Abstract

The rapid urbanization across the globe has increased the demand for environmentally sustainable construction materials, particularly concrete, which alone contributes to over 8% of global carbon emissions due to cement production. Addressing this environmental concern, this study aims to explore eco-friendly concrete technologies that can support the development of sustainable and resilient urban infrastructure. Utilizing a systematic literature review (SLR) method, this qualitative research synthesizes findings from peer-reviewed sources and policy documents published between 2018 and 2025. The study focuses on evaluating technological, environmental, and economic dimensions of green concrete innovations including geopolymer concrete, self-healing concrete, recycled aggregate concrete, CarbonCure technology, and ultra-high-performance concrete (UHPC). Findings reveal that these technologies offer significant carbon reduction potential (up to 90%), enhance durability, support circular economies through waste reuse, and extend infrastructure lifespan. However, challenges such as high initial costs, lack of technical standardization, and policy gaps, especially in developing countries like Indonesia, hinder their widespread adoption. The study recommends multi-stakeholder collaboration, smart urban labs for field testing, financial incentives, and integration of life cycle assessment (LCA) frameworks in urban planning as strategic pathways for implementation. The paper concludes that eco-friendly concrete technologies hold substantial promise for sustainable construction in modern cities and align well with national and global environmental goals. Their integration is essential for reducing emissions, improving efficiency, and building climate-resilient urban ecosystems.

Abstract

The rapid digital transformation of the construction sector has positioned Building Information Modeling (BIM) as a key instrument in improving efficiency, transparency, and collaboration in public construction projects. This study explores the policy strategies and challenges of implementing BIM within national-scale public construction procurement and execution in Indonesia. The main objectives are to analyze existing national policy strategies, identify key challenges hindering implementation, and propose strategic policy recommendations. The research employs a qualitative approach using a literature study method, synthesizing findings from academic journals, government regulations, and institutional reports published between 2019 and 2025. Data were analyzed using content and thematic analysis, categorized into three main themes: policy strategy, implementation challenges, and policy recommendations. The results show that Indonesias government has made significant progress in integrating BIM through regulatory enforcement, standardization initiatives, and capacity-building programs. However, implementation remains inconsistent due to uneven technological infrastructure, insufficient human resources, limited interoperability, and financial barriers among contractors. The study recommends developing a National BIM Roadmap, enhancing data management systems, strengthening BIM education and professional certification, and providing fiscal incentives to promote compliance. These findings highlight that effective BIM implementation requires not only regulatory support but also institutional collaboration and long-term investment in digital infrastructure and human capital.
