INTRO: Incessant
collapse of buildings in Nigeria are due to professional incompetence, faulty
foundation, overload, change in structural design, fake or substandard
products, natural disasters, and age. The increasing spate of buildings
collapse in Nigeria inspired this post. The most macabre of the horrible
incidences was the September 12, 2014 SCOAN Church building collapse in Lagos,
Nigeria which claimed a total of 115 lives who were mostly South Africans. The
Church argued that the collapse was caused by an unidentified aircraft which allegedly
hovered over the building before it crumbled.
While the
unidentified aircraft theory remains contestable, the real reasons why
buildings collapse are hereunder discussed.
The
reasons for and causes of building collapse in Nigeria are as follows:
- Professional
Incompetence: Some of the civil
engineers parading the streets and offices for contracts are quacks, while
majority of them are self-acclaimed. They end up erecting buildings of
several architectural infractions. For instance, concrete before being
approved is supposed to have passed through three different stages called
batching, testing and curing. If a civil engineer hasn’t the full
knowledge of these processes, the resultant building is most likely to be
defective.
- Faulty
Foundation: Different forms of foundations are
designed for different types of buildings and lands. Sometimes, foundation
alone depending on the type of the land and building would need almost
half of the money for the building before it could pass for strength.
Civil engineers or even the owners of buildings try to cut cost and end up
erecting the building on a faulty foundation that in no distant time would
lead to a mighty collapse of the building.
- Overload: The
amount of loads that a building will carry are taken into consideration
during its construction. There are three types of loads that a typical
building must have to carry, failure of which, a tragedy will strike. These
loads are: dead loads, live loads and wind loads. Dead loads are the
materials used in constructing the building such as sand, cements and
irons. This type of loads is compulsory for every building. Live loads are
the things packed into the house such as people, household property and
the likes. And finally, just as the name suggests, wind load is the
pressure from the wind. Any building that receives loads beyond its
carrying capacity is bound to fall.
- Furthermore,
another reason for the frequent collapse buildings in Nigeria is
change in structural design. Cases
abound where original plans of buildings were jettison for a new one in
the middle of the construction process or during reconstruction, during
which time, more often than not, more floors were added. As a matter of
fact, the SCOAN Church collapse was allegedly caused by the change in the
original plan of the building, and the building like house of cards,
crumbled perhaps due to either of the resultant reason numbers one, two
and three above, or all of them.
- Fake
or Substandard Products: In a despicable
bid to make more money, manufacturers make fake and substandard products
which greedy civil engineers patronize for their selfish reasons. The
building material markets in Nigeria are awash with fake and substandard
products which are sold in their quantities for use in construction of
buildings. This explains to a large extent the incessant collapse of
buildings in Nigeria.
- Natural
Disasters: This is rare in Nigeria, unlike the
countries of Europe and America where earthquakes, cyclones, hurricanes
and the likes have brought buildings down. In Nigeria however, disasters
such as flooding and fire outbreaks have led to the collapse buildings.
- Age
of the Building: Many buildings collapsed in Nigeria
because they have outlived their span. It is the law of nature that
whatever goes up must surely come down. The high-rises in various cities
of the country must in one way or another come down in its time. The
Lagos State Government for instance, has been on demolition campaign,
bringing down old and rickety buildings in the State in order to avoid
impending dooms.
