May 29th: lawyer Bronwyn Weir on building insurance reforms, and a cladding update.   Her 43 minute recorded Zoom presentation with slides, and its link, have gone by email to financial members, as well as a link to an excellent podcast (highly recommended - listen in your car) of Bronwyn's address.

Navigating Reform and Understanding Defects

Patrick Irwin introduced Bronwyn, highlighting her extensive experience and noting that she had spoken to the group twice before. Her ability to provide a broad, global, and regulatory perspective on the construction industry was noted. Bronwyn is the Managing Director of Weir Legal and Consulting, a role she has held since 2017.  She specialises in advising government regulators, with her expertise in building regulation. In 2017, she co-authored the influential Building Confidence Report with Professor Peter Shergold.  She continues to advise Australian governments on crucial building regulatory matters, including combustible cladding, security of payment, regulating developers, building and materials defects, and enforcement powers. Her advisory work extends beyond construction to sectors including education, health, and water.

Key Topics:

The presentation was structured around two distinct, related key topics. Bronwyn paused between the two sections for questions.

The two key topics were:

1- The move to first resort insurance in Victoria.

2- Research published by Cladding Safety Victoria (CSV).

May 1st - Auburn Hotel - Geoff Fletcher spoke on 

Compliance, Conformance, Certification, Consultant criminality and the Engineering Code of Practice.

The presentation addressed the critical aspects of regulatory compliance and certification for professional engineers in Australia. It draws on recent legal cases and regulatory shifts, with a focus on the building and construction sector.

Here are some key points from the presentation:

· Focus on Regulatory Compliance: Certification is about confirming compliance with regulations, not just client expectations or Australian Standards, unless those standards are specifically referenced in the regulations.

· Australian Consumer Law (ACL): The presentation highlights the importance of the ACL, particularly Section 18 regarding misleading and deceptive conduct, which can apply to engineers even without a direct contract with the affected party.

· Compliance vs. Conformance: Compliance means adhering to regulations, while conformance is about matching design to construction. Both are important, and they are distinct.

· Regulatory Certification: Certification is about complying with building regulations and the National Construction Code (NCC), not just Australian Standards, unless specifically stated.

· Legal Cases: The presentation discusses cases like Mistrina v. Australian Consulting Engineers (ACE) and Actron v. DEEQ Consulting, which illustrate the serious consequences of defective certification and the engineer's responsibility for regulatory compliance.

· Personal Risk and PI Insurance: Engineers face significant personal and professional risks, and Professional Indemnity (PI) insurance may not cover intentional wrongdoing or criminal acts.

· Importance of Being Informed: Engineers must actively seek out and understand relevant regulations, acts, and court judgments.

· Key Takeaway: Regulatory certification is about demonstrating compliance with the law (regulations and the NCC), and when an engineer certifies, they claim to comply, and others have a right to rely on that certification.

In essence, the presentation emphasized the shift towards stricter enforcement and accountability for engineers, stressing the need for diligence in understanding and applying regulations.

FESA Zoom Meeting on Lightning Strike and Power Surge Events - 27th March 2025

Presenter: Grant Gatland, Committee Member (Envista Forensics Electrical / Mechanical investigation team). Lightning strike and power surge events, differentiation, damage assessment, and implications for insurance claims.

Executive Summary:

This briefing document summarises the key themes and information presented by Grant Gatland during a FESA Zoom meeting focused on lightning strike and power surge events. The presentation aimed to educate FESA members on the differences between these events, the types of damage they cause, methods for validating claims, common myths, and the complexities involved in assessing related losses. Gatland drew upon his extensive experience in investigating technical loss events for the insurance industry. A significant emphasis was placed on identifying genuine lightning or power surge damage versus alternative causes, including potential fraudulent claims.

Key Themes and Important Ideas/Facts:

1. Importance for Insurers:

●      The primary driver for understanding the nuances between lightning strikes and power surges is for accurate validation of insurance claims.

●      Distinguishing the cause of damage is crucial for determining policy coverage, as some policies may exclude power surge damage while covering lightning strikes.

●      The financial implications can be substantial.

2. Defining Lightning and Power Surges:

●      Lightning: Described as a "giant spark" that occurs between charged regions in the atmosphere (clouds, air, and ground). It involves a stepped leader of negative charges meeting a streamer of positive charges from the ground, resulting in a high-current discharge (ranging from 5,000 to 200,000 amps).

●      Power Surge: Primarily defined as a "voltage spike" that can be caused by nearby lightning (through inductive coupling) or other events like transformer failures. Gatland clarified that a power surge isn't typically just an increase in current; it requires a voltage increase.

3. Differentiating Damage:

●      Lightning Strike (Direct): Causes intense heat and current, potentially leading to physical damage like trees being blown apart, brickwork fracturing, and burn patterns along the current path.

●      Validation involves looking for a "path to earth" from the point of impact, although this isn't always obvious.

●      "Small pinhole-type damage" can occur on metal objects.

●      Power Surge (Inductive Coupling from Lightning): Large magnetic fields produced by a nearby lightning strike can "inductively transfer energy and induce voltages into other conductors," particularly long runs of low-voltage wiring (e.g., telecommunications, security systems).

●      Damage often manifests as a failure of connected equipment due to high voltage spikes, potentially affecting multiple devices but not always.

●      A key indicator is damage not originating from the power supply side of the circuit but directly impacting the low-voltage wiring.

●      Physical burning damage is less common; instead, components like chips may "blow apart" without prior heating marks.

●      Power Surge (Other Causes): While the presentation focused on lightning-induced surges, Gatland briefly mentioned transformer failures as another potential cause, typically resulting in a sustained voltage increase rather than a rapid spike.

4. Common Myths Debunked:

●      "Lightning will always cause a circuit breaker to trip."

●      "Lightning will always leave a boom hack behind on electronic components."

●      "If one item's damaged and others are saved, then it should be a power surge rather than lightning."

●      "Lightning doesn't strike twice." (Gatland highlighted Kuala Lumpur International Tower as a location frequently struck).

●      "Equipment damaged by lightning so it can't be repaired or if it is repaired, it won't be reliable."

●      "Impossible to distinguish between lightning and power sage."

5. Latent Damage:

The concept of latent damage from lightning (failure occurring weeks or months after an event with no immediate signs) is generally not supported by Gatland's experience.

If damage is going to occur, it "usually will develop within a matter of days and not outside about a month or so."

6. Equipment Vulnerability:

●      Network and telecommunications equipment, AC equipment on rooftops, long-running low-voltage cables, fire alarm systems, elevators, and security camera/card access systems are particularly vulnerable to both direct lightning strikes and inductively coupled power surges.

●      Power supplies often have built-in protection (Metal Oxide Varistors - MOVs) against typical power surges but may not withstand direct or severe lightning-induced surges.

●      High-voltage power transmission networks have lightning arrestors to protect their infrastructure.

7. Prevention and Protection:

●      Lightning protection systems (lightning rods, earthing) are primarily designed to prevent structural damage to buildings by providing a path to the ground. They may not prevent damage to internal equipment from induced surges.

●      Surge protectors at the power supply level can offer protection against voltage increases and milder power surges but may not be effective against extreme lightning-induced spikes.

●      Building grounding systems (multiple earth neutral - MEN) are primarily for safety (tripping circuit breakers in fault conditions) and not for diverting lightning strikes.

8. Fraudulent Claims:

●      Gatland presented case studies illustrating potential fraudulent claim attempts, where damage appeared to be caused by deliberate heat application (e.g., with a cigarette lighter) to mimic electrical failure rather than a lightning or power surge event.

●      Close examination of damage patterns, such as the melting of plastic components without corresponding electrical failure indicators, can raise suspicion.

9. Tools for Validation:

●      Online lightning detection services (Gatland mentioned TOA as a provider) can provide historical data on lightning strikes in a specific area, helping to verify if a lightning event occurred at the claimed time and location.

●      Analysis of the proximity and intensity of recorded strikes is crucial in assessing the plausibility of a lightning-related claim.

Quotes:

●      "A power surge is really another word for a voltage spike." - Grant Gatland clarifying the definition of a power surge.

●      "Latent damage from lightning - It's seldom something that occurs and what we find is that if it is going to occur, it usually will develop within a matter of days and not outside about a month or so." - Grant Gatland on the improbability of long-term latent damage.

Conclusion:

The presentation provided valuable insights for engineers dealing with lightning strikes and power surge events. He effectively differentiated between the causes and types of damage associated with each, highlighted common misconceptions, and emphasised the importance of thorough investigation and the use of available tools for investigation. The discussion also touched upon the potential for fraudulent claims, urging vigilance in assessing damage patterns. Understanding these distinctions is critical for accurate assessment to ensure the proper outcomes for both insurers and policyholders.

October 24 - injuries to young workers

Engineer Roger Lewis spoke on young workers (under 25 years of age) who are over-represented in serious injuries in the construction and manufacturing sectors, noting that the injury rates to young workers have increased since 2016.

               

This presentation examined three construction-related case studies, identifying common and systemic causes, and describing inexpensive measures that would likely have prevented the incidents from occurring. 

1.      Nail gun incident with loss of eye;

2.      Circular saw kick-back and amputation:

3.      Fall from an unstable work platform.

Using the lessons from the case studies, a strategy was presented to help unravel the full circumstances of a young worker’s injury.  It emphasises identifying gaps in training, supervision, tool selection and systems of work – and how a prudent employer of young workers should diligently control the higher risks faced by such workers.

26 August 2024:

  Rescue of 41 Indian miners

Prof Arnold Dix  ("scientist, lawyer and tunnel guy")  gave a fabulous presentation at the Auburn Hotel Hawthorn of this extraordinary rescue, seen around the world in 2023.  The presentation was hugely informative, entertaining and encouraging.   Arnold is President of the International Tunnelling and Underground Space Association – representing the interests of more than 100,000 global subject matter experts and 81 Member nations as the world’s peak Underground NGO to the United Nations.

Arnold  outlined the basics of tunnel rescues generally, the behaviour of mountains, and spoke persuasively on important non-technical attitudes and behaviours appropriate to engineers working on any problem involving other people.   He urged us as engineers to "Get out and talk to the people affected", " Just DO IT, don't hang back"; "focus on the problem - put all other noise aside"; and in particular, to "be aware of and carefully consider your instincts" - ie treat seriously the wisdom, "sensing" and experience that you feel, apart from your rational deductions.  (Session recording details: see below)

Arnold is a great communicator -  a man who humbly links his redoubtable skills as an engineer, barrister and geologist with practical attitudes that inform his work, his hobbies and numerous activities.  For example, in relation to working on a rescue or a similar problem with others, he said -

Things are never like it is in the movies

Everyone is clever in retrospect

You never have enough information to make a perfect decision

No “one” person saves anyone – it Is always a team

Things always take much longer than expected (even if you expected it would take longer)

You always have to make do with what you’ve got

Information includes “instinct”

Learn lessons – be humble.

This was one of our best sessions yet. 

Session recording: a recording in four parts (totalling about 78 minutes, with plenty of of TV and other clips) is here: on the FESA members-only page ( - follow that link - the page is configured to restrict access to financial members, who are entitled to recordings).   Please raise any questions about your membership status with Sara Abbasi.

20 June 2024:  Legal changes affecting building practitioners and engineers

55 people attended a highly informative presentation by lawyer Bronwyn Weir, a leading authority on building regulation nationally, and an advisor to government regulators.   In 2017 she co-authored the  Building Confidence Report (Google it) with Prof Peter Shergold;  it remains an influential report on policy development.

Bronwyn advises on building regulatory matters including the impact of combustible cladding, security of payment, regulating developers, apartment defects, product safety and the exercise of enforcement powers.

She presented a highly informative account of the emerging engineers' registration schemes, state by state, and the new property developer accountability scheme in the ACT.  She dealt with key features of the NSW Engineers'  Practice Standard which will take effect in September 2024.  Finally, she updated us on her second case study for the NSW Building Commissioner, Broken Promises,  Blame Games, balconies.

Bronwyn's Powerpoint set is now available (click here).  This brings up the front page. You may need to click the little icon at the left of "Page 1 of 21" to start it.  

The recorded presentation (of 75 minutes) has also been posted on Youtube, in 4 consecutive segments (of 11, 30, 16 and 29 minutes).  Go to youtube.com and search for FESA June 24.  Scroll down and you will find FESA 24 Bronwyn Weir 1 of 4.  Start there.

An apology:  issues at the venue (one non-working screen, a flat microphone) made recording difficult, and we could not put Bronwyn's Powerpoint up simultaneously with her address.  No great matter). 

Lots of networking and conviviality made this a great night:

Next month: a Zoom meeting, then in August, a presentation at the Hawthorn pub dinner by Prof Arnold Dix. a very interesting and creative problem solver who was recently centrally involved in the rescue of miners in India.

October 2023 - building collapse and lessons for engineers

FESA member Geoff Fletcher spoke on the 2013 collapse of a multi-storey building in Dhaka, Bangladesh.  34 members and guests were present at this interesting talk, which was preceded by our AGM.

The collapse killed over 1,100 people and injured some 2,500.  It is claimed to be the deadliest accidental structural failure in modern history.  Geoff, an engineer, outlined incompetence, shortcuts, greed, lack of review, and third world low-paid garment manufacture factory stacking,  But just what does "accidental" mean? Numerous people faced murder charges as a result, from a litany of failures - negligence, recklessness and corruption in administrative, design, construction and operational controls. The public suffered - and their need for engineering competence and ethics (in any discipline) has never been so great!

Geoff's main takeaways for ALL engineers were these:

• Check your own character before starting your calculations and computer!  Uncompromised ethical standards are always paramount.
• No “something” is better than a bad “something”!
• Be careful with whom you get into bed!
• NEVER fear inspection / verification / 3rd party reviews. Encourage it!
• NEVER progress past an unexplained, unsolved problem.
• You mght get away with breaking the laws of the State, but never the laws of physics.
• You get not what you EXPECT, but what you INSPECT.
• Imagine one day being cross-examined in Court re your actions!

A good evening of networking  and a fine meal rounded things out well.  The presentation was professionally recorded and is available here now.

21 September 2023

Dr Reza Javaherdashti spoke to FESA via Zoom on 21 September (from Croatia) on Microbiologically influenced corrosion (MIC), with a focus on off-shore engineering due to its importance for Australian industry.  MIC refers to the influence of micro/ macro-organisms on the kinetics of corrosion processes on metals, caused by adhering to the interfaces (usually referred to as “biofilms”-which, in fact, is a wrong terminology).

The presentation focussed on the necessity of understanding MIC mechanisms as per API 580/581 and how forensic engineering methods may or may not be useful in dealing with failures stemming from MIC mechanisms. During the presentation, some interesting aspects of MIC (such as EMIC) which are very important to interpret high corrosion rates were presented.

Some facts and figures about its importance from a corrosion science and engineering point of view as well as the names of some important bacteria associated with MIC were briefly explained.

A one-hour recording of the presentation is here.  If needed, the Passcode is tGb1E^cz

27 April 2023:

Engineer Ted Metcalfe delivered a presentation to 30 present on Professionalism, Ethics and Protecting the Public

Ted explained the tradition of the Iron Ring and other reasons why professional engineering practice is different in Australia from that in Canada.  He presented some of the findings from his study of failure of Complex Engineered Systems, using the Dreamworld Tragedy and the Longford Gas Plant Explosion to illustrate the role of Royal Commissions and Coronial Inquiries in learning for engineers. (It’s usually not engineering incompetence that causes the failure).  He went on to describe the recurring role of systemic regulatory failures, the consequences of commercial pressures on engineering outcomes, and gave an overview of the continuing importance of Professionalism and Ethics.

Lively question and discussion spells covered a range of interesting themes.

The session was recorded in two parts.  The sound is pretty average, but the screen displays are very clear.  Some shaky amateur camera work, too.   Just turn up the volume, and you'll get the whole presentation.

Part 1 (26 minutes) is here.

Part 2 (also 26 minutes) is here.

Australia’s Regulatory Structure for the Safety of Equipment Supplied to the Market

Jean-Marie Ntahonkiriye, Senior Engineer 

Market Intelligence and Enforcement,  Energy Safe Victoria (ESV).

and Dr Peter Hart,  ATTAR.

This ZOOM presentation was rescheduled to Thursday 30 March (5:30 pm) and described the regulatory structure that applies to equipment that is supplied to the Australian market.  It was mainly about Australia’s regulation of low voltage electrical equipment.  First, FESA member Peter Hart (below) gave a brief overview of the regulatory structure as it applies to consumer goods, plant equipment, mechanical equipment intended to be installed in buildings and on and off road vehicles.

Peter then introduced Jean-Marie Ntahonkiriye of ESV, who provided a detailed presentation focusing on low voltage electrical equipment.

The House with No Piers

Lawyer Bronwyn Weir gave a presentation applauded by all 56 present.  She spoke passionately about a report she authored for the NSW Building Commissioner, detailing details of the ordeal of a couple who built a home in rural NSW in 2009.

  

Premature cracking in the walls led them into a initiating a dispute in NCAT which consumed them for almost five years. One of the key issues on which expert evidence was given was whether piers had been constructed as documented in the approved engineering design.  The court accepted the builder and his expert engineers’ evidence that the piers had indeed been constructed, and the court found against the owners.  They were ordered to pay the builder’s costs which together with their own costs were in excess of $300K.  They appealed and lost.  As the matter was concluding David Chandler was appointed as the first NSW Building Commissioner.  They told him their story and he visited their home, during which time a comprehensive excavation was carried out to show that in fact no piers had ever been constructed.  Chandler was determined to shine a light on what had happened to these people and hence the report was commissioned.  The system failed these owners.  The conduct of some of those involved lacked competency and integrity – a hallmark of the state of Australia building and construction industry.

Bronwyn discussed these during her presentation, providing a snapshot of where building regulatory reforms are at, five years on from the Building Confidence Report. Animated discussion followed, expressing dismay with the system, with the evident incompetence and lack of integrity of some of the lawyers and enginners.  The builder was deregistered.

Bronwyn Weir has been a lawyer for 25 years. She runs a small legal practice advising all levels of government on regulatory and compliance matters.

Our 56 guests had a cracking night.  Lots of connections.

A recording of the presentation (57 minutes) is available here.   Note:  the tail end of Bronwyn's talk is in this separate file.  Her complete Powerpoint slide presentation is here.

We have also received Basic Expert's presentation by Jonathan Barnett, Jonathan Duler and Oscar Salt  on lithium ion batteries and electric car fires.

24 November 2022: four great presentations, and our AGM

44 members and guests met for convivial drinks at the Auburn Hotel, Hawthorn, Melbourne. 

The AGM was then run efficiently over just a few minutes.  No elections were due.  In his report (here), President Patrick Irwin announced the cessation of the "Corporate" member category, and the benefits to members by replacing it with conventional membership status.   The accounts were received and adopted (click here to read them).

Thanks were extended to all office bearers, especially hard-working Secretary Geoff Fletcher, and member Mark Dohrmann, who was presented with FESA Life Membership for his 23 years' continuous service to the Committee on backroom membership management, our website and communications.

Four excellent short presentations followed.  

Robust discussion followed each speaker.  Click on their name to see their talk - they vary from 8 to 14 minutes.

Peter Hart outlined cases where a truck chassis rail had failed in different ways.  Scary!  And poor design by major manufacturers.

Nick Jenkins described elevators and the obligations of designers under the Plant Regulations.  Getting stuck in a door is problematic, but not illegal.

Patrick Irwin explained the fortuitous discovery of key facts in preparing a building case involving millions of dollars, and what ethical and professional steps needed to be taken to revise his opinion and so assist the court.

John Culvenor warned us about the Government's "free" program offering incandescent light replacement  with LEDs.  There's no obligation on suppliers to ensure that light levels and quality are retained.  Look for lumen equivalence, not wattage.

The usual good hotel menu pleased the throng:

 

Coffee followed, with much conversation, meetings and getting to know people.  A happy and safe Christmas was wished for all members and their families.

27 October 2022: Electric Vehicles - fire safety challenge 

Three speakers from Basic Expert presented to 34 members and guests on the global problem of fires in electric vehicles - lithium ion batteries being the cause.  Whether charging, driving or just parked, these fires occur.  The passage of time increases the degradation of the batteries and the likelihood of spontaneous combustion.  Fires cannot be extinguished with water, and create an inflammable vapour cloud.  Events are under-reported (there is an average of seven EV fires a day in China) with zero literature, data, guidance, time, or money to do more … this topic is relevant to any practitioner with an interest in risk, engineering failures, or the safety of our built environment… 

The speakers - Jonathan Duler, Oscar Salt and Jonathan Barnett - covered the historical context of how EVs have slotted into our built environment and lifestyles, but how badly this has gone wrong, by way of case studies for some particularly severe incidents. 

The recording of the presentation (1 hr 10 minutes) is too big to load on to this site, but we hope to soon have a link here to the presenters' slides, and which you can access. 

Cyber crime, fraud and forensics

29 September 2022 

Jason Conley of Envista Forensics , a forensic examiner since 2003, gave a very interesting presentation on the characteristics of cyber threats and investigation procedures, with examples.  Jason's accounts of industrial espionage, intellectual property theft issues, breach of contract and fraud-related investigations dealt with spam, phishing and theft, with tips on risk management.  He presented to FESA from London - a great effort in the early hours.

Recordings of the presentation are available here (note the passcode for each)

Expert Evidence - August 25 2022

An excellent meeting at the Auburn Hotel, Hawthorn, with an outstanding presentation by Justice Jim Delaney (Victorian Supreme Court) on Expert Evidence. 

Jim spoke clearly, concisely and authoritatively about all relevant aspects of experts' taking instructions, report writing, hot-tubbing, conclaving, and giving evidence at court.  His talk was filled with tips and practical examples.  An  excellent and lengthy question and answer session followed.

 

The meeting was very well attended, with extensive networking and introductions.  Welcome to all new members!

You can download Jim Delaney's 44 minute presentation here (His Honour preferred not to have the questions section recorded).

July 28 2022 (by Zoom): a presentation by Mark Roberts BEng(Hons), MIET, SAE-A on the subject 

The Humble 12V Battery - Friend or Foe? 

Mark presented on the humble 12V lead-acid AGM battery. Whether you drive a fancy electric vehicle or the traditional internal combustion version, chances are you have owned or had the pleasure of replacing one of these batteries before. But are they more than just a giant AA battery?  Mark covered the unique intricacies of 12V AGM batties and, in particular, what transpires when your vehicle's 12V lead-acid battery is pushed beyond its normal operating conditions.  As dangerous as its lithium cousin?... there's potential!     

Prior to his indoctrination into the forensics engineering industry, Mark functioned as a 12V & 48V Energy Management Engineer within Bentley Motors in the United Kingdom.   Responsible for the integration and project management of all 12V Energy Containers and 48V Supercapacitors within Bentley's ICE and PHEV vehicle architectures, Mark spent the majority of his time in Germany and Sweden, prototyping and validating future vehicle projects.
