Analysis
What this data actually tells you
Construction in Italy runs on a labour-cost verification system layered on top of company registration. Since DM n. 143/2021, contracts worth €70,000 or more — mandatory and generalised for construction work of any amount — require a DURC di congruità, a distinct certificate confirming that a company’s declared labour cost is coherent with minimum incidence percentages set by the relevant collective sector agreement, aimed at curbing irregular work and contractual dumping. The main contractor, not the subcontractor, is responsible for activating the site on the Edilconnect portal and requesting the attestation.
That structure creates a shared exposure: a subcontractor’s inaccurate labour-flow or site data can distort the overall site’s congruity outcome, even though the main contractor requested the check. For verification, an Italian construction counterparty’s DURC di congruità status is a real, checkable signal distinct from its SOA (Società Organismi di Attestazione) qualification — the latter confirms technical and financial capacity for public-works eligibility, the former confirms labour-cost compliance on a specific site.

Who uses Italy construction ownership data
The three checks this sector's data is most often run for.
DURC di congruità (labour-cost coherence) check
Italian construction contracts worth €70,000 or more require a DURC di congruità — a certificate confirming the labour cost a company declares matches minimum incidence percentages set by the sector’s collective agreement — filed via the Edilconnect portal by the main contractor, not the subcontractor.
Subcontractor labour-flow accuracy
Anomalies in a subcontractor’s declared labour flows and site data can affect the whole site’s overall congruity outcome, since the main contractor activates the site and requests the attestation on behalf of the full subcontracting chain.
SOA attestation and public-works eligibility
Larger public works require a company to hold SOA (Società Organismi di Attestazione) qualification, verifying its technical and financial capacity for the specific category and value of work — a separate check from ordinary company registration.
