Building Information Modeling (BIM) is one such technology that can be utilized to achieve this goal. BIM has now reached dimensions of 6D and even 7D, with 6D BIM being used for energy analysis and 7D BIM for facility management during the operational and maintenance period of a building. This paper aims to discuss patterns, gaps, and trends in the utilization of BIM for effective building operation and maintenance. Bibliometric data mapping was conducted using VOSviewer® software, and 219 scholarly bibliographic records from the Scopus database between 2009 and 2023 were analyzed. The results showed that the highest publication growth was in 2021, with 36 publications (16.44%). China published the most articles, with 74 (29.84%). Recent research reviews indicate that BIM can facilitate the O&M process of a facility, including maintenance and repair, energy management, and security. However, there are still many challenges related to the BIM 7D function, such as data interoperability issues and the need for a framework for using BIM. The study also examines the application of BIM 7D in Indonesia. Further research is needed to balance the utilization of BIM for facility management with its application for asset management.

This poses a significant challenge in the era of globalization. If construction continues with high carbon usage, climate change conditions in the coming years will likely lead to global warming of more than 1.5°C. One of the proposed agendas in the Indonesia Construction 2030 document is the promotion of sustainable development through the application of environmentally friendly building concepts. This paper aims to map the studies conducted on Green Roofs within the past 10 years and study their application in Sustainable Construction in Indonesia. The mixed method approach was used in this research. A total of 864 articles were gathered from the Scopus database, and a bibliometric analysis was conducted using the VOSviewer® application.

Therefore, it should be wise to perform a life cycle cost analysis to determine the cost of any category contained in a building project. The analysis also provide information to see how much the total cost incurred by a development project from initial to the future cost by implementing BS ISO 15686 part 5: 2008. The purpose of this study is to identify the cost proportion and make long-term plans of a university building in term of life cycle costing in the area of University of Atma Jaya Yogyakarta (UAJY), and make a comparison of life cycle cost for a period of 25 years of nine buildings. Results of the study show that there are three groups that make up the life cycle cost: the cost of development of the building, the operating costs, and the cost of maintenance and replacement.

Eighty-one foremen drawn from three main trades (31 bricklaying, 27 carpentry, and 23 steelfxing foremen) from 27 projects in high-rise building participated in this study. The foremen were asked to estimate time lost of craftsmen under their span of control. This lost time was estimated with respect to each of the identified productivity problems. Results indicate that craftsmen lose up to 26 percent of their time due to productivity problems, the severity of these productivity problems were then ranked using the basis of time lost. Agreement on productivity problem ranking amongst the three groups of foremen was evaluated using Kendall Concordance analysis. Finding of this survey was also compared with that from a craftsmen survey. Results indicate that main productivity problems are: rework, lack of material, absenteeism, interference, and lack of proper tools.
