Preventive archaeology: development-operation dossier
An archaeology-before-development dossier starts with the actual project footprint and authority prescription. France’s preventive-archaeology stages must be distinguished from Switzerland’s cantonal investigation and works frameworks. Identify the required operation, responsible bodies, access, programme and timetable before comparing costs and conditions. Preserve the decisions allowing or changing development. A prescribed investigation differs from an unexpected discovery made later, and its cost allocation cannot be imported across jurisdictions.

What investigation, excavation or project modification is prescribed?
France: distinguish diagnostic survey, excavation and project adaptation in the decision. Switzerland: record the investigation actually requested; the Vaud guide is a cantonal example rather than a uniform national operation sequence.

Which project footprint and archaeological prescription are concerned?
France: connect development footprint and parcels to the archaeological prescription under L521-1. Switzerland: identify the canton and actual project requirement; a federal heritage reference alone does not establish the cantonal preventive procedure.

Switzerland: record the investigation actually requested; the Vaud guide is a cantonal example rather than a uniform national operation sequence. |
| Who commissions, authorises and performs the operation? | France: L522-1 identifies State prescription and scientific oversight; separate authority and operator. Switzerland: identify the ordering service, authorisation and investigator from local documents instead of importing French institutional roles. |
| Which programme, agreement and access documents govern the work? | France: align programme, agreement, access and work phases. Switzerland: retain the equivalent project and access documents for the canton; a construction timetable does not demonstrate the archaeological team’s authority to enter every parcel. |

What costs and duties follow the selected national or cantonal procedure?
France: ministry guidance distinguishes developer excavation costs and conditional FNAP support. Switzerland: cost allocation requires the applicable cantonal basis and decision; no French funding rule or national Swiss allocation is inferred.

Which official provision helps explain this situation?
An archaeology-before-development dossier starts with the actual project footprint and authority prescription. France’s preventive-archaeology stages must be distinguished from Switzerland’s cantonal investigation and works frameworks. Identify the required operation, responsible bodies, access, programme and timetable before comparing costs and conditions. Preserve the decisions allowing or changing development. A prescribed investigation differs from an unexpected discovery made later, and its cost allocation cannot be imported across jurisdictions.
Which findings change the operation or development timetable?
France: connect findings and subsequent prescriptions to project changes. Switzerland: do the same for the actual cantonal investigation; a scientific observation and the decision allowing development to proceed remain different records.

What decision permits continuation or changes the constraints?
France: retain the decision governing continuation rather than assuming completion removes all constraints. Switzerland: establish the competent service’s actual continuation conditions; a report or team departure alone does not prove clearance.

How is prescribed investigation distinct from an accidental discovery?
France: prescribed preventive archaeology differs from an unexpected discovery notification. Switzerland: preserve the same task distinction within the local framework; this preparation does not replace the separate handling of a chance find.
