ASSESSMENT OF IMPLEMENTING SUSTAINABLE CONSTRUCTION PRACTICES THROUGH KAIZEN METHODS IN JIMMA ZONE

Abstract

The construction industry has recently faced increasing pressure to adopt sustainable practices, particularly within small , medium and large sized enterprises (SMEs) in developing regions like the Jimma Zone. Despite the recognized benefits of sustainable construction, the adoption of these practices remains limited due to various challenges. This research addresses this gap by evaluating the implementation of sustainable construction practices through Kaizen methods within SMEs in the Jimma Zone. The study aims to identify key factors influencing the adoption of these practices, analyze the challenges faced by SMEs, evaluate the impact of these factors on implementation, and assess the level of awareness and understanding of sustainable construction practices among SMEs in the region. The research employed a mixed-methods approach, combining quantitative and qualitative data collection methods to ensure comprehensive analysis. A structured questionnaire was distributed to a sample of 50 SMEs, with a response rate of 95.69% achieved, alongside semi-structured interviews conducted with 12 key informants. The survey data were analyzed using descriptive statistics and Cronbach's Alpha to ensure reliability, while related analysis was employed for qualitative data. The study focused on identifying the key factors, challenges, and levels of awareness that influence implementing sustainable construction practices through Kaizen methods. The findings revealed that while SMEs have a moderate awareness of sustainable construction practices, significant challenges—such as financial constraints, inadequate training, and limited managerial involvement—delay the effective implementation of Kaizen methods. The results suggest that these challenges significantly impact the successful adoption of sustainable practices. The study emphasizes the need for targeted involvement, including improved financial support, comprehensive training programs, and stronger managerial leadership, to enhance the adoption of sustainable construction practices. In conclusion, the research highlights the importance of addressing the identified challenges to successfully implement sustainable construction practices through Kaizen methods within SMEs in the Jimma Zone. This study provides valuable understanding for policymakers and industry stakeholders seeking to promote sustainability in the construction sector.
