3. Poormaintenance of buildings
4. Environmental problems and aging effects
5. Indiscriminate additions & alterations
6. Natural & manmade calamity

5. 1.Poorstructural design & specifications
-Densely spaced steel bars
-Segregated concrete at beamcolumn junction
-Honey combing of concrete

6. 2.Poorconstruction & overloading
with illegal mezzanine floors

7. PoorConstruction, Poorquality of materials used
& poorsupervision.
