For prevailing wage public works projects in Arizona, Davis Bacon general determinations have no pre-determined increases. That means that the prevailing wages are good for the life of the project.  However, special determinations can be requested by the awarding body on a per project basis.  In the event that a special determination is requested, it could take at least 30 days to get a response. These special determinations will be specific to your particular DBRA job, and could contain pre-determined increases.  Your contracting agency or awarding body in Arizona will provide you with these special determinations.
