summary 
The presented research develops methods for introducing fabrication constraints into architectural design, a process often referred to as design rationalization. In the first stage of the research, a computational method for evaluating the fabrication potential of geometries was developed. The method predicts the feasibility, material use and machining time of a geometry in relation to different fabrication techniques. It uses geometric properties to mathematically estimate these parameters without simulating the actual machining. The second stage of the research describes processes for adapting architectural designs to their fabrication technique. The evaluation method previously developed is used as a fitness criterion for a computational optimization algorithm aimed at adapting concrete façade elements to the fabrication constraints of their molds. A case study demonstrates how the optimization process succeeded in improving the feasibility of different geometries within a timeframe suitable to the architectural design process, and without significant changes to the initial design.
