Abstract: Purpose: Premature termination of construction contracts is a recurring problem that causes financial losses, delays, and strained stakeholder relationships. However, there is limited research on the specific causes of contract termination, particularly in Ghana, and practical solutions to prevent it are often overlooked. This study aims to investigate the pitfalls of contract termination in the construction industry and to propose effective prevention strategies based on empirical data. Design/Methodology/Approach: A quantitative research approach was adopted, employing a combination of purposive and random sampling techniques to gather data from 315 participants representing diverse roles within the construction sector. A structured questionnaire based on contract termination pitfalls was used, and data analysis involved descriptive statistics, factor analysis, and structural equation modeling (SEM) techniques. Findings: The study identified several critical factors influencing contract termination, including prompt payment by clients, adherence to contractual terms, competent supervision, and effective dispute resolution mechanisms. Through factor analysis and SEM, two main constructs emerged: Proactive Contract Management Strategies (PCMS) and Contract Termination Risk Mitigation Measures (CTRMM), each comprising specific indicators crucial for preventing terminations. Originality/value: This research contributes to the existing literature by providing empirical evidence of contract termination pitfalls and effective prevention strategies within the construction industry. The study’s multidimensional analysis approach, integrating quantitative techniques with Structural Equation Modelling (SEM), enhances the understanding of complex contractual dynamics and risk management in construction projects. Implications: The findings have practical implications for construction stakeholders, project managers, and policymakers. Implementing proactive contract management strategies such as clear payment protocols, rigorous quality control, and effective communication channels can significantly reduce contract termination risks. The study underscores the importance of integrating legal frameworks, innovative techniques, and managerial approaches in contract portfolios to enhance contract performance and project success in the construction sector.

Abstract: With the rapid development of urban construction, the demand for reliable data management systems is increasing. The Guangzhou Housing and Urban-Rural Development Bureau has recognized the necessity of data rights confirmation to enhance the management efficiency and security of monitoring data, which is crucial for ensuring the safety of construction projects. In response to the insufficient security and credibility of traditional foundation pit monitoring data during the certification process, this study proposes a design and verification scheme for foundation pit monitoring data certification based on blockchain technology. By designing smart contracts to achieve tamper proof and transparent sharing of data, we ensure the authenticity and reliability of monitoring data throughout its entire lifecycle. The experimental results show that the proposed scheme effectively reduces the security risks of foundation pit monitoring data during storage and transmission, and improves the efficiency and accuracy of data management. Meanwhile, based on the distributed nature of blockchain, the credibility of data has been enhanced, preventing the forgery and tampering of information. The design scheme of this study not only effectively realizes the certification of foundation pit monitoring data, but also provides new ideas for data sharing and security in engineering management, with important application prospects, especially in the fields of engineering safety, risk control, etc., which can provide strong data support for relevant decisions.

Abstract: This article studies the rupture of the Keur Bara KAIRE dike, located in the commune of Notto Diobasse in the department of Thiès in Senegal. The village is crossed by a stream which collects rainwater from the west to the east, following a natural slope. The overflow of this stream causes serious flooding, leading to the total cutting of the road and the isolation of the population. These floods had tragic consequences, resulting in two losses of human life. To regulate the water level, prevent flooding and protect agricultural and urban areas from overflows, the Senegalese authorities initiated the project to build the Keur Bara KAIRE dike in 2004, unfortunately the latter gave way in 2017. The geotechnical analysis was carried out on samples taken from various points on the site, revealing that the terrain is mainly composed of fine sand and the embankment is made with clayey sand. Morphometric and hydrological investigations highlight that the watershed of the Keur Bara KAIRE dike covers an area of 3.72 km², with a projected flow of 54.99 m³/s. The resizing of the dike revealed the following data: a length of 132 meters and a height of 3 meters. The spillway is 52.99 meters long with a reservoir height of 1.22 meters. The bay walls have a thickness of 50 cm and the embankments have a slope of ½ upstream and downstream. The stability calculation on the broken dike reveals a sliding safety factor (FSG) of 1.84 which complies with the standard and an overturning safety factor (FSR) of 0.13 which is not verified. The surface of the watershed which is equal to 3.72 km², also the smallest height of precipitation is equal to 234.9 mm and the largest 664.4 mm, the ORSTOM and CIEH methods for hydraulic calculations.

Abstract: Landslides constitute one of the principal perils in Nepal, particularly within its hilly and mountainous terrains, where a confluence of geological fragility and climatic extremities engenders precarious landscapes. Such hazards precipitate considerable loss of life and property. This investigation centers on the Aklesal Dablyang landslide in Baglung district, a potent menace to local infrastructure, agricultural domains, and human lives. By deploying a synthesis of geotechnical (laboratory-based soil analysis) and geophysical (Electrical Resistivity Tomography (ERT)) methodologies, the intrinsic properties of the soil and rock substrata within the landslide precinct were meticulously examined. The findings reveal that the landslide comprises predominantly loose colluvial deposits with elevated moisture levels, resulting in reduced shear strength and heightened failure susceptibility. The study accentuates the pivotal influence of hydrological phenomena such as surface runoff and groundwater seepage in aggravating slope destabilization. These results underscore the exigency for efficacious risk mitigation strategies to diminish landslide impacts on vulnerable communities. The Aklesal Dablyang landslide exemplifies the intricate interplay of geological and hydrological dynamics within Nepal’s complex topographical context. This research delineates the geotechnical and geophysical determinants of slope stability, highlighting the prevalence of loose colluvial deposits exacerbated by substantial moisture content, which attenuates shear strength and heightens vulnerability to mass movement. ERT analyses divulged a stratigraphy dominated by clayey sand interspersed with cobbles and boulders, which exhibit pronounced susceptibility to mass displacement during intense monsoonal precipitation—a phenomenon exacerbated by climate change. Anthropogenic interventions, including deficient drainage systems and substandard construction methodologies, further destabilize slopes by escalating pore-water pressure and diminishing soil cohesion. The study accentuates the imperative for integrative risk management paradigms, encompassing resilient engineering solutions, hydrological controls, and community collaboration, to bolster resilience against such geo-hazards.
