CHALLENGES FACED BY CONSTRUCTION SMALL-MEDIUM ENTERPRISES (SME) IN IMPLEMENTING SUSTAINABLE CONSTRUCTION

Abstract

The construction industry is one of the most resource-intensive industries in the world. Construction activities consume a significant amount of energy and water resources and, at the same time, generate a huge amount of waste and pollution. To curb any further degradation to the environment, the construction industry is moving towards Sustainable Construction. Successful implementation of Sustainable Construction will require the conscientious efforts of all players in the industry. However, it may not be possible for all to be involved in the implementation of sustainable practices due to the lack of ability and resources. This is especially so for small-medium sized construction companies which are often more concerned about their profit margins and capital turnover. Therefore, this study aims to assess the challenges encountered by construction SMEs in Singapore when implementing Sustainable Construction. The level of understanding and execution of sustainable practices on site would be investigated. From the literature review, it is found that construction SMES face challenges when implementing Sustainable Construction. The challenges are categorized into five main barriers, namely Financial, Time, People, Technology and Regulatory. In validating the barriers identified in the literature review, survey and interview are conducted and the results received are analyzed using statistical descriptive analysis method. The hypothesis is also proven using the one sample t-test. Finally, conclusions are drawn and recommendations have been proposed after the consolidation of survey and interview results analysis. Findings from the selected research method revealed that the lack of demand for sustainable features and practices to be incorporated into the work scope from the law and client is the paramount challenge to Sustainable Construction. The perception of reduced profit margin and lack of knowledge of sustainable practices and technologies also pose barriers to its implementation. It is recommended that the government can assist the SMEs in overcoming the challenges experienced. Together with guidelines and funding supports, the SMEs will be more motivated and have the incentive to engage in the implementation of Sustainable Construction.
