Abstract: A base isolator is a proven system that can significantly reduce any damage to a building in the event of an earthquake. Despite their efficacy, seismic isolators are not widely used in New Zealand, with only about forty systems in use during the 2010 and 2011 Canterbury Earthquakes. This study seeks to investigate why base isolation systems are not frequently used in seismic strengthening projects and buildings in New Zealand. It also focuses on determining ways in which seismic isolators could become more widely used in New Zealand due to increased seismic activity. This study used an exploratory sequential mixed method design, in which qualitative data were collected first through in-depth face-to-face interviews, analysed, and used to construct the quantitative instrument, which was an online questionnaire. Data were obtained from construction professionals such as architects, engineers, site-based construction personnel, and quantity surveyors. The findings of this study indicated the need for an increased awareness of base isolation systems and improved universal guidelines for the design of seismic isolators. The motivators identified include provision of monetary incentives, such as reduced insurance premiums and financial subsidies, to encourage the adoption of seismic isolators. The factors preventing the adoption of base isolation systems in New Zealand were classified as human-related, safety and design-related, and cost-related. The study’s implication is that providing a universal guideline for seismic isolators can enhance designers’ confidence. Likewise, incentives may be provided to property owners to lower the cost of implementing a base isolation system.

Abstract: The construction and built environment sector is dynamic. It is made up of professionals who are knowledgeable about design, planning, construction and cost estimation. Design is one of several courses undertaken by construction students. Assessing design drawings is demanding for tutors as the assessment criteria need careful consideration. Assessment results may encourage or discourage students. Their morale may be affected if they feel their efforts have not been rewarded. Achieving a balance between the tutors’ decisions and students’ satisfaction is therefore important. This research sought to identify factors affecting students’ satisfaction with grades in design courses. The study was undertaken among year 3 and 4 architecture students in a Nigerian university. One hundred and twenty students were invited to reply to an online questionnaire. Their responses revealed that most of them were not satisfied with their tutors. They felt that marking was inconsistent. This study identified a range of ways students felt assessment could be improved. Chief amongst these was a suggestion that the same tutors assessed the work of all students (rather than for several tutors to be involved). Based on these issues, the paper suggests ways to balance tutors’ assessments and students’ satisfaction.

Abstract: Providing shelters for animals during disasters such as floods, bushfires and storms requires adequate planning and preparedness. Planning for animals during the disaster response and recovery phases is critical to mitigating the negative effects that animal loss or separation can have. The human-animal bond has the potential to influence people’s decisions during emergencies, such as how they will respond and when or if they will evacuate. Evacuation with animals during a disaster event can be difficult and complicated. It is critical, however, that animals are rescued and kept safe during and after disasters. Any compromise can result in the death of such animals. Similarly, even in disaster-related situations, animal handling should be consistent with the Australian Animal Welfare Standards and Guidelines. This project aims to better understand disaster preparedness and resilience, as well as the recovery of animals during a disaster event. Twenty-five potential animal evacuation sites, including saleyards, showgrounds, animal shelters, and racecourses, were identified and accessed in nine local government areas (LGAs) across the Hunter region of New South Wales, Australia. On-site survey using a 5-point Likert scale questionnaire was used to collect data. While none of the facilities are of high standard, 16% would require cosmetic work, 76% would require minor work, and the remaining facilities would require significant work. The project’s implication is that the assessment guideline can be included in the local council’s emergency management plan to improve adequate planning for safe animal evacuation.

Abstract: The construction industry is faced with many challenges, among which is waste management. Aside from the fact that wastage contributes to time and cost overrun, it also has environmental implications in the form of pollution. However, the industry has the capacity to effectively manage waste, from generation to disposal. All stages of the management process are important, but scholars and governments have provided the final step, being disposal, unabated attention in order to ensure effective management. Potential waste disposal methods, including incineration, burning, landfilling, recycling, reuse, open dumping, pyrolysis, and shredding have emerged from the literature around the globe. Despite various waste minimisation and sustainable disposal options that are available, construction material waste is still increasing in Nigeria, while disposal remains a major issue for firms and government. Therefore, this study assesses disposal methods among construction firms to determine whether there is a relationship between their practices towards waste disposal. The research followed a concurrent triangulation design in a cross sectional survey, while data were collected via a convergent parallel mixed methods. The quantitative phase employed a structured questionnaire to collect data from 243 building construction firms, while the qualitative phase involved semi-structured interviews with 65 professionals from 10 on-going construction projects in Lagos, Nigeria. The research revealed that landfilling is the most common method of waste disposal, which is closely followed by reuse as backfill and recycling. In addition, the study revealed no association between company’s ownership statuses, age, project specialisation, and disposal methods, except company’s size. In conclusion, the study establishes the need for regulatory policies, such as site waste management plan (SWMP), pay as you throw (PAYT), and landfill ban, which would minimise material waste and ert them from landfills. Recycling and reuse are recommended as sustainable approaches for waste disposal.

Abstract: As an alternative to the linear economy concept, the circular economy (CE) is growing in popularity among researchers, governments, and organisations. It is a waste-elimination concept that takes, creates, uses, and regenerates materials. Although the CE concept has been adopted in a variety of industries and countries, its application in Africa, particularly in the built environment sector, is still in its early stages. A lack of adequate research on the subject could be one of the reasons for the slow uptake in the built environment. In this context, the study provides an overview of publications focusing on CE in Africa’s built environment from 2001 to 2021. Through the Web of Science database, this study identifies various key topics and CE implementation methods in Africa using bibliometric analysis. The findings show that 92 publications in Africa focused on CE and the built environment over a 20-year period. Using the VOS viewer software, data analysis focused on the document type, year of publication, journal distribution, top authors, most cited publication, and keywords. In conclusion, the study suggests that vigorous research on the CE concept be conducted, with a focus on waste minimisation, in order to reduce pollution in the long run.

Abstract: The circular economy (CE) concept is gaining traction as a sustainable strategy for reducing waste and enhancing resource efficiency. This concept has been adopted in some countries such as Denmark, Netherlands, Scotland, Sweden, Japan, China, and Germany while it is being considered by others including England, Austria, and Finland. The CE has been employed in the manufacturing, agricultural, textile, and steel industries but its implementation varies. It is against this backdrop that this study seeks to identify CE implementation in three pioneering countries (China, Japan, and Germany). A critical review and analysis of the literature was conducted. The results revealed enabling and core policies/laws for the development of the CE concept. It also identified the implementation structure of the CE in China, Germany, and Japan. In conclusion, the findings of this study are expected to serve as a guide for developing and implementing the CE concept in various sectors of the economy.

Abstract: Fast-track construction projects are becoming increasingly prevalent in the construction industry, particularly where completion time is essential. A high adoption rate in some of the Gulf Cooperation Council (GCC) countries countries and the lack of a conceptual understanding of the challenges inherent in such may jeopardize the future sustainability of the construction sector. To make an informed decision about adopting a fast-track construction method, it is necessary to first identify the opportunities and challenges associated with it. Therefore, this study examines the critical challenges impeding the performance of Qatar’s fast-track construction projects. The research findings were analysed and triangulated using a real-life project as a case study and several data sources. The results of the research identified four critical categories of barriers: design and coordination-related, scope or change orders-related, material and equipment-related, and contractual-related barriers. In addition, strategies such as accurate information, constructability assessment, early involvement of operations and maintenance personnel, and the use of an effective change control system were identified for addressing the identified challenges. The findings are beneficial to professionals who are currently operating or planning to undertake construction projects in Qatar or other Gulf Cooperation Council (GCC) countries countries. This study recommends that project managers be more attentive to key barriers in order to improve the performance of fast-track projects and to meet clients’ objectives.

Abstract: Establishing a more sustainable built environment is an increasing global concern for the construction industry. Despite the intrinsic and extrinsic obstacles the stakeholders face, huge efforts are required to transition to a smooth, sustainable construction (SC) practice. This study identifies and discusses cogent obstacles to SC in developing nations. The Preferred Reporting Item for systematic reviews and Meta-Analysis (PRISMA) approach was employed to establish research work in SC for developing countries. The databases used were Scopus and Web of Science. Meta-analysis of keywords was analysed thematically. The initial broad search returned 8,420 publications which were filtered and reviewed in-depth to fit the aim of the study, produced only 21 relevant publications from the years 2000–2021. The four identified themes of obstacles to SC in developing countries are as follows: construction professional training and education, clients' attitudes and awareness, construction industries' culture and capacity and governments' regulation, policies and economy. The key barriers identified from the meta-analysis include inadequate training and education amongst construction professionals, poor execution of sustainability ethics, poor populace attitude towards sustainability, poor awareness and understanding, dearth of precise data and integrated study and inappropriate priorities about sustainability. The originality in this study are themes drawn from millennium development goals (MDGs) and sustainable development goals (SDGs) publications related to SC. Consequently, the final framework presented a holistic approach to surmounting the established limitations and aided recommendations for future studies. Thus, setting a background for developing strategies to overcome the limitations and further attain sustainable development (SD).
