Verifying technical and professional suitability is the formal and substantive assessment that a company or self-employed worker has the organisational capabilities, resources and requirements needed to work safely on a construction site. The legal basis is Art. 90 of D.Lgs. 81/2008, together with Annex XVII.
If you are the client or RUP, within 24–48 hours you should already have:
- an up-to-date company registration extract for the appointed contractor
- a valid DURC
- a self-certification of the DVR or a complete risk assessment document
- workers’ training certificates and, where required, a points-based licence or SOA certification
If even one document is missing, the practical rule is simple: suspend the award until the documentation is complete. This is not bureaucracy for its own sake: it is the first barrier against accidents and disputes.
Key points
Verifying technical and professional suitability requires joint checking of formal documents (DURC, DVR, points-based licence or SOA) and actual operational capability, with continuous monitoring throughout the contract.
| Point | Details |
|---|---|
| Suspend without minimum documents | A company registration extract, DURC and DVR or self-certification are the basic requirements before any award. |
| Check substance as well | Check the actual workforce, experience on similar work and consistency with the site safety plan. |
| Respect the chain of responsibility | The RUP verifies the appointed contractor, the appointed contractor verifies each subcontractor, and no step may be skipped. |
| Monitor during execution | The DURC expires every 120 days: plan periodic rechecks, not just the initial verification. |
| Digitise document management | Platforms such as Edil-up centralise deadlines and communications, reducing the risk of oversights. |

Verification of technical and professional suitability under 81/08: the rules that matter
Article 90, paragraph 9, of D.Lgs. 81/2008 requires the client or works manager to verify technical and professional suitability in accordance with Annex XVII. This provision remains the central pillar for any public or private construction site.
The framework has expanded in recent years. The points-based licence, introduced as an enabling requirement for operating on construction sites, must be checked together with, or instead of, SOA certification when the latter is not required by the type of work. For public contracts, D.Lgs. 36/2023 rewrote Article 119 on subcontracting: there are no longer general fixed quantitative limits, but the contracting authority may justify specific limits, and 49.99% remains a practical reference for the prevailing category.
| Reference | What it governs |
|---|---|
| Art. 90 D.Lgs. 81/2008 | Client/RUP obligation to verify technical and professional suitability |
| Annex XVII | List of minimum documents to request from companies and self-employed workers |
| D.Lgs. 36/2023, Art. 119 | New rules on subcontracting in public contracts |
| Points-based licence | Enabling requirement for operating on a construction site |
For private construction contracts, subcontracting rules are less strict than in the public sector, but the obligation to carry out the ITP verification remains identical: the authorisation procedure changes, not the obligation to check the supply chain.
What to check beyond compliant documents
A common mistake is to think that collecting the right paperwork means the verification has been completed. It does not. The law expressly distinguishes a formal part, namely document checking, from a substantive part, namely the actual assessment of the company’s operational capability.
The mandatory formal documents remain the starting point:
- registration with the Chamber of Commerce, with a corporate purpose consistent with the work
- a valid DURC
- the company DVR or self-certification for self-employed workers
- a list of PPE supplied to workers
- up-to-date safety training certificates
The substantive part is often skipped, but it is what really matters when an accident occurs: experience with work of similar type and complexity, the average annual workforce actually available, own equipment and vehicles, and the history of accidents or outcomes of previous inspections.
A tip: always compare the site safety plan and schedule with the resources declared by the company. If a company promises ten workers on a site but its DVR describes three permanent workers, that discrepancy must be clarified before signing, not afterwards.
Many clients confuse simply collecting documentation with a genuine suitability assessment: information gaps along the RUP, appointed contractor and subcontractor chain remain one of the most frequent causes of disputes after an accident.
How the procedure works, step by step
The technical and professional suitability verification consists of three distinct stages, each with specific actions.
During the pre-contract stage:
- request the company registration extract, DURC, DVR or self-certification, and points-based licence or SOA
- assess whether requirements beyond the legal minimum are needed, based on the complexity of the project
- check consistency between the declared workforce and the volume of work to be carried out
During the contract stage, include clauses requiring the company to update the DURC during execution, promptly report workforce changes and comply with the agreed site safety plan. For subcontracting, clearly define the authorisation procedures and the documents required for the application, following the forms made available by local authorities for substitute declarations.
During the operational stage:
- record every non-conformity identified during site inspections
- set a short deadline for rectification
- suspend the relevant company’s work if the deficiency concerns safety
Which documents to request and where to find templates
Annex XVII sets out a precise list of minimum documents to request. For companies: CCIAA registration with a consistent activity, DURC, DVR or risk self-assessment declaration, a list of personal protective equipment supplied to workers, and certificates of specific safety training. Similar requirements apply to self-employed workers, with the addition of medical certificates where required by the role.
Self-certification is permitted when the site is estimated at under 200 worker-days: in these cases, a substitute declaration confirming possession of the requirements is sufficient, accompanied by a company registration extract and DURC. A short self-certification template must always include: the company’s identifying details, a declaration that the DVR is held or standardised procedures are applied, the number of workers employed and a reference to the validity of the attached DURC. Updated templates are generally available on the websites of local authorities or the relevant professional bodies.
Who must carry out the verification and who is responsible
Responsibility for the technical and professional suitability verification follows a cascading logic, and this is where most disputes arise. The RUP or client verifies the appointed contractor; the appointed contractor must in turn verify every subcontractor using the same criteria applied to it; finally, the employer verifies self-employed workers operating directly on the site.
Skipping one link in this chain exposes the parties to joint and several liability in the event of an accident, and recent case law has repeatedly considered cases of abnormally low bids and limits of remedial assistance connected precisely with superficial checks on subcontractors.
- the RUP is responsible if the appointed contractor was not verified
- the appointed contractor is responsible if its subcontractors were not verified
- the employer is responsible for self-employed workers under its direction
Under Title IV of D.Lgs. 81/08, responsibilities are layered: cascading verification is often overlooked, but it creates direct responsibility for the appointed contractor when it is not carried out correctly.
How to remain compliant throughout the construction project
Technical and professional suitability is not a one-time achievement. The DURC expires, a disqualification measure may arise, and the workforce declared at the start may change radically halfway through the work. A company that was suitable at the tender stage may lose its requirements during execution, and this is precisely the transition that general guides tend to overlook.
The correct practice involves a schedule of rechecks, not just the initial verification: renewal of the DURC every 120 days, periodic checks for any disqualification measures, and updates to the points-based licence.
A tip: keep a register of document deadlines with automatic notifications. A reminder that alerts you ten days before the DURC expires costs far less than a work stoppage decided during execution.
- set review deadlines for every document with limited validity
- use a digital platform to centralise communications with the appointed contractor and subcontractors
- record every periodic verification as documentary evidence in case of disputes
A reflection on what distinguishes a genuine verification from a formal requirement
The difference between a safe construction site and one exposed to disputes often lies not in the documents collected, but in the time spent genuinely reading them. Treating ITP verification as an ongoing management process rather than a box to tick is what separates a diligent client from one who is merely formally compliant.
A platform that keeps deadlines and documents under control
Manually managing DURC deadlines, self-certifications and communications with dozens of different subcontractors is where most delays and oversights really begin. Edil-up centralises construction-site document management in one place, with reminders for critical deadlines and a traceable register of checks carried out on every company involved.
The platform does not replace the legal responsibilities of the RUP or client, which remain with the person signing the award: it is an operational tool that reduces the risk of losing sight of a deadline among dozens of open files. If you manage several sites at once and want to see how Edil-up’s document monitoring works, you can review the available plans and assess which one suits the volume of your projects.
