The cladding debacle
Engineer Chris Stoltz outlined Melbourne's scandalous fires involving cheap PE-filled aluminium cladding on highrise buildings. He explained the causes, the paucity of regulation, how to fix it, what the regulators are now doing. An animated discussion followed - there were 35 in attendance. Chris is President of Engineers Australia and the media's "go-to" man on engineering issues. He spoke passionately about engineers getting on the front foot, communicating clearly, taking a position.
The AGM was also run in near-record time on the same evening. No changes in the Committee; a good year for events, attendances, networking and financially - small surplus, all solvent. Members were also encouraged to send their details to FESA for adding to the list of forensic practitioners published on this website.
July 2017 meeting - two presentations - Truck safety systems, and Traffic cameras - the real story
June 2017 meeting : Fire investigation (2 speakers) - Thursday June 8, Melbourne.
Member Ian Eilenberg spoke on house fires related to (faulty) chimney designs, emphasising flue size, type, and spacing from flammable members. Member Peter Hart spoke on truck and trailer fires - addressing the significance of (flammable) polymer wiring sheathing, giving seven main fire causes (see below), and mentioning difficulties in getting a government response to the industry's advice for tighter standards. Talks were well moderated by Lawrence Reddaway, and a fine meal assisted our networking and discussions.
Experts in court - presentation by lawyer Henry Carus ... Melbourne, 11 May 2017
Henry is an experienced personal injuries lawyer who applies a highly client-oriented determination to the investigation of claims, the appointment and briefing of experts, and to assertive efforts to get the best outcomes he can for his client. He gave a very lively, candid and helpful presentation on how experts should understand their duties to the court, and what a good expert needs to do to prepare, report, and give effective evidence. A very good talk.
Henry, who has described his approach to his opponents as being "pleasantly aggressive", was very well received by a full house in attendance.
Meeting: 5 April 2017
After convivial networking drinks, 36 of us had an excellent dinner at Melbourne's Auburn Hotel - with very good presentations from Robert Francis, a corrosion and coatings specialist with over 40 years’ experience, and Ian Godson of Infracorr (over 25 years in the remedial and corrosion engineering fields, and who has worked on many technically challenging repair projects in Australia and overseas).
Dr Francis' expertise is in corrosion and its mitigation, especially in the area of protective coatings for steelwork for atmospheric environments. His experience also covers ferrous metals, technical training and quality assurance. He edited the publication “Sixty Years of Inorganic Zinc Coatings” in 1998, which was revised and expanded in 2013. He took us through coatings, incompatibilities, treatment, effects of humidity, temperature and inadequate preparation, and the steps to take in a forensic investigation of a failed coating.
Ian Godson gave illustrations of a series of investigations into concrete failure in some challenging parts of the world (from the deep Sahara to marine environments), the latest ground-radar inspection tools, and measures to repair spalling by identifying moisture paths and applying appropriate cathodic protection (impressing the necessary electrical current to a supplementary mesh anode).
Our speakers' Powerpoint presentations are now available on this site (members only page).
Meeting – 24 November 2016
“Traffic accident reconstruction”
25 people attended an excellent presentation by Victoria Police Detective Sergeant Jenelle Mehegan of the Major Collisions Unit and Detective Leading Snr Constable Mick Hardiman of the Motor Vehicle Accident Investigation Unit. They spoke on motor vehicle accident reconstruction, with excellent video, images and other material. Dr Mehegan is an engineer with a PhD in accident analysis and a Masters degree in Engineering (by research). Mick is following a similar path to advanced technical qualifications. They have several years of practical, hands-on experience at accident scenes and at court, which fact became quite evident during the session.
It was agreed with our speakers that this session would not be videoed or recorded (for posting on the website), so that the presentation and discussion could be frank, candid and free-flowing. We are planning to ask future speakers to prepare a website-ready summary of their talk, with images, for distant members.
After convivial FESA-funded drinks at the bar, we listened attentively to the presentation. Dinner was served midway. The material covered ranged across dash-cam evidence (there are many of them in use); red light and integrated speed cameras (likewise!); when the police special investigation units must attend; closing roads; working out directions of travel and impact; calculating initial speeds from projected damage or bodies; tyre marks; vehicle and tyre visible damage interpretation; air bag downloadable data (there’s lots of it); witnesses and their reliability; the weird things some people do; the extraordinary prevalence of methamphetamines in accidents (60% +); obtaining mobile phone traffic data; use of CCTV footage; tough times talking to families of victims; being called out at all hours; how reaction time calculations are being improved; the high burden of proof for prosecutors (“beyond reasonable doubt”) and the unpredictable outcomes from juries; what gets admitted as evidence, and what not.
This was an excellent meeting, and we thanked our presenters (organised by Secretary Adrian Grosvenor) profusely – before sending these two traffic accident specialists on their way with a bottle of wine each. Hmmm!
September 2016 at the Auburn Hotel
AGM and three member presentationsAfter convivial drinks provided at the FESA bar from 6:30, we held the AGM. There were short reports on a successful year, reelection of the Committee, followed by dinner and three very good presentations.
These were practical talks by three of our own members , dealing with real-world forensic issues, methods and solutions.
First up, Barry Clearwater spoke on “Aspects of aviation fuelling, with some Forensic Engineering Aspects”
Bill Contoyannis followed with “Risks associated with access paths – good and bad access” (A case study was used to assess the issues raised when a pedestrian fell and was injured, accessing a path towards her parked vehicle. The expert was asked to comment on the environment where she fell identify the risks associated with the path. The risk of a fall was accepted by the court, however the court ruled that the risk was foreseeable to the Plaintiff, and not necessarily to the Defendant).
Finally, Wayne Baker spoke on "A tale of two chassis - design and maintenance philosophies in heavy vehicle design".
These talks were well received, and discussion was vigorous.
18 August 2016 at the Auburn Hotel
Twenty members attended an interesting 5:30 presentation at Swinburne University's Smart Structures Lab (Hawthorn campus), where two forensic engineers - Prof Emad Gad and Dr Javad Hashemi - demonstrated the facility's state-of-the-art test equipment. More details about the facility are HERE. We then repaired to the nearby Auburn Hotel (the Geebung Polo Club) for 6:30 drinks, dinner and excellent talks from our hosts.
We thank our guests for their hospitality and their very interesting talks.
16 June 2016 at the Auburn Hotel:
Aerial photography and records
First, Patrick Irwin took us through the extensive archival photography resources that cover our world (made before Nearmap and Google).
Patrick provided a summary of a number of aerial photography archives he was able to track down. Mainly for the Victorian attendance, these included the Victorian Department of Planning, Land and Environment, University of Melb Baillieu Library, State Library of Victoria and a couple of others. Archives are of variable quality (HiRes, LowRes, B&W, negatives etc) - mostly images kept in shoe boxes (yep…just like home) and generally poorly catalogued, rarely digitised.On the positive side, he said most collections are “indexed” as is - generally difficult to then drill down and get a particular item. They also have started the process of digitising in some cases.
Jordan Schreuders from Flightcraft then presented the latest technology in drone photography and its application to investigations.
This was a great "show and tell" with lots of very nice toys. Jordan gave a brief history before discussing the types of things his company (Flightcraft.com.au – website being developed) do - mostly building inspections (he does do some advertising and video work as well).
The technology is getting cheaper and more capable BUT – he has the equivalent of a drone pilot's licence - as well as CASA approval etc. It is easy to use the gear, but very difficult coordinating its use with CASA, councils and anyone else who needs to provide approval (neighbours, etc!)
You can do just about anything you would think with a drone, but don’t expect to be able to do it “quickly”, ie without notice.
Other interesting items…you get about 15 minutes' flying time (then replace batteries).
· Varying types of cameras and lenses (zoom, 4k quality, thermal)
· Up to 20 kg payload (changing all of the time – I note a 200kg pay load in today’s paper! !?!
· Full of sensors and smarts.
A sophisticated drone (2-3 kg pay load costs about $10k, then add whatever else you want, for extra $$.
Thanks to Bill Contoyannis for this meeting summary. Our video man was away overseas so regrettably no videos are available for these presentations.
21 April 2016 at the Auburn Hotel
We had an excellent meeting in Hawthorn, Melbourne in April 2016. Here, speakers Peter Paras (engineer) and Suzanne Kirton (barrister) are introduced by FESA President David Lake:
Peter spoke on his firm's sophisticated document preparation and management system:
Suzanne (below) spoke on the practicalities of being an excellent expert:
35 members and guests enjoyed a fine meal, conversations and very good presentations:
Another good FESA meeting on Feb 15:
Materials engineer Dr Adrian Grosvenor spoke on "Large 4-stroke diesel engines - design, manufacture, applications and trouble-shooting".
John Lambert, vehicles expert, spoke compellingly on "Police Pursuits: do they work, and should they be permitted?"
A full video recording of each presentation is available on the members-only page.
