The 14-storey Radio Network building in Christchurch is set to be the first major structure in the city to be demolished by implosion.

The Worcester St building is set to be demolished on August 5, after the Canterbury Earthquake Recovery Authority (Cera) gave it the go-ahead.

Imploding a building involves detonating explosives placed in its structural connections so that the building collapses on itself within a matter of seconds.

The technique is mainly used in urban areas so that there is little damage to surrounding buildings.

Most buildings in Christchurch have to date been demolished through deconstruction, which allows materials to be reused.
