2.2.1.1 Storm water drains:Storm water drainage planning, domestic water planning and sewerage transfer andsewage treatment planning are critical aspects of residential projects.

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 runoff and presented in following table 2.3.

Calculation for Storm Water DrainQuantity of storm water

(a) Without projectArea of Catchment, ‘A’ : 69.9863 HaRun off Coefficient, ‘C’ : 0.6Maximum intensity of rainfall, ‘I’ : 40 mm/hrTherefore Q : 4.666 m3/sec

(b) With project :Area for catchment for roof and road : 60.816 Ha

Area of Catchment, ‘A’ : 60.816 HaRun off Coefficient, ‘C’ : 0.9Maximum intensity of rainfall, ‘I’ : 40 mm/hrTherefore Q = : 6.082 m3/sec

Area for catchment for open areas : 9.170 HaRun off Coefficient, ‘C’ : 0.6Maximum intensity of rainfall, ‘I’ : 40 mm/hrTherefore Q = : 0.611 m3/secTotal Discharge : 6.693 m3/secBut, Discharge, Q = A/V

Where,A= Area of the Drain,

V= Max. Permissible Velocity : 6m/sec for concretedrain

Area of drain, ‘A’ = Q/V : 1.115 m2

Taking depth of drain as 0.6 m at the starting point : 0.6Width of drain = Area/depth = : 1.859 m 1859 mm

Width of the drain is to taken 1859 mm and depth varies according to the slope of ground.

2.2.1.2 Water Availability:Water is required for the construction as well as during occupation stage as the same isan important resource. The water requirement during occupation stage in the order of1476.5 KLD. The water resource available with the Municipal authorities was studiedto identify the source and feasibility. The water resource both domestic water andsewage is dealt by the Hyderabad Metropolitan water supply and Sewerage Board(HMWSSB) in the GHMC area. The HMWSSB has been maintaining the water supplyresources for Hyderabad along with the treatment of wastewater. The resourcesavailable with the HMWSSB are presented in table 2.3.

SEWAGE TREATMENT PLANTSewage treatment plant based on Moving bed bio reactor system (MBBR) technologyThe moving bed biofilm process combines the technologies of activated sludgeprocesses and biofilm processes. The moving bed biofilm process is frequently usedwhen space is an issue. High-rate biofilm systems such as the Kaldnes Moving BedReactor (KMB) or the NATRIX technology are highly efficient in removing the solubleorganic and nitrogen load.

Moving bed bio reactor system (MBBR)The KMB and the Natrix process are suspended carrier biofilm processes. They arebased on the use of plastic carrier media, which are kept in suspension and continuousmovement in the treatment reactor. Excess biomass sloughs off from the media and iswashed out of the process with the treated effluent.



Several process combinations have been realised in upgrading activated sludgetreatment plants. However, it is also possible to realise hybrid solutions using thebiofilm carriers in the existing tanks without any retrofitting.

When a pure KMB process is employed, a typical overall treatment design consists ofpre-treatment (screening) followed by one or more MBBR tanks, where the degradationprocesses of soluble matter take place. The final stage of the treatment is normally theparticle separation.

The Treatment plant will consist of the following units:

1. Bar screen channel with Bar screen2. Oil and grease trap integrated in the bar screen channel3. Equalizations tank with aeration/ mixing4. Aeration tank with fine pore diffuser membranes5. Secondary clarifier with mechanical rake6. Clarified water tank with aeration/ mixing7. Pressure sand filter8. Activated carbon filter9. UV10. Final treated water holding tank

8. ENVIRONMENT MANAGEMENT PLAN

The project is envisaged to develop 69.99 Hectares in Survey No. 387, 388 & 394 to404, Kondakal, Shankarpally, Ranga Reddy District, Telangana. The village has a numberof layouts and rapidly turning into a residential zone for various types of socio economicsectors.

8.1 PROJECT DETAILSThe project will be spread over an area of 69.99 Hectares in Survey No. 387, 388 & 394to 404, Kondakal, Shankarpally, Ranga Reddy District. The site is surrounded by openlands in west direction. An existing 18m proposed to be widen 30 m wide road in westdirection connecting Shankarpally road. The nearest railway station is the Shankarpallyrailway station located at a distance of 6.8 km.

It is proposed to provide 1067 residential plots of various types along with amenities.The water requirement of the project during occupation will be drawn from HMWSSB.Sewage treatment plant will be provided to treat the wastewater. Water conservationmeasures will be incorporated in the plumbing designs. Water recycling/reuse will beadopted by way of using treated water for toilet flush systems, and green beltdevelopment. The treated effluent and storm water will be let-out into the stormwater drains till such time the municipal drains and sewer lines are made available inthe area by the planning body GHMC. The required power will be drawn from theTRANSCO and the energy requirement will be optimized by adopting energy efficientdesign for lighting; Solar Energy will be used for fencing, and other areas whereverfeasible economically.

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

8.3 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 – 300 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 the air



quality and in worst concentrations are falling within the site, and the results are with inthe prescribed limits.

Impacts on Noise QualityImpacts on noise quality during construction stage will be significant. Hence theconstruction near the habitation is proposed only during daytime. 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 residential by HMDA. Mitigation measures shall be adopted to avoid thesame. 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 thenegative 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 impervious surface,and storm water sumps will be provided as mitigation measure. The design of the stormwater drain will consider the additional runoff. The urban storm water joining thestorm water drains may carry pollutants from impervious surfaces

Impact on Ground Water ResourcesGround water shall be drawn during construction & occupation phase. Exploitation ofground water 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 Human Use ValuesThe dominant land use in the area is open plots, and expected commercial space willincrease the pressure on the residential localities. There is no additional requirementand 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.

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

8.4.1 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.

8.4.2 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.

8.4.3 Occupation 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 HMDA/GHMC. The management in operation stage willessentially entail maintenance of sewage treatment plant, maintenance of utilities, andmonitoring activity in the project site. Monitoring for pollutants specified in theMonitoring Plan will 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 8.1.

8.5 IMPLEMENTATION ARRANGEMENTSThe responsibility of implementing the mitigation measures lies with M/s SSC- DSRProject during design stage while the responsibility lies with the cooperative owner’ssociety. Implementation schedule will be worked for phase wise implementation of themitigation measures after completion of detailed designs. In the pre-constructionphase of the project the supervision consultants shall review the EMP to identifyenvironmental 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 completionof detailed designs.

8.6 INSTITUTIONAL STRENGTHENINGThe management of M/s SSC- DSR Project will evaluate the organizational structurewith respect to inadequacies in implementing the environment management plans.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 SSC- DSR Project will have little role to play in environment management. Hence itis suggested to explore the possibility of co-opting a member from M/s SSC- DSR Projectinto these societies so as the spirit of environment management plan is not lost. Thecommon areas, electrical supply, street lighting, open space of central green will be



taken over and managed by the HMDA/GHMC and TRANSCO. The role of residents islimited to being stakeholders with little say in the day-to-day matters; the townplanning agencies and the government must address this issue.

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

8.7 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 housing projects; Liase with State and Government of India on fiscal policies to reduce environmental

pollution from housing activity.

8.8 ENVIRONMENTAL MONITORING8.8.1 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.

8.8.2 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.

8.8.3 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.

Environment monitoring of the parameters involved and the threshold limits specifiedare discussed below.

8.8.4 Ambient Air Quality (AAQ) MonitoringAmbient air quality parameters recommended for road transportation developmentsare Respirable Particulate Matter (RPM), Suspended Particulate Matter (SPM), Oxidesof Nitrogen (NOX), Sulphur Dioxide (SO2) and Lead (Pb). These are to be monitored atdesignated locations starting from the commencement of construction activity. Datashould be generated over three days at all identified locations in accordance to theNational Ambient Air Quality Standards (table 8.2) location, duration and the pollutionparameters to be monitored and the responsible institutional arrangements aredetailed out in the Environment Monitoring Plan.

8.9 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 SSC- DSR Projects. All reporting by the contractor and SupervisionConsultant shall be on a quarterly basis. The M/s SSC- DSR Projects shall be responsiblefor preparing targets for each of the identified EMAP activities. All subsequent reportingby the contractor shall be monitored as per these targets set by the M/s SSC- DSRProject before the contractors move on to the site. The reporting by the Contractor willbe a monthly report like report of progress on construction and will form the basis formonitoring by the M/s SSC- DSR Projects either by its own Environmental Cell or theEnvironmental 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 BUDGETThe environmental budget for the various environmental management measuresproposed in the EMP is detailed in table 8.6.

8.11 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 SSC- DSR Projects. It would generatelocal employment if the plantation, upkeep and maintenance of the green belt areentrusted 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 SSC- DSR Projectswill have greenery by way of avenue plantation and central green. The scheme ofplantation and the figures are presented in mitigation chapter. The upkeep and themanagement of the greening is 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 round 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 thenursery, 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 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. (ii) 3 Nos. 25x25mmMS flat rings fixed as per design (iii) 15 Nos. 1.55 metres long 6mm dia bars. Each ringshall be in two parts in the ratio of 1:2 and their ends shall be turned in radially for alength of 4 cm at which they are bolted together with 8mm dia and 30mm long MSbolts and nuts.

The vertical angle irons shall be welded to rings along the circumference with electricplant 15 Nos. bars shall be welded to rings at equal spacing along the circumference ofring. The lower end of the angle iron verticals shall be splayed outwards up to an extentof 10cm. The lower end of the flat of lower ring shall be at a height of 45cm. and upperend of the flat of top ring shall be at the height of 2.00 metres. The middle ring shall bein the centre of top and lower ring. The bars shall be welded to rings as shown in thedrawing. The entire tree guard shall be given two coats of paint of approved brand andof required shade over a priming coat of ready mixed primer of approved brand.



(i) Nursery StackPlanting should be carried out as soon as possible after reaching the site. Whereplanting must be a necessity and/or be delayed, care should be taken to protect theplants from pilfering or damage from people animals. 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.
