The structural members in question were steel, not aluminium.
The original costings were done assuming welded joints. It was a contractor who cavilled that expense, and the change to bolted joints was done without notice to the lead engineer.
What you describe does happen, I've seen it in the field of software; but it's not the issue described in TFA.
- repelsteeltje 3y agoThis is all true, and I admit using to big a brush here. And sorry for my inaccuracies. I meant to look as the process more holistically. Yes, I think you're precise in point out this was not a planning / engineering issue, but execution. But stepping away from the finger pointing; there is always a disconnect between the actual physical building and the model, assumptions conjured to guide the physical process toward safety. A welded joints on paper are neither safe or unsafe; it's the physical result that requires the safety. It seems that somewhere in the process the architect/designer, engineer, supervisor, builder, hadn't paid attention. And without blaming one or the other, there are always (political) motivations for people to look away. That is, it's difficult to get a man to appreciate a problem when his salary depends on his not understanding it. :-)
