Contractor Prequalification Is Not Contractor Management

Insurance, WCB status, safety statistics, training records and program documents all help an employer decide whether a contractor looks capable of doing the work safely.

That matters, but it only tells you what the contractor looked like before the job started.

Once the contractor is on site, the question changes. Are they following the controls? Are they managing changes? Do the people doing the work understand the expectations? Is the supervisor actually watching the work that carries the highest risk?

The legal duties also depend on the role each party holds. Alberta OHS legislation assigns obligations to employers, contracting employers, owners, prime contractors, supervisors, workers, and other worksite parties. Prequalification does not replace those duties or the need to coordinate the work appropriately.

A company delivering office supplies should not go through the same safety review as a contractor doing excavation, energized work, lifting or confined space entry.

That creates paperwork without improving control. It also makes the contractor program harder to manage because the organization spends time reviewing low risk vendors while higher risk work may not get enough attention.

I prefer a risk based approach. Put contractors into practical categories and scale the requirements to the work they will actually perform.

A lot of contractor programs are strongest before the contract is awarded. Procurement collects the documents. Somebody reviews the safety information. The contractor gets approved.

Then the field supervisor receives the contractor and may have no idea what was reviewed, what conditions were placed on the approval or whether there were open concerns.

That handoff matters. The person supervising the work should know what they need to verify before the job starts and what they are expected to monitor once the work is underway.

A contractor orientation can cover site rules, emergency requirements, reporting expectations and general hazards. That is useful, but it does not replace planning the actual work.

Higher risk work needs coordination. Who controls the area? What equipment will be isolated? What other work is happening nearby? Who is responsible for traffic, permits, rescue planning or shutdown decisions? What happens if the scope changes?

Those are work planning questions. A sign in sheet from orientation does not answer them.

If the only contractor safety check happens before the contractor arrives, the organization has no good way to compare the paperwork with actual performance.

Oversight should be proportionate to the risk. That might be a supervisor check, a field observation, a permit review or a more formal inspection for higher risk work.

The point is not to stand over every contractor all day. The point is to verify that the controls the organization relied on during approval are actually being used.

One of the biggest missed opportunities in contractor management is losing what the organization learned after the job is done.

If a contractor had repeated safety issues, ignored site expectations, managed changes poorly or required constant intervention, that information should matter the next time they are considered for work.

The same is true for good performance. A contractor that plans well, communicates and responds quickly to issues should have that history available too.

Prequalification should tell you whether a contractor is eligible to start. Performance history should help you decide whether you want them back.

A practical contractor management system starts before award and finishes after the work is complete. It covers qualification, work planning, site expectations, field oversight, issue management and closeout.

If the process ends once the certificate of insurance and WCB clearance are saved, the organization is doing contractor administration. It is not yet managing contractor risk.

That distinction matters most on the jobs where the contractor can seriously hurt their own workers, your workers, the public or your operation. Those are the jobs where the management system needs to stay involved after the paperwork is approved.
