylate gel waterproofing sealant is now specified and used in the majority of road and rail tunnels up and down Australia’s east coast.

With the ever-increasing demand for its products, MC took the opportunity in 2023 to expand its Australian and New Zealand operations, through the establishment of MC-Bauchemie Australia Pty Ltd. Headed up by Managing Director Jason Bolt, MC Australia aims to expand its business and brand awareness in the Australian market, with products that have been specifically developed to meet the needs of the Australian construction and maintenance industry.

“While MC products have been used with great success for more than 20 years on projects across Australia, including many of the country’s largest ‘flagship’ infrastructure construction and maintenance projects, the fact that MC didn’t have a business presence in Australia meant that we didn’t really have a brand profile outside of those projects,” Jason Bolt commented.

MC has been working in the background for some time in the Australian market, partnering with key, suppliers for unique sustainable solutions. For example, MC has been working with Wagners Concete on Geopolymer concrete for commercial projects in Australia and abroad, including the massive Toowoomba Wellcamp Airport project in Queensland.

“MC products have gained a reputation for quality, sustainable innovation and performance across an array of projects. This has not only resulted in a steady increase in demand for products from our Infrastructure & Industry range, it has also sparked a lot of interest in products from our other business sectors, particularly our Concrete Industry products, including admixtures, curing and release agents, and our concrete cosmetic products,” he added.

BCS SUPPLY BUSINESS ACQUISITION

While MC products had previously only been available in Australia through its licensed distributor and applicator Building Chemical Supplies (BCS), in late-2023 the then newly formed MC-Bauchemie Australia business reached an agreement with BCS to acquire the assets of its building chemicals trading business - effectively separating the supply and applications businesses.

Jason Bolt explained: “BCS has been a major distributor and applicator of MC products in Australia for nearly twenty years, and the two companies have always enjoyed a strong, cooperative partnership. However, MC has many technologies beyond what was being offered, and with the focus in Australia on sustainability, total cost of construction and innovative construction materials, we believed it was the right time for MC to enter the Australian market directly.”

“By separating the materials supply and application businesses, this acquisition provides both companies with the ideal opportunity to continue working together, while focusing on our individual strengths and further developing our core businesses,” Jason Bolt added.

As part of the acquisition, several BCS sites, including warehouses in the Sydney and Melbourne region, were transferred to MC Australia. MC Australia will also be opening additional offices and warehouse facilities across Australia and New Zealand throughout 2024 and beyond.

The acquisition of the trading business also saw seven BCS employees transfer to MCBauchemie Australia. As well as highlighting the spirit of cooperation and quality of the long-term relationship that exists between the two companies, having the BCS employees join the team at MC Australia means that for BCS customers, the acquisition was as close to ‘seamless’ as possible.

Dan McGown, National Technical Manager – Tunnelling, commented: “From a customer perspective, it also means that there is seamless continuity of both product supply and services, which is critical – particularly on major projects.”

“Customers will have no interruptions in service or material supply, no loss of critical ‘local’ and project-based knowledge, or for that matter, in most instances, no change in people they’re dealing with,” Dan said.

SIX DECADES OF INNOVATION

Founded in the German city of Essen in 1961 by Heinrich W. Müller, MC-Bauchemie was established to serve rapidly developing market for ready-mix concrete and precast components – more specifically, the development and production of innovative concrete and mortar admixtures to meet the needs of Germany’s rapidly growing highway and subway infrastructure construction sector.

Not surprisingly, the company’s focus on innovative products, coupled with Dr Müller’s motto “Business is done between people, not companies”, saw a significant growth in demand for its products in a relatively short time. Indeed, by 1962, a little over a year after its establishment, MC was already producing to capacity at its Essen facility, and a new long-term solution to allow expansion was sought.

In 1963, MC-Bauchemie moved to its newly constructed facility in the nearby town of Bottrop, where it is headquartered to this day – albeit on a much larger scale!

From its earliest days, MC-Bauchemie products have been associated with reliability, quality, innovation and, of course - in keeping with the company’s motto “Be sure. Build sure.” – safety in construction. Over the past six decades, this third-generation family owned company has developed from an ambitious business with 25 employees, to a leading international manufacturer of construction chemicals, producing innovative solutions for the treatment,

curing and hardening of concrete, as well as for the protection and maintenance of buildings, tunnels and underground structures.

The group of companies now employs more than 2,500 people, has more than twenty R&D and production facilities across several continents, and a presence in over 40 countries worldwide.

The company’s operations are organised into three key market segments, namely:

• MC for Concrete Industry: incorporating high quality concrete and mortar admixtures, curing and release agents, and concrete cosmetic products;

• MC for Infrastructure & Industry: incorporating protection and repair systems for engineered structures and industrial builds, including repair mortars, surface protection coatings, waterproofing injection and joint sealing systems; and

• MC for Buildings: specialised product systems for the sealing, protection and repair of commercial and residential buildings, including high-efficacy bituminous and bitumen-free waterproofing systems, super-resistant, high-performance coatings for floors, walls and ceilings, together with high performance screed systems, plasters, renders and mortars. The MC for Buildings portfolio also incorporates a separate selection of speciality product systems specifically designed for the restoration and repair of heritage buildings.

ONGOING COMMITMENT TO R&D

Three generations on, this family-owned business maintains its commitment to innovation, safety and sustainability, working with its customers around the globe to find the best solutions to meet the needs of their specific construction challenges.

Importantly, for MC, this commitment is much more than a simple ‘marketing tagline’. In fact, 10 % of MC’s global workforce is in the Research and Development department – a massive commitment by any measure.

“We regard construction as a serious matter,” Jason Bolt said. “We recognise that each product can play a crucial role in ensuring the integrity both of a whole structure and of any repair work done on it.”

Dan McGown added: “Choosing the wrong material or using it incorrectly can lead to damage in building components and in extreme cases, it may even endanger life. That is why we take such care with each and every project, and every product.”

“We combine the expertise of mineralogists, concrete technologists and materials scientists from our in-house laboratories with the knowhow of our construction engineers and specialist advisers assigned to sites around the world. Maintaining short communication paths, these experts work together wherever required in order to find the most appropriate solution to the specific tasks facing planners, contractors and clients,” he said.

As well as expanding the company’s existing Infrastructure & Industry product offering, as part of its Australian expansion, MC will also be introducing its world-renowned Concrete Industry product range to the Australian market for the first time.

With products to enhance a range of performance characteristics in concretes and mortars, including early and final strengths, compaction, resistance to damage, surface quality and ease of placement, the MC Concrete Industry range includes a selection of specialist admixtures for both the ready-mixed and precast concrete sectors. It also includes a range of curing compounds to protect freshly poured concrete during the hydration process, releases agents to optimise the off-form finish of both precast and poured insitu concretes, and concrete cosmetic products to rework, repair and match any damage that may have occurred to precast concrete components either onsite or in transit.

“We’re very excited to be able to provide products from the Concrete Industry range direct

to our Australian customers for the first time,” Jason Bolt said.

“Importantly, while these products have been well and truly proven in countless projects around the world, our team here in Australia are also testing and assessing each admixture formulation to ensure that it performs as specified in Australian conditions and using locally sourced construction materials."

"While it means we can’t simply ‘open up shop and have all our products available from day one’, we believe that this testing and assessment is a critical step when introducing new products to a new market,” he said.

“After all, despite the fact that they’ve been used around world for over six decades, for most customers here in Australia, these admixtures will be completely new to them. Having each of the products tested and assessed under Australian conditions provides our customers with the confidence that when they use our admixtures they will perform exactly as specified and deliver the results they expect,” Jason concluded.

INTRODUCING THE CONCRETE INDUSTRY RANGE TO THE AUSTRALIAN MARKET

EASY GRAFFITI REMOVAL

It’s not only Local Government that’s stuck with the problem of cleaning off the artwork of graffiti artists. Factories, commercial buildings, even retailers in shopping centres can be the targets for this age-old issue. One solution that presents a flexible and chemical free way of removing graffiti safely and efficiently is pure steam!

Leaders in the pressure cleaning industry, Aussie Pumps, recommends using a 4,000 psi steam cleaner like their Heatwave because the steam literally peels paint off walls. This means you can carry out graffiti removal without the need for carcinogenic cleaning chemicals or dangerous caustics.

The steam cleaners can also be used for a myriad of council jobs that include cleaning amenities, sanitising park tables and benches, removing chewing gum, even melting the grease off public BBQs. They also fulfil a useful role cleaning public spaces like car parks or piazzas where spilled food or even oil stains can be removed without the use of cleaning fluids.

AUSSIE’S HEATWAVE SOLUTION

The Aussie Heatwave is a Honda petrol-driven 4,000 psi high pressure steam cleaner which delivers steam up to 130°C. The 13HP electric start Honda engine drives a heavy duty triplex pump with solid ceramic pistons and top quality seals for a long trouble free life.

The Heatwave features a 12 volt ignition system and a diesel fired burner. The heating system enables the operator to go from using cold to hot water with the press of a button. The operational temperature of the water delivered can be dialled up from ambient to 130°C.

The unit is built into a compact stainless steel frame with four steel wheels and rubber tyres. This means it can be used as a mobile wash unit in difficult to access locations. Alternatively, it can be hard mounted on a ute, truck or trailer together with a 300 or 400 litre water tank to become a self-contained mobile high pressure cleaning system.

Aussie invites all users of pressure cleaners, irrespective of brand, to complete the course online at https://aussiepumps.com.au

LABOUR SAVING ACCESSORIES

The use of high pressure accessories can improve cleaning efficiency even further. For example, high pressure reels can either be fitted to the machine or, if it’s part of a mobile cleaning system, bolted to the deck of a vehicle. Using a hose reel to mount extra-long hoses adds operator convenience and reduces hose wear and trip hazards.

When using cold water, a turbo lance for the gun has the effect of multiplying the effectiveness of the pin jet which can halve cleaning times, saving on labour costs. The turbo is a rotating turbine, mounted in the end of the lance, that multiplies the impact of the water jet going through as it spins under pressure.

A flat surface cleaner is ideal for cleaning large flat areas with streak free results. Flat surface cleaners can cut cleaning times by up to 75%, use less water and save on fuel and wear of the machine.

A drain cleaning kit - a portable Mini Reel fitted with 60 metres of sewer hose and drain cleaning nozzles - enables hot water (up to 80°C) under pressure to be used to clear grease traps, blocked drains and even sewer lines.

GET HOME SAFE

Australian Pump Industries offer a free Safe Operator online training course. The course is available to Councils, cleaning contractors, graffiti specialists and virtually anybody who professionally uses a pressure cleaner of any brand. The course is informative and makes high pressure pump technology easy to understand. Australian Pump want operators to be safe and their practical online course makes it easy.

Further information on Aussie’s complete range of high pressure cleaners in both hot and cold versions is available from Australian Pump Industries. Call (02) 8865 3500 or visit the website: https://aussiepumps.com.au

TESTING IGU’S FOR QUALITY, PERFORMANCE AND COMPLIANCE WITH AS 4666

Insulated Glass Units, or IGU’s, are the manufactured glass unit that forms the glass component in a double-glazed window. Energy compliance of buildings becomes more important as Australia moves towards efficient use of electricity, and insulating the entire house becomes paramount.

Windows and doors form a large part of most building envelopes; therefore, insulation is important. Normal clear monolithic glass offers very little insulation value, allowing heat or chilly weather to affect the internal environment of a building, requiring air conditioning or heating to ensure comfort levels inside the building - driving up energy usage.

IGU’s are placed in the weathering cabinet for 15 weeks with temperatures cycling between -18° to 57°C and 95% humidity.

HOW DO YOU KNOW THAT YOU HAVE COMPLIANT IGU’S THAT WILL OFFER LONG TERM CLEAR VISION AND GOOD INSULATION VALUE?

Azuma Design type tests IGU’s to the long-term requirements of Australian Standard AS 4666 “Insulating Glass Units” which ensures good manufacturing practices have been used to produce good IGU’s that will last for many years, providing great insulation.

The sample IGU’s are placed in an accelerated weathering cabinet for 15 weeks. Azuma then tests the moisture content of products before weathering and post weathering of the samples provided for testing. If the moisture content has increased significantly post testing, this will result in a failure, also indicating to the manufacturer that they need to correct their manufacturing practices before they are issued a compliance certificate.

Great IGU’s need to have both their primary and secondary seals applied correctly for longevity, thereby ensuring no moisture can penetrate to the internal gap between the windows. If these seals fail, moisture will penetrate, ruining the integrity of the IGU, decreasing the insulation value of the IGU and possibly the visual aspect allowing fogging in the internal gap.

A lot of IGU’s have argon gas filling in the gap between the two glass panels, which provides for a 10 to 15% insulation improvement. If the seals fail this gas escapes, reducing the insulation value the IGU provides, meaning the building envelope is compromised.

Azuma’s testing capabilities ensures the IGU’s presented for type testing have been manufactured correctly. This should ensure the manufacturing of all IGU’s from a supplier are of great quality. If the IGU’s pass the long term testing requirements of AS 4666, then the product is fit for purpose and installation in your building. This means that the product then is ideal to meet the comfort levels we expect over the useful life expectancy, while installed in the building.

Manufacturers are required to type test there IGU’s every 2 years when purchasing double glazed windows, ensure that the product purchase has been accredited.

NEW MODEL MAKES IT EASIER TO BUILD SUSTAINABLE STRUCTURES OF TEXTILE-REINFORCED CONCRETE

By reinforcing concrete with textiles instead of steel, it is possible to use less material and create slender, lightweight structures with a significantly lower environmental impact.

The technology to utilise carbon fibre textiles already exists, but it has been challenging, among other things, to produce a basis for reliable calculations for complex and vaulted structures. Researchers from Chalmers University of Technology, in Sweden, are now presenting a method that makes it easier to scale up analyses and thus facilitate the construction of more environmentally friendly bridges, tunnels and buildings.

“A great deal of the concrete we use today has the function to act as a protective layer to prevent the steel reinforcement from corroding. If we can use textile reinforcement instead, we can reduce cement consumption and also use less concrete − and thus reduce the climate impact,” says Karin Lundgren, who is Professor in Concrete Structures at the Department of Architecture and Civil Engineering at Chalmers.

Cement is a binder in concrete and its production from limestone has a large impact on the climate.

By using alternative binders instead of cement, such as clay or volcanic ash, it is possible to further reduce carbon dioxide emissions. But so far, it is unclear how well such new binders can protect steel reinforcement in the long term.

“You could get away from the issue of corrosion protection, by using carbonfibres as reinforcement material instead of steel, because it doesn't need to be protected in the same way. You can also gain even more by optimising thin shell structures with a lower climate impact,” Lundgren said.

In a recently published study in the journal Construction and Building Materials, Karin Lundgren and her colleagues describe a new modelling technique that was proved to be reliable in analyses describing how textile reinforcement interacts with concrete.

“What we have done is to develop a method that facilitates the calculation work of complex structures and reduces the need for testing of the load-bearing capacity,” Ms Lundgren added.

One area where textile reinforcement technology could significantly reduce the environmental impact is in the construction of arched floors. Since the majority of a building’s climate impact during production comes from the floor structures, it is an effective way to build more sustainably. A previous research study from the University of Cambridge shows that textile reinforcement can reduce carbon dioxide emissions by up to 65 percent compared to traditional solid floors.

A textile reinforcement mesh consists of yarns, where each yarn consists of thousands of thin filaments (long continuous fibres). The reinforcement mesh is cast into concrete, and when the textile-reinforced concrete is loaded, the filaments slip both against the concrete and against each other inside the yarn. A textile yarn in concrete does not behave as a unit, which is important when you want to understand the composite material's ability to carry loads. The modelling technique developed by the Chalmers researchers describes these effects.

“You could describe it as the yarn consisting of an inner and an outer core, which is affected to varying degrees when the concrete is loaded. We developed a test and calculation method that describes this interaction. In experiments, we were able to show that our way of calculating is reliable enough even for complex structures,” Ms Lundgren concluded.

The work together with colleagues is now continuing to develop optimisation methods for larger structures.

SWEDISH CONCRETE MANUFACTURER LAUNCHES LOW-EMISSION HYBRID WALL

The Swedish concrete element manufacturers Heidelberg Materials Precast Contiga and Metsä Wood have developed a hybrid wall element with a lower carbon footprint than conventional concrete wall elements. Now, the element solution is ready for use in real construction projects.

“We are experiencing increased demands from our customers for environmentally smart solutions. The idea is that this serves as a great addition to our portfolio,” says Daniel Eriksson, Division Manager at Heidelberg Materials Precast Contiga.

The hybrid wall element is a facade element in a sandwich construction, featuring an outer layer made of climate-improved concrete, intermediate insulation, and a load-bearing inner panel made of strong and material-efficient laminated veneer lumber, Kerto® LVL. The element has approximately 30-50% lower climate impact compared to an equivalent traditional concrete sandwich element, and it is significantly lighter, which also affects the overall climate impact of the entire construction project.

“Transportation to the construction site can be reduced because we can transport twice as many elements in the same shipment,” explains Daniel Eriksson.

Precast Contiga manufactures steel frames and concrete elements in factories located in Norrtälje and Uddevalla. Nearly two years ago, the company

initiated discussions with Metsä Wood to start manufacturing hybrid elements for the Swedish market. Since the company typically works with steel and concrete, this endeavour required learning about how wood functions.

“The production method is very similar to what we already have, so we can create these hybrid elements using the same approach as our other walls, and they are assembled in the same way. We haven’t made any major investments or modifications,” says Daniel Eriksson.

“The European Union aims to be climate neutral by 2050, and the construction industry can contribute significantly to reach this target and we’re experiencing a demand for climate-smart solutions from the construction industry,” says Håkan Arnebrant, Business Development Manager at Metsä Wood.

“One of the advantages of this hybrid element is that construction contractors do not have to change their way of building with concrete elements but can still lower their carbon dioxide emissions.”

“At the same time, the walls can be made 50–75 millimeters thinner than walls built with concrete elements, which can give quite a few extra square meters in a building,” Mr Arnebrant added.

To practically test how the hybrid wall functions, a real house has been constructed on the factory premises in Norrtälje using these new elements. The

test building is equipped with moisture sensors to monitor what happens inside the wall elements, and so far, no moisture has been detected. Additionally, various solutions for installations have been tested within the building.

The hybrid wall element is particularly suitable for buildings with up to five floors. These can include residential buildings, offices, healthcare facilities, or schools.

“Here, it’s a truly excellent product that we are now ready to test in real projects,” says Daniel Eriksson. “This innovative hybrid wall represents a promising step toward more sustainable construction practices.”

AWARD-WINNING DESIGN AND CONSTRUCTION: TRYP BY WYNDHAM ADELAIDE

Following the pandemic's challenges, South Australia has seen a resurgence in tourism activities, with a bustling events calendar, the reinstatement of cruise ship stops, and improved air travel links.

“Adelaide has been calling out for more accommodation because capacity is often exceeded when we have events. There's been a shortage of hotels here for some time, especially with major events like the Adelaide Fringe,” explained Daryl Crebbin, General Manager, Marshall & Brougham Constructions.

The construction of TRYP by Wyndham Pulteney Street Adelaide is timely, poised to cater to the increasing influx of visitors seeking to explore the region's cosmopolitan culture and rich history in arts and festivals.

Suspended slabs for TRYP by Wyndham Pulteney Street Adelaide were designed using Fielders' KingFlor® KF70® Formwork System.

TRYP by Wyndham marks a significant milestone as the introduction of the TRYP by Wyndham brand to Australia. This 120-room property exemplifies contemporary design and urban energy, with architecture that echo the city's vibrant lifestyle. Its city location offers guests easy access to Adelaide's rich tapestry of multicultural restaurants, lively bars, decorated laneways, and the boutique shopping experience of Adelaide Central Markets and Rundle Mall.

Central to its construction was the integration of Fielders KF70® steel formwork system, a testament to the industry's shift towards more efficient, lightweight construction methodologies.

NAVIGATING SITE CONSTRAINTS

From the outset, the TRYP by Wyndham Pulteney Street Adelaide project was faced with site constraints, primarily due to the proximity of existing buildings that bordered the construction area.

“There were some challenges on site as there were existing structures at north and south where we need to ensure no damages due to the excavations or piling therefore, underpinning and temporary supports were applied,” said Samir Hanna, Principal Structural Engineer, MLEI.

To circumvent these challenges, the project team decided on a different approach to traditional propping.

“One of the solutions was to not have propping for the formwork and that's why a steel frame structure with the steel formwork system was used,” said Daryl Crebbin.

MLEI, the project design engineers, chose to use a known Fielders solution. “We designed the suspended slabs with KF70® formwork to avoid the requirement for propping” explained Samir Hanna.

This decision, alongside the use of eco-friendly materials and unique finishes, expedited the construction process, added to the building's distinctive aesthetic, while also reducing costs.

ABOUT FIELDERS

Fielders has been supplying the Australian building and construction industry with a range of quality steel building products for over 115 years.

Fielders manufactures an extensive range of steel building products and solutions including KingFlor® composite steel formwork, FreeForm™, ARAMAX® and Finesse® roofing and walling systems, Endurance® sheds and structures, Centenary® patios, carports and verandahs and Dominator® fencing and screening.

FIELDERS' KINGFLOR® KF70® FORMWORK SYSTEM

Fielders’ KF70® system has been recognised globally as a cost-effective composite steel formwork solution, preferred for its longer span capabilities and deeper profile compared to other formwork options

“A key advantage of using the KF70® system is its ability to reduce the weight of the building,” explained Ashesh Singh, BDM - Engineering of South and Western Australia, Fielders.

“This is achieved through the unique profile of the decking, which displaces a certain amount of concrete.”

“The KF70® system displaces 26 millimetres of concrete by volume compared to a standard concrete slab. Opting for the KF70® system results in a lighter slab, which in turn requires a lighter foundation. This reduction in weight and material use offers significant benefits, both financially and structurally, to builders and property owners alike during construction,” Ashesh Singh added.

With features like SquashCut™ ends and availability in pre-cut lengths with a 600mm wide cover, KF70® significantly accelerates the installation process, making it an ideal choice for large-scale projects like TRYP by Wyndham Pulteney Street Adelaide.

“The good thing about KF70® is that you can get larger spans with it, needing to use

a bit less concrete, and it’s a strong profile,” said a representative of Structural Systems, an Adelaide-based consulting engineering company, who were involved in the substructure and undertook inspections to ensure compliance during construction.

The installation process of the KF70® system was smooth and efficient, leading to substantial savings in concrete, supporting framework, and foundation load costs.

“We have a good relationship with Fielders and they always provide technical advice and support,” commented Samir Hanna.

“One thing I can say about Fielders and the formwork is that the deliveries were timely and always reliable in that regard,” Daryl Crebbin said.

CONCLUSION

The TRYP by Wyndham project exemplifies the seamless integration of advanced construction technologies, notably Fielders KF70® steel formwork system, to address the evolving demands of the global hospitality industry.

This collaboration between engineers, architects, and Fielders has resulted in a development that elevates modern construction benchmarks, setting a new standard for hospitality facilities in Adelaide and further afield.

The KF70® system displaces 26 millimetres of concrete by volume compared to a standard concrete slab, resulting in a lighter slab, which in turn requires a lighter foundation.

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 AS 5100.2:2017.

What’s more, at around 80 kg/m installed, DOLRE bridge tra c barriers are significantly lighter than many AS 5100 ‘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 AS 5100:2017 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 an impact to a fraction of the bridge deck's capacity, thereby minimising the risk of damage to the bridge deck and structure during an impact.

DOLRE bridge tra c barriers can help to extend the serviceable life of many existing bridges - delivering AS 5100 and AS 3845 compliant protection without the need for expensive deck strengthening works or additional reinforcement. DISCOVER MORE

LIGHT GAUGE STEEL SUPPORTS INSPIRED FACADE DESIGN

ADDRESS: Grattan Street, Prahran

Situated in Prahran overlooking the Grattan Gardens, this multi-residential development with its skilfully raked facade delivers far more than a building in harmony with its surroundings.

By utilising light gauge steel framing made from TRUECORE® steel for the facade’s structure, the following benefits were realised:

• Engineered Precision

The facade frame made from TRUECORE® steel was fabricated to fine tolerances to structurally support and accommodate the roof tiles, and specialised flashing system that channels waterflows around the windows and down the facade. [PB]

• Efficient Construction

The fully engineered facade solution was prototyped and tested prior to prefabrication. The thorough detailing completed during the design phase, coupled with the exact tolerances achievable with prefabrication, resulted in the smooth installation of the facade system at site. [AS]

• Lightweight yet strong Collaboration between contractors, delivered a facade frame with the structural adequacy to support the significant weights of roof tiles and the protruding windows. [PB, AS]

PROJECT HIGHLIGHTS

Situated in the Melbourne suburb of Prahran, amongst heritage cottages and cafes and across from Grattan Gardens, this striking multiresidential development blends artfully into its surroundings. The sloping facade, tiled in hues of green gently pulls away from the street, allowing it to sensitively harmonise with the park around it. The windows that punctuate the facade’s design, capture views of the surrounding environment, and allow light to fill the internal spaces.

The appointed builder, Cobild, not only delivered on the design intent of this facade but enhanced it with the clever selection of cladding material and the structure required to support it. The façade design originally called for the use of hot-rolled structural steel with a glass-fibre reinforced concrete skinned cladding (GRC).

With the desire to improve the facade’s enduring visual appeal and serviceability, Cobild recommended that the facade structure was changed to that of a structurally engineered LGS frame, designed to support roof tiles as well as the distinctively large windows.

Varying in colour from deep forest greens to lighter turquoise, the skilful blending of the high gloss imported tiles delivers an intensity of colour that heightens the visual interest of the facade’s finish. However, the modularity and weight [70kg per m²] of the imported terracotta tiles also added to the design complexity, and the demand on the facade structure underneath.

Lightweight yet strong, LGS structural framing made from TRUECORE® steel was the material of

choice for the facade structure. Utilising almost 13,000 lineal metres of TRUECORE® steel, Bolt Blue Constructions and Dynamic Steel Frame collaborated with the facade engineers to deliver a facade frame with the structural adequacy to support the significant weight of the roof tiles and the protruding windows [some up to 300kgs].

With the window reveals protruding above the face of the tiled facade, a specialised flashing system was required to ensure waterflows were channelled around the windows and down the facade. The LGS facade made from TRUECORE® steel was fabricated to fine tolerances to both structurally support and appropriately accommodate these flashings. Leaving nothing to chance, a prototype of the window details was designed, manufactured and tested prior to full scale fabrication of the facade structure.

Post-tensioned concrete slabs were used at each level of the build, providing rigidity to the structure. Using over 800 brackets, and 1600 bolts, the LGS facade structure was then securely connected to these slabs using a method that allowed for slab deflections. The final facade structure was also designed so the battens could be appropriately installed at defined intervals to support the roof tiles.

Alex Solam from Cobild stated that, “…significant effort was required at the design stage to ensure the prefabricated LGS frames were consistent with the architect’s vision, performed structurally, and could be efficiently installed during construction.”

Given the uniqueness and complexity of the design, Dynamic Steel Frame spent many hours finalising the details of the fully engineered LGS facade structure prior to its manufacture. This commitment, coupled with the exact tolerances achievable with LGS fabrication, resulted in the efficient installation of the facade structure at site.

“Once familiar with the approach, the lightness and accuracy of LGS frames made for efficient installation. Using installers that specialise in LGS framing installation was also beneficial,” stated Alex.

“We under-estimated the design’s complexity at the start of the project, so it was pleasing to have such a successful outcome during construction,” stated Peter Blythe, Director of Dynamic Steel Frame.

SAFETY FOR HIRE

Trafquip expands its fleet of Scorpion TMAs with new Scorpion® II TL3 and Scorpion® METRO TL2 units

Building on its existing fleet of more than 40 Scorpion® Truck Mounted Attenuators (TMAs), leading Australian traffic equipment hire specialists Trafquip has recently taken delivery of two new Scorpion® TMAs, including its first Scorpion® METRO MASH TL2-rated unit. Trafquip has also entered into a major Impact Protection Vehicle (IPV) building program, which will see the company secure 1-2 new TMA’s per month over the next 12 months.

Speaking about the new Scorpion TL2 unit, Trafquip Managing Director, Jeff Trim, said that it represented a major step forward for the industry, especially in terms of recognising the importance of providing protection for workers from vehicular impacts in work zones along suburban streets and in areas with posted speed limits of 70 km/h or less.

“Accidents happen above 70 km/h and below 70 km/h, so it’s critical to provide protection for all stakeholders in all locations,” Jeff said.

“While the larger Scorpion II unit provides MASH TL3 certified impact protection for speeds up 100 km/h, it’s not always practical, or for that matter, even possible, to have a large TL3-rated Impact Protection Vehicle at every worksite – especially those located along narrow suburban streets or low-speed roads.”

“Now, thanks to the new Scorpion® METRO units, we’re able to provide our customers with a fully tested, certified and approved MASH TL2-rated Impact Protection Vehicle that has been specifically designed for use along streets and roads with posted speed limits of 70 km/h or less,” he added.

“The traffic management industry is developing at an extremely rapid rate. Even looking back over the past 10 years, it’s easy to see how far things have come. The industry is maturing, and compliance is improving – not only across major projects but also along smaller suburban and regional worksites,” Jeff said.

“With that in mind, we believe that the Scorpion TL2 TMA can play a major role in boosting safety for workers along low-speed suburban and rural roadwork zones, and as such, we’re expecting to see a significant increase in demand for these units from councils and contractors alike,” Jeff said.

DRY HIRE EQUIPMENT SPECIALISTS

Established in Brisbane in 2007, Trafquip started out as a specialist traffic management design and planning company, providing services for councils and contractors across Queensland.

Building on this knowledge and experience, the company expanded into ‘dry hire’ (e.g. equipment only / no operator) of traffic management fleet and equipment. From Truck Mounted Attenuators (TMAs) – also known as Impact Protection Vehicles (IPVs) – Cone Trucks, Super Utes, Traffic Control Utes, Civil Vehicles and Management Vehicles, through to Lighting towers, Portable Traffic Lights, Variable Message Sign (VMS) Trailers, Portabooms, and eSAS (Electronic Speed Awareness Signs), Trafquip has built an enviable reputation for the supply of high quality, well maintained and reliable equipment.

“I always say, we don’t do compressors, generators and that sort of equipment. We only do traffic management equipment, because that’s what we know and understand,” Jeff Trim explained.

“We believe that our understanding of the industry and the traffic management business is our major advantage. So, rather than trying to be a ‘Jack of all trades and master of none’, we focus on ensuring that we provide safe, well-maintained traffic management equipment solutions for our clients.”

Not surprisingly, the decision to focus purely on traffic management fleet and equipment, combined with the team’s extensive first-hand industry experience, saw a significant growth in demand for its services. Indeed, from its relatively humble beginnings, Trafquip now provides traffic management vehicles and equipment to clients in Queensland, New South Wales, Victoria, Northern Territory and South Australia.

The company’s main depot in Loganholme, south of Brisbane, incorporates a large mechanical workshop and dedicated manufacturing/ fabrication facility, with a separate auto-electrical service yard located on an adjacent property. Trafquip also operates a depot and maintenance facility in the Adelaide suburb of Elizabeth South.

FOCUS ON QUALITY AND SAFETY

Trafquip’s fleet of equipment now encompasses more than 650 units, including more than 40 Scorpion TMA-equipped Impact Protection Vehicles.

“Everything about us is about protecting stakeholders,” Jeff Trim said.

“First and foremost, we’re a safety business, and we try and reflect that in everything we do. Whether that’s introducing new equipment like the TL2 TMA to our fleet, or sponsoring the TMAA Young and Rising Stars traffic management award, our aim is to promote best practice traffic management, encourage industry professionalism, and maximise safety for all stakeholders.”

“That’s also why we choose Scorpion TMAs for our Impact Protection Vehicles. They’re well designed and built, they’re fully MASH tested and certified, and they’re well supported across Australia by A1 Roadlines.”

“Most importantly, they deliver proven life-saving protection for workers,” he said.

“That said, our customers have a lot of say in what we do in terms of equipment choices, and they also prefer the Scorpions. Scorpion TMAs have an excellent reputation for quality and reliability in the field, and when it comes to equipment, particularly hire equipment, that’s critical. Our customers need to know that when the equipment arrives on site, they’ll be able to deploy it quickly, without any issues.”

“Most importantly, when it comes to Impact Protection Vehicles, our customers need to be

QUEENSLAND’S FIRST MASH TL2 SCORPION® TMA

Mounted on a Hino 300 Series 616 Hybrid 4x2 HYBRID cab chassis, Trafquip’s new Scorpion® METRO is not only the first MASH TL2-certified TMA to be deployed in Queensland, it is also one of the first Impact Protection Vehicles to be built around a Hybrid-powered vehicle.

The truck’s hybrid driveline, which is powered by Hino’s N04C four-cylinder engine and a 201V AC Synchronous electric motor, delivers a combined 150hp and 470Nm of torque from a very low 1000RPM. It is also the first Japanese-manufactured light-duty truck in Australia to meet Euro 6 exhaust emissions standards.

The unit also includes Hino SmartSafe, a comprehensive safety package found in all 300 Series 4x2 trucks. The SmartSafe package incorporates a range of safety features, including a Pre-Collision System (PCS) with autonomous braking, Pedestrian Detection, Lane Departure Warning System (LDWS), Vehicle Stability Control (VSC) and Reversing Camera with audio.

Supplied by Scorpion’s exclusive Australian distributor A1 Roadlines, the new Scorpion METRO TMA provides MASH TL2 Plus-rated protection from an impacting vehicle weighing up to 2,270kg, travelling at 80km/h and with an impact angle of 25° degrees.

Importantly, as with the larger TL3 unit, the Scorpion METRO TMA has been fully tested and certified to current MASH (Manual for Assessing Safety Hardware) Standards.

In fact, the Scorpion METRO is not only the first TL2 TMA to be fully tested and approved to the latest MASH Standards, it is also currently the only TL2 Truck Mounted Attenuator to be successfully TESTED, PASSED & ELIGIBLE to the current MASH Standards.

The Scorpion METRO TL2 TMA has also been assessed and Recommended for Use throughout Australia by ASBAP (Austroads Safety Barrier Assessment Panel).

The new Scorpion METRO TL2 delivers the ideal combination of compact size, convenient operation, and reduced operating costs. In addition to the obvious fuel cost savings and reduction in carbon footprint, the fact that it’s mounted on the Hino 300 Series Hybrid cab chassis means that it can be driven with a standard car licence, making it much more versatile out in the field.

HP SITEPRINT LAUNCHES IN AUSTRALIA TO BOOST CONSTRUCTION INDUSTRY PRODUCTIVITY

HP’S ROBOTIC SOLUTION ACCELERATES COMPLEX CONSTRUCTION SITE LAYOUTS, DELIVERING UP TO 10X THE PRODUCTIVITY OF TRADITIONAL CHALK-LINE LAYOUT

HP Inc recently announced the availability of HP SitePrint in Australia, following a successful general availability in five regions with a proven track record across North America and Europe.

HP SitePrint is a robotic solution that prints the most complex construction site layouts with pinpoint accuracy, empowering construction pros with up to ten times the productivity of traditional chalk-line layout.

HP SitePrint has been used by General Contractors, Trade Contractors and Geospatial Service Providers on over a hundred projects, across five regions – including North America, UK and Ireland, the DACH region, Benelux, Nordics and Iberia.

“On our first day with the device we did a competition between SitePrint and a manual layout team of four people. The HP solution laid out seven or eight rooms in the time it took the manual team to do two or three!” recalls Gerardo Rivera, COO, L5 Drywall Inc.

“Now we can free up resources to start laying out track much earlier, helping move the project forward faster.”

“The accuracy also impressed us. Make a

couple of errors during the layout phase and you end up ripping out walls later in the project – eating away at your margin. With HP SitePrint you can help eliminate mistakes and move weeks ahead in your schedule,” Rivera added.

A $121.4 billion industry in Australia, the construction sector has a sizeable impact on the local economy and is forecast to have solid growth from FY2026, with total building

expanding to $130.4 billion. Globally, it is a $9.7 trillion-dollar industry, with the construction sector representing almost 10% percent of the world’s GDP, meaning its performance has a sizeable impact on the global economy. However, the industry faces challenges in productivity and human resourcing.

While labour productivity in manufacturing has grown an average 3.6 percent a year over the past two decades, the construction sector has lagged with only a 1 percent increase over the same time period, according to the McKinsey Global Institute. Slow adoption of digital technologies compared to other sectors is seen as a key reason for sluggish productivity in construction.

KEY FEATURES

The HP SitePrint solution has several key hardware and services features, all designed to drive performance and improve workflow, including:

• Autonomous obstacle avoidance - sensors for obstacle detection to increase SitePrint’s autonomy when operating onsite, further allowing layout professionals to focus on other tasks while the robot is at work

• Comprehensive range of inks – a range of eight easily interchangeable inks designed for a variety of surfaces – including, tarmac, rough concrete, plywood, or formwork, amongst others – and different durability requirements from permanent to erasable to improve the versatility of the solution, including three colours (cyan, magenta, black), different compositions that work both on porous and water-proof surfaces, as well as the choice of either permanent or semi-permanent durability. Inks are now delivered via easy to swap in/out cartridges

• Robotic Total Stations to achieve precise layouts – HP SitePrint is compatible with leading Robotic Total StationsRTSs in the industry; including the Leica TS16, Leica iCR80, Leica iCR70, Trimble RTS573, and the Topcon LN-150

• Simple layout management with cloud-based tools:

• The Robotic Total Station set-up process has been integrated into the tablet-operated SitePrint user interface, significantly reducing how long it takes to get a job started

• Cloud functionalities allow users to manage the entire layout workflow from virtually anywhere, log support requests, and share CAD documents from design office to job site

“We’re thrilled to be making our innovative HP SitePrint solution available to customers in Australia and New Zealand,” said Jaume Homs, HP’s Global Head of Sales and Go to Market for SitePrint. “We’ve successfully demonstrated in North America and Europe the ability to radically improve productivity when it comes to the layout process. Now, customers from the ANZ region will also be able to test SitePrint’s efficiency.”

“By digitising what has long been a manual and time-consuming task, SitePrint makes it faster and easier for construction professionals to bring an idea to life on-site, while also providing layout accuracy and reducing costs,” Homs added.

HP SitePrint is now commercially available in Australia. For more information, please visit: https://www.hp.com/au-en/printers/site-print/ layout-robot.html

THE USE OF MASONRY IN AUSTRALIA

by Paul Uno, Director, ETIA

The use of bricks in construction goes back to ancient times. In various regions around the Middle East, evidence has been found of 10,000 year old bricks made from the mud in dried riverbeds. In the ancient Mesopotamian city of UR (which is present day Iraq), there are dwellings built from adobe over 4,000 years ago. In Egypt, clay brick structures still exist that date back nearly 3,800 years.

As a child I remember watching the famous academy award winning Cecil B. DeMille movie called “The Ten Commandments” where it showed slaves mixing straw with mud to produce clay bricks for their people. In the Old Testament, it says people living in bondage in Egypt at the time, used river clay to produce bricks. The clay was usually composed of very fine particles and so would dry slowly. Adding straw would “open up” the clay, allowing it to dry more readily in the sun. It also made the bricks more resist to fracture due to the linear nature of straw which added stability to the clay brick in much the same way that steel bars and macro-synthetic fibres reinforce modern day concrete today (refer to www.barchip.com).

When I visited in Rome a few years ago, I was amazed at structures like the Colosseum and the Roman Forum where Romans had used clay bricks as their building blocks and then glued them together using a Roman mortar (which was a mixture of crushed limestone from the mountains around Rome and ground pozzolanic rock from Pozzuoli near Naples).

Today we have perfected the manufacture of clay bricks, blocks and pavers as well as concrete bricks and blocks.

The two most common clay bricks are pressed bricks and extruded bricks (with the latter constituting about 85% of market use today).

Bricks are placed into kilns which are heated to about 1000 deg C so that the clay raw materials (i.e. alumina and silica) melt and then sinter (i.e. fuse together) to produce the hard, almost glassy brick appearance.

It must be remembered that when clay bricks are sent out onto construction sites, they are extremely dry units and as such will expand over time due to their take up of moisture. This expansion (approximately 0.6mm per m) has to be allowed for or else structural damage will occur (e.g. brick walls crushing at the interface of concrete columns, since the bricks have a lower compressive capacity than the concrete columns they bear against). This issue is sometimes addressed by providing articulation joints in the wall at regular spacings (e.g. 4m to 5m on average, refer to CCAA-TN61).

Good brickies can lay over a 1,000 bricks per day and thus can build a home in quick time without the need of heavy construction equipment such as cranes when compared to other forms of construction (e.g. steel). However, in high-rise construction, one needs to account for the limited ductility in brickwork.

Improved ductility is achieved by using steel reinforcement. Concrete blockwork has reinforcing bars placed centrally within the cores of the units and then the cores are filled with a fluid cementitious grout that cements all the materials together.

Concrete bricks and blocks are manufactured differently to clay. The ingredients that make concrete bricks and blocks (namely cement, sand

and aggregate) need water introduced into the mix to: (i) provide workability to the mix, and (ii) allow for the cement to hydrate which produces spiny growths, which glues the sand and aggregate particles together. To produce a good concrete, it has to be cured (i.e. kept moist for a certain period). Since water is a key part of producing concrete bricks and blocks, the proportion of water that has not reacted with the cement, will slowly evaporate from the units over time to a standard moisture level (lower than when first produced). This results in shrinkage of the concrete units.

Problems can occur when you place a concrete slab over a clay brick wall without providing a slip joint. The concrete shrinks whilst the clay bricks expand and if there is no allowance for slip between these two interfaces then cracking of the weakest link (the clay bricks) will occur.

When handling bricks and blocks on site, it should be noted that a standard clay brick (76 mm high x 110 mm wide x 220 mm long) weighs about 3 kg, whilst a 20.01 concrete masonry block (190 mm high x 190 mm wide x 390 mm long with two cores) weighs about 13 kg. Safety (e.g. wearing hard-hats), especially on high rise construction sites, is therefore a priority should a brick or block accidentally fall from a height during construction.

Fastening to masonry must be done without cracking the unit. Ramset have an ‘Easy-Drive Brick Masonry Anchor’ which is a removable light duty anchor, designed for use in a variety of substrates such as concrete, stone, solid brick/blocks, hollow brick/blocks and hollow slabs. It can be hammered all the way into the hole without pre-expansion. The drive screw’s sawtooth thread makes it easy to drive and unscrew. Further information can be found on their website: www.ramset.com.au

All the necessary requirements of masonry, whether it be clay, concrete or calcium-silicate, is covered in the Australian Standard AS 3700:2018.

At ETIA (Engineering Training Institute Australia), we conduct engineering training courses in over 40 topics very year. This year we are again conducting our Masonry Design and Construction Workshop via Zoom on Tuesday 23rd July 2024.

After migrating to Australia at the age of 14, Mr Lim put himself through university, graduating with a Bachelor of Architecture from the University of Western Australia, becoming a Registered Builder and running a successful construction company before retiring in 2006. His building experience led to his pursuit for an improved construction industry and his property developments, such as the Wyndham LUX Perth Hotel, and Madalyn Manor will showcase his superstructure building technology, the worldwide patented NXT® Building System.

Designed by Mr Lim and NXT’s architectural team, the house will set a benchmark for sustainable, world-class luxury and quality developments. The home has been strategically positioned on the site which will preserve the natural landscape by integrating with the local nature and bushland.

Once complete, the Chittering Manor will be surrounded by botanical gardens and flora that are native to Chittering, and 6,000 new native trees will be planted around a 10 km boundary, for a charitable initiative called Tree for Life.

Located next to the upcoming Chittering Eco-resort and Estates which will feature luxurious guest villas, restaurants and a professional golf course, the construction of Madalyn Manor is expected to employ 170 people, supporting 20 jobs once fully operational in addition to the 350 jobs Chittering Resort will create.

Speaking on his future home, Mr Mataki Lim commented, “I’m delighted to have received development approval on the Madalyn Manor in Chittering.”

“Named after my late daughter Madalyn, the built residence will be a culmination of a shared dream between the two of us, with Madalyn working closely with me on the home’s design.”

“As one of the largest residential homes in the world, the Madalyn Manor will demonstrate the architectural design capabilities and showcase the different applications of the revolutionary NXT® Building System,” Mr Lim said.

“The Chittering estate will be a testament to innovation, sustainability and a dedication to creating something truly remarkable. The estate will not only be one of the largest residential homes in the world, but an investment into the future of residents and the wider region,” Mr Lim added.

The house will be accessed by a tunnel driveway, will have a rooftop alfresco, pool and entertainment area, a rooftop helicopter pad, basement garage, car museum, three lakes in the surrounding landscape and staff accommodation. It will also have a rooftop and indoor cinema, a nightclub, music studio, an arcade featuring laser tag, and a bowling alley.

Together, Madalyn Manor and the Chittering Eco-resort and Estates will generate substantial opportunities to bring tourism infrastructure and services to the region, boosting the local economy and positioning Chittering as an iconic destination in WA. Chittering Resort will be the developer for both projects.

The Development Application for Madalyn Manor was approved by the Council of the Shire of Chittering in February.

RAPID RISE IN AI FOR AUSTRALIA’S CONSTRUCTION INDUSTRY

30% of Australian construction companies are already trialling or using AI to help solve major issues facing the industry, including reducing the costs of construction

Mr Oberoi said, “Priority areas for construction businesses to improve digital adoption include starting small by piloting projects, selecting a digital champion, tracking a range of success measures, building a digital ecosystem, and asking whether your business is AI ready.”

Autodesk, Inc. recently launched the 2024 edition of its joint report with Deloitte, the State of Digital Adoption in the Construction Industry 2024. The report is the second edition of the annual survey and contains insights from 933 construction firms across six markets including Australia, Singapore, Japan, India, Malaysia and Hong Kong.

The report finds 30% of Australian companies surveyed are currently trialling or using Artificial Intelligence (AI) software to increase efficiencies and help to solve major issues facing the industry, including increased labour shortages, higher material costs, and global supply chain disruptions. Additionally, 61% of Australian construction companies surveyed said AI will help them to reduce costs amidst more construction companies entering external administration than any other industry in the financial year to date.

According to Sumit Oberoi, Senior Manager, Construction Strategy & Partnerships, Asia Pacific at Autodesk, “With the challenges facing Australia’s construction industry, AI and technology adoption has become integral for businesses to succeed and to help reduce the costs of construction.

“Disruptive new technologies combined with a challenging business outlook means that construction and engineering leaders in Australia and across Asia Pacific are having to seriously rethink their tools, workforce skill needs and how they interact with clients and contractors.

“Generative AI has exploded onto the agenda for senior leaders with the rapid adoption of tools like ChatCPT, Midjourney and Github Copilot. No industry is immune from the transformative potential of this technology,” said Mr Oberoi.

“Generative AI means that a new project proposal doesn’t need to start from scratch, instead leveraging material and pricing based on projects completed by the company with similar specifications.”

A further 33% of Australian construction companies plan to use AI in future, with AI the most common technology they are looking to integrate into their operations. Australian construction companies surveyed said the benefits of AI will:

• Improve efficiency – 76%

• Reduce costs – 61%

• Increase competitive advantage – 57%

• Increase revenue – 53%

• Improve margins – 53%

• Uncover new ideas and insights – 52%

• Enhance relationship with clients – 49%

• Create new revenue streams – 43%

• Improve employee engagement – 42%

David Rumbens, Partner at Deloitte Access Economics, said, “If all companies with plans to adopt AI do so, AI will have a similar level of prevalence in the construction industry as data analytics or mobile apps.”

Integrating technologies like these into business operations will be no small feat. The construction industry in Australia contributed over $140 billion to the economy and employs over 1.2 million people, according to the latest Australian Bureau of Statistics data.

According to the report, 76% of Australian businesses are reporting a technical skills gap related to digital technology.

“Put simply, construction companies need to get their ducks in a row now so they can implement AI in future years. The first step to successfully implementing AI is data standardisation and having an operational common data environment for teams,” concluded Mr Oberoi.

Additional key findings from the report across APAC include:

• Across APAC, 30% of construction companies are trialling or currently use AI in their operations, with a further 39% planning to use the technology in the future.

• Many businesses believed they received strong business returns or a positive return on investment from implementing AI and other technologies including data analytics, mobile apps, robotics, prefab and modular construction, and construction management software.

• The critical role of technology in supporting business growth is increasingly being recognised. There was an increase in both businesses seeing new technology as assisting with new project work (up from 38% to 45%) and technology in improving internal processes (up from 37% to 43%).

• Foundational technologies are the most commonly used, with data analytics (47%), construction management software (43%) and mobile apps (40%) providing the backbone of construction operations.

• Generative AI is expected to become as pervasive in the construction and engineering industry as these foundational technologies, with 94% of businesses now having plans to integrate AI and machine learning into their businesses.
