BEIRUT PORT EXPLOSIONS RESPONSE Beirut Municipality Rapid Building-Level Damage Assessment Introduction and purpose Building Coding The Port of Beirut explosions (4 August 2020) resulted in Adapted from the Applied Technology Council’s Field Manual extensive damage on multiple levels – the loss of life, injury (ATC-20-1), the following building coding to categorize damage and the destruction of vast tracts of urban fabric within the and habitability was adopted: municipal boundaries of Beirut and Bourj Hammoud. Led by Total collapse1 the Municipality and Governor of Beirut, UN-Habitat supported Buildings that experienced total collapse. a rapid damage assessment at the building level (exterior visual Unsafe / evacuate survey). Buildings that are structurally unsound and require evacuation. The assessment covered all building types within an immediate Restricted use 2km radius of the blast, dividing them into four categories (total Buildings that incurred considerable damage in their collapse, unsafe / evacuate, restricted use, safe / minor damage, architectural components (falling architectural elements that unclassified) in order to understand the extent of damage, might affect public safety). particularly structural impacts, as well as immediately identifying Safe / minor damage buildings at risk of collapse and in need of evacuation. The Buildings that were subject to minor defects, such as broken assessment provides a basis on which to formulate recovery glass. Buildings that were not affected at all also fall under this and reconstruction measures, with regards to building damage category. rehabilitation. Unclassified Buildings that were not surveyed.
