Question asked during seminar
My hotel needsd FC every year because it exceeded 200 persons. If I
apply the new calculation then I need not apply FC anymore, how
should I go about in getting exemption?
There is no exemption unless a plan submission is resubmitted and
the building has to comply with the current requirement. The
calculation shall be basing on each room not basing on the whole floorarea i.e. refers to slide 33 showing the hotel flr plan, each room shall
have the its respective area to divide by the OL factor, this includes all
usage like toilet, and with any decimal place it shall be brought forward
to the next nearest number, from there sum up every individual room
to obtain the total floor OL. Also, pls note that a minimum of 2 personsper room shall apply if the OL for each room is less than 2.
