Now it’s my turn for a workshop build thread

[URY914]

Sunday morning at 7:15 they get back on it with the trowel machine. It spins metal blades and basically polishes the slab to a smooth finish. It can't get into the corners so that has to be troweled by hand. More hard on your knees work.

[A930Rocket]

Looks good!

[URY914]

I wanted a curb so the walls will be up on the curb. This makes the bottom edge of the interior walls to be off the floor. Also easier to clean the corners and find that ball bearing after I drop it.

[URY914]

The slab will have control joints cut tomorrow. This is right at 600 s.f. The cut out in the curb is for the door.

That's all for now. Wall framing is next. Stay tuned.

Only if the Architect is a licensed PE and not many are. I tried to only used signed/sealed drawing from the Architect with building department. Told the plans reviewer it was a work shop addition and not a living space but no go. I needed s/s plans from a PE. $750 later I get the detailed structural drawings. All structural members are sized, details on walls, slab etc.

^^^ The wood is a temporary form. The footer/edge is poured first, then the slab. All in one pour. We call it a mono slab, but there are probably other names. After the concrete is firm enough, the forms are pulled to finish the inside edge/top/outside edge, fill in the honeycomb, etc.

One thing I noticed, was no anchor bolts installed. Will you drill and epoxy threaded rod in?

[Shaun @ Tru6]

Thanks, that's what it looked like, and seemed logical. Important to know for my own project this spring.

That's right. They are actually threaded rods that are epoxied in and connect to the top plate of the wall. Engineer calls for 3/8" which I thinks is pretty thin. I was lucky to find some 5/8" rods from a friend for free.

The outside forms were able to be removed late on Saturday after about 6 hours after pouring.

3/8”? That’s really small.

Years ago, we used 1/2”. Now it’s 5/8” every 4’. An LTT19 every 8’ and both sides of all doors and windows.

Make sure you get good embedment...9” or so. Drill the holes and use a bottle brush and compressed air to clean the holes out. 3” square washers.

I'll have straps, clips, brackets, rods, etc, etc. Simpson Strong-Tie owe the code writers big time.

Paul looking good so far I will be following your progress . Will you install AC ?

[flatbutt]

Cool, keen to see how you treat the roof wrt big wind.

[Zeke]

Nice, and I read where you said concrete "placed," which is the trade term. But it was still workable the next morning!!??

We had a lot of rain, high humidity and mild temps so yes they could still trowel it the next morning. If it was in August with the sun beating on it they would have had to stay an finish it same day.

It sure makes it easier when you don't have to worry about frost heaves.

Cool project. When we were looking for our house I told my wife if it did not have a three car garage it had to have the space to build a workshop. We found a place with a three car garage and a built in workspace. I still want to build a workshop, but it is never going to happen with a wife that is a master gardner, and keeps expanding the gardens.

Paul, looks good so far, thanks for starting your thread

I'm really going to enjoy following your build and to see how you do it on the other side of the pond

Thanks Captain. I've been watching your build and planning mine. My 2 x 4's are going to be a lot lighter than your stones and steel beams.

Last two weekends I been prepping the existing utility room walls for the tie-in of the new addition's walls. I've removed the vinyl soffit material and the 1/4" masonite which appears to be original to the house.
