I've hit a wall trying to create a schedule that automatically determines your minimum plumbing fixture counts based on the IBC. I've searched the forum and can't find this particular answer but know many of you must have gotten this far.
Here it is:
Plumbing code defines # of required fixtures per use group. For example, Use Group A-1 requires 1 Male Watercloset per 125 occupants.
So, first I created a key schedule that defines the associated rules for each use group (see attached).
Then I assigned a key (use group) to each area on my area plan.
Then I created a schedule that totals the number of occupants for each use group type and divides that by the associated # from the key schedule. (see attached).
But, when I get to Use Group B, I hit a wall I can't figure a workaround for.
The requirements for that group are not simply 1 in 125, but "1 per 25 for first 50 occupants and 1 per 50 for remaining occupants exceeding 50". Ugh.
If there is no workaround, we'll simply export a schedule to excel that tallied the # of occupants per use group - that in itself is a big help.
Thank you,
