Subcontractor prequalification

Subcontractor prequalification is the process of vetting a subcontractor's capacity, financial standing, and safety record before inviting it to bid.

Also written as prequalification, prequal, subcontractor prequal.

What gets checked typically includes bonding capacity, financial statements, insurance limits, safety history including the experience modification rate, current backlog relative to capacity, and references on comparable work.

It happens before bidding rather than during comparison, and it answers a different question. Leveling asks which price is genuinely lowest. Prequalification asks which bidders should have been asked in the first place — because the lowest number is worth nothing from a subcontractor that cannot finance the work, staff it, or finish it.

Doing it up front is also what keeps the comparison honest. A bid from an unqualified contractor drags the apparent market price down and makes every other bid look expensive against a number that was never really available.
