Completed projects
A residential project designed to turn construction quality into real well-being:
bright spaces, refined finishes, and design solutions focused on comfort, efficiency, and durability
Construction of a new industrial complex in the
Castel San Giorgio area
Extraordinary maintenance works
on the Borgoforte Bridge
Public spaces were redeveloped as community gathering points: seating, planters, street furniture elements, and new arrangements for rest areas transformed squares and panoramic lookouts into true open-air “urban living rooms.” Attention to materials and details, in continuity with local tradition, made it possible to integrate the new project into the historic fabric, enhancing views, perspectives, and existing architecture.

km built
The construction of the viaduct on the Via Langhirano roundabout was a highly complex civil engineering intervention carried out while maintaining heavy traffic throughout all construction phases. The curved cast‑in‑place viaduct, without intermediate joints, required rigorous execution planning, with detailed work phases and maximum attention to safety and timelines. The schedule was met thanks to the team’s expertise, constant support from site supervision, and effective coordination with the client.
