The origins of the Bonaria company can be traced back to the Grand Duchy of Luxembourg around 1904, when the grandfather arrived in the country and started building single-family homes. The company M. & A. Bonaria was not founded until 1958 by his sons Mario and Arthur Bonaria. It specialised in earthworks, and later extended its range of activities to include civil engineering. Since restructuring in 1993, the company has been known as Bonaria & Fils.
Today, Bonaria & Fils, based in Esch-sur-Alzette, is mainly active in the following sectors:
- Civil engineering, urban networks and roads
- Structural construction and conversion of public and private buildings
- Exterior fittings
- Selective demolition and reinforced concrete
- Remediation of polluted sites
