The construction industry is a complex sector that encounters various difficulties, including housing shortages, productivity issues, labor scarcity, and sustainability. Construction companies must choose the most appropriate construction method for their clients and projects, which helps to address these concerns. The objective of this research is to examine the factors, challenges and mitigating measures related to construction methods adopted in building construction within Kathmandu Metropolitan City. To achieve this objective, a literature review was conducted to short-list factors and associated challenges as twenty-one and fifteen respectively. For the study purpose, one hundred and thirty questionnaires were distributed out of which one hundred and twenty-one valid responses were received. The study particularly focused on government engineers, designers, and developers as important stakeholders on identifying and ranking the major factors and challenges. Also, for analyzing the collected data SPSS software, Microsoft excel-2016 and Principal Component Analysis (PCA) were used. Through this study, twenty-one factors were identified and categorized in four components, which are: “Process optimization and safety”, “Creative ad expressive building approach”, “Sustainable construction ecosystem” and “Collaborative building component”. Also fifteen challenges were identified and categorized into three components, which are: “Safety and integrated system”, “Cost optimization” and “skepticism and conservative attitude of terminal users”. Subsequently, interviews were conducted with representatives to gain initial understanding of their preferences regarding factors, associated challenges with construction methods and their mitigating measures. Mitigating measures to overcome challenges associated with building construction methods were identified from Key informant interviews (KII). This study concludes that factors and challenges identified in this research are crucial not only in building construction methods adopted in Kathmandu Metropolitan City but also could be used as reference for other construction techniques used elsewhere which was validated by comparing several researches conducted in other countries. Such findings are significant for VII the construction industry performance improvement and to provide valuable insights for effective management. This study recommends to ease regulations, bylaws and provide trainings to masons in local level to effectively address the current factors and challenges associated with construction methods for buildings within Kathmandu Metropolitan City. The findings of this research could help the researchers to broaden their perspective and undertake similar studies encompassing other sector of construction industry.
