resteel placement tolerances
when placing rebar for vertical members, is a contact lap splice always required?  is there a tolerance on this?  i have already read aci-117 section 2.2, but have not fully understood all of the various points therein and will cogitate upon them with guidance.
when placing pre-tied column cages on the dowels of the previous lift sometimes the dowels may have been sqoze in a little too tightly and now there is a couple of inches between the dowels and the verts of the new cage.  or a section of pre-tied wall resteel the dowels may be off a little from the verts of the section be flown in.
all vertical bars require a full contact lap splice or is there a tolerance for distance between the these bars?  and if yes on the tolerance what part of aci-117 2.2 tells me this?
aci 318-05 12.14.2.3 gives maximum distance between non contact lap splice bars.
the maximum distance between non-contact lap slpices for beams are the same for walls and columns?
all vertical bars require a full contact lap splice or is there a tolerance for distance between the these bars?  and if yes on the tolerance what part of aci-117 2.2 or aci-318 tells me this?
am surprised i can't get an answer on this.
is it a dumb question?  a no brain-er?  there are no dumb questions but there sure are a lot of inquisitive idiots running around!
