Genoa bridge collapse

Another thought just occurred.

Modern cars really are getting on for twice the weight of cars from the 60's (As are Lorries)

Like with that 60's multistory that collapsed a while ago. The deck loading could, under congested conditions, be far greater than might originally have been planned for.

Which is why structural assessments should be carried out.
Also if designed properly in the first place you tend to add a bit of 'fat' for future proofing. This is in addition to other standard design and safety factors that are built in.

This is why, for example, a concrete structure I'm currently designing is specified for a loading of 15 tonnes per square metre but in actual fact it'll take 25 comfortably.

Absolutely, I design circuit boards and depending on type of component we derate to 60% to 70% to ensure reliability and additional margin. I would expect any engineer to do the same whatever the field, safety critical or not
