Thedevelopment of the construction industry in Indonesia has been substantiallycontributing to the enhancement of the social and economic development of thepeople. However, its expansion has also become an issue, as the developmentmight be implicated in the abuse of environmental sustainability when thepractices of conducting the construction project abandon the rules and regulationsof sustainable green construction concepts. Therefore, this study attempted tointroduce a quantitative assessment tool called the Green Construction SiteIndex (GCSI) to evaluate the performance of an ongoing project to meet thesustainable green construction concept. The aim of this study was toinvestigate the effectiveness of GCSI as a quantitative assessment tool tomeasure the implementation of the green construction concept conducted byongoing projects. Data were collected by onsite direct observation, interviewswith key personnel, and project documentation review. Data were organized andanalyzed using descriptive elaboration. The results showed that three aspects,the Efficiency Index (IE), Productivity Index (IP), andAwareness Index (IA), were effective in assessing 10 ongoingconstruction projects, categorized as Non-Commercial Non-Residential Building,Commercial Residential Building, and Commercial Non-Residential Building. Theindex generated using GCSI, upon assessing 10 buildings, was 3.39 and fell intothe Good category with IE = 3.51, IP = of 2.86, and IA= 3.84. Another finding shows that the Project Organizational CommitmentIndex (POCI) to the indicator ofthe GCSI was 3.31 (Good category) with IPOL = 3.36, IPRO =3.49, and IPRAC = 2.75. The capability of the GCSI to identify threeaspects within a construction project simultaneously and comprehensivelysuggests the importance of its function as an effective tool that givesbenefits to not only the contactors, but also to the authorities that controlthe green construction?related performance. Therefore, the GCSI is expected tobe applied as a standardized reference by both the construction industries andregulating authorities. Despite its satisfactory findings, the GCSI needs to befurthered to achieve its reliability and validity to be adopted internationally. |
