Padma Multipurpose Bridge Project

ProjectActivitiesEnvironmentalImpactsMitigation/Compensation Measureshas commenced, piling works should cease until they have left. It is alsorecommended that adoption of a ‘soft start’; using a low energy start to theoperations would give dolphins an opportunity to leave the area. In addition,the following mitigation measures are proposed: Gradually ramp up the sound levels to scare the dolphins awaybefore piling proper commencesUse pingers upstream and downstream to chase away dolphinsMonitor area for dolphins to ensure they are well away from thepiling site – scare them away if they are two close to the site usingpingersBudget,USDInstitutionalResponsibilitiesImplementationSupervisionImpact on turtle andgharial habitatLimit the construction activity within the designated areasCheck the site for turtle or gharial trapped in, or in danger from civilworks and use a qualified person to relocate the animal.Monitor area to ensure they are well away from the piling site – scarethem away if they are too close to the site using pingersPart of civilworkscontractContractorCSC, PIUConstruction ofSuperstructureImpact of air noiselevels on endangeredand migratory birdsVegetation clearing onthe Char locatedalong the alignmentRisk of watercontamination withconcreteOccupational, healthand SafetyAcoustic enclosure should be placed to cover the hammer and theexposed pile to reduce the air noise. The air noise levels can be reducedto about 60 dB with these measuresAvoid to damage vegetation in the CharlandImplement ECPs 12 and 13 on Protection of Flora and Fauna Unused concrete should not be disposed into the river water. Unused concrete should be collected properly and disposed in thedesignated waste dumping site. Implement ECP 19 on Workers Health and Safety Provision of adequate lighting along the bridge alignment and in thearea particularly where construction works will take place Proper safety training for all participating in the construction works anddistribution of PPE (such as helmets, masks, safety shoes and goggles,rain coats, ear plugs etc.) to the construction labors, engineers.Included incivil workscontractIncluded incivil workscontractIncluded incivil workscontractIncluded incivil workscontractContractorContractorContractorContractorCSC, PIU,ExternalMonitorCSC, PIUCSC, PIUCSC, PIUAir pollution from Proper safety training for all participating in the welding works and Included in Contractor CSC, PIU8-16
