A construtibilidade no processo de projeto paramétrico colaborativo

Abstract

The recent introduction of parametric modeling tools to the design process has offered to architects the opportunity to experiment unprecedent geometrical shapes. But along with this freedom, comes the difficulty to get the building shape materialization, which is usually neglected in the early design stages. This difficulty of thinking the materialization since the beginning can led to decharacterizations of the initial design in subsequent phases, causing significant changes especially during the construction phase, or making the design unfeasible to construction. This context demands, in the design process, a high integration between structure, material, fabrication and construction. This complexity requires, according to the literature, a group working collaboratively, especially combining the expertise of architects and civil engineers. This scenario drove us to the following research question: “How constructibility affects the parametric design process?”. Our hypothesis is that the awareness of constructability, when prioritized since the early design stages by collaborative teams, contributes to parametric design, making construction aspects more integrated to the modeling and consequently facilitates the materialization of the building. The study object comprises the relations between constructibility and parametric design process. This research aims to analyze how constructibility aspects, considered by a collaborative team, affects the parametric design process. The research method is based on the constructive research, divided in problem comprehension (phase I), proposition of a solution (phase II) and validation (phase III). The phase I, of comprehension, is composed by the following stages: theoretical-conceptual and empirical basis and design experiments. The phase II, of proposition, will be destinated to the indication of methodological guidelines, while the phase III, will be the Validation of the methodological guidelines by experts in the field of Parametric Design. The main result confirmed the hypothesis in the analyzed cases, attesting that the prioritization of constructability leads to a more systematic and fluid parametric design process, through the incorporation of constructive aspects to the parametric model. We expect to contribute to the CAAD (Computer Aided Architectural Design) field with a discussion on how constructibility affects the parametric design process and with the proposition of methodological guidelines to a parametric design process focused on constructability.
