Originally I had thought about running some conduit in the floor for electrical but decided to keep it all above..

If I can figured it out.. I am going to put receiver tubes in the floor though and hook up a vacuum to these so they can be used for fume extraction..

I have a wood chip collector that I will hook up to it.

Interesting that the insulation system is also a "fall arrestor." Is this to protect the roofers while installing the sheeting?

Thanks. On many buildings the workers have to be tied in.. So, this system allows for them to walk freely on the framing without being tied in. I was told it is an OSHA requirement on certain buildings.

It is a crazy installation.. Though it does look nice but really not much of it makes sense.. In the instructions it said to run the side wall bands under the tension bands except ever 5th tension band.. It would have looked nicer going over every band. The side bands can't get tensioned nearly as much so sag some.

Thanks. it certainly felt that way on many days. Until it is completely finished it will still offer some angst.

Dave, I can relate to gimply.. So it might still be a good experience. thanks

No dirt. Years back I had dirt in the shop and while I like the action of it and the ability to move stuff around it was a constant upkeep and the dirt would end up everywhere.

Because it being a school Cement will have to be the standard.

I guess it's because of taking the easy way out. I honestly don't know how to make it less work.

I imagine setting up a cement floor everywhere else and doing a wood butt end floor would be a great way to go.

you have me thinking now.

What is the dangers as for stability in the concrete with only having 2/3rd the floor vs full?

I would have overhead fume extraction. I don't think in-ground is allowed anymore--you should check your code. In-grounds I've seen over the years (auto shops for exhaust) were always full of crap and didn't work well, IMO. Since you're not doing E-conduit in the floor may as well go for smooth with no protrusions.

The school is coming out great! I am excited for you! Will there be an inside classroom/climate-controlled area?

Picking at nits, it's not cement, it is concrete.

I would think that a compacted gravel floor using 3/4 minus crushed rock and stone dust would be the cat's meow but you have a point that your structure will be used for teaching.

A foundry casting floor would generally be covered in sand where the melting and pouring are taking place. I assume you don't really have the need to protect the concrete from molten material. How much spalling of concrete have you seen in your travels to other shops?

At our shop, any torch or air arc work near the floor gets a steel plate to stop direct hits. There’s a couple places it was missed and one can easily tell.

I love the idea of overhead.. But it would be more costly and complicated.. the infloor system is pretty cheap and easy to install overall.

If the fume extraction aspect does not work.. It will be turned into a cable feeder conduit.

But, with this said.. I think it will work very well. We will just have to see.

the whole shop will be climate controlled. The R38 ceiling and R27 walls will help with that. I initially won't be doing a cooling unit..

I have to see how it works out and even if the shop can start to generate funds to support itself first before anymore investments other than basic, lights, heat..

Thanks

If a casting area is put in it will have the floor lined with bricks in the pour area. Something safe.. Nearly all the foundries I have been into have cement floors with old casting sand on top.. But dig down a few inches and there is concrete.. I know its concrete but just like to tweak the people when I call it cement.

With this said.. What is the difference since I don't remember. ???? I supposed I could not be lazy and do a search.

I'm hoping this shop won't turn simply into a fabrication shop so ideally there won't be much work of cutting done on the floor with a torch..

But, if that is the case and it happens often enough it will be easy enough to retro a plate to fit the welding ground bars.

Today the main guy Mark came back and put in the crack grooves.

I also spent the time removing all the covers and opening up the grounding bars/i beams.

So, for future reference..

the threads on the fume extraction pipe.. Put grease on the threads and put the duck tape on.

On the gozintas.. Ideally install them and have the leveled as you put the fill in for compaction.


I had to install them 1 at a time and then raise them to height for floor thickness not being able to add more under them. This unpacked the aggregate so had 1 that twisted and 1 than is no longer plumb.

If done again. .I would weld them onto a common pipe and run the pipe full length..

Looking good. Always nice to have a new floor. Getting excited!

I could be wrong, but the difference between cement and concrete is cement is the binding agent that holds the sand and rocks together in concrete. So you can have cement without concrete, but you can not have concrete without cement.

If you just used cement for the floor, it would not have much strength.
