Riverbeds provide natural sand, which is a typical supply of fine aggregate used in concrete making. The removal of river sands has had negative effects on the ecosystem. Steel dust is a fine substance that may be used in place of fine aggregate principally because of its comparable particle sizes. This research investigates the impact of adding wasted steel dust on concrete’s mechanical behaviour by partially replacing sand in different percentages (0%, 3%, 6%, 9%, 12%, and 15%). The water-to-cement ratio of 0.45 was used in this study. Overall, 54 concrete samples were prepared, 18 cubes (150 mm × 150 mm × 150 mm) for the compressive strength test, 18 cylinders (100 mm diameter × 200 mm height) for tensile strength, and 18 prisms (100 mm depth × 100 mm width × 500 mm length). Then tests were made for all samples to observe the strength and crack behaviour of concrete. It was found that the workability of fresh concrete decreased while the density of hardened concrete increased with steel dust replacements. Also, adding steel dust to concrete generally increases strength. The optimum value was observed in concrete containing 9% steel dust in compressive and flexural strength. An optimum value is found in concrete containing 15% steel dust for tensile strength.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602247","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}

In this context, \"on-site construction\" refers to work completed on-site in off-site construction projects or on-site projects using specific construction methods. As the adoption of design for manufacturing and assembly increases, it is crucial to identify challenges associated with its implementation in various construction phases. This article aims to identify, verify, and analyze the challenges to the adoption of design for manufacturing and assembly with a focus on the on-site parts of the construction. A mixed-method approach, including a comprehensive literature review and expert interviews, was used. Data was analyzed using NVivo 14 Pro and prioritized using the mean score analysis and weighting function. The study validated 42 challenges, categorized into 9 key areas, with the top three being economic and financial, technological, and legal-contractual challenges. They formed the basis for developing a conceptual framework representing design for manufacturing and assembly-related challenges. By exploring the barriers to the adoption of this methodology in both off-site and on-site construction, this article aims to contribute to construction management knowledge and provide insights for industry professionals, researchers, and policymakers on how to overcome these challenges and enhance productivity, sustainability, and competitiveness in construction projects.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554070","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}

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.

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}
