Well not sure whether he was reading correctly or creating issues. We have escalated issue to higher management and then office of city council. They have many inconsistencies in their reply so finally they were able to remove fire sprinkler requirement.
However, there is another requirement which was put by building guy and we need your guy help.
So building guy has put 1 hr fire wall requirement for one side of house wall ( This is SFR but one side of neighbor fence is 3.1 feet) so according to him we need to have 1 hr firewall. Our architect did not put this requirement but he wrote down manually on approved plan.
We are not doing any exterior changes, just interior so according to him 1 hrs firewall ( Type X sheetrock inside ) and Type X sheetrock outside. Outside one is problem since we have to take out all sidings etc.
I have found one product called fireguard E 84 which can provide 1 hr firewall inside and outside
https://shieldindustries.com/product/fireguard-e-84/
But building guy is saying "Since this product is a non-conventional approach to a code compliance issue, it you would need to apply for a AMMR, Alternate Methods & Materials Request and blah blah ...."
So according to him I need to have method get approved.
I am assuming that there is not only a single way to tackle issue but should be various cost effective ways
Does any one know how to tackle this one hr firewall problem without taking out outside ( sidings etc) ?
Thanks a lot.
