Good subcontractors don't always lose tenders because they lack experience. They lose them because they don't reduce uncertainty.

Programmes that do not align with the main contractor's critical path
Logistics described, but not clearly demonstrated
Risks acknowledged, but not actively managed
Main contractors aren't just buying scope. They're buying certainty.
