Student Section: ABOUT CIVIL ENGINEERING – By Karthik B. Patil, 8th B section Department of Civil Engineering

Civil engineering is the oldest and one of the most versatile branches of engineering. Every

structure that we see around today is a creation of civil engineering. Learn more about this

fascinating discipline.

Civil engineering is the oldest and broadest engineering discipline among all the engineering

fields. The field deals with the planning, designing, and construction of buildings and various other

structures. From huge dams to sky high buildings, from suspension bridges to offshore drilling

platforms, every physical concrete structure comes under civil engineering.

The usage of civil engineering dates back to the ancient times. Most of the seven wonders,

including Egyptian pyramids and the Taj Mahal, are the creation of flawless civil engineering skills.

Some of the world’s oldest civilizations such as Harappa and Mohenjo-Daro are also the product

of immaculate civil engineering. After all, how can one ignore the magnificent architecture of

Rome’s Coliseum or the unique design of the great Eiffel tower?

Sub-Branches of Civil Engineering

Civil engineering is the most diverse field of all the engineering branches. Technically speaking,

civil engineering is the creator of the whole world’s infrastructure. Structures such as tunnels, dams,

sewers, bridges, highways, canals, industrial plants, residential buildings, railway lines, airports etc

come under the category of civil engineering. Moreover, as the population of the world increases

and the technology becomes more advanced, the need for better infrastructure will increase

around the world. Civil engineering continues to cater to these needs in all the sectors and

aspects of human life.

The need for infrastructure has increased by leaps and bounds in each and every sector. In order

to concentrate and manage the construction process in each sector, the field of civil engineering

has been divided into various sub-disciplines. This means that on the basis of applications, the

stream of civil engineering has been segregated into several branches to make the construction

process easier and more manageable. Some of the main branches include – bridge engineering,

construction engineering, coastal engineering, geotechnical engineering, environmental

engineering, transportation engineering, surveying etc.

Application and Process

An ideal process of civil engineering will include the construction of a concrete structure right from

the planning to the maintenance of the structure even after it is made. Civil engineers are the

professionals who perform the functions involved in a construction process. They plan, design and

analyze each and every part of the structure before starting the actual construction process.

Designs of all the parts of the building along with precise specifications are drafted on drawing

sheets prior to the construction process. A study of various forces that can act at each of the

building corners is made and on the basis of that further modification in the design is done. Even

the minutest corner of the planned structures is scrutinized to check the amount of stresses and

strains that might arise when the structure is built or in the process of making. Apart from this, the


8

Vol. 1 | Issue 2

structures are also provided with tolerance levels to adjust deviations due to wind, seismic

activities, or natural calamities. These tolerances allow the building to resist the natural forces and

thus stand strong without being impacted.

Thus civil engineering deals with setting up reliable structures with guaranteed longevity. Also, with

an increase in awareness towards renewable sources of energy, the applications of civil

engineering have also increased. Environmental engineering, a sub-branch of civil engineer,

deals with constructing structures that have low impact on the environment and leave no carbon

foot prints. Environmental engineering also deals with creating structures on both onshore and of

shore sides in order to make efficient and environmentally friendly sources of energy. Some of

these applications include various methods to purify the contaminated air and water, utilizing

solar energy, generating fresh water, utilizing wind and water energy, and protecting the marine

environment.

Civil engineering is becoming more and more diversified with the increase of applications.

Moreover, the guidelines of constructing structures have also become more stringent, stressing

issues such as human safety and resistance to natural and man-made calamities.

GLOBAL POSITIONING SYSTEM (GPS) -AKASH.K.S & NISHANTH REDDY P, VI sem A section.

One hazard of human existence is being geographically lost, which can sometimes mean

the difference between life and death. The ability to know one’s position was considerably

enhanced on February 22, 1978, when members of U.S Air Force (USAF) Space Division based in

Los Angeles, California launched the first NAVSTAR (Navigation Satellite with timing and ranging)

satellite in the global positioning system (GPS).

The GLOBAL POSITIONING SYSTEM is a space-based navigation system that provides

location and time information in all weather conditions, anywhere on or near the Earth using

various GPS receivers. Gps receivers provide location in latitude, longitude and altitude.

In 1956 the German-American physicist FRIEDWARDT WINTERBERG proposed a test of

general relativity-detecting time slowing in a strong gravitational field using accurate atomic

clocks placed in orbits of artificial satellites. Thus the time determined by this test was 38

microseconds faster per day than the time on Earth. After this test two American physicists

WILLIAM GULIER and GEROGE WEIFFENBACH, at APPLIED PHYSICS LABORATORY (APL) launched

SPUTNIK 1,but due to Doppler Effect they could not pin point the location of the satellite, this

marked the base for the design of GPS. Later in 1970s, the ground based OMEGA navigation

system, based on phase

comparison of signal transmission

from a pair of stations, became the

first Worldwide radio navigation

system. Limitations of these systems

drove the need for a more universal

navigation solution with greater

accuracy. Owing to these

limitations the U.S began the GPS

project gathering ideas from its

several predecessors, including a

number of classified engineering

design studies from the 1960s.

The space segment of GPS consists


9

Vol. 1 | Issue 2

of a constellation of twenty-four satellites based in six different orbital planes at an altitude of

20,000 kilometres. Each satellite circles the planet twice in twenty-four hours and travels at a

speed of 3.89 kilometres per second. Each satellite weighs about 1,000 kilograms and is 5.25

metres long with his SOLAR ARRAYS extended.

Each GPS satellite has an inclination of 55 degrees with respect to EQUATOR, which means it flies

to a maximum height of 55 degres north latitiude and 55 degrees south latitude during its orbits.

The ground segment of GPS consists of RADAR stations that monitor the satellites to determine

the position and clock accuracy of each satellite. The location of these ground stations are as

follows:- Hawaii,Ascension Island, located in south Atlantic; Diego Garcia,located in the Indian

Ocean;Kwajalein,part of the Marshall Island of the Western Pacific ;and Schriever Air Force Base,

Colorado. The stations are staffed continously to ensure that GPS broadcasts the most accurate

data possible.

PRINCIPLE OF WORKING:-GPS works on

a very basic principle i.e.. intersections

of spheres.GPS makes use of multipe

satellite for determining the location

with more accuracy. If the GPS receiver

calculates distances from only one

satellite, it could be that excat distance

from the satellite in any direction.If there

are three satellites, then they form three

spheres then the location of the GPS

user is determined by the point of

intersection of three spheres.

Imagine a GPS receiver standing somewhere on Earth with three satellites in the sky above the

receiver i.e.. BS1,BS2,BS3 as shown,then the excat position of the receiver is given by point A(which

is the intersection of three spheres).

SOME APPLICATIONS OF GPS:-

GPS is extensively used to track Millitry operations and intelligence applications.

GPS is used for the preparation of 3D TOPOGRAPHICAL maps.

GPS is used to carry out survey in hazardous envirronment,sloppy regions.

GPS is also used by civilians for tracking purposes i.e..to locate the position of the civilians.
