STRUCTURAL FORM WORKS AND SAFETY CHALLENGES: ROLE OF BAMBOO SCAFFOLD ON COLLAPSE OF REINFORCED CONCRETE BUILDINGS IN NIGERIA

Bamboo scaffold serves as provisional structure to support people, materials,structures under construction and for maintenance works in most developing nations of Africa and Asia. But the risk posed by the use for construction in nations like Nigeria where collapse of reinforced concrete buildings is frequent have not been researched upon in the past. This research looks at the hazard posed by adopting bamboo scaffolds in construction in Nigeria. A total of 102 collapsed reinforced concrete buildings were revisited. Structural health monitoring tools, expert judgment and statistical measures were used. Results showed that over 20% of the collapse cases considered are at the risk of being caused by failure of overloaded bamboo scaffolds.
