Essential Prequalification Questionnaire Questions

A contractor can submit a clean EMR, a favorable TRIR, and a current certificate of insurance, then still arrive without a workable plan for the hazards on your site. That is the gap essential prequalification questionnaire questions must close. The purpose is not to collect a larger stack of PDFs. It is to establish whether a contractor can control risk before mobilization, and to create a decision record your safety, procurement, and audit teams can defend.

A useful prequalification questionnaire asks for claims that can be validated, distinguishes a past outcome from a present control, and applies the same criteria to comparable contractors. If a question does not affect qualification, risk scoring, conditional approval, or follow-up, it probably does not belong in the PQF.

What a Defensible Questionnaire Needs to Prove

Prequalification should answer four operational questions: Is the contractor a legitimate business with appropriate coverage? Does it have a functioning safety management system? Are the people assigned to the work trained and authorized? Can the contractor identify, plan for, and respond to the hazards involved?

That last question is where many legacy questionnaires fall short. TRIR, DART, LTIR, and EMR are relevant context, particularly when benchmarked against the contractor's SIC-code peers. But they are lagging measures. They tell you something about recorded outcomes, not whether a crew has completed a job hazard analysis for tomorrow's confined-space entry or whether supervisors are closing safety observations in the field.

Ask for both. Then weight the evidence accordingly. A contractor with a higher-than-expected incident rate may need corrective-action review, while a contractor with no incidents but no documented pre-job planning should not receive a free pass.

Essential Prequalification Questionnaire Questions

1. What work will you perform, where, and under whose supervision?

Start with scope. Ask contractors to identify the services they will perform, anticipated crew size, locations, project duration, shift pattern, and the high-hazard tasks involved. Request the name and role of the person responsible for field safety and the onsite supervisor.

This prevents a common failure: approving a contractor for general maintenance, then using that approval to support energized electrical work, excavation, hot work, or work at height. Qualification should be tied to scope and risk. A contractor may be qualified for one category of work and conditionally approved, or not approved, for another.

2. Can you provide evidence of an active safety management system?

Ask whether the contractor maintains written safety policies, a hazard communication program, emergency procedures, disciplinary expectations, and a process for updating policies after regulatory or operational changes. The better question is not simply whether documents exist. Ask when each policy was last reviewed, who approved it, and how it is communicated to field personnel.

Require the supporting documents where the work warrants them. A generic safety manual copied from a template is weak evidence. A current program with named responsibilities, revision dates, and procedures that match the contractor's actual work is materially stronger.

3. How do crews plan work before hazards are encountered?

This is a leading-indicator question. Ask: How do you complete pre-job planning, job hazard analyses, or activity hazard analyses? Who participates? When is the plan reviewed? What triggers a revision when site conditions change?

The response should show that planning happens at the crew level, not only in an office before a contract is awarded. Ask for recent, redacted examples of completed plans tied to similar work. Review whether hazards, controls, responsible persons, and worker acknowledgment are documented. For higher-risk scopes, require the contractor to submit a project-specific plan before access is granted.

4. How do you capture safety observations, near misses, and corrective actions?

A contractor that only reports recordable injuries is measuring failure after the fact. Ask how workers and supervisors report near misses, unsafe conditions, good catches, and safety observations. Then ask how the company assigns, tracks, verifies, and closes corrective actions.

Useful evidence includes a sample observation, a near-miss report, an action log, and proof that trends are reviewed by leadership. The goal is not to punish contractors for reporting. It is to identify whether they have a credible learning system. Low reporting can mean excellent control, but it can also mean workers do not believe reporting is safe or worthwhile. The questionnaire should create room to investigate that distinction.

5. What training and credentials will the assigned workers hold?

Ask for the training requirements associated with the proposed scope, along with worker-level completion records, expiration dates, and trainer credentials where applicable. This may include OSHA training, operator qualifications, competent-person designations, confined-space training, fall protection, lockout/tagout, respirator use, first aid, or client-required site orientation.

Do not accept a contractor statement that all employees are trained as final proof. Training records need to be traceable to the individual worker who will enter the site. The same applies to licenses and certifications. Qualification decisions become much easier to defend when expired credentials generate renewal alerts before a worker reaches the gate.

6. Is insurance coverage current and adequate for this scope?

Ask for an ACORD-25 certificate of insurance and identify the coverage types, limits, effective dates, carriers, and endorsements required by your contract and risk profile. Depending on the work, that may include general liability, workers' compensation, auto liability, umbrella coverage, professional liability, pollution liability, or other specialized coverage.

A COI alone does not prove every contractual requirement has been met. The questionnaire should capture whether additional insured status, waiver of subrogation, primary and noncontributory wording, or notice requirements apply. Validate the certificate against the actual requirements and monitor expiration dates. Manual email chasing is not a control.

7. How do you manage subcontractors and temporary labor?

If a contractor uses lower-tier subcontractors, staffing agencies, or leased employees, ask who employs the workers, who verifies their training, who supervises them, and whether the same prequalification standards flow down. A prime contractor's good safety program does not automatically extend to every lower-tier employer.

Require disclosure before mobilization, not after an incident. For critical work, require lower-tier contractors to submit their own qualification evidence. This adds administrative effort, but the trade-off is clear: unknown employers and unverified worker credentials create an avoidable gap in site control.

8. What incidents, citations, and corrective actions require review?

Ask for OSHA recordable data, DART, TRIR, LTIR, EMR, citations, serious incidents, fatalities, and open enforcement actions over a defined period. Pair the numbers with questions about investigation quality, corrective actions, and whether those actions were verified in the field.

Use SIC benchmarking to interpret incident rates fairly. A specialty contractor performing high-exposure work should not be assessed against a low-hazard office service provider. At the same time, a favorable benchmark should not outweigh missing evidence of planning, observation, leadership engagement, and training compliance.

Turn Responses Into Decision Logic

The questionnaire is only as useful as the rules behind it. Define what produces approval, conditional approval, rejection, or escalation before responses arrive. For example, an expired COI may be a hard stop. A missing toolbox-talk sample may trigger a document request. A recent serious incident may require EHS review and a corrective-action interview rather than automatic disqualification.

Make the score visible enough that contractors understand how to improve it. Score validated leading indicators such as pre-job planning, safety observations, leadership engagement, near-miss reporting, and toolbox talks more heavily than isolated lagging statistics. Keep source documents attached to each response, record who reviewed them, and preserve the reason for every exception.

That discipline is fairer to contractors and safer for hiring clients. Contractors earn credit for controls they can demonstrate, rather than being judged through an opaque formula. Hiring organizations gain an audit trail that shows not just who was approved, but why.

Questions That Create Work Without Reducing Risk

Avoid duplicate questions that collect the same information under different labels. Avoid asking for every policy a contractor has ever written when only certain programs apply to the work. And do not request employee medical details, Social Security numbers, or other unnecessary personal information in a prequalification workflow.

Also avoid yes-or-no questions without a request for evidence, ownership, or dates. A yes to Do you conduct safety meetings? reveals little. Ask how often meetings occur, who leads them, how attendance is recorded, and provide a recent example. Specific questions produce specific evidence.

The best questionnaire does not make qualification harder for its own sake. It gives capable contractors a direct way to show the proof clients demand and contractors earn, while exposing the controls that need attention before workers arrive on site.
