Cross-laminated timber (CLT) is a versatile and eco-friendly building material that may be utilized in a variety of applications. It is however rarely utilized on construction projects in Nigeria. Thus, the study sought to establish the level of adoption of CLT and identify key drivers to its adoption in the Nigerian construction industry in an attempt to keep up with the global trend of adopting more sustainable construction practices and materials. A survey research approach was employed to gather data from 137 construction professionals who were selected using the snowball sampling technique in Lagos and Ogun States, Nigeria. A structured questionnaire instrument was designed to gather data from the respondents. A combination of Microsoft Excel and the Statistical Packages for Social Sciences was the software used to aid data analysis. The statistical tools deployed for the analysis were frequency, percentages, percentage mean adoption, relative importance index, and ranking. The findings revealed that the top four highly important drivers for the adoption of CLT are aesthetics, prefabrication, lightweight, and cost competitiveness. Besides, the findings also revealed that CLT was mostly applied as partition walls, door leaves, shelving units, and countertops. The study concludes that CLT is not engaged in as many as 20 building areas and components. This indicates that the construction industry is yet to embrace the eco-friendly features of CLT in building projects. The study therefore recommends that practitioners should endeavor to employ CLT in the building areas and components where they are not engaged to fully optimize CLT’s eco-friendliness in building projects. This may be accomplished by conducting workshops, and trainings as well as domesticating the necessary technologies to fully harness its potential.

In the dynamic landscape of the construction industry, the demand for efficient and precise project design methodologies has become paramount. Traditional approaches often struggle to cope with the complexities of contemporary projects, leading to delays, errors, and inefficiencies. This paper explores the evolution of parametric design methodologies, specifically focusing on the revolutionary TemesistCAD software developed to automate and optimize the modeling processes for warehouse and rack systems. Parametric design, characterized by dynamic adaptability through interconnected parameters, is showcased as a paradigm shift from labor-intensive conventional methods. The paper details the methodology of parametric design and its application in diverse industrial contexts, including Back-to-Back Racking, Mezzanine Racking, Radio Pallet Shuttle, Drive-In Racking, and Rack Clad Building Systems. It introduces the innovative TemesistCAD software, rooted in parametric principles, designed to streamline project workflows, reduce errors, and enhance precision in warehouse system designs. The software's application in various industrial scenarios is illustrated, emphasizing its versatility and effectiveness. When compared to other software in the warehouse and racking systems design field, TemesistCAD distinguish with its excellence in project design, manufacturing drawing preparation, and automated material takeoff generation. Its emphasis on parametric modeling not only addresses intricate design needs but also enhances accuracy in cost estimation and materials planning, ultimately optimizing workflow efficiency and minimizing project completion time.

The construction sector is one of the cornerstones of economic development around the world, and it is the small and medium sized construction companies working in this sector that are the driving force behind this economic growth. While many factors affect the project performance of these companies, one of these factors is thought to be the mental health status of the workers. In this context, the aim of this research is to examine the mental health disorders of workers in small and medium sized construction companies. The research aims to evaluate various demographic factors that may affect the mental health of workers and to suggest appropriate strategies. The study was carried out using a quantitative method and the data was obtained from surveys conducted among Turkish construction workers in SMEs. The survey form, consisting of a total of 31 questions, was administered to 216 randomly selected construction workers in SMEs. As data analysis methods, ANOVA statistical methods and t -tests were used to examine the relationship between mental health disorders such as depression, anxiety, and stress and demographic variables. It was found that the participants' living area affected the group average level of depression, but did not affect the group average levels of stress and anxiety. Finally, it was found that the depression scores of the participants living on the construction site were higher than those of the participants living in the apartment. It was also found that the chronic illness status of the participants affected the group average level of anxiety, while stress and depression did not affect the group average level. We also found that the anxiety scores of participants with chronic illnesses were higher than those of participants without chronic illnesses.

Potable water quality is crucial for society's well-being. Advanced devices and systems and a more specialized examination of quality parameters have improved the water quality in treatment plants. However, the property of the water may change for many reasons, such as pollution injection, water age, and system facility condition, and it may not have the same quality as the water released from the treatment plant. Due to the widespread nature of distribution networks, any contamination in water can quickly be distributed among consumers and cause irreparable damage. As a result, it is essential to preserve water quality until it reaches the final user. Leveraging new technologies and digitalization is the only solution to control and manage these massive and complex infrastructures. Digital twin (DT) is a trend word nowadays that is gaining more popularity. Digital Twin connects the physical infrastructure with the hydraulic model through two-way communication using numerous sensors installed inside the distribution network. Although previous studies have focused on the applicability of digital twin technology on water distribution network, they have failed to consider the potential impact of leveraging digital twin capabilities on water quality management. this article reveals the significance of integrating real-time demand data in hydraulic model to prevent water aging in the system by optimizing water level in tanks and pumps working hours based on network real demand and the role of digital twin for this approach.

Industrial plant construction projects are inherently complex, often involving numerous stakeholders, detailed technical specifications, and strict deadlines. Delays in these projects can have a significant impact on financial and operational aspects, including budgets, completion timelines, and overall plant efficiency. While previous research has primarily focused on civil and residential projects, there is a critical need to understand the specific factors causing delays and disputes in industrial plant construction. This study addresses this gap by examining a thermal power plant project in Turkey. A detailed case study analysis was conducted to investigate 12 work packages that had been subject to disputes between the Employer and the contractor. The methodology involved a comprehensive delay analysis with the objective of identifying the root causes of these disputes and delays. The study's key findings indicate that the late submission of design documents, project design changes, inadequate planning and poor communication were major contributors to delays. The study offers practical recommendations for improving project management practices, refining contractual agreements, and enhancing risk mitigation strategies. The findings have significant implications for stakeholders in industrial plant construction, offering strategies to mitigate delays and foster better collaboration between employers and contractors. This research contributes to the field by emphasizing the importance of minimizing delays and disputes through proactive risk management and effective communication to achieve project success.
