Those with concrete/paving knowledge

From the looks of your first post, there will be concrete by Tuesday. Usually don't put the chairs under the rebar until right before they pour.

That much flatwork with the chance of rain they have on Tuesday morning, probably not going to happen.

I only do pool decks that are not under the stress that a parking lots gets. That being said I would shoot a sub if they tried to pour a deck without doing some serious prep work first. I remove all vegetation, treat the soil with lime, level it, lay down a substrate, use coated rebar, and then do the pour.

Why coated rebar?

Why coated rebar?

Protects the rebar from rusting/corroding inside the concrete.

Regular rebar is going to outlast you.

Why coated rebar?

Been on many job sites and have never seen coated rebar used. Regular rebar properly installed will outlast you, your children, their children, etc.

I use it when building pools and it is what my supplier stocks. Using premium materials and building it strong is also part of my sales pitch to prospective clients.

I pull up decks that are ten years old on a regular basis and frequently find nothing but dust where there used to be rebar.

The coating is just some kind of green paint. I see it being used when roads and bridges are being built and like I said, it is what my supplier stocks.

I am not trying to leave an impression that I am an expert on this subject. I do not do parking lots. What I do works around a pool so I assume that it will work in a parking lot.

Nope wrong. Nothing wrong with the rebar as is.

We build roads, bridge caps and columns with non coated rebar. Only bridges use coated rebar.

Negative. Rebar corrodes all the time, especially when the concrete becomes damaged. It lets moisture and other contaminants in to attack the rebar.

And roads never need to be repaired either, right? Not every project needs coated rebar, and I didn't say this did. The question was asked why coated rebar, so I answered it. Concrete is porous, and all sorts of contaminants will attack the rebar. You don't have to search long to find failures due to corroded rebar. Remember the walkway that collapsed at the Charlotte Motor Speedway years ago? Corroded rebar. I've worked on parking garage repairs in cities like Baltimore where rebar, conduit, and everything in sections of the concrete was corroded away. The rebar is of far greater importance to a bridge, that's why they're using it there. The added cost doesn't outweigh inexpensive repairs for standard roads, parking lots, etc.

It's an epoxy coating. Since you're dealing with pool decks and added factors like chlorine or salt and other chemicals, the coating is ideal. Obviously the concrete is going to get wet, and as the moisture penetrates the concrete it takes the contaminants with it.

So it looks like I'm a day late and a dollar short. I told the GM who grabbed the owner and went out and discussed it with the contractor. Contractor brought his engineer and the city inspector and all of them said it was OK. Contractor said he's pouring 4000 PSI concrete and that it will be fine. They're pouring concrete now, certainly to hide the shitty job.

Take pictures, document the whole thing.

What kind of warranty is the contractor providing?

Can't believe inspector passed that.

Either he was paid off or since it's a parking lot they don't give a shit.

Inspections on flatwork, typically aren't very thorough. They have a basic list of items that they look for. Each inspector typically has a couple of high points that they harp on. It is FAR from a best practices inspection, more of a yep that'll do, type deal. Not sure which municipality that was poured in, but they may not have adopted a newer building code. Though, I don't know how much the code has changed for flatwork inspections over the years. Juiceweezl could probably enlighten us more. Also, he is not the one to try and argue with over construction material and practices, he knows his shit, inside and out.
