Homeowner With A Question Questions on slab for detached garage
Hey all, loaded and long winded question here.
I’m looking to have a slab poured for a detached garage. Due to my city requirements I had to have architects draw up plans for a wood framed building as they wouldn’t allow a metal building. The building will be 18’x20’
Architects came back with footers at 18”x16” 4” thick for remaining slab, 3 #5 rebar in footers, two on the bottom, one in the outer edge. What’s kind of odd from what I’ve been told by contractors is they called for 3lb/ cubic yd of fiber mesh. I’m being told this is way more than any commercial building would be, and this wouldn’t allow for a flat finish as the fibers would be sticking out everywhere. Does this seem excessive?
I’ve already pulled permits for the job and have everything ready to go but just need to narrow down pricing.
As for pricing, I have a couple coming in at $6700 for scraping land of grass that was previously cleared, digging footers, all prep work, and poring and finishing slab. These are licensed and insured guys.
However I’ve gotten quotes from guys who aren’t licensed who say they can do it for $3800. That’s all prep work and clearing. Plus form and finish. I would just need to buy rebar. Is there that much of a difference between the two that would make for almost a $3000 difference.
Aside from concrete being concrete. Is there any reason why I shouldn’t go with the lower priced quote? I’m sure the differences would be soil compaction and such from the bigger guys. But the $3000 will almost cover the materials to finish the garage.

Dropped a cap that fits perfectly inside the drain pipe. I'm afraid I'm going to push it further down if I try to remove it. What should I do???
