Introduction: The structure is like an animal's skeleton. It holds the building together. All construction elements have structure to some extent since they hold themselves and other neighboring parts. Traditional architecture did not separate enclosing structures. To illustrate, consider a pyramid or Romanesque cathedral. Even though we could eliminate some, all the …

In the existing literature, various modeling methods have been proposed, but two serious gaps remain untreated. First, a thorough field-scale measurement method for obtaining detailed information about different types of waste generated at various construction stages is still limited, resulting in inaccurate CWG data.

The generation of waste from C&D is much higher in Bangladesh compared to many developed and developing countries. The lack of public awareness, the absence of law enforcement, lack of community sensitization, and use of old technologies are the major causes of a higher amount of C&D waste generation in Bangladesh (Chowdhury et al., 2016b).The C&D …

total C&D waste in India was generated by buildings in just one year - 2013 - a humble 530 MT volume, 44 times more than official estimates. Imagine the scenario if waste generated from infrastructure projects such as roads and dams are added. Not surprisingly, in India, if the amount of C&D waste is determined, it will be higher than all other

Waste is generated at different stages of construction process. Estimated waste generation during construction is 40 to 60 kg per square meter. Similarly, waste generation during renovation/ repair work is estimated to be 40 to 50 kg per square meter. The highest contribution to waste generation is due to demolition of building.
