Project description

Pirelli 35 was one of the symbols of 1960s Milan, a thriving business center originally designed by Architect Melchiorre Bega. The intervention of hard retrofitting and re-composition provides its complete revitalization. Through a partial demolition, the building becomes a permeable space facing the airy and dynamic inner courtyard. This transformation is emphasized by a bridge building which connect the main structure to the new six-arising block. Collaboration between Park Associati and Snøhetta seamlessly merges architecture, landscape, and urban design to create a generous and public wise accessible building with significantly reduced environmental impact. It is set to achieve Leed Platinum, Well, Cradle To Cradle, and Wiredscore certifications.

CEAS had provided the whole design development, from sketches to final details, handling with Structural and Geotechnical choices in all phases, as well as the development of the Construction Project, giving proper advice to the Contractor both on-site and through updates of the BIM model and technical drawings.

The recent deconstruction phase started with the analysis of delicate demolition stages, which yields to optimization of the seismic retrofitting interventions, primarily focused on the structural work tailored on the existing C-Building. The results, a mix of more conventional with innovative consolidation techniques, widely encompass the project’s architectural transformation philosophy. Rise blocks, vertical and horizontal structure reinforcement, including the installation of coupling dynamic devices (Shock Transmitter Units) are just some of the engineering aspects which shaped the changing of independent structural units into a single seismic body.

The new L-Building play a significant role to challenge seismic structural efficiency, namely the Bordoni and the Bridge, the former showing its slimness by means of the slim post-tensioned concrete slabs, while the latter the lightness with the two Facades-Trusses in steelwork frame, spanning over 32 meters, supported onto four pins and twenty-four horizontal devices. These elements have been designed to create a continuous structural plane by the Bridge frame inserted along with the architectural concept.
