Storage Lockers Facilty/Warehouse - Design Criteria
Storage Lockers Facilty/Warehouse - Design Criteria
(OP)
Need some input:
We have a warehouse facility providing customers with storage lockers (8' x 10' x 8'H). Size of locker area...+- 85,000 sq.ft.
My concern is that I can't apply CH.13 Misc. storage (NFPA 13) as we are limited to an area of 4000 sq.ft. max. So I have to move on to Ch.14. If folks decide to come and store couches, or plastic bins, books, etc., would I be able to get away with classifying this storage of Class I-IV? or do I have to consider Grp.A plastics stored at < 8'H. This would mean 0.40 over 2000 (with zone reduction). The existing system is pipe schedule with a capacity of 0.25 over 2000 sq.ft.. Hopefully someone can give me some feedback soon. Client expects a quote in the next few days...

And I am going to take the area reduction.
If I had to make the determination I would probably go with Ordinary Hazard Group 2 as well because height is limited to 8 feet and to the bottom of the purlins I only have 12 feet off the floor.
I will be watching this thread.

These things are always crazy. We work closely with the EOR and owner to clarify what they are and are not designed to protect. I honestly hate these projects and turn most of them away because of these issues.

RE: Storage Lockers Facilty/Warehouse - Design Criteria
If it were totally my call I would opt for the Group A plastics just to play on the safe side but in this case that call has already been made and I have learned over the years if a professional engineer calls it you can have a discussion but in the end you give it to them their way with plenty of written material to back you up.
The way these are built the highest any storage can be is 8' with the underside of the steel at about 11'.
Partition walls between the units are 8' high with chain link fence material from the top of the solid metal partition to the underside of the steel.

I will agree there is a large amount of uncertainty with what could be stored within these units. It seems every situation couldn't be accounted for.
Typically we walk away from these because the owner's engineer has classified it as light hazard or something zany like that.
