You’re here because someone is asking for it: prequal, insurance, or a bigger bid.

Common Questions After Calculating TRIR
What is OSHA TRIR?
TRIR stands for Total Recordable Incident Rate. It’s a standardized number that shows how many OSHA-recordable injuries and illnesses occur per 100 full-time workers in a year.
Is my TRIR “good”?
“Good” depends on your trade, client thresholds, and what you’re bidding. The bigger issue is what your TRIR makes people assume about your risk—and whether you can back up your story with proof.
If my TRIR is low, do I still need to worry?
Yes, because prequal and inspections aren’t only about the number. They’re about documentation, consistency, and whether your crews actually follow the basics on site.
What if I don’t have everything organized?
That’s the point of the free assessment. Most contractors are running lean. We’ll help you prioritize what matters and make proof easy to pull.
