As a GC that does commercial work, I could totally picture one of my subs doing that

As a subcontractor that has used concret coring companies a lot, I can see some new guy getting out to a site and realizing that he didn't bring the big blade for the slab sawing job, decided to McGiver it. It's a lot funnier though if you think it was someone's attempt to replicate a "change cloud".

Woulda sucked based on the size of rev clouds that I draw.
