    Numerical Investigations of Seismic-Resilient Techniques for Legged Fluid Storage Tanks Utilising Magnetorheological Dampers
    (Elsevier, 2024-08-19) Hosseini, Seyed Ehsan Aghakouchaki; Beskhyroun, Sherif
    Different energy-dissipating devices have been proposed in the literature to attenuate the destructive effects of base excitations over fluid storage tanks. These structures have numerous applications in strategic industries and their failure can result in environmental hazards and huge economic losses. Proposed techniques in the literature for seismic energy dissipation of fluid-contained tanks are mostly centred on passive and active control mechanisms. Semi-active control devices using materials with adjustable properties offer advantages of both active and passive systems while removing their drawbacks. In this paper, the performance of a Magnetorheological (MR) damper on the seismic response reduction of fluid storage tanks through the application of three different control strategies including H2/LQG, PID, FOPID, and two passive techniques, i.e. Passive On, and Passive Off has been investigated. Parameters of the semi-active controllers are optimally designed for each aspect ratio and the applied ground motion using the Hunger Game Search (HGS) technique and finally, the semi-active Clipping algorithm commands the voltage to the damper. The fluid-tank-MR damper system has been examined under three Far-Fault and three Near-Fault ground motions. Numerical simulations have demonstrated that depending on the aspect ratio, applied ground motion, and the control strategy, the MR damper can mitigate the peak relative displacements and absolute accelerations of the two major modes of the system, i.e the rigid and impulsive modes, up to 72% and 67%, respectively. This proves the efficacy of these dampers in reducing the maximum base shear and overturning moment, hence mitigating the damage risks in these structures.

    Lean Construction Enterprise Management: The Value and Potential of the Merit Game Simulation
    (The International Group for Lean Construction (IGLC), 2024-07) Stevens, Matt; Poshdar, Mani; Costa, Dayana B; Drevland, Frode; Florez-Perez, Laura
    A Lean Enterprise Construction-aligned learning game is an opportunity to meet the industry’s needs and wants. Competitive Simulation can offer such an alignment by using an online system as a medium to instruct. Learning three critical components: vocabulary, concepts, and processes, as well as game-based learning, allows students to acquire knowledge and skills through an interactive and entertaining learning experience to achieve the purpose of real-time teaching. As a result, many educators have adopted gamification in various disciplines in the tertiary sector to enhance learning and teaching. This paper will discuss applying the MERIT game to Lean Construction Learning through a case study within a leading Australian university. The case study incorporates the Merit Game and relevant organisational management content into an undergraduate construction management program. Its focus is Lean Enterprise principles and concepts. Overall, students reported a positive learning experience with higher order learning outcomes while identifying good practices incorporated into future delivery programs. The case study findings will inform academics and training professionals about the potential of the MERIT game, if tailored, for teaching Lean Construction at the enterprise level.

    Enhancing Lean Construction Through Innovative Technology: A Focus on Virtual Reality in Construction
    (The International Group for Lean Construction (IGLC), 2024-06-15) Bidhendi, Ali; Nahri, Zahra; Poshdar, Mani; Won, JW; Owais, Omar; Koohestani, Kayvan; B. Costa, Dayana; Drevland, Frode; Florez-Perez, Laura
    This study delineates the integration of Virtual Reality (VR) within Lean Construction, emphasising its application across the philosophy, principles, methods, and tools of Lean Construction. By conducting a systematic literature review, this research considers the utilisation of VR to enhance construction processes, specifically focusing on its role in mitigating waste, maximising value, continuous improvement, and respect for people. The investigation reveals VR's capacity to bridge the theoretical and practical aspects of Lean Construction, offering a novel perspective on its implementation. The results demonstrate VR's potential in advancing Lean Construction practices through its philosophy, principles, methods, and tools. Also, the utilisation of VR, particularly in SCRUM, Set Based Design and Visual Management, underlines a transformative potential for enhancing construction project efficiency and value. The paper concludes by highlighting the contributions of VR to Lean Construction, proposing actionable insights for practitioners and suggesting avenues for future research. This approach provides a comprehensive review for integrating VR in construction projects, aligning with Lean Construction for enhanced project outcomes.

    An Integrated Framework for Production and Environmental Waste Management in Construction
    (IGLC, 2024-06-15) Alazmi, Saleh; Abdelmegid, Mohammed; Sarhan, saad; Poshdar, Mani; Gonzalez, Vicente; B. Costa, Dayana; Drevland, Frode; Florez-Perez, Laura
    Lean construction has successfully developed and utilised several tools to minimise production waste generation in construction projects. In addition, sustainability research has contributed to improving the environmental performance of the construction industry by managing the impact of construction waste on the environment. Research on construction sustainability has been utilising some of the capabilities of lean construction tools to address environmental-related issues that are difficult to tackle using conventional approaches. Even though research in the Lean-Sustainability area has progressed over the last two decades, knowledge of Lean-Sustainability applications is still limited amongst industrial practitioners. A potential reason is the lack of an integrated approach combining lean principles and sustainability for construction applications. To address this limitation, this paper proposes a management framework that deals with both production and environmental wastes concurrently. The framework is developed by combining a lean process improvement method with an environmental management system approach. The framework is validated through interviews with experts in lean construction and sustainability to establish its theoretical contribution and practical applicability. Through this integrated waste management framework, this study contributes to the efforts of managing production and environmental wastes to deliver more efficient and environmentally friendly projects in the construction industry.

    From Concept to Concrete: Digital Twins Enabling Different Levels of Lean Construction
    (IGLC, 2024-06-15) Owais, Omar; Poshdar, Mani; Bidhendi, Ali; Jafar, Kamal; Sarhan, Saad; B. Costa, Dayana; Drevland, Frode; Florez-Perez, Laura
    The integration of Digital Twins (DTs) in Lean Construction (LC) represents a transformative approach to enhance collaboration, efficiency, waste reduction, and decision-making in construction projects. This paper explores the potential of DTs across different levels of LC through a comparative analysis method, aiming to establish a robust implementation foundation for lean organisations. Firstly, at the philosophy level, DTs foster collaboration, transparency, and respect for people by providing real-time data and virtual representations. They enable value maximisation, waste minimisation, and continuous improvement through visualisation, simulation, and data-driven decision-making. Besides, continuous improvement through monitoring and feedback loop. Secondly, at the principles level, DTs align closely with key LC principles such as value maximisation, continuous improvement, waste elimination, pull planning, continuous flow, and fast switch-over. By optimising processes, enhancing monitoring capabilities, and facilitating collaboration, DTs contribute to efficient project delivery. Thirdly, at the methods level, DTs complement LC methods such as Error Proofing, Value Stream Mapping, Target Value Design, and Last Planner System by facilitating real-time collaboration, visualising workflows, engaging stakeholders early, and providing error prevention capabilities. Overall, the strategic integration of DTs and LC thinking leads to improved project efficiency and value delivery, fostering ongoing innovation and improvement in the construction sector.
