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).


8/12

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.


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.


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.


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.


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.
