Summary Article (Draft #2)

In the article “4 Ways to Demolish a Building”, Juan Rodriguez (2018) states that there are many considerations to take before resolving the way to demolish a building, and the method used must be safe for the demolition crew and surroundings. He mentions 4 ways to demolish buildings. Firstly, implosion is a technique which uses explosives to demolish large structures in urban area and it requires comprehensive planning by the blaster crews before carrying out. Secondly, high reach arm method is used to tear down tall buildings from the top by operating machine arm. Thirdly, wrecking ball method demolishes buildings by swinging a heavy ball into the structure. The building size is limited by using this method. Moreover, it requires professional crane operator and will cause pollutions. Lastly, selective demolition is an environmentally friendly and cost saving method as it allows to recycle materials. However, it requires manpower and not efficient for light-framed buildings.

The article mentions that large structures are commonly demolished by using implosion technique in the urban areas. However, bring down a building by explosives is not applicable when the buildings are close together. Moreover, it will result in pollution to the city and may endanger the surroundings. Thus, high reach arm method is more suitable to be implemented in urban area.
