In the winter of 2018, a team of architects and engineers from the University of Cambridge built the world's first hyperboloid-net ice structure in Harbin, China. A prestressed hemp rope net was sprayed with a cellulose water mix to form a structural sculpture which won the International Ice and Snow Construction Competition to which it was entered. Ice structures have traditionally been constructed from blocks of ice, whereas this project used a variation of Pykrete sprayed onto a flexible formwork. This paper explores areas of ice construction that have been little researched; the spraying of rope nets, difficulties in the construction of ice nodes, and the buckling of struts during construction are discussed. The project proved the viability of sprayed net ice structures and successfully used rope formwork to pretension the ice columns in a design that was both efficient and novel.
