Partition construction for Type I & II construction

[mschirmer]

I ran into an issue where i had a low height wall on my Partition Type page and was told it didnt comply with code. This is basically our standard construction section we've had for years. The comment back to us was the following:

1. Sheet # A1.01 – Partition type H2 - Types I and II construction are those types of construction in which the building elements listed in Table 601 are of noncombustible materials, except as permitted in Section 603 and elsewhere in this code. Please provide the exception number for the MDF and wood blocking. If MDF is one of the exceptions please indicate that it is “fire-retardant- treated wood”

My question is whether low height partitions fall under this statement made by the city. the only wood is the MDF blocking supporting plastic laminated MDF top.

Got a detail? All partitions fall under it, but the is some wiggle room in 601 or 602....

I wasnt sure how to load an detail, so that was the best i could do.

So the MDF is just blocking? It's fine....I could get 11 or 14 on that one I believe....

11. Partitions dividing portions of stores, offices or similar
places occupied by one tenant only and that do not
establish a corridor serving an occupant load of 30 or
more shall be permitted to be constructed of fireretardant-
treated wood, 1-hour fire-resistance-rated
construction or of wood panels or similar light construction
up to 6 feet (1829 mm) in height.

14. Blocking such as for handrails, millwork, cabinets
and window and door frames.

Maybe move the detail from the partition details to the millwork details, since it appears to have a countertop.

Careful, if it has electrical in it that is a potential source of ignition?
Is building a multistory?

I don't care and neither does the IBC.....

I wouldn't make that comment, one of the best details for a low wall I have ever seen. Do what he asks and provide the exception. #14 seems like a no brainer.

Yes, it is a multistory commercial building.
