New MIOSHA standard adds stricter inspection and worker training mandates with enforcement delayed until September.

State officials have finalized sweeping amendments to Michigan’s concrete construction safety regulations, introducing stricter training mandates and structural oversight for worksites across the state.

The changes, announced by the director of the Michigan Department of Labor and Economic Opportunity, update Construction Standard Part 25, Concrete Construction. The revised rules officially took effect June 22, but state regulators are delaying enforcement for 90 days to allow employers to adjust. Compliance enforcement is scheduled to begin Sept. 21.

Under the updated framework, employers face new requirements to verify and document that employees have received task-specific training regarding concrete hazards from a qualified individual.

The revisions also target a wide range of operational hazards, clarifying support and stability requirements for reinforcing steel and introducing tighter controls for site access and layouts in active construction zones. Additionally, the standard places a heavier emphasis on worker exposure risks and suspended loads during mixing, pouring and floating procedures.

For structural operations, the amendments implement stricter inspection and documentation guidelines for forms, shoring and reshoring before any concrete can be placed. The state also revised safety language for flying forms operations, specifically addressing rigging procedures and worker positioning.

Equipment loading limits and manufacturer guidelines for tendon tensioning operations have also been clarified under the new rules. Full copies of the revised standard are available publicly through the Michigan Occupational Safety and Health Administration.
