A list of Davis-Bacon Wage Determinations is published by the US Government Printing Office by state.  You can find the current Prevailing Wage for Iowa here. The Iowa Wage Determination you are supposed to use for your job may be different than the one on the GPO website.  As a result, you should ALWAYS refer to the bid spec to insure you are using the correct Wage Determination for your Prevailing Wage job in Iowa!
