As a Davis-Bacon state, federal Davis-Bacon rules preside over New Hampshire. Prevailing Wage rates are in effect for the life of the project and do not have pre-determined increases. However, special determinations can be requested by the awarding body on a per project basis. If the awarding body requests a special determination, the procedure will take at least 30 days.  These special determinations are specific to your particular Prevailing Wage job, and can contain pre-determined increases.  The awarding body or contracting agency will provide the contractors with these special determinations.
