Growing dissemination of digital fabrication technologies coupled with a renewed interest in wood as a construction material have led to a resurgence of research into integral wood joints. Recent research on digitally fabricated wood joints has focused primarily on robotic or on CNC router produced snap-fit or tab-and-slot joints. These types of joints have several problems in sheathing to structure connections. The present paper reports on research into design and fabrication of T-slot joints that allow hidden back-face connections which are disassemble-able.It is part of an ongoing research whose aim is to develop disassemble-able and mass customizable construction system of partition walls for building renovation.

O referido paradigma é particularmente adequado à realidade da reabilitação de edifícios construídos com técnicas tradicionais, um corpo diversificado em que as intervenções são por natureza cirúrgicas e singulares, e em que os tabiques desempenham um papel importante na intervenção. O aglomerado negro de cortiça e o OSB (Oriented Strand Board), materiais naturais e renováveis, podem ter um papel central num sistema material que responda a este contexto. Cork re-Wall é um sistema construtivo parametricamente modelado, constituído por estrutura de madeira e placas compostas, de aglomerado negro de cortiça e contraplacado, e um processo digital file-to-factory que permite gerar soluções personalizadas de alta qualidade para contextos de projecto diversos. PALAVRAS-CHAVE:Cortiça; Estrutura de Madeira; Fabricação Digital; Reabilitação; Desenho Paramétrico.ABSTRACT: Developments in computational design methods and their integration with digital fabrication processes enable us to envisage a customized fabrication paradigm. This paradigm is particularly suited to renovation of old buildings built with traditional construction techniques, a diversified corpus in which interventions are surgical and unique, and where partition walls play an important role. Insulation Cork Board and OSB, natural and renewable materials, can have an important role in a material system that responds to this context. Cork re-Wall is a parametrically modelled construction system and a file-to-factory digital process to generate high quality custom solutions to respond to diverse renovation design challenges.

In the last few years, building renovation has gained an unprecedented relevance in Portugal, yet it is an asymmetric and urban phenomenon for the study of which, in space and in time, traditional statistic tools have limitations. Using computational tools, it is possible to generate maps that correlate building permits georeferenced data and their processing time. Using Lisbon City Hall database of planning applications and georeferenced vector information, two approaches are developed to represent the internal dynamic of renewal of the city between 2010 and 2016. These maps can be useful to improve the accessibility of planning information to citizens.
