This study investigates how the spatial distribution of public leisure and cultural facilities affects residents' perceived accessibility in this context. Key indicators include spatial concentration, spatial equity, and diversity, analyzed using a multilevel ordinal logistic regression model—an extension of the Hierarchical Linear Model (HLM). The findings reveal that higher spatial concentration is significantly associated with greater perceived accessibility. Notably, several cities in Jeollanam-do demonstrate high accessibility perceptions despite a limited number of facilities, due to their strategic placement within core neighborhood zones. Conversely, spatial equity and diversity showed no significant effect. These results suggest that high-density development strategies can be effective even in smaller cities and highlight the importance of neighborhood-level planning that achieves a balance between concentration and equity. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.11 10.4028/p-ksnhY4 Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Yi Kai Hsieh, Zhe Peng Xu <br />In light of global climate change mitigation goals and the transition toward net-zero carbon cities, this study investigates the relationship between urban spatial configurations and pedestrian behavior, with a particular emphasis on designing therapeutic and walkable environments. By employing Space Syntax analysis and pedestrian trajectory simulations within a Transit-Oriented Development (TOD) framework, this study identifies key spatial features influencing pedestrian hotspots. Notably, Unit 12 demonstrated the highest level of spatial integration (R3 = 4.951), despite the absence of sidewalks and the presence of fragmented arcade spaces interspersed with retail activity. This spatial condition reflects a strong correlation between integration values and pedestrian movement potential, even in environments lacking conventional walkability infrastructure. The findings highlight spatial variability across TOD zones and underscore the importance of area-based analysis over traditional station-centered approaches. Ultimately, the study advocates for urban design strategies that prioritize spatial continuity and psychological well-being, thereby contributing to sustainable, low-carbon urban lifestyles. These insights provide a foundation for inclusive and resilient spatial planning aligned with net-zero development goals. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.17 10.4028/p-D2YG1x Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Dongsung Bae, Kibong Kim, Jea Sun Lee <br />This study explores the required Level of Detail (LOD) in 3D urban models to elicit observation responses similar to those in real spaces. Through experiments involving 30 participants, both real-world and 3D-modeled streetscapes were evaluated using psychological surveys and webcam-based eye-tracking. Results showed that higher model precision generally produced responses closer to those from real environments. However, inconsistencies appeared at higher LODs, likely due to fatigue or equipment limitations. Open horizontal spaces attracted greater attention, suggesting the need for detailed modeling in such zones. While a clear threshold of sufficient detail was not found, the findings highlight the potential of 3D models as substitutes for field observation and the necessity for standardized LOD criteria in urban simulations. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.25 10.4028/p-233CXv Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Maryam Malik, Parvesh Saini, Jahangir Alam, Atul Chugh <br />This paper examines how inflation, economic policy uncertainty (EPU) and urbanisation affect housing affordability in Australia. The study uses secondary-source data (ABS series) and a simple city panel (Sydney, Melbourne, Brisbane and Perth), in conjunction with the housing inflation component of the indicator (mortgage rate) to establish a connection, followed to show inflation and urbanisation are pressures exerting their stress on affordability in parallel. Sydney is shown to have experienced the largest annual rise (≈12.5%: 6.2pp inflation, 6.3pp urbanisation). The relatively linked movements were represented via weak inverse correlation (r≈−0.14), therefore we recommend separate state and federal policy levers for these returns to housing affordability. Low-income renters are often exposed to pay ≥30% of their income towards housing, while middle-income first-home buyers are now experiencing tighter serviceability and deposit requirements. Regional areas may appear to be cheaper areas to rent or purchase... yet likely contain unrecognised stress. We propose adjusted transitions over the near-term (indexed cap on rent movement, offset mortgage-stress for all welcome), followed by longer-term supply reforms (diminished approval times, mid-rise infill, Build-to-Rent), but acknowledge the limitations of our data collection that relates to a range of 12 months up to 2024. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.33 10.4028/p-Ja4lGw Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Nuno Dinis Cortiços <br />This study comparatively analyzed residential architecture in Santarém, Portugal, as a representative case for the broader inland Mediterranean context, evaluating vernacular, contemporary, and hybrid typologies in terms of thermal performance and cost-effectiveness. Traditional buildings, characteristic of Mediterranean climates, relied on high thermal mass and cross-ventilation for summer cooling but exhibited poor envelope insulation (average U≈1.4 W/m²K), leading to elevated winter heating needs (≈150 kWh/m²·year) and non-compliance with Nearly Zero-Energy Building (NZEB) standards. By contrast, contemporary NZEB-compliant solutions, optimized for Mediterranean conditions, employed high-performance insulation and mechanical ventilation with heat recovery (average U≈0.13 W/m²K; ~35 kWh/m²·year), offering enhanced comfort but requiring a significant initial investment (+75%) and long payback periods (~46 years). The hybrid approach, integrating Mediterranean vernacular strategies with targeted technological upgrades, presented the most effective compromise. It reduced energy consumption by ~50% (78 kWh/m²·year, net 39 kWh/m²·year with renewables), involved a moderate additional cost (~28%), and shortened the payback period to ~33 years. This typology demonstrates a feasible and regionally adaptable model for energy-efficient housing in Mediterranean settings, aligning climate-responsive design with current energy performance requirements. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.55 10.4028/p-Q6nF8w Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Iori Uehara, Yoshihito Kurazumi, Kenta Fukagawa, Tomonori Sakoi <br />Balancing thermal comfort and energy efficiency in buildings remains a key challenge. While HVAC systems regulate temperature directly, recent studies suggest that visual factors—such as horizontal illuminance and correlated color temperature (CCT)—can influence perceived thermal comfort through psychological mechanisms. This study examined how these visual factors affect thermal sensation and comfort in cooling environments (26–30°C). A controlled climate chamber experiment was conducted with 54 healthy female participants under varying air temperatures, illuminance levels (100–2900 lx), and CCTs (2800–5200 K). Mean skin temperature increased with air temperature but remained unaffected by variations in illuminance or CCT, indicating stable physiological responses to visual conditions. However, higher illuminance and CCT levels led to enhanced sensations of coolness, particularly at 30°C. Visual comfort also improved slightly with increasing illuminance, while CCT effects on comfort were modest and dependent on air temperature. These findings suggest that adjusting the visual environment can enhance thermal comfort without changing actual temperatures, supporting higher cooling setpoints (around 28°C) and contributing to energy-efficient building design. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.63 10.4028/p-jA2LdD Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Francesca Renato, Paulo Mendonça, Marta Calzolari, Pietromaria Davoli <br />While microclimate studies tend to focus almost exclusively on large cities and densely urbanized areas, small historical villages are often left out of the scientific debate, despite their potential in terms of climate resilience, cultural value, and sustainable tourism development. This study explores the case of Sistelo, a historical village in northern Portugal, to investigate outdoor microclimatic conditions in a rural and heritage-rich setting. The research was structured in two complementary phases: an on-site monitoring campaign conducted during a springtime heatwave, involving detailed measurements across various outdoor spaces in the village; and a subsequent digital modelling and microclimate simulation based on historical average climatic data using specialized software. The comparison between the measured data and simulated results highlights meaningful discrepancies and raises questions about the representativeness of standard models in smaller settlements. This work aims to serve as a first step toward a more inclusive approach to microclimate analysis—one that recognizes the role of peripheral and small-scale contexts in shaping more nuanced and locally grounded climate and planning strategies. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.69 10.4028/p-p0c2L1 Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Yi Liu, De Zheng Kong <br />A healing environment, as a therapeutic and rehabilitative spatial setting, leverages the user's environmental recognition process to enhance environmental psychological suggestion, thereby stimulating physiological and psychological self-healing abilities. Concurrently, as a vital therapeutic and rehabilitative space within healthcare, a healing environment necessitates the fulfillment of medical treatment demands and technological requirements, resulting in unique spatial characteristics with strong identifiable features. Based on the perspectives of patient and provider psychology and environmental needs, this study analyzes how women and children perceive healing environments. By considering the structural form and intrinsic characteristics of spaces, it identifies the recognizable features of women and children friendly healing environments in primary healthcare settings. Consequently, it extracts the influential factors of such environments in primary hospitals and establishes an index system for them. The research findings can serve as a reference for constructing women and children friendly healing environments in medical institutions or urban spaces. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.77 10.4028/p-Yf9IYZ Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Ma.

This study provides baseline estimates of the availability of waste fibers from abaca and pineapple leaf fiber (PALF) production that could be tapped in implementing fiber-reinforced concrete designs. Additionally, this study offers a new perspective on how incorporating waste fibers into concrete mix design can lead to reduced cement usage and a potential reduction in carbon emissions. Approximately 50 kt/yr of waste fibers are generated and remain untapped. Given their availability, using waste fibers from abaca and PALF production in the Philippines could displace between 1 to 25 kg cement/m3 of concrete, potentially resulting in an annual emissions reduction of 20 to 30 kt CO2-eq. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.85 10.4028/p-SbFd0z Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Felicia Wagiri, Shen Guan Shih, Julian Jauk, Milena Stavric <br />This paper presents a toolpath optimization strategy for 3D-printed ceramic structures, inspired by the continuous flow of weaving patterns. By adapting algorithms based on the Traveling Salesman Problem (TSP), the method generates uninterrupted extrusion paths that reduce retractions and minimize abrupt toolhead movements. This approach is validated through full-scale ceramic panel prints, examining the impact of pattern geometry, density, drying time, and shrinkage behavior. Results indicate that a panel with pattern density of 50–70%, combined with a 1.5 mm layer offset and a 2 mm fillet radius, produces the most stable and visually coherent prints. Additionally, the number of layers and toolpath sequence significantly affect drying rates and anisotropic shrinkage. This study highlights the potential of optimized toolpath design to improve both performance and aesthetic quality in clay-based additive manufacturing for architectural and industrial applications. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.93 10.4028/p-Xh5zSG Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Ivan Kraus, Takayoshi Aoki, Petra Olić Miloš <br />This paper presents an experimental investigation of a scaled C-shaped rammed earth wall subjected to displacement-controlled monotonic lateral loading. The specimen was constructed using traditional manual compaction of soil containing 2% lime and tested under significant vertical load. Full-field deformation measurement and localized instrumentation captured the non-linear response, including the onset of cracking at 0.2% drift, progressive stiffness degradation and base slippage. Combined failure due to shear– and bending was observed. The results provide new experimental data on the seismic behavior of in-plane earth structures and contribute to the knowledge base needed for future numerical modelling and design of traditional rammed earth structures. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.99 10.4028/p-L95tz4 Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Viroon Kamchoom, Sumetha Chaisarn, Thiti Khattiwong, Laemthong Laokhongthavorn <br />Microbially induced bio-clogging presents a promising, sustainable alternative to conventional soil improvmeent methods for mitigating seepage in geotechnical applications. Despite its potential, uncertainties remain regarding the influence of bacterial concentration, culture medium application, and associated setting times under field-like conditions—factors which are critical to the effective deployment of this technology in practice. This study investigates the impact of bacterial bio-clogging on the hydraulic behaviour of coarse-grained soils, with particular emphasis on the system's performance during and following the cessation of culture medium supply. Laboratory experiments were conducted to assess the mechanisms of permeability reduction resulting from microbial colonisation and extracellular polymeric substance (EPS) production. Results demonstrate that bacterial adhesion and subsequent EPS accumulation lead to the progressive clogging of soil pores, causing a marked decline in saturated permeability. The observed reductions in permeability are comparable to those produced by traditional methods such as cement and bentonite grouting. This highlights the durability of the biofilm matrix and its ability to maintain hydraulic resistance in the absence of continued nutrient input. These findings contribute valuable insight into the viability of bio-clogging as a ground improvement strategy. By elucidating the relationship between bacterial activity, EPS production, and soil pore occlusion, this research advances the practical understanding required to optimise bio-mediated techniques for field-scale applications in sustainable geotechnical engineering. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.107 10.4028/p-tYG1UQ Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Chitrarekha Kabre <br />The Anglo-American term “eco house” is part of an emerging ecological hypothesis in architecture that prioritizes ecological responsibility for a sustainable future. This paper reviews and compares the technical, regulatory, and green rating frameworks applicable in India for sustainable habitat. Furthermore, the paper examines the extent of benefits achievable through Indian exemplar studies in three categories: best practices, green rating models, and solar models/net-zero energy models. Finally, the paper presents a cost-effective ‘Eco-house prototype,’ a design-build research project in Raipur. The house demonstrates the adoption of energy efficiency (both embodied and operational), water efficiency, and good indoor environmental quality measures, resulting in an ecologically sustainable habitat. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.117 10.4028/p-oG7g3d Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Jong Han Yoon, Syeda Roushan Arshid, Istiqlal Aurangzeb <br />Active shooter emergencies represent one of the most critical threats within the built environment. While numerous studies have aimed to enhance evacuation effectiveness, a comprehensive synthesis of existing research on evacuation systems for active shooter scenarios remains limited. This paper presents a systematic literature review of such studies, revealing that 1) current evacuation simulation systems lack real-time route optimization and rely on oversimplified floor plans, 2) evacuation facilitation systems overlook critical data such as shooter location and movement, and 3) evacuation training systems fail to offer scenario-specific guidance within actual building layouts. Based on these findings, this study outlines future research directions, including the development of IoT-enabled systems for real-time data sharing, advanced simulation models using detailed building spatial data, evacuation facilitation systems informed by active shooter dynamics, and training systems grounded in real-world building spatial data. These directions advance the understanding of active shooter evacuation by enhancing simulations, support systems, and training, ultimately helping reduce casualties in built environments. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.127 10.4028/p-Ta0oSL Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Lorie Mae Bello <br />Morphometric analysis has been conducted to measure a river basin's linear, aerial, and relief aspects. Studies showed that basin morphometry has a relationship with the hydrologic phenomenon of a river basin, thus influencing occurrences of floods, run-off, erosion, and channel abrasion. The Binahaan River in Leyte, Philippines, has a history of frequent flooding events that average more than one damage-causing event yearly. The study aimed to determine the morphometric parameters of the Binahaan River basin and evaluate their implications for hydrologic processes, most specifically, flooding, using a Geographic Information System (GIS) to delineate, extract, and analyze the parameters. The study revealed the flood susceptibility ranking of the sub-catchments: High (catchments 6 and 7), Intermediate (catchments 1 and 5), and Low (catchments 2, 3, and 4). Catchments 6 and 7 were noted to have high basin relief, relief ratio, ruggedness number, and mean bifurcation ratio with low circularity ratio and compactness coefficient. Validation through interviews and georeferencing with existing flood hazard maps also mainly showed the same results. The study presented that morphometric analysis and GIS can be utilized to analyze drainage basins comprising large areas with time constraints but still yield accurate data. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.139 10.4028/p-us7hGU Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Rubén Esaú Mogrovejo Gutiérrez, Richard Leon Jeanneau Cervantes, Ederson Huamanrimachi Huaman, Estefanie Isabel Quiroz Sandoval <br />In the world, non-Newtonian flows, also known in Peru as landslides, currently generate human and, above all, material losses, and they are activated when heavy and prolonged rains occur. The magnitude and frequency of these phenomena have increased in the last 50 years not only due to the lack of management of water resources in streams, but also now due to the effects of climate change that has generated a change in the regional and local water cycle. <br />To analyze this vulnerability in the Tinajas stream with 13km in length, a field campaign was executed and important precipitation data collection, then with the definition of the conceptual model a numerical model was applied, the latter was validated with a water footprint that occurred in 2017, with this methodology, the location of control structures called dikes of 150 m long, 5m wide and 4m high in strategic areas in the creek was proposed, and predictive scenarios were simulated to evaluate the contribution of the containment dikes to the vulnerability of this non-Newtonian mixture that converges more frequently in the Tinajas creek. <br />The results of the hydrologic scenarios were analyzed with and without the control structures, obtaining up to 60% containment for a 200-year hydrologic event. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.147 10.4028/p-ihDVm5 Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Yosuke Suzuki, Hiroaki Terasaki, Ziyi Jia, Hiroshi Nakayama, Yoshiki Nishihara, Yoshimasa Onishi <br />This study investigated the performance and life cycle costs of a snow-melting system that employs waste heat from a building in the Matsunokitouge parking area of Takayama City, Gifu Prefecture. The average center temperature of the interlocking blocks and air temperature inside the pallets in the snowmelt area were 4.8°C and 9°C higher, respectively, than those in the non-snowmelt area during the short-term observation period. Snowmelt occurred in this system when the outdoor temperature was −2°C or higher and the snowfall rate was 2.5 cm/h or lower. The life cycle costs estimated based on the experimental results generally became lower than those of the conventional system within ten years. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.157 10.4028/p-K4DXSu Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): David King Jair, Ming Chun Hsieh, Chia Pin Lin <br />This study presents a hybrid solar thermal self-regulating power generation system, designed for installation on rooftops and other small spaces. In addition to functioning as a solar water heater, the system also incorporates a power generation mechanism, promoting the adoption of green energy within general households beyond industrial or government contexts. Unlike conventional solar systems that are often constrained by cost and space requirements, this device can be easily added to existing structures, enhancing user acceptance and facilitating broader participation in energy conservation and carbon reduction efforts. Experimental results shows that at the temperature difference between the thermoelectric modules reaches 17.5°C, the system can generate up to 23W of electrical power. Even during nighttime, the system can still generate electricity by utilizing the thermal energy stored in the water tank during the day, achieving an output power of up to 10W. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.163 10.4028/p-DND7qx Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Lady Shirley Condor Peña, Diana Araceli Colca Chipana, Shura Nancy Casavilca Vergaray, Almendra Marcia Fonseca Daviran <br />Las comunidades rurales enfrentan acceso limitado al agua gestionada de manera segura, un problema agravado por las lluvias impulsadas por el viento y la variabilidad climática. Este estudio presenta, a escala de prototipo, un sistema móvil autónomo de recolección de lluvia cuyo embudo se reorienta automáticamente hacia la dirección predominante de la precipitación, superando la ineficiencia de los colectores estáticos. El dispositivo combina un embudo de acero galvanizado montado en un poste de acero con un servomotor controlado por Arduino, un anemómetro, un inclinómetro y un pluviómetro de cangilones basculantes, todos alimentados por un módulo fotovoltaico; un bajante de PVC canaliza el agua a un tanque de HDPE de 250 L. Las pruebas de campo en San Francisco de Asís, Ancalahuata, distrito de Chilca, Huancayo, Perú, compararon el prototipo con un colector estático de igual área proyectada. La unidad móvil capturó entre un 40 % y un 81 % más de agua; una prueba de Kolmogorov-Smirnov confirmó la normalidad y una prueba t independiente arrojó p &lt; 0,01, lo que indica una mejora significativa. El tiempo promedio de reorientación para fijar la dirección dominante fue de 3,7 s, y la eficiencia se mantuvo bajo ráfagas de 22 km h⁻¹. Las encuestas (n = 12) mostraron un 92 % de intuición percibida y un 100 % de aceptación. Los resultados demuestran que una arquitectura móvil, autoalimentada y autoorientable para la captación de agua de lluvia puede aumentar significativamente la disponibilidad de agua en zonas rurales, manteniendo la simplicidad estructural y la aceptación social. En el futuro, se ampliará el diseño, se optimizará la lógica de control para condiciones extremas y se realizarán evaluaciones del ciclo de vida para facilitar su implementación en regiones con escasez de agua. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.173 10.4028/p-7Qg4oc Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Francesca Porcellini, Enrico Pasquale Zitiello, Eliana Basile, Antonio Salzano <br />Faced with today's critical issues in the management and maintenance of infrastructures - due to factors such as age, structural complexity and the limitations of traditional inspections - this study systematically addresses the entire set of maintenance issues, proposing the integrated use of innovative digital technologies as an answer. The research presents an advanced methodology based on the synergy between Building Information Modeling (BIM), Internet of Things (IoT) and Machine Learning (ML), with the aim of supporting the predictive and dynamic management of infrastructures through the creation of Digital Twins. In this paper, this methodology is applied to two case studies of bridges in Italy, which are currently being monitored. The application focuses on the initial stages of the process: digital modelling of the works (with the creation of BIM models containing static data), installation of sensors for the collection of dynamic data in real time, and subsequent integration of this information for the generation of a functional Digital Twin. This unified model allows not only the management of warning systems based on predefined thresholds, but also the elaboration of in-depth structural diagnoses to support the planning of maintenance interventions. The proposed methodology also represents a strategic step towards the evolution of advanced predictive models, favouring a more proactive, efficient and sustainable approach to maintenance. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200 https://www.scientific.net/AST.173.183 10.4028/p-TFmGU9 Publication date: 11 February 2026 <br />Source: Advances in Science and Technology Vol. 173 <br />Author(s): Da Hee Kim, Wi Sung Yoo, Jong Woo Son, Wang Young Jung, Jong Soo Lee, Seong Mi Kang <br />The domestic construction industry continues to face persistent productivity challenges, often leading to increased project costs and schedule delays. Despite considerable advances in digital technologies, the practical implementation of digital solutions at construction sites remains limited, due to insufficient consideration of realistic working conditions and user needs. In this study, a digital supervision system optimized for mobile devices was developed to digitize core supervision processes, including inspection request confirmation, inspection execution, result notification, and access to supervision records. Investigation was adopted, involving experts with over 15 years of field experience, to systematically evaluate the usability and field applicability of the system. The assessment focused on four key domains: physical accessibility and usability, improvement of work efficiency, ease of learning and accessibility, and reflection of existing work practices. Both importance and performance were rated for each domain, and the gaps were analyzed to identify priority areas for improvement. The results revealed that the integration with existing workflows was the most critical factor for successful adoption, yet also exhibited the greatest performance gap. While the system excelled in data management and retrieval, there remained a strong need for further automation and enhanced user guidance, particularly in inspection execution. All participants expressed a high intention to use the system in the future, underscoring its potential value despite current limitations. This study highlights the necessity of user-centered approaches in digital system development and provides practical recommendations for advancing the digital transformation of construction supervision. Future research should expand the sample size and construction types to validate and refine these findings. <br /> <br /> Wed, 11 Feb 2026 00:00:00 +0100 Fri, 10 Apr 2026 07:34:00 +0200
