Chance find procedures: the stop-work obligation nobody rehearses

1. What the procedure is for

Cultural heritage assessment identifies what is known or predictable. Excavation regularly encounters what is neither: a burial with no surface indication, an artefact scatter, foundations of an earlier settlement. The chance find procedure is the standing instruction for that moment, and it exists because the moment cannot be planned for specifically — only prepared for generally. [1]

Its core is unvarying across projects. Work stops in the vicinity. The find is secured and not disturbed further. A defined person is notified. A qualified assessment is obtained. Work resumes only on authorisation, following whatever treatment is determined. Where national law requires notification of an antiquities authority, that requirement operates independently of the project's own procedure. [2]

The procedure is normally a short annex to a heritage management plan and is among the least-read documents on a project — until the day it is needed, when it is needed immediately and by someone who has never opened it.

2. Where it fails: the point of trigger

Chance find procedures rarely fail in drafting. They fail because the person who encounters the find is an excavator operator or a labourer, working to a daily target, for a subcontractor, possibly in a language other than that of the procedure, who has not been briefed on it and who correctly perceives that stopping work will cause trouble.

The incentive structure is unambiguous and points the wrong way. Reporting a find halts production, invites scrutiny and delays a programme the operator is measured against. Not reporting it costs nothing that anyone will observe, because the find's existence is known only to the person who has just destroyed it.

This makes the procedure's effectiveness a function of induction and of what happens after the first report, not of the document. A project where the first find is handled promptly, where the person who reported it is visibly not blamed, and where the crew's lost time is not charged against them will receive subsequent reports. One where the first report produces recrimination will receive no further reports, and will conclude that its corridor contains no heritage.

3. Human remains

Burials are the most common significant chance find on land-taking projects and the case that most exceeds preparation. They engage the technical question of archaeological significance, the legal question of what national law requires, and the social question of what the descendants require [1][2] — and the third is usually the one that governs whether the project can proceed.

Reburial is not a logistical exercise. It typically requires identification of descendants, agreement on a site, observance of rites that may be time-bound or seasonally constrained, and costs the family should not bear. Where the grave is unmarked and descendants cannot be identified, the community must be engaged about treatment of remains nobody can claim, which is slower and more sensitive than the identified case.

Procedures that anticipate this specify who engages the family, who pays, what the decision-making sequence is, and what happens if agreement cannot be reached quickly. Procedures that do not simply state that human remains will be dealt with in accordance with applicable law and local custom, which is a description of the problem rather than a plan for it.

4. Custody and the record

Once a find is secured, someone holds it, and custody carries obligations that projects often have not considered. Artefacts removed from a site must be documented at the point of removal — location, depth, context, condition — because that context is what makes them meaningful and it is destroyed by the removal itself.

Custody must then be traceable: who holds the material, where, under what conditions, and what the intended disposition is — the standard's own custody expectation. [3][4] In many jurisdictions the material is state property from the moment of discovery, and the project is a temporary custodian with duties rather than an owner with discretion. Where the find occurs on land also subject to resettlement, the project's broader assessment and management obligations under PS-1 govern how the two processes are coordinated. [8]

The chain-of-custody record is also the project's protection. Findings that material was lost, damaged or misappropriated are difficult to answer without a contemporaneous record, and the interval between discovery and final disposition is frequently long enough that the people involved at the start have left the project.

5. Conclusion

IFC's handbook and the World Bank's framework both treat the chance find procedure as a standard annex precisely because its cost of inclusion is negligible against the cost of an unmanaged discovery. [5][7] The chance find procedure is a document whose quality is almost irrelevant compared with whether the workforce has been inducted on it and whether the first invocation is handled well. Both are cheap and both are commonly skipped, because the procedure exists to satisfy a plan requirement rather than to be used.

Its distinguishing feature among safeguard instruments is that failure is invisible. An unreported burial leaves no trace in any register, and a project whose procedure never triggers cannot tell whether its corridor was empty or its workforce silent — a defect no citation of applicable standards in the project's documentation can substitute for.
