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.
