Framework for green construction assessment: a case study of government institution building project in Jakarta, Indonesia

Abstract

Construction industry plays an important role in establishing the infrastructure required for socio-economic development and directly contribute to economic growth Construction industry is associated with high energy consumption, resource depletion, and large amount of waste generation. Environmental impact assessments are necessary in order to identify effective measures in mitigating impacts associated with construction activities. Associated impacts must be quantitatively measured in order to determine the current status and thus. this shall help to gain more understanding in identifying mitigation actions. Assessment tools for evaluating the sustainability of construction during operational stage are crucial. "Green Construction" is construction projects which demonstrate the required sustainability level. Green construction involves a number of environmental and sustainability aspects. The aims of this paper are to present a practical case study of Green Construction project execution and to qualitatively evaluate its features based on "green" aspects and environmental impacts criteria. The importance of this research is to revolutionize and modernize the construction into a mare sustainable and industry by the implementation of "green" technologies, evaluation and monitoring tools, and adaptation of up-to-date international codes, standards, and policies. Detailed case study based on green construction aspects was conducted during project execution phases of a new multi-storey government institutional building in the Jakarta central business district. This project adopts Green Building and Green Site concepts in order to reduce potential environmental impact during the construction phase. In overall, this project has demonstrated most of green construction aspects. Prefabrication construction system, i.e. precast concrete elements and steel formwork system are proven to Significantly reduce the waste generated from concreting activities. Moreover, adaptation of relevant HSE international code & standards, audit and monitoring of environmental performance, support from top management, as well as awareness of environmental and social impacts are among many factors that contribute to implementation of green construction.
