Building D, SYMBIOSIS District, Milan

Part of the newborn Covivio Symbiosis district, it is a building complex mainly used for offices that represents a new step in the redevelopment of the urban area.

It is composed of two units, for a total of around 20,000 square meters.

The first unit is spread over four floors, including mezzanine levels, double-high spaces and the roof structure, with the top floors cantilevering over via Orobia and housing an elevated garden.

The second unit with nine floors including the roof, has large spaces for offices and commercial premises on the ground floor.

The foundations consist of a continuous raft 25 cm deep with drops below the columns (50-180 cm), the reinforced concrete cores (100-180 cm) and the supports of the transfer elements of the office building (200 cm).

All the vertical and horizontal elevated structures are in reinforced concrete with the exception of some limited areas (transfer areas and large spans coverings) where steel sections were used.

In detail, the cover of the auditorium area is supported by steel beams to allow for a wide span without intermediate elements.

Starting from the second floor within the nine-storey high unit, the office building is supported by steel transfer elements only (deep beams with plates > 40mm thick) in turn bearing on steel Y shaped elements with square section arms ( size 1.4x1.4 m), by reinforced concrete walls and finally by steel columns.

Only the walls of the stair / lift cores and some columns on the floor edge are extended to the basement, while the remaining elements used for the support of the vertical loads (columns) are interrupted between the second and first floor.
