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.

“…The approach was qualitative as the inductive approach. Other studies are also using this technique to compare available content in the existing state of the art and practice, including assessment techniques for BIM skills [11], enforcement procedures for environmental laws [12], and optimization techniques for rehabilitating water distribution networks [13]. Twenty (20) BEPs were selected and gathered for analysis to develop the BEP framework.…”

Building Information Modelling (BIM) is a process supported by technologies involving the development and management of 3D digital information model representations of functional and physical of the design. To implement BIM in a project, BIM Implementation Plan or BIM Execution Plan (BEP) needs to be developed as a planning and monitoring strategy document. Several BEPs have been developed around the world since 2010. However, a BEP should be tailored to the type of project, stakeholder requirement, and project objectives because a comprehensive BEP is a key factor for BIM implementation success. Also, a proper BEP helps stakeholders understand and achieve the underlying objectives in using BIM. In other words, understanding the strategic framework of BEPs is important. Hence, this study identifies and compares the key elements in existing BEPs. To accomplish that aim, twenty BEPs were identified and analysed. This study provides a benchmarked reference for industry players on existing BEPs. Through a clear description, all parties can understand the project objectives, work process, roles and responsibilities, information need and deliverables requirements in a BEP. Researchers can use the findings for further development and improvement of existing BEPs. Understanding BEPs will ensure better BIM implementation in practice.
