As named in the permit records — identifiers we surface, not verified state licensure.
Demef Construction CORP has 32 permits, but too few carry a value we can stand behind — so we publish — for reliable value, never a guess. They still rank by volume; the dollar figure stays honest.
Monthly value isn’t shown: too few of Demef Construction CORP’s permits carry a reliable valuation, so we publish the count trend only rather than a value line built from gaps.
