I’ve often wondered just where the term “punch list” came from, and I’ve found a few sources that seem to make sense, while others not so much.
One person claims it came from the telephone installer process of “punching down” terminals on a block. That seems a bit of a stretch though. A blog writer said it had to do with the term ‘punch’ since it means to “punch something up” as in fix it.
Another blog writer thought it had something to do with a long forgotten practice. Apparently subcontractors used to each have their own hole punches that would punch a hole with a shape unique to them. They would use these punches to indicate they had corrected the deficiency that was their responsibility.
