The prime contractor flowdown is how a main contractor passes down requirements, terms, and responsibilities to subcontractors. It ensures that every layer of the supply chain understands what they need to deliver, from technical specs to compliance rules. When done right, it keeps the whole project aligned and avoids costly misunderstandings or rework.
