Working following the logic of quality and professional competence has always been fundamental for Belli S.r.l.

The positive results obtained represent the greatest incentive to further improve the standards of quality and efficiency achieved so far.

Quality improvement has included the following:
  • ISO 9001:2008 certification, which is mainly interpreted as a “formalisation” of an internal system already able to provide the quality standards required by the applicable standards;
  • certificate of qualification for carrying out public works, issued by Bentley SOA from February 2001 for the following categories and classifications
    - OG1 VI, OG 11 V, OS3 II, OS28 IV, OS30 III;
  • certification for carrying out work in airport environments (ENAV)
