Bill of quantities and specs: how to keep costs under control – with low-maintenance materials
Many renovations get stuck on details that look minor: an incorrect permit path, outdated drawings or a hidden constraint.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
Prepare a complete technical report to reduce requests for clarifications and delays.
Choose the correct route (CILA, SCIA or permit) based on the scope and the building context.
- How to keep changes under control
- How to document decisions
- Constraints to check early
Where to start
Commission an accurate measured survey and clear drawings: without reliable measures, design is guesswork.
Define priorities and constraints: what is mandatory, what is desirable and what can wait.
- Documents you should have
- Questions to ask contractors
- How to document decisions
Technical details that matter
Verify material compatibility with substrates, especially near the coast where salt air accelerates decay.
Focus on critical junctions (waterproofing, thermal bridges, services) because most post-handover issues start there.
- Documents you should have
- Questions to ask contractors
- Constraints to check early
Schedule and cost control
Set up a bill of quantities and specifications that describe works, materials and tolerances in measurable terms.
Build a realistic programme and the right sequence of trades.
- How to document decisions
- Documents you should have
- How to keep changes under control
- You are planning a renovation and want decisions backed by drawings and documents.
- You have doubts about compliance and cadastre alignment.
- You want one technical point of contact to coordinate the process.
- You need site supervision with clear records.
- Starting without a measured survey and without verifying the authorised state.
- Accepting vague quotations (generic items, undefined materials).
- Discovering constraints or approvals after works begin.
- Managing changes informally, without updated quantities and records.
