Concrete Rebar Shop Drawings 1

[MacGruber22]

Does any body else have trouble getting detailers to provide rebar clear covers, etc. on their placement drawings? If so, does anyone have a "scary" CA note that they find useful to place on the shop dwg review pdfs? This is one of the most annoying peeves of mine. Devil's advocate: Maybe it shouldn't be?

Showing the cover and basic dimentions of the concrete could be useful to the fabricator as a double check on the bar lengths.

I agree - it also useful for the detailer.

hokie66, that is interesting - and somewhat of a reasonable approach.

Thanks, everyone.

I have found some rebar detailers who DO indicate the cover requirements - but it's not consistent and may vary from detailer to detailer.

IMHO rebar drawings are intended to serve 3 distinct and separate purposes:

#1 - Demonstrate the detailer's interpretation of the contract drawings with respect to bar sizes, arrangement, splices, etc.​

#2 - Determine the bar quantities, dimensions and bend details for their fabrication.​

#3 - Provide the means by which the installer can identify which bar goes where.​

The engineer of record is obligated to confirm #1 in his/her review of the rebar drawings.
The fabricator is obligated to cut/bend bars in accordance with #2.
The installer is obligated to install the bars in accordance with BOTH the contract drawings and the rebar drawings. Realistically, the latter should carry more weight as changes are often made in the review process that will never be reflected in updated contract drawings.
