Pier Luigi Nervi (1891-1979)

Praised both as architect and engineer, Pier Luigi Nervi greatly affected the 20th century by exploring the use of reinforced concrete in a variety of inventive structural projects.

The Brain of an Engineer, the Heart of an Architect.

Pier Luigi Nervi was born in 1981 in Sondrio, Italy. He studied Civil Engineering at the University of Bologna, immediately showing an incredible artistic sensibility. Despite his natural talent, he never studied architecture at a university, but this fact never seemed to hinder his architecture. After the graduation, Nervi co-founded the building firm Nervi and Nebbiosi, which would later become Nervi and Bartoli. He became very popular because of the ability to keep the cost down in creating ground-breaking designs. This was possible due to the adoption of reinforced concrete, which represented his trademark.

The engineer garnered major public attention with the project for the Stadio Artemio Franchi, in Florence, with its unmistakable cantilevered roof and winding stairs. Nervi also built a series of airplane hangars for the Italian Royal Air Force, now destroyed. These works established his reputation as a master of architecture and engineering. Other masterpieces are the Torino Esposizioni, the UNESCO Headquarters in Paris, the Pirelli Tower, the Palazzetto dello Sport.

Usability and Innovation

Pier Luigi Nervi based his approach to design on intuitiveness, without ever losing sight of the functionality of the structure. His sensibility for the balance between structure and shape led him to bold design, mixed with affordable materials, such as reinforced concrete. This model had a great influence and inspired other architects all across Europe. He was driven by the desire for expressing the beauty and the ingenious implementation of this material in his works. He made broad use of prefabricated and introduced the ferrocement, a system of construction using reinforced mortar or plaster, applied over a metal “armature” and closely spaced thin steel rods such as rebar. This method was a response to international trade sanctions, because of the invasion of Ethiopia.

A True Master of Parametric Design

While nowadays parametric design is based on computer-aided technology, Nervi was a master of this design and biomimetics architecture already in his time, building beautiful, functional structures. For example, the former zoology lecture hall at the University of Freiburg was inspired by the internal geometry of bone tissue, optimized to resist external forces by creating a porous bone that efficiently maximizes its strength to weight ratio. Nervi maximized the complexity of his design by transforming and revolving simple forms; the sophistication of his geometry was never limited to the constructability of the structure. Nervi truly understood the relationship between design and construction and was able to utilize this knowledge to drive his works.

Palazzetto dello Sport

This visionary project spread all around the world the dome architecture. Palazzetto dello Sport is a mid-way between a rigorous formal taste and an enveloping aesthetic. It was designed in the 1950s by Pier Luigi Nervi and Annibale Vitellozzi as a prototype of sporting palace built with economical materials. The dome was made in prefabricated ferrocement, characterized by a smooth exterior and an embroidered inside. It was one of the first applications of the so called “Nervi System”, the typical approach of Pier Luigi Nervi to keep down costs. This structure became a symbol of the rebirth of an area formerly abandoned, proposing at the same time a new way of conceiving architecture.
