The Barn, Foundation part 3

With the inspection approved it was time for concrete.  After some measurements, I decided to pour 12" thick footers instead of the 10 inches that the plans called for. My reasoning behind that was that code calls for a 24" ground clearance, and a 10" footer would have required me to add an additional block, lifting the barn to almost 30" off the ground. I would be okay with this if we weren't using 2x12 as the subfloor, as this would have put our door 42" off the ground.

After putting a call in to a local concrete company, we were scheduled to pour.  Here's some wise advise about concrete that I'm glad I did not have to learn the hard way. DO NOT mix or pour concrete if the temperatures are bellow 34F. That day the low happened to be 34F, so I opted to pour after 10am to give the temp time to rise.

Here are the tools I used: 6'cu wheel barrow, standard shovel, float, and a hired back (the same friend who helped me dig the holes). 

If you do this your self, don't be cheap and skip the wheel barrow. The extra money spent on a GOOD one was well worth it. However, be careful, it gets heavy when it's half full. Why not just pour directly into the holes? You could do it for the outer holes, if you have the clearance, but I recommend asking the driver to take it slow, so you don't end up with too much in the hole. We could only do this with 1 hole, but I didn't want to risk knocking over a batter board, so we did it all the hard way. The end result was worth it.

We used an estimated 1.7 yards of concrete for the 12 footers.

After they set up for a day, I went back out to work on the the piers. This part is why I did not want to hit the batter boards. Setting the first pier too about 20 minutes from start to finish, without fill.

This step was pretty simple as long as the lines and rebar are in the right place. I just stacked 5 blocks with mortar in the joints. I think the hardest part is going to be filling the voids with block fill and setting the anchor bolts.

Day 2 of digging holes for our footers was a much more successful day! I was able to get 6 more holes dug before my auger, and I, ran out of fuel. Sure the holes weren't pretty as the first, but they were a lot quicker.

In case you were wondering, this is how I used the auger to help me dig the holes.

On day 3, I was able to hire a friend to help me dig the final 5 holes, and we were able to knock them out in about 2-3 hours. All 12 holes were complete! Next, was what I assumed was going to be the easy part, rebar.

That day, I made a trip to one of the "big box" hardware stores in search of rebar, 5/8" #5, to be exact. All I could find on the shelves was 1/2" #4, and that was not going to cut it. So calling the "orange" hardware store, I was not given a definitive answer about what I needed. But, the nice folks at the blue store informed me that Mobile Lumber should have what I needed. Now I don't normally indorse hardware stores like this, but not only did they have what I needed, it was about $0.50/ft whereas the orange store was $1/ft.  While ML had what I needed, it was only available in 20' runs, and that was not fitting on top of my SUV. Refusing to leave there without it, the guy managing the lumber yard kindly volunteered to bring it the short distance to my folks house, where I planned to cut the 20' down to 96 - 18" pieces and 24 - 5' pieces. Of course, I had to pick up an angle grinder and some cut-off wheels (insert sly laugh, as I just "hate" buying new tools).

What the plans called for was a square of 8 - 18" pieces and 2 long verticals with a "J" bend, like this-

To hold th squares off the ground, I used 3 short runs of rebar as legs, although, it would have been better with 4. I would like to note that working in a tight spot like this was not easy.

Thankfully, we passed our first inspection.

Today was an exciting day! We officially broke ground on The Barn!  

After doing the tedious work of lining everything up and setting steaks for all of our footings, I was able to officially put a shovel into the ground to start digging for the first footer.  After about 2 hours of switching between two shovels and a power auger, I had successfully made a 2'x2'x32" hole in the ground for the first of 12 footers.  And after consulting an experienced home builder I know, it was a pretty hole... Maybe too nice.

I will walk you through the process, if you want. If not, the pictures are below.

  After getting everything as square as I could, I checked level and determined that I need to dig 10" deeper on the high side, in order to reach 22" on the low end and still have everything level.  After marking out the 2'x2 hole, I started with the 8" power auger in all 4 corners and in the center to loosen the clay. That made it much easier to dig with a shovel once a good portion of dirt was removed and some was loose.  Then it was a repetitious process until I reached depth.  Once the proper depth was reached, I made sure the hole was still 24"x24" and leveled the bottom a little.
