Insufficient detailing? 2

[AELLC]

I don't get it - (see attached)

This is high-end spec home- the floor is basically at 3 different levels because it is on a hillside - the floor slab is mostly California-style, uniform thickness post tension, and a little 4" conventional here and there.

Of course, the exterior grade varies constantly around the perimeter. So we have the foundation plan on 3 separate drawing sheets (this is only one of them), and 2 unkeyed details, both of them referring to the retaining-type schedule above.

The concrete sub - THE biggest company in the Phoenix area (and they have their own engineers, they routinely design similar projects all the time in-house, including pt slabs and basement walls)- they are saying this project is not detailed at all, and they have marked up the foundation plans with approximately 60 different locations, demanding that I "clarify" (that is the construction peoples' favorite word) every one of the 60.

Huhhhhhh. How to deal with these bozos diplomatically.

BTW, we also have a full sheet of standard post tension slab on grade details, also in these plans, which they have seen at least 200 times in the last 16 years.

@Mike,

They have a proper set of layers. I meant re-assigning layers. I don't know much about CAAD.

OOPS and a new lesson learned, but a good outcome.

I wrote a really diplomatic email to the CAD drafter, nothing nasty.

He forwarded it to the concrete sub - ooops

Now they shot an email back to me, and everything is all sorted out, now.

Why would you have the rebar on the soil face?

Just curious...

During construction of a retaining stem, there is no shoring. SO the finished condition is opposite the more critical construction backfilling condition.

I was looking at the retaining stem wall on the first drawing and didn't realise it may have been cantilevered... I detail it differently, though...

OK, illuminate me. I welcome any and all constructive criticism.
