Residential Damage & Income Loss Residential Damage Building Repair Cost Building Clean-up Cost Property Damage Residential Building Repair Cost Dhaka's categorization of building structures: Jhupri, kutcha, semi-pucca and pucca were considered. Pucca structures were further divided into economically weaker section (EWS), middle-income groups (MIG) and high-income groups (HIG). Building upgrades would reduce the number of jhupris and kutcha structures and a percentage of semi-pucca buildings will be transformed to pucca over time. Jhupri, Kutcha, semi-pucca structures are one-storied buildings, average pucca structure consists of two (EWS), three (MIG) or four (HIG) stories. Flood damage will be restricted only to the first floor. Building construction costs of different types of buildings were estimated from the ACC Help Home Building Calculator. Repair costs of Jhupri, kutcha, semi-pucca and pucca are 50%, 25%, 12% and 6% of the building construction cost respectively. Any inundation of depth > 0.25 meter for more than a day is expected to cause a minimum threshold proportional damage requiring repair that varies with the type of the building. Any building submerged for 10 days or longer at an inundation depth greater than 1.5 m would always require repair. The proportion of buildings needing repair decreases linearly for fewer days of inundation. Proportion of damage differs across inundation depth ranges. 08/12/2016 14
