Title: RE: Rebar placing drawings

William,

I'm somewhat particular about this review.  I basically review all of the items you mentioned.

"(bar size &
spacing, bar lengths, no. of bars, splice lengths, hook lengths, stirrup
dimensions vs beam size/conc cover, configuration of bars at corners/joints,
extra bars at openings, etc)."

If I performed the actual design I've found it most efficient to perform this review myself, as I'm most intimate with the design.  On more significant projects (large commercial type) I specify that the contractor provide an additional 5% of rebar to be located on the site to be used at the engineers descrection during observation of the rebar placement.  I also make comments that are general "all lap splices to be Class A - Tension Lap splices, or 40*dB (minium) on the shop drawings if I see some specific details that are questionable.

Just my way of doing things.

Subject: Rebar placing drawings


I am interested in hearing how others perform reviews of shop drawing
submittals of rebar placing drawings. In how much detail do you review the
placing drawings? What are the items that you do/ do not review? (bar size &
spacing, bar lengths, no. of bars, splice lengths, hook lengths, stirrup
dimensions vs beam size/conc cover, configuration of bars at corners/joints,
extra bars at openings, etc). What items are the Contractor's
responsibility?

What is the "standard of care"? I've heard that some engineering firms state
in their specifications that they don't review rebar placing drawings - is
this common? Does it meet industry standards?

As my shop drawing review budgets get tighter, I'm reviewing the level of
detail that I use in reviewing such submittals. It seems that there is some
variability amongst different engineers. ACI and CRSI only seem to address
this issue in generalities without specifics on what should be reviewed.
What do you do?
