PHOTOS OF THE BUILDING FOR ASSESSMENT, SHOWING THE IMPACTS
No parking space is provided at the front of the
building which leads to random parking by the
users in the front.
Parking space is provided at the side of the
building which is not visible and so it is not
much used.
(Rule not followed - Surface parking for at least
two car spaces shall be provided near entrance
for the physically handicapped persons)
All ACs outdoor units are placed on the frontelevation wall of the building which creates an
unpleasant scene. No proper arrangement for
the drain pipes.
Front set back is not measurable since there is
no boundary wall for the building.
(Rule not followed - The concrete paving
around the building has to be sloped at about 1
in 20 towards the pebble bed, so that rain
water from the terrace and side open spaces
flow over this pavement)
Drainage pipes are not properly covered
with ducts which may lead to leakage and
damage elevation wall of the building.
The drain pipe of the ACs outdoor unit is
not connected well to the ground.
The width of the lift door is only 1meter which is small for
the wheel chair to go in comfortably.
(Rule not followed - Among the lifts provided within the
premises at least one lift shall have the facility to
accommodate the wheel chair size 80cm x 150cm).
7/24/2019 HSS Assignment

The staircase is direct and easily accessible by
the users.
Rule followed - The width of the staircase is
2meter, which is minimum width for the
institutional building.
The distance between the two internal
staircases is about 15 meters, which is more for
the user to walk that far.
The ratio of the built-up area to the open area
in the building is more, which is comfortable
and spacious.
The width to height ratio is more which causesmore direct sunlight into the opposite corridors
and the open space, since not much shade of
the building falls on it.
A total of 4 staircase and 2 lifts are provided
but no fire extinguishing system is installed.
There is no rain water conservation system and the
drain pipe from which water is coming from the terrace
directly flows on the floor, making the floor slippery
during rain.
(Rule not followed all the drain pipes are not
connected to the rain water conservation system)
Sufficient number of toilets for men and
women are provided in each floor.
But they are located on far end of the
building which is difficult for the user to
find out and walk so far.
7/24/2019 HSS Assignment
9/12
The distance from one side entry to the other
side entry is almost 80meters which is very
far for a person to walk towards the other
end in the building.
Other staircase is provided almost in the
middle of the building but the distance
between the two staircases is almost 15-20m
which is far for the users to walk.
This staircase comes in the open area of the
building and it is projecting out which is
clearly visible by the users.
Some open space between the staircase and
the paved area in the courtyard is provided
for landscape but it is not properly used.
The area that is supposed to be for growing
plants and landscaping is used as a dumping
zone where all the unused building materials
are dumped.
Provisions are made for the rain water and
surface water from the floors to get collected
into the drain which is running all around the
courtyard, through the drain pipe.
7/24/2019 HSS Assignment
10/12
Provisions were made for lifts in the early
stages of the building construction but later it
is not being used.
No provisions for lift were made after the
completion of the building and now the place
is used as a storage space for the unused
furniture.
The space is not closed with door which
causes unpleasant scene in the building.
The lift space which is now unused wascovered with marble flooring but the lift well
was not closed and no such provisions were
given so that people come closer to it.
The entire lift well was left open as such from
top to bottom which is dangerous for the
users, since people may fall into it
accidentally.
Electrical equipment was kept open in the
corner of the floor with all wiring being open.
This space was actually meant for the water
cooler but it is being misused and it has a sink
at the side of it, it was meant for refreshment
for the users.
There is only water cooler for the entire
building at the ground floor which is not
sufficient for the users of the building.
7/24/2019 HSS Assignment
11/12
A balcony space is provided in first and second floornear the labs for refreshment but that is used as a
storage space and all the unused furniture is
dum ed there.
Gas cylinders that are used in the lab areplaced outside on the floor and no fire
extinguisher is there in the building which is
ver dan erous for the users.
All the drain pipes from the toilets are left open without covering them with ducts which
causes an unpleasant scene, since it is on the side entry of the building which is often
used by the people after they park their vehicles in the parking zones at the side.
7/24/2019 HSS Assignment
12/12
Parking space for the cycles and the bikes is provided at the side of the building, which is not visible
for the users approaching the building from the front. This leads to more parking in the front of the
building than at the sides where parking space is provided.
Car parking space is insufficient for this building and so many users park their car on the road
abutting the side of the building or in front of the building causing disturbance for other people
The sewer pipe connecting to the tank at
the ground is not properly maintained and
not closed.
This causes an unpleasant scene and may
lead to health problems for the users and to
the surroundings.
