All 10,344 window panes were replaced by single-paned, heat-treated panels, helping inflate the cost of the project. The primary objective of the examination is to obtain an accurate diagnosis as a basis for a report. This study has revealed that more than 70% of the reported cases of foundation collapse and failure in Nigeria stemmed from the informal sector.

The main framing elements, columns, and beams of the building were made from steel and the floors were constructed of reinforced concrete. A foundation failure is when it is no longer able to support the full weight of the building due to movement of soil and excessive settlement. The drivers of structural failure can include design defects by engineers or architects, incorrect or substandard construction materials, inspection failures to identify building and. Most of the information about the disaster comes from ancient texts, such as ones by Tacitus and by Tiberius, but they tell a singular story: When 50,000 people flocked to Atilius' stadium to watch a gladiator fight, 20,000 of the audience members fell to their death as the seating collapsed. When all efforts to support the building failed, the last resort was used, which involved very costly soil solidification by freezing the soil. The building eventually had to install screens at certain points to prevent the reflection of direct sunlight. Initially, people suspected terrorism, as noted by police at the scene, but an investigation quickly dispelled that concern.
