Acoustic technologies are popular for detection of leak detriments in water pipelines. However, problems false alarms, weak or difficult leaks, accurate pinpointing, and the high cost long-term monitoring remain prevalent. These issues demand a more sophisticated testing approach suitable real-world application. In particular, hydrophone technology has strong promise long-range high-attenuation conditions. existing review studies only cover methods holistically, with limited insight into...

Abstract This study aims to propose Micro-electromechanical System (MEMS) accelerometers for leak localization in the water distribution network and assess performance of machine learning models accurately estimating locations. Intensive field experimentation was conducted collect data model development. Machine algorithms were employed develop models, specifically artificial neural (ANN) support vector (SVM). Seventeen time-domain frequency-domain features extracted, feature selection...

Modular integrated construction (MiC) is a groundbreaking innovative technology, transforming the traditional into value-driven assembly of free-standing volumetric modules that are manufactured in factory and installed on site. Because MiC has been gaining attention local stakeholders, it imperative to assess feasibility, challenges, critical success factors (CSFs) for implementing Hong Kong. Existing literature disclosed CSFs from worldwide perspective, but investigation applicability...

Economic growth, social wellbeing, and infrastructure are strongly interrelated jointly contribute to national development. Therefore, evaluation selection of a road project direly need comprehensive sustainability assessment integrating holistic decision criteria. This study presents an elaborate life cycle sustainability-based tool, comprising framework, integration model, framework. In the first phase, (LCSA) framework for is established using mixed methods. second interviews conducted...

Fast-tracking the large infrastructure projects through overlapping design and construction levitates multifaceted risks aggravating project complexity critical to efficient planning. Traditional risk management largely treats independently ignoring their interrelationships, limiting understanding of strength nuclii project. To overcome this challenge, recent studies emphasize on employing dynamic assessment approaches. In line with these efforts, current study pertaining fast-track was...

Abstract This study reviews the state-of-the-art application of fiber optics in water distribution networks for leak detection and localization. The use oil gas sector has been well established; however, its potential pipelines is not evident owing to limited research. study, therefore, presents research developments localization using mixed methodology approach by integrating bibliometric systematic analyses. A scientometric analysis carried out analyze science maps (1) journal sources, (2)...

Abstract Effective water pipeline leak detection and localization can help practitioners save losses reduce pipe rehabilitation budgets. Different sensing technologies provide essential data aiding model development for predicting future leaks in the distribution networks. Solutions applying different to real networks are being developed real‐time collection, precise localization, reducing false alarms, continuous monitoring. Experiments of scales specifications have been conducted test...

Abstract Acoustic sensing technology is a familiar approach to detect leakage in urban water networks. Critical issues like false alarms, difficult leak locations, missed leaks, unknown site conditions, and high repair costs are still prevalent. The situation warrants developing more sophisticated efficient detection real Hydrophone based acoustic has strong promise for precision of leaks. However, AIoT using hydroacoustic data rarely reported. current study, therefore, proposes an...

Purpose The formal application of project risk management (PRM) in green building projects is still an emergent part management. purpose this paper to provide a conceptual PRM framework that increases the probability success by minimizing unexpected events. Design/methodology/approach This interprets related literature and uses opinion experts. It exposes some pertinent elements needed for structuring suggests mitigation actions high-ranked risks. also performs ex-post analysis on case study...

Integrating sustainability in the risk management process is an emergent problem, especially for efficient infrastructure delivery. For case of complex projects like public–private partnerships (P3), traditional practices offer a limited capacity to address long-ranging impacts on social, economic, and environmental fabric within around project boundaries. Although P3 are objective-based contracts, present models rarely delineate focused objectives. The relevant studies very scarce creating...

Delivery of sustainable buildings requires infusing sustainability criteria into project decisions. Hiring a suitable contractor and consultant for the delivery green is critical to ensuring procurement. Plus, introducing in prequalification process can improve stakeholder agreement on objectives help hire firms with appropriate experience delivery. Previous studies underline process-level inclusion procurement process. However, considerations are vaguely defined clear performance indicators...
