2.INTRODUCTION
The asi s eeds of hu a existe es are food, lothi g’s & shelter. Fro ti es i e orial
man has been making efforts in improving their standard of living. The point of his efforts has
been to provide an economic and efficient shelter. The possession of shelter besides being a
basic, used, gives a feeling of security, responsibility and shown the social status of man.
Every human being has an inherent liking for a peaceful environment needed for his
pleasant living, this object is achieved by having a place of living situated at the safe and
convenient location, such a place for comfortable and pleasant living requires considered and
kept in view.
• A Peaceful environment.
The engineer has to keep in mind the municipal conditions, building bye laws,
environment, financial capacity, water supply, sewage arrangement, provision of future, aeration,
ventilation etc., in suggestion a particular type of plan to any client.

3. DEMAND OF HOUSES
The house is the first unit of the society and it is the primary unit of human habitation. The
house is built to grant the protection against wind, weathers, and to give insurance against
physical insecurity of all kinds.
The special features of the demand for housing consists of in its unique nature and depend on the
following factors.
• Rate of interest on investment e. g., low rates of interest with facilities of long term
payment may facilities investment in housing.

4.CLASSIFICATION OF BUILDINGS BASED ON OCCUPANCY
10
RESIDENTIAL BUILDINGS:
These building include any building in which sleeping accommodation provide for normal
residential purposes, with or without cooking and dining facilities.It includes single or multi-
family dwellings, apartment houses, lodgings or rooming houses, restaurants, hostels,
dormitories and residential hostels.
EDUCATIONAL BUILDINGS:
These include any building used for school, college or day-care purposes involving assembly for
instruction, education or recreation and which is not covered by assembly buildings.
INSTITUTIONAL BUILDINGS:
These buildings are used for different purposes, such as medical or other treatment or care of
persons suffering from physical or mental illness, diseases or infirmity, care of infants,
convalescents or aged persons and for penal detention in which the liberty of the inmates is
restricted. Institutional buildings ordinarily provide sleeping accommodation for the occupants.
ASSEMBLY BUILDINGS:
These are the buildings where groups of people meet or gather for amusement, recreation,
social, religious, assembly halls, city halls, marriage halls, exhibition halls, museums, places of
work ship, etc.
BUSINESS BUILDINGS:
These buildings are used for transaction of business, for keeping of accounts and records and for
similar purposes, offices, banks, professional establishments, courts houses, libraries. The
principal function of these buildings is transaction of public business and keeping of books and
records.
11
MERCANTILE BUILDINGS:
These buildings are used as shops, stores, market, for display an sale of merchandise either
wholesale or retail, office, shops, storage service facilities incidental to the sale of merchandise
and located in the same building.
INDUSTRIAL BUILDINGS:
These are buildings where products or materials of all kinds and properties are fabrication,
assembled, manufactured or processed, as assembly plant, laboratories, dry cleaning plants,
power plants, pumping stations, smoke houses, laundries etc.
STORAGE BUILDINGS:
These buildings are used primarily for the storage or sheltering of goods, wares or merchandise
vehicles and animals, as warehouses, cold storage, garages, trucks.
HAZARDOUS BUILDINGS:
These buildings are used for the storage, handling, manufacture or processing of highly
combustible or explosive materials or products which are liable to burn with extreme rapidly
and/or which may produce poisonous elements for storage handling, acids or other liquids or
chemicals producing flames, fumes and ex plosive, poisonous, irritant or corrosive gases
processing of any material producing explosive mixtures of dust which result in the division of
matter into fine particles subjected to spontaneous ignition.
12
5.SELECTION OF PLOT AND STUDY
Selection of plot is very important for buildings a house. Site should be in good place
where there community but service is convenient but not so closed that becomes a source of
inconvenience or noisy. The conventional transportation is important not only because of present
need but for retention of property value in future closely related to are transportation, shopping,
facilities also necessary. One should observe the road condition whether there is indication of
future development or not in case of un developed area.
The factor to be considered while selecting the building site are as follows:-
• Availability of public utility services, especially water, electricity & sewage disposal.
• Ease of drainage.
• Transport facilities.
13
6.SURVEY OF THE SITE FOR PROPOSED BUILDING
Reconnaissance survey: the following has been observed during reconnaissance survey of
the site.
• The site is very clear planned without ably dry grass and other throne plats over the entire
area.
• Detailed survey: the detailed survey has been done to determine the boundaries of the
required areas of the site with the help of theodolite and compass.
14
7.RESIDENTIAL BUILDING
Requirement for residential accommodation are different for different classes of people &
depends on the income &status of the individual a highly rich family with require a
luxurious building, while a poor man we satisfied with a single room house for even poor
class family.
A standard residential building of bungalow type with has drawing room, dining room office
room, guest room, kitchen room, store, pantry, dressing room, bath room, front verandah,
stair etc., for other house the number of rooms may be reduced according to the requirements
of many available.

9.ARRANGEMENT OF ROOMS
LIVING ROOM
• KITCHEN
• STORE ROOM
• BED ROOM
• OFFICE ROOM
• BATH & W C
• DRESSING ROOM
• VERANDAH
• STAIR CASE
18
LIVING ROOMS:
This is the area is for general use. Hence the living & drawing room should be planned near the
entrance south east aspects. During colder day the sun is towards the south & will receive
sunshine which is a welcoming feature. During summer sunshine ti the northern side & entry of
sunrays from southern or south – east aspects do not arise.
KITCHEN:
Eastern aspects to admit morning sun to refresh & purity the air.
BED ROOM:
Bed may also be provided with attached toilets, there size depends upon the number of beds, they
should be located so as to give privacy & should accommodate beds, chair, cupboard, etc., and
they should have north or – west south – west aspect.
Bath and w.c are usually combined in one room & attached to the bed room and should be well
finished. This should be filled with bath tub, shower, wash-hand basin, w.c, shelves, towels,
racks brackets, etc., all of white glazed tiles. Floor should be mosaic or white glazed files.
Instead of providing all bed room with attached bath and W.C separated baths & latrines may
also be provided
VERANDAH:
There should verandah in the front as well as in the rear. The front verandah serves setting place
for male members & weighting place for visitors. The back verandah serve a ladies apartment for
there sitting, working controlling, kitchen works etc., verandah project the room against direct
sun, rain & weather effect. They used as sleeping place during the summer and rainy season &
are used to keep various things verandah also give appearance to the building. The area of a
building may vary from 10% to 20% of the building.
19
STAIR CASE:
This should be located in a easily accessible to all members of the family, when this is intended
for visitors it should be in the front, may be on one side of verandah. It meant for family use
only, the staircase should be placed the rear. The stairs case should be well ventilated & lighted
the middle to make it easy & comfortable to climb. Rises & threads should be uniform through to
keep rhythm while climbing or descending.
• Long wall of the building should face north south, short wall should face.
• East and west because if the long walls are provided in east facing, the wall.
• A verandah or balcony can be provided to wards east & west to keep the rooms cool.
• To prevent sun’s rays & rain from entering a room through external doors & windows
sunshades are required in all directions.
20
ORIENTATION
After having selected the site, the next step is proper orientation of building. Orientation means
proper placement of rooms in relation to sun, wind, rain, topography and out look and at the
same time providing a convenient access both to the street and back yard.
• Solar heat
• Wind direction
• Humidity
• Rain fall
SOLAR HEAT:
Solar heat means sun’s heat, the building should receive maximum solar radiation in winter and
minimum in summer. For evaluation of solar radiation, it is essential to know the duration of
sunshine and hourly solar intensity on exposed surfaces.
WIND DIRECTION:
The winds in winter are avoided and are in summer, they are accepted in the house to the
maximum extent.
HUMIDITY:
High humidity which is common phenomenon is in coastal areas, causes perspiration, which is
very uncomfortable condition from the human body and causes more disomfort.
RAIN FALL:
21
Direction and intensity of rainfall effects the drainage of the site and building and hence, it is
very important from orientation point of view.
INTENSITY OF WIND:
Intensity of wind in hilly regions is high and as such window openings of comparatively small
size are recommended in such regions.
SITE CONDITIONS:
Location of site in rural areas, suburban areas or urban areas also effects orientation, sometimes
to achieve maximum benefits, the building has to be oriented in a particular direction.
LIGHTING:
Good lighting is necessary for all buildings and three primary aims. The first is to promote the
work or other activities carried on within the building.
The second is to promote the safety of people using the buildings. The third is to create, in
conjunction to interest and of well beings.
VENTILATION:
Ventilation may be defined as the system of supplying or removing air by natural or mechanical
mean or from any enclosed space to create and maintain comfortable conditions. Operation of
building and location to windows helps in providing proper ventilation. A sensation of comfort,
reduction in humidity, removal of heat, supply of oxygen are the basic requirements in
ventilation apart from reduction of dust.

12.DESIGN OF COLUMNS
• Columns are compression members.
• Larger spacing columns cause stocking columns in lower stores of multi storied
buildings.
• Columns are transmitted loads which are coming from slabs to foundations. Larger spans
of beams shall also be avoided from the consideration of controlling the deflection &
cracking.

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.
