As-built verification: how to avoid surprises at closing – for historic centres
Many renovations get stuck on details that look minor: an incorrect permit path, outdated drawings or a hidden constraint. In Sicily, coastal exposure and mixed building stock make early checks even more important.
Permits and documentation
Choose the correct route (CILA, SCIA or permit) based on the scope and the building context.
Check constraints and approvals (heritage, landscape, condominium) before appointing contractors.
- How to document decisions
- How to keep changes under control
- Constraints to check early
Technical details that matter
Focus on critical junctions (waterproofing, thermal bridges, services) because most post-handover issues start there.
Design for durability and maintenance: the best-looking solution is not useful if it does not last.
- Documents you should have
- Constraints to check early
- How to keep changes under control
Schedule and cost control
Track decisions on site: inspections, progress records and structured change management.
Set up a bill of quantities and specifications that describe works, materials and tolerances in measurable terms.
- How to keep changes under control
- Questions to ask contractors
- Constraints to check early
Where to start
Commission an accurate measured survey and clear drawings: without reliable measures, design is guesswork.
Collect the key documents (permits, drawings, cadastre) and check consistency between existing condition and authorised state.
- Documents you should have
- Questions to ask contractors
- How to keep changes under control
- You need a quick technical check before buying or signing.
- You must confirm the right permit path and missing documents.
- You want measurable specs to compare quotes properly.
- You started works and need to regain control of scope and changes.
- Mixing up cadastre updates and building permits (they are different).
- Ignoring waterproofing, slopes, ventilation and other “small” details.
- Applying standard solutions without reading the building context.
- No clear responsibilities between client, contractor and designers.
