Before starting the construction work of a
residential building, the proper consideration should be given on the following
factors to choose the exact site for the building.
Topography, Nature of sub-soil, Position of the
ground water tablem, Facilities, Neighbourhood, Undesirable things near the
site, Vegetation, Shape of the site, Availability of men and materials,
Proximity to sea-shore, river or lake or the place of natural beauty
Topography: Plain Grounds : If the site is plain, the process for
marking, excavation and construction becomes easier without any leveling. But
the problem may arise for drainage. Besides, dull pools will be developed after
a deep shower. In dry weather, outflow of septic tank develops pools and
various diseases will be spread out due to mosquitoes and other insects.
Slopping
Grounds : A bare at least of 1% (1 in 100)slope is essential for smooth
drainage. At least 2% slope should be maintained for the drainage of lawns.
Slope is easily visible, if it surpasses 5%.A ground that is properly leveled
contains 0% slope but it is not perfect for construction whereas a slope among
3% and 10% is mostly recognized for constructions. Smooth erosion is possible
along these slopes after a deep shower and creep (downward sliding of the subsoil)is
generally occurred.
Undulating
ground : After proper leveling, construction can be built up on undulating
ground.
Low lying area : A low lying area is not recommended. Low lying
area next to water body as a lake, reservoir, tank, river or canal may come
with a nice view and arrange a superior comfort in severely chill and scorching
climate.
Nature
of sub-soil : If a soil contains strong bearing strength, a permanent building
can be easily developed. The soil that remains underneath the ground is known
as sub-soil. The soils which have gravel and sand are called dry soils. These
soils cause greater temperature and less humidity.
The position of ground water table : Ground Water Table (GWT)
should be located at minimum depth of 3 m underneath ground level.
Percolation
: Soils percolating at 180 s/mm are correspondingly less porous and pooling of
waste water is generally found in them.
Facilities : Community services like street cleaning, fire
protection and utilities like gas supply, drainage line, transport system
should have been easily accessible without incurring any additional cost.
