Different organization have different ways of work. The current will only READ debriefs from the past committee or hopefully there are long time stuff running the event year in and year out to see such problem. They are not public, so they don't see problems u see. If there is any hardcore issue, write to them and feedback on public's point of view, let them have your words as historical moments and feedback for them to learn and execute and solve the issue for you. Writing and screaming here can only let those without power but talk only people see... and we will take it as reading gallery to kill time...
Whether the bridge collapse or the safe working load is longer than HDB or can last thousand years, let the expert talk. I'm no expert in this, but I know and believe Murphy's Law.
If there is a need for everything to be explain, i guess we have to look for it ourselves or even ask the organizing committee to explain if there is chance.
Since it may be last minute, then they will have to work last minute way... if there is supplier willing to print and mount those notice last minute, do recommend to the organizing committee, so they know who to look for if there are such cases going on or repeated..
