“…Additionally, this study sought to emphasize the relative importance of the challenge rather than present the population's overall perception of the variables. This objective is consistent with other published work, such as identifying main factors for design-build implementation in public projects [21,22] and digital construction adoption in post-conflict low-income nations [23]. Therefore, the sample size is deemed sufficient.…”

While concrete recycling is crucial to protecting the environment, its implementation in practice is low in many countries. This study aims to highlight challenges to concrete recycling. To achieve that aim, the study objectives are (1) to identify the main challenges to concrete recycling in construction projects; (2) to compare the main challenges between small–medium enterprises (SMEs) and large enterprises (LEs); and (3) to determine the underlying groups among the main challenges. Potential challenges were identified through a systematic literature review of journal articles and semi-structured interviews with fifteen industry practitioners. Then, the identified challenges were inserted into a questionnaire survey and distributed to industry practitioners. Eighty-nine valid responses were collected and analyzed using the mean score ranking, normalization, agreement analysis, and factor analysis techniques. The analyses show thirteen main challenges to concrete recycling. The main challenges include increased project duration, lack of national programs, lack of comprehensive rules and regulations, increased project cost, low demand for recycled concrete, low cost-effectiveness of concrete recycling, and increased transportation cost. However, there is no consensus on the criticality between SMEs and LEs. For example, increased project cost is the main challenge for SMEs but is only middlingly ranked for LEs. Finally, the main challenges can be categorized into three interrelated groups: people and technical, legal and environmental, and economic challenges. This study contributes to the literature by analyzing challenges that hinder concrete recycling in practice. The findings allow researchers and practitioners to develop strategies to reduce concrete recycling rejection.

“…The normalized MSs were also calculated based on the different organization characteristics to identify the CPI for each group. Many researchers use this technique to identify critical factors, such as critical success factors for design-build implementation (Lee et al, 2021) and affordable housing (Adabre et al, 2020).…”

Purpose This study aims to investigate the interrelationships between COVID-19 pandemic impact and architectural, engineering and construction (AEC) organizations. To achieve that aim, the objectives are to: identify the critical pandemic impact (CPI) of COVID-19 on AEC organizations; compare the CPI between the different organization characteristics; and analyze the interrelationships between the CPI. Design/methodology/approach A systematic literature review of 519 articles and in-depth interviews with 40 AEC practitioners were carried out, yielding 12 COVID-19 impacts. Then, data on the 12 impact’s criticality were collected through a survey among AEC practitioners. In total, 127 valid responses were received and analyzed using mean ranking analysis, analysis of variance and Spearman’s correlation. The findings were also compared with pandemic impacts from prior works. Findings Five CPI exist among the 12 impacts, namely, “reduced construction productivity,” “reduced foreign investment in the construction industry,” “reduced demand on construction-related works,” “disruption in the supply chain” and “reduced number of public projects.” “Reduced foreign investment in the construction industry” and “reduced demand on construction-related works” significantly impact small-medium enterprises than large enterprises. Also, “disruption in the supply chain” and “reduced construction productivity” are recurring impacts in all countries compared. Finally, moderate relationships exist between “reduced foreign investment in the construction industry” and “reduced demand on construction-related works” and “disruption in the supply chain” and “reduced construction productivity.” Originality/value The findings can be used to prioritize available resources in developing short-term responses for COVID-19. Also, action plans can be developed to mitigate the CPI from recurring.

“…At the final stage, a pilot test was performed to ensure the validation of the questionnaires. This method of collecting the data is effective and was adopted by others in collecting data (Owusu et al , 2020; Alaka et al , 2017; Lee et al , 2021).…”

Purpose Sustainable water management has been a trending goal in the past decade. Non-revenue water (NRW) is one form of water loss that should be addressed to reach water sustainability. While rehabilitating water distribution networks (WDNs) is one way to decrease NRW, the process is often delayed owing to cost. Therefore, it is essential to provide decision-makers with cost-effective approaches to optimize WDN rehabilitation. This study aims to evaluate the cost-effectiveness of approaches for rehabilitating WDN from developing countries’ perspectives. Design/methodology/approach A systematic literature review was first conducted to identify different WDN rehabilitation methods and techniques to develop the questionnaire survey. This is followed by collecting questionnaire survey data in Malaysia and Egypt on the cost and effectiveness of the WDN rehabilitation methods and techniques. A total of 176 respondents were collected, 109 from Malaysia and 67 from Egypt. Then, the data were analyzed using mean score ranking with normalization technique and agreement analysis. Findings The results from the data analysis show that the cost-effective approaches are “programming,” “simulation,” “digital twin” and “supervisory control and data acquisition.” Additionally, the data from Malaysia suggest two additional cost-effective approaches: “zoning network” and “genetic algorithm.” Originality/value To the best of the authors’ knowledge, this paper presents one of the first studies that laterally compares the cost-effectiveness of existing and potential WDN rehabilitation approaches between different countries. There is yet a study that compared these WDN rehabilitation approaches. This comparison which is developed depending on the systematic review could be a reference for future studies or surveys which could be done on different countries in the future. The main findings of this paper can be a useful reference for decision-makers, especially those from middle-income countries, when looking into approaches for WDN rehabilitation. A better WDN rehabilitation supports NRW reduction, moving towards sustainable water management.
