Contracts

What is a flow-down clause in construction?

A flow-down clause is a subcontract provision that binds the subcontractor to the general contractor's obligations under the prime contract, as far as they apply to the sub's work.

Two construction professionals review paper plans beside a tablet at a jobsite workbench.
Plan reviews connect field conditions, drawings, and the next decisions on a job. AI-generated illustration.

A flow-down clause (also called a conduit or incorporation clause) says, in effect: whatever the GC owes the owner for this scope, the sub owes the GC. It usually incorporates the prime contract by reference and makes the subcontractor assume the same obligations and responsibilities toward the GC that the GC has toward the owner. Some flow-down clauses also give the sub the GC's rights against the owner. Many do not.

The point is to avoid gaps. If the owner requires a 2-year warranty, specific insurance, or 7-day notice of claims, the GC does not want a subcontract that promises less.

Flow-downs cover more than legal terms. Schedule requirements, safety programs, submittal procedures, closeout documents, and insurance limits often come into the subcontract the same way.

Required flow-downs on federal and public work

Some flow-downs are not optional. On federal and federally funded work, regulations require certain clauses to pass down to every tier.

Examples of required federal flow-downs
RequirementWhat must flow down
Davis-Bacon labor standards, 29 CFR 5.5(a)(6)The labor standards clauses and the applicable wage determinations, in all subcontracts and lower-tier subcontracts. The prime is responsible for compliance by its subs at every tier
E-Verify, FAR 52.222-54The clause, in subcontracts for services or construction over $3,500 for work performed in the United States

Missing a required flow-down does not make the requirement go away. On a Davis-Bacon job, the prime can be on the hook for a sub's unpaid prevailing wages whether or not the subcontract mentioned them.

How a flow-down plays out on a real job

Say a drywall sub signs a $380,000 subcontract on a private office building. The subcontract has one sentence incorporating the owner-GC contract, which the sub never asked to see. Two months in, the GC passes down a liquidated damages assessment of $1,500 a day for late completion and points to the prime contract, which gives the owner 48 hours' notice for claims. The sub's delay notice went out on day four. Because the prime contract terms flowed down, the sub may be bound to a notice period and a damages rate it never read.

What subcontractors should check

  1. Ask for the prime contract, or at least the general and supplementary conditions, before signing.
  2. Check claim and notice deadlines. Short owner deadlines can become even shorter in practice once the GC adds its own review time.
  3. Look for one-way flow-downs that pass down the GC's obligations but not its rights, such as rights to time extensions or to dispute owner decisions.
  4. Check pay-if-paid, indemnity, and no damages for delay language that may come in through the flow-down.
  5. Pass the clause down to your own sub-subcontractors and suppliers so you are not holding obligations you cannot pass on.

Frequently asked questions

Is a flow-down clause enforceable?

Generally yes, though courts often limit it to obligations related to the subcontractor's scope of work and may read conflicting terms against the drafter. State law varies.

Do flow-down clauses give subcontractors the GC's rights too?

Only if the clause says so. Some flow-downs are two-way and pass down the GC's rights against the owner; many pass down only obligations.

Which clauses must flow down on federal construction jobs?

Several, including the Davis-Bacon labor standards clauses under 29 CFR 5.5 and FAR 52.222-54 E-Verify for subcontracts over $3,500 for services or construction performed in the United States. The prime contract lists the rest.

What if the subcontract conflicts with the prime contract?

Many subcontracts include an order of precedence clause, often saying the stricter requirement applies. Read both documents.
