We participated in all facets of design, engineering and construction of the Ridolfi staircase. Carved from Italian limestone, it features techniques such as pre-tensioning in massive bloc.
We are very proud to be the first persons to be a part of this innovation in the stone industry.
This was presented in the “Venice Biennal of Architecture” in 2006 by Luc Tamborero and Giuseppe Fallacara.
Please find a portion of the calculations, studies and the first fixing systems during the fitting of this structural work.
