Rather, it is about shouldering a much larger social responsibility where in a person s life earnings are at stake for a shelter of his dreams or a commercial base to flourish. Therefore, the buildings should be constructed on the stronger Page No.: 1

5 foundation of faith and commitments. A builder should not collect money without getting fully satisfied about the title and all the statutory clearances. Then, we should think about the needs of the end users of the apartments, shops and offices.we should not aim at constructing buildings with just brick and mortar, but with feelings and a goal to deliver the best. We must make a difference in the life of every person and uplift society benchmarks so that we are able to create a better tomorrow for everyone. Our organization would first like to become a better citizen of the society before becoming World s best company. We should be careful in looking at the welfare of every worker and laborer for it is they who construct our houses brick by brick. We should also not forget about our planet that has permitted us to live on it. Thus, our buildings should be environment friendly causing least burden on the natural resources. In a nutshell, we should own up responsibilities, create benchmarks without caring for costs, follow commitments and success will follows us.

24 10.0 Environmental Management Plan: Environmental pollution is inevitable during the construction phase. The project proponent should take appropriate steps to control pollution during construction phase. The following are the factors requiring control during construction phase During Construction Period: Site Preparation In the proposed project, all necessary control measures will be taken during site preparation. The soil type in the area of project site area is Black soil. Sparse vegetation is observed in small portion of the Project area. Hence there will not be much removal of top soil during construction activities. To keep the damage to top soil minimum, excavators will be utilized for construction Top soil excavated during construction activities will be stacked at safe place for reuse at a later stage of construction Air Environment: Dust is the major emission during the construction period. The following control measures will be followed during the construction period Application of dust suppressants will be done Locally available gravel will be applied to the roads and lots, to prevent the dust emanation Measures will be taken to cover the stored materials to prevent the dust emission during high winds Speed of the vehicles in the project area will be limited 20 Kmph Rescheduling the works during high speedy winds Inspection will be done for use of covering sheet to prevent dust dispersion at buildings site Page No.: 21

25 Water Environment Conceptual Plan Water required during the construction the residential complex will be met from the ground water resources. Total water requirement during construction period will be 25 KLD and construction period lasts for period of 36 months. The following control measures will be taken to reduce the reduce the water requirement during construction Curing water will be sprayed on concrete structures; free flow of water will not be done for curing. After liberal curing on the first day, all concrete structures will be painted with curing chemical to save water. This will stop daily water curing hence save water. Concrete structures will be covered with thick cloth/gunny bags and then water will be sprayed on them. This will avoid water rebound and will ensure sustained and complete curing. Ponds will be made using cement and sand mortar to avoid water flowing away from the flat surface while curing. Waste water management during construction Waste water generation will be minimized by following above control measures Sanitary waste water generated during construction stage will be sent to septic tank followed by soak pit Noise Environment The main sources of noise in the process of construction activities will be cement concrete mixing, welding, aluminum channel folding, drilling and DG sets etc. Diesel generator sets will be provided with integral acoustic enclosure at the manufacturing stage itself Equipment like earmuffs, earplugs etc. will be used for hearing protection for workers. Page No.: 22

26 Land Environment: Conceptual Plan Proper planning and management during construction period is very much vital. We proposed to implement the following control measures to mitigate the waste generation Delivery of material on site will be done over a durable, impervious and level surface, so that first batch of material does not mix with the site surface. Availability of covered storage will be assured. The recyclable items like metal, plastic will be sent to recyclable industry, and rest of this scrap will be stored in a covered area. Wherever materials (aggregates, sand, etc.) are more likely to generate fine airborne particles during operations, nominal wetting by water will be practiced. Workers / labour will be given proper air masks and helmets. Skilled labour and good workmanship will be employed for judicial utilization of materials and minimizing the waste. Proper estimate of material will be done to minimize the undue wastage. Contaminated runoff from storage will be captured in ditches or ponds with an oil trap at the outlet. Materials wasted on site will be reused at the same place Waste management & recycling The construction waste includes debris, concrete (often recycled and reused at the site), steel and other metals, pallets, packaging and paper products, fluorescent tubes, wood beams, joists, studs, baseboards, cabinets and cupboards, railings, brick, doors and casings, interior windows, bathroom fixtures, light fixtures, ceiling grid and tile, furnishings etc. Waste recycling Plan Waste and recycling plans will be developed prior to beginning construction activity. The plan aims at identifying wastes to be generated, and designate handling, recycling and disposal method to be followed. Page No.: 23

27 Handling Handling of waste material requires special precautions such as personal protective equipment and special procedures to prevent the injury. Safe operating methods will be developed for waste collection, storage, and disposal operations in a manner to protect the health and safety of personnel, minimize environmental impact and promote material recovery and recycling. Waste Segregation Gross segregation of construction wastes into roadwork materials, structural building material, salvaged building parts and site clearance wastes will be done and additional segregation will be done to facilitate reuse/ recycling. Storage Adequate provision will be made for storage of solid waste and for easy access to the dustbins for labors from source to the place of storage, and from the place of storage to a collection point specified by the waste collection authority and/or contractor Three colors of wheeled bins: Dark grey for inert waste, Green for wood and ply waste and Blue for hazardous waste will be used. A minimum of 4% of the total site area will be allocated for storage and pretreatment of the waste. This storage area will be covered to prevent any impact on surrounding During Post Operational Phase: In the proposed project, all necessary control measures will be taken during site preparation Air Emission Management: During operation of the proposed Residential complex, the emissions will be mainly from DG Sets which will be used for backup power supply and vehicles. Emissions will be mainly Particulate matter, Hydrocarbons, Nitrogen dioxide and Carbon monoxide. Page No.: 24

28 The following control measures will be taken up during the operation All the internal roads will be grass paved. This will reduce the dust generation due to the vehicular movement Stack of adequate height will be provided to the DG Sets as per CPCB guidelines Green belt will be developed in the premises of complex which will act as sink for air emissions Hence there will not be any impact on surrounding environment due to the air emissions from the proposed complex.
