Martifer Metallic Constructions is responsible for the design and construction of the stadium's roof (metallic structure and cladding), a refurbishment that will increase the stadium's capacity from 25,000 to 40,000 seats.

The solution developed by Martifer for the roof passes through a set of 52 cantilever trusses, with about 40 meters, connected from the outside to the new reinforced concrete pillars through arms, with about 10 meters and tension rods, with about 22 metres.

The total coverage area is about 25,000 sqm.
