PARAMETRIC HERITAGE. THE DIGITAL RECONSTRUCTION OF P.L. NERVI’S PALAZZO DEL LAVORO IN THE 3DMODELLING AGE

Abstract. One of the main themes of this work is to incorporate the geometric aspects that characterize a certain type of architecture within a broader rule system, which, in the whole, generate the forms. Therefore, the solution would be to draw the reconstruction of a parametric model, through the application to a selected case study: Palazzo del Lavoro of Pier Luigi Nervi. The identification of some weaknesses of the project is important in order to digitally intervene on them, to prefigure a new life of the artifact in a virtual environment. By doing so, it will be possible to have truthful feedback in the real environment. The survey phase did not intend to reason on the architecture in its complexity, but rather on the observation of the matrices that regulate the similar geometries between them. The translation of these matrices into mathematical models, following the logic of HBIM and Algorithmic Design (AD), has allowed the creation of two different models. The first one, an informed model, characterized by a more traditional workflow, consists of building components based on design drawings of the time, aimed at graphically and quantitatively describe the entire artifact. The second one, a partial model of the only vertical component of the facade, is based on the canons of the element, and it is structured through algorithms that describe only a part of the architecture. The research wanted to deepen the interoperability of the information coming from the parametric models BIM with those generated by the algorithms.
