Civil Engineering is one of the oldest scientific disciplines known
to man. Early signs of professional engineering can be traced back to
4000 BC with the Egyptian and Mesopotamian civilizations. The Egyptian
pyramids till today remain a marvel to mankind, as to how in that day
and age such massive structures could be constructed. With such precise
calculations and engineering knowledge required they truly are wonders
of the world. In those times with no electricity or heavy machinery at
their disposal, getting huge rocks to move in their place with sheer
manpower is an amazing feat in itself. More examples of early evolvement
can been in the Indus valley civilizations where elaborate waterways
and structures were built.
Since then civil engineering construction has evolved
greatly. Today it has been further split into various multi disciplines
such as structural engineering, geo technical engineering,
environmental engineering etc. All these disciplines are core
specializations in them selves and require in depth study. We today have
heavy machinery at our disposal, which has helped the field evolve much
faster. With machines available,loads of much heavier weight can be
moved much faster.
The need for manpower has come down
drastically as machines take on the task of many men single handedly. We
have been able to build elaborate structures across difficult terrains,
which would not have been possible earlier. Precision work has
increased dramatically and has become increasingly easy. Machines of all
types such as excavators, compactors, rollers, bulldozers, measuring
instruments, cranes, dumpers etc. have been made available for different
construction activities.
Lets talk about some of these important machines that changed the construction industry further in brief:
Excavators:
An extremely important and widely used piece of machinery is used
across a variety of industries such as construction, mining, forestry,
demolition etc. The main purpose of the machine is to dig up earth fast.
The mechanism of the machine consists of a boom, stick, bucket and cab
sitting on top the main assembly also known as the house. Excavators are
also available in 360
