Excellence is an attitude that the whole of human race is born with. It is the environment that
makes sure that whether the result of this attitude is visible or otherwise. The well planned,
properly executed and evaluated industrial training help a lot in including the good culture. It
provides linkage between industry in order to develop the awareness of industrial approach to
problem solving based on broad understanding of process and mode of an organization. During
this period, the student gets their real firsthand experience on working in the actual environment.
Most of the theoretical knowledge that they have gained during the course of their studies is to
put to test here. Apart from this the student gets the opportunity to learn the latest technology,
which immensely help them in their career. This also benefits the organization as many students
doing their report perform very well and are here forth offered job in same organization.
I had the opportunity to have the real practical experience, which has increased my sphere of
knowledge to a great extent. Now I am better equipped to handle the real thing than anyone else
that has not undergone such training. During the training period, I learned how an actual report
progresses, what sort of problem actually occurs during the development of such reports. And
being in such a reputed organization, I had but the best exposure.

INTRODUCTION
Building construction is the engineering deals with the construction of building such as
residential houses. In a simple building can be define as an enclose space by walls with roof,
food, cloth and the basic needs of human beings. In the early ancient times humans lived in
caves, over trees or under trees, to protect themselves from wild animals, rain, sun, etc. as the
times passed as humans being started living in huts made of timber branches. The shelters of
those old have been developed nowadays into beautiful houses. Rich people live in sophisticated
condition houses. Buildings are the important indicator of social progress of the county. Every
human has desire to own comfortable homes on an average generally one spends his two-third
life times in the houses. The security civic sense of the responsibility. These are the few reasons
which are responsible that the person do utmost effort and spend hard earned saving in owning
houses. Nowadays the house building is major work of the social progress of the county. Daily
new techniques are being developed for the construction of houses economically, quickly and
fulfilling the requirements of the community engineers and architects do the design work,
planning and layout, etc., of the buildings. Draughtsman are responsible for doing the drawing
works of building as for the direction of engineers and architects. The draughtsman must know
his job and should be able to follow the instruction of the engineer and should be able to draw
the required drawing of the building, site plans and layout plans etc., as for the requirements.

INTRODUCTION TO BUILDINGS
A building is a structure with a roof and walls standing more or less permanently in one place,
such as a house or factory. Buildings come in a variety of sizes, shapes and functions, and have
been adapted throughout history for a wide number of factors, from building materials available,
to weather conditions, to land prices, ground conditions, specific uses and aesthetic reasons.
Buildings serve several needs of society – primarily as shelter from weather, security, living
space, privacy, to store belongings, and to comfortably live and work. A building as a shelter
represents a physical division of the human habitat (a place of comfort and safety) and
the outside (a place that at times may be harsh and harmful).
Different types of buildings
Buildings are classified based upon its occupancy and structure
• Residential Building
• Educational Building
• Institutional Building
• Assembly building
• Business buildings
• Mercantile buildings
• Industrial Buildings
• Storage buildings
• Hazardous buildings
• Residential Building: Buildings in which sleeping arrangements are provided with or without
cooking arrangement. It includes single or multifamily dwelling, apartments, lodgings,
restaurants, hostels, dormitories and hotels
• Educational building: These Include any building used for school, college, education
purposes.
• Institutional Building: these buildings used for different purposes, such as medical or other
treatment. They include hospitals, sanatorium, jails, and asylum
• Assembly Buildings: These are the buildings where group of peoples meet or gather for
amusement, social, religious, political, civil, travel and similar purposes. E.g. theatres, motion
pictures, houses, assembly halls, restaurants assembly halls.
• Business buildings: These buildings are used for transactions of business, for keeping accounts
and for similar other purposes.
• Mercantile building: These building are used as shops, stores, market for display and sale of
merchandise either wholesale or retail, office, shops, and storage services.

11. 4
• Industrial Buildings: These are buildings where products or materials of all kinds and
properties are fabricated, assembled, manufactured or processed
• Storage buildings: these buildings are used primarily for the storage or sheltering of goods,
wares or merchandise, vehicles and animals, grains
• Hazardous buildings: These buildings are used for the storage, handling, manufacturing or
processing of highly combustible or explosive materials or products
Classification based on structure
1. Load bearing Structure
2. Framed structure
• Load Bearing Structures: In this type of structures loads from roof slab or trusses and floors
are transmitted through walls to the firm soil below the ground .This type of structures are
adopted where hard strata are available at shallow depth. The structural elements like beams,
slabs rests directly on the walls.
• Framed Structures: Reinforced cement concrete structures are the most common type of
construction today. They consist of a skeleton of beams & columns. The load is transferred from
beams to the columns and column intern transfer the load directly to the sub soil through footing.
Framed structures are suitable for multi-story building subjected to variety of extreme loads like
compressive, tensile torsion, shear along with moment. • The open spaces in the skeleton are to
be filled with brick walls or glass panels.

12. 5
Types of Loads
Various loads are taken into account while designing the foundation of a structure.
1. Dead loads
2. Live loads
3. Wind loads
4. Earthquake loads
5. Erection loads
Dead Load: Dead load comprises of the weight of all walls, partitions, floors and roofs
including all other permanent construction in the building
Wind load: It is considered as basic wind pressure which is equivalent static pressure in the
direction of the wind • Wind pressure= k v2 • Where k= co-efficient, 0.006 • V= wind velocity •
Wind pressure always acts in the vertically exposed surface of the walls and columns.
Snow load: Actual load due to snow depends upon the shape of the roof and its capacity to
retain the snow. The load due to snow may be assumed to be 2.5 kg/m3 per cm depth of snow
Earthquake load: an earthquake load produced waves in every possible direction below
ground. As per intensity or scale of earthquake, jerks and shocks are acting on the earth. As per
the location of the building in the prescribed zone of earthquake coefficients of earthquake loads
are decided.
Live Load: Live Loads consist of moving or variable loads due to people or occupants, their
furniture, temporary stores, machineries.
Erection Load: All loads required to be carried by the structure or any part of it due to storage
or positioning of construction material and erection equipment including all loads due to
operation of such equipment, shall be considered as ‘erection loads

Elements of Building Construction Planning
Elementary Principles and basics of a building planning, layout of residential and industrial
buildings
Principles and building planning
• The term planning of a building refers to mean the arrangement of all the units of a building on
all the floors and at all the levels.
• There are certain general principles which as a engineer should bear in mind while planning a
building.
The general principles are
• Aspect
• Prospect
• Privacy
• Grouping
• Roominess
• Flexibility
• Furniture requirements
• Circulation
• Elegance
• Economy
• Sanitation
Fig.4.STAIR

20. 13
Aspect
• Aspect: different rooms of the buildings are placed and located accordingly to the functional
utility in such a way that maximum advantage of natural elements like sun, wind, can be
obtained. To obtain sufficient sunlight inside the room windows are placed in external walls
• Kitchen aspect: Kitchen should have window in east, because morning sun kills the germs. So
kitchen should have eastern aspect.
• Bed room aspect: Bed room is a unit of residential building generally used in night time, for
sleeping so evening sun rays, which are cool in nature should enter the bed room to create
cheerful atmosphere. So bed room should have western aspect, south-western or north-western
aspect.
• Drawing room aspect: It is a room which is used by the occupants for maximum hours of the
day. To achieve good sunlight it should be placed in south or southeast or north-east. Windows
should be provided in external walls
• Study room aspect: Windows in this room should be in northern side to obtain sufficient light
throughout the day. So aspect of this room is north.
• Verandah: there should be sufficient light in the above unit throughout the day so they should
be placed with opening in north-direction.
Prospect It is related with the views as seen of the outside from doors and windows in the
external wall. For pleasant atmosphere view of a garden, hill and a river, etc. is a good prospect.
Towards these objective doors and windows should be provided in the external wall of the
building. Undesirable views like a small nallah, slum area, drainage disposal unit, garbage
collection centers should be concealed by not providing windows in that direction
• Prospect of living room should be toward the main road to keep control on the plot. Prospects
of bed should be on the rear side of the building so that to avoid disturbance due to noise.
Privacy This is very important factor to be considered while planning both residential as well as
public building Privacy of one room from another in a building as well as privacy of the whole
building with other building should be achieved.
• The privacy of residential building as a whole can be achieved by planting trees, and by
providing entrance. Even the compound wall of required height can be constructed to provide
privacy of trespassers.
• Privacy in different rooms can be achieved by providing doors in such a way that minimum
view of room is seen when shutter is opened. Privacy is very important in bed rooms and wick.
And the view of bed room should not be visible from any other room.
Grouping: t is the arrangement of various rooms with respect to their functions, In case of
residential building to achieve maximum efficiency of the plan the grouping should be done as

21. 14
follows • Verandah should be the first unit after the entrance of the house • Living room and
dining room should be close next to verandah • Kitchen and dining should be close to each other
• Sanitary arrangements should be close to bed rooms. • Staircase should be approachable from
each room • Passages connecting various rooms should be well lighted and ventilated
Roominess This principle of planning is directly related to dimensions of the room. A
rectangular room is found more convenient as compared to a square room of the same size.
Hence length to width ratio should be 1.2 to 1 or 1.5 to 1 if the ratio is greater it will give a
tunnel effect to the room. Height of doors and windows, ceilings, floorings, color treatment also
affect the roominess of the building unit. Light color give effect of more space whereas dark
color makes the room look smaller. Height of ceiling should be low as more height gives a
feeling of a cave.
Flexibility Flexibility means a room which was planned for one function can be used for other, if
so required. If rooms are big enough and are having a minimum width of 3m are more flexible
and even the activities of various rooms can be exchanged.
Furniture requirement one of the most important requirement of a building planner, is to know
how much space is needed by each function in a particular building. The room sizes for a
particular function can be completed on the basis of permanent furniture's to be used in the room.
Hence while planning a building furniture arrangement must be shown.
Circulation: Circulation is the access into or out of a room. It is the internal movement inside
the building and the area earmarked for it.
• Circulation area should be straight, short, bright, lighted.
• Circulation should not affect the privacy of a room nor interfere with the utility space
• Circulation in a building is of two types
• Horizontal circulation and vertical circulation
• Circulation within a floor is called horizontal circulation
• And circulation between different floors is called vertical communication
Lighting It can be natural light as that obtained from the sun during the day or artificial light.
Adequate illumination is essential in day to day activities to execute the safety and comfort and
efficiency
• Good visibility is a must for accident prevention, comfortable watching and reading to reduce
fatigue, avert confusion, and efficient security.
Elegance Elegance refers to the planning of elevation and layout of the plan to give an
impressive appearance to the building. The proper width, height, location of doors and windows,

22. 15
materials employed in construction of exterior walls etc. create elegance. The result of elegance
is aesthetics of building.
Economy Building planning should be carried out in the financial limit of the client. An engineer
should know in advance, the client intends to spend for the building and accordingly material of
construction, finishing items, stage of construction should be suggested. By estimation proposed
amount should be derived and as per that progress should be followed to avoid delay in work
progress.
Sanitation: Provision for cleanliness, lighting and ventilation in sanitary units avoid growing of
bacteria's, and spread of diseases and give hygienic condition. In bath and w.c. glazed tiles and
dado should be provided on wall to maintain clean condition. The ventilator in bath, w.c. permit
sunlight and air collation to maintain hygienic condition. The flooring material s should be easy
to clean, skirting's should be provided in rooms. Bath tubs, w.c. , kitchen sink should be made of
ceramic material to maintain clean easily.

Building bylaws
• During planning and construction of any building, certain regulations are laid by Municipal
bodies, authorities, and other government departments as town planning so as to prevent
haphazard development of city such rules and regulations are called as building bylaws.
Objectives of Building bylaws
Building bylaws allow disciplined and systematic growth of buildings and towns and prevent
haphazard development
• Building bye-laws protect safety of public against fire, noise, health and structural failure.
• They provide proper utilization of space, hence maximum efficiency in planning
• They provide health, safety, and comfort to peoples living in the building.

MATERIALS USED
Stone: - The stone is always obtained from rock. The rock quarried from quarries is called stone.
Quarried stone may be in the form of stone blocks, stone aggregate, stone slabs, and stone lintels.
Here to be used as impact test, water absorption test, hardness test and crushing strength. It is
preferred according to SP27-1987.
Brick: - Brick is made up of soil and it is used to make the masonry structure Absorption test,
Shape and size test, Crushing strength test, Soundness test, Hardness test. The bricks be table-
molded, well burnt in kilns, copper- colored, free from cracks and with sharp and square edges.
Aggregate:- Aggregates shall comply with the requirements of IS 383. As far as possible
reference shall be given to natural aggregate. Aggregates are the important constituents in
concrete. They give body to the concrete, reduce shrinkage and effect economy. One of the most
important factors for producing workable concrete is good gradation of aggregates. For most
work, 20 mm aggregates are suitable.
Specific gravity of fine aggregate = 2.38
Specific gravity of coarse aggregate = 2.71
Cement:- The most common cement used is Ordinary Portland Cement. The type I is preferred
according to IS: 269-1976, which is used for general concrete structures. 53 Grade ordinary
Portland cement is confirming to 12269. Out of the total production, Ordinary Portland Cement
accounts for about 80-90 percent.
Fineness of cement = 8%
Standard consistency of cement = 31%
Initial setting time of cement = 36 min
Specific gravity of cement = 3.46
Water: - Water is an important ingredient of concrete as it actually participates in the chemical
reaction with cement. Since it helps to form the strength giving cement gel, the quantity and
quality of water is required to be looked into very carefully. Water used for mixing and curing
shall be clean and free from materials like oils, acids, alkalis, salts, sugar, organic materials or
other materials that may be harmful to concrete or steel. PH value of the water used in concreting
shall not be less than 6
Steel: - Steel is important ingredient of qualify structure and it is used to carry out the load
easily from the structure to column and it is having high tensile strength. It is preferred according

Colour Test:-The color of the cement should be uniform. It should be grey color with a light
greenish shade.
Strength test:-A block of cement 25 mm ×25 mm and 200 mm long is prepared and it is
immersed for 7 days in water. It is then placed on supports 15cm apart and it is loaded with a
weight of about 34 kg. The block should not show signs of failure. If cement is of sound quality
such block will not be broken easily.
Setting test:-A thick paste of cement with water is made on a piece of glass plate and it is kept
under water for 24 hours. It should set and not crack.
Tests on aggregates:-
Silt Content for Aggregate:-The permissible silt content in sand (fine aggregate) must not
exceed the values as specified in the standards. However, this method can only be used for
natural sand, it should not be used for crushed rock sand.
The apparatus required for this test is only 250 ml glass measuring cylinder.
The silt content determination by volume is done in the following manner:
 The glass cylinder is filled with salt-water solution (concentration of the solution will
teaspoon full of common salt for every 570 ml) up to 50 ml mark.
 Add sand until the level of the sand is up to 100 ml mark.

 Add further salt-water solution till 150 ml mark is reached.
 Place the palm on the mouth of the glass cylinder and shake it vigorously.
 Place the cylinder on hard levelled surface and tap it all round so that sand is leveled.
 Wait for three hours for silt to settle on top of sand.
 Measure the thickness of the silt layer and the height of the sand. The silt content can be
calculated as follows:
Silt (%) by volume = [(Thickness of silt layer/ Height of sand + Silt) x 100 %]
Sieve Analysis:-Sieve analysis is done to check the gradation of aggregate.
 The test is done as follow.
 Take required amount of aggregate sample (for coarse aggregate take approx. 2.5 kg and
for fine aggregate take 0.5 kg)
 Arrange the required no of sieves as per the contract or job requirement in a descending
manner. (i.e. keep the sieve having largest size opening at the top and the smallest size
opening at the bottom)
 Shake vigorously the sieve set for at least 2 minute.
 Then measure the weight of aggregate on each sieve and express it as the percentage of
passing.
Now compare these values with the recommended values to know whether it falls within the
range or not. If not falling within the desired gradation then take necessary action.
Fineness Modulus:-Fineness modulus is generally used to get an idea of how coarse or fine the
aggregate is. More fineness modulus value indicates that the aggregate is coarser and small value
of fineness modulus indicates that the aggregate is finer.
 Sieve the aggregate using the appropriate sieves (80 mm, 40 mm, 20 mm, 10 mm,
4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron & 150 micron).
 Record the weight of aggregate retained on each sieve.
 Calculate the cumulative weight of aggregate retained on each sieve.

32. 25
 Calculate the cumulative percentage of aggregate retained.
 Add the cumulative weight of aggregate retained and divide the sum by 100. This
value is termed as fineness modulus.
Compare the test value with the values given in the following table and you can get an idea about
how coarse or fine the sand is.
Only sand between FM 2.6 to 2.9 is considered suitable for nominal mix proportion.
Type of Sand Fineness Modulus Value
Very fine sand Below 2.2
Fine sand 2.2 to 2.6
Medium sand 2.6 to 2.9
Coarse sand 2.9 to 3.2
Very coarse sand Above 3.2

Tests on concrete:
Compressive strength of concrete:-The compression test shows the compressive strength of
hardened concrete. The compression test shows the best possible strength concrete can reach in
perfect conditions. The compression test measures concrete strength in the hardened state.
Testing should always be done carefully. Wrong test results can be costly.
The testing is done in a laboratory off-site. The only work done on-site is to make a concrete
cubes for the compression test. The strength is measured in Mega pascals (MPa) and is
commonly specified as a characteristic strength of concrete measured at 28 days after mixing.
The compressive strength is a measure of the concrete’s ability to resist loads which tend to
crush it.
Procedure of slump test for concrete:
 Clean the cone. Dampen with water and place on the slump plate. The slump plate should
be clean, firm, level and non-absorbent. Collect a sample of concrete to perform the slum
test.
 Stand firmly on the foot pieces and fill 1/3 the volume of the cone with the sample.
Compact the concrete by 'rodding' 25 times. Rodding means to push a steel rod in and out
of the concrete to compact it into the cylinder, or slump cone. Always rod in a definite
pattern, working from outside into the middle.
 Now fill to 2/3 and again rod 25 times, just into the top of the first layer.
 Fill to overflowing, rodding again this time just into the top of the second layer. Top up
the cone till it overflows.
 Level off the surface with the steel rod using a rolling action. Clean any concrete from
around the base and top of the cone, push down on the handles and step off the footpaces.
 Carefully lift the cone straight up making sure not to move the sample.
 Turn the cone upside down and place the rod across the up-turned cone.

Workability Tests of concrete:-This test is performed to check the consistency of freshly made
concrete. The slump test is done to make sure a concrete mix is workable. The measured slump
must be within a set range, or tolerance, from the target slump.
Workability of concrete is mainly affected by consistency i.e. wetter mixes will be more
workable than drier mixes, but concrete of the same consistency may vary in workability. It can
also be defined as the relative plasticity of freshly mixed concrete as indicative of its workability.

Take several measurements and report the average distance to the top of the sample. If the
sample fails by being outside the tolerance (i.e. the slump is too high or too low), another must
be taken. If this also fails the remainder of the batch should be rejected.

CONCLUSION
We can conclude that there is difference between the theoretical and practical work done. As the
scope of understanding will be much more when practical work is done. As we get more knowledge in
such a situation where we have great experience doing the practical work.
Knowing the loads we have designed the slabs depending upon the ratio of longer to shorter span of
panel. In this project we have designed slabs as two way slabs depending upon the end condition,
corresponding bending moment. The coefficients have been calculated as per I.S. code methods for
corresponding lx/ly ratio. The calculations have been done for loads on beams and columns and designed
frame analysis by moment distribution method. Here we have a very low bearing capacity, hard soil and
isolated footing done.
