Between 705 & 1200 SQ/FT The Hobby Shop - Down in the Holler (24'x32')

Installed the electrical/CAT6 conduits. Purchased the Pella windows.

Acquired three estimates to have a 32’ X 24’ slick 4” slab poured at 4000psi (about 10 yards) The requirements of the estimates needed to include the following; check for final grade (I have a pile of 1/2” stone if any areas need leveling), pumper truck needed, fill the interior of the cinder blocks not already done (3 to 4 yards), All 3 estimates range between $6500 to $6900. WOW! Frankly, I wasn’t expecting that much.

I'd be all over that price for that much concrete. That works out to $9 a sqft. But I would go thicker for the floor, at least 5".

I played around with the DUCK browser AI program after your response and it agrees with you. $9 bucks a sqft is in the medium range. The estimates I received appear to be on point. How the times/costs have changed since my last build in 2013. I'm considering your recommendation of a 5" slab. It would be an additional 2 yards of cement. The benefits of 5" vs. 4" are appealing.

You couldn’t compare 2019 prices with today’s price. I cringe about how much i will spend on concrete compare to what it would have cost in 2019.

Done spreading stone. We are on the money. Slab pour scheduled for next Monday. That should give this last layer of stone some time to settle in. Getting closer to framing.

How much stone did it end up taking? What depth? Are you tamping it or did they do that for you? My garage will be 26x32, so I am watching with interest.

LOTS OF STONE! About 60 ton. There were 3 tri-axle dump truck loads each carrying 20 tons of 3/4”stone that dropped their loads on a level lot down the road from me. My concrete driveway would not support that much weight without damage. That stone was shuttled with a smaller dump truck driving across my lower driveway and up the front lawn to minimize any driveway damage. So far, so good. The back of my shop is 8 block courses high (64”) and the front is 3 blocks. The stone was inserted in stages over a course of 10 days. Each layer was watered with sprinkler or rain which helps the stone to settle. There is a positive drain on the back wall. The Mini-X did the compacting. It’s a strong base. We also brought in a load of 1/2“ stone for final grade if the cement guys need it.
