New shop build, Doneish but continuing shenanigans

[truckdiagnostics]

Consider labeling your loops. Then down the road if you need to increase the flow in any one loop or notice cold spots it will be easier to make sense of it.

 

[rangerfredbob]

Yeah, I zip tied the loop ends together but I'm going to sketch out the areas to document better, I'm not going to be using the floor heat in the near future (probably at least a year out, there's much more important things on the list). I'm likely going to take a couple 2x4's and tie the in and out that far apart to give room for manifolds, right now they're just zip tied to a rusty piece of rebar I found...

I thought about paper, maybe I'll get a roll of butcher paper or something... but it might not be too hard to clean off the insulation backer.

 

[EddieWalker]

That looks really nice. Where will you be bringing your water from? Does that line go through the slab too?

 

[rangerfredbob]

Pump house is ~75' away, eventually I'll run a line from there to the bathroom area. The two conduit's by the manifold area are electrical and likely internet.

Before you pour concrete, I would put grey PVC conduit sweep elbows over each line where it comes up through the slab (and possibly add a 1' piece to extend them up). That way the concrete guys cant accidentally run the power trowel into them and make a mess.
If those are 1/2" lines, 3/4" conduit sweep elbows will slide right over them IIRC.

Here's a pic of the shop from the road, the building is only like 35' from the road, I scraped some goo from the soft area and put a yard or so of gravel over it, should be more stabile now.

Just a note the Dodge isn't mine, you might say my problems more relate to Ford's as you might notice a Ranger, an Explorer and a Mountaineer in that picture...

How many loops and how many feet per loop?

ANd save be from going back through the thread trying to find it again...how big is the shop?

Based on pics,I would have put the loops tighter together along the outside. Then progressively space further apart toward the middle. Instead of all evenly spaced.

Also, did you do insulation board under the slab?

 

[rangerfredbob]

I'm in the Northwest, so my winters are vastly different than the central and lake effect area... if it's below 30F for a couple days that's generally a cold winter , about 10 years ago it got down to 6F for a day but that's rare. That said, I'm not going for perfect... I'll have a wood stove at some point for the majority of heating.

The shop is 36'x48', there's 5 loops 300-320' long, no foam board

 

[truckdiagnostics]

not like the above that was done 20 years ago on my first stab at this.

More like the above the plastic chase comes from menards? it is curved at the bottom.
Apologies on the pic orientation
That is for a 20 by 24 room in the back of the barn. I am going to heat it with a 40 gal hot water heater. Some piping and a pump and away we go. been sitting like that for over 2 years. Thing is I have the parts too. So, I hear yea.
i pressurized it and watched the air PSI before and after the pour, hence the manifold.
thing is if you know they nicked it you can always put air to it when the concrete is wet and you should see it bubble up through the concrete and can fix it. never had to do. Not going to be so easy latter. Do able, but more difficult. You put hot water in the floor and you can find it with IR camera. This I have had to do, because somebody drilled where they where not supposed too.
Interesting tid-bit.
In the new office buildings/factories they are installing in floor just around the out side perimeter of the building. that is in addition to the forced air.

Ok, progress, took half a day off work today to just make sure I could get ready this weekend, got a text message from the concrete guy today that we're going to try to pour next week!

I got my receivers welded together today, the rebar is at the same height as the mesh on the floor, I tied them on today. I also cut up some 6" pieces of 3" ABS to make plugs for the floor anchor's/chain pots, you should be able to see almost everything in the two layout pictures... gotta figure out how to weigh down the tubes, probably just fill with gravel, that'd be easy to shop vac out... I don't have enough tire weights... They're wired to the rebar but I don't think that's enough.

Double and triple check all your measurements. It's always amazing how things are not where they are supposed to be after the concrete is poured and you cannot see what's under it.

Yep, know someone who has a barn that is 40x60x40x61.
Posts are all on piers and somehow they got off by a foot when putting one side in.

Have someone else check from a print? My house foundation is a 1/2" off because I didn't account for the 1/2 sheeting and I double checked. I compensated for it, but I know it is wrong.

 

[rangerfredbob]

I had the drafter at work print me up a grid that's 36x48 on 11x17 paper unfortunately it's only about 8.5x11... but it has the right amount of squares so I'll sketch it up this weekend, then make a couple copies and scan it into the computer for good measure... Oh yeah, for those keeping track, I didn't use the previous PEX layout, when I drew it again since the trial expired at home it went a different way that I liked more... but it was a pain to modify things how I wanted in loop CAD so I just winged it once I got to the office end, by that point I had a good idea how the process worked...

I hate to admit it but, I could do that. For whatever reason, getting stuff square is hard for me.

I even own a tape measure that, to my knowledge, works.

[rangerfredbob]

The corners of this thing are square, at least at the bottom and pretty close at the top, I've taken WAY too much time measuring things that don't matter as much as I expect...

Sketching the thing out on the graph paper should help for documentation, and I charged up the digital camera so I'll climb up a ladder and get pictures of everything from hopefully every angle, already made a folder in my computer for "home and shop stuff" for future reference. after I get further along I'll back it up on my portable hard drive...

I have enough painters tape around I'll probably mark the rebar at the skirt board then run a ring of painters tape along the top of the skirt boards...

 

[rangerfredbob]

Ok, things are getting close, just heard concrete will start Wednesday around 10:30 AM!

 

[EddieWalker]

Are you going to be there when they pour? Remember, if they can get away with adding extra water, they will!!!!

 

[rangerfredbob]

Yes, I'm home, about 3 hours to go!

He said they pour on the thick side, I'll be there to pester and ask stupid questions .

This should be one giant leap toward me getting random cool projects done, I have so many ideas...

I pestered the electrician the other day too, so hopefully get that moving along soon too.

 

[rangerfredbob]

Went pretty good yesterday, the first truck was almost 45 minutes early. The only real hiccup was my grade was off a little here and there for my receivers and I made them 6" tall, some sit a bit proud so they tapered them out... will likely be a bit annoying but if I don't like it I'll just cut the steel short and grind it flat...

Might do pictures tomorrow, tomorrow night or Saturday I should be doing the saw cuts.
