After some rain delays...stem walls are up!
This corner has some honeycombing despite all the vibrating they did during the pour. The lower ones will get filled in by the slab but the upper left part is a bit ugly.
This piece of rebar was too close to the corner and so it didn't get filled. It will get patched before waterproofing to prevent rust from spreading. I'm pretty sure it's just a corner marker they forgot to cut off, so it's not even connected to the rebar structure.
They say you get what you pay for, and I am sure not paying much 
Following along! Garage builds are exciting. I've been planning a 20'x30' in the back of my mind for my house, but it's a long way out.
Glad to see it's progressing.
They smoothed it out aesthetically on the inside and patched that rough outside corner. Waterproofing ended up just above ground line. Drain pipe and gravel next.
Yes that corner will be stupid to frame. GC is only my part-time job!

Just for the heck of it, look into this before you backfill the outside:

I'm curious if you are recommending this on top of the waterproofing he just did, or if you missed that post.
In reply to AWSX1686 (Forum Supporter) :
That tar looks below grade to me. It needs more than the tar. Even if there is some kind of water-proofer brushed on, I'd still use the Bituthene. It's the E36 M3.
It's tarred up to grade, just wasn't finished in that picture. Might throw some sheet stuff in there too if I find the time. Not too worried about soggy ground here since it's almost the top of a hill, and there will be a drain pipe and gravel in there too.

Nice progress! Congrats on the pending extra space. We all know it will disappear quickly.
What's the scoop on the coupe?
Edit: to be clear, not the Camry but what I assume to be a 5 window 32 Ford?

34 Chevy and it's challenge eligible...

Looking forward to the build thread for that one although I imagine the garage will need built first so we're gonna need you to hurry up.
Slab is down! Was pretty nervous but luckily it was a different crew than who did the walls.
They scooped out the dirt inside the footing and backfilled with about 4" of gravel.
I had them dig out some extra deep squares that will cover any 2-post lift on the market.
Wire mesh over waterproofing. Plus the epoxied sill anchors into the footing. There was another inspection at this stage before the slab pour and it all looked good.
It took every bit of 9 yards of concrete, which is an average depth over 5" if you calculate it over the area. They used 4000 PSI with a calcium additive since it will dip below freezing tomorrow night. Yes they pulled the wire mesh up.
Power troweling will happen either late tonight or early tomorrow morning due to the slow curing on this 50 degree day. Tonight's low is only 44, but tomorrow night and Friday night's low will dip in the 20's, then back up to 50's and 60's this weekend. Blankets until then.
In the meantime they are demolishing the driveway and sidewalk. The sad blue 4x4's are banished to the street for a while.
They're power troweling at night by the light of truck headlights and work lights. About every hour or so, checking the concrete in between. I'm glad the slab was subbed out because these guys are much better. Should be nice and smooth tomorrow.
How did it turn out?
New shops/garages are fun.
In reply to low_n_slow :
Slab is very, very smooth! Pretty happy with it so far. I'll take pictures once the blankets come off tomorrow due to these cold nights.
I do not plan to epoxy or polish it or anything like that. Probably just a sealer or some kind. Recommendations? I don't mind some staining over time since it will be abused by a GRM'er doing GRM things, but if there is sealing product to make it easier to clean up I'm interested.
I know you said you didnt want to do epoxy, BUT, I would highly recommend the product I used in my garage. V-Seal Industracoat, my garage is 24x32 (so ~750sqft inside), I bought a 1200sqft kit and it was ~$550 shipped. So small investment for something that is really resilient, definetly can spray brake clean on it and it laughs!
Just found out why my driveway had such a steep, short slope to the street. It's a big ol' piece of granite! Spans the width of the driveway and the original concrete was sitting right on top for 50 years. The skid-steer jackhammer just won't break it, and it's way too big to dig up. Might have to call in a bigger machine ($$$), or live with bottoming out on this hump forever. The Rice Rod scraped it very often... hmm.

Or blasting, you can never go wrong with a good blast or three. In residential areas it's drill away load the holes, cover with blast mats, the count down horn then whump and the all clear.
Seems like my county needs a permit for blasting. One blasting company says they can hydraulic fracture it, which doesn't need a permit. Pricey though. Still looking for a bigger jackhammer first.
Wet saw chunks out and sell them for counter tops. Keep going until you have the room you need.
It's a feature, not a bug! Incorporate it into the driveway, and pour around it. Or go around it.
My experience with big underground rocks is to leave them alone. I watched 4 truckloads of 3-4" rock disappear into a resulting void. And it's still sinking years later.
