Hooked Vertical Bars in Foundation Wall - Hook not long enough
Hooked Vertical Bars in Foundation Wall - Hook not long enough
(OP)
Same project I'm working on doing the PM. I came in after all of the rebar has been installed and the hooked length of the vertical #5 bars for the foundation walls are 6 inches. Code requires 12db which is 7.5 inches.
Foundation is as follows:
16" deep x 24" wide footing
36" tall x 6" wide stemwall - #5's vertical and horizontal at 12" o.c.
light framed construction on top
Are there any alternatives solutions other than removing the vertical bars and redoing them?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

1) Maybe there's enough bar length available to bend the hooks into code compliant 180's?
2) Perhaps the concrete strength could be increased such that straight bar embedment would work?
3) If it's not a shear friction thing, you could add more bars and use a prorated straight embedment capacity on each.
I think that all of these options would make the contractor feel sufficiently spanked if that is the goal.

This is the same engineer that is requiring 4,500 psi for a standard foundation to support a stick built 2 story structure that is only about 2,200 sqft.

It really is silly. We are taking out the bars now and replacing them...pretty costly miss on this one. I came in to the PM position after all the rebar was laid. Somehow they laid bars without a shop drawing submittal that was required.

I'm not sure. I spoke with the rebar supplier and concrete supplier and both were surprised when I pointed out the standard hooked detail and the required "db". My story is that they looked at the " 6" Minimum" length and just started bending. I'm guessing they have been doing this for a while and it finally got caught.
