concrete garage floor help
I recently bought a home that has an addition on the garage that I would like to put a concrete floor in. The floor is currently dirt. I read on a posting on here that you should not pour the concrete around wooden posts. It is not a very big addition maybe 7x15 but the wood posts would have to be filled around them. Can anyone help me out with how to put in this floor so it is done right? Thanks

What loads are the columns presently supporting? Are they sitting on concrete footings? You could consider replacing them with tubular steel columns, or eliminate them altogether if possible by modifying the overhead loading structure. If you want to stay on a tight budget, there's always the option of blocking around them with an inch of dense Styrofoam, should they rot and have to be pulled/replaced in the future.

They support the roof but go into the ground. How far I don't know. Its basically a roof with wood posts then they ran 2x4's horizontally then put up osb and siding to match the house. I am not sure how to put them on here but would pictures help?

yes the 2x4's are horizontal for the osb. it looks like it started as a carport idea just a roof and the 4x4 posts. the 2x4's, osb, and siding were added later. thanks for the picture help marksr. i will add some in a couple hrs when the storm dies down a little here.

Is there siding on the other side of the OSB? I'd be inclined to support the roof, tear out the walls, pour the concrete and then erect new walls on the concrete above the ground. Anytime wood has direct contact with the ground you run the risk of termites and rot.

Yes the walls have been sided to match the house. How would i support the roof for the concrete to be poured? I was afraid of that option but it seems to be the best way to just get it done right and to make it last. I appreciate any help from everyone.

So I assume the siding goes all the way down to the ground 
You'd build a temporary wall to support the roof. I wondering if it might be better to pour a slab inside of the room not touching the walls and then after you remove the form boards, fill those strips in with gravel. Ideally you'd remove the walls and erect new walls on top of the concrete to get the siding up off of the ground .... might be a bigger job than you want to tackle right now. Later on when the siding starts to fail you could temporarily support the roof off of the concrete, tear out the walls and then pour a footer, maybe a short stem wall and erect a new wall that will last a long time.
