Reuse of cut concrete slabs in new buildings for circular ultra-low-carbon floor designs

Numa Joy Bertola, Célia Marine Küpfer, Corentin Jean Dominique Fivet

The study explores an original idea that responds to the urgent need to reduce the detrimental environmental impacts of load-bearing floor construction in new buildings by reusing saw-cut reinforced concrete (RC) pieces salvaged from soon-to-be demolished ...

How Gained Experience Influences Perceived Levers and Barriers of Reuse Practices: Learning from North Americans

Maléna Bastien Masse, Corentin Jean Dominique Fivet, Barbara Ludivine Justine Lambec

This study delves into how the perception of levers and barriers for building element reuse evolves over time as individuals and practices gain experience on this topic. Three periods of business development are compared: the genesis of practice; the curre ...

Structural component reuse of precast and cast-in-place reinforced concrete in architecture since the late 1960s in Europe

Célia Marine Küpfer, Corentin Jean Dominique Fivet

The reuse of concrete pieces salvaged from structures undergoing transformation or demolition into new architectural projects has gained a sudden and visible interest over the past five years. However, the practice of reusing concrete pieces in new structu ...

A concrete answer for circular construction: three prototypes reusing saw-cut elements

Maléna Bastien Masse, Célia Marine Küpfer, Corentin Jean Dominique Fivet

Existing concrete buildings should be retained for as long as possible to reduce the environmental burden of demolition and new construction. However, when urban pressure makes demolition unavoidable, salvaging and reusing concrete elements elsewhere in ne ...

From soon-to-be demolished mushroom column slabs to reused reinforced concrete saw-cut assemblies: the case of the rebuiLT pavilion

Maléna Bastien Masse, Célia Marine Küpfer, Maxence Grangeot, Corentin Jean Dominique Fivet

The piecewise reuse of soon-to-be-demolished cast-in-place reinforced concrete (RC) structures in new structural projects poses new design challenges. Unlike the disassembly of prefabricated structures guided by existing connections, deconstructing monolit ...

RE:SLAB — a load bearing system for open-ended component reuse in building structures

Dario Redaelli, Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting, Alex-Manuel Muresan, Edisson Xavier Estrella Arcos

The construction industry plays a major role in the high levels of greenhouse gas emissions, resource consumption, and waste generation observed nowadays. Key to the circular economy, structural component reuse arises as a promising solution to divert cons ...

Reading the existing: What discarded materials bring to the project

Célia Marine Küpfer, Maxence Grangeot, Corentin Jean Dominique Fivet, Barbara Ludivine Justine Lambec

Buildings are being demolished sooner and sooner after their construction. Regrettably this trend shows no signs of being reversed anytime soon. Demolition activities are driven today by real estate developments fueled by investment logics and rapidly chan ...

Multiscale Spatiotemporal Characterization of Embodied Environmental Performance of Building Structures in Geneva from 1850 to 2018

Corentin Jean Dominique Fivet, Catherine Elvire L. De Wolf, Serena Vanbutsele

Load-bearing systems in buildings, significant in material use and embodied greenhouse gas emissions (EGHGE), have lacked detailed analysis on their environmental and functional relationships over time and space. This study evaluates the environmental impa ...

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 ...

Computational conceptual design — typological exploration of spatial truss systems through optimization

Corentin Jean Dominique Fivet, Jonas Warmuth, Pierluigi D'Acunto

Exploring a wide range of design options is crucial for every sound conceptual design process. In the conventional structural design workflow, optimization techniques are generally employed to generate well-performing design options. However, focusing only ...

Reuse of concrete components in new construction projects: Critical review of 77 circular precedents

Maléna Bastien Masse, Célia Marine Küpfer, Corentin Jean Dominique Fivet

Extracting pieces of concrete from obsolete buildings and reusing them, as is, in new assemblies is today rarely considered a strategy for improving the sustainability of the construction sector. By delaying the crushing of concrete into aggregates and avo ...

A Reuse-Ready Timber Slab-and-Column System for Modular Building Structures

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting, Alex-Manuel Muresan, Jonas Warmuth, Edisson Xavier Estrella Arcos

The construction industry is a significant contributor to resource consumption and waste generation. To address this issue, component reuse has been proposed as a way to prevent valuable building elements from being discarded and avoid producing new ones. ...

Reuse of Load-Bearing Timber Elements - Case Study of a Lookout Tower in Lausanne, Switzerland

Julius Natterer, Benoît Pascal Kälin, Corentin Jean Dominique Fivet, Jonas Warmuth, Edisson Xavier Estrella Arcos

The construction industry is jeopardizing Earth’s environment; current mitigation efforts do not suffice; and additional sustainable strategies are required. One such strategy consists of reusing structural building elements over multiple service lives. In ...

Low-tech methods for the reuse of reinforced concrete structural elements

Maléna Bastien Masse, Julie Rachel Devènes, Corentin Jean Dominique Fivet, Nicole Widmer

Most of existing buildings are made of concrete, new buildings are being built with it and others are demolished when still in good structural condition. This drives increased demands for raw materials, greenhouse gas emissions, and an accumulation of demo ...

Panorama of approaches to reuse concrete pieces: identification and critical comparison

Célia Marine Küpfer, Corentin Jean Dominique Fivet

Practices that reuse concrete pieces in new building or infrastructure projects are currently diversifying as concrete reuse gains more and more relevance for sustainability. The present research provides a yet missing identification of the main approaches ...

Structural topology exploration through policy-based generation of equilibrium representations

Corentin Jean Dominique Fivet, Ioannis Mirtsopoulos

Mainstream approaches to design spatial architectural forms that are structurally relevant consist either in adapting well-known and catalogued conventional types or in searching for close-to-optimum solutions of well-defined problems. Few means exist to e ...

Design of New Low-Carbon Floor Systems by Reusing Cut Cast-in-Place Concrete Pieces

Numa Joy Bertola, Célia Marine Küpfer, Corentin Jean Dominique Fivet

As floors typically account for the largest share of a building embodied carbon footprint, new strategies to build low-carbon floors must be developed and implemented. Among these strategies, the reuse of existing components is a promising circular approac ...
