need help with small shed build

[jones_2507]

hey guys need some input i have a well house that is 12x16 with a solid 1.5' concrete ceiling so im going to build a shed on top of it to store small items shovels fuel fertilizer etc... so i went to menards and built a kit my question is im doing stud walls and putting tin on the outside the kit comes with plywood to put on the walls as well do i need that any benefit to using plywood also... and can i just screw the tin to the studs or do i need to run some 1x6s lateral to screw to? never really build a barn thanks for any advise

If you plywood the walls just screw the tin right to that. If no plywood I would screw some purlins on outside of the studs. Purlins are horizontal 1x or 2x material to strengthen the wall and attach tin to that. Put a purlin every 2 foot or so vertically.

Ayuh,.... Generally speakin', No, ya can't screw the tin roofin' to the studs,.....

Studs run 16" or 24" centers,....
Tin is 3' wide,...
The seams won't match yer attachment points,....

Any benefit to using the plywood is it a better barrier to keep weather and insects out ?

Yes it's better for weather. Steel siding always has some gaps at the seam overlap, at J-channels, etc.

If I had my barn to do over I would have sheathed the entire building, put a home wrap on it, and then installed the steel.

Is there still a well in use inside the well house? I'm wondering about storing things like fuel or fertilizer on top of it - make sure there's no possible way for anything to leak downstairs.

1, bad idea to put anything petrochemical over your water supply.
2. 1 1/2 inch thick concrete is not that strong, I do not know how much steel was used in it but would not put much faith in it wo carry much load over that size an area.
3. Plywood would also increase your rack resistance.
4. What is your backup plan if/when your well is polluted?

Are you saying it's bad as far as the fuel or fertilizer leaking down to the well if the fuel is in a good container and I don't use liquid fertilizer is that what your saying ?

Your saying a foot and a half thick concrete isn't that strong ? And the actual size is 8x12 and the stairs going down make up the other .. what is rack resistance? And are you saying my well will get contaminated ? Sorry for all the questions I'm just wanting to make sure everything is ok before I go ahead with this if I have to I can still store the fuel in my garage just trying to utilize the empty space in top plus every time it rains the flat doors leak so I need something to cover it all

Your concretebis 1.5 ft? Have a photo of the slab? Thats serious thick concrete. That's part of the confusion of the one post, he thought it was 1.5 inches thick...

Next think rack strength or racking is the tendency of the building frame to bend or bow or wiggle around. The plywood will create angular support that will kewp everything solid and square. In my opinion ribbed tin siding will do the same thing. Its quite strong and stiffens the wood just like OSB. Also some triangular supports in your stick framing can help too.

Next purlins are the best way to do tin unless you do sheet the whole building. Tin really needs someplace to run a screw in every 12 inches or so (every rib) and its way to hard to get stub frames that perfect.

I also feel for what your doing a post building may be easier and cheaper... put 3 or 4 posts on each side and purlins wrapped around and hang your tin up.

Final thought...Im in the same boat as the other guys about being nervous with chemical storage right over a well. I donno if you're drinking from it or just water plants but still...

I would worry the effects of some crazy accident causing a gas can or fertilizer container getting knocked over, damaged and leaking into your water. Is it likely, probably not, worth the risk, also probably not...

Only you know the total situation and all risks and if thats worth it to you. As long as you know and understand then I say use your own judgement and go from there. Maybe your well is much more contained than a literal hole in the ground like what im familiar with, I sure dont know.

It does sound like a good place to put a building, pads already there. Good luck with it.

You are all right about the fuel and chemicals above it so I'll probably keep those things in my garage but I still want to build the shed over my well house you'll see in the pic the two pieces of metal is the hole to go down a ladder so I want to square the whole thing and build steps going down

Anymore ideas for what I could do like build a pole barn style over it instead of studs?

jones, if you have a couple of "Big Box stores" nearby, go to each and look at the sheds besides GOOGLE and steal ideas to help you with your project. I wouldn't worry about chemicals polluting your well because it should have a sealed well cap on it to prevent ground/rain water from getting into it. Some people are just "Internet Paranoid".

Go back to Menards and go to their book section.
They will have a collection of shed building books that will give different styles and reasons for the suggested construction.

Looking at your photo, is the ladder going down under the two metal pieces...and the rest of the well house is under the picnic table?

 

[lakeroadster]

Thinking about this a bit more... I'd be inclined to buy, or build, a free standing shed and set it there. That way if it ever needed to be moved... it could be.

Have you considered that?

Yes it is it's a pain to take salt down there my water softener is down there too

I have and also if I ever needed to do anything major to the pump but that's why I plan on not going overboard on building it so I could take it apart easy

I'm going to be pouring a concrete slab to square it up plan on doing 5" thick plus 4" of packed sand under it like I said before I'm not going to be putting anything heavy in it is that thick enough ?

2x4 forms at 3.5 inches thick should be plenty thick for storage building
