232 - Trade Contracting

This subsector comprises establishments engaged in one aspect common to different structures, requiring specialized skills or equipment. They are known as trade contractors, and are classified by the specific component they contribute to the total structure or work. Trade contractors normally supply their specialized service under contract to a general contractor. In repair construction, and to a lesser degree in new construction, trade contractors, included in this subsector, may be engaged as "prime contractors", or jobbers, dealing directly with the principals involved.
