You must be worried if someone like me seriously likes  these technical Tools™ which tell us:

• the precise areas / clearances for the different sprinkler types – Ordinary, Light, High
• max spacing between sprinkler heads
• correct max distance from columns / obstructions and other spatial abnormalities.

• when existing buildings are modified & partitions moved / large spaces broken up .
• if only to tell the Client they will be up for making sure existing fire safety is tweaked.
• so you Builders have no excuse for not looking really smart about these technical aspects of good building practice.
