TasNetworks opts for specialist cable solution

Mon, 11 Mar 2024 00:00:00 +1100

TasNetworks has worked with Swedish specialist cable producer Amokabel to install lightweight covered conductor in the Neika area south of Hobart. The aim is to increase network resilience and reliability in an area previously known for vegetation-related outages.

Amokabel said the installation is the first full-scale installation of the new generation of covered conductor in Tasmania.

The technology consists of conductive wire surrounded by an insulating jacket made of advanced lightweight insulation materials that improves reliability and adds minimal weight. This means that it can be restrung on existing poles to save the distributed network service provider (DNSP) — and therefore the consumer — the cost of replacing or adding infrastructure. The solution was approximately one-tenth of the cost of undergrounding in the same area.

In addition to the cost benefit, lightweight covered conductor is much more resilient than bare wire and easier to install than older covered conductor technologies, such as CCT, Amokabel said. It is highly resistant to dropped tree branches — a common cause of outages — and safer for people and wildlife.

It can also help to reduce the risk of bushfire by 98.8% compared with bare wire, the company said. This is because, unlike bare wire, an overhead line using covered conductor doesn’t produce sparks when it contacts dry foliage or other objects.

TasNetworks aims to compare the new technology with its existing methods while immediately improving network resilience in the Neika area.

“The Amokabel covered conductor system allows us to mitigate many of the potential risks that traditional open wire networks pose at a very reasonable cost, making it a viable standard replacement alternative. These include customer outage or firestart due to vegetation or animals contacting the conductors,” said the TasNetworks team who installed the conductor.

Steve Rutland, Managing Director of Amokabel Australia, said it was a pleasure to watch the TasNetworks team carrying out their first installation of the new-generation covered conductor. “Ably assisted by our local partners Groundline Engineering, who provided supervision and training, the installation went very smoothly, a testament to the preparation done by the project team,” Rutland said.

“The area in question is rugged and heavily treed, a perfect location for our products. Our covered conductor offers a range of benefits in terms of resilience, reliability and safety, making it a clear choice for widespread deployment — especially with the effects of climate change creating a challenging environment for our networks.”

Smart cities, built from scratch

Wed, 06 Mar 2024 00:00:00 +1100

There are few things more ambitious than the smart city built from scratch. These futuristic metropolises are founded on the idealistic principle of high-tech, integrated systems working together for the benefit of the community. In a smart city, the Internet of Things (IoT) works smoothly to produce more efficient transport, more sustainable buildings and even, potentially, better health for citizens through sensors that monitor the contents of the fridge or medication cabinet.

With their reliance on interconnected systems, the IoT and sustainable technologies, smart cities present a host of opportunities for the electrical, communications and data industries.

The smart city concept is both old — with origins in the late 1960s — and remarkably current, as witnessed in the imminent plans for Indonesia’s new capital Nusantara and Australia’s very own Bradfield, an aerotropolis destined for Western Sydney. These days, most cities deploy some form of smart technology, with many identifying as ‘smart cities’ on the basis of this, but the smart city built from the ground up represents a whole new level of vision and risk.

Given that a few smart cities have been built over the past 20 years or so, while various others have failed before getting off the ground, and yet more are planned for the near future, now seems like an opportune time to assess the effectiveness of the smart city idea in order to avoid mistakes in future.

Getting it right

Two recent studies have examined the opportunities and challenges presented by smart cities through analysis of carefully chosen datasets.

‘Smart Cities—A Structured Literature Review’¹, published in July 2023, used Web of Science and Google Scholar to identify relevant research articles on smart cities. It then combed this body of research using a list of 10 questions. These questions related to the definition of a smart city, its advantages and disadvantages, implementation challenges and funding, among other topics. The study also analysed the implementation of smart city solutions in international contexts and proposed strategies to overcome associated challenges.

‘What is the impact of smart city development? Empirical evidence from a Smart City Impact Index’², published in November 2023, developed a special index to measure the positive and negative impacts of smart city development. Its focus was on cities in South Korea, a country that began to initiate smart city projects in the mid-2000s. This study compared non-smart cities with first-wave smart cities (which focus on transportation and security infrastructure) and second-wave smart cities (which emphasise comprehensive urban management).

Cautionary tales

Both studies identified security and privacy as areas of concern in the modern smart city.

“The integration of technology and data-driven solutions in smart cities has the potential to revolutionize urban living by providing citizens with personalized and accessible services. However, the implementation also presents challenges, including data privacy concerns, unequal access to technology, and the need for collaboration across private, public, and government sectors,” wrote the authors of Smart Cities—A Structured Literature Review.¹

Indeed, this was the main reason Canada’s ambitious Sidewalk Toronto project folded in 2020. Proposed by Google subsidiary Sidewalk Labs in response to a callout by Waterfront Toronto in 2017, the ultra-sustainable neighbourhood was going to be built on 12 acres of industrial land along Toronto’s waterfront. Critics, however, objected to the minute level of digital scrutiny that residents would seemingly be subjected to, allegedly for their own benefit — something that was made even less appealing given Sidewalk Labs’ close relationship to one of the world’s data giants.

Some commentators and researchers³ have similar concerns about Toyota Woven City, a high-tech, ultra-sustainable community that the mobility company started building in 2021 in Tohoku, at the base of Mount Fuji in Japan. Run on hydrogen and billed in Toyota’s promotional materials as a “human-centred, living laboratory”, the community is designed to eventually be home to 2000 people. In Woven City, sensors will monitor residents’ health, track their food use and prompt household robots to keep the fridge stocked. Most of this highly surveilled population will be Toyota employees and their families.

In contrast to Sidewalk Toronto, the Songdo International Business District in Incheon, South Korea, has achieved a degree of success. Built on 1500 acres of land reclaimed from the Yellow Sea and completed in about 2015, the district is by all accounts a marvel of integrated technology, with sensors monitoring energy use and traffic, loads of smart home features and — impressively — pneumatic tubes that pump residents’ garbage directly from home to the rubbish facility.

However, it seems that all the seamless technological integration in the world cannot produce a vibrant community. The district has not as yet attracted the multinational tech companies and skilled international workers that were part of its initial vision, and residents report feelings of alienation and coldness⁴, with a lack of opportunities to meet others in the flesh.

Bradfield: “Australia’s first 22nd century city”

Named for the chief engineer of the Sydney Harbour Bridge, Bradfield is part of the NSW Government’s Greater Sydney Region Plan for a “metropolis of three cities”: the Western Parkland City (Bradfield), the Central River City (Parramatta) and the Eastern Harbour City.

Part of what is ultimately planned to be a much larger aerotropolis, Bradfield City Centre will be constructed on 114 hectares in close proximity to the new Western Sydney International Airport at Badgerys Creek. More than 15,000 people are expected to eventually live there in about 10,000 new dwellings, with 20,000 new jobs created. Promotional videos from the Western Parkland City Authority show an artist’s impression of a vibrant, walkable city with plenty of landscaped public space where young professionals and families gather. The city’s draft Master Plan is currently on public exhibition.

ECD contacted the Western Parkland City Authority (WPCA) for details on how Bradfield City Centre is progressing.

A WPCA spokesperson said that the city’s First Building, housing commercial industry tenants and the Advanced Manufacturing Research Facility (AMRF), is due to open in mid-2024, adding that construction would soon get underway on the Second Building, the two-hectare Central Park, and the roads and services within the city.

Integration is a primary consideration

The WPCA spokesperson said that the first stage of Bradfield City Centre will integrate technology in order to improve day-to-day experiences in the city and allow people to stay connected.

The WPCA is planning a system of innovative multi-function poles capable of accommodating lights, sensors, cameras and telecommunications equipment to ensure Bradfield has the supporting infrastructure in place for smart city technologies, the spokesperson said.

A fibre-optic network throughout the new city will support rapid connection to this digital infrastructure.

At the time of publication, the WPCA was on the point of releasing an expression of interest (EOI) for the market to engage in a number of opportunities to provide digital infrastructure and services supporting smart city functionality in Bradfield City Centre and to improve the visual amenity of places.

Sustainability measures

A key concern in relation to Bradfield has been its location in one of the hottest parts of Sydney, where temperatures during heatwaves can be up to 10 degrees higher than in the coastal suburbs.

The WPCA spokesperson said the draft Master Plan includes controls aimed at curbing the urban heat island effect, including a minimum tree canopy coverage target of 40% and the use of water-sensitive urban design to keep water in the environment to green and cool the city.

“Buildings will feature greenery in the form of extensive landscaping and green roofs, to cool and protect buildings,” the spokesperson said. “Planning controls also aim to reduce active heat production from electrical systems and transport in the city.”

Additionally, resilience and climate change risk principles are being incorporated into the design of buildings and infrastructure.

The design of the First Commercial Building exemplifies these principles, with the spokesperson saying it “sets the benchmark for Bradfield City Centre as a connected, green and advanced city, while promoting design that is of its place and connected to Country”.

The First Building has a timber structure composed of prefabricated modular components that are fixed together. This means that it can be disassembled, expanded and even relocated over time.

Water management is an important consideration, with the building capturing and storing rainwater for landscape irrigation. As might be expected, the First Building roof will also incorporate solar PV to generate power.

Additionally, the roof will be filled with native planting and low-maintenance vegetation to support local biodiversity and improve the microclimate of the building, the WPCA spokesperson said.

Gathering momentum

Once Bradfield’s Master Plan is finalised, land will be released for private sector development, building on the momentum created in the lead-up to Western Sydney International Airport opening in 2026 along with the new Western Sydney metro line.

The Western Parkland City Authority intends to create “a thriving 24/7 hub of culture, creativity, and innovation over time”. It will be fascinating to see it taking shape.

Boosting women in solar

Wed, 06 Mar 2024 00:00:00 +1100

Brighte, an Australian financial institution specialising in renewable energy plans, has announced the two recipients of its Women in Energy Scholarships in Tasmania. Brighte is the exclusive administrator of the $50m Energy Saver Loan Scheme (ESLS).

This year the scholarships have been awarded to Chey Sullivan, a NECA Education & Careers apprentice who is hosted to Contact Group, and Erin Kingston, from Derwent Electrical.

The Brighte Women in Energy Scholarships are an extension of Brighte’s partnership with the Tasmanian Government and are aimed at supporting the growing local green energy sector while also boosting women in the industry.

“To meet our ambitious net zero targets, we’re going to need thousands of electricians skilled up to help power the green revolution — and many of those must be women,” said Brighte Founder and CEO Katherine McConnell.

Valued at $3350, each scholarship includes assistance with the costs of the training course and funding for the first year of the Clean Energy Council’s accredited solar installer fees. Recipients must be apprentices with a proven commitment to studying and to furthering their knowledge of renewable energy.

“Studying a course in renewable energy was always something that I wanted to pursue,” Sullivan said.

“With government mandates and procedures moving toward a cleaner, greener state, I think new energy jobs represent an opportunity to be at the forefront of some of technology’s most exciting advancements.”

TasTAFE CEO Grant Dreher said TasTAFE was proud to support the Brighte Women in Energy Scholarships and their promotion of renewables.

“We are starting to see more women taking up apprenticeships in traditional trades, but there is still work to do. We are working with industry and businesses such as Brighte to proactively encourage more women into trades,” he said.

During her announcement of the successful award recipients, McConnell made reference to the recent Senate Inquiry into Residential Electrification where Electrical Trades Union workers’ rights director Katie Hepworth noted that Australia would need 32,000 additional electricians by 2030 to meet its renewable energy target — and further, that only 2% of electricians today are women.

“With our extensive network of vendors both in Tasmania and nationally, we want to use our influence to encourage more women to join the industry and to be part of this transformative growth story,” McConnell said.

"New era" for Aust solar installers and designers

Wed, 06 Mar 2024 00:00:00 +1100

The Clean Energy Regulator (CER) has recently appointed Solar Accreditation Australia (SAA) as the new solar installer and designer accreditation scheme operator under the Small-scale Renewable Energy Scheme (SRES).

The SRES is an Australian Government program based on tradable certificates called small-scale technology certificates (STCs). Eligible installations of rooftop solar PV are entitled to STCs, creating a subsidy for households and businesses that install these renewable energy technologies.

“This is a significant milestone in our shared commitment to enhancing standards, transparency and accountability across the solar energy sector,” said Stephen Robertson, Chair of SAA.

“Today marks the beginning of a new era for Australia’s dedicated and highly skilled solar installers and designers, with the launch of an independent, not-for-profit and single-purpose entity to support compliance and raise standards across the industry. SAA is committed to ensuring integrity, accountability and responsible practices within our industry,” he said.

The SAA stated that it will work collaboratively with industry, government bodies and other relevant stakeholders to ensure the accreditation scheme promotes best practice, encourages continuous professional development and supports a growing workforce to deliver smart energy solutions for Australian households and businesses.

The CER’s announcement was welcomed by industry organisations including the Smart Energy Council (SEC) and Master Electricians Australia (MEA).

“The industry wanted to see a collaborative whole-of-industry approach to accreditation delivered by a separate and independent body,” said John Grimes, Chief Executive of the Smart Energy Council. “That is what SAA is delivering … to support the federal government’s ongoing commitment to program integrity.”

Master Electricians Australia President Peter Matthews said the MEA was pleased to support the creation of a new independent solar designer and installer accreditation service provider.

With the SAA’s accreditation scheme now in effect, the Clean Energy Council’s (CEC) accreditation services have ceased. Accredited persons must transfer their CEC accreditation to SAA by 29 May 2024 to maintain their accreditation and STC eligibility.

Belated electric shock report leads to $12K fine

Tue, 05 Mar 2024 00:00:00 +1100

An electrical contractor in Mandurah, WA, has been fined $12,000 after taking six weeks to inform authorities about an apprentice’s electric shock.

Ballantyne Commercial Property Services had been contracted to carry out electrical work at a premises in Beckenham on 21 February 2022. One of the three employees who attended the site was a third-year electrical apprentice, who received an electric shock after touching live wires while disconnecting cables in the ceiling space.

The electric shock was reported to Building and Energy on 1 April 2022 by a Ballantyne employee who contacted the safety regulator because the company’s managers had not reported the incident as required by law. A Ballantyne director later informed the network operator, Western Power, on 11 April 2022.

At Armadale Magistrates Court on 9 February 2024, the company pleaded guilty to not immediately reporting an electrical accident to the network operator as required by WA’s electrical licensing regulations.

While noting the apprentice was not seriously injured, Magistrate Clare Cullen said that this was a matter of good luck rather than good management. She added that the company directors would be aware of their reporting obligations and it was a “brave act” by the employee who first reported the incident.

Cullen acknowledged Ballantyne’s guilty plea, remorse and prior good character, as well as the low risk to the public, but added that the six-week reporting delay had an impact on inquiries and safety actions related to the incident.

WA’s Director of Energy Safety, Saj Abdoolakhan, said that electrical incidents must be reported immediately to ensure the area is made safe and an investigation can commence as soon as possible to address any underlying issues.

“It is incredibly fortunate that the apprentice was not seriously injured and no one else received an electric shock while this incident was unreported. Above all else, safety must be the primary consideration for everyone involved in the electrical industry,” he said.

Light and sound signalling systems

Fri, 01 Mar 2024 00:00:00 +1100

The primary purpose of signalling devices is to convey unambiguous messages. However, in industrial (and other) settings there are numerous situations that require more complex solutions. So, which factors should be considered as the most important ones?

The answer to this question is simple: safety is always the key factor. Regardless of the context, the role of a signalling system is to inform operators and bystanders of specific hazards or conditions that require exercising particular caution.

Virtually every workplace, even an office, is fitted with a light and sound signalling system. We are often not aware of its presence, but it is, for example, an indispensable part of a fire alarm system. A fire alarm system uses lights and sirens, just like many other warning systems in factories, machinery parks and urban infrastructure elements. The same applies to anti-intrusion alarm systems. Therefore, see below for an overview of solutions and applications related to the broadly defined term “signalling”.

Legal regulations and good practices

Firstly, note that most regulations related to signalling systems in industrial applications and workplaces are enforced regionally, mostly within the framework of OHS regulations, fire safety standards etc. Therefore, guidelines provided by competent authorities must always be respected when installing such a system. For this reason, signalling devices supplied by global manufacturers can often be modified by the purchaser and adapted to local requirements (e.g. by changing the light colour, adjusting the volume and tone etc.).

Now, let us list a few aspects that must also be taken into account when it comes to designing and installing signalling systems:

Alerts must be well visible and audible, and, if possible, unambiguous.
Each situation threatening human health or life must be signalled with an alert, similarly as in the case of indications displayed in hazardous zones.
The signal intensity must take into account the environmental conditions and workplace characteristics. In areas where heavy machinery emits noise and workers are required to wear hearing protectors, the volume of alerts must be suitably adjusted. Similarly, visual signals alerting technicians who work in welding masks must also be adequately intensive.
Transmitting a message is often related to a breakdown or emergency, so the power supply and control systems of signalling devices should be conditioned by but independent from the operation of the system/machine with which they work, and that applies especially to conveyors or production lines in factories and warehouses.
Signalling systems should undergo regular inspections and maintenance.
Regulations change frequently, buildings get renovated, and machinery is modernised, so it is worth considering signalling system scalability already at the design stage.

Each company should strive to develop uniform, clear rules and procedures for its labelling and signalling systems. Ideally, these should be intuitive or at least universal (like road signs and traffic lights). In practice, it is not always feasible. However, simplicity should always be one of the key assumptions. Its additional advantage is that it will also facilitate new personnel onboarding.

Types of signalling devices and special cases

Signalling devices are generally divided into optical (light) and acoustic (sound) units; however, this division includes different subcategories defined by individual design solutions.

Technical aspects

First of all, it must be noted that there are several technical parameters to be taken into account, regardless of the signalling device type. These include electric parameters: power supply source (and voltage) and control method. Signalling devices can be activated as soon as power is applied, or require a separate signal to be provided. In other cases, (e.g. certain beacon towers), the device operation is controlled via pulses or digital protocols.

The degree of protection used is another important factor to be considered. Most products come with the IP65 or IP66 degree of protection, i.e. full dust-tightness and resistance to water splashes or even pressurised water jets (in practice, this means that a module can be washed with a high-pressure washer). Thermal tolerance is also important, in particular when products operate in extreme working conditions (e.g. in the metal processing industry or in cold stores).

Sound signalling devices

Sound signalling devices convey messages by emitting a sound with a specified tone and volume. These two parameters are directly related to components used in the device, e.g. a piezoelectric buzzer or speaker or even a ringer. As many products available on the market are based on electronic components, you may pre-set the signal intensity and type, which facilitates the unification of warning and alarm signals within the entire company.

Sound signalling device based on a membrane siren by AUER SIGNAL.

Ringers are used in fire alarm systems — product by KLAXON SIGNALS.

A typical sound level for most sound signalling devices is equal to or higher than 100 dB, which guarantees alert audibility, even in noisy production facilities. In extreme cases, signal intensity up to 120 dB is acceptable, but it must be borne in mind that a device emitting sound at this level must be placed in the optimum position (e.g. at a safe height), as emission of such a strong signal close to someone’s ear may result in hearing loss.

Voice messages

A voice signalling device is a relatively frequently used type of sound signalling devices, so it must definitely be mentioned in this article. This term is not entirely accurate, as, in practice, they are not necessarily designed to reproduce the human voice, although that is their most common purpose. They can be used to communicate more complex content, e.g. direct building occupants to proper escape exits during an evacuation process. A message is prepared in the form of a digital recording (MP3 file), placed in an emitter (usually on a memory card) and played back through speakers when triggered. To this end, some products are supplied with ready-made, professionally produced recordings.

Light & light and sound signalling devices

“Conventional” strobe signalling device with a xenon light source manufactured by WERMA.

Light signals are strictly codified by regulations specifying the intensity, colour and frequency of various messages, which applies in particular to alarms and warning lights (e.g. used in heavy machinery transported by roads). Rotating beacons are employed in industrial plants to alert users about, for example, machinery start-up, gate closing/opening, mechanism jamming, etc. They provide perfectly legible indications commonly used in transport, logistics, warehouses, etc. In the past, they were equipped with halogen or xenon lamps, but they are now being gradually replaced by more durable and almost equally bright semiconductors, i.e. LEDs.

Light and sound signalling devices are required or at least recommended for numerous reasons. Their “twofold” messages are more likely to be noticed by the audience, especially in suboptimal conditions, e.g. on a sunny day, a flash emitted by a lamp will be as muted as an alarm emitted by a buzzer against a background of heavy machinery noise. Therefore, lamps integrated with sound emitters are very popular types of signalling devices. Their components are the same as those described above, and they are available in various combinations, i.e. an intense sound signal does not necessarily have to be accompanied by a light signal of equally high intensity (e.g. in fire alarms, strong flashes might disorient the evacuees).

Signalling columns (beacon towers)

Typical beacon tower manufactured by QLIGHT.

Beacon towers, i.e. a combination of several lamps and an optional speaker in the form of a small tower are a non-standard type of light or light and sound signalling devices. Such solutions are most often supplied as modular units, but compact versions are also available (with a conventional set of colour codes, i.e. green-yellow-red). Obviously, modular versions facilitate adjusting a signalling device to specific working environments, certain conventions or local regulations. It involves not only the light colours, but also the sound signal types (continuous, intermittent, pulse). Scalability is an important advantage of modular beacon towers, too.

Therefore, in some cases, where it is originally sufficient to install a single lamp, a modular solution is also worth considering. Beacon towers are usually installed with a base that also acts as a connector or distributor, and sometimes even on an additional foot with a sleeve to ensure its optimum height and visibility. They come in round (cylindrical) and wall-mounted versions (with a curved face for the widest possible emission radius).

Explosion hazard zones

Signalling device conforming to the ATEX directive manufactured by CLIFFORD & SNELL.

Explosion hazard zones (Ex) are probably the most unique operating environments for signalling devices, where volatile or liquid flammable substance leakage may occur (gasworks, petrochemical plants), or where hazardous materials are stored (e.g. munitions). In such spaces, both effective signalling and the necessity to use properly attested and certified products are equally important. It is quite obvious: if, on activation or during operation, a signalling device generates a spark, it may cause ignition. Therefore, solutions such as ringers or electromechanical components are out of the question. Moreover, signalling devices must be supplied via intrinsically-safe separators or Zener barriers fulfilling the same function. It is required by international regulations, such as the ATEX Directive implemented in the EU.

The big value of infrastructure digital twins is finally here

Thu, 29 Feb 2024 00:00:00 +1100

Unless you have been living under a rock for the last few years, you have probably noticed that digital twins have become a hot topic across infrastructure sectors. What was once considered futuristic eye candy is now a powerful and valuable way to combine and leverage data from disparate sources and multiple disciplines. Sure, digital twins are particularly useful for visualisation, but their real power comes from combining timely, yet potentially siloed data for a holistic, virtual view of an infrastructure asset.

Whether in design, construction or asset operations, engineering firms and owner-operators are facing resource constraints. Project demand is outpacing the number of people available to do the work, driving the sectors to transform and change how work gets done. Adopting digital twin-powered workflows can boost productivity, increase throughput and deliver better results. Infrastructure digital twins are becoming critical enablers of the design, construction and operation of assets.

Digital twin-powered workflows enable firms to seamlessly conduct design reviews and structural analysis, calculate carbon footprints and quantity take-offs, and plan construction schedules, all based on a single, up-to-date, data-rich digital twin. An infrastructure digital twin is a structured way to federate information from various systems. In addition to bringing siloed data together, a digital twin can unlock data from existing design files, essentially ‘lighting up dark data’. This unlocked data is the foundation for quickly and easily applying artificial intelligence and machine learning to drive actionable insights and better outcomes.

If you are still not convinced, here are some specific examples of how digital twins are being used in each phase of infrastructure lifecycle management.

Planning phase

After identifying the need for a new asset or infrastructure system, the planning phase begins by collecting information on costs, timing and implementation. Planning also includes feasibility studies, due diligence, asset specifications, budget estimates, contract negotiations, funding and public comments.

Infrastructure digital twins deliver value in the planning phase by helping to evaluate whether a project is economically or technically viable. A digital twin also presents a virtualised as-built environment or renders conceptual designs for stakeholder engagement.

A real-world example of an infrastructure digital twin being used in the planning phase is London’s South Dock Bridge, a high-profile pedestrian bridge linking South Quay with the city’s iconic Canary Wharf business district. Led by Arcadis, a company specialising in sustainable design and engineering, the project’s digital twin incorporated the complexity of existing multistorey basements with above-ground rendering so that all stakeholders — including the public — could visualise the design and create a plan to mitigate construction challenges in the highly developed neighbourhood.

Design phase

The conceptual project idea comes to fruition with technical details and specifications for its construction and operation, which includes requirements and criteria that consider regional, urban and environmental data, as well as other important information.

Digital twins can be used for design optimisation, clash detection, energy savings and carbon footprint reduction. They also provide better visibility into building information modelling (BIM) data and can run simulations to reduce the risk for issues such as flooding and subsidence. Another big benefit of using a digital twin in the design phase is that it can be used as a single source of truth for multidiscipline engineering data, keeping engineers, project managers, owner-operators and other stakeholders on the same page with the latest information.

WSP, an environmental engineering firm, used digital twins to design its Port of Melbourne Rail Transformation Project. With only three months to deliver final designs, WSP presented weekly design reviews to a large and involved stakeholder community, including the construction contractor and port officials. This real-time collaboration led to a right-first-time design approach, which identified potential issues early on, reducing waste and rework.

Construction phase

During construction, infrastructure digital twins can bridge the gap between project management and the field by making all plans and data accessible through any mobile device. Digital twins can expand BIM from 3D to 4D to enable better scheduling. Better scheduling and resource planning can increase the safety and efficiency of construction sites, helping to reduce carbon emissions, soil movement and delays. Digital twins can also expand 4D to 5D and include cost information, making budgets and change orders more predictable during construction.

For design and consulting firm WSB, leveraging infrastructure digital twins and workflows on road transportation projects has shrunk schedules, generated savings and, most importantly, reduced traffic disruption. For example, digital twins saved the Minnesota Department of Transportation more than US$15 million during the conversion of 2.8 miles of TH 169 into an expanded freeway with upgraded interchanges, bridge and underground utilities.

Operations and maintenance phase

The operations and maintenance phase ensures an asset performs effectively throughout its life. The phase includes monitoring, maintenance and upkeep, scheduled repairs, part replacement and inspections.

Real-time data from IoT sensors in the field can be incorporated into infrastructure digital twins to help with remote monitoring and inspections, saving time and money — and, in the case of hazardous inspections, increasing safety and reducing risk. Digital twins can optimise maintenance schedules, reduce the risk of failure and allow project managers to make better decisions related to asset replacement or decommissioning.

The Yuba Water Agency uses a digital twin to actively monitor the New Bullards Bar Dam, the second-tallest dam in California and the fifth-tallest dam in the United States. Given the height of the dam, the remote location and the rough terrain surrounding the dam, physical inspections were dangerous and difficult. A digital twin integrated with numerous IoT sensors, however, allows the Yuba Water Agency to implement remote monitoring and inspection, saving time and money and reducing risk to personnel. In addition, the digital twin proved invaluable in ensuring the dam’s structural safety following a recent earthquake.

Similarly, the Australian Rail Track Corporation is implementing a digital twin across its entire network of 9000 km of track. Using the digital twin to facilitate predictive maintenance and proactively identify potential failures will help the company avert delays, avoid downtime and minimise risk.

Conclusion

Regardless of infrastructure type, over time the digital twin of a project or an asset will become both its lifeblood and its central nervous system. Whether you use it during planning, design or construction, or for continuing operations and maintenance, an infrastructure digital twin can save time, money and rework; reduce delays, waste and risk; and increase safety. Overall, using an infrastructure digital twin results in better project delivery and asset performance.

Saul Griffith to kick off community energy event

Tue, 27 Feb 2024 00:00:00 +1100

The Coalition for Community Energy (C4CE) will be holding a Community Energy Congress from 6–7 March at the International Convention Centre in Sydney. The event will bring together leaders from communities, government, infrastructure companies and business to discuss community participation in the energy system.

With community energy projects, communities are directly involved in developing, producing, distributing, selling and buying energy assets and their output. Projects can take various ownership forms, including full community control or collaborating with public and private enterprises.

Community energy can encompass household electrification and efficiency programs, small-scale cooperatively owned solar PV installations, a community energy retailer, bioenergy or hydro systems, or a large-scale, community-owned wind farm. They are volunteer-run and help support the local community.

Last year, 55 community energy groups raised $74.5m for energy infrastructure, with another $6m in value from in-kind support and volunteer hours.

“We’d like to see consistent support from governments to grow this workhorse of the energy transition. Homes, businesses and whole communities won’t transition to renewable energy without trusted, independent and custom advice and help,” said C4CE Chair Heather Smith.

Topics that will be discussed at the congress include community batteries and microgrids, finance, partnerships and energy resilience. Rewiring Australia founder Saul Griffith will deliver the keynote speech.

The theme for this year’s congress is “Fast, Fair, and Vital”, highlighting the speed of transition, the values and outcomes that communities want in the energy transition, and the vital nature of energy to everyday lives and businesses.

Tickets for the Community Energy Congress are available now via Humanitix. The congress is being held on the sidelines of the Smart Energy Expo, so attendees also need to register for the expo to enter the event.

Attendees can also take part in the congress virtually thanks to support from the Victorian Government.
