Are micro-dots on truncated domes code compliant?

[Yikes]

I received this at a shop drawing submittal for truncated domes.
https://armor-tile.com/assets/ada-c-3648w.pdf
It shows multiple "micro-dots" both on the domes and between the domes, and the micro-dots are described elsewhere on plans as 0.1875" dia. x 0.0625" high. I presume these are for grip.



The detail aslo shows the microdots as being above the 0.2" truncated dome height, making them taller than 0.2":



ADAS / CBC 11B shows these domes as having a flat top.


In your opinion, does this submittal meet code?

The truncated domes were never tested by BZ Bentzen for safety only tactibility. They are not safe there are no safety requirements published by the DOJ for these domes. The pads peel up and entrap the foot, the bricks shift about with edges raised up, the concrete ones have already caused an ambulatory woman to become disabled when she tripped fell forward onto the dome and it caused her brain injury, when the dome crushed her skull inward. The doc said it was like being hit on the head with a ball peen hammer. because they are unsafe and they are under foot and not cheap to maintain, I don't spec them at all. I go with the grooves in the ANSI. it was tested for safety under foot and it was safe.

I don’t think California gives me the option to go with grooves. In 11B-705, Directional texture is reserved for transit platforms.
I think I’m stuck with truncated domes no matter what. Do these comply?

My opinion would be that although it doesn't show these in the code, to my knowledge it never specifically states that you cannot have them.

Another grey/gray area of the code?

11B-705.3 Product approval. Only approved DSA-AC detectable warning products and directional surfaces shall be installed as provided in the California Code of Regulations (CCR), Title 24, Part 1, Chapter 5, Articles 2, 3 and 4. Refer to CCR Title 24, Part 12, Chapter 11B, Section 12-11B.205 for building and facility access specifications for product approval for detectable warning products and directional surfaces.

INDEPENDENT ENTITY
Sections 12-11A.205 and 12-11B.205. Evaluation by an independent entity to confirm the prescriptive and performance standard of detectable warning products or direction surfaces installed after January 1, 2001. An independent entity is a not-for-profit product safety testing and certification organization, dedicated to testing for public safety. An independent entity would operate for the testing, certification and quality assessment of products, systems and services.

Yes, the micro-dots "are for grip".
Without them, the pads are slippery when wet.

I agree they are important. My question: is the height of the microdots to be included when measuring the code required 0.2" height of the truncated domes?
If "yes", then almost none of the manufactured truncated dome fiberglass panels comply.

 

[Yankee Chronicler]

I would say "Yes."

Anyone measuring this?
