Are you on the IPC or UPC?

also, with calculating the waiting room at 1 per 15, the storage & mechanical spaces at 1 per 300 & the remaing clinic area at 1 per 150 (or 1 per 100 depending on what version of the IBC your on) how many occupants do you come up with for each of the 3 occupant load calculations?
IBC. Clinic is 1/100.

I am not sure you need to do anything to your plumbing counts assuming you current show (1) make & (1) female toilet room. Looking back thru your posts you have a 3300 SF clinic with a 479 SF waiting area. Based on that info I am coming up with 32 occupants in the waiting area (479 / 15) & 29 occupants in the remainder of the building (2821 / 100) . I then apply the B occupancy plumbing calculations to the 29 occupants and one of the A3 Occupancy plumbing calculations to the 32 waiting room occupants. Even though the waiting room is technical a B occupancy and not an A3 occupancy, the IPC code commentary is very clear that plumbing fixtures can be calculated this way.

If we are all in agreement with this, I then come up with the following calculations

Water Closets
A3 Male water closets 1 per 125 = 0.13 fixtures
B Male water closets = 0.60 fixtures
Total male water closets = 0.73, rounded up to 1.0

A3 Female water closets 1 per 65 = 0.25 fixtures
B Female water closets = 0.60 fixtures
Total Female water closets = 0.85, rounded up to 1.0


Lavatories

A3 Male lavatories 1 per 200 = 0.08 fixtures
B Male lavatories = 0.38 fixtures
Total male lavatories = 0.46, rounded up to 1.0

A3 Female lavatories 1 per 200 = 0.08 fixtures
B Female lavatories = 0.38 fixtures
Total Female lavatories = 0.46, rounded up to 1.0


Drinking Fountains

A3 Drinking Fountains 1 per 500 = 0.06
B Drinking Fountains 1 per 100 = .29
Total Drinking Fountains = 0.35, rounded up to 1……(Must provide a high & low fixture, minimum of 2 DF required)


So based on my math you need to provide one male and one female toilet room, and 2 drinking fountains to meet the HiLo Requirement

Interesting. I'll look this over.
