Construction Automation and Robotics is the anticipated technology to overcome productivity issues and work accidents. This research aims to analyze the implementation of Construction Automation and Robotics at Indonesian Construction SOEs from the perspective of real project implementation based on project life cycle, comparison with best practices, and potential uses, through the qualitative-comparative analysis of the literature as well as questionnaires and in-depth interviews. It attempts to report how this technology is implemented in Indonesia as a comparison tool for other countries. This research identifies that seven Indonesian Construction SOEs have been using Construction Automation and Robotics technology, where Drones, Virtual Reality, and Prefabrication and Modularization are the most popular and mostly implemented in the construction phase. Compared to best practices, those implementations are still in the adoption stage. It has not reached its full potential through the development stage due to insufficient collaboration between contractors, technology companies, and universities. Although the construction market in Indonesia has not directly demanded in-project applications, this technology is potentially considered to improve the completion of construction projects, especially the interaction prospects of Digital Twin and BIM. This study provides complete positional information on Construction Automation and Robotics type in the project life cycle in theory and practice as a benchmark for construction technology research. This study fills the research gap and pioneers Indonesia’s Construction Automation and Robotics implementation research in international journals by providing the latest and comprehensive overview and comparing it to good practices from the USA and China.

India is one of the countries with the strongest agricultural production, hence leading to accumulation of the wastes and therefore leading pollution to the environment. Researchers are using different methods for using this agricultural and industrial waste by-products for construction purposes to safeguard natural sources like limestone, and river sand. By utilizing these materials in the construction sector, the material cost can be brought down to some extent and it also helps the environment to be free from pollution. This research paper object to the usage of Sugar Cane Bagasse Ash (SCBA) (Agricultural Waste) and Quarry Dust (Q.D) (Industrial Waste) as a partial substitution for cement and sand respectively to reduce the scarcity of the limestone and river sand. SCBA was replaced with cement in different levels of replacements 5%, 10%, 15%, 20%, 25%, 30%, 35%, and 40% respectively. The different tests were done to find out the performance of the concrete and the results were compared with the conventional mix. SEM analysis was done to find out the particle dimensions and composition of the materials. The compressive strength of the specimens was increased upto the level of 35% and then it was noticed that the strength got decreased. The content of SCBA got decreased beyond 35% due to the material characterization and relatively more voids in the preparation of concrete specimens, resulting in the reduction of density of concrete. So that the test results are proven that the SCBA can be replaced by 35% (Optimum level).

Despite widespread enthusiasm, there is little research on the performance of students, especially architecture students, in courses offered with open educational resources (OERs). The objective of this research is to develop and adopt an open educational resource (i.e., an open web-based multimedia platform) for teaching an architecture course and assess the effects of the open educational resource on improving the performance of architecture students. The building information modeling (BIM) course, taught to architecture, engineering, and construction students at the University of Texas at Arlington, was selected as the testbed. This study aimed to comparatively examine the performance of architecture, engineering, and construction students in the BIM course before and after adopting the open educational resource. Hypothesis tests were performed to compare the averages of students’ project and overall grades in two semesters that the BIM course was offered with and without the open educational resource. Analysis of Variance (ANOVA) and Analysis of Covariance (ANCOVA) tests were used to assess the potential main and interaction effects of the open educational resource and control variables (i.e., GPA, major, employment status, family background, field experience, effort level, and past BIM experience) on the students’ overall or project grades. The averages of project and overall grades were improved in the semester that the open educational resource was provided. The results of t-tests show that these improvements in the average project and overall grades have been statistically significant. The results of ANOVA and ANCOVA tests show that the open educational resource was a significant factor in improving average overall and project grades even after considering the effects of the control variables. It is expected that the open educational resource helps architecture students succeed in the Building Information Modeling course, which is an essential component of a modern architecture curriculum.

Design methods, frameworks, and green building certifications have been developed to create a sustainable built environment. Despite sustainability advancements, urgent action remains necessary due to climate change and the high impact of the built environment. Regenerative Design represents a shift from current practices focused on reducing environmental impacts, as it aims to generate positive effects on both human and natural systems. Although digital design methods are commonly employed in sustainable design practice and research, there is presently no established framework to guide a digital regenerative design process. This study provides an analysis of existing literature on regenerative design and digital design methods and presents a framework based on building information modelling (BIM) methodology and computational design methods, that can be applied to both urban and building design. This framework identifies digital tools and organizes indicators based on the pillars of climate, people, and nature for regenerative design, drawing upon a comprehensive analysis of literature, including standards, sustainability frameworks and research studies. The framework is illustrated through a case study evaluation. The paper also highlights the potential and limitations of digital methods concerning regenerative design and suggests possibilities for future expansion by incorporating additional quantifiable indicators that reflect research developments, to achieve positive outcomes.

Abstract

Sports complexes and recreational centers are large and long-term investments that provide integrated facilities for training athletes and hosting social-cultural events. Due to their daily functioning, such buildings involve high energy consumption resulting in environmental impacts at both local and global scales. This article investigates the currently available methods for assessing the performance characteristics of a Multipurpose Hall using passive design techniques by modifying the building materials used for the wall envelope and fenestration design. Given that the proposed Multipurpose Hall is located near the composite climate of New Delhi, India, a study of climatic responses together with an energy evaluation of the building provides insight into the important envelope design for enhancing a building's energy efficiency. Several energy simulations were performed using DesignBuilder software to determine the annual lighting, heating, and cooling consumption for wall envelopes, window glazings, and dynamic shading techniques. Additionally, the solar gain of various fenestration designs was investigated, and the most energy-efficient building envelope was selected. The comparison of the baseline envelope with the modified envelope design revealed a notable improvement in energy performance.
