[3] By 1967, improvements were made and Bini demonstrated the prototype - a 12-meter dome constructed in a span of few hours - at the Columbia University in New York.
[3][9] This particular construction and those built afterward required helical “springs” reinforced with steel bars to ensure a geometrically controlled inflation, allowing for an even distribution of wet concrete.
[3] From 1970 to 1990, Bini constructed thousands of Binishells around the world, serving different purposes such as homes, schools, sports facilities, and industrial storage units.
[4] The Binishell technology is also considered a potential solution to housing problems for displaced people, refugees, and evacuees, particularly in areas consistently damaged by disasters.
[12] Bini has offered the technology royalty-free to governments and non-governmental organizations (NGOs) that intend to build shelters for these people.
Bini, together with architect David Dimitric, also designed Shimizu Corporation's Mega-City Pyramid project,[14] a proposed vertical city over Tokyo Bay built by robots.
[13] The architect has participated in initiatives advancing shell-concrete technology such the colloquium at the University of Stuttgart which focused on air and pneumatic structures.
