Services · Site supervision
The direttore dei lavori works for you, not for the builder.
Site supervision and contract accounting for renovations and new builds in the province of Chieti: written site records, dated photographs, certified payment stages and a final file that stays with you.
The role
What a direttore dei lavori actually does
The direttore dei lavori is the technician appointed by the client to supervise construction on the client's behalf, checking that what is built matches the approved design, the building contract and Italian law. Ivan Nozzi is an Italian-registered civil engineer — Ingegnere, the professional title held by engineers entered on a provincial register, in his case the Ordine degli Ingegneri della Provincia di Chieti, Section A, civil and environmental sector, no. 2489 — and takes this role on renovations and new builds in the province of Chieti and the Pescara area.
The appointment comes from you and is paid by you. That is the whole design of the role: the person checking the work must not depend on the person doing it. Builders frequently offer to bring their own supervisor, and the offer sounds helpful. It stops sounding helpful at the moment a stage payment should not be signed.
Supervision also carries the contabilità dei lavori — contract accounting. This is the formal measurement of what has been built and the paperwork that releases each instalment. It is the least visible part of the job and the part that prevents most disputes on a private contract, because it fixes payment to measured work rather than to a builder's invoice.
It is worth being equally clear about the limits. Supervision is not continuous attendance on site, it does not replace the contractor's liability for execution, and it does not direct the contractor's workforce. No engineer can promise in advance that a building will be free of defects. What the appointment produces is documented verification: every check leaves a dated written trace. Where the work requires other technical appointments under Italian law, those are made separately by the client.
Scope
What the appointment covers
Site supervision means verifiable activity and documents that remain yours. This is what happens on site and what is handed over at the end.
- Checking that what is being built matches the approved drawings: dimensions, levels, build-ups and materials, not only the general shape.
- Verifying materials as they arrive: delivery notes, CE marking, declarations of performance and the certificates required for each supply.
- Site visits recorded in writing, with dated photographs filed and shared, so each stage leaves a record rather than a recollection.
- Written instructions to the contractor (ordini di servizio) when something has to be put right, with a deadline and a follow-up check.
- Contract accounting: measurements taken on site, the register of works, stage applications (SAL) and the payment certificate that releases each instalment.
- Handling variations: what they cost, whether they affect the building permit, and re-filing before the work proceeds rather than after it is buried.
- Keeping the filed paperwork aligned with the building as actually constructed: revised drawings, the fine lavori completion notice and cadastral updating where required.
- A final file handed to you: the closing account, drawings updated to the built state, and the certificates and declarations collected from contractor and installers.
Independence is the service
The direttore dei lavori is appointed and paid by the client and answers to the client: where the person verifying the work depends on the company carrying it out, what remains is the appearance of supervision rather than supervision. The appointment therefore comes to you as a written mandate setting out the activity, the visit pattern and the documents produced. If you choose EDIL NOZZI S.R.L. as your contractor — a separate company from my professional practice, with its own VAT number — the relationship is disclosed in writing before the appointment, the choice of contractor stays entirely yours, and the supervision role continues to be exercised in your interest.

Who answers for what
A private building contract in Italy puts distinct obligations on four parties, and blurring them is the most common source of site disputes.
| Role | Answerable for | Not part of the role |
|---|---|---|
| Progettista — designer | The content of the design: planning and building compliance of the drawings, technical choices, calculations and the computo metrico. | Choosing the contractor, or how the site is organised day to day. |
| Direttore dei lavori — supervisor | Supervision on the client's behalf: works against design, material checks, written records, contract accounting and stage payments. | Directing the contractor's workforce, substituting for it on means and methods, or being on site continuously. |
| Impresa — contractor | Execution to the standard of the trade, workforce, plant, the materials it supplies and the contractual programme. | Deciding variations on its own, or certifying its own accounts. |
| Committente — client | Appointing the technicians, approving variations, paying, and the fees and charges due to the comune. | Technical verification, which is precisely what the appointments delegate. |
This is the ordinary allocation on a private contract. The building contract can move specific obligations; where it does, the contract prevails over any table.
Owners abroad
Supervision when you are not in Italy
Site supervision works for an owner living outside Italy provided the reporting rhythm is agreed before work starts rather than improvised once it has. If you are renovating in Abruzzo from Britain, Germany or the Netherlands you cannot watch the site yourself, and the appointment is what replaces watching it.
The agreed update has a fixed shape and carries three things: what has been built since the last visit, dated photographs of anything about to be covered up, and the list of decisions waiting on you, each with the date by which an answer is needed. A vague photo dump is not a report and does not help you decide anything.
Photographs matter most immediately before things are closed. Reinforcement before the pour, services before plaster, waterproofing before the screed. Once a layer is covered, verifying it means opening it again, and by then any argument with the contractor starts from a losing position.
Some decisions stay with you and cannot be delegated: approving variations that change cost or affect the building permit, authorising payment after each stage application, choosing finishes, and signing the building contract itself. I can hold a written authority to file with the comune on your behalf. I cannot decide how much you spend.
Site records, instructions to the contractor and the accounts are written in Italian, because that is the language in which they carry weight with contractors and municipal offices. Write to me in English or German whenever that is easier: your message is read and answered. The written updates come back in Italian, and site meetings and calls are held in Italian, so plan for someone to interpret — bring your own, or ask me to suggest one locally.
Questions
Questions buyers and owners ask
Can the builder appoint the direttore dei lavori?
The appointment belongs to the client, who also pays for it. A builder may propose a name, and often will. But a supervisor whose future workload depends on the company being inspected has an obvious reason not to look too closely. The conflict is not theoretical: it appears at the exact moment a section has to be redone, or a stage payment should not be signed.
How often are site visits?
The pattern is set in the written appointment and follows the work rather than the calendar. Visits concentrate on stages that cannot be checked later without demolition: reinforcement before concrete is poured, services before walls are closed, waterproofing before screeds go down. Continuous presence is not part of the role and is not promised. What counts is that each visit produces a written record and dated photographs.
What happens if the works deviate from the design?
The deviation is recorded in writing and the contractor receives a formal instruction with a deadline to put it right. If the change is technically sound it becomes a variation: priced, checked against the building permit and re-filed before work continues where the permit is affected. Unresolved deviations stay attached to the property and become the owner's problem at resale, long after the builder has moved on.
What is contract accounting, and why does it matter?
Contract accounting, contabilità dei lavori, is the formal measurement of what has actually been built and the basis on which instalments are paid. It runs through measurements taken on site, a register of works, stage applications known as SAL, and a payment certificate signed by the supervisor. Its purpose is that you pay for completed work in the quantity completed, rather than releasing money against an invoice.
Can you supervise a project designed by someone else?
Yes. The first step is to read the design, the building permit and the construction contract, and to tell you in writing what is consistent and what is not, before anything is signed. Where the drawings are too thin to allow real verification on site, I will say so at that point. Taking on supervision of an inadequate design moves the exposure onto you, not onto whoever drew it.
Next step
Before you sign the building contract
The useful moment to appoint a supervisor is before the contractor starts, not after. Once work is covered up, supervision is left checking what has already been buried. Tell me what the project is, where the property is, and how far along you are.
