The Missouri Contractor's Report of Construction Wage Rates is a legal document used to establish the prevailing wages for construction workers in the state of Missouri. This report is used in order to ensure that contractors are abiding by the state's labor laws. It contains wage rates for all classifications of workers, such as laborers, carpenters, electricians, plasterers, and masons. The report also contains wage rates for apprentices and journeymen, which are based on the average hourly wages and benefits for workers in the same classification. The report is updated periodically to reflect changes in the cost of living and the labor market. There are two types of Missouri Contractor's Report of Construction Wage Rates: the On-Site Report and the Off-Site Report. The On-Site Report is issued by the Missouri Department of Labor and Industrial Relations and contains wage rates for construction workers on public works projects. The Off-Site Report is issued by the Missouri Department of Labor and Industrial Relations and contains wage rates for construction workers on private works projects.
