Challenges in Implementation of Safety Practices for Building Implosion Technique in India

Abstract

In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings. Despite its terminology, building implosion also includes the controlled demolition of other structures, such as bridges, smokestacks, towers, and tunnels. Every structure/building after its useful life needs to be taken care of as it poses a threat to the adjacent structures, and as the purpose of the building is fulfilled the structure should be demolished to construct a new structure. The techniques of selective demolition aim to maximize the recovery of reusable and recyclable building materials; however, a being labor-intensive and dilatory process it is mostly adopted in the Indian industry, as the building demolition activity is very complicated and involves high risk in terms of safety and cost. A minute deviation with respect to the timing of successive detonators, placement of detonators, and miscommunication can cause the demolition process to go for a toss. This paper deals with the various challenges faced by the major demolition techniques in India. The study also includes the precautionary measures regarding machinery or equipment, scaffolding, public safety, and worker safety. Various strategies for the demolition of waste have been reported in literature for implementing good practices for demolition of buildings.
