Abstract
The construction industry is responsible for 50% of the solid waste generated worldwide. Governments around the world formulate legislation and regulations concerning recycling and re-using building materials, aiming to reduce waste and environmental impact. Researchers have also been developing strategies and models of waste management for construction and demolition of buildings. The application of Building Information Modeling (BIM) is an example of this. BIM is emergent technology commonly used to maximize the efficiency of design, construction and maintenance throughout the entire lifecycle. The uses of BIM on deconstruction or demolition are not common; especially the fixtures and fittings of buildings are not considered in BIM models. The development of BIM is based on two-dimensional drawings or sketches, which may not be accurately converted to 3D BIM models. In addition, previous researches mainly focused on construction waste management. There are few studies about the deconstruction waste management focusing on demolition. To fill this gap, this paper aims to develop a framework using a reconstructed 3D model with BIM, for the purpose of improving BIM accuracy and thus developing a deconstruction waste management system to improve demolition efficiency, effective recycling and cost savings. In particular, the developed as-built BIM will be used to identify and measure recyclable materials, as well as to develop a plan for the recycling process.
Highlights
Sustainable waste management has become one of the vital environmental issues and the construction industry is responsible for 50% of the solid waste generated worldwide (Commonwealth Commonwealth of Australia, 2011)
Of the 53.1 million tonnes of waste generated in Australia in 2010–11, 14.5 million tonnes or 27.3% came from the construction and demolition (C&D) sector in 2010–11 (Australian Bureau of Statistics, 2014)
Australian governments have formulated legislation and regulations, such as ‘Construction and demolition waste guide –recycling and re-use across the supply chain,’ which is one of the documents produced by the Department of Sustainability, Environment, Water, Population and Communities, aiming to maximise waste reduction in the construction industry
Summary
Sustainable waste management has become one of the vital environmental issues and the construction industry is responsible for 50% of the solid waste generated worldwide (Commonwealth Commonwealth of Australia, 2011). Australians generated approximately 53.1 million tonnes of waste in 2010–11 (Australian Bureau of Statistics, 2014), an increase of 21.1% from 43.8 million tonnes of waste in 2006–07 (Australian Bureau of Statistics, 2010). This indicates that the volume of construction and demolition waste is continuously increasing over this period. The contributions of recycling and re-use of building material are significant in reducing waste and environmental impacts. Australian governments have formulated legislation and regulations, such as ‘Construction and demolition waste guide –recycling and re-use across the supply chain,’ which is one of the documents produced by the Department of Sustainability, Environment, Water, Population and Communities, aiming to maximise waste reduction in the construction industry. The State of NSW and Environment Protection Authority (2014) reproduced an avoidance and resource recovery strategy 2014–21 and have set a new target to increase recycling of construction and demolition
