    I have total confidence in the honesty and integrity of the consultants wanting to do their job as expected of their profession. Their traditional “position of authority” has been effectively taken away, however, if they are left vulnerable to progress payments from the builder to practice...

    It would be good to have a Part 2 of the Final Report, with a follow up on the rectification work. It’s not bad that there will be further checks in place on the professionals, but I think that is the easy and more politically palatable route. The harder issue to deal with is that the...

    Just curious- is there something that’s stopping them from making the loads go directly down via new intermediate columns through the whole garden slot areas. (To effectively continue the columns down throughout all the levels) Rather than sticking with the transfer beam scheme. In terms of...

    Thank goodness for whistle blowers. Here’s a link to the ACA clip:- https://www.9news.com.au/2019/02/04/16/36/opal-tower-exclusive-video-construction-cracks-cement?ocid=Social-ACA

    I am also wondering when the professors’ final report will be issued, especially since people have already started re-occupying the premises. It would give them a certain level of comfort if an independent public authority confirms the process. This is after all, a defective structure built...

    Have they used some kind of structural epoxy adhesive injected into the cracks? I wonder what they found about the reo in all the other panels. Apparently there’s a “concrete scanning” service that uses ground penetrating radar (GPR) technology to locate reinforcement. Not sure whether the...

    Yes, you're right MDEAus. That photo is in the interim report. Thanks for that.

    "The Urban Developer" website has an article by Ted Tabet dated 21st January 2019 that seems to have a new photo of cracks on the upstand beam. It doesn't state what area or level this photo was taken at. Here's the link to the article:-...

    SBS World News managed to obtain Cardno’s letter to the owners, explaining their current professional opinion. https://www.sbs.com.au/news/opal-tower-body-corporate-warns-against-return-amid-calls-for-building-industry-audit The text was a bit blurry from the video, so I’ve typed out what I...

    The news reports mentioned “remediation” and “stabilisation” works that were scheduled to be completed last Friday. This suggests works to the structure, which is why they have all the heavy duty props, while those are carried out. This is speculation- but perhaps they need the 4-6 weeks for...

    You might be on to something CivilEngAus. It would be good if the construction programme was checked against when the concrete slab would be cured/ robust enough before it’s subjected to various loads eg. Load bearing panels, post tensioning, and also checked against weather conditions. I’ve...

    Wow, sounds like a structural engineering soap opera! Thanks rscassar for your reply on the 31st Dec 2018. I appreciate that. I learnt a lot from your comments too, SheerForceEng. Your explanations are very clear and thorough, and it’s great to have someone with your experience sharing your...

    Thanks for your response human909. I really appreciate that and hope you get better soon! I was thinking that perhaps there was a sequence of failures that started off with the post tensioning that led the floor to crack and drop 40-50mm, which in turn damaged the precast wall above it. This is...

    Hi, I was wondering what everyone thinks of this theory:- The “transfer beam” is a concrete upstand beam that it acts both as a beam and as the planter wall. (When you look at the balcony photo, the top of the beam that runs along the apartment wall should align with the top of the planter hob...
