What about using the existing system return to supply the new area, if this happens to drop the return to low, then have a pipe from supply to the return to temper the return before the water returns to the boiler to insure system functions as originally designed. Do not know how to or what...

Question that the garage side of the partition would be warmer than the house. Condensation should form when the cold air hit a warm surface,, I would assume your garage would not be kept warmer than the house?

What you appear to be getting ready to place is called a grade beam and not a footing. I think your inspector may have indicated that it must be 42 inches deep and 12 inches wide. How do you plan on maintainng grade, looks to me you are heading for an outcome that most likely you will not be...

If you use limestone, make sure that you wet it down when compacting as well as when you get ready to place the slab. If you use a vapor barrier, the wetting before placement is not necessary. You want your water in the mix to be available for the cement to hydrate.

Maybe need a couple pieces of rigid insulation around that band offset. Both vertically and horizontal if possible. This maybe would make a better barrier than you have now.

What is the velocity of the water coming out of the pump, If over 4 to 6 fps, their are issues with corrosion erosion in copper pipe if the velocity is too high. I have seen this when the return lines in commercial domestic hot water system are reduced with the thought that usage will reduce...

There are "Z" purlins that hold the rigid insulation in place, flat portion against the block, 90 degree along edge of insulation board, with another flat to go over the edge of next sheet. These are used commercially available.

From my experience, make sure you check the connections. I went through a few tanks and did not do so. Found out mine was leaking when I used the welding machine. Also, shut off the gas when not in use. I went through a few tanks until I wised up, fairly expensive learning curve . The one I...

Size the pit to the size of the lift, then have the platform act as your support for both foot traffic as well as the occasional tire load. I have a motorcycle platform lift, when I mover I plan on this type of set up for it. May not met your needs, but this is my plan in the future.

You are in a cold climate, probably do not desire to cool the space in the summer. Unless you spend the money to put dry-vit or siding on the exterior you are limited to insulating on the interior of the building. There are Z purlins made that make the installation quick and not to pricey(use...

The material comes in a coil, you should be able to purchase at most lumber yards it is not cheap, but not too expensive either.

First of all is his proposal less than the others? I would not use anything less than the 4000 psi. If his quote is considerable less, then I would ask him to bid the 4000psi. In my area it is minimal savings for the reduction of 1 sack of cement per yard. I am an engineer and have been...

Reinforcement on the forms, looks like round steel ties to keep from spreading.

Depth should be 1/4 of the thickness of the slab.

I believe that Tim's response is dead on, you might look around the area you live for similar activity in sidewalks and driveways. Unfortunately, not aware of a fix. In my area, to comes with the territory.
