How do you prequalify a subcontractor?
By checking capacity, not just paperwork. Financials, licences and classification grades, insurance and bonding, HSE history, current workload, references. Then grade it, date it, and — the part almost everyone skips — refresh it on triggers rather than anniversaries. Prequalification is a snapshot, and vendor risk is a movie.
The questions that actually predict delivery
Can they fund the work before you pay them? That is a financial question, and it is the one that decides whether they finish. What else are they carrying right now — because a subcontractor with capacity on paper and five live packages elsewhere does not have capacity. What is their bonding line, and would their bank extend it?
What does their HSE history look like? Not their policy — their record. Incident rates, audit scores, violation trends. A firm that cuts supervision under financial pressure shows it in the safety data before it shows it anywhere else.
The Gulf regulatory layer
A valid trade licence — with the correct activity codes, because a licence that does not cover the activity is not a licence for this work. Municipal classification grades. ICV certification, which carries a 14-month validity tied to audited financials.
Track those expiries exactly the way you track insurance, because working with a lapsed licence can invalidate the contract you are relying on. That is not an administrative inconvenience. It is the contract evaporating.
And then keep looking
The prequalified-then-collapsed pattern is well documented — firms have passed framework prequalification weeks before entering insolvency. An annual refresh cannot catch that, because the information it needed did not exist a year ago.
So the check that matters is continuous, and it is trigger-based: payment slowdowns, thinning labour, sub-tier suppliers calling you, insurances lapsing, a refused bond renewal. Prequalification tells you who they were. Monitoring tells you who they are.
