Door Encroachment 18-0
Вставка
- Опубліковано 18 вер 2024
- The distance a door is allowed to encroach into a hallway/corridor/exit way or path of travel out of the building. If a door opens on to a required exit width this video talks to how much it's allowed to encroach. 7 inches is the max when the door is in its fully open position that it's allowed to encroach. Otherwise if the door opens 180° the radius in which it opens that radius cannot encroach more than one half during that swing.These videos are to understand building code
Marty Huie is seriously the best resource I have used for all of my ARE studying, so much better than Black Spectacles
Likewise. Very simple expalanations
Side note, love the fact you are using fountain pens to sketch and write. Lamy has best built/quality and I love their holding barrel - corrected my writing issues. I wish more people in the design industry could appreciate fine writing instruments.
Anyhoo, nice videos! I find sketching things out help me remember specific dimensions much better than simply reading it from a paragraph.
not 37" but 22", the door swing should not reduce 1/2 of the required width which is 44", that makes it 22" not 37". The 7" maximum protrusion is only when it swings all the way to the 180 degree angle.
This is great. Thank you. Suggestion: include source of the numbers. Because that number might change at the next code change.
Thanks for posting these videos!
Thank You for the thank YOU :) don't get many and they are always appreciate. Please tell others of these videos. If you have any other topics please let me know
Super helpful, thanks!
Thank you for posting this.
NFPA 101 requires min 36-inch width and ABA requires min 36-inch or 48-inch width at corridor. Generally, overlap between door swing and corridor is better the 6-inch for construction error.
take a look at 2012 NFPA 101 7.2.1.2.3.2 This has not changed ever
Thank you very much!!
thanks for explanation
sorry for another off-topic comment, but you would love an architect grind for your block letters! Stubs on your Lamy joy are great too!
Thank for explaining! The 2021 IBC section 1005.7.1 has an exception to void 7". It mentioned "surface-mounted latch release hardware". I searched Internet but can't find a good definition about how this type of hardware works. Do you have any input on this? Thank you,
Can y you please provide the commentary for I-2 (healthcare) or refer to another video if one is created?
When the corridor is wider than 44" by code [in group E or other occupancy where the occupancy needs a wider width may be 72" or 96"] the rule remains the same I assume. So the overlap would be allowable to a 7" in that case too. Can you please confirm? Am looking at table IBC 2018 1020.2 Min. Corridor widths. So instead of the 44" min required the corridor would need to be wider like a 72" and then the door can swing out into the corridor.
Correct, the hospital for instance requires a Corredor to be a minimum of 8 feet and a door cannot swing into that 8 feet at all
@@MartyHuie so in that case the door swing when fully open position would be beyond the 8'-0" that makes the corridor a minimum of 8'-7" to accommodate for the door if it has 7" like you had shown in your video.
@@PrithwirajGhoshRoy it's a bit more complicated than that, for healthcare the door is not allowed to swing into the Corredor with at all so the door would have to be fully recessed for schools on the other hand, you would be allowed to swing the door into the Corredor regardless of the width and yes with schools the requied width is 5' I think and there for the door can not cut into the required width by more than 1/2 so with schools and even a 4' door that is not going to happen. but even with the door fully open it can not stick out into the corridor more than 7"
@@MartyHuie Ah makes sense. Thanks for the clarification. Another question based on dead end: Looking at Dead Corridors, can some one shine some light on item 3 on
So if the building that is sprinklered and the the corridor is lets say 8' wide in a non IBC2018 1024.4 Dead end. Healthcare occupancy [Health care needs 96" min by code], in that case the length of the dead end can be 2.5X 8' = 20'. So does this mean the 3rd item is redundant? Since in other kinds of occupancy, the allowable length of the dead corridor is 50'-0"? I am confused. Can some one clarify this?
@@PrithwirajGhoshRoy for healthcare, if you're within the United States that 2.5 does not necessarily work for NFPA does not recognize that and you have to follow NFPA also when doing healthcare in the United States. Really that 2.5 is for areas such as very large lobbies and or breakout spaces that may be 50 or 75 feet long you can use that calculation to say you do not have a dead end
If the building is provided with automatic sprinkler system, the encroachment can be neglected.
Please provide reference so we all can learn I don't believe this is correct at all yet I have been wrong many times before
