On-site surveys and acceptance testing

The “On-site Surveys and Acceptance Testing” sector aims to provide on-site assistance to Designers, Project Managers and Inspectors in order to make use of their knowledge of structures under renovation or supply test data for acceptance testing of a brand new construction.
With the recent D.M. n. 18 of 03/01/2022, Istituto Giordano is authorized by the Ministry of Sustainable Infrastructures and Mobility, to operate in accordance with art. 59 paragraph 2 c-bis of the Presidential Decree n. 380/2001 (laboratories for tests and controls on building materials on existing structures and buildings) pursuant to Circular 633/ STC of 03/12/2019.

Our highly-skilled staff possess Non-Destructive Testing Level 3 Certification and can assist those working in the sector by identifying the optimum solution for each individual project and suggesting the survey programme.

Using the experience and knowledge acquired after almost thirty years in the business, we carry out static and dynamic load testing of floors, bridges and viaducts, load testing of piles and micropiles, destructive and non-destructive testing of plain, reinforced and prestressed concrete constructions, masonry and structural metalwork.
