- Resumen
The present thesis work intends to explore and research how far these new tools and modeling techniques can reach, regarding the generation and control of free forms (conceptual or mass modeling) in geometries generally complex on BIM environments, including its incorporation to the work flow within the definition process of the architectural project, as well as its integration in the BIM model definition. This allows the holistic visual comprehension of all architectural and building elements of the model, resulting in greater predictability, decrease of uncertainties, and reducing loopholes and information losses.
It is also the aim of this study the control of such forms, its analysis, generative study, its geometry and those parameters from which generation and govern will be performed, in short, its optimization based on different criteria and given features, so as to obtain a greater efficiency by reducing costs and negative impacts on the environment. Forms are understood as a result of a complex synthesis and analysis process, and not just as a mere apriorism. Techniques are described to develop this kind of controls, analysis and management for the generating processes, which minimize the uncertainty factors and reduce possible deviations between the projection and its execution in all development phases of the project.
Two alternative ways for modeling provided by current modeling software on BIM environments are analyzed: parametric modeling and the more recent algorithmic modeling. The latter needs its own specific VPL visual programming language to be used. Relationships and bidirectional dialogue established between the two is also studied, as well as regarding other software for the exchange of information, such as spreadsheets, data bases and others (structures calculation, installations, energetic audits, etc.), allowing for interoperability, a property benefitted and empowered by BIM work environments.
The incorporation of these digital techniques allows not only the exploration of new modeling possibilities and complex forms generation, with the possibility of performing multiple options, simulations, checking, trials and the analysis of alternatives regarding their real behavior, that will help optimal decision making, but the optimization of the design process itself, focusing on traditional methods and projection tempos.
This technification process of architecture opens up new ways of exploration and collaboration in forms modeling, also allowing, within VPL visual programming languages, the introduction and incorporation of conventional textual programming code (Design Script, Python, C#, etc.) to be able to create new customized design tools and automate repetitive tasks, with a considerable time saving regarding other types of modeling.
Both modeling alternative ways are applied to a practical modeling case involving a very singular building such as Norman Foster's Swiss Re Tower in London, where the different forms of work, tempos, modeling strategies, objectives and dialogue bidirectional relationships and exchange of information between the two can be noticed, as well as the incorporation to the development and project gradual definition work flow.
