Developing a Model of Sustainable Construction for Condominium Projects in Developing Countries; Case of Indonesia

Abstract

Large-scale development of residential projects, including condominiums, is growing rapidly in developing countries. Despite their contribution to economic growth, the condominium also causes adverse environmental impacts. To address the problems, a sustainable construction paradigm has been introduced. Even though sustainable construction has been widely discussed, most studies focused on social and environmental aspects with little consideration for the economic objective of the business. This study aimed to develop a model to achieve three dimensions of sustainable construction for condominium projects. To identify the influencing factors and the interrelationships, a literature review was carried out and followed by a qualitative survey of 25 condominium projects in Surabaya, Indonesia. The variables consisted of resource consumption, waste, regulation, lean construction methods, sustainable materials, organizational capabilities, health and safety performance, resource efficiency, and life cycle cost. For data analysis purposes, a system dynamics approach was applied. The simulations reveal that the current practices are insufficient to achieve sustainable construction. To formulate sustainability policies, scenarios including the implementation of Modular Construction, tax incentives policy and a policy mix were employed. The results indicate that the scenarios could enhance sustainability in condominium projects. It can be concluded that the model can be used as a tool to improve sustainable construction for condominium projects in developing countries.

Influencing factors of sustainable highway construction

“…In order to maximize the likelihood of a project's efficacy and success, the project management technique is utilized as a strategy for handling project tasks in a systematic way. Projectbased companies can set standards for the implementation of activities and reap the benefits of optimal resource utilization by using and adapting the approach as formal processes [43]. Incorporating sustainability into project management represents a paradigm shift from the strategy that relies on predictable and controllable processes and outcomes, as opposed to merely adding to or altering current processes and standards.…”

An Evaluation of Scholarly Works of Tax Incentives in Indonesia

“…The government is attempting to reach its tax revenue goal by modifying tax incentives for 2020. On the one hand, the government needs tax revenue to help combat the Covid-19 outbreak, but on the other hand, it does not want to burden its citizens who are experiencing financial distress (Sutantio et al, 2022). In the midst of the Covid-19 outbreak, the government altered its policies regarding tax incentives through Minister of Finance Regulation Number 23 of 2020, which was subsequently replaced by Minister of Finance Regulation Number 44 of 2020, which later became a Ministerial Regulation, and was subsequently revoked and declared invalid by Minister of Finance Regulation Number 86/PMK.03/2020.…”
