Who Controls Contingency, the Owner or the Contractor?

The conversation usually happens late, under pressure, when something has gone wrong and someone needs money. That is the worst possible moment to discover that the two parties have been using the same word to mean different things for eighteen months.

Why does the same word mean opposite things?

Because the frameworks were built to answer different institutional questions, and nobody reconciled them.

A 2026 review in Risks examined management reserves in United States government construction cost estimation and documents that GAO and the Department of Energy use the two central terms in effectively opposite senses. GAO associates contingency with unknown unknowns and management reserve with known unknowns; DOE's usage inverts that relationship. Both are internally coherent. Neither is wrong. A programme that inherits language from one and governance from the other cannot explain, under scrutiny, what its own reserve is for.

DOE's own training material adds a second distinction that is genuinely useful, and it is structural rather than semantic: management reserve is described as an amount of the total contract or project budget set aside for management control purposes by the contractor, while contingency is funds, not budget, held by the department outside the negotiated project scope, schedule and budget values. Note that this is training material rather than a directive, so it is weak as citable authority even though it is clear.

What is the workable pattern?

Separate the pots and name the holder of each. The distinction that survives contact with a real project is not unknown versus known unknowns, which people argue about endlessly, but who carries which risk.

The party carrying delivery risk holds a reserve inside the contract, drawn against execution variance within agreed scope. The party carrying funding risk holds a reserve outside the contract, drawn against scope change, external events and the possibility that the whole estimate was optimistic. Neither can quietly consume the other, and each has a named owner who can be asked what it is for.

Washington State DOT shows one institutional form of this. Its policy sets a legislative budget value and a lower operational value, at the 60th and 40th percentiles for projects under 100 million dollars and the 50th and 30th above that, and treats the difference between them explicitly as the project risk reserve. The reserve is visible, bounded, and separated from the working target, which makes drawing on it or returning it an event with a name.

FTA approaches it from the other end, requiring the sponsor to work from a stripped and adjusted base cost estimate with contingency removed before the risk model runs. That is the same principle applied to construction of the number rather than to its governance: contingency that cannot be located cannot be governed.

What happens when nobody owns it?

The reserve does not sit neutrally. It drifts toward being held, and then toward being spent late and defensively.

Ayub, Thaheem and Ullah examined contingency release decisions during execution and found managerial pressure to be a substantial driver, operating largely independently of objective project metrics. Ford had earlier modelled contingency management as a policy choice, comparing aggressive and conservative release strategies and showing that the choice has real consequences for project objectives. Put together: the decision is being made routinely, it matters, and it is frequently not being made on the analysis.

The incentive structure explains it without needing to assume anyone is behaving badly. Release contingency early and you own the decision if something later goes wrong. Hold it and no one is ever blamed for money that sat idle, because idle money does not generate an incident. Absent an explicit rule, every individual actor is behaving rationally and the aggregate outcome is capital held hostage.

What does a release authority actually look like?

Three sentences in the governance document, decided before the first request arrives.

Who may authorize a draw or a return, at what threshold, and by what escalation route above it. What evidence must accompany the request, which for a return should be a re-run of the model showing the required amount has fallen because named uncertainty resolved. And who is informed afterwards, so the decision is visible rather than absorbed.

Add a floor if the project is federally funded, because FTA requires preserved contingency curves defining minimum levels to be held as a function of project advancement. The floor and the release rule are complements: the floor stops premature depletion, the rule stops indefinite hoarding. Neither one alone produces managed contingency, which is the fuller argument in Releasing Contingency as Risks Retire.

Why is this an Authority problem?

Because everything here that could be solved by analysis already has been, and the behaviour has not changed.

A programme can know its P65, know its drawdown floor, and know precisely how much its reserve should have fallen this quarter, and still not move a dollar, because no one holds the standing to act on any of it. Naming a risk owner without giving that person authority produces the appearance of accountability and none of the substance, which is the argument in Risk Ownership Without Authority. Contingency is that pattern in its most measurable form, because the unmanaged asset has a number attached and appears on a report every month.

The diagnostic takes a minute. Ask three people who can authorize returning contingency to the organization. Three different answers, or the same hesitant one three times, tells you the reserve is being stored rather than managed.

What to do with this

Before the next contingency conversation, write down what your organization means by contingency and by management reserve, in one sentence each, and check whether the other party would sign the same two sentences. If they would not, you do not yet have a disagreement about money. You have a disagreement about words, and it is far cheaper to settle now.
