Civil
engineering is a professional engineering discipline that uses knowledge of
calculus, mechanics, hydraulics and chemistry to develop the design,
construction and maintenance of infrastructure deployed in the environment,
including roads, railways, bridges, canals, dams, ports, airports, dams and
related structures. Civil engineering is the oldest after military engineering,
hence its name to distinguish non-military and military activities. Civil
engineers hold positions in virtually all levels in the public sector from the
municipal level to the government and in the private sphere from the small
independent consultants working at home until hired in large international
companies.

History of civil engineerin
Engineering
has been an aspect of life since the beginning of human existence. The earliest
practices of Civil engineering may have commenced between 4000 and 2000. C. In
ancient Egypt and Mesopotamia when humans started to abandon a nomadic
existence, creating the need for a shelter. During this time the transport
began to increase its importance, which led to the development of the wheel and
sailing.
Until the
modern age there is no clear distinction between civil engineering and
architecture, and the term engineer and architect suffered variations referring
to the same person, even intercambiándose.7 Building the Pyramids of Egypt
between 2700 and 2500 BC could be considered the first samples of large
constructions. Other historic buildings include the water management system of
Qanat, 8 Ictino the Parthenon in Ancient Greece (447-438 a.), The Appian Way by
Roman engineers or the Great Wall of China in 220 BC, or irrigation works in
Anuradhapura. Of all the ancient civilizations perhaps the most developed in
civil engineering was the Romans who pioneered the construction of a network of
roads, aqueducts, harbors, bridges, dams and sewers
In the
eighteenth century, the term civil engineering was coined to incorporate all
the engineering as opposed to civil use of military engineering (artillery,
ballistics, building defenses ...). In 1747 the school's oldest civil
engineering world is created, the École nationale des ponts et chaussées in
Paris, which continues today. The first self-proclaimed civil engineer was John
Smeaton who constructed the lighthouse Eddystone.4 6 In 1771 Smeaton and some
colleagues formed the Smeatonian Society of Civil Engineers, a group of
professionals who met daily to discuss their profession. Through these
meetings, professional societies we know today were formed.
CAREER GOALS:
The
objective of this event is to train Civil Engineers, senior professionals,
innovative and able to face the new challenges of modernity are endowed with a
formation that integrates knowledge of the scientific, engineering, management
and humanist, who harmoniously. Graduates of this career professional will be
able to plan, design, plan, build and manage works and civil engineering
systems, such as buildings, structures, roads, bridges, tunnels, canals, dams,
airports, harbor works, water supply systems and waste disposal and other
components designed to meet needs of society.
Additionally,
in their training, it seeks to promote skills development in the field of
management, leadership and teamwork, with an overview of the problems that
exist within an organization.
Branches of civil engineering
There are
several sub specialties and disciplines within the career of civil engineer and
most civil engineers work focused on a specialty. All have in common the need
for advanced mathematical and physical knowledge and the ability to solve
problems optimally.
- structural engineering
While
skyscrapers are buildings designed by architects, structural study usually
comes from a structural engineer that is an area of civil engineering.
- geotechnical engineering
Geotechnical
engineering estimate ensures resistance between particles of the crust of a
different nature, particle size, moisture, cohesiveness, and the properties of
soils in general, in order to ensure interaction with the structure of the
soil. Also makes the design of the foundation or support for buildings,
bridges, etc.
- hydraulic engineering
Besides the
study of dams, hydraulic engineering pipelines, canals, maritime events and any
structure that has to be affected by water are studied.
- Transportation engineering
The
transport engineering deals with the study of traffic, transport and mobility
of populations in order to increase comfort, reduce travel time and increase
safety on journeys of people.
- Materials Engineering
One of the
most important aspects of civil engineering is engineering materials. This
branch of civil engineering studies the properties of materials used in the
construction of civil works and hydraulic concrete, asphalt concrete, steel and
polymer, among many others.
- Roads and pavements
It is the
area of responsible civil engineering design and maintenance of roads and
structures. A dedicated Road Infrastructure and pavements engineer must have
knowledge in the following areas:
• Geometric
design of roads
• Design of
pavements (rigid and flexible) and its optimization.
• Materials
Engineering
Fields of application
Its scope
is broad. They would, for example, transport infrastructure:
• Airports
• Highways
• Roads
• Railways
• Ports
• Bridges
• urban
transport networks
Hydraulic works:
• Sewer
•
Waterwheels
• Channels
to transport drinking water or irrigation
•
navigation Channels
• potable
water piping
•
Hydroelectric
•
Depuradoras
• Dams
• Locks
• Docks.
• Dams
The structures that make up the earlier works:
•
Embankments
• Joints
• Works
containment field
• Tunnels
• Shoes
• Pillars
• Beams
• Boards of
bridges
In general,
civil engineering work involves a lot of people (sometimes hundreds or even
thousands) over periods ranging from a few weeks or months to several years.
Due to the
high cost of the works that are undertaken (think of the cost of a road or a
railway line) much of the work performed are for the state or for large
companies seeking the exploitation of an infrastructure long term. However,
their techniques are also applied to such works to the above but smaller scale,
as could be:
•
Containment of difficult terrain in the excavation for the foundation of a building.
• The
implementation of the structure of a building.
• The
design and implementation of systems for water distribution and sewage from a
small population (including the stations of potable water (ETAP), equipment
pumping stations sewage treatment plant (WWTP), etc..
• The
design and development of the streets of a small town
Moreover,
they are also responsible for a civil engineer:
• Planning,
design and control of urban transport systems, including the design of heat
exchangers and the creation of new lines or modifying existing ones.
• Adoption
of new transportation systems do not exist at that time, as lines underground
or light rail (more commonly known as tram).
• The
development and studies related to transport and logistics jobs.
• The preparation
of studies, plans and development projects, land and environmental management.
• Planning,
implementation and management of treatment plants or waste incineration and
landfills.
• Work
auxiliary engineering (quality control, laboratory testing, monitoring of
health and safety issues).
•
Maintenance of all previous
Thus, a
civil engineer is not limited to large infrastructure works, very rare due to
its high cost.

TOOLS, MACHINERY AND MATERIALS NEEDED IN CIVIL ENGINEERING:
Civil engineers build structures such as bridges, roads and waterways,
and for that they need to rely on very precise tools and know how to properly
handle them. Without technology and state of the tools, materials and the most
advanced construction vehicles, building structures would not be so sure. Civil
