Sounds more or less how I did my pad, except I broke it up into 2 pours. I did taper to 7" around the area the lift is going. I kinda wish I did in floor heat, the shop I worked at had it, and I loved working on it, but I just couldn't commit to where it needed ran and not be in the way for anchoring the loft, lift, and palette rack to the floor.Will do . It won’t happen till summer at least . Don’t like doing concrete on frozen ground it always settles and my town loves to drag out permits .
Going with a monolithic slab 5-6 inches with 12 inch edge.plan is to have at least one two post lift and possibly a four post too. Needs to be insulated since I’m doing radiant heating .
Friend who dug the last part of the well line trench built a 30x60 with radiant floor heating about 5 years ago . I’ve worked in the garage with him and it’s toasty warm and he said it’s very easy on heating cost . Only thing he would change is to use a domestic hot water heater instead of an actual boiler for the hot water heater.
My brother in law and I will be doing the electrical, he was a union electrician in NYC .
Always nice to have an electrician relative/ friend. One of my work buddies is an electrician. He's been doing most the wiring in my shop/ did up the plans for it. I've just stuck with the basic stuff and pulled wire/ done the rough in, then get him over for the wiring.
