2.2.1.1 Storm water drains:Conservation of water resource is most important aspect of the project duringconstruction and occupation phases. Storm water drainage planning, domestic waterplanning and sewerage transfer and sewage treatment planning are most essential.

Calculation for Storm Water DrainQuantity of storm water(a) Without projectArea of Catchment, ‘A’ : 2.8894 HaRun off Coefficient, ‘C’ : 0.6Maximum intensity of rainfall, ‘I’ : 40 mm/hrTherefore Q : 0.193 m3/sec(b) With project :Area for catchment for roof and road : 1.192 HaArea of Catchment, ‘A’ : 1.192 HaRun off Coefficient, ‘C’ : 0.9Maximum intensity of rainfall, ‘I’ : 40 mm/hrTherefore Q = : 0.119 m3/sec

Area for catchment for open areas : 1.697 HaRun off Coefficient, ‘C’ : 0.6Maximum intensity of rainfall, ‘I’ : 40 mm/hrTherefore Q = : 0.113 m3/secTotal Discharge : 0.232 m3/secBut, Discharge, Q = A/VWhere,A= Area of the Drain,V= Max. Permissible Velocity : 6 m/sec for concrete drain

Area of drain, ‘A’ = Q/V : 0.039 m2

Taking depth of drain as 0.6 m atthe starting point : 0.6Width of drain = Area/depth = : 0.065 m 65 mm

Width of the drain is to taken 65 mm and depth varies according to the slope ofground.

Rainwater Harvesting StructuresStorm water drains are provided with recharge pits which will act as flow dissipatersand also as infiltration trenches to ensure percolation of water and enhance the groundwater table. The roof waters are channeled through storm water drains, which areconnected with water harvesting pits. Rain Water Harvesting Pit shown in fig 2.4andContour plan is shown in fig 2.5

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 by



means 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 theprocess 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 advantagesand best features of Trickling filters, Rotating biological contractors, activated sludgeprocess and submerged fixed film reactors while eliminating the drawbacks of thesesystems. The plants are more compact and more energy 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.

Design StageThe total number of people anticipated to stay in the housing project is in the range of2500-3500. The anticipated solid waste/garbage is in the range of 500 g/head, and thetotal garbage will be in the order of 1328 kg/day. The present practice is to collect thegarbage from each flat using the services of NGO’s and send it to the segregation pointby cycle-rickshaws. The area of Serilingampally has no solid waste disposal plan,however residents of the surrounding layouts are sending their solid waste through theGHMC appointed NGO for collection. Table 2.10 presents the anticipated garbagequantity after occupation. The responsibility of garbage collection and disposal lieswith municipality, however the project authorities propose to educate the residents tosegregate the waste at source before disposal.

The water requirement of the projectduring operation will be drawn from HMWSSB. Sewage treatment plant will beprovided to treat the sewage. Water conservation measures will be incorporated in theplumbing designs. Water recycling/reuse will be adopted by way of using treatedsewage for green belt development. The rainwater will be let-out into harvesting tankand excess discharged into storm water drains. The required power will be drawn fromthe TRANSCO. Solar Energy will be used for fencing, and partially for hot water in theapartments. The designs of the apartments will also incorporate Indian Architecturalprinciples of “Vastu” as the market demands the same. Construction material will bedrawn from local sources.

5.2 MAJOR FINDINGS OF THE EISAn EIS/EMP was conducted and the major findings of the EIS study are presentedbelow;

5.3 ENVIRONMENTAL IMPACTS

Impact 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 2 – 200 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 airquality 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. The impacts duringoccupation stage will be on the plots adjacent to the road. Construction workers will beprovided 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 very few trees within the project site due to anthropogenic pressures. Theproject will enhance the aesthetics of the site due to the provision of avenue plantationand central 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 may leadto pollution of water shed if allowed to join 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 GHMC. However the topography of the land being rockyplains involves cut and fill operations where there is an excess of cut . Erosion andsedimentation are impacts anticipated during construction. Mitigation measures shallbe adopted to avoid the same. The area development would increase the housingactivity in the surroundings, which is a positive impact, as barren lands will be used forproductive usage, and the negative impacts will be pressure on the infrastructurefacilities.

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 rainwater-harvesting structures will be provided as mitigation measure. The designof the storm water drain will consider the additional runoff. The urban storm waterjoining the storm water drain may carry pollutants from imperious surface.

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 resource



conservation. 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 residential, and expected commercial space willincrease the pressure on the residential localities. There is no additional requirementand or acquisition of land. The project authorities will provide road safety measures toreduce risk of accidents in the internal roads. The impact on Human use values ismarginal.

5.4 ENVIRONMENTAL 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 permissions, obtain allnecessary permissions from various statutory authorities after obtaining the relevantpermissions.

5.4.2 Construction stageThis will be the most crucial and active stage for the Environmental Management Plan.In addition 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 project will be part of the supervising Contractors responsibility.

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 who 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 Municipality. 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 efficiency ofthe protection/mitigation/enhancement measures implemented, this will help verify or



refute the predictions made as a part of the impact assessment. Thus, it will complete avery important feedback loop for the housing 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 AparnaConstructions & Estates Pvt. Ltd., during design and construction stages while theresponsibility lies with the cooperative owner’s society and the Balanagar authoritiesduring occupation stage. All construction activities taken up by the project authoritieswill be supervised by the Supervision Consultant (SC). Implementation schedule will beworked for phase wise implementation of the mitigation measures after completion ofdetailed designs. In the pre-construction phase of the project the supervisionconsultants shall review the EMP to identify environmental and social issues and arriveat a suitable strategy for implementation. The activities to be carried out and the targetdates will be worked out after completion of detailed designs.

5.6 INSTITUTIONAL STRENGTHENINGThe management of M/s Aparna Constructions & Estates Pvt. Ltd., will evaluate theorganizational structure with respect to inadequacies in implementing the environmentmanagement plans. The housing project is typical as the responsibility of managementlies with the owners/residents during occupation stage. The owners form a cooperativesociety/association to manage the utilities and common areas in a normal case. Thecommon areas, electrical supply, street lighting, open space of central green will betaken over and managed by the local body and TRANSCO. The role of residents islimited to being stakeholders with little say in the day-to-day matters; this issue mustbe addressed by the town planning agencies and the government.



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.

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

environmental pollution from housing activity.

5.8 ENVIRONMENTAL MONITORING

5.8.1 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.

5.9Reporting 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 turnshall report to the M/s Aparna Constructions & Estates Pvt. Ltd.,



All reporting by the contractor and Supervision Consultant shall be on a quarterly basis.M/s Aparna Constructions & Estates Pvt. Ltd.,shall be responsible for preparing targetsfor each of the identified EMAP activities. All subsequent reporting by the contractorshall be monitored as per these targets set by the M/s Aparna Constructions & EstatesPvt. Ltd.,before the contractors move on to the site. The reporting by the Contractorwill be a monthly report like report of progress on construction and will form the basisfor monitoring by the M/s Aparna Constructions & Estates Pvt. Ltd.,either by its ownEnvironmental Cell or the Environmental Specialist hired by the Supervision Consultant.

Monitoring of facilities at construction camps Monitoring of air, noise, soil and water parameters including silt load Monitoring of survival rate of plantation. Monitoring of cleaning of drains and water bodies.

5.11 Horticultural and Landscaping Works

(a) ScopeThe Horticultural and Landscaping works may be entrusted to a contractor. It wouldgenerate local employment if the plantation, upkeep and maintenance of the green beltwere entrusted to local VSS bodies. Detailed drawings and designs of landscaping willbe drawn after completion of the detailed designing. The following precautions mustbe taken while undertaking horticulture and landscaping works. The project will havegreenery by way of avenue plantation and central green. The scheme of plantation andthe figures are presented in mitigation chapter. The upkeep and the management ofthe greening are presented as follows:

b) Materials

Plant Materials

Plant Materials shall be well formed and shaped true to type, and free from disease,insects and defects such as knots, sun-scaled, windburn, injuries, abrasion ordisfigurement.All plant materials shall be healthy, sound, vigorous, free from plant diseases, insectspests, 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 ofroots or ball of earth shall be increased in proportion to the size of plant.Deliver plants with legible identification labels.

Top Soil (Good Earth)

Topsoil or good earth shall be a friable loam, typical of cultivated topsoils of the 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 5.5.

Fertiliser

Measurement of sludge shall be in stacks, with 5% reduction for payment. It shall befree from extraneous matter, harmful bacteria insects or chemicals. (Subjected tosafety norms).



Root System

The 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.

(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 Shrubs

Trees 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 Pits

Tree 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 Filling

The 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.

Planting

No 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. 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.

Staking

Newly 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 across bar to which the stem is attached. Suitable for bare- rooted orBall material.

(c) A single stake driven in at an angle at 45 degrees and leaning towardsthe prevailing wind, the stem just below the lowest branch beingattached to the stake. Suitable for small bare- rooted or Ball material

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



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

Tying

Each tree should be firmly secured to the stake so as to prevent excessive movement.Abrasion must be avoided by using a buffer, rubber or Hessian, between the tree 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.Watering

The 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.

Fertilising

Fertilising 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 ortussle.

(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 5:1 (5parts of stacked volume of earth after reduction by 20%: 1 part of stacked volume ofsludge after reduction by 5%.)

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) GrassingPreparation

During period prior to planting the ground shall be maintained free from weeds.Grading and final weeding of the area shall be completed at least three weeks prior 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.

Soil

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

Sowing the grass roots

Grass roots (cynodon, dectylon or a local genus approved by the Landscape Architect)shall be obtained from a grass patch, seen and approved before hand.

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

Execution

Small 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.

Maintenance

As 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 5 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.

Rolling

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

Edging

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

Fertilising

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

Watering

Water 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.

Weeding

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

Cultivating

The Landscape Contractor shall maintain all planted areas within Landscape 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 Repairs

Upon 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 Guards

Where 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 5mm 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.

(j) 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.

(k) 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

would conserve the natural resource and also reduce the pressure on other users.Typical lists of water conservation measures are presented as follows;



Water Saving MeasuresThere are a number of ways to save water, and they all start with you.

1) Check your sprinkler system frequently and adjust sprinklers so only your lawn iswatered and sidewalk, or street.

2) Avoid planting turf in areas that are hard to water such as steep inclines andisolated strips along sidewalks and driveways.

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

4) Use the garbage disposal less often.

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

6) Check your water meter and bill to track your water usage.

7) Always water during the early morning hours, when temperatures are cooler, tominimize evaporation.

8) Wash your produce in the sink or a pan that is partially filled with water instead ofrunning water from the tap.

9) Use a layer of organic mulch around plants to reduce evaporation and savehundreds of liters of water a year.

10) Use a broom instead of a hose to clean your driveway and sidewalk and save up to300 liters of water every time.

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

12) Water your lawn in several short sessions rather than one long one. This will allowthe 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) When you shop for a new appliance, keep in mind that one offering severaldifferent cycles will be more water and energy-efficient.

16) Install low-volume toilets.

17) When you clean your fish tank, use the water you’ve drained on your plants. Thewater is rich in nitrogen and phosphorus, providing you with a free and effectivefertilizer.

18) Water small areas of grass by hand to avoid waste.

19) Put food coloring in your toilet tank. If it seeps into the toilet bowl, you have a leak.It's easy to fix, and you can save more than 2250 liters a month.

20) Use porous materials for walkways and patios to keep water in your yard andprevent wasteful runoff.

21) 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.

22) Install a rain shut-off device on your automatic sprinklers to eliminate unnecessarywatering.



23) Choose water-efficient drip irrigation for your trees, shrubs, and flowers. Wateringroots is very effective, be careful not to over water.

24) Grab a wrench and fix that leaky faucet. It’s simple, inexpensive, and can save 525liters a week.

25) Cut back on the amount of grass in your yard by planting shrubs and ground coveror landscaping with rock.

5.13Energy Efficiency Measures in a Typical Household

5.13.1 Hot Water

Repair leaky faucets. Reduce the temperature setting of your water heater to warm (500 C). Add an insulating blanket to your water heater. Install low-flow showerheads. Wash clothes in warm or cold water using the appropriate water level setting for

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

5.13.2 Major Appliances and Other Appliances

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

Maintain stand-alone freezer at 0 F.

Choose a refrigerator/freezer with automatic moisture control.

Use toaster ovens or microwave ovens for cooking small meals.

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

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

Run the dishwasher only with a full load of dishes.

Air dry dishes in a dishwasher.

Shut down home computers when not in use.

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

Replace aging major appliances, TVs and VCRs when needed, with energyefficient models. Replacing a 1970s refrigerator with an energy efficiencyrefrigerator. This can save over 2,000 kWh per year. This will also reduce carbondioxide emissions by over 2,000 pounds every year.

Increase Air Conditioner thermostat by 3 degrees F. This can save over 900 kWhper year, annually and over 900 pounds of carbon dioxide each year. Dependingon the size of your home, you can save 3% on your cooling costs for every degreeyou raise your thermostat in the summer. Raising the thermostat from 73 to 75 Fdegrees can reduce cooling costs by 15%.



Make sure your air conditioner is the proper size for the area you are cooling. Anair conditioner that is too large will use more electricity than needed; an airconditioner that is too small will have to work harder to cool a space. Therecommended Air conditioners based on the room size are as follows:

Area To Be Cooled (sq. ft.) Capacity (BTU/HR)100 to 150 5,000150 to 250 6,000250 to 300 7,000300 to 350 5,000350 to 400 9,000400 to 450 10,000450 to 550 12,000500 to 700 14,000700 to 1,000 15,000

Only run the washing machine, dryer, and dishwasher when you have full loads.Cool only the rooms you use and utilize fans when the temperature is moderate.

5.13.3 Lighting

Turn off lights when not in use.

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

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

Replace the five most frequently used incandescent light bulbs with compactfluorescent bulbs. This will save over 500 kWh per year, and over 500 pounds ofCO2.

It is proposed to provide CFL units in the common areas, bathrooms, and central greenarea to conserve electricity by the project authorities. The average usage of 4 CFLs ineach dwelling, and the total energy savings from the project and the overall reductionin pollutants is presented in the following table;

5.14 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 the



construction 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 andmitigate 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 in



injuries and fatalities. Ladders have limitations; allows only one person to work, climb,and carry materials or work with one hand, restricts movement, should be secured 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 within the siteand from outside the site. The most common causes of onsite traffic incidents are; baddriving technique, carelessness, carrying unauthorized passengers, poor maintenance ofvehicles, site congestion, overloading, and uneven ground and debris. It is proposed toensure that all drivers have appropriate driving license, routes are planned, marked andleveled, enlisting additional workers during reversing, switching off the engine duringidling, 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 forsafety.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, candevelop 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, a



two-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 protectionfrom noise sources.Major sources of heat stress are weather and hard physical labour.Adverse effects from heat stress can be avoided through reductions in the workload,provision of water and adequate breaks in the shade and, possibly, night work.

Personal 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.
