This is a long shot, but maybe somebody can help.
On a construction contract translated from Romanian, there is a charge for "squirrel drilling."
We need to explain it.
What I think it probably is is some kind of directional drilling direct bore - this involves installation of some water line.
But I can't figure out what could get translated as squirrel. Or, mistranslated as squirrel. I don't have the original document, just the translation.
