Why Springfield runs below the Illinois average
Construction wages in Springfield average $36.45 per hour against $39.27 statewide. Springfield sits below the Illinois average because the statewide figure is pulled up by higher-wage metros elsewhere in the state.
Labor is about 42% of the installed cost on this type of work, and it is the part that actually moves between markets. Materials are priced by national manufacturers and barely shift, which is why the gap between metros is narrower than wage differences alone suggest.
