The North American Industry Classification System (NAICS) size standards described in this section apply to all SBA programs unless otherwise specified in this Part. The size standards themselves are expressed either in number of employees or annual receipts in millions of dollars, unless otherwise specified. The number of employees or annual receipts indicates the maximum allowed for a concern and its affiliates to be considered small.
* To be considered small for purposes of Government procurement, a firm must perform at least 40 percent of the volume dredged with its own equipment or equipment owned by another small dredging concern.
** If a procurement requires the use of multiple specialty trade contractors ( i.e. , plumbing, painting, plastering, carpentry, etc .), and no specialty trade accounts for 50% or more of the value of the procurement, all such specialty trade contractors activities are considered a single activity and classified as Building and Property Specialty Trade Services.
