Survey, Restitution, and Restoration Project: 2026 Process Guide

1) Three Stages: Survey, Restitution, Restoration

Survey: Measured documentation of existing condition.
Restitution: Historical research and scientific proposals for missing elements.
Restoration: Intervention design for execution—materials, details, site methods.

2) Pre-Study and Advanced Documentation

The specification defines advanced documentation needs after pre-study—LiDAR, endoscopy, material analysis, plaster raking—justified in the pre-study report.

3) 2026 Technical Specification Requirements

Project files include architectural and structural reports, material analysis, photographic records, and conservation rationale. Documentation costs are included in cost estimates.

4) Survey Stage Essentials

Standard survey includes scales, sections, material legends, and damage maps. Incomplete survey causes costly revisions at restoration stage.

5) Restitution and Historical Research

Restitution relies on archives, old photographs, comparable buildings, and excavation finds. Boards reject proposals without scientific evidence.

6) Restoration Design and Execution Details

Restoration design includes work items, material specs, special technical specification draft, and quantity lists. We prepare execution design under our restoration services.

7) Conservation Board Approval

Files are submitted to regional boards. Revision requests are common; complete first submission shortens timeline.

8) Project Cost and Duration

Design preparation can represent 12–18% of total restoration budget. Duration ranges from 3 to 12 months depending on size and documentation scope.

9) Conclusion

The survey-restitution-restoration chain is the foundation of quality execution. Experienced authorship directly affects approval and site efficiency.
