One of the least studied parts of a tall building life is its end-of-life scenario. Despite not that many cases of demolitions occurring in the past, many buildings are now approaching the end of their service life and the dilemma between their renovation or demolition is heating up. This is the subject of the CTBUH Research Study "A Whole Life Cycle Assessment of the Sustainable Aspects of Structural Systems in Tall Buildings" sponsored by ArcelorMittal.

With the Singer Building in New York, still representing the tallest building ever dismantled voluntarily (thus excluding the WTC Twin Towers collapsed during the terrorist attacks of  in 2001) new research is needed on this field. The Singer Building, which stood at 189 meters and it was demolished in 1969, thus with the use of technologies and methods that are not applicable any more.
One of Taisei's famous Top-Down demolitions in Japan
CTBUH has engaged the support of three world leading demolition firms (Taisei, Despe and Brandenburg) to provide with a description of the newest technologies for the dismantling of tall buildings and the development of a demolition plan for some of the tall building scenario being studied for the “A Whole Life Cycle Assessment of the Sustainable Aspects of Structural Systems in Tall Buildings” research.
