Abstract: Disagreements between construction parties to reach an agreed upon solution are common and frequent in the construction industry across the globe. Construction disputes waste time and resources and result in delays to the completion of projects. Clauses are added in contracts to facilitate the cooperation to reach agreements instead of legal escalations in court. Sometimes, these clauses cause more harm than good because of the provision of conflicting terms that culminate in legal conflicts, which invariably bring undesirable results to the projects. As the construction projects offer opportunities to contributed firms, they also increase the risk of disputes through disagreement or ambiguity within mutually agreed contracts. The selected dispute resolution method plays a significant role that mitigates the risk of escalation. The dispute to the level that reaches the legal courts and impacts the construction projects performance. This review sheds light on the major construction projects and contract dispute causes and recommendations.

Abstract: This paper investigates the torsional-flexural buckling behavior of thin-walled columns with single symmetric open sections. It focuses on deriving and solving the buckling equations for these specific column configurations. The analysis reduces the problem to a system of algebraic eigenvalue-eigenvector problems, identifying the critical buckling loads and modes. The buckling behavior is described by a system of three homogeneous differential equations, with two uncoupled equations, simplifying the analysis. Numerical examples illustrate that critical buckling loads decrease as column length increases, highlighting the relationship between length and stability. The results were validated through comparisons with established methods, including the differential equations method by Jerath (2020) and the equilibrium of deformed shape approach by Iyengar (1988), both of which show consistent results. This research contributes to a deeper understanding of the stability of thin-walled columns, providing essential insights for structural design and safety.

Abstract: The complex nature of slope engineering presents challenges in accurately predicting slope stability with traditional methods. Identifying the appropriate techniques for slope stability prediction is essential in mitigating the risks associated with slope failures. This study conducts a thorough analysis of two boosting machine learning models: Adaboost and LightGBM. By evaluating a wide range of hyperparameters, the research aims to discover the optimal settings for each model, ultimately leading to effective solutions.Six potentially relevant features were identified as key indicators for prediction: height (H), pore water ratio (ru), unit weight (Ƴ), cohesion (c), slope angle (β), and angle of internal friction (ɸ). The models were assessed using evaluation indicators such as AUC and accuracy, revealing that LightGBM significantly outperformed the Adaboost model, achieving an impressive AUC of 0.878 and an accuracy of 0.803. Furthermore, real-world engineering examples illustrate the effectiveness of LightGBM as a predictive tool for slope stability. Its enhanced capacity and efficiency in deformation prediction positions it as a leading instrument for accurate forecasting in this field. To deepen the understanding of these models, a comprehensive analysis of parameter sensitivity was also conducted, highlighting the most significant characteristics contributing to reliable slope stability predictions.

Abstract: This research explores the transformative role of smart materials in engineering, focusing on their integration into smart structures to enhance infrastructure resilience, sustainability, and efficiency. Unlike traditional materials, smart materials respond to environmental stimuli—such as temperature, pressure, or electric fields—enabling self-healing, adaptive behavior, and energy optimization. Key types, including piezoelectric, shape-memory alloys, electrochromic, thermochromic, and magnetostrictive materials, are examined for their unique capabilities and applications. Smart structures utilizing these materials exhibit advanced functionalities, from self-repairing concrete to energyharvesting systems, offering significant benefits in sustainability, cost-efficiency, and resilience against environmental stresses. However, challenges such as high initial costs, durability concerns, and integration barriers persist. This study highlights the current limitations and future directions for smart materials, aiming to foster more sustainable, adaptive, and long-lasting infrastructure solutions in the evolving landscape of civil engineering.

Abstract: Coagulation and flocculation are used in wastewater treatment to control the produced waste. Chemical coagulants have limited success in wastewater treatment because of their deficiency of consistency in meeting discharge requirements, high costs, handling, and disposal of huge volumes of sludge resulting from the increase of chemicals, and multiple operating problems. Instead of chemical coagulants, the natural ones can also be successfully used. Samples of wastewater were collected from the effluent of the grit removal chamber at the Belkas wastewater treatment plant, which is located in Egypt to study the enhancement of the performance of primary sedimentation. Experiments were conducted at various doses of Moringa Oleifera Seeds Powder (MOSP), Banana Peel Powder (BPP) and Mango Seeds Powder (MSP) using jar test equipment. Wastewater quality parameters were measured before and after treatment to evaluate the removal efficiency of turbidity, TSS, BOD₅, and COD. Using response surface methodology (RSM) to analyze the results of removal efficiency. Results showed that optimum operating conditions for (MOSP) at 720 mg/l and 45 min of sedimentation increased the removal efficiency of turbidity, TSS, BOD₅ and COD to 97.1 %, 99.3%, 94.67%, and 85.1% respectively. However, the optimum operating conditions for (MSP) at 480 mg/l and 45 min of sedimentation increased the removal efficiency of turbidity, TSS, BOD₅, and COD to 73.55 %, 62.57%, 59.87%, and 51.52% respectively. The optimum operating conditions for (BPP) at 105 mg/l and 45 min of sedimentation increased the removal efficiency of turbidity, TSS, BOD₅, and COD to 66.98 %, 57.93%, 58.76%, and 44.09% respectively. The removal efficiency will be reduced due to using doses of natural coagulants that exceed the optimum dose of each coagulant.

Abstract: The management and operation of water reservoirs particularly in regions susceptible to climate change and inadequate resource utilization requires careful consideration. This research focuses on the Alau dam situated in Northern Nigeria, a critical water source for the region. Despite its significance, the dam's performance faces challenges such as sedimentation, flooding, and insufficient adaptation to climate change. This study investigates the current state of management and operations at the Alau dam's reservoir emphasizing the frequency, challenges, and existing strategies. Utilizing a mixed-methods approach, including interviews, field observations, and analysis of water quality and water level, and aerial imagery. The study investigates the impact of these factors on the dam’s capacity, functionality, and structural integrity. Over time, sediment deposition has substantially reduced the reservoir’s effective storage capacity, leading to a misleading increase in surface area without corresponding water volume, thereby heightening the risk of overtopping and structural failure. Additionally, delayed and inflexible water release practices have exacerbated downstream flooding, while placing excessive hydraulic pressure on the dam's infrastructure, particularly the earthen embankments. The absence of a sediment management plan, coupled with inadequate maintenance, has further compromised the dam’s operational effectiveness and increased the likelihood of catastrophic failure. This study highlights the need for a shift toward adaptive management practices, including sediment removal, regular maintenance, real-time monitoring, and the incorporation of environmental flows. Recommendations include the implementation of a data-driven water release policy, infrastructure upgrades, secondary storage systems, and enhanced stakeholder engagement. These measures are critical for reducing flood risks, preserving downstream ecosystems, and ensuring the long-term sustainability and safety of the Alau Dam.

Keywords: Alau dam, reservoir management and operations, sustainable management, climate change, environmental concerns.
