Skid foundation shed

[NitroNic]

Hi,

I have plans to build a shed in the back yard. A previous owner had a 10' x 14' concrete slab poured. I'm not exactly sure how thick the slab is but looks to be at least 4". Not sure if it's reinforced or not. I suspect it had a shed sitting on it, or maybe a boat.

I have plans to use this slab to support a shed. I was thinking of using some 6x6 treated lumber as skids, and placed them on this slab and then frame the floor of the shed on the skids. I assume I'd need 3 or maybe 4 of these, running the long dimension of the building, not sure how they should be spaced either.

I'll probably have 1001 questions along the way, but I'm wondering if it's a bad idea to use skids longer than my slab (16' instead of 14), and frame the floor at 12' x 16' to keep measurements in multiples of 4 feet and gain some square footage.

Is having the floor frame extending 1' past each side likely to be an acceptable engineering practice or should I keep the floor dimensions equal to or less than my slab? Or is more info needed?

Note: I live in Oklahoma, it sometimes gets windy here.

Thanks!

Nic

a foot hangover on each end and each side, i dont see a problem with that. if a 6x6 won't hold it nothing will. i have a 8x16 with a 2x4 floor frame that has a 4'' pipe frame under it that only 4' wide, so a 2' hangover on the sides. that was built 18 years ago and has been mover 3 times and it's still standing

I agree with Paullie!!

If you are getting permits they will most likely require you to anchor it to the slab. You can do anchors in the concrete and bolt through the skids or get one of the cable anchor systems if they allow that in your area. I know in Missouri they worry about the high winds/tornado picking your shed up and throwing it on your neighbors house. I get their point but if it picks my shed up with all the **** I have in it the neighbors house is probably gone already so it's a moot point.

I'll have to go back to the building services office and ask. They told me a non-perm structure like a shed doesn't require a permit if it's under 200 sq ft. I did plan on digging a trench and running water supply, electrical, and possibly gas supply line to this building as well, which they said I would need permits for, but I expected that.

I will say that my dad has a 16x20 I believe, on skids, and also lives here in OK. It was a prefabricated building moved to his yard but the skids rest on concrete blocks and through 10 or 15 tornado seasons, I haven't seen it budge. It's a barn style, and I had planned to do something more gable style. Make it look like a small house.


The idea is that this will be my beer brewing building since right now it takes place in the garage, driveway, and kitchen.

I'll see if I can draw something up in Sketchup and post a picture on here.
