What to check before choosing a construction subcontracting partner
Handing off a defined scope to a subcontractor means handing off real execution risk. A short, practical checklist for main contractors evaluating who to trust with that scope.
1. Can they show a clean compliance footing?
Before anything else, confirm a subcontractor’s commercial registration is active, their VAT registration is current, and they’re aligned with the labour and social insurance systems (GOSI, Qiwa) relevant to the workforce they’ll deploy. This isn’t a formality — a subcontractor with gaps here can create liability that lands back on the main contractor.
2. Do they own the equipment and manpower behind the scope, or subcontract it further?
Ask directly whether the subcontractor executes the scope with their own equipment and workforce, or whether they’ll be sourcing a further layer of sub-subcontractors. Each additional layer adds coordination risk and makes it harder to hold anyone accountable when something goes wrong on site.
3. Can they mobilize on your actual timeline?
A subcontractor’s past project list matters less than their ability to mobilize equipment and labour against your specific schedule. Ask about lead times for equipment and workforce deployment, and be specific about your project’s actual start date and any known peak-demand periods.
4. Is communication going to work in practice?
On bilingual sites, day-to-day coordination between site supervisors, subcontractor crews and the main contractor’s team needs to work in both Arabic and English without constant translation delays. This is easy to overlook in a proposal review and expensive to discover mid-project.
5. What’s the accountability structure if something goes wrong?
Confirm, in writing, who is accountable for defects, delays or rework tied to the subcontracted scope, and how that’s handled contractually. A subcontractor who can answer this clearly before the contract is signed is usually easier to work with once the project is underway.
The bottom line
None of this replaces normal commercial due diligence, but these five checks tend to surface the issues that matter most once work is actually underway — not just on paper.
