Safety & OSHAaka: Occupational Safety and Health Administration

OSHA

In Plain English

The federal agency that sets and enforces workplace safety rules for U.S. construction sites.

Definition

The Occupational Safety and Health Administration (OSHA) is the federal agency within the U.S. Department of Labor responsible for ensuring safe and healthful working conditions for American workers. OSHA sets and enforces standards, provides training and outreach, and investigates workplace injuries and fatalities. In construction, OSHA 29 CFR Part 1926 is the primary regulatory standard. State-plan states operate their own OSHA-approved programs.

Why It Matters in Bidding

OSHA compliance is a direct cost driver in any responsible bid, because safety staffing, training, fall protection, equipment, and required programs must be carried in the general conditions rather than treated as overhead afterthoughts. A poor safety record raises a contractor's experience modification rate, which inflates workers' compensation premiums and erodes competitiveness on every future bid. Many owners also screen bidders by OSHA citation history and EMR, so a strong compliance posture affects prequalification, not just on-site risk.

Example

When building a high-rise bid, the estimator carries the cost of a full-time site safety manager, weekly toolbox talks, and guardrail systems in the general conditions because OSHA 29 CFR 1926 fall-protection requirements apply across the entire schedule.

Frequently Asked Questions

Construction work is governed primarily by 29 CFR Part 1926, which covers fall protection, excavation, scaffolding, electrical, and other site-specific hazards. General industry standards in Part 1910 can also apply in some situations. State-plan states enforce their own OSHA-approved standards that must be at least as effective as the federal rules.
Compliance costs, including safety personnel, training, fall protection, and required written programs, should be priced into general conditions. A contractor's citation history and experience modification rate also influence workers' compensation premiums and owner prequalification, so safety performance affects both direct bid cost and long-term competitiveness.
Some states run their own OSHA-approved occupational safety programs instead of relying solely on federal OSHA. These state plans must be at least as stringent as the federal standards and sometimes add requirements. Contractors bidding across state lines should confirm which agency has jurisdiction and whether any stricter local rules apply.
