Meeting: 21 February 2019, Melbourne
46 people attended at The Auburn Hotel. Convivial drinks, introductions and conversations took us to the table where we heard two excellent presentations over dinner.
Don Considine spoke on moisture related flooring failures - a multi-million dollar Australian problem. Don is an experienced carpet, floor and coverings consultant with a great breadth of knowledge. He covered a wide range of practical material dealinfg with concrete slabs, carpet, vinyl and timber. Test methods and the importance of testing floors (new and old) was stressed.
Dr David Morris spoke on learning from the failure of cantilever sign gantries in Victoria. David is a consulting civil engineer active in forensic work. Various failure exampkes underscored David's insistence that engineers do not slavishly assume that "compliance with a Code" means a satisfactory design. Engineering judgement is essential - how does a Code apply? Or which parts?
Afine meal and drinks were enjoyed by all present -

30 members and guests attended our AGM and enjoyed two good presentations over dinner at the Auburn Hotel, Hawthorn.
Electrical engineer Peter Hart spoke on solar panels.
Peter covered how inverters work; how much energy is available and how much can be captured; technical standards and the CEC, the accreditation of installers, feed-in tariffs. Problems were outlined, and they are significant - inverter failures, isolation switch failures and panel shorting to ground. Limits to achievable energy outputs were outlined, and an explanation of how the Tesla Powerwall and its Gateway work. His summary points were -
Engineer Richard Lightfoot next presented three case histories on interlocking system failures - all illustrating an evident failure by the designers to think through what users might actually do - thus, where to put the relevant sensor, when a second sensor was advisable, etc.
