SUSTAINABILITY APPRAISAL SYSTEM FOR CONSTRUCTION PROJECTS IN SINGAPORE

Abstract

In Singapore, there is currently no single sustainability appraisal system that adequately assesses a construction project’s sustainability performance. The impact of the construction industry on the environment has often been measured and assessed. However, the industry’s social and economic impact is often overlooked. Thus, the main objective of the dissertation is to develop a sustainability appraisal system through the introduction of suitable economic, social and environmental indicators for construction projects in Singapore. The dissertation adopts the ‘pillars’ concept of sustainability in trying to develop the appraisal system. To accomplish the objectives of this study, a conceptual framework based on PICABUE methodology is used to develop the sustainable construction indicators. Feedback from industry experts is then gathered to ascertain the practicability and feasibility of the appraisal system. The study found that the industry is not ready to undertake such an appraisal for construction projects. The main reason given was that stakeholders were unlikely to conduct the appraisal unless it is part of a government requirement. It is thus recommended that the government considers introducing a similar appraisal scheme in future. Further research on the topic of sustainability appraisal is also recommended so as to further streamline the appraisal procedure and hence gain industry acceptance.
