Upscaling them to architectural scale, however, remains challenging particularly due to insufficient structural stability and the required manufacturing processes. The necessity of a formwork in the growing process often restricts designs to simple shapes, or requires costly formwork, which limits design flexibility. In preliminary research, the authors introduced 3D wood veneer lattices into MBCs as reinforcement, similar to steel reinforcement in concrete, to provide increased strength and scaffolding. This research combines robotic additive manufacturing of 3D wood lattices with a natural fibre textile, to act as a stay-in-place formwork for planar and curved architectural components. The combined lattice and textile serve as a support structure, eliminating the need for formwork and providing the required structural performance. As MBCs are often subject to large manufacturing tolerances, the fabrication steps that influence accuracy are analysed. Therefore, two prototypes of the same design are compared: one using a temporary formwork, and the other, a stay-in-place formwork. Results show that the temporary formwork provides precise shaping during growth, while the stay-in-place approach, incorporating natural fibre textiles, allows a more organic shape development. The methods are assessed via 3D scanning to compare the physical outcomes against the digital designs, highlighting trade-offs and limitations. This study contributes to sustainable biomaterials research by offering insights into the accuracy and feasibility of these approaches for future construction elements with MBCs.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-025-00134-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research refers to the methodology <i>Renovation through Design for Adaptability/Flexibility/Change</i> to analyze and enhance existing buildings, with particular emphasis on façade systems and spatial concepts. The research applies to the case study of the Panzano residential District (1907–1927), a historic workers’ village associated with the Monfalcone shipyards, comprising of over 600 dwellings. This district exemplifies the challenge of balancing the general requirements for adapting dwelling units to contemporary needs, providing additional spaces, and mitigating energy impacts while preserving the historical value of the built heritage of a 20th -century company town. In the research approach, technology should become an integral component of the architectural design process, focusing on façade systems as a key point. These interventions aim to enhance environmental comfort, to ensure the transformability of interior spaces, and to foster inclusive interactions between individuals and their environment, while maintaining compatibility with the principles of heritage preservation. The developed methodology contributes to defining effective approaches for renovating existing buildings, while addressing both the technological and social aspects of sustainability.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-025-00131-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aims to investigate the factors that define and influence SC in the New Zealand construction sector. This goal was achieved through a modified Delphi study conducted in two rounds to gather experts’ views and reach a consensus. Data collection included in-depth interviews and survey questionnaires. A total of 32 experienced construction safety professionals participated in the first round, and 26 of them continued in the second round. Data were analyzed using Thematic Analysis and Relative Importance Index (RII). The main findings are twofold. First, they indicate the need for a holistic definition of SC incorporating its various defining factors. Second, they indicate that the top-ranked influencing factors are ‘Level of Leadership Commitment,’ followed by ‘Level of Experience and Mindset,’ and ‘Level of Communication.’ Furthermore, the results show the dual nature of these influencing factors, as they can either facilitate or hinder SC depending on whether their level is low or high.

Integrating circularity into full-scale Design/Build prototypes helps students connect sustainable design theory with practice and application of concepts. This paper examines the gap between circular design intentions and real-world barriers, focusing on DfC with wood in two educational projects. The first, in Belgium, follows a “design from reuse” approach using short-length reclaimed sawn-timber to create a small-scale canopy structure. The second, in the USA, adopts a “design for reuse” approach, using plywood to develop a reusable kit-of-parts. In the analyzed cases, the non-standard nature of DfC requires a holistic life-cycle perspective, presenting challenges in material sourcing and quality assessment, significant variability in sizes and condition, and uncertainty regarding mechanical properties. Furthermore, utilizing frequently smaller reclaimed timber elements increases the number of connections, requiring original solutions. These issues complicate architectural design, structural calculation, and permitting and influenced the design and construction in both cases. An analysis of successful DfC cases shows parallels with lessons learned, identifying common barriers and suggesting solutions. Using reclaimed wood for structural purposes requires thorough planning for transportation, storage, regrading, and reprocessing. Design flexibility is critical to accommodate dimensional variability and mechanical downgrading. When designing for reuse, adequate fabrication tolerances and well-designed connections are key to ensuring structural integrity and easy disassembly. Increased educational projects can build a robust knowledge base, leading to currently lacking standardized procedures and streamlining DfC practices in architecture, engineering, and construction industries. This paper enhances understanding of DfC with wood and Design/Build education by identifying barriers, opportunities, and methods to improve education and training, aiming for a more sustainable built environment.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143396547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Buildings designed for robotic construction may be different than traditional buildings, and computation can help reveal these differences. In response, the goal of this research is to assess the challenges, opportunities, and potential of robotic construction to be incorporated into early-stage design exploration and multi-objective optimization. It evaluates robotic capabilities for performing construction tasks, determines how designs with varying structural systems can leverage robotic constructability assessment, and shows which tasks and design types offer good venues for evaluating construction metrics during design optimization. The first part reviews literature in design, fabrication, and construction, covering design-based robotic research in which robots are replacing traditionally human tasks in standard construction, as well as research in which a custom design can only be built with a novel construction approach. The role of robots in construction is then examined through a task-based review, which maps existing robots and their capabilities to potential subtasks during sequential construction phases, from initial offsite preparation to completion. Finally, a case study built on insights from the literature review introduces an initial construction metric tied to cumulative discrete material delivery time. This metric helps distinguish between high and low-quality designs in terms of constructability, showcasing how considering robotics can enhance early-stage design assessment. A trade-off between embodied carbon and a robotic construction score emerged in the design options, with the number of elements affecting both factors. The case study suggests that adjustments to the building massing can lower embodied carbon without negatively impacting the construction score. Similar relationships could be uncovered by incorporating the objectives and constraints identified in this paper in future optimization workflows.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By leveraging funicular forms such as thin concrete shells, a materially and carbon-efficient alternative to bending-active flooring systems can be attained. In addition, through segmentation and the use of dry jointed interfaces, a segmented concrete shell allows for ease of disassembly compatible with circular economy principles for the built environment. This paper presents a novel segmented concrete shell flooring system that leverages the symmetry of revolution of the classical fan vault form to facilitate future design flexibility through increased reconfigurability. The design and form-finding of the segmented fan concrete shell are detailed through the use of an evolutionary algorithm and finite element analysis. Quarter-scale prototypes were digitally fabricated using a robotic concrete spraying process which were then assembled and tested to assess its structural potential, evaluate the limitations, and identify areas of future work. An embodied carbon analysis demonstrates that the system provides a mass and embodied carbon saving compared to conventional flooring systems while adding approximately a 20% embodied carbon premium over a comparable non-reconfigurable segmented shell flooring system. Rephrased, the proposed system provides a positive embodied carbon saving if enabling design flexibility through reconfiguration increases the life-span of the system by at least 20%. Through this work, it is shown that a segmented fan concrete shell presents a viable lightweight and carbon-efficient flooring system which has the potential to become a sustainable alternative that enables disassembly, reuse, and even reconfigurability for circular construction provided further research and development to address its current limitations for adoption in industry practices.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-025-00126-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
