What Drives Business Interruption Premium for Structural Steel Contractors

The Business Interruption cost drivers underwriters watch on Structural Steel Contractors

Business Interruption premium for Structural Steel Contractors is moved primarily by five factors. In rough impact order:

• Height of work (steep slope, story count above 3)
• Completed-operations claim history within prior 3 years
• Subcontractor cost ratio without certificates of insurance
• Use of torch-down, hot-tar, or live-energy operations
• Operations in coastal / wind-rated zones

The first three explain 60-70% of the spread between a low-end and high-end premium on otherwise comparable Structural Steel Contractors. Carriers underwrite to these factors in that approximate order, with the rest serving as fine-tuning.
