These contractors are ranked from classified permits, not keyword scrapes. We read each permit’s work-type, scope, and occupancy fields to place it in Commercial Alteration — so a filing that looks like a generic alteration lands in the right segment, and the ranking reflects real work. When the fields don’t support a confident call we mark it Unclassified — we never force a wrong segment to pad a contractor’s count.
