The construction industry contributes roughly 39% of the annual global CO2 emissions and is responsible for 35% of global waste generation in landfills due to the demolition of structures. To improve sustainability and material circularity in society, the construction and demolition sector holds a prominent position, particularly in recycling. With the release of EN 197-6 "Recycled Concrete", recycling of construction demolition waste (CDW) becomes more important. An essential step in recycling CDW is the efficiency of selective demolition techniques to maximize resource efficiency. However, major limitations of selective demolition includes increased duration of demolition, labor demand, and cost. This necessity underscores the importance of integrating selective demolition techniques with Building Information Modeling (BIM). This study aims to demonstrate the economic and operational and environmental perspective of selective demolition processes by using a BIM-based approach. A six-story residential building was modeled in Autodesk Revit to simulate the selective demolition scenarios. This study aims to compare the efficiency of two selective demolition techniques: a hydraulic breaker excavator and a mini excavator, from economic, operational, and environmental perspectives using a BIM-based approach. Assuming that the materials (concrete, brick) resulting from the demolition would be recycled and substituted, the amount of carbon emissions produced was calculated. The results showed that selective demolition increases recycling potential and contributes to the environment in terms of emissions, but it was concluded that selective demolition is not a viable option for contractors without incentives and subsidies.
