Your Virginia Davis-Bacon general determinations have no pre-determined increases for prevailing wage public works projects.  But while prevailing wages are good for the duration of the project, the awarding body can request special determinations on a per project basis.  The special determinations are specific to the particular DBRA job you are working on, and COULD contain pre-determined increases.  Special determinations will be provided to you by your contracting agency or awarding body in Virginia.  Please note that the process for requesting a special determination takes at least 30 days.
