Mississippi is governed by federal Davis-Bacon rules as it is a Davis-Bacon state. While generally, determinations have no pre-determined increases (the Prevailing Wage rates are good for the life of the project) special determinations can be requested by the awarding body on a per project basis. If the awarding body does ask for a special determination, please be aware that this process will take at least 30 days.  These special determinations will be specific to your particular Mississippi DBRA job, and could contain pre-determined increases.  The contracting agency or awarding body will provide the contractors with these special determinations.
