“…Overall, it is found that time overrun/extension of time has the highest likelihood of occurrence with a value of 0.677. These results echo previous studies done by Obodoh and Obodoh (2016) and Hasan et al (2014), who concluded that “Time overrun” is the top effect of delays. The second most important effect found in this study is poor quality of work due to hurrying the project, with a LI value of 0.636.…”

Purpose This paper aims to measure the severity, frequency and importance of the factors causing delays in the United Arab Emirates (UAE) construction industry following the Covid-19 pandemic onset. The study also measures the likelihood of the effects caused by these delays. Design/methodology/approach A mixed approach of both qualitative and quantitative. Literature review was conducted to extract 40 factors of delays and 10 effects of delays. A survey was then administered to construction professionals in the UAE to collect the perceptions on the severity and frequency of factors of the causes of delays using a Likert Scale of 1–5 where 1 represented very low and 5 represented very high. Similarly, the respondents were also asked to rate the likelihood of the occurrence of the effects of the delays based on a Likert scale of 1–5 as well. Furthermore, Spearman’s rank correlation was also conducted to compute the level of agreement between the different parties; owner, consultants and contractors. Findings The results revealed that the top five factors of delays include: award the project for the lowest bidder, delay in progress payment, change orders by the owner, poor subcontractor performance and inadequate planning and scheduling by the contractor. The findings of this study emphasize the financial challenges and economic crisis brought upon the construction industry due to the pandemic. Furthermore, the pandemic also shifted the perceptions of construction professionals, who are now more aware of the delays caused by awarding the project to the lowest bidder who would not have the required qualifications to conduct efficient planning and scheduling that are relevant in the case of extraordinary events such as Covid-19. Moreover, a high level of agreement between the consultants and contractors was observed, with a Spearman’s rank correlation of 0.804. Additionally, the most likely effects of delays concluded from this study were time overrun/extension and poor quality of work. Originality/value Literature review is very rich in the field of construction projects delays. However, there is very limited research on the impact of Covid-19 in the context of construction projects delays, and insights from construction professionals regarding this matter are particularly lacking in literature. Therefore, this paper bridges the gap in literature by providing perceptions of construction professionals on the impact of Covid-19 on the factors causing delays in the UAE construction industry. The findings of this research are expected to be an invaluable resource for future to help the construction industry heal faster when encountering similar epidemics or extraordinary events.

“…It is, however, important to note that the maintenance of buildings in Indonesia has several similarities with other countries although the methods, technology, and skills of maintenance staff are applied in different ways depending on the level of technological development and skills possessed by human resources in each country. For example, the maintenance in Nigeria, which is a developing country, is very similar to Indonesia as indicated by the corrective, preventive, and predictive types usually applied [13,42,50,51,52]. Corrective maintenance is usually implemented after a breakdown, preventive to prevent damages while predictive involves predicting the time and scale of damage [9].…”

The Ampel Mosque in Surabaya is an important historical site for Muslims in Indonesia. The architecture of the Ampel mosque is strongly influenced by Javanese and Arabic culture. a very harmonious integration between Javanese architecture as a form of authenticity and local wisdom in buildings, while Arabic architecture as a complementary and additional component. This research was, therefore, conducted to optimize the maintenance factor in the mosque building to ensure it functions properly and sustainably towards serving as a historic worship place for future generations. Data were collected using questionnaires distributed to the congregants or users of the mosques and analyzed through optimization using a dynamic program based on the level of importance. The results showed seven maintenance factors including the complexity of construction and design, serviceability, building durability, security and safety, aesthetics of the building, user comfort, and maintenance capability. Moreover, the optimization process prioritized the ease in construction work, stability of the construction, durability against structural damage to the building, use of non-hazardous materials, aesthetics of the building, the comfort of indoor and outdoor spaces, and ease of maintenance. These are expected to be the focus of the mosque manager in maintaining the authenticity of the building components. This, therefore, means the Ampel Mosque building can be maintained as a religious tourism destination at the national and international levels in order to ensure its historical value is sustained while the local and national economy is improved.

“…This is seen in the use of non-professionals in construction work, the use of sub-standard materials, shoddy work, and the non-compliance and enforcement of building code specifications by clients, contractors, and regulatory bodies for selfish reasons. [4]. Therefore, in order to alleviate the frequent occurrence of collapse of concrete structures, new materials with enhanced load-bearing and weathering properties are being investigated.…”
