NCCI Code 5057

The NCCI workers compensation classification for iron or steel erection work, including tower erection. This code carries one of the highest base rates in the NCCI system due to the extreme fall exposure and heavy rigging operations involved. Tower contractors whose primary work involves erecting new structures from the ground up are typically classified under 5057, with base rates ranging from $25 to $45 per $100 of payroll depending on the state.
