Safety prequalification helps a contractor understand whether a subcontractor has the systems, personnel, and resources needed for the planned work. It should not be reduced to one incident rate or a yes-or-no questionnaire. Numbers can identify areas for review, but they do not explain the conditions behind the data.

A balanced process combines lagging indicators, leading indicators, written programs, interviews, and project-specific capability.

Review performance data in context
Contractors may review workers’ compensation experience, injury and illness records, citations, claims, and serious incidents. Trends over several years can be more useful than a single number.

Ask the subcontractor to explain significant events, corrective actions, and improvements. A company that openly identifies lessons may present less risk than one with incomplete or inconsistent records.

Evaluate written programs
Request the IIPP, Code of Safe Practices, heat illness plan, respiratory protection program, fall protection procedures, silica plan, lead procedures, emergency plan, and other programs relevant to the scope.

The review should determine whether the documents are current, specific to the employer’s operations, and supported by forms and records. Generic manuals with another company’s name or outdated contacts are warning signs.

Verify training and qualified personnel
Identify required competent persons, qualified persons, equipment operators, first-aid providers, and supervisors. Confirm that qualifications match the planned work and will be available on the project.

Review how the subcontractor tracks training, certifications, expirations, and retraining.

Assess field implementation
Ask how inspections are conducted, how hazards are corrected, who can stop work, how near misses are reported, and how supervisors are held accountable. References or prior project observations can help verify whether the written program is actually used.

For high-risk work, a pre-award interview with the project manager, superintendent, and safety representative may be appropriate.

Use risk-based approval conditions
Prequalification does not always have to result in approval or rejection. The general contractor may require additional planning, dedicated safety staff, more frequent inspections, specific training, or submission of engineered procedures before mobilization.

Conditions should be written, assigned, and verified before the work begins.
