Despite recent advances in the production of research-based knowledge, the professional practices lack of a consistent and permanent technology adoption scheme and remain as a very resilient and fragmented industry. This work is a part of an ongoing research project developing guidelines for improving both physical and virtual modeling processes within an architectural design context. Here, we present a customizable model of a space layout explorer. The implementation of the user-driven solution-finding process is based on constraint technology embedded in Autodesk’s Revit® 2011 macros tools, commonly used in the professional practice. The aim of this work is to demonstrate a practical use of a small constraint-based system on software of widespread use. Even though there is still a lack of building information, the model has already several applications in the definition a floor plan layout and in the comparison of several instances of the design solution in the 3D user view. User-driven modifications are not made directly through the 3D model, but through different explicit text tags that describe each parameter on 2D views -although a real time 3D visualization of the model is also available-. The main findings are discussed as guidelines for further research on the end-user involvement on a ‘creative mass customization’ scheme. Also, the implementation of visual aids such as text tags during the customization process can bridge some technical obstacles for the development of interfaces for constraint-based mass customization systems. Before the final discussion, some limitations on the use of this model are described.

As the current digitally-mediated architectural practice evolves, architectural models, regardless of their expressiveness or type, are a way to craft the interaction between the designer and the designed object. Models become artefacts that engage on a continuous interaction with the designer via different media, interpretation and knowledge retrieval schemes, organizational flows and tools. These interactions have recently been facilitated by the use of physical and digital production and analysis methods. In this report, we introduce a novel understanding of the relationships between physical and digital modelling techniques. We propose an updated framework that allocates these relationships into four categories: directed production, non-directed production, dual modelling, and mixed modelling. A review of different modelling classifications and frameworks is presented and exemplary case studies from the design domain are introduced for each category.

This paper is a part of a research in information management in construction and design, and analyses the current data flow in construction site in order to elicit which tasks are keen to be supported by mixed reality-based tools, in order to extend the information contained in digital models (BIM) to the construction site. Different existing systems have been analysed and finally two implementation solutions are proposed to improve communication between the technical office and the on-site construction manager; both are critically analysed and finally further work recommendations are made.

Located 600 km (~370 mi) away from the continent, this town is not just the home of several endemic species, but is also located next to a National Protected Area and UNESCO Biosphere Reserve. Within this context, the design problem consisted on the development of a component-based strategy and prefabrication requirements, and to reduce to the minimum the implied logistics and environmental impacts of the new buildings. With a Studio of 23 final year students and the support of the Architecture Firms Association, 11 projects were developed using digital tools such as visual programming and digital fabrication. Finally, technical documentation was produced and delivered to the local and government authorities.

Para atingir tal otimização, um grupo heterogêneo de atividades de fabricação são estudados de acordo com o Registro de Classificações UN 2007, e sua aplicação à indústria chilena é avaliada.

For achieving that optimization, a heterogeneous group of manufacturing activities are studied according to the UN Classifications Registry (UN 2007), and their application in the chilean industry is evaluated. The explored model has been formulated according to Senn’s (1992) method of prototype design, and the method of information systems development based on its life-cycle. Finally, by using a Visual Programming Language (VPL) interface, the model is applied for the formulation of the design problem of a customized constructive component. In this case, the component is a sanitary services pack. The proposal includes an experimental Graphic-User Interface (GUI), where each client configures the constructive components according to his particular requirements.
