The implementation of environmental management system (ems) in construction project : investigation of success factors

The number of construction activities nowadays increased rapidly due to consequently urbanization and economic growth. The increased number of construction activities will cause adverse and huge impacts on the natural environment. Compare to other industries, it is far behind in the implementation of the Environmental Management System (EMS). This research aims to investigate the success factors and proposed a framework for the implementation of EMS in the construction industry. EMS introduced control strategies and have the proper management to address environmental issues caused by construction activities. This research reviewed some of the past studies related to EMS, the construction industry, and also sustainable development in construction projects. The data collected using purposive sampling. The data collection were done in two phases. The first phase of data collection was done to identify the success factors influencing the implementation of EMS. There were fifty (50) respondents from G1 until G7 contractors involved in the first phase of data collection. After that, the data were analyzed using the Relative Importance Index (RII) before the second phase of data collection took place. The result from RII established selected success factors to be included in the second phase of data collection. Questionnaires survey from the second phase of data collection were done to identify the interrelationship among each of the success factors. There were twenty-five (25) respondents who participated in this data collection. The questionnaires survey was designed based on DEMATEL questionnaires. DEMATEL was used to analyze the second data collection from respondents. By using the DEMATEL method, the interrelationship among each factor could be identified and a framework based on the relationship was proposed. The success factors underpinning the implementation of EMS are evidenced from the results of the framework. The success factors identified to have significant impact towards the implementation of EMS are management approach and technical aspects. Meanwhile non-success factors are organizational change and external and social aspects
