Well years in the making I finally pulled the trigger on adding to my garage. I basically started the work last May. Took a year to get a variance and install a retaining wall along the west side of my property. Currently have a 2 car garage with a 13'x17 ' workshop on the back side. Moving forward I will be adding a 12' x50' long wall with a bump out on the west side of the garage the back will be blown out to 24' x 24' addition. Basically will be an L shaped addition. Walls will be 13' high so I can get an RV inside and a Lift that I have in my shop now. I will be doing away with a covered porch and adding a small family room off the kitchen. The 2nd floor of the garage will have 4 dormers and will be unfinished for the time being. Heat in the family room and the garage addition will be radiant. Currently have electric solar on my house that I will also be adding another couple thousand watts to along with a solar hot water heater. Will be posting pics in the near future.

More of the wall going in. Had to do it in sections. There is 18" of stone below the first course of block. The top block only has about 4" of concrete exposed on the top and then drops down 6". I wanted this look so that I have more green area between the house and the wall. some of the blocks are a little off but I tweak them as I go along to get them straight.

Digging the footing was a lot harder than I thought. I only have an 8000 pound machine and I was hitting a lot of ledge and stone. It was pretty depressing and I was ready to just cover everything up and not move forward. But a good friend of mine who is doing the concrete for me talked me into just getting it done.

Now that's a boulder! Whew that looks rough, are you going to jackhammer through it? Or try to break the whole thing up and remove it?
No that's not a boulder the picture has a boulder. In New England i once had a site contractor tell me the whole area is one big rock with a little bit of dust on it.
And to answer your question ended up pinning the rock. will load a few pictures later on.

Looks like it will be a nice garage. So, do you have a 1969 Grand Prix that will be going in there?

Found even more ledge and a large stump in the middle of the footing. This was buried 2' below grade. Could not pull the stump out so I made a ramp and had a stump grinder come in and made it disappear real quick. Best $150 I spent.
Attachments
Dug all the trenches and exposed all the ledge. There was a lot. Called a friend to see if he could bring a machine up with a hammer and break it out. Once he looked at it he just said to meet with the inspector and see if I could get away with just pinning the ledge. I had my doubts if that would work but he was pretty cool with just pinning it. He said that you are not going to get a stronger footing. So it was just drill and pin the ledge.

Walls formed up and almost ready for concrete. Stops need to be installed along with a few brick shelves. Concrete is a great construction material to work with.

All walls poured, straight and level. No blowouts and no pump needed. Brick shelf installed all on the east and north wall for a stone veneer to be done at a later date. Inside of the garage I did install a brick shelf where I have the wall bumped out for storage. This was just to gain an additional 8" of floor space.
Attachments
Forms removed from the wall. I scored a good deal on some used 3" and 4" Owens formula 250. I installed the 4" along back north and east wall. I installed the 3" on the inside. On both the inside and outside the insulation is sitting on the footing. I did include a picture of how I install electrical conduits when you use a Rapid style form. I use a 3/4" rigid 90 and then stub up with PVC to above the finish concrete height. Duct tape each end and secure the conduit inside the forms with wire to the form ties.

Few pictures of the existing garage foundation that is marked out for saw cutting & removal. I am also install a water management system to collect all rain water runoff from the roof. Will have 2-500 gallon tanks along the garage side with the capability to pump it to a 1500 gallon tank in the backyard. This will be used for lawn watering.

Walls and piers were saw cut. I was going to do this work myself but decided to farm it out. I installed temp walls on the back of the garage wall and supported one beam on the side wall to lift all the weight off the concrete walls. I had to leave for a few hours and when I got back all the work was done. Fast clean and efficient. Only got one picture of the track saw doing the cutting.

Well they always say measure twice and cut once. That works as long as the measurement is correct. After measuring the newly cut pier openings something did not look right. Come to find out I was off by 24" in one direction. Unsure of where it went wrong but had to make the fix. I did have an existing saw cut in the floor that was offset by 23". Just took my old Milwaukee skill saw and put a diamond blade on it to cut down a couple of inches to give me a clean line. After it was just drill a series of 6" holes with my Hilti core drill and then break it all out. It only takes about 2 minutes to drill each hole. Drill one anchor and keep pivoting off of that point. After completing the work it looked as if it was done at the same time as all the other cutting with the exception of the nice radius on the corners.

Removing the back concrete wall of the existing garage. Wedges can be seen that are supporting the wall after it was cut. I installed a temporary wall behind the one that is being remove. The area behind the wall is my old workshop. You can see the insulation under the slab. I did install radiant heat in this area but never used it. I plan on installing a sump pump in the garage so I did remove one end of the wall once it was pulled over. The wall section removed was 17' long by 36" high. Makes for a good solid base.

Don't know how I missed this. Any updates?
The new family room is being built over an existing concrete porch. Laid down 10mil poly followed by 1/2" Dow Tuff-R insulation over the whole area. 2x8 PT lumber was used for the floor framing. This was followed by 5" of foam insulation cut to fit between the floor joist. I then installed 1/2" pipe between the floor joist.

Have not posted for a little while have a ton of things going on. Received a nice big load of framing lumber to get things moving along. Lumber company did a great job laying the material out so you don't need to pick through everything. Also the radiant heat pressure is holding up great so looks like no troubles with that end.
