CQOP SOA — Costruttori Qualificati Opere Pubbliche

List of SOA categories

SOA categories identify the types of work for which a company is qualified. They are divided into 13 categories of general works, designated as OG, and 39 categories of specialised works, designated as OS. Each category listed on the certificate is associated with a financial classification. In the SOA system, classifications and categories work together: the category indicates the type of work, whilst the classification indicates the maximum value of work that can be carried out.
