Technicalities - 'Toyo Ito builds a concrete cloud' Russell Fortmeyer (Architectural Record 03.07)
This article describes a recent building by Toyo Ito - a crematorium in Japan. The building appears like a cloud floating above the ground but is actually an undulating concrete roof, anchored to the ground by colums that hold the structure up and hide a roof drainage system.
Fortmeyer describes how the roof was poured in five stages. Grinding machines were used between each pour to smooth the joint lines and provide a smooth surface. Concrete was poured onto a complex formwork arrangementof steel built on top of timber. A hard mix was used to prevent the concrete sliding down the slopes of the roof during pouring.
