Hello, I would like to build a shop / well plumbing building. I bought a set of plans
that will work for what I need. I will need to build this on a slab with a brick exterior (for subdiv requirements), which means that I need an additional ledge on the slab. I'm calling concrete contractors to get estimates. Some of them are telling me that I need to have my plans redrawn by an engineer for them to give me an estimate. I'm going to build this myself, except for plumbing, electrical and the slab. My question is; can I use the plans that I have for getting permits or will I need to have them redrawn? Or can I redraw them myself using some home design software? Are these contractors sending me on a snipe hunt? Thanks!
BTW, this in Hays County, Texas
