Modular integrated construction (MiC) has been introduced in high-rise construction for achieving sustainable development. As high-rise MiC disruptively transforms the construction process compared with conventional construction, it is imperative to systematically understand its performance, which however has not been sufficiently reported in previous literature. Therefore, this paper aims to develop a new framework of key performance indicators (KPIs) for project stakeholders to comprehensively measure and effectively benchmark the performance of high-rise MiC projects. This framework is developed based on the concept of sustainable construction that covers social, environmental and economic aspects. Through a comprehensive literature review, expert interviews, and a focus group meeting, 32 KPIs are established in the three sustainability aspects. An eight-step process is suggested for project stakeholders to adopt these KPIs to measure MiC performance in three tiers, i.e., overall building, off-site and on-site, and modular works. A case study is then presented which demonstrates that the framework is effective in measuring the sustainability of high-rise MiC and applicable for comparing MiC with conventional practices. The framework fills the knowledge gap of performance measurement on high-rise modular construction and contributes a methodological foundation for future quantitative benchmarking of MiC sustainability.

In this article, the authors consider the socioecological problems that arise in the construction and operation of high-rise buildings. They study different points of view on high-rise construction and note that the approaches to this problem are very different. They also analyse projects of modern architects and which attempts are made to overcome negative impacts on nature and mankind. The article contains materials of sociological research, confirming the ambivalent attitude of urban population to high-rise buildings. In addition, one of the author’s sociological survey reveals the level of environmental preparedness of the university students, studying in the field of "Construction of unique buildings and structures", raising the question of how future specialists are ready to take into account socioecological problems. Conclusion of the authors: the construction of high-rise buildings is associated with huge social and environmental risks, negative impact on the biosphere and human health. This requires deepened skills about sustainable design methods and environmental friendly construction technologies of future specialists. Professor M. Eichner presents in the article his case study project results on implementation of holistic eco-sustainable construction principles for mixed-use high-rise building in the metropolis of Cairo.

The aim of the paper is to demonstrate the widely presented benefits of modular construction as compared with traditional construction method. A case study of family house construction by modular building method and traditional method is used to examine the structural, economic and time indicators of individual construction methods. The results are presented in tabular and graphical outputs and are compared each other in regard to different technological parts of the building. The paper provides the comparison of economic and time indicators resulting from budgets and time schedules of construction that are executed for different variants. Such comparison demonstrates exactly the benefits of modular construction. The building based on building modules consisted of steel bearing structure and enveloped by sandwich panels is adopted as the selected modular construction technology. The different variant, applied for comparison of modular and traditional construction, is represented by the building with comparable thermo-technical characteristics, constructed by traditional masonry method.

Mass Timber

Due to the inherent inefficiencies in conventional approaches followed in the construction industry and the global demand for lean and sustainable construction techniques, modular construction has witnessed a resurge especially in high-rise buildings. As such, much efforts have been put in studying the use of mass timber for the main structure of high-rise buildings in order to ensure more sustainable developments with high levels of adaptability. In this regard, previous research efforts have primarily focused on the added benefits of mass timber, its structural design and performance, and associated safety requirements. However, owing to the novelty in combining modular processes with timber materials and associated lack of data, several regulatory barriers and contractual issues still exist. To mitigate these issues, this paper studies the specifics of permit approvals and contracting issues in timber high-rise modular buildings. The objective is to develop a comprehensive up-to-date review and analysis of the relevant practices and to conduct interviews with industry experts to analyze their concerns, given the insufficient number of guides and building codes that dealt with these issues. Hence, our study investigates the process of obtaining permit approvals from local jurisdictions in Ontario in addition to the requirements for submission of additional documentation, engineering analysis, and testing. Moreover, it analyzes the initial stage of contractual agreement of stakeholders under the uncertainties imposed on these buildings and evaluates the suitability of Integrated Project Delivery (IPD) contracting method. Presenting detailed analysis of the initial planning stages for timber high-rise modular buildings can in turn suggest the best practices to be taken into consideration for the successful implementation of these buildings under the current building code.

Abstract Early childhood education has long-lasting influences on people, and an appropriate companion toy can play an essential role in children's brain development. This paper establishes a complete framework to guide the design of intelligent companion toys for preschool children from 2 to 6 years old, which is child-centered and environment-oriented. The design process is divided into three steps: requirement confirmation, the smart design before the sale, and the iterative update after the sale. This framework considers the characteristics of children and highlights the integration of human and artificial intelligence in design. A case study is provided to prove the superiority of the new framework. In addition to enriching the research on intelligent toy design, this paper also guides for practitioners to design smart toys and helps in children's cognitive development.

To transform the negative impacts of buildings on the environment into a positive footprint, a radical shift from the current, linear ‘make-use-dispose’ practice to a closed-loop ‘make-use-return’ system, associated with a circular economy, is necessary. This research aims to demonstrate the possible shift to a circular construction industry by developing the first practical framework with tangible benchmarks for a ‘Circular University Campus’ based on an exemplary case study project, which is a real project development in India. As a first step, a thorough literature review was undertaken to demonstrate the social, environmental and economic benefits of a circular construction industry. As next step, the guideline for a ‘Circular University Campus’ was developed, and its applicability tested on the case study. As final step, the evolved principles were used to establish ‘Project Specific Circular Building Indicators’ for a student residential block and enhance the proposed design through bioclimatic and regenerative design strategies. The building’s performance was evaluated through computational simulations, whole-life carbon analysis and a circular building assessment tool. The results demonstrated the benefits and feasibility of bioclimatic, regenerative building and neighbourhood design and provided practical prototypical case study and guidelines which can be adapted by architects, planners and governmental institutions to other projects, thereby enabling the shift to a restorative, circular construction industry.

Civilian control of the military is a fundamental attribute of democracy. While democracies are less coup-prone, studies treating civilian control as a dependent variable mostly focus on coups. In this paper, I argue that the factors predicting coups in autocracies, weaken civilian control of the military in democracies in different ways. To capture this difference, I advance a new comprehensive framework that includes the erosion of civilian control by competition, insubordination, and deference. I test the argument under conditions of an intrastate conflict—a conducive environment for the erosion of civilian control. A large-N analysis confirms that while intrastate conflict does not lead to coups in democracies, it increases the military’s involvement in government, pointing to alternative forms of erosion taking place. Further case study—Russia’s First Chechen War—demonstrates the causal logic behind the new framework, contributing to the nuanced comparative analysis of civil-military relations across regimes.
