- Classification Identifiers (Union and Non-Union Rates)

The body of each wage determination lists the classifications and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination. The classifications are listed in alphabetical order of "identifiers" that indicate whether particular rates are union majority or survey weighted average wage rates.

Some wage determinations contain only survey weighted average wage rates, some contain only union-negotiated majority wage rates, and others contain both union majority and survey weighted average wage rates that have been found to be prevailing in the area for the type of construction covered by the wage determination.

Union Identifiers

  1. An identifier beginning with characters other than SU denotes that the union classification(s) and wage rate(s) have been found prevailing. The first four letters indicate the international union for the local union that negotiated the wage rates listed under that identifier (see listing below). The four-digit number that follows indicates the local union number.
    1. Example:

      PLUM0198-005 01/01/2013
      ST. JAMES PARISH (Northwestern Portion):
                                                                                        Rates Fringes
      PLUMBER (excluding pipe laying)..........................$ 25.04 10.42

      The identifier is PLUM0198-005 07/01/2007. PLUM = Plumbers; 0198 = the local union number (district council number where applicable); and 005 = internal number used in processing the wage determination. The date following these characters is the effective date of the most current negotiated rate.

  2. Special identifiers are necessary for two trades because the same local union number(s) is accompanied by different wage rates in different states. Bricklayers local union numbers are not unique nationwide, but are unique within each State. Similarly, Sprinkler Fitters Local Union No. 699 has negotiated different wage rates in each State within its territorial jurisdiction. Therefore, the identifiers for the Bricklayers unions are in the format "BR + state abbreviation," (referenced below as BRXX), and the identifier "SF + state abbreviation" is used for Sprinkler Fitter Local No. 669's rates.
  3. It is common for many local unions to negotiate wage rates for more than one classification. Where this is done, all the classifications for which that union's wage rates are determined to be prevailing will appear under the identifier for that union.
    1. Example:

      The same union may negotiate wage and fringe benefits for painters and glaziers. In such a case, the wage rate for the glazier, as well as that for the painter, will be found under an identifier beginning with "PAIN" (if the union rates were found prevailing for both glaziers and painters). Similarly, users may need to look under an identifier beginning with "CARP" to find not only rates for carpenters, but also those for millwrights, piledrivermen, and (marine) divers.

    Union Identifier Code Abbreviations

    Following are the identifier codes used to reference the various craft unions. Examples of classifications for which their local unions commonly negotiate wage and fringe benefit rates are shown in parentheses.

      ASBE = International Association of Heat and Frost Insulators and Asbestos Workers

      BOIL = International Brotherhood of Boiler Makers, Iron Shipbuilders, Blacksmiths, Forgers and Helpers

      BRXX = International Union of Bricklayers, and Allied Craftsmen (bricklayers, cement masons, stone masons, tile, marble and terrazzo workers)

      CARP = United Brotherhood of Carpenters and Joiners of America (carpenters, millwrights, piledrivermen, soft floor layers, divers)

      ELEC = International Brotherhood of Electrical Workers (electricians, communication systems installers, and other low voltage specialty workers)

      ELEV = International Union of Elevator Constructors

      ENGI = International Union of Operating Engineers (operators of various types of power equipment)

      IRON = International Association of Bridge, Structural and Ornamental Iron Workers

      LABO = Laborers' International Union of North America

      PAIN = International Brotherhood of Painters and Allied Trades (painters, drywall finishers, glaziers, soft floor layers)

      PLAS = Operative Plasterers' and Cement Masons' International Association of the United States and Canada (cement masons, plasterers)

    "Survey" Weighted Average Identifiers

    Classification(s) for which the union rate(s) were not determined to be prevailing are listed under an "SU" identifier. SU means the rates listed under that identifier were derived from survey data by computing weighted average rates, which could, for example, be based on only non-union contractors' wage rates or a mixture of union and non-union contractors' wage rates. (The data reported for such a classification and used in computing the prevailing rate may include both union and non-union data. Note that various classifications, for which survey rates have been determined to be prevailing, may be listed in alphabetical order under this identifier.


      SULA2004-007 05/13/2004
                                                             Rates Fringes
      CARPENTER (all other work).......$ 13.75 $2.60
      Common/Landscape.......................$ 9.88 $0
      Fence.............................................$ 11.24 $0
      Flagger............................................$ 8.58 $0
      Mason Tender.................................$ 7.25 $0
      Pipelayer.........................................$ 9.84 $0

The identifier is SULA2004-007 05/13/2004. SU indicates rates that are in most cases weighted average wage rates (or, occasionally, non-union contractor majority wage rates); LA indicates the state of Louisiana; 2004 is the year of the survey and 007 is an internal number used in producing the wage determination.

A 1993 or later date indicate the classification(s) and wage rate(s) under that identifier were issued in the GWD on that date.
