Reader Response "4 Ways to Demolish a Building"
In the article “4 Ways to Demolish a Building”, Rodriguez
(2018) explains the various methods to tear a building down. The method used depends
on several factors but no matter which, safety is essential. The first method, by
implosion, is the most dramatic one. It is often used for large structures in
urban areas, and requires comprehensive planning for explosives to tear
buildings down. The next method uses the high reach arm, which is a demolition
tool attached to a base machine, and buildings are broken up from the top down.
The third method is the traditional, common wrecking ball which requires skillful
operators. This method creates environmental pollution. The last method is
selective demolition, or “strip-out”. It is increasingly popular as it allows
recycling and reusing of the materials for new structures. However, it lacks
efficiency. Based on the afore-mentioned points, it is apparent that building
demolition requires tedious planning and extensive preparation prior to the
actual activity, upon taking into consideration several factors relating to the
environmental, economic and social aspects.
First of all, the factors to be examined in the
environmental aspect are aplenty as demolition commonly causes environmental
pollution. With such big structures being torn down, there are inevitably major
potential impacts such as noise, dust, traffic implications and more
worryingly, waste. In the article “Deconstruction, demolition and destruction”
(2011), one key issue raised which is growing in significance is the large amount
of construction waste generated even from the simplest demolition. If
neglected, the waste generated is particularly problematic to Mother Nature.
Yet if proper planning is present, this “waste” can become a resource under the
concept of “urban mining”, which is constructive to the environment (Tran,
2017). Likewise, if the other types of pollution such as air and noise
pollution are not handled rightly, they can result in significant nuisance to
local and surrounding communities.
Secondly, the factors in the economic aspect are notable too,
making the outcomes of demolition difficult to predict. In “Making decisions on
the demolition or refurbishment of social housing" (2014), it states that estimating
the costs and impacts prior to the demolition process is full of complexity and
uncertainty. Also, after the demolition, many economic factors are consequently
greatly affected as well. One example is illustrated in the article “What is
involved in the building demolition process?” (2013). It states that the
removal of any building can “alter property values and property taxes in the
area”. It also adds that regardless of a small or big demolition project, “site
preparation is an important factor”. Hence, the planning and preparation step has
to be executed meticulously, to allow for adequate anticipation of ensuing
economic changes.
Lastly, with regards to the social aspect, massive
destruction of buildings often do go hand-in-hand with social transformation
processes. Although the post-demolition impacts in this aspect are often less
tangible and noticeable, I think that they are certainly as noteworthy as the after-effects
relating to the other aspects. The social costs to be taken into account
include direct and indirect ones (Tran, 2017). The former involves reparation
costs for damaged properties, costs to address communities’ concerns, and so on
and so forth. On the other hand, the latter refers to the social costs not
directly attributed to demolition itself, but rather to its aftermath. A
typical example of this is the healthcare costs due to high levels of air
pollutants caused by demolition. As such, the local communities will suffer
damages and discomfort if demolition activities are not well-planned and
prepared for. With this being said, general health and well-being are broad and
interdependent on varying factors, making the management of the social impacts
of demolition demanding.
All in all, the demolition of buildings is notorious to be
highly linked to environmental, economic, and social damages. Hence, abundant
attention needs to be given to the details in the groundwork prior to any
action taken. It is only with immense care and effort in the planning and
preparation stage, that the impacts of demolition in these aspects can be (and
should be) bettered. To conclude, there will always be a substantial amount of
embedded natural, financial and social capitals in the built environment, thus the
effort in planning and preparation of the demolition of a building is truly
staggering.

Hi Nicholas
ReplyDeleteYour reader response is relatively alright.
Your organization skills are good.
However, here are some points you might wish to review on:
Language:
- "Likewise, if the other types of pollution such as air and noise pollution are not handled rightly,..." you might want to consider changing the word rightly to properly
- "Although the post-demolition impacts in this aspect are often less tangible and noticeable, I think that they are certainly as noteworthy as the after-effects relating to the other aspects."
You might consider changing it to "Although post-demolition impacts on this aspects are often less tangible and noticeable, I think they are certainly comparable to the after-effects related of other aspects."
Best regards
