The purpose of this study is to conduct a rigorous systematic literature review and present a summary of building systems and technologies that can be used to mitigate the spread of airborne viruses. With the recent outbreak of COVID-19, occupants’ health and indoor air quality (IAQ) have become a critical issue for facility managers to maintain the full functionality of the buildings. An improved understanding of these available systems will help facility managers and building owners to protect the health and safety of building occupants.

The PRISMA protocol was used for defining the literature search methodology. The concept mapping technique was used for determining the keywords. The keywords were then used to search for relevant articles using the Scopus database and Google Scholar. A thorough bibliometric analysis and qualitative analysis were conducted for the selected publications.

It was found that sensor technologies, botanical air-filtration systems and artificial intelligence could be used to effectively monitor and improve IAQ. In addition, natural ventilation is one of the low-cost and effective methods of reducing contaminants from the indoor air. Computational fluid dynamic modeling can be used to understand the flow of virus particles within the building through the heating, ventilation and air-conditioning (HVAC) system. Several changes to the HVAC system are also discussed.

This study contains a diversity of methods from the existing literature that were systematically selected to present the state-of-the-art building systems and technologies that can effectively improve IAQ. The researchers plan to follow up on the findings of this research and will conduct an empirical study to assess its impact on IAQ.

The Operations and Maintenance (O&M) cost of a facility is typically 60–85% of the total life cycle cost of a building whereas its design and construction cost accounts for only 5–10%. Therefore, enhancing and optimizing the O&M of a facility is a crucial issue. In addition, with the increasing complexities in a building's operating systems, more technologically advanced solutions are required for proactively maintaining a facility. Thereby, a tool is needed which can optimize and reduce the cost of facility maintenance. One of the solutions is Augmented or Mixed Reality (AR/MR) technologies which can reduce repair time, training time and streamline inspections. Therefore, the purpose of this study is to establish contextual knowledge of AR/MR application in facilities operation and maintenance and present an implementation framework through the analysis and classification of articles published between 2015 and 2022.

To effectively understand all AR/MR applications in facilities management (FM), a systematic literature review is performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) protocol was followed for searching and describing the search strategies. Keywords were identified through the concept mapping technique. The Scopus database and Google Scholar were employed to find relevant articles, books and conference papers. A thorough bibliometric analysis was conducted using VOS Viewer and subsequently, a thematic analysis was performed for the selected publications.

The use of AR/MR within facilities O&M could be categorized into five different application areas: (1) visualization; (2) maintenance; (3) indoor localization and positioning; (4) information management and (5) indoor environment. After a thematic analysis of the literature, it was found that maintenance and indoor localization were the most frequently used research application domains. The chronological evolution of AR/MR in FM is also presented along with the origin of publications, which showed that the technology is out of its infancy stage and is ready for implementation. However, literature showed many challenges hindering this goal, that is (1) reluctance of the organizational leadership to bear the cost of hardware and trainings for the employees, (2) Lack of BIM use in FM and (3) system lagging, crashing and unable to register the real environment. A preliminary framework is presented to overcome these challenges.

This study accommodates a variety of application domains within facilities O&M. The publications were systematically selected from the existing literature and then reviewed to exhibit various AR/MR applications to support FM. There have been no literature reviews that focus on AR and/or MR in the FM and this paper fills the gap by not only presenting its applications but also developing an implementation framework.

The purpose of this paper is to present findings of a capacity building project on construction health and safety that is recently completed in Pakistan. The major objectives of this project are: first, to benchmark the current state of construction health and safety practices in Pakistan and to identify the data needs for continuous performance measurement; second, to develop health and safety guidelines; third, to develop adequate educational and training material; and finally, to improve the existing regulatory infrastructure for worker health and safety.

Mixed-methods approach is adopted for data collection which included site observations, surveys, semi-structured interviews, and case studies. The methodology consists of following major tasks: first, literature review and study of best practices; second, investigation of existing safety practices and development of guidelines; third, educational and training programs for construction professionals and educators; and finally, development of a strategic framework for continuous improvement in construction safety culture, laws, and practices. Collected data were analyzed using various qualitative and quantitative data analysis methods.

The enforcement of health and safety regulations on construction sites is very limited in Pakistan. Procedures for formulating, implementing, and monitoring safety rules and regulations are weak, and the implementation of safety management systems does not occur on most construction sites. The paper presents a detailed plan to improve the health and safety culture, laws, and practices in Pakistan.

Detailed proposals for improving existing construction health and safety laws and regulations are prepared for relevant regulatory and statutory bodies and ministries in Pakistan. From an educational perspective, comprehensive health and safety training material are developed and training workshops are conducted in major cities of Pakistan. Over 1,000 construction professionals benefited from these workshops.

The project helped in raising awareness about construction health and safety in Pakistan.

The project benchmarked existing health and safety practices in Pakistan. It identified data needs for continuous monitoring of health and safety performance and provided a mechanism for collecting such data. The project produced international standard health and safety training material that can fulfill the local needs. The project deliverables are extremely helpful for other developing countries in the region.

This paper identified the ṣukūk structure suitable for deficit financing during the COVID-19 crisis. The study also explored the relevant Sharīʿah contracts that could be utilized to issue ṣukūk that is suitable for various jurisdictions and corporations in handling deficit financing during the COVID-19 crisis.

The authors have adopted a qualitative research approach in which primary and secondary sources available on the subject were reviewed, especially a number of cases related to ṣukūk structures prior to and during the COVID-19 crisis and analyzed their performances and drawn their conclusions.

The outcome of this paper suggests that certain ṣukūk structures used during the COVID-19 crisis aimed primarily at financing deficit have been successful. Furthermore, these ṣukūk structures are relied very much on the obligator’s/issuer’s cash flow position. It has been revealed that if the ṣukūk is structured on equity-based contracts with lower repayment amount or no payment, it would not trigger default because the nature of this ṣukūk is the sharing of profit and loss, in accordance with a Sharīʿah rule that there will be compensation for any loss only if deliberate and notable negligence is proven. However, if it is debt based or ijarah and wakalah contracts, then the payment to ṣukūk holders ought to be made as agreed and if not, it will trigger default. This payment is to be made from the cash flow of the issuer and if there is an issue in the cash flow of the issuer due to COVID-19, consent from the ṣukūk holders needs to be obtained to reschedule payment as found in the case of the Garuda Indonesia ṣukūk. However, as found in MASB’s IMTN ṣukūk case, if the cash flow of the company is good, then the chances of default are very slim. However, so far, three new ṣukūk in the middle of COVID-19 were issued, one by a corporation and two issued by a sovereign, one of which addresses the liquidity issues during the pandemic, and all these proved that ṣukūk is definitely a viable alternative mode for deficit financing and a reliable option during the COVID-19 pandemic.

This paper looked into the ṣukūk structure, especially the ṣukūk which are yet to mature and the new ṣukūk issued during the crisis caused by the COVID-19 pandemic.

It is anticipated that the outcome of this research will assist the stakeholders in ṣukūk markets to understand the ṣukūk impact on COVID-19 related deficit financing and suggest various structures that could be utilized in the ṣukūk market in an unprecedented situation such as the COVID-19 economic distress.

Looking at the social aspect of ṣukūk markets, this paper has endeavored to provide solutions to the financing of deficit for social well-being as a tool to provide relief and social stability in the lives of the people.

The novel COVID-19 pandemic has caused unprecedented economic difficulties and market distress on a global scale; and this research sought to identify the relevant ṣukūk structures to be used for deficit financing during the pandemic crisis, especially the ṣukūk which are yet to mature and new ṣukūk issued during the pandemic crisis. The former includes HDFC Muḍārabah ṣukūk (2019) Maldives and MAHB ṣukūk/IMTN program (2010) Malaysia, while the latter includes IsDB Trust Certificates, Phase 2 of the tranches (2020), the Federal Government of Nigeria Road ṣukūk (May, 2020) and Sharj’ah Government two billion Dirham ṣukūk (June, 2020).
