Measure. Strengthen. Build.
ABC Keystone deadline for STEP verification is December 15, 2026.
Founded in 1989 as a safety benchmarking and improvement tool, STEP has evolved into a world-class safety management system that dramatically improves safety performance among participants regardless of company size or type of work.
Participating ABC member firms measure their safety processes and policies on 25 key components through a detailed questionnaire to implement or enhance safety programs that reduce jobsite incidents.
MEASURE: Measure Your Performance on Key Components
STRENGTHEN: Strengthen and Expand Best Practices
