Cosiam Cosiam is the result of our professional and educational experiences as builders since three generations starting in 1928, with particular expertise, in the building, environment and restoration sector.

Founded in 1996 by the current associates Greco Rocco and Presti Vincenza Rita, Cosiam is now a company that maintains its own core business in the building sector thanks to the unification of important business.

Nowadays Cosiam deals with the promotion of big projects for urban transformations, the realization of concession or contract infrastructures, as well as the management of important manufacturing activities, with the same commitment and the same passion of a century ago.

Research and Development

Gretec is an innovative start-up intended specifically to consolidate the axis R & D of Cosiam.

A team of young students that are now operating on technology applied to the field of construction, are now exploring the world market to search for the most intelligent materials and provide an essential connection between the company and the world of research.

Sustainability and Technology. A common denominator that indissolubly links the two realities.

Social responsibility

We believe that doing business means creating value. What is more valuable than the smile of a child?

Cosiam is the main sponsor of the Macchitella Gela football association, born from the idea of a group of young catholics, which for more than five years have encouraged the growth. Soccer school and academies are some of the most important youth sectors of Sicilian Football.
