Beginning with the notion of programmed joints paired with digitally produced custom reinforcing, the folded tilt- up method for constructing and structuring buildings was tested using various scales and materials. A redux of the traditional tilt-up precast method, this construction logic utilizes digital tools to “program” joints with specific angles into flat castings, which are then folded into self-supporting forms, which balance compressive stresses with tensile elements along the outer edges. Smaller castings in hydrocal and acrylic preceded larger hydrocal and concrete castings at furniture scale. Finally, the idea was tested at habitable scale, substituting light-weight hollow core wood surfaces for cast material because of size and weight constraints. Folded tilt-up enables complexity of form while maintaining efficiencies in construction.
