Learning to Assemble with Alternative Plans

Gabriel Rémi Vallat, Maryam Kamgarpour, Stefana Parascho

We present a reinforcement learning framework for constructing assemblies composed of rigid parts, which are commonly seen in many historical masonry buildings and bridges. Traditional construction methods for such structures often depend on dense scaffold ...

DiffCheck: A scan-CAD evaluation tool for digital manufacturing and assembly processes in timber construction

Yves Weinand, Julien Gamerro, Andrea Settimi, Stefana Parascho

In digital timber construction, scanning technologies and point cloud data are widely used due to the accessibility of affordable 3D sensors, photogrammetry, and userfriendly CAD tools. While typically not employed for accuracy checks in timber fabrication ...

New tectonics of concrete through rubble reuse

Maxence Grangeot, Corentin Jean Dominique Fivet, Stefana Parascho

Driven by the sustainability of the construction industry, concrete rubble is increasingly considered as a construction material rather than a waste. Analysing structures from such material through the conceptual tool of tectonics highlights a fertile grou ...

Disused Concrete, Digital Acupuncture and Reuse

Maléna Bastien Masse, Maxence Grangeot, Corentin Jean Dominique Fivet, Stefana Parascho

Crushing concrete liberated from demolished buildings to provide recycled aggregate is argued to be a sustainable way of reducing material extraction. Yet, in these high‐energy processes, large amounts of new cement is often used, negating this as a low‐ca ...

Concrete rubble as a new construction material: Panorama of applications to known structural typologies

Maxence Grangeot, Corentin Jean Dominique Fivet, Stefana Parascho

Concrete rubble is among the most wasted materials worldwide. In this paper, we present a panorama of the upcycling potential of disused concrete rubble as construction material for new low-carbon structures. We identify 15 existing structural applications ...

Upcycling concrete rubble into masonry walls: Design and assessment of two prototypes built with digitally augmented tools

Maléna Bastien Masse, Maxence Grangeot, Corentin Jean Dominique Fivet, Stefana Parascho

Concrete rubble is currently a downcycled material whose upcycling remains under-explored and complex. This paper presents an accessible upcycling strategy to design and build slender structural masonry walls made from off-the-pile large demolition concret ...

Beyond Optimization: Interaction as a Means to Resituate Digital Fabrication

Stefana Parascho

In this case study, researcher and professor Stefana Parascho proposes that interactive and improvisational robotic fabrication can be a means to counteract what she perceives to be one of digital fabrication’s more detrimental fixations: optimization. In ...

Assembly of Spaceframes in Hybrid Teams: Adaptive Digital Fabrication Workflows for Human-Robot Collaboration

Stefana Parascho

In spatial timber assemblies, a multitude of factors can lead to errors that hinder the implementation of complete automation including but not limited to inaccuracies of the robotic setup, deformations of the structures during assembly, or the natural dim ...

Evaluation date as support material for diffCheck publication icsa 2025

Yves Weinand, Julien Gamerro, Andrea Settimi, Stefana Parascho

This dataset contains the data, pipelines (in the form of .ghx files) and numerical results of the evaluation of diffCheck, an open-source scan-to-CAD comparison plugin for Rhino3D. The dataset is divided into two main compressed folders: Additive and `S ...

Rising from rubble - Leveraging existing construction tools for upcycling concrete waste into slender walls

Katrin Beyer, Maxence Grangeot, Corentin Jean Dominique Fivet, Qianqing Wang, Stefana Parascho

In this paper, we present a new method for upcycling concrete rubble waste into slender walls through the lightweight digital augmentation of mainstream construction machines. By using such method, the environmental impact of concrete construction and demo ...

Structural Concrete Rubble Arrangements - A Framework for Upcycling Demolition Waste into Slender Masonry Walls for Buildings

Katrin Beyer, Maxence Grangeot, Corentin Jean Dominique Fivet, Qianqing Wang, Stefana Parascho

Reused concrete rubble is a challenging material to design and construct with despite its potential for diverging waste from landfilling and energyintensive recycling. We propose a design to construction framework that leverages a camera and computationall ...

BamX: Rethinking Deployability in Architecture through Weaving

Mark Pauly, Yingying Ren, Tian Chen, Seiichi Eduardo Suzuki Erazo, Stefana Parascho

Deployable gridshells are a class of planar-to-spatial structures that achievea 3D curved geometry by inducing bending on a flat grid of elastic beams. However, theslender nature of these beams often conflicts with the structure’s load-bearing capacity.To ...

Constrained Form-Finding of Tension-Compression Structures using Automatic Differentiation

Stefana Parascho, Pierluigi D'Acunto

This paper proposes a computational approach to form-find pin-jointed bar structures subjected to combinations of tension and compression forces. The generated equilibrium states can meet structural and geometrical constraints via gradient-based optimizati ...

ELSEVIER SCI LTD2023

From concrete waste to walls: An investigation of reclamation and digital technologies for new load-bearing structures

Maxence Grangeot, Corentin Jean Dominique Fivet, Stefana Parascho

The research presented in this paper highlights current practices for the end-of-life of concrete and explores opportunities in using unaltered concrete rubbles from demolition for the digital construction of structural walls. Through research by iterative ...

Reinforcement learning for scaffold-free construction of spanning-structures

Gabriel Rémi Vallat, Anna Maria Maddux, Jingwen Wang, Maryam Kamgarpour, Stefana Parascho

In construction robotics, a conventional design-to-fabrication work-flow starts with designing a structure, followed by task and robotic motion planning, and ultimately, fabrication. However, this approach can prove unsuccessful, as we may only discover th ...
