Frank Murphy, Clifford Macevoy Company v. United States…
“ In a broad, generic sense a subcontractor includes anyone who has a contract to furnish labor or material to the prime contractor. In that sense Miller was a subcontractor. But under the more technical meaning, as established by usage in the building trades, a subcontractor is one who performs for and takes from the prime contractor a specific part of the labor or material requirements of the original contract, thus excluding ordinary laborers and materialmen. ”
