Green belt around the periphery

14 Disposal of

liquid waste

Underground sewerage line will be connected to the sewage

treatment plant from each facility.

Laundry wastewater will be collected and treated in separate

system.


6 | P a g e

15 Solid Waste

disposal

About 12-13 kg per day of municipal waste out of which 9 kg will

be biodegradable and the remaining non-biodegradable. These

wastes shall be disposed off suitably as per the guidelines.

After expansion additional about 400 kgs per day of Municipal

waste shall also be generated, this will be disposed off suitably

through KMC.

Solid wastes generating from the construction activities such as

bricks, stonechips, sand etc. will be used in the site & road

construction. The construction waste will not contain any asbestos

or hazardous materials.

Sludge (5 kgs/day) generated from sewage treatment plant will be

disposed locally as manure in the greenbelt.

16 Construction

waste disposal

(non hazardous)

To be disposed through Municipal Corporation to the nearest

dumping ground

17 Biomedical waste It has been estimated that about 1.84 tons per month of Bio

Medical Waste (BMW) is generated from the existing health care

facility which is being disposed off to Medicare Environmental

Management Pvt. Ltd. facility in line with the prescribed

guidelines.

There will be an increase of about 100 kgs per month of BMW

from the proposed additional development.

18 Hazardous

wastes (as per

Hazardous Waste

Management

Rules)

There will be no storage of hazardous waste within the complex

except small amount of spent oil from D.G. Sets, which will be

either disposed off to an authorized vendor.

1.3. What are the likely impacts of the proposed activity on the existing facilities

adjacent to the proposed site? (Such as open spaces, community facilities, details of the

existing land use, disturbance to the local ecology).

Since it is an expansion of hospital over the existing buildings there will be no effect on the

Open Spaces but total build up will be done based on the existing land use.

Proposed hospital project site is surrounded by some Residential and Commercial complexes,

shopping malls and Project site will be build up in conformity to the existing Building Law

and Rules of the Local authority.

Proposed hospital project will be self sufficient as per as facilities are concerned so there will

be hardly any impact on the existing facilities.


7 | P a g e

The operation of the hospital after expansion will provide value addition to the existing

infrastructure, as due to its development, facilities such as better inpatient treatment facilities,

water supply, telecommunications etc. shall be upgraded in and around the project premises.

The operation of project and other allied facilities will provide direct or indirect employment

opportunities for a large section of society. The employment will have positive impact

thereby increasing the quality of life.

Since there is no such Ecological Important Places nearby to the proposed expansion of

hospital so chances of disturbance to the local ecology is very negligible.

1.4. Will there be any significant land disturbance resulting in erosion, subsidence &

instability? (Details of soil type, slope analysis, vulnerability to subsidence, seismicity etc

may be given).

Necessary Soil Investigation has already been conducted by a structural consultant and copy

of the Report is enclosed herewith for kind Reference and the same is self explanatory.

No, land disturbance resulting in erosion, subsidence & instability is anticipated. Proper

greening & paving of the area will not cause any soil erosion problem and subsidence. The

proposed project area comes in Seismic zone-III which is low damage risk zone. Hence the

area is not sensitive to any possible earthquake.

Seismicity: Site is located at Zone III.

Seismic Zone Map of India is enclosed as per Attachment 2

The Detail Geo Technical Soil Report Is enclosed as Attachment 3

1.5. Will the proposal involve alteration of natural drainage systems? (Give details on a

contour map showing the natural drainage near the proposed project site)

The existing land of hospital is almost plain and green belt covers with local trees, shrubs so

the proposed expansion of hospital will not affect the natural drainage systems of the area.

The Proposed Project activities will not cause any alteration of natural drainage system. The

drainage network map has been provided as Attachment 4.

1.6. What are the quantities of earthwork involved in the construction activity-cutting,

filling, reclamation etc. (Give details of the quantities of earthwork involved, transport

of fill materials from outside the site etc.)

Since the new floors will be coming up over the existing buildings no excavation work is

necessary. The excavation work if required will be minimal.

During construction phase no excavation is envisaged in order to provide foundations. If any

excavation is required the excavated material will be properly stacked within the site under

tarpaulin cover; and will be reused for backfilling purpose, road construction etc. The top-soil


8 | P a g e

will be preserved separately and will be used for landscaping purpose only. Hence, no

immediate adverse impacts on the land environment are envisaged.

Hardly any filling materials will be transported from outside the Project site, because each

work and construction work will be scheduled and plan in such a way that excavated earth

work (if any) will be kept just adjacent to the building which needs excavation and it will be

filled up with the same earth materials.

Regarding reclamation work balance earth material and construction debris will be used for

the purpose.

1.7. Give details regarding water supply, waste handling etc during the construction

period.

Water supply: During construction phase water will be sourced from Kolkata Municipal

Corporation (KMC) water supply.

Waste management: Soil excavated will be reused for backfilling and the fertile topsoil will

not be affected. Excess soil if any, will be used for green belt development, road construction.

Spillage from the oil from machinery or cement residual from concrete mixer plants will be

properly collected and disposed off.

For construction labours proper sanitary facilities & wash area will be provided with good

hygienic condition.

Provision of drinking water, wastewater disposal and solid waste management should be

ensured for few labour camps during the construction period. Water for construction related

work will be taken from one of the existing bore wells. Proper sanitation facilities will be

provided to the construction workers to ensure water pollution control. Sewage generated

from the occupied area by labours will be directed to onsite Sewage treatment plant.

Construction period is estimated to be about 10 months.

Good construction practices

o Hazardous materials if any will not be stored near surface water and will be stored near

plastic sheeting to pits for prevention of leakages.

o Waste bricks and concrete is a good material for filling. Steels from RCC must be

carefully segregated and rest of the materials will be crushed on site. Crushed masonry &

concrete is even good for manufacture of synthetic aggregates. Delivery of materials on

site must be done over a durable impervious and level surface so that 1st batch of

materials does not mix with the site surface.

o Availability of covered storage should be assured. Mobile and covered storage boxes with

easy drawing and filling mechanism can be used.


9 | P a g e

o Recyclable materials like plastics, metal scraps will be sent to recycling units and other

scraps will be stored in suitable places. Construction process will be dry and will reduce

the amount of water consumption and the waste generation will also be minimal. Using of

interlocking bricks, pre-cast roofing and wall panels etc will be used. This will also

reduce the amount of waste generation.

o Durable materials do not require frequent maintenance will be used. Exposed brickwork

in hot & dry climate with class 1 bricks required minimum maintenance. Instead of using

stone masonry, stone cladding is better way to minimize maintenance.

1.8. Will the low lying areas & wetlands get altered? (Provide details of how low lying

and wetlands are getting modified from the proposed activity)

The Proposed expansion of hospital will be on existing buildings and no additional land is

required. The existing land is almost plain land and there are no low laying areas & wetlands.

So modification of any wetlands is not applicable for the proposed activity.

1.9. Whether construction debris & waste during construction cause health hazard?

(Give quantities of various types of wastes generated during construction including the

construction labour and the means of disposal)

Solid wastes of construction phase will constitute excess excavated earth and construction

debris with bits & pieces of steel, packaging materials, woods used for shuttering.

Construction debris will be disposed off in low-lying area/approved dumping yards as

instructed by the local Municipal authority. Cement bags, waste paper, air-conditioning

insulation material, and cardboard packing material will be sold off to recyclers. Unusable

steel bits and pieces will also be collected at site and sold to recyclers. During construction

period some portions of food wastes which area bio degradable will be generated and will be

stored in Bins as per the allocated area at the project site where from it will be taken by local

authority periodically.

Approximately 100-150 skilled, unskilled and professional work force including temporary

and permanent employees shall be required during the construction period. Proper sanitary

facilities will be provided to construction laborers and treatment will be done using septic

tank. Wash areas will be constructed and good hygienic condition will be maintained. Hence,

no adverse impacts on human health are envisaged.

Collection and storage of hazardous wastes during Pre construction and Post construction

o Lead based paints and other hazardous materials may be removed from the structure prior

to deconstruction or demolition activities to minimize special handling and disposal

requirements for the construction and demolition waste.


10 | P a g e

o These activities must be conducted by qualified personnel using appropriate health and

safety procedures in accordance with the regulatory requirements.

o Isolated storage for hazardous wastes released from the whole site should be provided on

site.

o Source segregation of similar wastes is highly recommended.

o Installation of fire extinguisher is mandatory near storage of hazardous wastes.

2.2. What is the capacity (dependable flow or yield) of the proposed source of water?

Water demand for the Hospital for the different components like Main building, Oncology

dept, Day care dept. blocks, canteen, laundry etc. has been calculated to be 800 m3/day

(Domestic – 600 m3/day, Cooling – 100 m3/day, Additional – 100 m3/day). During the

operational phase, water will be primarily sourced from KMC and supplied water will be used

after treatment through proper Water Treatment Plant.

2.3. What is the quality of water required, in case, the supply is not from a municipal

source? (Provide physical, chemical, biological characteristics with class of water

quality)

Since there is a remote chance of getting 100% Supply water form Government and Local

Authority in near future so Project Proponent has to depend on Bore well water. The project

proponent will try to minimize the supply water usage depending on the available supply

water form Kolkata Municipal Corporation.

The quality of required as per IS: 10500: 2012 will be as follows:

2.4. How much of the water requirement can be met from the recycling of treated

wastewater? (Give the details of quantities, sources and usage)

100% of the waste water will be treated at the Sewage treatment plant and 60% will be used

for internal purpose and 40% will be sent to municipal sewerage system.

Water source: Kolkata Municipal Corporation (KMC) supply.

During the operational stage of the proposed site, the wastewater will be treated up to a

tertiary level in a Sewage Treatment Plant (STP) of 500 KLD capacity. Entire Treated water

of will be reused and recycled in flushing, gardening, cooling tower, road washing.

2.5. Will there be diversion of water from other users? (Please assess the impacts of the

project on other existing uses and quantities of consumption)

No, there will not be any diversion of water from other users and water requirement for the

Proposed Project will be met form the proposed Bore well water and Kolkata Municipal

Corporation Supply.

As the water supply will be well planned for the project, so there will not be any likely

impacts on others due to water use by this particular project.

2.6. What is the incremental pollution load from wastewater generated from the

proposed activity? (Give details of the quantities and composition of wastewater

generated from the proposed activity)

Wastewater in the tune of 490 m3/day (80% of domestic water demand of 600 m3/day),

would be generated from the entire project that would be treated in the Sewage Treatment

Plant. Approximately 90% of the total waste water generated will be reclaimed after


13 | P a g e

treatment in sewage treatment plant to flushing, gardening, cooling tower, road washing.

Hence the incremental pollution load is virtually nil.

2.7. Give details of the water requirements met from water harvesting? Furnish details

of the facilities created.

The recent Guidelines issued by SEAC will be followed, and the necessary steps will be

taken will regard to Rain Water Harvesting at the time of execution of the project as per

guidelines and considering the site condition.

The modern methods of rainwater harvesting can be broadly categorized under two –

1. Collection and storage of rainwater for direct use, and


14 | P a g e

2. Groundwater recharging.

A combination of these two are also practiced, where rainwater is collected and stored in

containers for direct use while the collected rainwater in excess of the storage capacity is

charged into ground (groundwater recharging).

Rain Water Harvesting, is an age-old system of collection of rainwater for future use. But

systematic collection and recharging of ground water, is a recent development and is gaining

importance as one of the most feasible and easy to implement remedy to restore the

hydrological imbalance and prevent a crisis. Rain Water Harvesting is a way to capture the

rain water when it rains, store that water above ground or charge the underground and use it

later.

Rooftop rainwater harvesting: Rooftop rainwater from the main building, Oncology facility

area and day care facility area is flown down to the ground and then taken to storm water

drains. The storm water drains are intercepted at strategic locations and rainwater is diverted

into recharge wells. The recharge wells will be provided with recharge bores to facilitate the

recharge. Layers of filtering material like boulders, pebbles and coarse sand inside the

recharge well ensure efficient filtration. In addition to this Rain water harvesting and

groundwater recharge structures will also be constructed outside the plant premises in

consultation with to augment the ground water level.

In scientific terms, water harvesting refers to collection and storage of rainwater and also

other activities aimed at harvesting surface and groundwater, prevention of losses through

evaporation and seepage and all other hydrological studies and engineering inventions, aimed

at conservation and efficient utilization of the limited water endowment of physiographic unit

such as a watershed. Rain is a primary source of water for all of us. There are two main

techniques of rainwater harvesting:

• Storage of rainwater on surface for future use.

• Recharge to groundwater.

Directly collected rainwater can be stored for direct use or can be recharged into the

groundwater. All the secondary sources of water like rivers, lakes and groundwater are

entirely dependent on rain as a primary source.

Rainwater harvesting structures shall be provided to recharge the groundwater resources in

the region. The run-off water from the roof of the structures and paved areas shall be

collected through storm water drainage system and led to rain water harvesting structure.


15 | P a g e

Rainwater Harvesting Facilities

• Groundwater Recharge with Rain Water Harvesting

There is generation of surface run-off from the plant facility during monsoon season. The

run-off will be of two types, i.e., run-off from the pervious area of the facility site and run-off

from the built-up area of the facility.

• Run-off from the Built-up Areas

The run-off from the paved surfaces of the proposed facility will be routed through a

carefully designed storm water drainage network and collected in storm water collection

sump and excess rainwater will be discharged to bore wells constructed on these internal

drains.

• Run-off from the Pervious Area

The run-off from the pervious area will be routed directly to the rainwater harvesting

structures constructed at suitable locations as per the contours.

For augmenting the ground water resources in the plant premises, number of rainwater

harvesting pits will be constructed and the internal drains where excess rain water flowing in

drain will be diverted to these pits. These structures will facilitate percolation of water into

the ground and thus augmenting the groundwater sources. The roof top water will be routed

to the storm drains. This will result in increase in groundwater tables and to some extent the

improvement of ground water quality.

The size and the locations of rainwater harvesting pits will be decided during detailed

engineering of the project.

Run off from the proposed project site is calculated using rational formula:

Q = C x I X A

Q = Run-off in m3/hr

A = Catchment Area (Sq.m)

C = Coefficient of Run-off

I = intensity of Rainfall in mm/yr

Roof Top

Drainage area in sqm = 7602 Sq.m

Coefficient of run-off 0.85

Runoff = 128 cum/day

Therefore, Total rainwater to be harvested = 128 cum/day

2.8. What would be the impact of the land use changes occurring due to the proposed

project on the runoff characteristics (quantitative as well as qualitative) of the area in


16 | P a g e

the post construction phase on a long term basis? Would it aggravate the problems of

flooding or water logging in any way?

No adverse impacts are envisaged due to proposed project on the runoff characteristics of the

area as adequate arrangements have been made and suitable storm water drainage system has

been provided.

During the construction phase, Runoff from the project shall not be allowed to stand of enter

into the roadside or nearby drain. Adequate measures shall be taken to collect such runoff and

shall be reused. Suitable garlanding drain as per the existing contours of the plot will be

developed.

Beautiful Landscaping with Internal Road Networking, Car parking areas, and other hard and

soft areas will be built up in such a manner that surface runoff possibilities will be minimum

and it will not aggravate the problems of flooding or water logging in any way.

Kindly refer to the enclosed Master Land Scape Plan for details as per Attachment 1.

2.9. What are the impacts of the proposal on the ground water? (Will there be tapping

of ground water; give the details of ground water table, recharging capacity, and

approvals obtained from competent authority, if any)

Water requirements for the proposed project will be met from Kolkata Municipal Corporation

(KMC) supply. Necessary approval will be obtained from competent authority in due course

of time adequate arrangements will be made to trap the rainwater.

Ground Water Table in nearby Project: 7-10 ft [approximate]

2.10. What precautions/measures are taken to prevent the run-off from construction

activities polluting land & aquifers? (Give details of quantities and the measures taken

to avoid the adverse impacts)

The precautions/measures to be taken to prevent the runoff from construction activities are

mentioned in the Environmental Management plamn, enclosed. However, broadly it can be

mentioned that the no construction wastewater will be discharged directly in to the land or

storm water drain. A couple of Sediment traps of 2.5m(L) x2.5m(W) x 0.75m(D) and half an

hour retention period will be constructed during construction stage, where all construction

wastewater will be discharged. After sedimentation, comparatively cleaner water will be

partially reused and rest part will be diverted to the existing drain which is going out of the

premises and joining the natural drain.

During the construction operation, Runoff from the construction site shall not be allowed to

stand or enter into the roadside. Hence the aquifer level will not get affected.


17 | P a g e

On-site sanitation facilities will be provided and water will be reused and disposed off into

septic tanks followed by soak pits. Precaution will be taken for wastewater collection and

disposed so that overflow will be negligible.

Adequate measures shall be taken to collect such run off and either shall be reused (if

possible) or disposed at the designated construction waste disposal location.

2.11. How is the storm water from within the site managed?(State the provisions made to

avoid flooding of the area, details of the drainage facilities provided along with a site

layout indication contour levels)

During the post-construction stage the storm water will be collected in to the surface drainage

network inside the campus. The drain sizes and sections will be designed in such a way that

they can take the load of the peak rainfall period. All the surface drains will be covered by

gratings to avoid the litter and other inert waste. Proper land gradient will be provided so that

water logging inside the campus does not occur. The collected storm water from the building

roofs during the rainfall period will be directed into the rain water harvesting pits inside the

campus. The storm water of the ground surface will also be discharged into the said recharged

pits. Overflow from the said recharged pit will be directed to the existing drain. To reduce the

surface runoff and subsequent increase in infiltration of rainwater, attempts will be made to

maximize the green surface inside the campus.

As the site is located in a comparatively flat terrain, appreciable contour levels are not

available. Proper land grading will be provided so that the slope of the modified ground level

remains towards the existing drains. Drainage and sewerage map enclosed in the Attachment.

An elaborate storm water disposal scheme has been planned and shall be implemented to

manage the storm water run-off from within the site.

The total land is to be divided on number of catchment area based on land area configuration.

Composite runoff coefficient estimated on basis of paved, unpaved ratio as applicable in this

project. Efficient drainage system shall be provided in the site with network of underground

RCC pipes with Intermediate catch basins, gully chambers and storm water manholes.

Some of the strategies to mitigate impervious surfaces are:

o Smaller building footprint.

o Pervious paving

o Covered parking under hospital premises.

o Clustering the development together to reduce the paved surface required for roads and

sidewalks.

Implementation of a storm water management plan that prevents the post development peak

discharge quantity from exceeding the pre-development peak discharged quantity.


18 | P a g e

Implementation of a storm water management plan that protects the drains and receiving

channels. Storm water runoff outside the site could be significantly reduced by reuse storm

water volumes generated for non-potable applications such as landscape irrigation, toilet and

urinal flushing.

Reduction in the generation of storm water volumes would help maintain aquifer recharge

cycle and in addition storm water volumes would not have to be conveyed to receiving water

by the municipality, which reduces the load on municipality drainage system, and receiving

waters are not impacted.

Best Management Practices employed to capture and or treat storm water runoff.

2.12. Will the deployment of construction labourers particularly in the peak period lead

to unsanitary conditions around the project site (Justify with proper explanation)

The construction laborers will be hired from local area. Deployment of construction laborers

will not lead to unsanitary conditions around the project site as proper sanitary facilities like

common bath place, temporary toilets etc. will be provided to laborers and treatment will be

one using septic tank.

2.13. What on-site facilities are provided for the collection, treatment & safe disposal of

sewage? (Give details of the quantities of wastewater generation, treatment capacities

in detailed EMP.

2.14. Give details of dual plumbing system if treated waste used is used for flushing of

toilets or any other use.

Dual plumbing system will be implemented separately to domestic water supply and treated

water supply for flushing.

3. VEGETATION

3.1. Is there any threat of the project to the biodiversity? (Give a description of the local

ecosystem with it’s unique features, if any)

No. The project will not pose any threat to the bio-diversity of the locality. No tree exists

within the project site. Also, as the project site does not contain any water body, therefore, no

scope of disturbance to the terrestrial or aquatic flora is involved. Moreover, quite a number

of trees are also going to be planted during the later period of the construction stage. The

species will be predominantly native in nature so that they merge with the local ecosystem.


19 | P a g e

3.2. Will the construction involve extensive clearing or modification of vegetation?

(Provide a detailed account of the trees & vegetation affected by the project)

No. The construction activity will not involve any clearing of trees, as no tree exists within

the project site, already mentioned. The existing garden area will not be hampered rather it

will be increased as green belt. So any trees or vegetation will not be affected by the proposed

expansion of project.

3.3. What are the measures proposed to be taken to minimize the likely impacts on

important site features (Give details of proposal for tree plantation, landscaping,

creation of water bodies etc along with a layout plan to an appropriate scale)

The landscape of project site has been planned to provide a clean, healthy and beautiful green

environment for the patients. Within the proposed project site landscape / green areas will be

developed to achieve a blend between modern building and various species of plants to create

a clean, healthy and aesthetic environment that provides a visual retreat and relaxation to the

people who will come to work in these buildings.

A combination of evergreen and ornamental flowering trees, palms, shrubs and ground covers

will be planted along the sides of the roads and in open spaces a setback areas within the

Park.

It is recommended that tree plantation (large size species) should be undertaken at the time of

preparation of the site so that they would grow to considerable size by the time of

commissioning of the proposed project.

4. FAUNA

4.1. Is there likely to be any displacement of fauna- both terrestrial and aquatic or creation

of barriers for their movement? Provide the details.

The proposed expansion of the hospital will be over the existing building only; this place is

not that habitat for any kind of local fauna. There will be no displacement of Terrestrial &

Aquatic Fauna and the project does not create any barriers for their movements.

No such barriers will be created and no question of any displacement is applicable.

4.2. Any direct or indirect impacts on the avifauna of the area? Provide details.

Within the proposed project site, green areas will be developed to achieve a blend between

Hospital buildings and various species of plants to create a clean, healthy and aesthetic

environment. Common nature variety of trees and ornamental flowering species will be

planted in the green space. Landscaping can have direct positive impact on the local avifauna,

as this will provide shelter to local birds.

No direct or indirect impacts on the avifauna of the area are envisaged.


20 | P a g e

4.3. Prescribe measures such as corridors, fish ladders etc to mitigate adverse impacts on

fauna

Not applicable in the present case

5. AIR ENVIRONMENT

5.1. Will the project increase atmospheric concentration of gases & result in heat islands?

(Give details of background air quality levels with predicted values based on dispersion models taking into account the increased traffic generation as a

result of the proposed constructions)

During the operational stage of the project, there is no constant source of emission from the

building, as mostly non polluting activities will be carried out. The only source of air

pollution is vehicular movement in and around the project premises and emission from DG

sets. However, as there will be a expansion of three blocks, there might remain a possibility

of slight increase in heat island effect, which can be mitigated in the following means:

1. Judicial layout of building blocks within the colony The shape of the building block within the colony is designed in such a manner that there

remains sufficient amount of external as well as internal open space around the block so that

the air movement does not get interrupted.

2. Reducing the footprint of building blocks within the colony 21% of the land area will remain as open space (mostly green). Therefore, much lesser heat

gain will over the green surface.

3. Selection of Building material The building materials will be selected in such a way that the solar heat gain over the vertical

surface and roof minimized.

4. Trees and Vegetation There will be sufficient number of shading trees to be planted within the project site area to

reduce the ambient air temperature within the project site and surroundings.

5. Reduction in Hard Surface Hard surface in the form of metallic road will be kept minimum. The pavements will be of

porous and light colored material.

Ambient air quality in and around the project site has been monitored.

The traffic movement also will be controlled within the colony. As there will not be any

emission generating activity during the operational phase of the complex, there will not be

any continuous source of emission and thus the ambient air quality will not be affected. The

traffic volume and movement also will be controlled within the complex.


21 | P a g e

Details of air quality and noise environment given in attached EMP report.

5.2. What are the impacts on generation of dust, smoke, odorous fumes or other hazardous

gases? Give details in relation to all the meteorological parameters.

During the construction stage of the project, there will be generation of dust, which is

controlled by sprinkling of water, covering building materials by tarpaulin, covering the

structure with Hessian clothes etc.

Gases generating during the construction and operation stages of the project are below the

specific limit as per norms.

Air Pollution Dispersion Relationship with Meteorology

Any study of air pollution should include a study of the weather patterns (meteorology) of the

local area because the fate of air pollutants is influenced by the movements and

characteristics of the air mass into which they are emitted. If the air is calm and pollutants

cannot disperse then the concentration of these pollutants will build up. Conversely, if a

strong, turbulent wind is blowing any pollution generation will be rapidly dispersed into the

atmosphere and will result in lower concentrations near the pollution source.

The measurements of wind speed and direction, temperature, humidity, rainfall and solar

radiation are important parameters used in the study of air quality monitoring results and to

further understand the chemical reactions that occur in the atmosphere. Meteorological

monitoring is used to predict air pollution events such as depression high pollutant

concentration days and to simulate and predict air quality using computer models.

Wind Speed and Direction

Wind speed and direction measurements are important for air quality monitoring. If high

pollutant concentrations are measured at a monitoring station the wind date recorded at the

station can be used to determine the general direction and area of the emissions. When the

likely source or sources have been identified they can they be reduce the impacts on air

quality.

Details of air quality management are given in the EMP report.

5.3. Will the proposal create shortage of parking space for vehicles? Furnish details of the

present level of transport infrastructure and measures proposed for improvement

blocks, the internal roads having adequate width for regular movement of vehicles and

movement of fire fighting vehicle during emergencies inside the campus. All internal roads

having width 5 mtr, where as keeping in view to the safe evacuation and traffic circulation the

proponent proposed to develop three separate entries and exit gate having width of 6 mtr.

Detail traffic movement plan is given in the EMP report.

5.5. Will there be significant increase in traffic noise & vibrations? Give details of the

sources and the measures proposed for mitigation of the above.

9.4. What passive solar architectural features are being used in the building? Illustrate the

applications made in the proposed project.

The building blocks will have vertical and horizontal sun shading protection in the form of

fins and chajjas. The design, vertical or horizontal projection of those sun shading devices

will be dependent upon the exposure of a particular surface to the sun. Passive features

include special glass panels for absorption of solar radiation.

9.5. Does the layout of streets & buildings maximize the potential for solar energy devices?

Have you considered the use of street lighting, emergency lighting and solar hot water

systems for use in the building complex? Substantiate with details.

Yes, the layout in between lanes and common places of the hospital building has been

designed to maximize the potential for solar energy devices. All efforts would be given for

optimizing the solar energy for lighting purpose.

After testing the viability, solar energy system will try to be used for street lighting,

emergency lighting & solar heating if the same will be cost effective because of the climate

condition of the proposed expansion project area.

9.6. Is shading effectively used to reduce cooling/heating loads? What principles have been

used to maximize the shading of Walls on the East and the West and the Roof? How

much energy saving has been effected?

Passive solar architectural measures have been adopted to provide shading devices for

windows and roof which would effectively reduce heating up of building envelope. Louvers

and sunshades will be use around windows in order to protect from direct sunlight. Roofs

will be painted with reflective, aluminum based paints with solar reflectance ranging from

03-0.6. This will result in less absorption of sunlight causing 40% back reflection and less

heating of building structures during summer season. This will effective reduce the heat load

one building envelope.

9.7. Do the structures use energy-efficient space conditioning, lighting and mechanical

systems? Provide technical details. Provide details of the transformers and motor

efficiencies, lighting intensity and air-conditioning load assumptions? Are you using

CFC and HCFC free chillers? Provide specifications.

There would be every for using energy efficient space conditioning, lighting, and mechanical

systems. Suitable energy optimization will be adopted during the calculation of energy load

of the proposed project.

• The space heating load will be minimized using passive solar structures and suitable

building envelops material.

• Compact Fluorescence lamps (CFL) will be used in place of incandescent and halogen

lamps in all common areas and basement parking.


33 | P a g e

• However, in hospital buildings, provision of Central air –conditioners will be provided

which will be CFC and HCFC free.

• Roof-top thermal insulation

• Use of solar energy in external lighting

• Maximum utilization of natural light

9.8. What are the likely effects of the building activity in altering the micro-climates?

Provide a self assessment on the likely impacts of the proposed construction on creation

of heat island & inversion effects?

The proposed project is expansion of existing hospital buildings due to which there will be

insignificant emission of air pollutants by vehicular movements and occasional use of DG

sets, hence no heat island effect is envisaged. Increased traffic generation and occasional use

of DG sets used due to project is not going to course significant increase in atmospheric

concentration of gases and will not result in heat island formation and inversion effects as

evident from pollutant dispersion modeling studies carried out for this project as discussed

earlier.

9.10. What precautions & safety measures are proposed against fire hazards? Furnish

details of emergency plans.

The fire fighting will be designed as per the recommendations of the National Building Code

of India 2005: SP-7: 1983 Part IV (Amendment No.3). The building has been classified

under Group-C: Institutional Buildings (Height above 24m but not exceeding 30m) in the

National Building Code.

Considering that the purpose of the building is a hospital to accommodate patients and

infants, as well as the height of the structure, it will be necessary and is advisable to provide a

proper and adequate fire fighting system including sprinkler system, wet riser internal

hydrant system and yard hydrants. The proposed fire fighting shall be consisting

Underground storage tank with a provision of fire brigade inlet and suctions connections.

Fire fighting pumps including main fire pump, jockey pump and diesel engine stand by pump

shall be provided. Fire extinguishers shall be provided at appropriate places as per relevant IS

codes.

Fire protection is one of the most essential services to be provided. The Project proponent has

taken into consideration this aspect and allocated necessary measures accordingly. The

following have been considered for providing the fire protection system to the Hospital

Project. Fire protection measures are adopted as per the requirements laid down by National

Building Code of India.

Emphasis shall be given on procuring fire resisting building materials.

Every building material has a fire resistance ration, which indicates the extent to which

materials resist the effect of fire. The common fire resisting materials include – masonry

walls, reinforced concrete, or protected side structural members, pre cast and pre stressed

concrete floors, roofs, etc.

Emergency Plan:

• An emergency management wing is to be developed among the top officials with

respective duties assigned to them during emergencies.

• Automatic fire alarm must be installed and should be checked periodically for its proper

functioning.


35 | P a g e

• An emergency siren can be installed at a suitable place so that everybody can hear the

sound.

• Communication facilities must be adequate and available during such emergency.

• Supply of first aid breathing apparatus must be available at the time of emergency.

• Emergency Lighting

The emergency lights operated on battery power should be provided at appropriate locations

– such as corridors common area, staircase, exit and entrance doors, parking, etc. the

Transformers will be kept energized and should feed independently alternate rows of lights

so that so that in case of failure of one transformer, there will not be complete darkness.

• Fire Safety

The building materials shall be of appropriate fire resistance standard. Further, design shall

include provision for the following:

� The electrical systems shall be provided with automatic circuit breakers activated by

the raise of current as we as activated by over current.

� Separate and individual circuit lines for water pumps, Lifts, Lightings, Fire pumps are

provided so that one switch operation of possible.

� Wet riser cum down comer is proposed for entire Media Park Project. Entire project

is protected by providing Fire hose reel to be reached to all parts of the proposed

project.

9.11. If you are using glass as wall material provides details and specifications including

emissivity and thermal characteristics.

In Fenestrations –Single glass 6mm relective, Double glass 6mm reflective + 12mm air gap +

6 mm clear glass has been proposed with a U value of 2.81 W/sqm K and a solar factor of

0.46.

9.12. What is the rate of air infiltration into the building? Provide details of how you are

mitigating the effects of infiltration.

Reduced air infiltration combined with proper ventilation cannot only reduce energy bills but

it can also improve the quality of indoor air. Outdoor air that leaks indoor makes it difficult

to maintain comfort and energy efficiency. In addition, air leakage accounts for 25 – 40% of

the energy used of heating and cooling in a typical building. For this purpose, the building

has been designed in a compact manner, leaving ventilation shafts in between of facilitation

the escape of hot exhaust air.

9.13. To what extent the non-conventional energy technologies are utilised in the overall

energy consumption? Provide details of the renewable energy technologies used.

After testing the viability, solar energy will also be used to meet electricity requirements. The

renewable energy systems in the form of Solar water heaters shall be installed in the roof top

of the buildings.

10. Environment Management Plan

The Environment Management Plan would consist of all mitigation measures for each

item wise activity to be undertaken during the construction, operation and the entire life

cycle to minimize adverse environmental impacts as a result of the activities of the

project. It would also delineate the environmental monitoring plan for compliance of

various environmental regulations. It will state the steps to be taken in case of

emergency such as accidents at the site including fire.
