CONCLUSION
AIM OF THE PROJECT
The aim of the project is to plan and design the framed structure an
administrative building.
INTRODUCTION
2.INTRODUCTION
A court is any person or institution with authority to judge or
adjudicate, often as a government institution,
with the authority to adjudicate legal
disputes between parties and
carry out the administration of justice in civil, criminal,
and administrative matters in accordance with the rule of
law. In
both common law and civil law legal systems, courts are the
central
means for dispute resolution, and it is generally understood
that all
people have an ability to bring their claims before a court.
Similarly,
the rights of those accused of a crime include the right to
a defense before a court.
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.
MERCANTILE BUILDINGS:
These buildings are used as shops, stores, market, for display a 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.
5.SELECTION OF PLOT AND STUDY
• Ease of drainage.
• Transport facilities.
• 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.
ADMINSTRATIVE BUILDING
Buildings which are work base of number of people should be located so as
to limit exposure of hazards.
Administrative Buildings should be situated in a safe area on the public side
of the security point. The main office block should always be near the main
entrance and other administration buildings should be near this entrance if
possible. Other buildings, such as canteen, medical centers, etc. should be in
a safe area and the latter should have ready access for food supplies.
All buildings should be upwind of plants which may give rise to
objectionable features.
a) BUILT UP AREA
Land Area: The Proposed project is being developed on the total plot area of
664994.1 m2
Built up Area: The built up area of the proposed project is 118552.98 m2
including the FAR.
Water Consumption: During the construction phase, water requirement will
be met through the treated water from private water tanker. It is estimated
that water demand during the construction phase may vary from 30 KLD.
The project site was a vacant land at the starting of construction only had
scanty vegetation mainly herbs and shrubs and possesses no existing
structure. Hence, no clearance of vegetation, no felling of trees and structure
was required. The green area has been planned to develop 10 % of open area
to provide beautiful and natural environment. The green area will be
developed as shelter belt, along with avenue plantation on both sides of road
lawns area including herbs and shrubs. The indigenous/local plants will be
planted, which will increase the aesthetic value of the area. Hence, there will
be no disturbance to the local ecology of the area.

9.ARRANGEMENT OF ROOMS
• COURT ROOM
• STORE ROOM
• OFFICE ROOM
• BATH & W C
• VERANDAH
• STAIR CASE
COURT ROOM:
Should be designed in a well ventilated manner for proper light and fresh air
as it will be the room with more occupancy.
OFFICE ROOM:
North aspects this makes more suitable since there will be no sun from north
side for most part of the year.
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.
STAIR CASE:
This should be located easily accessible to all member people, when this is
intended for visitors it should be in the front, may be on one side of verandah
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.
• To prevent sun’s rays & rain from entering a room through external
doors & windows sunshades are required in all directions.
STORE ROOM
There are no such proper orientation requirements with store room but it
should be capable to resist fire, seepage, etc.
ORIENTATION
After having selected the site, the next step is proper orientation of
building. Orientation means proper placement of various 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:
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 plateau 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.

CONCLUSION
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.
