3DCP prefabrication for complex topographical contexts: a case study of rocky pontoons

Abstract

This article explores the potential offered by 3D Concrete Printing (3DCP) through the analysis of a practical application case: the qualification of rocky pontoons in marginal areas with spaces for recreational use and protectors of marine biodiversity. The purpose of the work is centred on the production of a set of platforms, divided into prefabricated concrete modules, which fit perfectly into the complex geometry of marine rockfills, generating new uses for these areas of difficult access and appropriation. The paper focuses on questions related to the manufacture of a prototype, accompanying the process from the design phase to its execution. For this, a methodological division into five sections is followed: (1) a literature review with a view to production and application in a real context; (2) the design of the architectural object; (3) the preparation the object for printing; (4) the production in laboratory environment; and (5) assembly and fastening on site. In conclusion, the work presented demonstrates a case of application in a real context where 3DCP technology allows generating more efficient and sustainable solutions to design and build architectural elements adapted to highly complex contexts, such as rocky pontoons. We anticipate that the results of this study will provide an impetus for further exploration and utilization of technology in other intricate contexts.
