Since the existence of humanity, the shelter has been at the top of the

basic needs. With the transition to settled life, permanent buildings

started to be built, and over time, the increase in the population has

brought the need for more housing. While single-floor and simple

buildings were built at first, multi-floor and complex structures

started to be made with the developing technology. Over time, these

buildings weaken against the loads and environmental events they

are exposed to and consume their lifetime.

In Turkey, located in the earthquake zone, risky buildings have been

identified, and an urban transformation process has been started

under Law No. 6306: the "transformation of areas under disaster

risk" published in May 2012. It has been foreseen that the demolition

of these risky and heavily damaged buildings, which are pretty

numerous, will take a long time with mechanical methods. This

period will bring along the discomfort given to the environment,

high costs, and unsafe working conditions. For this reason, the

applicability of different methods to reduce project duration and

cost has been investigated. As a result of these investigations,

demolition by controlled blasting technique, specified in the TS13633

standard of "Implementation Rules for Complete and Partial

Demolition of Buildings," which entered into force in October 2014,

has come to the fore.

In this study, the practitioners' steps in the demolition of buildings

by controlled blasting are described. In this context, building

demolition practices with the controlled blasting technique carried

out in our country were examined, the choice of demolition

technique and calculation methods were explained in the legal

framework, the parameters to be considered for a successful blast

demolition were classified, project steps are expressed, and solution

suggestions are presented.
