2.2.1.1 Storm water drains:

Conservation of water resource is most important aspect of the project during

construction and occupation phases. Storm water drainage planning, domestic water

planning and sewerage transfer and sewage treatment planning are critical aspects of

construction and occupation stages of project.

Storm water drains will be provided all over the site to meet the expected increase in

the runoff during rainy seasons due to the impervious nature of the paved areas. The

site is uneven and it is proposed to maintain the levels as much as possible, hence

storm water outlets from the site are anticipated. The expected runoff is calculated for

the design of the storm water runoff and presented in following table.

Calculation for Storm Water Drain

Quantity of storm water:

(a) With out project

Area of Catchment, ‘A’ : 2.6404 Ha

Run off Coefficient, ‘C’ : 0.6

Maximum intensity of rainfall, ‘I’ : 40 mm/hr

Therefore Q : 0.176 m3/sec

(b) With project :

Area for catchment for roof and road : 1.826 Ha

Area of Catchment, ‘A’ : 1.826 Ha



Therefore Q = : 0.183 m3/sec

Area for catchment for open areas : 0.815 Ha



Therefore Q = : 0.054 m3/sec

Total Discharge : 0.237 m3/sec

But, Discharge, Q = A/V

Where,

A= Area of the Drain,

V= Max. Permissible Velocity : 6.00 m/sec for concrete drain

Area of drain, ‘A’ = Q/V : 0.039 m2

Taking depth of drain as 0.6 m at the

starting point : 0.6

Width of drain = Area/depth = : 0.066 m 66 mm

Width of the drain is to taken 66 mm and depth varies according to the slope of

ground.

Rainwater Harvesting Structures

Storm water drains are provided with rainwater harvesting structures which will act as

flow dissipaters and also as infiltration trenches to ensure percolation of water and

enhance the ground water table. Though the entire runoff from the roof is collected in

storm water collection sump and the over flow shall join the storm water drains. For

roads it is proposed to provide rain water harvesting structures and will be located at

downspouts in the plot area. The typical cross section of rainwater harvesting structure

is presented in fig 2.4.

Fig 2.4 Rainwater Harvesting Structures



2.2.1.2 Water Availability:

Water is required for the construction as well as during occupation stage as the same is

an important resource. The water requirement during construction is in the order of

100 cum/day with a peak demand of 200 cum/day, and during occupation stage in the

order of 556.9 KLD. The water resource available with the Municipal authorities was

studied to identify the source and feasibility. The water resource both domestic water

and sewage is dealt by the Hyderabad Metropolitan water supply and Sewerage Board

(HMWSSB) in the GHMC area. The HMWSSB has been maintaining the water supply

resources for Hyderabad along with the treatment of wastewater. The resources

available with the HMWSSB are presented in table 2.5.

It may be noted that the following water supply projects i.e., Krishna Phase III (Part II)

with 45 MGD capacity and Godavari phase – I with 172 MGD capacity is anticipated to

be operational during 2015 and 2016 respectively. It may also be noted that the

dependability of Osman sagar and Himiyath sagar is reduced to approximately 60%. 45

MGD supply is available.

Domestic Water: It is proposed to draw domestic water from the Hyderabad

Metropolitan Water Supply and Sewerage Board (HMWSSB) to mitigate the drinking

water demand, which has been encouraging bulk consumers. The water shortage if any

during summer season will be drawn from ground water sources. During the

construction stage, water will be sourced primarily through tankers that would be

arranged by the contractor or bulk supplies from HMWS&SB. During the project

operational stage the water demand shall be sourced bulk supplies from HMWS&SB.

The water requirement of the project during occupation stage is in the order of 556.9

KLD. The water requirement for the project during the occupation stage is presented

in table 2.6. The water savings for the project is presented in table 2.7.

Sewage treatment plant based on Fluidized Aerobic Bio Reactor (FAB) technology

PROCESS DESCRIPTION:

The raw sewage will be collected in a collection sump and pumped to mechanical bar

screen chamber for removal of large floating matter followed by grit removal in Grit

Chamber. The raw sewage will then be collected in an equalization tank for

homogenization of hydraulic load. The tank contents will be kept in suspension by

means of course bubble serration through pipe grid. The equalization tank, with air

flow indicator for continuous monitoring of air supply to the tank in order to avoid

septic conditions, will be covered from top (RCC or FRP) to avoid nuisance. The

equalized effluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) in

series where BOD/COD reduction can be achieved by virtue of aerobic microbial

activities. The oxygen required will be supplied through coarse air bubble diffusers.

The bio-solids formed in the biological process will be separated in the downstream

Tube Settler. The clear supernatant will gravitate to the chlorine contact tank where

sodium hypochlorite will be dosed for disinfection of treated water prior to disposal.

The biological sludge generated in the FAB and settled in the tube settlers will be

collected in a sludge sump and then pumped to sludge drying bed for de watering. The

dried sludge will then be disposed off suitably as manure. The schematics of the

process are shown. The two main components of the treatment system viz. The FAB

reactor and tube settler are described in the following sections.

Fluidized Aerobic Bio Reactor (FAB)

Conventional effluent treatment plants are large sized, power intensive and require a

lot of monitoring. Scarcity of open space and rising land a power costs have forced the

industries to look our for space saving, compact and efficient treatment options. This

has led to the development attached growth processes where the bio mass is retained

within the aeration tank obviating the need for recycle. These plants are not only

compact but also user friendly. The endeavor to have a continuously operating, no-

clogging biofilm reactor with no need for back washing, low head-loss and high specific

biofilm surface area culminated in the most advanced technology of aerobic biological

fluidized bed treatment where the biofilm (biomass) grows on small carrier elements

that move along with the water in the reactor. The movement is normally caused by

aeration in the aerobic version of the reactor.

The reactor combines all the advantages and best features of Trickling filters, Rotating

biological contractors, activated sludge process and submerged fixed film reactors while

eliminating the drawbacks of these systems. The plants are more compact and more

energy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up with

small carrier elements. The elements are made up of special grade PVC or

polypropylene of controlled density (shown in plate). For media of specific gravity 0.92-

0.96 the overall density could be expected to increase up to 9.5% when full of biomass

such that they can fluidize using an aeration device. A biofilm develops on the

elements, which move along the effluent in the reactor. The movement within the

reactor is generated by providing aeration with the help of diffusers placed at the



bottom of the reactor. Then thin biofilm on the elements enables the bacteria to act

upon the biodegradable matter in the effluent and reduce the BOD/COD content in the

presence of oxygen available from the air that is used for fluidization.

2.2.2.1 Water Requirement

The water required for this project is in the order of 39350 m3 for the entire project

implementation period. The peak demand for water may be 150 cum/day, however

typical daily consumption will be in the order of 100 m3/day. The required water will

be drawn from ground water sources. The project authorities explored the possibility of

using treated wastewater to meet partial requirement of water and could not identify a

reliable source. The water supply and plumbing will be optimized and low water

consuming faucets and flush tanks will be used to conserve water.

2.2.2.2 Construction Debris

The construction debris consists of various types of materials. The construction debris

will be in both hazardous and non hazardous categories. The hazardous debris consists

of empty containers of adhesives, thinners, paints, petroleum products; these empty



containers will be sold to authorized recyclers. The non-hazardous wastes contain

recyclable debris like iron and other metal, glass, plastics, cartons of paper, wood etc.

These wastes will be sent for reuse/recycle. The waste percentage will be in the order

of 2%. Construction debris containing bricks, demolished RCC will be used for land

filling in the place of sub grade.

2.2.2.3 Paints

All the paints used in the premises will be ensured to have an albedo of at least 0.4 to

increase the reflectivity and reduce the heat dissipation and heat island effects.

2.2.2.4 Work Force:

The labor/work force requirement is approximately 1000 man-days of various skilled

and unskilled employees. Sufficient labor force and skilled employees are available as

Hyderabad is a favorite destination of skilled employees and migrating people from the

rural areas. The peak labor force requirement will be in the order of 300 people and

some of the labor force will be provided with temporary accommodation within the

site.

2.2.2.5 Material preparation and transport

All the construction materials will be drawn from outside. The material will be

transported by trucks within the site and 10 tippers will be used for the purpose.

2.2.2.6 Batching Plant

The required concrete will be prepared in a batching plant to be located temporarily in

the site so as to maintain the quality and reduce the lead distance. The capacity of the

batching plant will be 30 m3 to 50 m3/hr. The raw mix design (Cement: sand: coarse

aggregates: water: admixture) is stored in electronic panel board and the quantities are

weighed automatically as per the design mix. Aggregates in the sizes of 10 mm, 20 mm

is stacked in separate bins and these materials are loaded into the hopper by scrapper

and load cells. Cement is provided to the mix through silos (40 MT to 20 MT capacity)

with the help of screw conveyor. Measured quantity of water and admixture is fed into

hopper though load cells. In the hopper coarse aggregates, fine aggregates, cement,

water and admixture gets mixed in required quantities by rotary motion of the mixer

and after proper mixing it is unloaded into transit mixers at the rate of 0.5 m3/minute.

The water consumption for this process is approximately 160 lts/m3 of concrete. The

entire operation is closed and there is no scope of fugitive dust as the operation is wet

in nature.

8.0 ENVIRONMENT MANAGEMENT PLAN

It is proposes to construct a Residential and Commercial project development in the

name of M/s RDB Cybercity Developers Private Limited at Hydernagar, Balanagar

Mandal, Medchal District. The project is envisaged to provide high-density housing to

meet the growing demands for housing in the growing urban area of Hyderabad falling

under Hydernagar, Balanagar Mandal, Medchal District. The area around the village has

a number of educational institutions and residential development. The project is

envisaged as Residential and commercial Project with environment friendly features to

cater to the growing market demand for quality housing. The demand for quality

housing from this area will be partially met from this project, apart from the demand

due to industrial nature of the surrounding areas. The village has a number of layouts

and rapidly turning into a residential and commercial zone for various types of socio

economic sectors.

8.1 PROJECT DETAILS

The project is envisaged as a residential and commercial building with various types of

dwellings with other amenities. The dwelling profile was decided after deliberations

with various agencies and research into the market demands and housing finance

options and the projected growth of employment profile, and the worker classification

of the area. The project is envisaged to develop 2.640 hectares of Survey No.163,

Hydernagar, Balanagar Mandal, Medchal District into Residential and Commercial units.

The site is surrounded by open lands in all the directions except north direction. An

existing 100 feet road (NH – 9) in North direction. The site location is 2.0 Km away

from the Hafeezpet railway station of Multi Modal Commuter Transport Services

(MMTS).

It is proposed to provide 5 Blocks, Block (A to D) with 2C+G+14 floors, Amenities block

with 2C+G+6 and Commercial block with 2C+G+6 floors. The land & allocation will be

optimized to ensure compliance with the FAR regulations of GHMC. The water

requirement of the project during operation will be drawn from HMWSSB. Sewage

treatment plant will be provided to treat the wastewater. Water conservation

measures will be incorporated in the plumbing designs. Water recycling/reuse will be

adopted by way of using treated water for toilet flush systems, and green belt

development. The treated effluent will be let-out into the drains provided by

Kukatpally municipality. The required power will be drawn from the TRANSCO and the

energy requirement will be optimized by adopting energy efficient design for lighting;

by providing open space between each flat to allow sunlight. Solar Energy will be used

for fencing, and other areas wherever feasible economically. Construction materials

will be drawn from local sources. The designs of the houses will also incorporate Indian

Architectural principles of “Vastu”, as the market demands the same. Construction

material will be drawn from local sources. The parking provision follows the guidelines

prescribed by HMDA/GHMC and Building policy.

8.2 MAJOR FINDINGS OF THE EIA

An EIA was conducted and the major findings of the EIA study are presented below;



8.3 ENVIRONMENTAL IMPACTS

Impact on Physical Resources

Construction of proposed project requires huge quantities of natural resources like

sand, sub grade and aggregate, and materials produced from natural resources like

bricks, cement and steel. The material shall be drawn from local sources, and the lead

distances range from 5 – 150 km. The impacts on physical resources of sand will be

irreversible. While bricks will be brought from kilns which use Coal ash. The material

requirement of steel, cement etc. will be purchased from manufacturers with in state.

Hence, no major impacts on physical resources as regards the availability and

procurement of construction material are anticipated due to the project.

Impacts on Air Quality

Impacts on air quality during construction stage are likely to be due to operation of

construction yards, material transport on trucks and fugitive emissions from the

construction sites. The model results for occupation stage show slight increase in the air

quality and in worst concentrations are falling within the site, and the results are with in

the prescribed limits.

Impacts on Noise Quality

Impacts on noise quality during construction stage will be significant. Hence the

construction near the habitation is proposed only during daytime. The impacts during

occupation stage will be on the plots adjacent to the road. Construction workers will be

provided with protection equipment to guard against the noise impacts. Noise

mitigating measures will be suggested for construction equipment and DG sets.

Impact on Flora

The project site and its surroundings do not form a habitat to any endangered flora.

There are very few trees within the project site due to anthropogenic pressures. The

project will enhance the aesthetics of the site due to the provision of avenue plantation

and central greening. This would ensure minimum impact on flora.

Impact on Fauna

As there are no endangered species of wild life in and around the project site, it is likely

to have minimal impact. The avifauna will find abode on the trees proposed to be

planted. This would enhance the aesthetics of the area. Pet animal faeces may lead

to pollution of water shed if allowed to join storm water drains.

Impact on Land use

There is no land acquisition for this project. The land use of the site fallow land and

classified as residential and commercial by GHMC. However the topography of the land

being rocky plains involves cut and fill operations. Erosion and sedimentation are

impacts anticipated during construction. Mitigation measures shall be adopted to

avoid the same. The area development would increase the housing activity in the

surroundings, which is a positive impact, as barren lands will be used for productive

usage, and the negative impacts will be pressure on the infrastructure facilities.

Impact on Surface Water Resources



The degradation of water quality can occur during construction phase from increased

sediment load into watercourses near the construction site. Suitable mitigation

measures proposed, as part of the EMP will ensure that the residual impacts are

minimal. Storm water runoff would increase due to the increase in impervious surface,

and rainwater-harvesting structures will be provided as mitigation measure. The design

of the storm water drain will consider the additional runoff. The urban storm water

joining the storm water drain may carry pollutants from imperious surface.

Impact on Ground Water Resources

Ground water shall be drawn during construction, and will be used to augment the

municipal supply during non-monsoon season if necessary. Exploitation of ground

water will have an impact and the same shall be restricted to ensure resource

conservation. This impact will be marginal, as the ground water will not be drawn

continuously.

Impact on Human Use Values

The dominant land use in the area is residential, and expected commercial space will

increase the pressure on the residential localities. There is no additional requirement

and or acquisition of land. The project authorities will provide road safety measures to

reduce risk of accidents in the internal roads. The impact on Human use values is

marginal.

8.4 ENVIRONMENTAL MANAGEMENT MEASURES PROPOSED

A description of the various management measures during the various stages of the

project is provided in the following sections.

8.4.1 Pre-construction stage

During the design and preconstruction stage the management proposes to comply with

the regulations of town planning, explore the availability of sufficient resources, provide

plantation and sink bore wells after obtaining the necessary permissions, obtain all

necessary permissions from various statutory authorities after obtaining the relevant

permissions.

8.4.2 Construction stage

This will be the most crucial and active stage for the Environment Management Plan. In

addition to the monitoring of the construction activity itself to the pollution levels

within permissible limits, mitigation and enhancement measures for water resources

will go on simultaneously as the construction progresses. To facilitate implementation

of the enhancement and mitigation measures suggested, working drawings of the same

would be prepared after completion of detailed project report. In addition, the need

for a balanced evaluation and planning for risks associated with construction activities

related to housing project will be part of the supervising Contractors responsibility. The

resource conservation by way of identification of materials and construction debris

recycle/disposal will be formulated by the supervising consultants. The responsibility of

environment management plan lies with the project authorities who would implement

the plan in consultation with other consultants, by including appropriate provisions in

the contract/sub contract documents and providing the necessary facilities.



8.4.3 Operation stage

The environment management plan will be implemented by owners

associations/societies, where project authorities are co opted as members, and while

the management plan related to the utilities like roads, street lighting and common

open spaces lies with the Municipality. The management in operation stage will

essentially entail maintenance of sewage treatment plant, maintenance of utilities, and

monitoring activity in the project site. Monitoring for pollutants specified in the

Monitoring Plan will serve the two purposes. In addition to checking the efficiency of

the protection/mitigation/enhancement measures implemented, this will help verify or

refute the predictions made as a part of the impact assessment. Thus, it will complete a

very important feedback loop for the housing project.

The measures adopted and/or to be adopted during different stages of the project have

been detailed in table 8.1.

8.5 IMPLEMENTATION ARRANGEMENTS

The responsibility of implementing the mitigation measures lies with M/s RDB Cybercity

Developers Private Limited during design and construction stages while the

responsibility lies with the cooperative owner’s society and the Kukatpally Municipality

during occupation stage. All construction activities taken up by the project authorities

will be supervised by the Supervision Consultant (SC). Implementation schedule will be

worked for phase wise implementation of the mitigation measures after completion of

detailed designs. In the pre-construction phase of the project the supervision

consultants shall review the EMP to identify environmental and social issues and arrive



at a suitable strategy for implementation. The activities to be carried out and the target

dates will be worked out after completion of detailed designs.

8.6 INSTITUTIONAL STRENGTHENING

The management of M/s RDB Cybercity Developers Private Limited will evaluate the

organizational structure with respect to inadequacies in implementing the environment

management plans. The housing project is typical as the responsibility of management

lies with the owners/residents during occupation stage. The owners form a cooperative

society/association to manage the utilities and common areas in a normal case. M/s

RDB Cybercity Developers Private Limited will have little role to play in environment

management. Hence it is suggested to explore the possibility of co-opting a member

from M/s RDB Cybercity Developers Private Limited into these societies so as the spirit

of environment management plan is not lost. The common areas, electrical supply,

street lighting, open space of central green will be taken over and managed by the

Municipality and TRANSCO. The role of residents is limited to being stakeholders with

little say in the day-to-day matters; the town planning agencies and the government

must address this issue.

The Environment Management Plan envisages on-site monitoring of construction

activities for environmental pollution and will involve collection of samples and their

subsequent analysis. For this purpose two chemists would be required especially when

the implementation of the two phases goes on simultaneously. Induction of two more

assistant engineers, one each for the biophysical and social environment will also be

necessary.

8.7 TRAINING

The existing supervising staff and the additional staff have to be trained to effectively

carry out.

Co-ordinate, with supervision consultants and contractors on compliance

monitoring of mitigation measures during construction phase.

Monitoring of environmental components in the operation stage;

Co-ordinate with concerned departments on environmental issues;

Environmental impact studies for future housing projects;

Liase with State and Government of India on fiscal policies to reduce

environmental pollution from housing activity.

8.8 ENVIRONMENTAL MONITORING

8.8.1 Introduction

The environmental monitoring programme provides such information on which

management decision may be taken during construction and occupation phases. It

provides basis for evaluating the efficiency of mitigation and enhancement measures

and suggest further actions that need to be taken to achieve the desired effect.

The monitoring includes:

(i) Visual observations;

(ii) Selection of environmental parameters at specific locations;

(iii) Sampling and regular testing of these parameters.



8.8.2 Objectives

The objectives of the environmental monitoring programme are:

Evaluation of the efficiency of mitigation and enhancement measures;

Updating of the actions and impacts of baseline data;

Adoption of additional mitigation measures if the present measures are

insufficient;

Generating the data, which may be incorporated in environmental

management plan in future projects.

8.8.3 Methodology

Monitoring methodology covers the following key aspects:

Components to be monitored;

Parameters for monitoring of the above components;

Monitoring frequency;

Monitoring standards;

Responsibilities for monitoring;

Direct responsibility,

Overall responsibility;

Monitoring costs.

Environmental monitoring of the parameters involved and the threshold limits specified

are discussed below.

8.8.4 Ambient Air Quality (AAQ) Monitoring

Ambient air quality parameters recommended for road transportation developments

are Respirable Particulate Matter (RPM), Suspended Particulate Matter (SPM), Oxides

of Nitrogen (NOX), Sulphur Dioxide (SO2) and Lead (Pb). These are to be monitored at

designated locations starting from the commencement of construction activity. Data

should be generated over three days at all identified locations in accordance to the

National Ambient Air Quality Standards (Table 8.2) location, duration and the pollution

parameters to be monitored and the responsible institutional arrangements are

detailed out in the Environmental Monitoring Plan.

8.8.6 Noise Level Monitoring

The measurements for monitoring noise levels would be carried out at all designated

locations in accordance to the Ambient Noise Standards formulated by Central Pollution

Control Board (CPCB) in 1989 (refer) Sound pressure levels would be monitored on

twenty-four hour basis. Noise should be recorded at a “A” weighted frequency using a

“slow time response mode” of the measuring instrument. The location, duration and



the noise pollution parameters to be monitored and the responsible institutional

arrangements are detailed in the Environmental Monitoring Plan (Table 8.5)

Table 8.4 Noise level standards (CPCB)

8.9 REPORTING SYSTEM

Reporting system provides the necessary feedback for project management to ensure

quality of the works and that the program is on schedule. The rationale for a reporting

system is based on accountability to ensure that the measures proposed as part of the

Environment Management Plan get implemented in the project.

The reporting system will operate linearly with the contractor who is at the lowest rung

of the implementation system reporting to the Supervision Consultant, who in turn shall

report to the M/s RDB Cybercity Developers Private Limited. All reporting by the

contractor and Supervision Consultant shall be on a quarterly basis. M/s RDB Cybercity

Developers Private Limited shall be responsible for preparing targets for each of the

identified EMAP activities. All subsequent reporting by the contractor shall be

monitored as per these targets set by the M/s RDB Cybercity Developers Private Limited

before the contractors move on to the site. The reporting by the Contractor will be a

monthly report like report of progress on construction and will form the basis for

monitoring by the M/s RDB Cybercity Developers Private Limited, either by its own

Environmental Cell or the Environmental Specialist hired by the Supervision Consultant.

Monitoring of facilities at construction camps

Monitoring of air, noise, soil and water parameters including silt load

Monitoring of survival rate of plantation.

Monitoring of cleaning of drains and water bodies.



8.10 ENVIRONMENTAL MANAGEMENT BUDGET

The environmental budget for the various environment management measures

proposed in the EMP is detailed in Tabel 8.6 There are several other environmental

issues that have been addressed as part of good engineering practices, the costs for

which has been accounted for in the Engineering Costs. Moreover, since environmental

enhancements have not been finalized at this stage, the table projects the typical costs

aspect wise and the detailed cost estimate is presented in Annexure A

8.11 Horticultural and Landscaping Works

(a) Scope

The Horticultural and Landscaping works may be entrusted to a contractor. It would

generate local employment if the plantation, upkeep and maintenance of the green belt

were entrusted to local VSS bodies. Detailed drawings and designs of landscaping will

be drawn after completion of the detailed designing. The following precautions must

be taken while undertaking horticulture and landscaping works. The M/s RDB Cybercity

Developers Private Limited, project will have greenery by way of avenue plantation and

central green. The scheme of plantation and the figures are presented in mitigation

chapter. The upkeep and the management of the greening are presented as follows:



b) Materials

Plant Materials

Plant Materials shall be well formed and shaped true to type, and free from disease,

insects and defects such as knots, sun-scaled, windburn, injuries, abrasion or

disfigurement.

All plant materials shall be healthy, sound, vigorous, free from plant diseases, insects

pests, of their eggs, and shall have healthy, well-developed root systems. All plants shall

be hardy under climatic conditions similar to those in the locally of the project. Plants

supplied shall to confirm to the names listed on both the plan and the plant list. No

plant material will be accepted if branches are damaged or broken. All material must be

protected from the sun and weather until planted.

Any nursery stock shall have been inspected and approved by the Environmental

Specialist or the Engineer. All plants shall conform to the requirements specified in the

plant list. Except that plants larger then specified may be used if approved, but use of

such plants shall not increase the contract price. If the use of the larger plant is

approved, the spread of roots or ball of earth shall be increased in proportion to the

size of plant. Deliver plants with legible identification labels.

Top Soil (Good Earth)

Topsoil or good earth shall be a friable loam, typical of cultivated topsoils of the locality

containing at least 2% of decayed organic matter (humus). It shall be taken from a well-

drained arable site. It shall be free of subsoil, stones, earth skids, sticks, roots or any

other objectionable extraneous matter or debris. It shall contain no toxic material. No

topsoil shall be delivered in a muddy condition. It shall have pH value ranging between

6 and 8.5.

Fertiliser

Measurement of sludge shall be in stacks, with 8% reduction for payment. It shall be

free from extraneous matter, harmful bacteria insects or chemicals. (Subjected to

safety norms).

Root System

The root system shall be conducive to successful transplantation. While necessary, the

root-ball shall be preserved by support with Hessian or other suitable material. On soils

where retention of a good ball is not possible, the roots should be suitably protected in

such a way that the roots are not damaged.

Condition

Trees and shrubs shall be substantially free from pests and diseases, and shall be

materially undamaged. Torn or lacerated roots shall be pruned before dispatch. No

roots shall be subjected to adverse conditions such as prolonged exposure to drying

winds or subjection to water logging between lifting and delivery.

(c) Supply and Substitution

Upon submission of evidence that certain materials including plant materials are not

available at time of contract, the contractor shall be permitted to substitute with an



equitable adjustment of price. All substitutions shall be of the nearest equivalent

species and variety to the original specified and shall be subjected to the approval of

the Landscape Architect.

(d) Packaging

Packaging shall be adequate for the protection of the plants and such as to avoid

heating or drying out.

(e) Marking

Each specimen of tree and shrub, or each bundle, shall be legibly labelled with the

following particulars:

Its name.

The name of the supplier, unless otherwise agreed.

The date of dispatch from the nursery.

(f) Tree Planting

Plants and Shrubs

Trees should be supplied with adequate protection as approved. After delivery, if

planting is not to be carried out immediately, balled plants should be placed back to

back and the ball covered with sand to prevent drying out. Bare rooted plants can be

heeled in by placing the roots in prepared trench and covering them with earth, which

should be watered into, avoid air pockets round the roots. Trees and shrubs shall be

planted as shown in architectural drawings and with approval of site supervision

engineer.

Digging of Pits

Tree pits shall be dug a minimum of three weeks prior to backfilling. The pits shall be

120 cm in diameter and 120 cm deep. While digging the pits, the topsoil up to a depth

of 30 cm may be kept aside, if found good (depending upon site conditions), and mixed

with the rest of the soil.

If the side of the below, it shall be replaced with the soil mixture as specified further

herein. If the soil is normal it shall be mixed with manure; river sand shall be added to

the soil if it is heavy. The bottom of the pit shall be forked to break up the subsoil.

Back Filling

The soil back filled watered through and gently pressed down, a day previous to

planting, to make sure that it may not further settle down after planting. The soil shall

be pressed down firmly by treading it down, leaving a shallow depression all round for

watering.

Planting

No tree pits shall be dug until final tree position has been pegged out for approval. Care

shall be taken that the plant sapling when planted is not be buried deeper than in the

nursery, or in the pot. Planting should not be carried out in waterlogged soil. Plant

trees at the original soil depth; soil marks on the stem is an indication of this and should

be maintained on the finished level, allowing for setting of the soil after planting. All



plastic and other imperishable containers should be removed before planting. Any

broken or damage roots should be cut back to sound growth.

The bottom of the planting pit should be covered with 50mm to 75mm of soil. Bare

roots should be spread evenly in the planting pit; and small mound in the centre of the

pits on which the roots are placed will aid on even spread. Soil should be placed around

the roots, gently shaking the tree to allow the soil particles to shift into the root system

to ensure close contact with all roots and prevent air pockets. Back fill soil should be

firmed as filling proceeds, layer by layer, care being taken to avoid damaging the roots,

as follows:

The balance earth shall be filled in a mixture of 1:3 (1 part sludge to 3 part earth by

volume) with 50 gm potash, (Mop) 50gms of Super Phosphate and 1Kg. Neem oil cake.

Aldrin or equivalent shall be applied every 15 days in a mixture of 5ml in 5 litres of

water.

Staking

Newly planted trees must be held firmly although not rigidly by staking to prevent a

pocket forming around the stem and newly formed fibrous roots being broken by

mechanical pulling as the tree rocks.

Methods:

The main methods of staking shall be:

(a) A single vertical shake, 900mm longer than the clear stem of the tree, driven

600mm to 900mm into the soil.

(b) Two stakes as above driven firmly on either side of the tree with a cross bar to

which the stem is attached. Suitable for bare- rooted or Ball material.

(c) A single stake driven in at an angle at 45 degrees and leaning towards the

prevailing wind, the stem just below the lowest branch being attached to the

stake. Suitable for small bare- rooted or Ball material

(d) For plant material 3m to 4.5m high with a single stem a three- wire adjustable guy

system may be used in exposed situations.

The end of stake should be pointed and the lower 1m to 1.2m should be coated with a

non-injurious wood preservative allowing at least 150mm above ground level.

Tying

Each tree should be firmly secured to the stake so as to prevent excessive movement.

Abrasion must be avoided by using a buffer, rubber or Hessian, between the tree and

stake. The tree should be secured at a point just below its lowest branch, and also just

above ground level; normally two ties should be used for tree. These should be

adjusted or replaced to allow for growth.

Watering

The Landscape Contractor should allow for the adequate watering in of all newly

planted trees and shrubs immediately after planting and he shall during the following

growing season, keep the plant material well watered.



Fertilising

Fertilising shall be carried out by application in rotation of the following fertilisers, every

15 days from the beginning of the monsoon till the end of winter:

(1) Sludge or organic well-rotted dry farm yard manure: 0.05 cum or tussle.

(2) Urea 25 gm.

(3) Ammonium sulphate 25 gm.

(4) Potassium sulphate 25 gm.

All shrubs, which are supplied pot grown, shall be well soaked prior to planting.

Watering in and subsequent frequent watering of summer planted container- grown

plants is essential.

(g) Shrub Planting In Planter Beds

All areas to be planted with shrubs shall be excavated, trenched to a depth of 750 mm,

refilling the excavated earth after breaking clods and mixing with sludge in ratio 8:1 (8

parts of stacked volume of earth after reduction by 20%: 1 part of stacked volume of

sludge after reduction by 8%.)

Tall shrubs may need staking, which shall be provided if approved by the contracting

consulting engineer, depending upon the conditions of individual plant specimen. For

planting shrubs and ground cover shrubs in planters, good earth shall be mixed with

sludge in the proportion as above and filled in planters.

Positions of planters shall be planted should be marked out in accordance with the

architectural drawing. When shrubs are set out, precautions should be taken to prevent

roots drying. Planting holes 40 cm in diameter, and 40 cm deep should be excavated for

longer shrubs. Polythene and other non-perishable containers should be removed and

any badly damaged roots carefully pruned. The shrubs should then be set in holes so

that the soil level, after settlement, will be original soil mark on the stem of the shrub.

The holes should be back filled to half of its depth and firmed by treading. The

remainder of the soil can then be returned and again firmed by treading.

(h) Grassing

Preparation

During period prior to planting the ground shall be maintained free from weeds.

Grading and final weeding of the area shall be completed at least three weeks prior to

the actual sowing. Regular watering shall be continued until sowing by dividing the area

into portions of approximately 5m squares by constructing small bunds to retain water.

These 'bunds' shall be levelled just prior to sowing of grass plants; it shall be ensured

that the soil has completely settled.

Soil

The soil itself shall be ensured to the satisfaction of Landscape Architect to be a good

fibrous loam, rich in humus.

Sowing the grass roots

Grass roots (cynodon, dectylon or a local genus approved by the Landscape Architect)

shall be obtained from a grass patch, seen and approved before hand.



The grass roots stock received at site shall be manually cleared of all weeds and water

sprayed over the same after keeping the stock in place protected from sun and dry

winds.

Grass stock received at site may be stored for a maximum of three days. In case

grassing for some areas is scheduled for a later date fresh stock of grass roots shall be

ordered and obtained.

Execution

Small roots shall be dibbled about 5 cm apart into the prepared grounds. Grass will

only be accepted as reaching practical completion when germination has proved

satisfactory and all weeds have been removed.

Maintenance

As soon as the grass is approximately a 3cm high it shall be rolled with a light wooden

roller – in fine, dry weather – and when it has grown to 5 to 8 cm, above to ground

weeds must be removed and regular cutting with the scythe and rolling must be begun.

A top-dressing of an ounce of guano to the square yard or well decomposed well

broken sludge manure shall be applied when the grass is sufficiently secure in the

ground to bear the mowing machine, the blades must be raised an inch above the

normal level for the first two or three cuttings. That is to say, the grass should be cut so

that it is from 4 to 5 cm in length, instead of the 3 cm necessary for mature grass.

Damage failure or dying back of grass due to neglect of watering especially for seeding

out of normal season shall be the responsibility of the contractor. Any shrinkage below

the specified levels during the contract or defect liability period shall be rectified at the

contractor's expense. The Contractor is to exercise care in the use of rotary cultivator

and mowing machines to reduce to a minimum the hazards of flying stones and

brickbats. All rotary mowing machines are to be fitted with safety guards.

Rolling

A light roller shall be used periodically, taking care that the area is not too wet and

sodden.

Edging

These shall be kept neat and must be cut regularly with the edging shears.

Fertilising

The area shall be fed once in a month with liquid manure prepared by dissolving 45gms

of ammonium sulphate in 5 litres of water.

Watering

Water shall be applied at least once in three days during dry weather. Watering

whenever done should be thorough and should wet the soil at least up to a depth of

20 cm.



Weeding

Prior to regular mowing the contractor shall carefully remove rank and unsightly weeds.

Cultivating

The Landscape Contractor shall maintain all planted areas within Landscape contract

boundaries for one year until the area is handed over in whole or in phases.

Maintenance shall include replacement of dead plants, watering, weeding, cultivating,

control of insects, fungus and other diseases by means of spraying with an approved

insecticide or fungicide, pruning, and other horticulture operations necessary for proper

growth of the plants and for keeping the landscape sub-contract area neat in

appearance.

Pruning and Repairs

Upon completion of planting work of the landscape sub-contract all trees should be

pruned and all injuries repaired where necessary. The amount of pruning shall be

limited to the necessary to remove dead or injured twigs and branches and to

compensate for the loss of roots and the result of the transplanting operations. Pruning

shall be done in such a manner as not to change the natural habit or special shape of

trees.

Tree Guards

Where the tree guards are necessary, care should be taken to ensure that they do not

impede natural movement or restrict growth. Circular iron tree guards shall be provided

for the trees at enhancement locations. The specifications for which one given below:

Circular Iron Tree Guard with Bars.

The tree guard shall be 50 cm. in diameter.

The tree guards shall be formed of (i) 5 Nos. 25x25x3mm angle iron verticals 2.00m long

excluding splayed outward at lower end up to an extent of 10 cms. (ii) 3 Nos. 25x25mm

MS flat rings fixed as per design (iii) 15 Nos. 1.55 metres long 6mm dia bars. Each ring

shall be in two parts in the ratio of 1:2 and their ends shall be turned in radially for a

length of 4 cm at which they are bolted together with 8mm dia and 30mm long MS

bolts and nuts.

The vertical angle irons shall be welded to rings along the circumference with electric

plant 15 Nos. bars shall be welded to rings at equal spacing along the circumference of

ring. The lower end of the angle iron verticals shall be splayed outwards up to an extent

of 10cm. The lower end of the flat of lower ring shall be at a height of 45cm. and upper

end of the flat of top ring shall be at the height of 2.00 metres. The middle ring shall be

in the centre of top and lower ring. The bars shall be welded to rings as shown in the

drawing. The entire tree guard shall be given two coats of paint of approved brand and

of required shade over a priming coat of ready mixed primer of approved brand.

(i) Nursery Stack

Planting should be carried out as soon as possible after reaching the site. Where

planting must be a necessity and/or be delayed, care should be taken to protect the

plants from pilfering or damage from people animals. Plants with bare-roots should be



heeled- in as soon as received or otherwise protected from drying out, and others set

closely together and protected from the wind. If planting is to be delayed for more than

a week, packaged plants should be unpacked, the bundles opened up and each group of

plants heeled in separately and clearly labelled. If for any reason the surface of the

roots becomes dry the roots should be thoroughly soaked before planting.

(j) Protective Fencing

According to local environment, shrubs shall be protected adequately from vandalism

until established.

(k) Completion

On completion, the ground shall be formed over and left tidy.

8.12 Water Conservation Measures

Water conservation measures must be adopted during the occupation stage that would

conserve the natural resource and also reduce the pressure on other users. Typical lists

of water conservation measures are presented as follows;

Household Water Saving Measures

1. There are a number of ways to save water and they all start with you.

2. When washing dishes by hand, don't let the water run while rinsing. Fill one sink with

wash water and the other with rinse water.

3. Check your sprinkler system frequently and adjust sprinklers so only your lawn is

watered and not the house, sidewalk, or street.

4. Run your washing machine and dishwasher only when they are full and you could

save 3785 liters a month.

5. Avoid planting turf in areas that are hard to water such as steep inclines and isolated

strips along sidewalks and driveways.

6. Install covers on pools and check for leaks around your pumps.

7. Use the garbage disposal less often.

8. Plant during rainy season and or winter when the watering requirements are lower.

9. Check your water meter and bill to track your water usage.

10. Always water during the early morning hours, when temperatures are cooler, to

minimize evaporation.

11. Wash your produce in the sink or a pan that is partially filled with water instead of

running water from the tap.

12. Use a layer of organic mulch around plants to reduce evaporation and save

hundreds of liters of water a year.

13. Use a broom instead of a hose to clean your driveway and sidewalk and save up to

303 liters of water every time.

14. If your shower can fill 4 liters bucket in less than 20 seconds, and then replace it

with a water-efficient showerhead.

15. Collect the water you use for rinsing produce and reuse it to water houseplants.

16. Water your lawn in several short sessions rather than one long one. This will allow

the water to be better absorbed.

17. We’re more likely to notice leaky faucets indoors, but don’t forget to check outdoor

faucets, pipes, and hoses for leaks.



18. Only water your lawn when needed. You can tell this by simply walking across your

lawn. If you leave footprints, it’s time to water.

19. When you shop for a new appliance, keep in mind that one offering several

different cycles will be more water and energy-efficient.

20. Time your shower to keep it under 5 minutes. You’ll save up to 3785 liters a month.

21. Install low-volume toilets.

22. When you clean your fish tank, use the water you’ve drained on your plants. The

water is rich in nitrogen and phosphorus, providing you with a free and effective

fertilizer.

23. Water small areas of grass by hand to avoid waste.

24. Put food coloring in your toilet tank. If it seeps into the toilet bowl, you have a leak.

It's easy to fix, and you can save more than 2271 liters a month.

25. Plug the bathtub before turning the water on, then adjust the temperature as the

tub fills up.

26. Use porous materials for walkways and patios to keep water in your yard and

prevent wasteful runoff.

27. Designate one glass for your drinking water each day. This will cut down on the

number of times you run your dishwasher/wash your utensils.

28. Instead of using a hose or a sink to get rid of paints, motor oil, and pesticides,

disposes of them properly by recycling or sending them to a hazardous waste site.

29. Install a rain shut-off device on your automatic sprinklers to eliminate unnecessary

watering.

30. Don’t use running water to thaw food.

31. Choose water-efficient drip irrigation for your trees, shrubs, and flowers. Watering

roots is very effective, be careful not to over water.

32. Grab a wrench and fix that leaky faucet. It’s simple, inexpensive, and can save 530

liters a week.

33. Cut back on the amount of grass in your yard by planting shrubs and ground cover

or landscaping with rock.

34. When doing laundry, match the water level to the size of the load.

35. Teach your children to turn the faucets off tightly after each use.

36. Remember to check your sprinkler system valves periodically for leaks and keep the

heads in good shape.

37. Before you lather up, install a low-flow showerhead. They’re inexpensive, easy to

install, and can save your family more than 1900 liters a week.

38. Soak your pots and pans instead of letting the water run while you scrape them

clean.

39. Don’t water your lawn on windy days. After all, sidewalks and driveways don’t need

water.

40. Water deeply but less frequently to create healthier and stronger landscapes.

41. Make sure you know where your master water shut-off valve is located. This could

save liters of water and damage to your home if a pipe were to burst.

42. When watering grass on steep slopes, use a soaker hose to prevent wasteful runoff.

43. To get the most from your watering time, group your plants according to their water

needs.

44. Remember to weed your lawn and garden regularly. Weeds compete with other

plants for nutrients, light, and water.



45. While fertilizers promote plant growth, they also increase water consumption.

Apply the minimum amount of fertilizer needed.

46. Avoid installing ornamental water features unless the water is being recycled.

47. Use a commercial car wash that recycles water.

48. Don’t buy recreational water toys that require a constant flow of water.

49. Turn off the water while you brush your teeth and save 15 liters a minute. That’s

760 liters a week for a family of four.

50. Encourage your school system and local government to help develop and promote a

water conservation ethic among children and adults.

51. Teach your family how to shut off your automatic watering systems so anyone who

is home can turn sprinklers off when a storm is approaching.

52. Set a kitchen timer when watering your lawn or garden with a hose.

53. Make sure your toilet flapper doesn’t stick open after flushing.

8.13 Energy Efficiency Measures in a Typical Household

8.13.1 Hot Water

Repair leaky faucets.

Reduce the temperature setting of your water heater to warm (500 C).

Add an insulating blanket to your water heater.

Install low-flow showerheads.

Wash clothes in warm or cold water using the appropriate water level setting for the

load.

Replace water heater, when needed, with an energy efficient model.

Major Appliances and Other Appliances

Maintain refrigerator at 2 to 50 C and freezer section at –15 0 C.

Maintain stand alone freezer at 0 F.

Choose a refrigerator/freezer with automatic moisture control.

Use toaster ovens or microwave ovens for cooking small meals.

Adjust the flame on gas cooking appliances so it’s blue, not yellow.

Replace a gas-cooking appliance with a unit with an automatic, electric ignition

system.

Run the dishwasher only with a full load of dishes.

Air dry dishes in a dishwasher.

Shut down home computers when not in use.

Select appliances (i.e., curling irons, coffee pots, irons) with time limited shut off

switches.

Replace aging major appliances, TVs and VCRs when needed, with energy

efficient models. Replacing a 1970s refrigerator with an energy efficiency

refrigerator. This can save over 2,000 kWh per year. This will also reduce

carbon dioxide emissions by over 2,000 pounds every year.



Increase Air Conditioner thermostat by 3 degrees F. This can save over 900 kWh

per year, annually and over 900 pounds of carbon dioxide each year. Depending

on the size of your home, you can save 3% on your cooling costs for every

degree you raise your thermostat in the summer. Raising the thermostat from

73 to 78 F degrees can reduce cooling costs by 15%.

Make sure your air conditioner is the proper size for the area you are cooling.

An air conditioner that is too large will use more electricity than needed; an air

conditioner that is too small will have to work harder to cool a space. The

recommended Air conditioners based on the room size are as follows:

Area To Be Cooled (sq. ft.) Capacity (BTU/HR)

100 to 150 5,000

150 to 250 6,000

250 to 300 7,000

300 to 350 8,000

350 to 400 9,000

400 to 450 10,000

450 to 550 12,000

500 to 700 14,000

700 to 1,000 18,000

Only run the washing machine, dryer, and dishwasher when you have full loads.

Cool only the rooms you use and utilize fans when the temperature is moderate.

Lighting

Turn off lights when not in use.

Use task lighting whenever possible instead of brightly lighting an entire room.

Install compact fluorescent lamps in the fixtures which receive high use. Replace

the five most frequently used incandescent light bulbs with compact fluorescent

bulbs. This will save over 500 kWh per year, and over 500 pounds of CO2.

It is proposed to provide CFL units in the common areas, bathrooms, and central green

area to conserve electricity by the project authorities. The average usage of 4 CFLs in

each dwelling, and the total energy savings from the project and the overall reduction

in pollutants is presented in the following table;

8.14 Risk Assessment and Disaster Management

Construction sites in general do not handle toxic and or hazardous chemicals in large

quantities, and the usage of the same is temporary for specific tasks. However the

construction activity has a number of hazards resulting injuries and fatalities, and are

not reported widely due to the unorganized nature of construction professions. The

proposed project shall ensure the safety of workers and equipment to reduce and



mitigate hazards. The hazards and mitigation measures due to various construction

activities, and hazards to specific professions of construction are discussed as follows;

Site planning and layout

Site planning is essential to ensure safety and health of workers, in urban work sites

which have space constraints. Site planning shall reduce and or help avoiding accidents

due to collision of men with material and equipment etc. It is essential to plan the

sequence of construction operations, access for workers on and around the site with

signage, location of work shops for welding, carpentary etc., location of first air facility,

adequate lighting for work areas, site security by provision of fence or barricades,

arrangements to keep the site tidy and for collection and removal of wastes.

Site tidiness

All the construction workers are briefed about the importance of keeping the site tidy,

by clearing the rubbish and scrap at the end of the day, to keep the work area clear of

equipment and material, by depositing the waste in a designated location, by cleaning

up spills of materials.

Excavation

Excavation for foundation and trenches involves removal of soil and rock. Excavation or

trenching plan shall consider underground services if any. The hazards related to

excavation are face collapse and injury or burial of workers by soil and rock, fall and slip

of people in excavated pits and trenches, and injury to workers due to falling material

or equipment. The precautions to be taken are protection of excavation faces by

support material, erection of shoring along trenches.

Urban areas have building properties adjacent to the developing site, in such cases it is

necessary to shore the face of adjacent property to avoid fall or collapse of neighboring

land or wall. Vehicular movement surrounding the excavated area needs to be

restricted so as to avoid face collapse, and possible injury to workers. Excavation areas

shall be provided with adequate lighting.

Scaffolding

One of the important and serious safety risk in construction activity is fall of person

from a height and fall of materials and objects from height resulting in injury to

workers. Scaffold is a supporting structure connecting two are more platforms used for

either storage of materials or as a work place. Guard rails and toe boards shall be

provided at every place where the height of scaffolding is more than 2 m. It shall be

ensured that scaffold is anchored and tied to the building, it is not overloaded with men

and material, it is examined (both bamboo or wood and rope) frequently for infection

by insects, and that timber, if used, is not painted.

Ladders

Ladders are most commonly used equipment, as it is readily available and inexpensive,

and is used widely. However the limitations of ladders are overlooked resulting in

injuries and fatalities. Ladders have limitations; allows only one person to work, climb,

and carry materials or work with one hand, restricts movement, should be secured all

the time either using ropes or other people. It is essential to secure the ladder before

use. The safe use of ladder involves; ensuring that there are no overhead power lines,



ladder extends at least one meter above the landing place, never use props to extend

the height of ladder, facing the ladder while climbing or descending, making sure foot

ware of ladder user is free of mud and grease, not to over balance or over reach and

using a hoist line instead of carrying materials.

Steel Erection

Steel erection of building frames requires construction work at heights and in exposed

positions. However planning at the design stage, setting the sequence of operations,

supervising during construction, and usage of personal protective equipment like safety

belts in addition to provision of safety nets, anchorage points etc.

Confined Spaces

Construction work in confined spaces like open manholes, sewers, trenches, pipes,

ducts etc. may have dangerous atmosphere due to lack of oxygen or due to presence of

flammable or toxic gases. Work confined space is always conducted under supervision,

with adequate safety measures like; checking the atmosphere in confined space before

entry, provision of rescue harness to everyone, involvement of minimum of two

persons – one person for monitoring and ready for rescuing if needed, provision of

safety equipment like atmospheric testing device, safety harness, torch light, first aid

equipment, fire fighting apparatus, and resuscitation equipment.

Vehicles

The construction area shall have multiples of vehicles moving material with in the site

and from out side the site. The most common causes of onsite traffic incidents are;

bad driving technique, carelessness, carrying unauthorized passengers, poor

maintenance of vehicles, site congestion, overloading, and uneven ground and debris.

It is proposed to ensure that all drivers have appropriate driving license, routes are

planned, marked and leveled, enlisting additional workers during reversing, switching

off the engine during idling, and periodic maintenance schedule for all vehicles.

Movement of materials – Cranes and Hoists

Cranes and hoists are used for movement of materials within the site. The operators of

these machines are qualified and the cabins will have a signal chart to understand the

signals given by site workers. The site workers are trained in signals for transmitting to

the operators of these machines. Stability of these machines and overloading are

major concerns while operating these machines, hence it is necessary to avoid

overloading, and to ensure structural stability of these machines before use. The

cranes will have safety hooks, and the workers are trained in using the same, and

criticality of the hook. In case of hoists, it will be ensured that a gate is provided at each

platform, travel of passengers is avoided, and platforms are always aligned with landing

points.

Lifting and Carrying

Construction work involves a lot of manual labour resulting in stress and injury to the

workers. It is proposed to provide wheel burrows, trolleys etc., to avoid manual

carrying of materials. In situations where manual lifting of materials is needed, the

workers are trained in safety related to correct lifting technique, throwing technique in

addition to provision of personal protective equipment.



Working positions tools and equipment

There is an increased reliance of tools and equipment in the construction industry in the

past 15 years resulting in reduced risk of physical exhaustion. However the equipment,

working positions in using the equipment have its own hazards, which need to be

avoided to reduce risks like musculoskeletal disorders. It will be ensured that workers

preferably work in sitting posture with necessary tools handy, to avoid physical

exertion, the right tools are provided, and carrying tools in pockets avoided, and worn

out tools are replaced in time. In case of power driven tools, the dangerous part of the

machinery is always covered, the tool is never left in operation when not in use, and

power is switched off immediately in case of any incident, to avoid physical injury to

workers.

Working Environment

Many chemical substances like adhesives, cleaning agents, floor treatments, fungicides,

cements, grouts, insulants, sealants, paints, solvents etc. Solvents are critical

substances which require due attention as they are flammable and or toxic in few cases.

The usage of these chemical substances is always ensured to follow the instructions

mentioned by the manufacturers. Solvents will not be used for removal of paints and

grease from skin. Personal protective equipment is provided by the proponent and or

the contractor and the site safety executive shall ensure the same. Construction sites

are also major sources of noise resulting in hearing impairment. Hence it will be

ensured that all emission sources are provided with mufflers or silencers, motors are

covered, machinery panels are secured and are not allowed to rattle, and noise

attenuating screens are provided to segregate noisy working areas, in addition to

provision of personal protective equipment. Gloves are used when using Vibration

causing equipment. Adequate lighting is provided in work areas to mitigate hazards.

Health Hazards on Construction Sites

Construction works involve various trades with variable times of operation.

Construction operations have a number of potential hazardous operations and resulting

in health hazards to workers. Exposure differs from trade to trade, from job to job, by

the day, even by the hour. Exposure to any one hazard is typically intermittent and of

short duration, but is likely to reoccur. A worker may not only encounter hazards

related to his profession, but also encounters hazards related to other professions in

the vicinity. This pattern of exposure is a consequence of having many employers with

jobs of relatively short duration and working alongside workers in other trades that

generate other hazards. The hazard severity is contingent on concentration and

duration of exposure in a specific construction work. A list of hazards present for

workers in various trades is presented in table 8.7.

Construction Hazards

Hazards for construction workers are typically of four classes: chemical, physical,

biological and social.

Chemical hazards

Chemical hazards are mainly due to inhalation of dusts, fumes, mists, vapours or gases,

although some airborne hazards may settle on and be absorbed through the intact skin

(e.g., pesticides and some organic solvents). Chemical hazards also occur in liquid or

semi-liquid state (e.g., glues or adhesives, tar) or as powders (e.g., dry cement). Skin

contact with chemicals in this state can occur in addition to possible inhalation of the

vapor resulting in systemic poisoning or contact dermatitis. Chemicals might also be

ingested with food or water, or might be inhaled by smoking.

Several illnesses have been linked to the construction trades, among them: Silicosis

among sand blasters and rock drill operators; Asbestosis (and other diseases caused by

asbestos) among asbestos insulation workers, steam pipe fitters, building demolition

workers and others; Bronchitis among welders, Skin allergies among masons and others

who work with cement: Neurologic disorders among painters and others exposed to

organic solvents.

Physical hazards

Physical hazards are present in every construction project. These hazards include noise,

heat and cold, radiation, vibration and barometric pressure. Construction work often

must be done in extreme weather conditions. The usage of machines for construction

is resulting in noise. The sources of noise are engines of all kinds (e.g., on vehicles, air

compressors and cranes), winches, paint guns, pneumatic hammers, power saws,

sanders, planers and many more. It affects not only the person operating the machine,

but all the workers close-by. This may not only cause noise-induced hearing loss, but

also may mask other sounds that are important for communication and for safety.

Pneumatic hammers, many hand tools and earth-moving and other large mobile

machines also subject workers to segmental and whole-body vibration. Heat and cold

hazards arise primarily because a large portion of construction work is conducted while

exposed to the weather, the principal source of heat and cold hazards. Heavy

equipment operators may sit beside a hot engine and work in an enclosed cab with

windows and without ventilation. Those that work in an open cab with no roof have no

protection from the sun. A shortage of potable water or shade contributes to heat

stress as well. The principal sources of non-ionizing ultraviolet (UV) radiation are the

sun and electric arc welding. Lasers are becoming more common and may cause injury,

especially to the eyes, if the beam is intercepted. Strains and sprains are among the

most common injuries among construction workers. These, and many chronically

disabling musculoskeletal disorders (such as tendinitis, carpal tunnel syndrome and low-

back pain) occur as a result of either traumatic injury, repetitive forceful movements,

awkward postures or overexertion. Falls due to unstable footing, unguarded holes and

slips off scaffolding and ladders are very common.

Biological hazards

Biological hazards are presented by exposure to infectious micro-organisms, to toxic

substances of biological origin or animal attacks. Excavation workers, for example, can



develop histoplasmosis, an infection of the lung caused by a common soil fungus. Since

there is constant change in the composition of the labour force on any one project,

individual workers come in contact with other workers and, as a consequence, may

become infected with contagious diseases-influenza or tuberculosis, for example.

Workers may also be at risk of malaria disease if work is conducted in areas where

these organisms and their insect vectors are prevalent.

Social hazards

Employment in construction sector is intermittent, and control over many aspects of

employment is limited because construction activity is dependent on many factors over

which construction workers have no control, such as the state of an economy or the

weather. Because of the same factors, there can be intense pressure to become more

productive. Since the workforce is constantly changing, and with it the hours and

location of work, and many projects require living in work camps away from home and

family, construction workers may lack stable and dependable networks of social

support. Features of construction work such as heavy workload, limited control and

limited social support are the very factors associated with increased stress in other

industries. These hazards are not unique to any trade, but are common to all

construction workers in one way or another.

Decreasing exposure concentration

Three general types of controls can be used to reduce the concentration of

occupational hazards. These are, from most to least effective: engineering controls at

source, environmental controls that remove hazard from environment, personal

protection equipment provided to the worker.

Engineering controls

Hazards originate at a source. The most efficient way to protect workers from hazards is

to change the primary source with some sort of engineering change. For example, a less

hazardous substance can be substituted for one that is more hazardous. Water can be

substituted for organic solvents in paints. Similarly, non-silica abrasives can replace

sand in abrasive blasting (also known as sand blasting). Or a process can be

fundamentally changed, such as by replacing pneumatic hammers with impact

hammers that generate less noise and vibration. If sawing or drilling generates harmful

dusts, particulate matter or noise, these processes could be done by shear cutting or

punching. Technological improvements are reducing the risks of some musculoskeletal

and other health problems. Many of the changes are straightforward-for example, a

two-handed screwdriver with a longer handle increases torque on the object and

reduces stress on the wrists.

Environmental controls

Environmental controls are used to remove a hazardous substance from the

environment, if the substance is airborne, or to shield the source, if it is a physical

hazard. Provision of flexible Local exhaust ventilation (LEV) may be used. The simple

and effective method for controlling exposure to radiant physical hazards (noise,

ultraviolet (UV) radiation from arc welding, infrared radiant (IR) heat from hot objects)

is to shield them with some appropriate material. Plywood sheets shield IR and UV



radiation, and material that absorbs and reflects sound will provide some protection

from noise sources. Major sources of heat stress are weather and hard physical

labour. Adverse effects from heat stress can be avoided through reductions in the

workload, provision of water and adequate breaks in the shade and, possibly, night

work.

Personal protection

When engineering controls or changes in work practices do not adequately protect

workers, workers may need to use personal protective equipment (PPE). In order for

such equipment to be effective, workers must be trained in its use, and the equipment

must fit properly and be inspected and maintained. Furthermore, if others who are in

the vicinity may be exposed to the hazard, they should either be protected or

prevented from entering the area.

Eating and sanitary facilities

A lack of eating and sanitary facilities may also lead to increased exposures. Often,

workers cannot wash before meals and must eat in the work zone, which means they

may inadvertently swallow toxic substances transferred from their hands to food or

cigarettes. A lack of changing facilities at a worksite may result in transport of

contaminants from the workplace to a worker’s home. It is proposed to provide

separate temporary canteen and changing place for employees.

8.14 RISK ASSESSMENT AND VULNERABILITY ANALYSIS

8.14.1 Classification of Disaster

Disaster can occur at any point of time. It is essential to consider the mitigation plan

and protection for all the society members during occurrence of a disaster. If the

society i.e. the tenants/ residents of the buildings are aware of the actions to be taken

during a disaster, then the effect of disaster can be reduced or avoided. Following types

of natural disaster can occur with a prior indication or without any prior indication.



Natural Disasters: Natural Disasters occur naturally with or without any prior indication

a. Earthquake

Earthquakes are usually caused when rock underground suddenly breaks along a fault.

This sudden release of energy causes the seismic waves that make the ground shake.

Building develops cracks, collapses when the intensity of earthquake is more and

prolonged. Probability of Occurrence: As per the earthquake zonation of India, the

proposed site falls under seismic zone II which is referred as least risk zone. Thus the

possibility and severity of the experiencing the earthquake apparently decreases.

Although there are no past records of this disaster in this region, earthquake of

intensity 3.0 and 5.0 on the Richter scale can occur in Zone II. Accordingly the measures

proposed are enumerated in the section of mitigation and preparedness.

Fig. Seismic Zone Map of India

b. Cloud Burst and flood due to heavy rainfall

A cloudburst is an extreme amount of precipitation, sometimes with hail and thunder,

which normally lasts no longer than a few minutes but is capable of creating flood

conditions. Sudden cloudburst can cause a flood to occur. This is one of the natural



disasters. During the thunderstorms, the air mass that goes up from the lower level

carries a certain amount of water in it. Sometimes that air current abruptly stops

moving and the water mass falls down forcefully on the surface of earth. This natural

phenomenon is known as cloudburst. Flooding may occur due to the following reasons

• If the rainwater does get the access to the natural stream or municipal drains

• Delay in water flow from all runoff towards the natural stream like river, nalla (or

sea).

• Slow discharge of water

• Flow diversion

• Chocked up drains, nallah, river bed

The proposed site does not fall in any flood prone areas. Even if heavy rain fall are

received, a well designed storm water drain is proposed as also there is a municipal

storm water drain of adequate capacity

c. Lightning Strike

Lightning can score a direct hit on a highrise building. It can strike the overhead power

line which enters the building, or a main power line that is blocks away. Lightning can

strike branch circuitry wiring in the walls of the building. Lightning can strike an object

nearby, such as a tree or the ground itself and cause a surge. Voltage surges can be

created by cloud to cloud lightning. A highly charged cloud which passes overhead can

also induce a voltage surge. Buildings are protected from lightning by metallic lightning

rods extending to the ground from a point above the highest part of the roof. A

lightning arrester is a device used on electrical power systems and telecommunications

systems to protect the insulation and conductors of the system from the damaging

effects of lightning. The typical lightning arrester has a high-voltage terminal and a

ground terminal. The conductor has a pointed edge on one side and the other side is

connected to a long thick copper strip which runs down the building. The lower end of

the strip is properly earthed. When lightning strikes it hits the rod and current flows

down through the copper strip. These rods form a low-resistance path for the lightning

discharge and prevent it from travelling through the structure itself.

Unnatural Disasters: These kinds of disasters generally occur due to human error or

negligence.

d. Fire

Fire is a hazard which is caused mainly due to human negligence. There are other

reasons like electrical short circuit, rain water seepage in electrical installations, gas

cylinder malfunctioning, domestic gas leakage which can cause fire disaster in a

residential building. A full proof fire fighting system is designed for the buildings which

meets all fire safety norms and has a mitigation plan to tackle the fire hazard.

During construction all safety precautions will be taken to handle the fire hazard.

During construction fire can break out due to following reasons; Electrical loose

connection, Electrical short circuit, Storage of Inflammable material like diesel, paint at

site, From cooking gas cylinders at labour hutment.



e. Post Occupancy:

The proposed project is designed with utmost care for all fire safety norms for its

residents and the building as a whole. The normal cause of fire in the proposed project

post-occupancy is LPG cylinders, loose connection to LPG cylinders, electrical short

circuit, loose plug tops used by residents, storage of highly inflammable material like

diesel, kerosene by residents, fire crackers in festival session etc. The building will be

constructed with all fire safety norms to mitigate such calamities during operation

phase of the building. Fire proof material will be used as per design for various

components of the building. Electrical cables and switches will be IS (Bureau of Indian

Standard) certified and will have the minimum fire rating to mitigate any fire hazard.

The cabling and jointing will be done by professional agencies to avoid any mistake

while installation.

f. Building collapse

To protect against building collapse, hardening of the buildings structural systems may

be required. Designers should balance the hardening of the building envelope so that

the columns, walls, windows and glazing have an approximately equal response for

damage/ injury. This is a multi disciplinary effort of the architect, structural engineer,

mechanical engineer and other design team members in order to achieve a balance

building envelope.

g. Vehicle Accidents

Traffic flow to and within the site needs to be maintained so that there are no

obstructions to existing traffic flow on access roads. Also, road side parking will be

avoided. The entry/ exit to the site will be with adequate curvature at kerbs so that

vehicles coming out/ entering the building do not impinge on road traffic directly.

Regular maintenance and upkeep of the internal roads within project site will ensure

smooth traffic flow

h. Security breach

Included in this category are Bomb Threat, riots & vandalism: Bomb threats could be

genuine or false and many a time they turn out to a hoax. Unscrupulous elements with

the intention of creating a panic tend to resort to such hoax calls. Confirmed militants

however resort to such deeds with the intention of destruction and strike terror. It

would therefore be prudent to assess the genuinity of bomb threats. The threats are

usually through phone calls, giving very little time to react or through mail, giving a

certain date of an explosion that could occur. It is very rare that the caller will identify

himself and the message sent through any messenger for fear of easy identification

i. Malfunctioning of Lifts

Regular maintenance of lifts and other BMS has to be conducted. There should be a

specific Committee appointed for maintaining the systems during the operation phase.

8.14.2 MITIGATION AND PREPAREDNESS

Periodic mock drills, training programs are conducted to ensure all occupants are aware

of the emergency procedures. The occupants at the time of occupation are provided

with an emergency management manual. All the floors of the building will have

designated fire escape, with designated fire escape path. Each floor will have a safety



warden, mainly volunteered from among residents and or a maintenance/security

person.

Emergency Mitigation Procedures: Evacuation

Safety warden will be designated who will guide evacuation in an orderly manner. On

hearing the siren in other wings the wing safety warden will guide the occupants for

evacuation by following the glow signage exit routes, as per the guidance given by

Incident controller. Follow fire escape route only. The emergency exit door and

emergency exit route will be clearly marked with a glow sign. Lifts are discouraged

from usage, and all occupants are advised to use fire straircase. All evacuees are

discouraged to carry any baggage/belongings to expedite evacuation. Everyone is

advised to use hand rail while descending the staircase to mitigate the hazard of trip

and fall

I. Following measures will be taken during construction to avoid fire hazard:

• Training of workers on fire hazards during construction

• Tool box talk to workers on fire hazard and dos and don’ts

• Constant check on electrical connections

• No loose connection

• All plugs should have plug-tops

• ELCBs for all circuits

• Fire extinguishers at site at various location

• Regular check on cooking facilities at labour hutment by project manager

• Separate storage for highly inflammable material like diesel, paint.

II. Following measures will be taken during operation phase to avoid fire hazard:

To protect the building and the residents from any fire hazard building will be equipped

with any one or combination of following installations.

Fire Alarm System Initiating Device(s) –

Initiates fire alarm signal. Examples: smoke detectors, heat detectors, sprinkler flow

switch, manual pull station.

Monitoring Device - Fire alarm panel, located in the building Fire Command Center

located on the ground floor.

Signaling Device - Alerts building occupants to the alarm. Audible and visual alarms

signal on all floors (general alarm system) or only on floors in the immediate vicinity of

fire (zoned alarm system) like alarm horns, strobe lights.

Lift Recall - Upon activation of a smoke detector in the lift lobby, the lift shaft, or the ma-

chine room, the lifts are recalled to the building lobby. For all other fire alarm activations

the lifts will continue to run as normal. Lifts are not to be used during a fire evacuation

because elevators may fail and trap occupants or the elevator shafts may act as chimneys,

allowing smoke to travel up the shaft and injure occupants.



Exits - Two exit stairwells are provided, which are entered into through self-closing fire-

rated doors.

Emergency Generator - On-site diesel engine generator is proposed even though the site

is located in Hyderabad which has assured power supply to cater to the needs in case of

load shut down. A generator will run for a minimum of eight-hours to power the fire and

life safety systems.

Sprinkler Systems - Sprinkler systems are designed to control fires while relatively

small. Each sprinkler head discharges separately once the heat in the room has melted

the shunt, thus allowing water to flow.

Portable fire extinguishers - Required to be installed on the wall and inspected or

serviced at least once a year. Portable fire extinguishers are designed to put out small

contained fires

III. Emergency Mitigation Procedure: Natural Calamities : EARTHQUAKE

What to do DURING an earthquake?

Drop, Cover, and Hold On! If you are not near a desk or table, drop to the floor against

the interior wall and protect your head and neck with your arms. Avoid exterior walls,

windows, hanging objects, mirrors, tall furniture, large appliances, and kitchen cabinets

with heavy objects or glass. Do NOT run outside

Stop driving if you're in a safe place, and if outside, go into an open area. Don't attempt

to go outside if you're not in a position to do so--you could be injured by falling debris.

When the earthquake is over, be sure to wear shoes to avoid broken glass. If you smell

gas, turn off the main gas line and get out of the building. And don't forget--aftershocks

do occur, so don't assume the damage is done after the main shock has ended

EVACUATION

Emergency controller, incident controller and nominated fire safety wardens would play

a similar role as that in case of fire. Immediate evacuation of the building will be

absolutely necessary in major emergencies.

During earthquake following measures should be taken:

• At first few seconds residents should stay calm and open doors for easy access

• After the tremor subsides, Managing Committee shall instruct the residents for safe

evacuation of the building

• Building Lift should not be used and main power supply should be shut

• Intimate the external authorities like Fire Brigade for rescue operation

• Residents who are safe should be moved out of the building to a safer relief location

• If people are buried in debris, relief agencies should be called for safe rescue of the

people

• Arrange for relief and rehabilitation space

• Arrange for medical assistance, food.

• Residents should not drive during earthquake

• Residents should not move closer to any electrical pole or line while evacuation

process



IV. Measures to be taken during Flood/ Cloudburst

• Managing committee should arrange for safe evacuation of the residents

• Intimate the external authorities as mentioned in this plan

• Managing committee, Building Manager, Security personnel should guide the

way towards safe evacuation of the building.

• Arrange for relief and rehabilitation space

• Arrange for medical assistance, food.

• Residents should not drive during flood

• Residents should not move closer to any electrical pole or line while evacuation

process

• Switch off the main power supply of the building

V. SOCIAL CALAMITIES:

The following preparedness is recommended to handle bomb threats :

• Try to identify the caller and take as much information as possible

• Inform emergency controller to call police and get their guidance for further action.

The local police station to be intimated immediately on receipt of such calls. The

police is trained to handle such threats and have access to special bomb detection and

disposal squads

• Human life is most important and on receipt of such threats, emergency controller

will take a call to evacuate the site with the employees assembling at the site

emergency assembly point. All employees will be clearly informed about the threats

and panic will be minimized.

• Follow the evacuation instruction given by wing safety warden on public address

system

VI. OTHER EMERGENCIES : GAS LEAK

Do’s & don’t in case of gas leak :

• If you smell gas, DO not smoke or strike matches or use mobile phone

• Do not turn electrical switches on or off.

• Do open doors & windows.

• Do keep people away from the affected areas.

• Do close burner and regulator knobs

• If there is a leak from the cylinder, remove the cylinder to a safer place and call for

help from the nearest authorized dealer.

• Immediately inform the wing warden and follow his instructions.

• Follow the evacuations given by the wing warden or IC

• Evacuate the building at the earliest

• Emergency controller to inform fire brigade, gas agency for further guidance and

action.

• Return to the building when normalcy is restored by EC and instructed to do so
