I work for an architectural firm in West Palm Beach, Fl. This information has helped me redesign a ramp for a historic property called house of refuge is Stuart, Fl. Thank you very, very very much for posting quality content. You should be proud of yourself. 😎 I’m subscribing right now…

Thank you! Great information regarding ADA, Ramps and Hanrdrails!

Illustrated and explained ADA Ch 405 well. Thank you

Sharing this with the NCIDQ study group! Thanks! You always think of the best questions and have great explained answers! The graphics are a bonus! Much appreciated.

Thank you. I'm a lic. P.t. in NM & I used this as a reference in a current case situation- very helpful

I'm doing building insections in Saudi Arabia. Your videos are helping a lot in understanding the code requirements. Excellent job

Super helpful video, thank you!

Thank you so much for your services your explanation was outstanding it has helped me tremendously

You always do such a great job in presenting it as well as explaining it. Thank you!!!

Very well explained. Thank you

Nicely done dude thank you

Thanks for the video. You know what you are talking about.

Great vid !

Great job thanks

I renovate hundred year old theaters and appreciate your videos. A large portion of the work is related to ADA requirements.👍👍

Good information!! Thanknyou

Thank you 🤩

My company makes handicapped accessible ramp systems for residential and commercial applications. Thank you for such a great explanation that I can forward to my customers!!!!!!!! You are a great teacher.

Great video..👍

Awesome thorough explanation, my man thank you

Thqnks

@3:34 You cannot have a continual ramp, but you can connect many and chain them, having "lamdings."

Could you address doors preceded or followed by ramps and landing requirements for such cases?

Please can you throw more light on draftstopping, firestopping & fireblocking. Thank you, really appreciate your teachings.

Hello, thanks for these videos, they are really informative. I like the graphics and format you use for the presentation, do you have these videos in paper form, if yes, how can I get a copy?

@archicorner, please also make video on Emergency egress door locking requirements and restrictions. Can Egress doors have lock on it or not? Interface requirements of access control mechanism.

great video! a question about the ramp, if we have the ramp at 36" (which is the min) and also need to add the edge protection which takes up 12"- do we additionally add it after having the 36"?

Hola me gusta 👍🏻.

3:33 Not accurate, you calculated the "shortest possible ramp length for a 30" rise, not the "longest possible ramp length for the ADA rules to still apply." In doing so, there seems to be a bit of confusion caused. First, it is not that you "cannot have a 50' to 100' long ramp for a 30"(inch) rise" it is that if your "ramp" is 50' to 100' in length, the ADA "does not consider such a pathway as a ramp as it is so long for such a short rise, it is not steep enough for the ADA to consider it an obstacle which is rises to the difficulty that neccesitates the "Ramp rules" be applied. For example, in many forests, prairies, etc. raised wooden pathways are often constructed to serve as ADA compliant paths for people to use to enjoy the surrounding nature. These pathways, inevitably shift due to their very nature of being a low impact on nature as possible (light footings, shallow footings, not the strongest foundations) combined with the "nature" of nature to shift, change, etc. especially in the North where freeze/thaw cycles wreak havoc on such structures requiring footings as deep as 5 feet for a stable walkway. This shifting, or even the inclined design of a path to overcome the natural rise in the land it traverses, can result in on end of a section of pathway to be several inches or even feet higher than the other end, especially if the section is over 100' long. To avoid the cost and distraction from view that complying with ADA "ramp rules," these pathways are designed to have a maximum rise of 1:20 thus avoiding the need to comply with the ADA ramp rules. ADA ramp rules apply only to sloping paths that are over 1:20 but less than 1:12, so a 1:19.999... path would be a ramp that needs to comply with these rules. Such a 1:19.999 ramp which traverses a rise of 30 inches would have a slope or rise:run of 30 inches (rise) : 599.99 inches (run) [ 19.999 inches ramp length per 1 inch of ramp height means a 30 inch ramp rise would have a 19.9999*30 inch length or 599.999 inches or just short of 50 feet. Such a ramp is "allowed" but not because the ADA says it is allowed, but because the ADA says such a path is considered a ramp by their applicable definition and thus the ramp rules must be applied. Again, it is not so much what is and is not allowed regarding run lengths that are very long, but what can and is considered a "ramp" per definiion, as once it meets the definition then you have to comply with all those ramp rules. Also, you likely won't find a ramp that is 50' long or longer as they are not generally needed or wanted, either because the ADA rules require flat landings as a place to rest every so often or because such long lengths cannot physically fit on the smaller business lots where these ramps often are needed as retrofits or because at that length, the rise is more likely to be so shallow, the path is not a ramp by definition or some other ADA compliant device, structure, etc. would be a better solution. Your calculation was for the "shortest" possible length of a ramp at 30 inches of rise; A ramp any shorter than 30 feet over a rise of 30" is too steep to comply with ADA ramp rules in general. Again, you can have a ramp that rises 30" be 'longer than" 30 feet. For example a ramp that is 48 feet long and rises 30 inches is a "ramp" per this ADA definition as the rise:run is 30":(40feet*12inches/ft) or 30":480" or 1:16 which is smack in the middle of the 1:12 to 1:20 you discuss at 1:30 in your video. Conversely, if a path is 28 feet long and rises 30 inches would have a rise:run of 30:336/(12*28) or 1:11.2, a slope steeper then the max of 1:12; for rise:run, the "run" number has to be between 12 (steepest slope) and 20 (flattest slope) as if the "rise" number is lower than 12, it is generally too steep to be allowed by the ADA, while if the number is greater than 20, the path is flat enough that it is not considered steep enough to have the ramp rules apply to it.

for straight ramp, required bottom landing to be 72" min

Very Good Information. Question: For the ADA Cross Slope, you use the ratio "1 inch to 48 inches" for ensuring that the Cross Slope is 2%. But "1 inch to 48 inches" ratio is actually 2.08%. How should the '.08' be treated? Should 2.08% be rounded to 2.1% OR is the .08 dropped to get just the 2%? Thank you for your time.

For California, do we use cbc or ADAS or both?

25 inch step. How long should my ramp be?

Thank you!!!

Is there different requirements for a person with a powered wheelchair?

what is the finish required for the steel or aluminum ramps

So i have a 30 inch rise and 20ft of length can that be built as one straight ramp? Or will the slope be to much?

Does a platform under 30" height above grade require a handrail, or just the ramp leading to it?

Great Video! Recently visited a cousin that needs a ramp. She was told it couldn’t be installed on her mobile home because it was to high. I don’t find any limits on height as long as it meets the slope and other requirements. Is there an organization that can help her get a ramp?

Do I need to permit an Ada ramp in California?

Can you design me a skillet ramp for my property 30 feet wide 120 feet long slop 5%

Spanish version???

Why don't you do 8% that the professors told me?

Well! then why this much speed teaching
