Pushing the budget..

[truckdiagnostics]

Well, go big or go home. Just finished a 30 x 70 with 16 foot walls. Gets me a 14' door so i can get truck in, also will get me mezzanine with enough height to walk under. You can't add height and IMO 14 with a 12' door isn't going to allow everything to fit and there are some awful tall RVs out there. If you want to get an RV in figure 14' door, you can do it with truss design and door location and still have the 14' sides. If you don't need the height for RV go with rafters in the area for the lift and keep your height down and save the money. If money is tight now make it smaller with plans to add on. I have gavel floor and we are doing the concrete in bite size chunks. Might not be an options depending on how you are building yours. You can add on but you can't, not easily anyway, go up. Its never going to be big enough. The above building is our third and each one is bigger than the last and the above is full already. So, build for what you need now and can pay for with plans to add on. The adding on plans is important, first building didn't put grade high enough, so getting the drainage around the others was ruff.

Forget the extra cement and height and make the build foot print bigger...maybe 40x60 or bigger...whatever you can do with the $3500.

Within a short time, you'll be wishing you had.

He's hitting you pretty heavy on concrete. Its just over 4-1/2 yards at $110 a yard. My concrete guy doesn't charge me extra labor for additional thickness. Metal is $2/ft. So that's $640 on just metal. Biggest expense on that will probably be longer posts. 20' posts are $80. 16' are $45.
What about a vaulted truss if that is what you are using.

If the fiber concrete is in stead of rebar from my experience that would be a poor choice. I would have a rebar grid and up the strength of the concrete and stick with a 4" floor.

Need some input once again from you seasoned guys here- I'm about to amend a pole barn contract, and the cost to increase the 4in fiber concrete floor to 5in is $1556. To increase the 12ft wall height to 14ft is roughly $2K. This is for a 30x50, and now is the time to make up my mind:laughing: I would like the future option of both a 2 post lift, and a mezzanine, but a $3,500 savings by staying at 4in crete and 12ft wall height is enticing as well. Thoughts??

Can you raise part of the roof?

I wouldn't bother with the 5" floor for the uses you have mentioned. But wall height might come in handy. Need to know more about the roof construction -- standard trusses with full bottom chord?

For four thick thick slab, the rebar is rarely in the right position to strengthen the slab. When you install the rebar with clearance from the soil, the reinforcing is in the compressive stress zone of the concrete. To strengthen the slab it should be in the tensile stress zone.

Four inch is a thin slab for equipment storage unless you have a similar amount of gravel also.

Do just one bay for the future tracked unit and go 6" with 1/2" rebar on 12" centers. Leave rebar and mesh out of the rest if using fiber; doesn't add anything except cost. Do not let them walk on the rebar and make sure it is on chairs. 4" (not a 3 1/2 form) is fine for any other load you can put on it. Do not forget the control joints on no more than 14' centers. I would take the overall dimensions and divide equally both ways. Saw them the next day and you have wasted more money.

I just poured 238 sq ft of addition to my little shop. The crete was over $100 yard and the fiber was $9 yard. The finer cost nothing extra in labor and you could do that instead of the extra inch of crete. The extra space above your head will be easier to pay for without the extra $$$$ for the crete. :2cents: Ed

Let me give some feedback and clarification- this pole barn uses one type of truss, and the true height from the crete floor to the bottom of the truss is their advertised wall height. So, it would indeed be 12ft or 14ft clear height. The footprint can't really get any larger, so that is why I'm wanting to go higher. I think a likely route will be that I will do the 14ft increase now, and just not do any concrete until after the barn is finished.

2 reasons: One is that the ground hasn't been cleared due to weather in SC. I think it would be wise to let the ground settle for a solid month before the concrete is applied. The second reason, is that I'll cut the middle man out (why the crete is so $$?), and give me a chance to know what thickness I need. But it does sound like 5in would give me a 'warm and fuzzy' that I should be able to place anything on the floor in the future.

Anyone disagree to just hold off on the crete until after the build, and deal directly with the crete company? The other issue is that prices on crete are supposed to increase in the new year?
