we've carried a 60ft maximum spacing for construction joints for concrete retaining walls for decades but we don't know where this originated. We've noted that many other firms carry this same requirement and we often get pushback from contractors.

from our research, we cant find anything concrete (ahem) on the subject.

does anyone know where this might have originated or where i can find some guidelines? CRSI retaining wall guide and ACI 224.3 do not seem to be of help.

It would seem to me that contraction joint spacing is far more critical and maybe construction joint spacing could be stretched.

thoughts?

I am not sure there is a definitive guide but there are lots of references.

And here is something more in line with the spacing you gave.

It's either control the spacing of contraction joints or increase reinforcement to limit crack width. There is no need for construction joints if the contraction joints are done properly.
