Suitable average annual workforce as proven by a total cost of employee labour of not less than 15% of the turnover in works, of which 40% must be for construction/production staff; otherwise, a cost of permanently employed personnel not less than 10% of the turnover in works, of which 80% must refer to technical staff who hold degrees or high school diplomas.

In the case of partnerships or one-man businesses, the “INAIL (Workers’ Insurance) standard pay” may be used.

technical capabilities and technical manager Suitable technical management, the technical manager must hold a suitable educational qualification or, for classifications up to III-bis, five years’ working experience as site manager; he must meet the general prerequisites set by the law; the role of technical manager may be held by the business’s owner, its legal representative, a partner, a director, an employee or an external freelancer working under a properly registered contract.

Execution of works in the individual categories required for amounts of not less than 90% of that of the classification required.
