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 10.1.4 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
10.1.5 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. 10.1.6 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
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. 10.2 During Post Operational Phase: In the proposed project, all necessary control measures will be taken during site preparation. 10.2.1 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.
