Oklahoma Davis-Bacon Prevailing Wage rates are good 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 which will take at least 30 days.  The special determinations are specific to your particular Prevailing Wage job, and may include pre-determined increases.  The special determinations will be provided to the contractors by the awarding body or contracting agency.
