While a number of bridges, overpasses and buildings under construction fail each year, the catastrophic collapse of an occupied building absent a bomb or an earthquake is rare, and. In Nigeria, the common causes of building collapse have been traced to bad 10 fdesign; faulty construction; foundation failure; extraordinary loads, use of unqualified contractors and poor project monitoring and above all, lack of enforcement of building codes by the relevant Town Planning Officials (Badejo,2009; Falobi, 2009; Bamidele, 2000).

The collapse of the building occurred due to the development of punching shear mechanism around column E5. The width of the rock sliver, of unknown strength, was approximately 355 mm. The result can be irreparable damage such as concrete slab shifting and settling, cracks on foundation walls, shifting of the foundation structures, and/or loss of structural support of framing members. While a number of bridges, overpasses and buildings under construction fail each year, the catastrophic collapse of an occupied building absent a bomb or an earthquake is rare, and investigators are struggling to understand how it could have come with so little urgent warning.

Thus, it was concluded that the main reason behind the occurrence of cracks in the building was due to the effect of a large movement of the order of 102 mm. Researches have shown that most of the bridges collapse due to hydraulic reasons such as floods, carvings etc. The construction work should conform to design documents and construction procedures.
