Ghella
Founded in 1894, Ghella is a major Italian global force recognized for its excellence in the construction of large-scale public infrastructure and expertise in the use of Tunnel Boring Machines (TBMs).

Specialized in underground excavation, with five generations of long-standing tunnelling experience, we have completed over 190 tunnels, connecting more than 1,000 km of metros, railways, motorways, and hydraulic works.
We take pride in our diverse community of over 6,000 people, residing in fifteen countries, and working across four continents, primarily in Oceania, Europe, North and South America, and Southeastern Asia.

Through Ghella × Roma, the commitment to the city continues with targeted projects to support the enhancement of Rome’s cultural heritage.
