ARE 5.0 - Allowable Building Area for PPD and PA 

Thank you for taking the time to post this. It is very helpful. Been a while since school time. So just reading the equation takes a few times to read.

These videos are great- the best on RU-vid. Other videos from Black Spectacles, Pluralsight, etc. waste so much time with banter, non-ARE related advice, self-promotion, confusing hypos, and often wrong answers to their own questions. Please consider making more- many more- videos.

By the way, I forgot to tell you. I passed PA. Thank you for all of your videos.

Great video! Will definitely be watching your videos!

Thank you for sharing this! Much appreciated!

Thank you so much for all of your videos! What stresses me out the most about this one in particular is, I'm not sure how in the heck would I be able to do this with the whiteboard and the exam's clumsy calculator?!

You rock man!

Thank you 6.38k. Cheers mate

Thank you! This is so well-explained. Any chance you could do (or have done) a video for mixed-occupancy, multistory? Ran into that condition and I'm confused all over again :/

ty sir

Great

Thanks for the video! I wondered why did not we use (S=4 rather than 3) for the number of floors if we are assuming the building to be equipped with a sprinkler system throughout? I think it says in the footnotes that S=3 as a maximum when it is not sprinklered, but 4 if it is. Thanks

I'm trying to solve for Aa for a single occupancy one-story the equation I'm using is 5-1 Aa = At + (NS x If) plugging in the information I have Aa=25,500 + (8,500 x 0.75) = 31,875 ft2 This seems like a lot I just wanted to see if I was missing something, my understand of this is my maximum allowable square ft2 for a single occupancy one-story is 31,875 ft2. Please let me know your thoughts...

Thanks for the video! For the frontage increase calculation, you mentioned you only count those walls whose frontage is greater than 20. Whoever you counted walls C and G whose frontage is equal to 20, but not technically greater than 20. Can you clarify?

Have you ever used the Graphic Standards subscription? Was it useful?

if a building face has an exit stair projecting off the face... do I measure from the face of the building or the stair?

if the property line is at an angle to the building do I measure at the smallest distance from the building

Do the equations in this video still apply to the 2021 IBC?

When calculating the "W" you use 20 and 30, but AHPP page 873 says "W/30 uses the space around the building of between 20 and 60 feet, confused need more explanation.

Why is the allowable area per floor larger than the land area?

How many decimals should you round to in any step of this equation? I noticed in the "F/P - 0.25" step, you rounded to two places for 0.41, but then for the final value of 'If' you ended the decimal at 3 places for 0.375 - is there a particular rule of where to stop? I saw your article online explaining that for calculations of building height, area and stories the rule of thumb is to always round down, so I understand that it was deliberate that 0.375833333 became 0.375 rather than 0.376, but my concern is that: if the 'If' variable in the Single Occupancy Multistory equation had been rounded as 0.37 instead of the longer 0.375, the final value of Aa for max total building area (as well as the max area of any story) would have come out different. Since every point could make a difference and some of the exam questions require you to type in an exact numeric answer, I just want to make sure I'm clear on this procedural stuff in case that could make a difference in them grading my final answer as correct. I don't know if they ever accept a 'range'

I really hope a question this detailed is not in the PPD exam. Dam.

Why 3?

The thought of doing this on the whiteboard is dreadful.
