A plan for land is a plan for housing - HIA

Following the release of the latest edition of the HIA-CoreLogic Residential Land Report, the HIA has once again highlighted the critical role that land planning and supply plays in housing availability and costs.

“Adelaide, Brisbane and Perth are seeing residential land values grow at a rapid rate, while Sydney and Melbourne’s values remain relatively stable,” stated HIA Senior Economist Matt King.

The recently released HIA-CoreLogic Residential Land Report provides updated information on sales activity in 51 housing markets across Australia, including the six state capital cities.

“The median price of the typical residential lot sold in the March quarter 2024 was $343,480, which is 3.3 per cent higher compared to the same period in the previous year.

“Perth, Brisbane, and Adelaide are currently sitting in the fast lane of growth in residential land prices with double-digit annual increases. Hobart grew by 2.4 per cent over the year, Sydney remained flat while prices in fact fell in Melbourne compared to the previous year,” Mr King said.

“There are evidently two speeds of price growth in residential land market values, with the smaller more affordable capital cities seeing sharper increases in prices,” he added.

“Land prices in the capital cities overall are 4.4 per cent higher compared to the previous year. The regions on the other hand recorded a 0.9 per cent decline over the same period. Land prices in the regions have slowed with the post-pandemic return of households to the capital cities

offsetting the relative affordability advantage of many regional markets.”

“Nationally, the number of lots sold in the March quarter 2024 fell by 9.1 per cent compared to the previous quarter, reflecting the dampening effect of sustained high interest rate environment and the inability of policymakers to bring sufficient land for residential development to market in a timely way,” he said.

“The decline in the number of lots sold in this quarter has been broad-based, as land sales fell across all capital cities and regional markets. Lot sales remain well below the prepandemic average, suggesting an ongoing lack of urgency from state and local governments to bring enough land to market for residential development.”

“Furthermore, it reflects a damaging fixation on taxes and charges levied throughout the new home building supply chain, Mr King continued.

“Excessive taxation and charges on land under residential development is a key reason for the high price of land.”

“Land supply has been inadequate for the best part of a decade, and inefficient and inequitable taxes, such as stamp duty, have only compounded the problem and significantly inflated the cost of land.”

“Before a brick is laid, the median lot prices across many capital city and regional markets are already simply too expensive, pricing vast numbers of owner-occupiers out of the new home building market. It is incumbent upon

governments to adequately supply land for residential development, both Greenfield and infill, to support Australia’s underlying housing demand.”

“An appropriate demand/supply balance should be complimented by the removal of punitive taxes, such as stamp duty, that are pushing new homes out of the reach of many Australian families,” said Mr King.

These comments were echoed by CoreLogic Economist Kaytlin Ezzy, who said, “The recent divergence in capital city land price growth mirrors the recent trends in dwelling value growth, with mid-sized capitals like Perth, Brisbane and Adelaide far outstripping Sydney and Melbourne.”

“Affordability continues to be an important factor driving this divergence, with the high interest rate environment skewing demand away from the more expensive end of the market towards more affordable capital city and regional alternatives,” Ms Ezzy said.

Ms Ezzy also noted that rising land prices, driven by a persistent undersupply, continues to be an important factor hampering the delivery of new housing.

“Since the onset of COVID, median land prices across the capitals have increased by between 16.4 per cent (Perth) and 54.2 per cent (Sydney), which has likely priced many potential homeowners out of the new dwelling market.”

“Additionally, while growth in construction costs has stabilised in recent months, they remain well above the pre-COVID average, further pushing new dwelling ownership out of reach of many households,” concluded Ms Ezzy.

2024 UPCOMING COURSES

A building recovery is on its way, but housing will fall short of target

Despite renewed government efforts to boost housing supply, it is expected to take until the latter half of the decade before tangible benefits emerge, entrenching affordability as a chronic issue, according to leading independent analyst and industry forecaster, Oxford Economics Australia. In addition, the company – which recently releasing findings from its flagship Building in Australia report – warns that the non-residential building sector is also expected to continue its slide into next year before a recovery in commencements kicks in from FY2026.

However, Timothy Hibbert, report author and Head of Property & Building Forecasting for Oxford Economics Australia, says it’s not all doom and gloom for the building sector. While FY2025 will remain soft, national total building construction is set to rise from FY2026 and hit a record level of activity by the end of the decade.

“While we will continue to experience a dwelling stock deficiency, activity will inevitably recover in the residential sector. All build forms will contribute, driving total dwelling commencements to a new record level by the end of the decade,” he said. “And a recovery in non-residential is due from 2026, led by hospital asset renewals and a strong pipeline of data centre builds.”

“All told, from a weakened base, national total building construction is forecast to climb 39 per cent over the four years to FY2029, reaching a record $169.3 billion (constant FY2022 prices).”

The negative pass-through of higher interest rates and strong cost escalation to dwelling construction has almost concluded at the headline level. It is estimated that total dwelling starts will end FY2024 down 10 per cent nationally to a trough of 155,700.

The backlog of work points to home completions holding up over 2024, but strong population growth will continue to power underlying housing demand. Oxford Economics Australia estimates a significant dwelling stock deficiency of 146,000 at June 2024, and expects this will grow further to 164,000 by June 2027.

“A bifurcation has emerged by market,” said Hibbert. “Western Australia is at the front of the pack, with leads for new house demand including land lot sales and lending for new construction well up on a year ago. Queensland is primed as the next to move.”

Improving house construction is set to drive the marginal growth forecast for national total dwelling starts in FY2025 (+2%) to 158,300. While industry capacity is showing signs of improvement in areas, labour shortages remain that will place a speed limit on the early-to-mid stage of the recovery.

Announced policy shifts at both the state and federal level, combined with substantial pent-up housing demand, provide a firm platform for the next upturn. Cash rate cuts are expected from early 2025 – the beginning of a normalisation towards a neutral setting by late 2026.

Attached dwellings are forecast to join the upswing from FY2026 with support from falling interest rates, the upward rebasing of rents, coordinated social housing investment, and planning tweaks in key markets. Build-to-rent development has risen to around one-fifth of apartment starts and is expected to grow this share a little further through late-decade.

Momentum across all build forms is geared to continue over the three years to FY2029, with total commencements rising a cumulative 33 per cent to 241,900 dwellings – a level marginally above the previous record high set in 2016. However, over the five years to FY2029, Oxford Economics Australia forecasts total dwelling completions to total 940,000 – a level 22 per cent below the 1.2 million dwelling National Housing Accord target. Although some states will likely hit their goals, others will fall short by a meaningful margin.

A downturn in national non-residential building is showing through with commencements estimated to have ended FY2024 down four per cent to $51.87 billion (constant FY2022 prices).

“The underlying approval lead continues to soften, which is being compounded by a widening gap to commencement,” said Hibbert. “This suggests a higher dropout rate is playing through – a trend likely to persist near term.”

The slide is expected to continue into FY2025, with starts slipping a further four per cent to $49.80 billion. Private investment has slowed, with activity patchy by sector as higher borrowing costs continue to drag in combination with the upwards rebasing of construction costs. As the impact of cash rate cuts and normalising build costs play through, a recovery is forecast to kick in from FY2026, with activity lifting to $58.15 billion in FY2029.

A surge in warehouse construction, underpinned by strong demand, is set to make it the largest sector by commencement value in FY2024.

“While a normalisation is expected through mid-decade, warehouse activity will remain at an historically elevated level – in part supported by higher construction costs with the emerging multi-storey logistics market in Sydney,” said Hibbert.

“Meanwhile, offices and retail have been hampered by a series of structural headwinds. Given growing pockets of oversupply and higher costs, large office developments are becoming increasingly risky without precommitment.”

This is evident in a thin new project pipeline through mid-decade with starts expected to decline a cumulative 41 per cent over the three years to FY2026. Similarly, the prolonged slide in retail building is forecast to continue near term with higher interest rates and pressure on household budgets set to weigh on investment.

Elsewhere on the private capex front, strong growth in data centres has seen other commercial activity pick up steam. A series of very large campus style developments are slated to break ground in coming years, concentrated heavily in Western Sydney.

“Despite delays and uncertainty surrounding state government finances, the public pipeline remains plump, with recent state budgets delivering few surprises,” said Hibbert. “Health building is set to be the standout.”

All major states are working through a period of hospital asset renewal, undertaking very large $500 million+ developments; at the same time population growth is placing pressure on social infrastructure. Towards the end of the decade, Olympic related works will provide a boost to entertainment building in Queensland.

New research shows confidence boost among business leaders in Australia's volatile construction industry

Kennards Hire's 2024 Construction Confidence Check reveals confidence has increased by 12% from last year, with Australia's construction sector largely viewed as 'stable and resilient to pressures'

Kennards Hire, Australia's largest family-owned equipment hire company, recently released findings from its third annual Construction Confidence Check survey, and the results show an overwhelming majority (93%) of construction business leaders view Australia's construction industry as 'stable' and able to withstand pressures to continue growing, a 12% increase from last year (93% in 2024 vs. 81% in 2023).

The 2024 Kennards Hire Construction Confidence Check surveyed over 410 of Australia's business leaders from small (with 20-99 employees) and large (100+ employees) construction businesses. Its findings provide unique insight into the fluctuating market, how construction business leaders are faring in the current environment, and an outlook on the industry's future.

Survey findings suggest optimism is strong due to cost-saving measures, with 37% of construction business leaders focusing on increasing the quality of workmanship to reduce rework. Similarly, 57% of those surveyed say their business plan includes investing in technology to manage projects more efficiently and effectively over the next 12 months.

Speaking about the findings, Tony Symons, General Manager, Commercial at Kennards Hire said: “Investment into the construction industry is booming like never before, so this year's Construction Confidence Check survey results of increased confidence are not surprising. We are currently seeing unprecedented levels of construction activity in every state in Australia, and this work is expected to continue for at least the next three years.”

“Our annual Construction Confidence Check survey gives us insight into the industry and helps us anticipate trends and stay informed on the challenges facing our customers.”

“For example, we found that on average, construction business leaders surveyed say the proportion of total lost productivity hours on their worksite due to old and faulty equipment is 28%. Opting to hire equipment rather than purchasing gives access to products with the latest technology without the burden of ownership, reduces upfront costs, and enables participation in the sharing economy, which we have also found contributes to our customers' ESG goals,” said Symons.

Industry perceptions on ESG are also included in this year's survey, with nine in ten (90%) construction leaders admitting to having an ESG strategy in place or plans to implement one.

When it comes to prioritisation, construction business leaders surveyed say there are three main factors in their ESG approach:

• Meeting mandatory ESG requirements as a project supplier (34%)

• Collaborating with Indigenous-owned suppliers through social procurement (33%)

• Obtaining project site accreditation from the Green Building Council of Australia (33%).

The findings from the 2024 Kennards Hire Construction Confidence Check are the result of a survey conducted by YouGov from 13 - 21 May 2024. The sample comprised of 410 senior business leaders/ decision makers from small construction businesses with 20-99 employees and large construction businesses with 100+ employees in Australia.

Aycon Constructions fined record $250,000 following VBA investigation

The Victorian Building Authority (VBA) has penalised Aycon Constructions & Building Services Pty Ltd (Aycon) and nominee director Mr Seyit Ayranci a total of $250,000. The record VBA penalty comes after Aycon was immediately suspended in April 2024 for carrying out domestic building work without the required insurance across multiple building sites.

The disciplinary action includes cancellation of Mr Ayranci’s registration and disqualification for three years, the statutory maximum, on the grounds that he was not a fit and proper person and that he engaged in unprofessional conduct.

An intelligence-led proactive VBA investigation found more than 150 building permit applications were supported by a false certificate of Domestic Building Insurance (DBI) and that building work had taken place without the required insurance being in place. The VBA is actively working with its government partners to support affected customers of Aycon.

Speaking about the case, VBA Commissioner and Chief Executive Officer Anna Cronin, said:

“This record penalty shows the VBA won’t hesitate to use its full range of enforcement powers to protect consumers from unprofessional conduct and non-compliant building work.”

“We have zero tolerance for rogue practitioners and are focused on removing them from the industry.”

“Consumers should always ensure their builder is registered and has proof of a valid domestic building insurance policy which is required by law,” Commissioner Cronin said.

By law, DBI must be taken out on any domestic building work over $16,000.

Consumers are reminded of the importance of DBI and not to pay a deposit until their builder has shown proof of a valid DBI policy and certificate of insurance that applies to your property.

VMIA certificates can be verified at: https:// www.buildvic.vic.gov.au/ClaimsPortal/s/ verify-certificate

For other DBI Certificates, consumers are urged to check validity directly with the insurance probider.

Master Plumbers Australia & New Zealand Welcomes Increased Gas Adoption

The Master Plumbers Australia & New Zealand (MPANZ) has expressed its support for more Australians choosing gas over fully electric energy solutions. This shift emphasises gas's reliability and critical importance as an energy source as we transition to a lower-carbon future.

MPANZ spokesperson on Gas, Nathaniel Smith, noted that integrating biogas and hydrogen with natural gas will further enhance the environmental benefits of using gas as technology advances.

“We are seeing a future where the gas in our pipelines is even cleaner, thanks to these innovative blends,” Smith said. “Gas is not just a reliable energy source, but also a pivotal part of our journey towards a more sustainable energy mix.”

Recent industry reports confirm this trend, showing that gas companies in New South Wales, Victoria, and South Australia have increased

their customer bases over the past two years. This comes despite strong campaigns from environmental groups advocating for a transition to electric alternatives and legislative bans on new gas connections in regions like the ACT and Victoria.

The Australian Energy Regulator's latest Gas Disconnection Report reveals significant growth, with Jemena Gas Network in NSW adding 35,000 customers, AGN in South Australia gaining 9,000, and three Victorian companies collectively adding 38,000 new connections. These figures underscore the growing preference for gas among Australian households.

Jemena spokesperson, Michael Pintabona, was recently quoted in the Daily Telegraph and Herald Sun newspapers as attributing this growth to consumer concerns about the reliability of electricity amidst the ongoing energy transition.

“Customers see gas as a crucial part of our energy mix, particularly as we move towards decarbonisation,” he stated.

“While some industry voices, argue that the rise in gas customers is modest compared to solar adoption, the consistent preference for gas highlights its continued relevance,” Nathaniel Smith said. “Property experts also note the appeal of gas for its reliability and efficiency in applications like hot water and cooking.”

“As Australians continue to navigate their energy choices, MPANZ remains committed to promoting the benefits of gas as a reliable and increasingly clean energy source,” he added.

Globally, digital traceability of building products has come into focus. To name just a few initiatives: the UN Economic Commission for Europe (UNECE) recently published the findings of its review of digital product conformity certificate exchange. Meanwhile, UNECE’s upcoming Policy Recommendation No. 49, "Transparency at Scale", aims to establish a scalable framework for supply chain transparency applicable across various ESG criteria.

In Australia, the National Building Products Coalition has published a National Traceability Pledge, signed by major industry organisations including the Australasian Certification Authority for Reinforcing and Structural Steels, or ACRS. The Pledge is a commitment to traceability and digitalisation of building product information across the Australian construction supply chain. It will facilitate the sharing of accessible, verifiable, timely and harmonised information as to a building product’s attributes in association with its physical movement along the construction supply chain.

The Pledge implementation guide notes ACRS as an example of an effective industry scheme, and ACRS Cloud as a good practice project for digital traceability. But what is ACRS Cloud?

TRACEABILITY IN CONSTRUCTION

CALLS FOR BETTER TRACEABILITY

The construction sector is increasingly demanding trustworthiness and transparency, with steel standards specifying traceability of products.

Many industries now use digital product traceability for its many benefits. Textiles customers are demanding better visibility over the supply chain for ethical reasons. In food, we are accustomed to barcodes providing traceability for safety and quality reassurance. In automotives, traceability is used to drive efficiencies across a complex manufacturing process and end-user safety, from tracking components to enabling specific recall in the case of faults.

Supply chains across the globe have taken up digital product certification for better safety and quality; optimised process efficiencies; improved sustainable performance; and increased consumer confidence. It benefits manufacturers, end-users, and everyone in between.

Construction has complex processes, with multiple procurers, manufacturers, and parts sourced from around the world. For safety critical components, compliance must be demonstrated, but for materials like steel, concrete and timber, safety-critical traceability exists mainly in paper-based systems. These systems can be cumbersome and open to fraudulent behaviour – thus reducing confidence in the conformity of the materials and raising questions regarding providence.

In recent years, numerous industry inquests and reports have highlighted quality and traceability of building products as a critical component of ensuring compliance of buildings. Consequently, the industry is seeing a move to holding all parties in the supply chain responsible for the supply of conforming material, to ensure traceability is transparent from end to end. There has also been a substantial push to demonstrate environmental credentials.

Users need public safety; product conformity; sustainability; and productivity during construction – by specifying product certification and digital product traceability from source to site, these needs can be met.

Digital transformation of the construction industry in Australasia is following swiftly: concrete trucks already have QR codes on them, providing digital certification on truck consignments. But what about steel?

Ensuring that the steel product supplied is exactly what was ordered is critical, and increasingly steel products are rejected on delivery when their traceability can’t be verified. The traceability of reinforcing or structural steels is required for compliance with New Zealand standards, because these materials are safety critical. Ensuring they perform as specified by the designer is of utmost importance.

Non-conforming steel can occur in several different ways, including:

Fake or misleading certification:

• Consignments of steel that appear to be certified but, in fact, comprise mixed supply where only a portion of the steel product supplied conforms with the required Standards and the remainder of the consignment is non-compliant (either sourced from different suppliers or from a single supplier with inconsistent quality);

• Steel consignments that have been provided with fraudulent test certificates, either showing certification for other materials, other suppliers, or falsified altogether.

Incomplete or incorrect information:

• Sometimes test certificates do not display all the information required by the Standard; are not in English; show compliance to a different Standard; or are not supplied on delivery.

Most steel products are required to display unique markings which identify the point of manufacture, these include reinforcing steels and mesh. Through these bar markings and the associated documentation from the manufacturer, the product can be traced back to the point of manufacturer and knowledge of any associated transforming works (e.g. cold working such as straightening or bending).

With reinforcing and structural steel products supplied from multiple sources, there are often questions regarding compliance with the material standards, the origins of products and/or traceability through the supply chain.

In steel, while traceability exists in the ACRS scheme, it was previously achieved through analogue systems, processor records and hard copy tags. This made visual verification and cross-referencing time consuming, was still open to fraudulent certification, and was not always consistently applied. Traceability needs to be maintained from manufacturers through processors to the end site.

Until now demonstrating the provenance of material on site has relied on collecting delivery notes to cross check against computer databases to confirm compliance with quality and sustainability standards. So ACRS introduced a better way – the ACRS Cloud app.

INSTANT VERIFICATION OF STEEL

Created by and for the industry, ACRS provides rigorous, trusted, independent, expert, third-party certification of reinforcing and structural steels for:

• Product Certification

• Traceability Certification

• Sustainability Certification

Last year, ACRS introduced ACRS Cloud, the first digital certification system of its kind for steel in the region. It moves ACRS full certification and traceability from source to site to a digital system.

Users through the supply chain can get product piece of mind by checking the nature and authenticity of ACRS steel certificates in the new ACRS Cloud app - available free on Apple and Android.

The app will put assurance in users’ hands wherever and whenever they need it, including: bar and tag markings; where the product has come from; and its validity and its assurance credentials in the form of ACRS’ sector-leading independent certification. Just like online, you will be able to search for certificate holders by mill name or country, and report any concerns, all in the app.

The ACRS Cloud app further protects the market from product compliance issues: not just in poor product identification or deliberate misrepresentation, but by making it easier for users to check steel’s provenance at every stage.

HOW IT WORKS

Under the ACRS Cloud system, batch-specific tags with QR codes are put onto steel at steel producers, fabricators, and processors. In order to make product traceability more secure and accessible, ACRS certificates will carry QR codes which – when scanned at each point – will open validation and vital product information in ACRS Cloud, instantly identifying the provenance of the product and its certification details against a single source of truth.

To make use of ACRS certification, ACRS-certified steel must be specified and ordered – once steel is on site, it’s too late. Then, all builders have to do to confirm that the steel that’s delivered has been certified, is simply:

1. Download the app for free at steelcertification.com/cloud or in your app store

2. Scan the QR code on delivery papers or electronic certificate

3. In the app, select the ACRS ID of the certificate

4. View the certificate in full, including scope, origin, and key dates

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. Available on Apple and Android, the app is completely free to download and use.

ALIGNING WITH INTERNATIONAL STANDARDS

As well as being a signatory and example for the Australian National Traceability Pledge, ACRS also provided views on the UNECE digital product conformity certificate exchange review.

In line with these international efforts, ACRS Cloud provides an excellent example of how national systems can align with global innovations like those proposed in the review.

ACRS Cloud aims to centralise and digitise certification data, improving accessibility and verification processes. This system mirrors the objectives of UNECE by emphasising automated and interoperable data exchanges, enhancing the reliability and transparency of conformity assessments across the supply chain.

By adopting similar principles to those outlined in the review, ACRS Cloud not only advances Australia's digital trade capabilities but also aligns seamlessly with global standards proposed by the UNECE.

TANKER PUMP SERVICE FUNDAMENTALS

At roadworks and constructions sites across the country, water carts work continuously to suppress dust. These unsung heroes rely on efficient, highquality pumps for both fast loading and spraying water.

One Australian company, Australian Pump Industries, understands the vital role these tankers play.

When a pump under-performs or worse still completely fails, it leads to delays and cost implications.

A specialist in engine and hydraulic drive self-priming tanker pumps, the company has developed designs which are both innovative and have real benefits in terms of reducing maintenance costs!

A classic example is their range of cast iron, semi trash tanker pumps that include both high flow and high head options. These feature huge, non-clog style impellers that will easily handle solids of up to 39mm. This means that when filling the tanker from a creek or dam, small stones or debris will pass through the pump without clogging.

The robust pumps feature high sg cast iron impellers and silicon carbide seals for durability. For abrasive water applications the pumps can even be supplied with cast 316 stainless steel impellers.

ESSENTIAL PREVENTATIVE MAINTENANCE

Even big trash pumps can clog. That is why Aussie incorporates a front opening port located below the suction inlet flange. That easily accessible clean-out port enables the operator to promptly clear the inside of the pump bowl in the event of a clog. No need to dismantle the pipework or uninstall the pump.

“We design our self-priming pumps to be robust and simple to maintain,” said Aussie Pumps’ John Hales.

“We recommend regular visual checks to make sure that the pumps are running well. Should an issue occur, these ‘no fuss’ pumps are simple to service too.”

Aussie Pumps recommends weekly visual inspections on the pumps, however if operating continuously, then the checks should be more frequent.

For engine drive pumps, the engine will require regular oil changes and replacement air and fuel filters. Both Honda and Yanmar have extensive national service networks to assist with service and engine parts.

For Yanmar diesel drive pumps, Aussie offers a complete engine service kit, with genuine Yanmar parts, for technicians to carry out the engine service.

Aussie cast iron selfpriming pumps can draft water from dams, creeks and rivers.

SIMPLE PUMP CHECKS

In addition, Aussie Pumps recommends checking for leaks at the back of the pump where the mech seal is located. If the pump has been left to run dry the mechanical seal will overheat and the elastomers will burn out. Water leaking here may eventually seep into the engine causing further damage.

While the pump is running, carry out a traditional vibration check. Put your hand on the pump to feel for any excessive movements and to listen for any unusual noises coming from the unit. Excessive vibration on engine drive pumps can be an indication that the engine mounts need replacing.

Fuel spilt during refuelling can result in premature deterioration of these rubber mounts. Failure to replace expired mounts can lead to serious engine and pump damage.

Routine checks like these can prevent major catastrophic failures before pumps are allowed to “run themselves to death”.

Aussie Pumps has simplified pump maintenance with the introduction of Rejuvenation Kits for their self-priming pumps. The kits include all the elastomers and seals needed to service the pumps, making maintenance straightforward and easy.

They recommend that kits are held on hand to minimise downtime in the event of failure. Simply quote the model number of your pump and your Aussie Pump Distributor can supply the right Rejuvenation Kit for a value packed price.

HOW LIGHT GAUGE STEEL FRAMES ARE TRANSFORMING FACADE DESIGN

The beautiful, curved walls of The Round, a new performing arts facility in the Melbourne suburb of Nunawading, rise gracefully from the surrounding lawns of Nangnak Gardens.

Sweeping red brickwork blends with towering glass facades in the contemporary public building that includes a 626-seat auditorium, rehearsal rooms and a studio theatre.

It has already garnered widespread praise for its striking architecture, energy-efficient design and sympathetic landscaping, but few of those attending its opening night in October 2023 realised that it may have looked very different if framing made from TRUECORE® steel hadn’t been utilised in the building's facade design.

“The main curved wall required a 12x4-metre steel frame specially designed to support the brickwork,” said Luke Cockerell, Managing Director of light gauge steel frame fabricator CMG Frames, who built the much-lauded facade in close collaboration with Melbourne Masonry.

“If we hadn’t used a light gauge steel framing material such as TRUECORE® steel, it would have been practically impossible to pull off without radically changing the plans.”

TRUECORE® steel is manufactured for Australian conditions by BlueScope, a global leader in the manufacture of industry-leading metallic coated steel products. Its strength-to-weight ratio unlocks a range of new possibilities for architects and engineers.

“A frame on that scale can be very heavy,” Cockerell said. “Using highstrength, lightweight TRUECORE® steel helped make the frame light enough to make this design work.”

The intricate facade was designed and verified by structural engineer Felix Dong, principal of LD Consulting Engineers. He agreed that The Round owes its aesthetic appeal to light gauge steel framing made from TRUECORE® steel.

“It’s an advanced lightweight steel, and, in my opinion, is ideal for such a wall,” he said. “The material thickness of the C-sections is onemillimetre, so it has to be incredibly strong. If we hadn’t been able to use it, they’d have had to be much thicker, so we were able to keep costs down while delivering on the design intent.”

TRUECORE® steel won’t burn or support the spread of flame, it won’t warp, twist or shrink, and its lightweight strength lends itself to more detailed and elaborate designs.

Well-engineered facade systems designed in light gauge steel made from TRUECORE® steel can deliver the required lateral and vertical wind resistance and protect the building envelope against heavy rain and extreme heat.

Computer-aided design and engineering software is used to visualise and validate every detail of the facade’s design before it is fabricated, assembled, and transported to site. They can also be craned into position, which may allow for faster installation and fewer crew members working at height.

Cockerell is calling for more engineers to choose light gauge steel frames for facades as it may help improve building quality and lower lifecycle costs.

“It’s gaining in popularity,” he said, “but not everybody knows about all

the benefits. At CMG Frames, we prefer it because of its quality, high tensile strength and the onsite savings it helps unlock.

“What’s particularly impressive about TRUECORE® steel is its industry leading coating technology which improves corrosion. We also like that it’s made in Australia. What’s certainly true is that once you’ve worked with it, you never go back!”

INNOVATIVE CLADDING DEFINES NEW ERA FOR THE UNIVERSITY OF TASMANIA

Set against the backdrop of Launceston’s historic Railway precinct, the River’s Edge project at the University of Tasmania stands as a striking symbol of educational and architectural evolution. As a focal point of a $304 million campus revitalisation, this innovative structure blends functionality with sustainability, setting the stage for the anticipated Building 2.

PROJECT BACKGROUND:

The UTAS River’s Edge project, influenced by the site’s context and history, is designed to reflect the community’s spirit and foster economic prosperity. Integrating contemporary design with the existing campus aesthetic presented unique challenges while supporting approximately 500 jobs and providing training opportunities for 74 apprentices. The project employed a modified Life Cycle Assessment (LCA) to focus on materials’ whole – life embodied carbon. The use of ARAMAX® cladding manufactured from lightweight aluminium was pivotal due to its minimal upfront embodied carbon, durability, long spanning capability, low maintenance, recyclability and local procurement potential.

FIELDERS SOLUTION:

Fielders ARAMAX® structural cladding, renowned for its durability and bold aesthetic, was the ideal choice for this project. The aluminium mill finish reflects Tasmania’s ambient light, giving the building a distinctive sheen that complements its riverside location. Rollforming the ARAMAX® sheets on-site facilitated local contracting and reduced the environmental impact of transport, aligning with sustainable construction practices.

PROJECT EXECUTION:

The implementation of ARAMAX® required innovative solutions to the site’s unique triangular shape and complex geometries, as elaborated by Wardle Architects. Adapting ARAMAX® cladding, typically used for roofing, as a façade element involved meticulous planning. The combination of Fairbrother Construction’s project management and meticulous product installation ensured the cladding met both structural and aesthetic requirements, contributing to the building’s reduced embodied carbon by minimising secondary structural framing

OUTCOMES:

The impact of Fielders’ ARAMAX® on River’s Edge extends beyond aesthetics. It reinforces the university’s status as a benchmark for innovation and sustainability, echoing the Tasmanian Premier, Jeremy Rockliff’s accolade for the project’s “quiet pursuit of the extraordinary”. The building’s craftsmanship, supported by Fielders’ products, not only enhances the campus but also contributes to Launceston’s economic vitality. Notably, the building was constructed with 32.5 percent less embodied carbon than similar projects, setting a nationally recognised benchmark in low – carbon building. This achievement aligns with the University of Tasmania’s commitment to sustainability, showcasing a pivotal steps towards more environmentally responsible construction practices.

LEARNINGS:

The UTAS River’s Edge project highlighted the versatility of ARAMAX® in unconventional applications, particularly as wall cladding rather than traditional roofing. Addressing the site’s complex geometry required innovative solutions, including full-scale prototypes and collaborative workshops with architects, engineers, and fabricators. These efforts were crucial in resolving intricate junction details to maintain structural integrity and meet design requirements.

Moreover, the vertical installation of thin, deep-profile ARAMAX® sheets posed challenges for structural stiffness and water egress. These issues were managed through detailed engineering collaborations. The project also navigated complex fire compliance issues, demanding extensive consultations among fire engineers, building surveyors, and architects to ensure safety alongside aesthetic fidelity.

The successful integration of ARAMAX® cladding on this project has further reinforced its suitability on large-scale architectural projects, driving its adoption in additional University of Tasmania developments and confirming its role in pushing the boundaries of architectural design and building compliance.

CONCLUSION:

At Fielders, the UTAS River’s Edge is a testament to our commitment to delivering architectural solutions that merge sustainability with dynamic design. This project lays the groundwork for the continued transformation of the UTAS campus, with Building 2 anticipated to further this legacy.

AUSTRALIA’S FIRST CERTIFIED PASSIVHAUS TRAINING FACILITY LAUNCHES IN QUEENSLAND

The Construction Training Centre (CTC) recently launched the nation’s first Passivhaus training facility, which will enable industry participants – from carpenters and other industry trades to architects and engineers– to learn about sustainable building principles, among other things.

As the first Certified Passivhaus purpose-built as a training hub, the Bob Marshman Building (BMB) at Salisbury, in southern Brisbane, has adopted a range of innovative sustainable initiatives including circularity, solar panels, EV chargers, and rainwater systems, with the design also promoting pandemic safety and superior indoor air quality. Worker wellbeing, diversity, as well as the use of low-carbon materials were also prioritised, along with waste reduction, local purchasing and upskilling workers in sustainable practices during construction.

A key feature of Passivhaus design principles, the training centre prioritises sustainability by focusing on airtightness, incorporating heat recovery ventilation systems and next level insulation. The design eliminates thermal bridges, ensuring energy conservation.

CTC CEO Phil Diver said the $6 million industryleading centre would showcase innovation in how buildings can adapt to climate change.

“The Passivhaus component was the core element. We wanted to build it around an underpinning foundational philosophy, for us that was the low-energy component of Passivhaus,” Mr Diver said.

“It takes a village to build a Passivhaus, and everybody must be committed. The standard requires the team to problem solve together. We found that the result was directly proportionate to the effort we put into upfront planning before we started building.”

“I’m looking forward to seeing the building’s ability to influence and change design and construction,” Mr Diver added. “I’m hoping in five years' time, that we see Passivhaus become so run-of-the-mill and business as usual, that it is no longer regarded as innovative. It's critical that we get this right and do it sooner; our climate crucially needs us to.”

Australian Passivhaus Association CEO Alexia Lidas said through rigorous Passivhaus protocols, which were becoming prevalent in Europe, the building set a new standard for environmentallyresponsible buildings with the BMB targeting energy savings of between 50 and 90 per cent compared to a traditionally-constructed building.

“Not only are Passivhaus buildings the best choice for mitigating our future climate risk, but they provide the ultimate learning environment,” Ms Lidas said.

“Passivhaus buildings have a positive impact on the cognitive function of occupants. The environment fosters a higher level of concentration, with continuous fresh air, comfortable temperature, and a quiet space to think and listen.”

“It has been well documented that the quality of a learning environment has a direct impact on the leading to higher learning performance outcomes. Students across Queensland will benefit from an adoption of the Passivhaus standard on both new and also to retrofit existing buildings.”

Ms Lidas said the launch of the BMB was well timed, when many Queensland learning facilities were struggling to cope with mould outbreaks –which posed a risk to the health of Queensland’s students.

“We’d welcome the opportunity to work with schools to help them implement the standard,

and Education Queensland could learn from this facility, as Certified Passivhaus buildings create an environment that mould is unable to grow in,” she said.

“With our association, which includes engineers, architects, builders, Government and property developers, growing by 40 per cent in the last year alone, we’ve seen a huge bell curve of growth in the adoption of the standard globally. This is due to the low energy use, climate resilience, health and comfort benefits. Adopting Passivhaus is a no-brainer,” Ms Lidas concluded.

HOW CROSS LAMINATED TIMBER IS SHAPING THE FUTURE OF SUSTAINABLE CONSTRUCTION IN AUSTRALIA

Sustainable construction is becoming increasingly important as industries and nations alike aim to reduce their environmental footprint and embrace eco-friendly practices. Cross Laminated Timber (CLT) has emerged as a pivotal solution in the construction industry, offering a greener alternative to traditional construction materials such as concrete. The adoption of CLT both reflects a commitment to environmental sustainability and demonstrates a broader collaborative effort within the construction industry to pursue and implement solutions that are kinder to the planet, according to Knauf Gypsum.

Thanh Huynh, R&D, Engineering, and Services Director, Knauf Gypsum, said, “CLT adoption in Australia is critical for several reasons, chief among them being the country's vast forest resources and its commitment to combating climate change.”

“Australia's unique environmental conditions and biodiversity, coupled with the increasing severity of climate-related challenges, require a shift towards more sustainable construction materials and methods. CLT is an opportunity to leverage Australia's forestry industry in a sustainable manner, promoting the management of forests in a way that balances ecological preservation with economic benefits,” he said.

“By integrating CLT into construction practices, Australia can reduce its carbon footprint, mitigate greenhouse gas emissions, and contribute to a more sustainable future.”

“The versatility and efficiency of CLT also aligns with Australia's diverse architectural needs and rapid urban development. The material's ability to support faster construction timelines while minimising environmental impact makes it an ideal choice for the country's growing cities and infrastructure projects.”

“The demand for housing and commercial spaces, driven by population growth and urbanisation, calls for innovative solutions that do not compromise environmental integrity,” Thanh Huynh added.

“CLT offers a path forward, empowering Australia to build greener, more resilient communities that are prepared to face the challenges of the 21st century while upholding its commitment to sustainability and environmental stewardship.”

One of the most significant environmental advantages of CLT is its ability to contribute to carbon sequestration. Unlike concrete, which has a high carbon footprint due to its production process, CLT locks in carbon dioxide, which trees absorb during their growth. This process reduces the amount of carbon dioxide in the atmosphere and promotes sustainable forestry practices.

By sourcing timber from responsibly managed forests, CLT use supports an ecological balance, encouraging a cycle of planting, growing, and harvesting that sustains forest resources for future generations. CLT production also uses less energy compared to concrete, lowering greenhouse gas emissions and aligning with Australia's goals to combat climate change and promote sustainability.

Thanh Hyunh said, “CLT’s benefits extend beyond its environmental impact; it offers costeffective solutions that can significantly reduce construction time and associated costs.”

“Prefabricated CLT panels can be quickly assembled onsite, minimising the duration of construction projects and the related expenses. This efficiency is evident in projects like Forte Melbourne and the Adelaide Oval Hotel, where CLT's versatility and efficiency are showcased. These examples illustrate how CLT can meet diverse architectural requirements, from residential buildings to complex commercial structures, proving its capability to adapt to various design needs while maintaining cost and time efficiency,” he said.

While CLT adoption is in its early stages in Australia, other regions worldwide have been using the solution to bolster their construction industries for some time. For example, Scandinavian countries have long been at the forefront of integrating sustainable practices into their way of life, including their approach to building and urban development using CLT. Scandinavia’s successful incorporation of CLT into a wide array of construction projects—from residential to commercial and public buildings— demonstrates the material’s versatility, efficiency, and environmental benefits.

Scandinavia’s climatic conditions showcase how CLT can be used in different settings effectively, providing valuable lessons in achieving sustainability goals. The Scandinavian

commitment to eco-friendly construction, supported by government policies and community values that prioritise environmental stewardship, offers a blueprint for Australia. It highlights how a concerted effort between policymakers, industries, and the public can drive the transition towards more sustainable construction materials and methods.

Thanh Hyunh said, “Scandinavian success stories highlight CLT's transformative impact on construction, offering insights into best practices that can inform and inspire Australian projects. Scandinavia’s experience with CLT underscores the importance of integrating eco-friendly materials into construction to achieve sustainable urban growth.”

In Australia, the construction industry faces macro environmental challenges that have prompted many businesses to adapt and innovate, including Knauf Gypsum. In collaboration with New Zealand’s Xlam, Knauf Gypsum has developed new lightweight wall and floor/ceiling systems specifically tailored for CLT while aligning with evolving building codes, which feature in the recently released Systems+ guide.

“The environmental benefits of CLT, combined with its cost-effectiveness and project efficiency, make it an attractive option for sustainable development, Thanh Huynh added.

“By learning from successful implementations, such as those in Scandinavia and real-world examples within Australia, the construction industry can continue to evolve, adopting practices that not only meet the architectural and functional demands of the present but also ensure the sustainability of the built environment for future generations.”

THE ADVANTAGES OF GROUND SCREWS FOR HOME EXTENSIONS

In the modern development of home extensions, where innovation and efficiency are paramount, there is a growing need among households to enhance their living spaces. This need drives architects, builders, and designers to seek innovative solutions that address the common challenges of time, cost, and environmental impact. Ground screws are a technology that can reform extension projects through building smarter, faster, and greener.

Traditionally, extensions have been built on concrete plinths or foundations, which, despite their widespread use, are not always necessary or efficient. Digging and pouring concrete is time-consuming, dependent on favourable weather conditions, and poses significant environmental concerns, with concrete production a major source of carbon dioxide emissions.

Ground screws emerge as a groundbreaking solution by reducing time and CO2(e) emissions, and can be installed in all kinds of weather.

EFFICIENCY AND REDUCED TIMEFRAMES

A primary advantage of ground screws is their ability to accelerate the construction process significantly. Unlike traditional methods that require extensive excavation and curing times, ground screws can be quickly installed directly into the ground. This shortens project timelines and reduces disruption to households, allowing them to enjoy their new extensions much faster.

Frequent delays and unforeseen expenses are common challenges in construction projects, often leading to budget overruns. Ground screws offer an effective countermeasure by enabling faster installation, which can directly translate to lower labour costs. Additionally, the predictability of this method allows for more accurate budget estimates from the start. By eliminating the need for concrete, ground screws also reduce material costs and waste, making extensions more economical.

SUSTAINABLE CONSTRUCTION FOR THE FUTURE

With an increased emphasis on sustainability in the construction sector, professionals and households are leaning more towards environmentally friendly building methods. Ground screws offer a stark contrast to the intensive carbon emissions characteristic of traditional concrete foundations. They minimise environmental impact by avoiding using concrete and reducing the need for heavy machinery, thereby contributing to lower carbon emissions and a greener approach to building.

A crucial aspect of home extensions is the ability to fulfill homeowners' visions by integrating new structures seamlessly with existing ones. Ground screws provide unmatched flexibility, enabling precise positioning according to architectural designs and accommodating a wide range of models, sizes, and dimensions. This adaptability ensures that whether it's a small conservatory or a large living room expansion, ground screws can facilitate and streamline the building process.

The rapid deployment, cost advantages, minimal environmental footprint, and versatile application of ground screws present a holistic solution to the common obstacles of extension projects. As we move towards a more innovative and sustainable construction paradigm, ground screws represent a pivotal advancement. For those planning their next home extension, the exceptional benefits of ground screws offer a solid foundation for a more efficient and sustainable building future.

$4.2 MILLION SECURED TO DECARBONISE STEEL PRODUCTION

Research project aims to revolutionise the steel industry and bring net-zero one step closer

Australia is the world’s foremost exporter of iron ore, accounting for as much as 53 per cent of global exports annually. The process of decarbonising the iron and steel value chain stands to deliver a substantial contribution to global efforts aimed at reducing emissions.

A team of University of Wollongong (UOW) researchers has secured $4.2 million funding from the Australian Renewable Energy Agency (ARENA) and industry partner BlueScope Steel to investigate ways to utilise low and medium grade iron ore in low emission steelmaking and further decarbonise domestic steel production.

Project leaders, Dr Xue Feng Dong and Dr Raymond Longbottom, together with Professor Brian Monaghan and Dr Paul Zulli, of UOW’s School of Mechanical, Materials, Mechatronic and Biomedical Engineering, will explore the viability of Australia’s abundant, low to medium grade Pilbara iron ores in a potential breakthrough, low-emissions, electric smelting furnace (ESF)based steelmaking route.

The team will work in close collaboration with senior BlueScope ironmaking and engineering officers to help ensure delivery of high impact research and development outcomes across the steelmaking supply chain.

In this project, the team will compare the performance and suitability of three types of Pilbara ore products - lump, fines and pellets - for direct reduction and hot metal production through an electric smelting furnace using a combined high temperature experimental and computational modelling approach.

“This project stands to revolutionise the steel industry and bring net-zero one step closer through assessing the way the country utilises all of its ores and helping establish future low emission steelmaking technology,” Dr Dong said.

“Over the next five years our team will collaborate with our industry partner to thoroughly investigate the long-term viability of utilising Australia’s Pilbara ores in the emerging ESF process, including identifying and addressing some future challenges and process constraints for low emission steel production.”

UOW is the home of the ARC Research Hub for Australian Steel Innovation (Steel Research Hub), which is supporting the transition of Australia’s steel manufacturing industry to a more sustainable, competitive and resilient position based on the creation of new, higher value-added products and more advanced manufacturing processes.

UOW Deputy Vice-Chancellor and Vice-President (Research and Sustainable Futures) Professor David Currow said the University’s team of researchers stood at the forefront of global steel innovation and advancement.

“This funding ensures the momentum of our steel research work, fostering its expansion and continuation,” Professor Currow said.

“The steel industry has long been integral to Wollongong’s identity, and this project will seamlessly integrate its rich history with the city’s forward-looking vision for research and innovation. Through collaboration with our esteemed government and industry partners, the University remains committed to delivering exceptional research, and driving economic and environmental security for the communities in which we operate and for the nation.”

This Project received funding from the Australian Renewable Energy Agency (ARENA) as part of ARENA’s Advancing Renewables Program, with further funding through industry partner BlueScope Steel.

CROSBE UNVEILS GROUNDBREAKING

LOWCARBON CEMENTITIOUS

GROUTS

Australian manufacturer of cementitious grouts, Crosbe, has unveiled a groundbreaking transition to low-carbon grouts, a result of extensive R&D at its western Sydney headquarters. The pioneering products, InfraGrout 110 Low Carbon and InfraGrout 190 Low Carbon, are the first to harness Crosbe's advanced low-carbon technology, promising more products in the future.

Company founder and Managing Director Albert Haddad emphasises that the new products are not just a result of extensive R&D, but also a direct response to customer requests, demonstrating Crosbe’s commitment to understanding and meeting market needs.

“It is well known that the cement industry generates approximately eight per cent of all global CO2 emissions, with four billion tonnes of cement produced each year. For every tonne of cement produced, one tonne of CO2 is released into the atmosphere.”

“To put that in context, if the cement industry was a country, it would be the third-largest emitter of CO2 in the world,” said Haddad.

“For Crosbe, the most impactful way to reduce carbon emissions is to reduce our products' ordinary Portland cement content by using supplementary cementitious materials (SCMs) and alternative cements. Our new low-carbon technology is based on these principles,” he said.

“While the use of SCMs is not a new concept, there is typically a trade-off in the performance of the end products, particularly when replacing most of the cement content with SCMs.”

“We have developed the technology to reduce the cement content in our products by up to 70 per cent and the embodied carbon by up to 48 per cent. By applying our low-carbon technology across all product lines, Crosbe can potentially prevent some 7,000 tonnes of CO2 from being emitted into the atmosphere each year based on our current volumes,” he added.

InfraGrout 110 Low Carbon is a high-strength, ultra-high-flow, zero-bleed, pumpable cementitious grout with extended working time. It is engineered for civil applications, including grouting PT bridge ducts, ground anchors, and soil nails. InfraGrout 110 Low Carbon is approved by Transport for NSW and other Australian road authorities. It is also expected to receive Environmental Product Declaration (EPD) accreditation, which involves a full lifecycle assessment and publication of the data.

InfraGrout 190 Low Carbon is a pumpable, thixotropic cementitious grout specifically designed to encapsulate roof bolts and cable anchors requiring top-down grouting methods. It has been formulated with advanced additives and supplementary cementitious materials to form a low-shrinking, lowchloride, high-yield, and, ultimately, high-compressive-strength grout.

“As an Australian manufacturer that undertakes all R&D in our premises at Seven Hills, we can develop products that suit the specific needs of the Australian market. We’ve started talking to customers about the new low-carbon products and had significant interest in using them on major infrastructure projects,” said Haddad.

The InfraGrout products can be quickly and easily mixed on-site with only the addition of water. They are packaged in rain and tear-resistant recyclable polyethylene bags made from 30 per cent recycled material. The new low-carbon variants of the InfraGrout products will be available alongside the existing ones, but they are expected to be replaced gradually. Over time, low-carbon technology will also be incorporated into other Crosbe products.

When we talk about earthquakes in Australia and New Zealand we immediately know that earthquakes in New Zealand will generally be larger than those in Australia … but why?

In 1915 a researcher named Alfred Wegener proposed a theory of ‘continental drift’ or as we know it today ‘tectonic plate movement’, however very few people believed him at the time. Even early explorers and map makers saw evidence of it (e.g. how the east coast of South America seemed to fit into the west coast of Africa). However, after many years of research and testing, it was proven to be correct and then accepted in the 1960s.

The earth is comprised of many tectonic plates. Landforms are either created or consumed (i.e. subducted) at these plate boundaries. If your country is on a plate boundary, it builds up shearing pressures as it tries to slide past another adjacent plate. This is the case with New Zealand where two plates meet (i.e. where the Australian plate meets the Pacific plate). Once a plate shears at these plate boundaries, an enormous amount of energy is released causing an earthquake (generally leading to earthquakes with magnitudes in the order of 7.0 to 8.0 as maximums).

Australia is not located on a plate boundary, and as such, our earthquakes are less frequent and less violent, with smaller earthquakesgenerally around 5 to 6 magnitude - as a common maximum.

Another cause of earthquakes (especially away from plate boundaries) is the presence of faults in the rock mantle. When the rock fractures at these faults, a large amount of energy is released, as was seen in Christchurch NZ in 2010-2011 and in Newcastle NSW in 1989.

EARTHQUAKE SCALES

The magnitude scale mentioned earlier is usually referred to as the Richter scale. It was devised by Charles Richter and Beno Gutenberg in the 1930s in California. A nomograph was produced which allowed scientists to relate the amplitude of vibrations from the earthquake and the distance from the epicentre of the earthquake to then line up with the magnitude (see Figure 1).

Years later it was realised that this scale did not reflect the true amount of energy released from earthquakes at greater depths and so in the 1970s, a new magnitude scale called the Moment Magnitude scale was introduced. In most cases the difference in values between the two scales is not extreme (e.g. in 1968 in Meckering WA, the Richter scale showed 6.9 but the more correct MMS value was 6.5) however the amount of energy released can be different (the units are in log scale, thus the energy released comparing these two results is different).

STRUCTURAL DESIGN

The way we design and construct buildings in Australia and New Zealand is to comply with the Standards and Codes that govern us, including AS 1170.4 (Earthquake Australian Standard) and NZS 1170.5 for New Zealand, as well as structural Standards such as AS 3600 (Concrete Structures), AS 3700 (Masonry Structures), AS 4100 (Steel Structures) and so on.

In these documents, the basic principles outlined have to be followed to ensure that buildings will not collapse and kill people.

A key parameter in EQ design is “ductility” i.e. the ability of a structure to deform and absorb energy without failing prematurely.

Ductility in steel structures is easily obtained due to the nature of the material itself. In reinforced concrete structures the ductility is provided by the reinforcing steel within the concrete. In both structural steel and reinforced elements, the seismic design of the connections is extremely important.

In timber structures, it too has inherent ductility due to the ability of wood to deform easily.

Masonry on the other hand is not as ductile and thus needs to be reinforced to improve its limited ductility (e.g. reinforcing bars placed into grouted cores within blockwork).

In high rise buildings, structural designers have to be able to determine the natural period of a building (in various modes) to ensure that it can withstand the shear forces that enter the building at its base. Using engineering principles (built into software programs), engineers can determine how much movement will occur, how much amplification of shear forces at the base will move up the building, and how each floor will react based on its centre of mass and centre of rigidity.

The formulas behind the software are very complicated, and involve determination of mathematical functions such as eigenvectors, eigenvalues and modes of participation.

PRODUCTS IN THE MARKETPLACE

Various companies in the marketplace provide specific products aimed at minimising the effects of earthquakes, including:

• Granor (www.granor.com.au) provides elastomeric bearings for buildings, bridges, overpasses, multi-level decks and walkways. In fact, an elastomeric bearing should be considered anywhere where there is a need to provide increased damping or shock absorption to a structure in order to reduce movements and deformation. In particular, tuned mass dampers and viscous fluid mass dampers are the specialty of Granor.

• Ramset (www.ramset.com.au) also provides safety anchors (e.g. SpaTec Xtrem) which are heavy duty, torque-controlled expansion anchors, with an integrated pull-down section, designed for high performance in both static and dynamic load applications, in both cracked and non-cracked concrete and for seismic applications.

• Reid (www.reid.com.au) provides products (e.g. ChemSet™ 801 Xtrem™) which are fast setting Vinyl Esters certified for extreme anchoring applications such as Seismic events.

MULPHA MARKS BUILDING MILESTONE AND ACHIEVES STRONG ICIRT RATING OF 4/5

Mulpha’s ambitious zero-carbon* residential development at Norwest Quarter in the Hills marked a major milestone in the construction of its first apartment tower. This milestone was complemented by Mulpha’s recent achievement of a strong iCIRT rating of 4/5.

The iCIRT star-rating is an independent construction industry ratings tool created by data analytics house Equifax, developed in consultation with the NSW Government, which assesses building professionals and firms against six criteria – capability, conduct, character, capacity, capital, and counterparties.

Mulpha Australia underwent iCIRT’s rigorous and independent review on a group-wide basis and has achieved a 4/5-star rating. iCIRT states a 3-gold star rating or higher indicates a trustworthy business that demonstrates the characteristics to honour its commitments and fix issues as they arise. Mulpha’s iCIRT rating indicates off-the-plan purchasers can buy a Mulpha apartment with confidence that Mulpha has the capability and willingness to deliver reliable, quality buildings that meet expectations.

Mulpha executives and building partners marked the milestone with a topping out ceremony held on the top floor of Lacebark, the first apartment building in Mulpha’s Norwest Quarter. Lacebark is due for completion in the second half of 2025, with more than half the apartments already sold.

Designed by Smart Design Studio and selling off the plan, Lacebark will comprise 81 generously sized one-, two- and three-bedroom premium

apartments and three-bedroom penthouses, all with spacious balconies for entertaining and a choice of lake, golf course, Blue Mountains or landscape views. There are two levels of convenient shops, restaurants and cafes, a resident-only lounge, complete with swimming pool and sundeck, daybeds, a beautiful garden and BBQs.

An enormous open plaza linking Lacebark to Banksia, the second apartment building in the first stage of Norwest Quarter, will feature a wild play forest with misting, timber walkways, forts, slides, decked areas and seating.

Mulpha Head of Developments, Tim Spencer, said: “We are thrilled to celebrate this significant milestone for Lacebark with our top-tier partners, including Parkview Constructions, architects Smart Design Studio, environmental sustainability firm Finding Infinity, landscaping architect Aspect and urban designers Terroir. All our partners are delivering new benchmarks in sustainable design and construction.”

“We are also delighted that Mulpha has received a strong iCIRT rating of 4/5, reflecting our commitment to delivering quality apartment buildings that far exceed minimum code requirements, while setting new benchmarks in lifestyle design, community-focused wellness, sustainability and harmony with the natural environment.”

“This is great for off-the-plan buyers and investors, giving them confidence that what they have bought will be delivered,” Tim Spencer said.

Norwest Quarter development is the first zero-carbon precinct in the Hills and one of the most ambitious in Australia in its sustainability initiatives and design principles. The first stage of Norwest Quarter will deliver 181 net zero apartments powered by 100 per cent renewable electric energy that will consume 50 per cent less electricity from the grid, as confirmed after modelling done by Environmental consultancy Finding Infinity.

Norwest Quarter apartments have achieved a NatHERS rating of 8.1, putting them in the top 10 per cent of NSW and well above the Hills average of 6.6**. Apartment buildings in Norwest Quarter will feature rooftop solar panels and high-performance, centralised air-conditioning, high efficiency lighting and appliances, electric hot water, and induction cooktops.

The Norwest Quarter environment has also been designed to minimise the urban heat island effect through substantial replanting of the natural landscape. Other sustainable community initiatives aim to promote nature and biodiversity of local flora and fauna, including communal gardens, productive beehives for enhanced pollination, worm farms, composting and natural landscapes.

When complete, the Norwest Quarter masterplan will transform over 3.8 hectares of land into a vibrant village for over 2,000 residents who will live amongst 26,000m2 of green open space. Encompassed within the landscape will be nine residential towers containing 864 apartments, and up to 6,000m2 of space provided for cafes, restaurants, neighbourhood shops and childcare facilities***

Norwest Quarter is located within 9 minutes walking distance of the Norwest Metro Station and the emerging Norwest town centre as well as extensive parklands, pathways, and cycleways.

FROM CLAIMS TO REALITY: THE IMPORTANCE OF VERIFIED CARBON FOOTPRINT ANALYSIS

THE IMPORTANCE OF RIGOROUS VERIFICATION

by Dr William Beer, CEO, Tunley Environmental

Accurate and transparent carbon reporting is the backbone of decision making in today’s more environmentally conscious world. To put it simply, you need to be sure that the decisions you are making are based true impacts. The collaboration between Tunley Environmental and Optima Products exemplifies the rigorous commitment required to maintain and verify the accuracy of sustainability claims, ensuring that they translate into real-world impacts. This partnership recently demonstrated its value when an aluminium extrusions supplier approached Optima with an embodied carbon value that seemed too good to be true.

OPTIMA: A BEACON OF SUSTAINABILITY

Optima, with its reputation for high environmental standards, mandates that all aluminium extrusions purchased must have an embodied carbon footprint of less than 2 kg CO2e per kilogram. This if for all raw material, transportation, and manufacturing processes the total emissions for 1 kilogram of aluminium must be less than 2 kg of carbon dioxide equivalents. This is a strict requirement during procurement processes at Optima. Procurement policies related to embodied carbon emissions are all part of Optima's broader strategy to mitigate its carbon impact and drive industry-wide change. Such policies not only reflect Optima’s dedication to combating climate change but also set a benchmark for accountability and environmental responsibility in the sector as a whole.

THE CHALLENGE OF MISINTERPRETED DATA

A potential supplier, eager to secure Optima's business, submitted documentation stating their aluminium extrusions had an embodied carbon of 0.36 kg CO2e per kilogram. On paper, this figure

is exemplary, potentially positioning the supplier as a leader in low carbon aluminium production. Recognising the significance of these claims, Optima turned to their trusted partner, Tunley, to verify the accuracy of the data presented. This examination was pivotal, as inaccuracies in carbon reporting could undermine Optima's environmental objectives and, by extension, its reputation as a leader in sustainability.

UNRAVELLING THE CONFUSION BETWEEN CBAM AND EMBODIED CARBON

Tunley’s investigation unearthed a significant misunderstanding on the part of the supplier concerning the Carbon Border Adjustment Mechanism (CBAM) and the concept of embodied carbon. The supplier had documented their "direct" emissions contribution with regard to aluminium modification at 0.36 kg CO2e/kg. Although this figure is representative of the additional carbon in the aluminium, the supplier identified and presented these to be the total embodied carbon. This, however, fails to account for the "indirect" emissions from upstream suppliers, which are excluded from the 0.36 kg CO2e/kg.

Upon reviewing all documentation and CBAM calculations, Tunley Environmental discovered that the indirect emissions amounted to approximately 11.8 kg CO2e/kg of aluminium. Consequently, the reported embodied carbon are 12.2 kg CO2e/kg, markedly exceeding Optima’s acceptable threshold.

This discrepancy highlights a significant issue in environmental reporting: confusion between different types of carbon metrics is both frequent and widespread in the industry.

CBAM, primarily concerned with levelling the playing field between domestic products and

The role of Tunley was instrumental in uncovering the truth behind the numbers. By analysing the supplier’s data and the associated calculations, Tunley not only prevented a potential breach of Optima’s sustainability policy but also underscored the importance of thorough data verification. Without such diligence, companies risk basing their environmental strategies on inaccurate data, which can lead to serious financial and reputational damage.

LESSONS LEARNED AND THE PATH FORWARD

This incident serves as a critical lesson for all stakeholders in the environmental sphere. The complexity and variability of carbon reporting necessitates expert understanding and rigorous scrutiny. For businesses committed to sustainability, this means investing in partnerships with knowledgeable third parties, like Tunley, who can authenticate and validate environmental claims.

Moreover, this case highlights the need for continuous education and clarity in environmental reporting standards. Suppliers and manufacturers must fully understand the metrics they report on, ensuring that they accurately communicate their products’ true environmental impact. For their part, companies like Optima must maintain rigorous checks on the data they base their sustainability policies on.

CONCLUSION: THE IMPERATIVE OF TRANSPARENCY AND ACCURACY

The collaboration between Tunley Environmental and Optima Products exemplifies the best practices in environmental stewardship. It demonstrates how meticulous attention to detail and a commitment to truth in data is essential in safeguarding a company’s sustainability objectives. As businesses face globally increasing pressure to reduce their carbon footprints, the alliance between Tunley and Optima provides a blueprint for success: robust internal policies supported by expert verification. This isn’t just about compliance or public image - it’s about paving the way for a genuinely sustainable industrial future.
