Crackology's objective is to create a relationship between infrastructural flows and architectural space. We aim to move beyond traditional understanding of cellular space and continuous flows to create a new ground condition that exists between the two. Using the principles found in cracking, that of non-linear flows and the space created through applied forces, the urban proposal aims to setup a new sectional relationship to the city. The conventional urban strategy of streets and blocks segregates public from private and produces linears flows of movement that remain either horizontal or vertical. We propose to replace this with a blending strategy. By creating a thickened ground condition, which holds both "streets" and "buildings", an alternative urban dynamic is generated. Here flows are non-linear, moving between private and publics in a continuous pattern. The traditional understanding of solid and void is destabilized as pockets of public space can appear anywhere within the spatial continuum. We aim to achieve this by merging infrastructural flows with public space and private programme. In Sao Paulo the optimization of infrastructure provides the opportunity to create public spaces on the left over sites, but on our site this has led to the isolation and disuse of these public facilities. We aim to go a step further and use the infrastructure to blend public and private space, creating overlapping parks and office space. Using the voronoi algorithm and continuous surfaces we take advantage of both typologies’ strengths to create a filtering machine for flows. As cars, buses and pedestrians pass through the site, their movements create an urban massing that is fluid and differentiated both in plan and section to allow for varying programs, such as office towers, residential areas, and a bus station. The focus of our work was on the public spaces that were created between these traditional programmes to allow for the spontaneous activity that is characteristic of Sao Paulo.
