2.2.1.1 Storm water drains: Storm water drains will be provided all over the site tomeet the expected increase in the runoff during rainy seasons due to the imperviousnature of the roads and other paved areas. The site is uneven and it is proposed tomaintain the levels as much as possible.

For each plot rainwater pipes shall be designed for rainfall intensity of 40mm/hour fromterrace floor to be harvested by storm water sumps adjacent to each building, excessdisposed to external storm water lateral drain running adjacent to the periphery of thecampus. The storm water drain has been worked taking into consideration the siteprofile (contour). The Rainwater Harvesting Structures is shown in fig 2.4.

The rainwater collected from the building and from the other surfaces of the plot isharvested by sump overflow being discharged to this storm water drains. Before thestorm water enters the sump I shall be passed through silt trap & grease trap forremoval of silt & oil if any. Harvested water shall be used for landscaping & for domesticuse.

Storm water drains will be provided all over the site to meet the expected increase inthe runoff during rainy seasons due to the impervious nature of the paved areas. Thesite is uneven and it is proposed to maintain the levels as much as possible, hencestorm water outlets from the site are anticipated. The expected runoff is calculated forthe design of the storm water management is presented in following table 2.3.

Rainwater Harvesting:The quantity of rainwater, which can be harvested, depends upon the annual rainfall,the area of the plot (catchment area) and soil characteristics. The amount of waterinfiltrated into soil varies with the condition of soil surface and the moisture content ofthe soil at the time of rainfall. The total amount of water infiltered depends on theinfiltration opportunity time, which depends mainly on the slope of the land and thefield structure like contour bunds, terraces and other structures, which tend to hold therunoff water over long periods on the land surface.

Sewage treatment plant based on Fluidized Aerobic Bio Reactor (FAB) technologyPROCESS DESCRIPTION:The raw sewage will be collected in a collection sump and pumped to mechanical barscreen chamber for removal of large floating matter followed by grit removal in GritChamber. The raw sewage will then be collected in an equalization tank forhomogenization of hydraulic load. The tank contents will be kept in suspension bymeans of course bubble serration through pipe grid. The equalization tank, with airflow indicator for continuous monitoring of air supply to the tank in order to avoidseptic conditions, will be covered from top (RCC or FRP) to avoid nuisance. Theequalized effluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) inseries where BOD/COD reduction can be achieved by virtue of aerobic microbialactivities. The oxygen required will be supplied through coarse air bubble diffusers.The bio-solids formed in the biological process will be separated in the down streamTube Settler. The clear supernatant will gravitate to the chlorine contact tank wheresodium 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 becollected in a sludge sump and then pumped to sludge drying bed for de watering. Thedried 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 FABreactor 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 alot of monitoring. Scarcity of open space and rising land a power costs have forced theindustries to look our for space saving, compact and efficient treatment options. Thishas led to the development attached growth processes where the bio mass is retainedwithin the aeration tank obviating the need for recycle. These plants are not onlycompact 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 specificbiofilm surface area culminated in the most advanced technology of aerobic biologicalfluidized bed treatment where the biofilm (biomass) grows on small carrier elementsthat move along with the water in the reactor. The movement is normally caused byaeration in the aerobic version of the reactor.

The reactor combines all the advantages and best features of Trickling filters, Rotatingbiological contractors, activated sludge process and submerged fixed film reactors whileeliminating the drawbacks of these systems. The plants are more compact and moreenergy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up withsmall carrier elements. The elements are made up of special grade PVC orpolypropylene 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 biomasssuch that they can fluidize using an aeration device. A biofilm develops on theelements, which move along the effluent in the reactor. The movement within thereactor is generated by providing aeration with the help of diffusers placed at thebottom of the reactor. Then thin biofilm on the elements enables the bacteria to actupon the biodegradable matter in the effluent and reduce the BOD/COD content in thepresence of oxygen available from the air that is used for fluidization.

2.2.2.1 Water RequirementThe water required for this project is in the order of 35640 m3 for the entire projectimplementation period. The peak demand for water may be 200 m3/day, howevertypical daily consumption will be in the order of 100 m3/day. The required water will bedrawn from ground water sources. The project authorities explored the possibility ofusing treated wastewater to meet partial requirement of water and could not identify areliable source. The water supply and plumbing will be optimized and low waterconsuming faucets and flush tanks will be used to conserve water.

2.2.2.2 Construction DebrisThe construction debris consists of various types of materials. The construction debriswill be in both hazardous and non-hazardous categories. The hazardous debris consistsof empty containers of adhesives, thinners, paints, and petroleum products. Theseempty containers will be sold to authorized recyclers. The non hazardous wastescontain 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 inthe order of 2%. Construction debris containing bricks, demolished RCC will be used forland filling in the place of sub grade.

2.2.2.3 PaintsAll the paints used in the premises will be ensured to have an albedo of at least 0.4 toincrease the reflectivity and reduce the heat dissipation and heat island effects.

2.2.2.4 Work Force:The labor/work force requirement is approximately 8000 man-days of various skilledand unskilled employees. Sufficient labor force and skilled employees are available, asHyderabad 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 1000 people. Thelabor force will be provided with temporary toilet facilities connected to a septic tankfollowed by sewer lines. The water requirement for the labor force will beapproximately 500 lt/day.

2.2.2.5 Material preparation and transportMost of the construction material except aggregate will be drawn from outside. Thematerial will be transported by trucks and the approximate number of truck trips are600. The material transport within the site will be facilitated by 5 no. of trippers.

2.2.2.6 Batching PlantThe required concrete will be prepared in a batching plant to be located temporarily inthe site so as to maintain the quality and reduce the lead distance. The capacity of thebatching plant will be 20 m3 to 30 m3/hr. The raw mix design (Cement: sand: coarseaggregates: water: admixture) is stored in electronic panel board and the quantities areweighed automatically as per the design mix. Aggregates in the sizes of 10 mm, 20 mmis stacked in separate bins and these materials are loaded into the hopper by scrapperand load cells. Cement is provided to the mix through silos (30 MT to 40 MT capacity)with the help of screw conveyor. Measured quantity of water and admixture is fed intohopper though load cells. In the hopper coarse aggregates, fine aggregates, cement,water and admixture gets mixed in required quantities by rotary motion of the mixerand 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. Theentire operation is closed and there is no scope of fugitive dust as the operation is wetin nature.

2.2.2.7 Stone CrusherThe required aggregate will be drawn from within the site from a temporary stonecrusher. The capacity of the stone crusher is 100 tons/hour. The stone crusher will usethe rocky boulders removed during the cut operations and used for the production ofaggregates of various sizes. The main raw material is boulders obtained from within thesite during clearing operations of the land and conveyed by tippers & dumpers to theplant site. All the crushing units are mobile and electrically operated. The boulder ischarged into the hopper with help of dumper. The boulders are crushed and screenedto required size with help of screens and carried by belt conveyors to the storage yard.The dust and the aggregate of less than 8.5 mm size will be used for road constructionand as sub base for flooring purpose instead of sand. All the silos and the conveyor beltswill be covered and the transfer points will be provided with water sprinkling. Thewater requirement for this plant is approximately 5 cum/day.

5.0 ENVIRONMENT MANAGEMENT PLAN

The M/s Aurobindo Pharma Limited envisaged constructing Commercial OfficeBuilding. The project is envisaged to develop 1.4770 hectares of land in Plot no. 30/C,Survey no. 83/1, Raidurg Panmakhta, Serilingamapally Municipality, Ranga ReddyDistrict.

5.1 PROJECT DETAILSThe project will be spread over an area of 1.4770 hectares in Plot no. 30/C, Survey no.83/1, Raidurg Panmaktha, Serilingamapally Municipality, Ranga Reddy District. The landbelongs to Telangana State Industrial Infrastructure Corporation Limited (TSIIC). Thesite is surrounded by open land in North and west directions. An existing 45 m wideroad in Northeast direction connecting Mind space Cross roads and 30 m wide road insouth direction connecting Mind space Cross roads and Old Mumbai Highway. Thenearest railway station is the Hi-tech City railway Station at a distance of 4.0 km.

5.2 MAJOR FINDINGS OF THE EIAAn EIA was conducted and the major findings of the EIA study are presented below

5.3 Environmental ImpactsImpact on Physical ResourcesConstruction of proposed project requires huge quantities of natural resources likesand, sub grade and aggregate, and materials produced from natural resources likebricks, cement and steel. The material shall be drawn from local sources, and the leaddistances range from 1 – 250 km. The impacts on physical resources of sand will beirreversible while bricks will be brought from kilns which use Coal ash. The materialrequirement of steel, cement etc. will be purchased from manufacturers with in state.Hence, no major impacts on physical resources as regards the availability andprocurement of construction material are anticipated due to the project.

Impacts on Air QualityImpacts on air quality during construction stage are likely to be due to operation ofconstruction yards, material transport on trucks and fugitive emissions from theconstruction sites. The model results for occupation stage show slight increase in theair quality and in worst concentrations are falling within the site, and the results arewith in the prescribed limits. Mitigation measures required for offsetting the air qualityimpacts are presented in the table 8.1 Environment Management and Action Plan.

Impacts on Noise QualityImpacts on noise quality during construction stage will be significant. Hence theconstruction near the habitation is proposed only during daytime. The impacts duringoccupation stage will be on the plots near to the main entrance. Construction workerswill be provided with protection equipment to guard against the noise impacts. Noisemitigating measures will be suggested for construction equipment and DG sets.



Impact on FloraThe project site and its surroundings do not form a habitat to any endangered flora.There are no trees within the project site due to anthropogenic pressures. The projectwill enhance the aesthetics of the site due to the provision of avenue plantation andcentral greening. This would ensure minimum impact on flora.

Impact on FaunaAs there are no endangered species of wild life in and around the project site, it is likelyto have minimal impact. The avifauna will find abode on the trees proposed to beplanted. This would enhance the aesthetics of the area. Pet animal faeces should notenter the storm water drains.

Impact on Land useThere is no land acquisition for this project. The land use of the site fallow land andclassified as commercial by HMDA. However the topography of the land being rockyplains involves cut and fill operation. Erosion and sedimentation are impactsanticipated during construction. Mitigation measures shall be adopted to avoid thesame. The area development would increase the housing/commercial activity in thesurroundings, which is a positive impact, as barren lands will be used for productiveusage, and the negative impacts will be pressure on the infrastructure facilities.

Impact on Surface Water ResourcesThe degradation of water quality can occur during construction phase from increasedsediment load into watercourses near the construction site. Suitable mitigationmeasures proposed, as part of the EMP will ensure that the residual impacts areminimal. Storm water runoff would increase due to the increase in impervioussurface, and rainwater harvesting structures will be provided as mitigation measure.The design of the storm water drain will consider the additional runoff. The urbanstorm water joining the storm water drains may carry pollutants from impervioussurfaces.

Impact on Ground Water ResourcesGround water shall be drawn during construction, and will be used to augment themunicipal supply during non-monsoon season if necessary. Exploitation of groundwater will have an impact and the same shall be restricted to ensure resourceconservation. This impact will be marginal, as the ground water will not be drawncontinuously.

Impact on InfrastructureThe infrastructure of communication available at present is saturated; the proposal tolay new connectors between HMDA, GHMC will reduce the congestion. Thedevelopment in combination with this project activity will have marginal impact. Theadditional requirement of power would increase the pressure on the electricalinfrastructure and requires additional power generation in the overall context.

Impact on Human Use ValuesThe dominant land use in the area is residential, and expected commercial space willincrease the pressure on the residential localities. There is no additional requirement



and or acquisition of land. The provision of public lung space in the project and othercommunity facilities will reduce the additional transport required availing the facilities.The project authorities will provide road safety measures to reduce risk of accidents inthe internal roads. The impact on Human use values is marginal.

5.4 ENVIRONMENT MANAGEMENT MEASURES PROPOSEDA description of the various management measures during the various stages of theproject is provided in the following sections.

5.4.1 Pre-construction stageDuring the design and preconstruction stage the management proposes to comply withthe regulations of town planning, explore the availability of sufficient resources, provideplantation and sink bore wells after obtaining the necessary permission.

5.4.2 Construction stageThis will be the most crucial and active stage for the Environment Management Plan. Inaddition to the monitoring of the construction activity itself to the pollution levelswithin permissible limits, mitigation and enhancement measures for water resourceswill go on simultaneously as the construction progresses. To facilitate implementationof the enhancement and mitigation measures suggested working drawings of the samewould be prepared after completion of detailed project report. In addition, the needfor a balanced evaluation and planning for risks associated with construction activitiesrelated to housing and commercial project will be part of the Supervising Contractorsresponsibility.

The resource conservation by way of identification of materials and construction debrisrecycle/disposal will be formulated by the supervising consultants. The responsibility ofenvironment management plan lies with the project authorities that would implementthe plan in consultation with other consultants, by including appropriate provisions inthe contract/sub contract documents and providing the necessary facilities.

5.4.3 Operation stageThe environment management plan will be implemented by ownersassociations/societies, where project authorities are co-opted as members, and whilethe management plan related to the utilities like roads, street lighting and commonopen spaces lies with the TSIIC. The management in operation stage will essentiallyentail maintenance of sewage treatment plant, maintenance of utilities, and monitoringactivity in the project site. Monitoring for pollutants specified in the Monitoring Planwill serve the two purposes. In addition to checking the efficacy of theprotection/mitigation/enhancement measures implemented, this will help verify orrefute the predictions made as a part of the impact assessment. Thus, it will complete avery important feedback loop for the project.

The measures adopted and/or to be adopted during different stages of the project havebeen detailed in table 5.1.

5.5 IMPLEMENTATION ARRANGEMENTSThe responsibility of implementing the mitigation measures lies with M/s AurobindoPharma Limited during design and construction stages while the responsibility lies withthe M/s Aurobindo Pharma Limited and the TSIIC during occupation stage. Allconstruction activities taken up by the project authorities will be supervised by theSupervision Consultant (SC). Implementation schedule will be worked for phase wiseimplementation of the mitigation measures after completion of detailed designs. In thepre-construction phase of the project the supervision consultants shall review the EMPto identify environmental and social issues and arrive at a suitable strategy forimplementation. The activities to be carried out and the target dates will be worked outafter completion of detailed designs.

5.6 INSTITUTIONAL STRENGTHENINGThe management of M/s Aurobindo Pharma Limited will evaluate the organizationalstructure with respect to inadequacies in implementing the environment managementplans. The project is typical as the responsibility of management lies with theowners/residents during occupation stage. The owners form a cooperativesociety/association to manage the utilities and common areas in a normal case. TheM/s Aurobindo Pharma Limited will have little role to play in environmentmanagement. Hence it is suggested to explore the possibility of co-opting a memberfrom M/s Aurobindo Pharma Limited into these societies so as the spirit of environmentmanagement plan is not lost. The common areas, electrical supply, street lighting, openspace of central green will be taken over and managed by the Municipality andTRANSCO. The role of residents is limited to being stakeholders with little say in theday-to-day matters; the town planning agencies and the government must address thisissue.

The Environment Management Plan envisages on-site monitoring of constructionactivities for environmental pollution and will involve collection of samples and theirsubsequent analysis. For this purpose two chemists would be required especially whenthe implementation of the two phases goes on simultaneously. Induction of two more



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

5.7 TRAININGThe existing supervising staff and the additional staff have to be trained to effectivelycarry out.

Co-ordinate, with supervision consultants and contractors on compliancemonitoring 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 projects; Liase with State and Government of India on fiscal policies to reduce environmental

pollution from activity.

5.8 ENVIRONMENTAL MONITORING5.8.1 IntroductionThe environmental monitoring programme provides such information on whichmanagement decision may be taken during construction and occupation phases. Itprovides basis for evaluating the efficiency of mitigation and enhancement measuresand 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.

5.8.2 ObjectivesThe 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.

5.8.3 MethodologyMonitoring 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 specifiedare discussed below.

5.8.4 Ambient Air Quality (AAQ) MonitoringAmbient air quality parameters recommended for road transportation developmentsare Particulate Matter (PM10), Particulate Matter (PM2.5), Oxides of Nitrogen (NOX),Sulphur Dioxide (SO2) and Lead (Pb). These are to be monitored at designated locationsstarting from the commencement of construction activity. Data should be generatedover three days at all identified locations in accordance to the National Ambient AirQuality Standards (table 5.2) location, duration and the pollution parameters to bemonitored and the responsible institutional arrangements are detailed out in theEnvironmental Monitoring Plan.

5.8.6 Noise Level MonitoringThe measurements for monitoring noise levels would be carried out at all designatedlocations in accordance to the Ambient Noise Standards formulated by Central PollutionControl Board (CPCB) in 1989 (refer table 5.4) Sound pressure levels would bemonitored on twenty-four hour basis. Noise should be recorded at “A” weightedfrequency using a “slow time response mode” of the measuring instrument. Thelocation, duration and the noise pollution parameters to be monitored and theresponsible institutional arrangements are detailed in the Environmental MonitoringPlan (Table 5.5)

5.9 REPORTING SYSTEMReporting system provides the necessary feedback for project management to ensurequality of the works and that the program is on schedule. The rationale for a reportingsystem is based on accountability to ensure that the measures proposed as part of theEnvironment Management Plan get implemented in the project.

The reporting system will operate linearly with the contractor who is at the lowest rungof the implementation system reporting to the Supervision Consultant, who in turn shallreport to the M/s Aurobindo Pharma Limited All reporting by the contractor andSupervision Consultant shall be on a quarterly basis. The M/s Aurobindo PharmaLimited shall be responsible for preparing targets for each of the identified EMAPactivities. All subsequent reporting by the contractor shall be monitored as per thesetargets set by the M/s Aurobindo Pharma Limited before the contractors move on tothe site. The reporting by the Contractor will be a monthly report like report of progresson construction and will form the basis for monitoring by the M/s Aurobindo PharmaLimited either by its own Environmental Cell or the Environmental Specialist hired bythe 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.



5.10 ENVIRONMENTAL MANAGEMENT BUDGETThe environmental budget for the various environmental management measuresproposed in the EMP is detailed in table 5.6. There are several other environmentalissues that have been addressed as part of good engineering practices, the costs forwhich has been accounted for in the Engineering Costs. Moreover, since environmentalenhancements have not been finalized at this stage, the table projects the typical costsaspect wise and the detailed cost estimate is presented in Annexure A.

5.11 Horticultural and Landscaping Works(a) ScopeThe Horticultural and Landscaping works may be entrusted to a contractor or may betaken by the horticulture department of the M/s Aurobindo Pharma Limited., It wouldgenerate local employment if the plantation, upkeep and maintenance of the green beltis entrusted to local VSS bodies. Detailed drawings and designs of landscaping will bedrawn after completion of the detailed designing. The following precautions must betaken while undertaking horticulture and landscaping works. The M/s AurobindoPharma Limited project will have greenery by way of avenue plantation and centralgreen. 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) MaterialsPlant MaterialsPlant 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 ordisfigurement.

All plant materials shall be healthy, sound, vigorous, free from plant diseases, insect’spests, of their eggs, and shall have healthy, well-developed root systems. All plants shallbe hardy under climatic conditions similar to those in the locally of the project. Plantssupplied shall to confirm to the names listed on both the plan and the plant list. Noplant material will be accepted if branches are damaged or broken. All material must beprotected from the sun and weather until planted.

Any nursery stock shall have been inspected and approved by the EnvironmentalSpecialist or the Engineer.

All plants shall conform to the requirements specified in the plant list. Except thatplants larger then specified may be used if approved, but use of such plants shall notincrease the contract price. If the use of the larger plant is approved, the spread of rootor 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 localitycontaining 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 anyother objectionable extraneous matter or debris. It shall contain no toxic material. Notopsoil shall be delivered in a muddy condition. It shall have pH value ranging between6 and 8.5.

FertilizerMeasurement of sludge shall be in stacks, with 8% reduction for payment. It shall befree from extraneous matter, harmful bacteria insects or chemicals. (Subjected tosafety norms)

Root SystemThe root system shall be conducive to successful transplantation. While necessary, theroot-ball shall be preserved by support with Hessian or other suitable material. On soilswhere retention of a good ball is not possible, the roots should be suitably protected insuch a way that the roots are not damaged.

ConditionTrees and shrubs shall be substantially free from pests and diseases, and shall bematerially undamaged. Torn or lacerated roots shall be pruned before dispatch. Noroots shall be subjected to adverse conditions such as prolonged exposure to dryingwinds or subjection to water logging between lifting and delivery.



(c) Supply and SubstitutionUpon submission of evidence that certain materials including plant materials are notavailable at time of contract, the contractor shall be permitted to substitute with anequitable adjustment of price. All substitutions shall be of the nearest equivalentspecies and variety to the original specified and shall be subjected to the approval ofthe Landscape Architect.

(d) PackagingPackaging shall be adequate for the protection of the plants and such as to avoidheating or drying out.

(e) MarkingEach specimen of tree and shrub, or each bundle, shall be legibly labelled with thefollowing particulars: Its name. The name of the supplier, unless otherwise agreed. The date of dispatch from the nursery.

(f) Tree PlantingPlants and ShrubsTrees should be supplied with adequate protection as approved. After delivery, ifplanting is not to be carried out immediately, balled plants should be placed back toback and the ball covered with sand to prevent drying out. Bare rooted plants can beheeled in by placing the roots in prepared trench and covering them with earth, whichshould be watered into, avoid air pockets round the roots. Trees and shrubs shall beplanted as shown in architectural drawings and with approval of site supervisionengineer.

Digging of PitsTree pits shall be dug a minimum of three weeks prior to backfilling. The pits shall be120 cm in diameter and 120 cm deep. While digging the pits, the topsoil up to a depthof 30 cm may be kept aside, if found good (depending upon site conditions), and mixedwith the rest of the soil.

If the side of the below, it shall be replaced with the soil mixture as specified furtherherein. If the soil is normal it shall be mixed with manure; river sand shall be added tothe soil if it is heavy. The bottom of the pit shall be forked to break up the subsoil.

Back FillingThe soil back filled watered through and gently pressed down, a day previous toplanting, to make sure that it may not further settle down after planting. The soil shallbe pressed down firmly by treading it down, leaving a shallow depression all rounds forwatering.

PlantingNo tree pits shall be dug until final tree position has been pegged out for approval. Careshall 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. Planttrees at the original soil depth; soil marks on the stem is an indication of this and shouldbe maintained on the finished level, allowing for setting of the soil after planting. Allplastic and other imperishable containers should be removed before planting. Anybroken 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. Bareroots should be spread evenly in the planting pit; and small mound in the centre of thepits on which the roots are placed will aid on even spread. Soil should be placed aroundthe roots, gently shaking the tree to allow the soil particles to shift into the root systemto ensure close contact with all roots and prevent air pockets. Back fill soil should befirmed 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 byvolume) 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 ofwater.

StakingNewly planted trees must be held firmly although not rigidly by staking to prevent apocket forming around the stem and newly formed fibrous roots being broken bymechanical 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. Suitablefor small bare- rooted or Ball material

(d) For plant material 3m to 4.5m high with a single stem a three- wire adjustable guysystem may be used in exposed situations.

The end of stake should be pointed and the lower 1m to 1.2m should be coated with anon-injurious wood preservative allowing at least 150mm above ground level.

TyingEach 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 andstake. The tree should be secured at a point just below its lowest branch, and also justabove ground level; normally two ties should be used for tree. These should beadjusted or replaced to allow for growth.



WateringThe Landscape Contractor should allow for the adequate watering in of all newlyplanted trees and shrubs immediately after planting and he shall during the followinggrowing season, keep the plant material well watered.

FertilizingFertilising shall be carried out by application in rotation of the following fertilisers, every15 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- grownplants is essential.

(g) Shrub Planting In Planter BedsAll 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 (8parts of stacked volume of earth after reduction by 20%: 1 part of stacked volume ofsludge after reduction by 8%.)Tall shrubs may need staking, which shall be provided if approved by the contractingconsulting engineer, depending upon the conditions of individual plant specimen.

For planting shrubs and ground cover shrubs in planters, good earth shall be mixed withsludge in the proportion as above and filled in planters.

Positions of planters shall be planted should be marked out in accordance with thearchitectural drawing. When shrubs are set out, precautions should be taken to preventroots drying. Planting holes 40 cm in diameter, and 40 cm deep should be excavated forlonger shrubs. Polythene and other non-perishable containers should be removed andany badly damaged roots carefully pruned. The shrubs should then be set in holes sothat 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. Theremainder of the soil can then be returned and again firmed by treading.

(h) GrassingPreparationDuring 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 tothe actual sowing. Regular watering shall be continued until sowing by dividing the areainto 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 ensuredthat the soil has completely settled.



SoilThe soil itself shall be ensured to the satisfaction of Landscape Architect to be a goodfibrous loam, rich in humus.

Sowing the grass rootsGrass 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 watersprayed over the same after keeping the stock in place protected from sun and drywinds.

Grass stock received at site may be stored for a maximum of three days. In casegrassing for some areas is scheduled for a later date fresh stock of grass roots shall beordered and obtained.

ExecutionSmall roots shall be dibbled about 5 cm apart into the prepared grounds. Grass willonly be accepted as reaching practical completion when germination has provedsatisfactory and all weeds have been removed.

MaintenanceAs soon as the grass is approximately a 3cm high it shall be rolled with a light woodenroller – in fine, dry weather – and when it has grown to 5 to 8 cm, above to groundweeds 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 wellbroken sludge manure shall be applied when the grass is sufficiently secure in theground to bear the mowing machine, the blades must be raised an inch above thenormal level for the first two or three cuttings. That is to say, the grass should be cut sothat it is from 4 to 5 cm in length, instead of the 3 cm necessary for mature grass.

In the absence of rain, in the monsoon, the lawn shall be watered every ten daysheavily, soaking the soil through to a depth of at least 20 cm.

Damage failure or dying back of grass due to neglect of watering especially for seedingout of normal season shall be the responsibility of the contractor. Any shrinkage belowthe specified levels during the contract or defect liability period shall be rectified at thecontractor's expense. The Contractor is to exercise care in the use of rotary cultivatorand mowing machines to reduce to a minimum the hazards of flying stones andbrickbats. All rotary mowing machines are to be fitted with safety guards.

RollingA light roller shall be used periodically, taking care that the area is not too wet andsodden.

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



FertilizingThe area shall be fed once in a month with liquid manure prepared by dissolving 45gmsof ammonium sulphate in 5 litres of water.

WateringWater shall be applied at least once in three days during dry weather. Wateringwhenever done should be thorough and should wet the soil at least up to a depth of20 cm.

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

CultivatingThe Landscape Contractor shall maintain all planted areas within Landscape contractboundaries 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 approvedinsecticide or fungicide, pruning, and other horticulture operations necessary for propergrowth of the plants and for keeping the landscape sub-contract area neat inappearance.

Pruning and RepairsUpon completion of planting work of the landscape sub-contract all trees should bepruned and all injuries repaired where necessary. The amount of pruning shall belimited to the necessary to remove dead or injured twigs and branches and tocompensate for the loss of roots and the result of the transplanting operations. Pruningshall be done in such a manner as not to change the natural habit or special shape oftrees.

Tree GuardsWhere the tree guards are necessary, care should be taken to ensure that they do notimpede natural movement or restrict growth. Circular iron tree guards shall be providedfor 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) 3 Nos. 25x25x3mm angle iron verticals 2.00m longexcluding splayed outward at lower end up to an extent of 10 cms.

Plants with bare-roots should beheeled- in as soon as received or otherwise protected from drying out, and others setclosely together and protected from the wind. If planting is to be delayed for more thana week, packaged plants should be unpacked, the bundles opened up and each group ofplants heeled in separately and clearly labelled. If for any reason the surface of theroots becomes dry the roots should be thoroughly soaked before planting.

(j) Protective FencingAccording to local environment, shrubs shall be protected adequately from vandalismuntil established.

(l) CompletionOn completion, the ground shall be formed over and left tidy.

5.12 Water Conservation MeasuresWater conservation measures must be adopted during the occupation stage that wouldconserve the natural resource and also reduce the pressure on other users. A typicallist of water conservation measures are presented as follows;

Water Saving Measures1. There are a number of ways to save water and they all start with you.2. Check your sprinkler system frequently and adjust sprinklers so only your lawn is

watered and not the blocks, sidewalk, or street.3. Avoid planting turf in areas that are hard to water such as steep inclines and

isolated strips along sidewalks and driveways.4. Install covers on pools and check for leaks around your pumps.5. Use the garbage disposal less often.6. Plant during rainy season and or winter when the watering requirements are lower.7. Always water during the early morning hours, when temperatures are cooler, to

minimize evaporation.8. Wash your produce in the sink or a pan that is partially filled with water instead of

running water from the tap.9. Use a layer of organic mulch around plants to reduce evaporation and save

hundreds of liters of water a year.10. Use a broom instead of a hose to clean your driveway and sidewalk and save up to

302.833 liters of water every time.11. Collect the water you use for rinsing produce and reuse it to water interior plants.12. Water your lawn in several short sessions rather than one long one. This will allow

the water to be better absorbed.



13. We’re more likely to notice leaky faucets indoors, but don’t forget to check outdoorfaucets, pipes, and hoses for leaks.

14. Only water your lawn when needed. You can tell this by simply walking across yourlawn. If you leave footprints, it’s time to water.

15. Install low-volume toilets.16. Water small areas of grass by hand to avoid waste.17. Use porous materials for walkways and patios to keep water in your yard and

prevent wasteful runoff.18. 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.19. Instead of using a hose or a sink to get rid of paints, motor oil, and pesticides,

dispose of them properly by recycling or sending them to a hazardous waste site.20. Install a rain shut-off device on your automatic sprinklers to eliminate unnecessary

watering.21. Choose water-efficient drip irrigation for your trees, shrubs, and flowers. Watering

roots is very effective, be careful not to over water.22. Grab a wrench and fix that leaky faucet. It’s simple, inexpensive, and can save

529.958 liters a week.23. Cut back on the amount of grass in your yard by planting shrubs and ground cover

or landscaping with rock.24. Remember to check your sprinkler system valves periodically for leaks and keep the

heads in good shape.25. Don’t water your lawn on windy days. After all, sidewalks and driveways don’t need

water.26. Water deeply but less frequently to create healthier and stronger landscapes.27. 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.28. When watering grass on steep slopes, use a soaker hose to prevent wasteful runoff.29. To get the most from your watering time, group your plants according to their water

needs.30. Remember to weed your lawn and garden regularly. Weeds compete with other

plants for nutrients, light, and water.31. While fertilizers promote plant growth, they also increase water consumption.

Apply the minimum amount of fertilizer needed.32. Avoid installing ornamental water features unless the water is being recycled.33. Teach your employees how to shut off your automatic watering systems so anyone

can turn sprinklers off when a storm is approaching.34. Make sure your toilet flapper doesn’t stick open after flushing.35. Make sure there are aerators on all of your faucets.36. Next time you add or replace a flower or shrub, choose a low water use plant for

year-round landscape color and save up to 2081.976 liters each year.

5.13 Risk Assessment and Disaster ManagementConstruction sites in general do not handle toxic and or hazardous chemicals in largequantities, and the usage of the same is temporary for specific tasks. However theconstruction activity has a number of hazards resulting injuries and fatalities, and arenot reported widely due to the unorganized nature of construction professions. Theproposed project shall ensure the safety of workers and equipment to reduce and



mitigate hazards. The hazards and mitigation measures due to various constructionactivities, and hazards to specific professions of construction are discussed as follows;

Site planning and layoutSite planning is essential to ensure safety and health of workers, in urban work siteswhich have space constraints. Site planning shall reduce and or help avoiding accidentsdue to collision of men with material and equipment etc. It is essential to plan thesequence of construction operations, access for workers on and around the site withsignage, 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 tidinessAll 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 ofequipment and material, by depositing the waste in a designated location, by cleaningup spills of materials.

ExcavationExcavation for foundation and trenches involves removal of soil and rock. Excavation ortrenching plan shall consider underground services if any. The hazards related toexcavation are face collapse and injury or burial of workers by soil and rock, fall and slipof people in excavated pits and trenches, and injury to workers due to falling materialor equipment. The precautions to be taken are protection of excavation faces bysupport material, erection of shoring along trenches.Urban areas have building properties adjacent to the developing site, in such cases it isnecessary to shore the face of adjacent property to avoid fall or collapse of neighboringland or wall. Vehicular movement surrounding the excavated area needs to berestricted so as to avoid face collapse, and possible injury to workers. Excavation areasshall be provided with adequate lighting.

ScaffoldingOne of the important and serious safety risk in construction activity is fall of personfrom a height and fall of materials and objects from height resulting in injury toworkers. Scaffold is a supporting structure connecting two are more platforms used foreither storage of materials or as a work place. Guard rails and toe boards shall beprovided at every place where the height of scaffolding is more than 2 m. It shall beensured that scaffold is anchored and tied to the building, it is not overloaded with menand material, it is examined (both bamboo or wood and rope) frequently for infectionby insects, and that timber, if used, is not painted.

LaddersLadders are most commonly used equipment, as it is readily available and inexpensive,and is used widely. However the limitations of ladders are overlooked resulting ininjuries 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 allthe time either using ropes or other people. It is essential to secure the ladder beforeuse. 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 extendthe height of ladder, facing the ladder while climbing or descending, making sure footware of ladder user is free of mud and grease, not to over balance or over reach andusing a hoist line instead of carrying materials.

Steel ErectionSteel erection of building frames requires construction work at heights and in exposedpositions. However planning at the design stage, setting the sequence of operations,supervising during construction, and usage of personal protective equipment like safetybelts in addition to provision of safety nets, anchorage points etc.

Confined SpacesConstruction 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 offlammable or toxic gases. Work confined space is always conducted under supervision,with adequate safety measures like; checking the atmosphere in confined space beforeentry, provision of rescue harness to everyone, involvement of minimum of twopersons – one person for monitoring and ready for rescuing if needed, provision ofsafety equipment like atmospheric testing device, safety harness, torch light, first aidequipment, fire fighting apparatus, and resuscitation equipment.

VehiclesThe construction area shall have multiples of vehicles moving material with in the siteand from out side the site. The most common causes of onsite traffic incidents are;bad driving technique, carelessness, carrying unauthorized passengers, poormaintenance of vehicles, site congestion, overloading, and uneven ground and debris.It is proposed to ensure that all drivers have appropriate driving license, routes areplanned, marked and leveled, enlisting additional workers during reversing, switchingoff the engine during idling, and periodic maintenance schedule for all vehicles.

Movement of materials – Cranes and HoistsCranes and hoists are used for movement of materials within the site. The operators ofthese machines are qualified and the cabins will have a signal chart to understand thesignals given by site workers. The site workers are trained in signals for transmitting tothe operators of these machines. Stability of these machines and overloading aremajor concerns while operating these machines, hence it is necessary to avoidoverloading, and to ensure structural stability of these machines before use. Thecranes will have safety hooks, and the workers are trained in using the same, andcriticality of the hook. In case of hoists, it will be ensured that a gate is provided at eachplatform, travel of passengers is avoided, and platforms are always aligned with landingpoints.

Lifting and CarryingConstruction work involves a lot of manual labour resulting in stress and injury to theworkers. It is proposed to provide wheel burrows, trolleys etc., to avoid manualcarrying of materials. In situations where manual lifting of materials is needed, theworkers are trained in safety related to correct lifting technique, throwing technique inaddition to provision of personal protective equipment.



Working positions tools and equipmentThere is an increased reliance of tools and equipment in the construction industry in thepast 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 beavoided to reduce risks like musculoskeletal disorders. It will be ensured that workerspreferably work in sitting posture with necessary tools handy, to avoid physicalexertion, the right tools are provided, and carrying tools in pockets avoided, and wornout tools are replaced in time. In case of power driven tools, the dangerous part of themachinery is always covered, the tool is never left in operation when not in use, andpower is switched off immediately in case of any incident, to avoid physical injury toworkers.

Working EnvironmentMany chemical substances like adhesives, cleaning agents, floor treatments, fungicides,cements, grouts, insulants, sealants, paints, solvents etc. Solvents are criticalsubstances 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 instructionsmentioned by the manufacturers. Solvents will not be used for removal of paints andgrease from skin. Personal protective equipment is provided by the proponent and orthe contractor and the site safety executive shall ensure the same. Construction sitesare also major sources of noise resulting in hearing impairment. Hence it will beensured that all emission sources are provided with mufflers or silencers, motors arecovered, machinery panels are secured and are not allowed to rattle, and noiseattenuating screens are provided to segregate noisy working areas, in addition toprovision of personal protective equipment. Gloves are used when using Vibrationcausing equipment. Adequate lighting is provided in work areas to mitigate hazards.

Health Hazards on Construction SitesConstruction works involve various trades with variable times of operation.Construction operations have a number of potential hazardous operations and resultingin health hazards to workers. Exposure differs from trade to trade, from job to job, bythe day, even by the hour. Exposure to any one hazard is typically intermittent and ofshort duration, but is likely to reoccur. A worker may not only encounter hazardsrelated to his profession, but also encounters hazards related to other professions inthe vicinity. This pattern of exposure is a consequence of having many employers withjobs of relatively short duration and working alongside workers in other trades thatgenerate other hazards. The hazard severity is contingent on concentration andduration of exposure in a specific construction work. A list of hazards present forworkers in various trades is presented in table 5.7.

Construction HazardsHazards for construction workers are typically of four classes: chemical, physical,biological and social.

Chemical hazardsChemical 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 orsemi-liquid state (e.g., glues or adhesives, tar) or as powders (e.g., dry cement). Skincontact with chemicals in this state can occur in addition to possible inhalation of thevapor resulting in systemic poisoning or contact dermatitis. Chemicals might also beingested with food or water, or might be inhaled by smoking.

Several illnesses have been linked to the construction trades, among them: Silicosisamong sand blasters and rock drill operators; Asbestosis (and other diseases caused byasbestos) among asbestos insulation workers, steam pipe fitters, building demolitionworkers and others; Bronchitis among welders, Skin allergies among masons and otherswho work with cement: Neurologic disorders among painters and others exposed toorganic solvents.

Physical hazardsPhysical hazards are present in every construction project. These hazards include noise,heat and cold, radiation, vibration and barometric pressure. Construction work oftenmust be done in extreme weather conditions. The usage of machines for constructionis resulting in noise. The sources of noise are engines of all kinds (e.g., on vehicles, aircompressors 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, butalso may mask other sounds that are important for communication and for safety.Pneumatic hammers, many hand tools and earth-moving and other large mobilemachines also subject workers to segmental and whole-body vibration. Heat and coldhazards arise primarily because a large portion of construction work is conducted whileexposed to the weather, the principal source of heat and cold hazards. Heavyequipment operators may sit beside a hot engine and work in an enclosed cab withwindows and without ventilation. Those that work in an open cab with no roof have noprotection from the sun. A shortage of potable water or shade contributes to heatstress as well. The principal sources of non-ionizing ultraviolet (UV) radiation are thesun 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 themost common injuries among construction workers. These, and many chronicallydisabling 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 andslips off scaffolding and ladders are very common.

Biological hazardsBiological hazards are presented by exposure to infectious micro-organisms, to toxicsubstances of biological origin or animal attacks. Excavation workers, for example, can



develop histoplasmosis, an infection of the lung caused by a common soil fungus. Sincethere 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, maybecome infected with contagious diseases-influenza or tuberculosis, for example.Workers may also be at risk of malaria disease if work is conducted in areas wherethese organisms and their insect vectors are prevalent.

Social hazardsEmployment in construction sector is intermittent, and control over many aspects ofemployment is limited because construction activity is dependent on many factors overwhich construction workers have no control, such as the state of an economy or theweather. Because of the same factors, there can be intense pressure to become moreproductive. Since the workforce is constantly changing, and with it the hours andlocation of work, and many projects require living in work camps away from home andfamily, construction workers may lack stable and dependable networks of socialsupport. Features of construction work such as heavy workload, limited control andlimited social support are the very factors associated with increased stress in otherindustries. These hazards are not unique to any trade, but are common to allconstruction workers in one way or another.

Decreasing exposure concentrationThree general types of controls can be used to reduce the concentration ofoccupational hazards. These are, from most to least effective: engineering controls atsource, environmental controls that remove hazard from environment, personalprotection equipment provided to the worker.

Engineering controlsHazards originate at a source. The most efficient way to protect workers from hazards isto change the primary source with some sort of engineering change. For example, a lesshazardous substance can be substituted for one that is more hazardous. Water can besubstituted for organic solvents in paints. Similarly, non-silica abrasives can replacesand in abrasive blasting (also known as sand blasting). Or a process can befundamentally changed, such as by replacing pneumatic hammers with impacthammers that generate less noise and vibration. If sawing or drilling generates harmfuldusts, particulate matter or noise, these processes could be done by shear cutting orpunching. Technological improvements are reducing the risks of some musculoskeletaland other health problems. Many of the changes are straightforward-for example, atwo-handed screwdriver with a longer handle increases torque on the object andreduces stress on the wrists.

Environmental controlsEnvironmental controls are used to remove a hazardous substance from theenvironment, if the substance is airborne, or to shield the source, if it is a physicalhazard. Provision of flexible Local exhaust ventilation (LEV) may be used. The simpleand 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 UVradiation, and material that absorbs and reflects sound will provide some protection



from noise sources. Major sources of heat stress are weather and hard physicallabour. Adverse effects from heat stress can be avoided through reductions in theworkload, provision of water and adequate breaks in the shade and, possibly, nightwork.

Personal protectionWhen engineering controls or changes in work practices do not adequately protectworkers, workers may need to use personal protective equipment (PPE). In order forsuch equipment to be effective, workers must be trained in its use, and the equipmentmust fit properly and be inspected and maintained. Furthermore, if others who are inthe vicinity may be exposed to the hazard, they should either be protected orprevented from entering the area.

Eating and sanitary facilitiesA 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 theymay inadvertently swallow toxic substances transferred from their hands to food orcigarettes. A lack of changing facilities at a worksite may result in transport ofcontaminants from the workplace to a worker’s home. It is proposed to provideseparate temporary canteen and changing place for employees.
