Yep. But as far as the opening question as to who / what garners the blame (parents or the design)... John Portman's design of the rotating restaurant is potentially exonerated if placement of the tables was a variable delegated to later interior coordinators that owners / management hired and whose choices safety inspectors approved. Or if he did specify strict placement of furniture in the original plans (and such was spaced sufficiently wide and went unchanged for 37 years), then responsibility shifts to the 2013 renovation crew for changing the scheme; or to management and safety consultants for approving their narrower alteration.
Standard safety question
Are / were there any legal safety standard requirements at time of
ORIGINAL construction?
Did the
ORIGINAL plan and construction pass all the applicable standards?
Were there any changes to
ORIGINAL standards which were mandatory to implement?
Were the renovations approved to take into account any updated legal safety requirements?
And a few biggies
IF safety standards were present
WERE THEY SUFFICIENT?
WHO (if anybody) is / was responding for maintaining any safety requirements?
WERE unauthorised changes made to the layout which compromised safety?
How much training is / was given to personnel about safety and importance of obtaining permission or at least checking with safety officer about proposed changes?
There is much more involved
BUT
frequently overlooked are the following
What can we learn from this?
How can we prevent this happening again?
Are there any other surprises out there?
